How To Choose Tires For Your Jeep Wrangler! - 33" vs 35" vs 37" Tires
Are you considering changing the tire size on your Wrangler? In this video, Ryan will walk you through everything you need to know when choosing a larger sized tire, the pros and cons, and three tires which we highly recommend.
To start things off, we will show you three Wranglers with three sizes of tires: 33-inch, 35-inch, and 37-inch. With differences in tire size come pros and cons which you will need to consider before making your purchase. After talking you through a few comparisons, we will then show you the differences in how these tires perform on and off-road! You'll see how the tire sizes perform differently and learn what tire size might be best for you and your rig!

33s strike a good balance without messing with gearing especially if you use your jeep for everyday use
On the short Wranglers, you can 35 inch without regearing because they are much lighter and are a bit more forgiving with the larger wheels. The four door lose a lot of pep with 35 inch tyres. However, the short wheel base Jeep was a 2001 Wrangler TJ and the long wheel base Jeep was a 2011 Wrangler Sahara JKU. The engines were completely different. The TJ engine is much stronger than the anemic 3.8 Pacífica engine.
Indrid Cold there’s a long wheelbase TJ too I think it’s referred to as an LJ
Put 33 on mine, had to change gear. Loss of tork was awful in the manual trans.
@@indridcold8433 The 3.8 engines don't do a lot offroad without breaking. The 3.6 is better than the 3.8 but the 4.0 is 10x better than both.
@@spydergs07 Agreed the 3.6 Pentestar engine is superior to the 3.8 Pacifica in every way possible. The AMC 242ci I6 (Powertech 4.0) is the best offroad, low rev, high torque, supernatural durability engine out of the three. The best engine for highway use is the 3.6 litre Pentestar and can be successfully used off road as well. The 3.8 is... The 3.8 is the best for a minivan.
I look at modified Jeeps so frequently that 35s have started to look stock to me lol
I know, right...crazy, isn't it?
I have a 2018 JK, (came with 4.1 gear ratio), 2" MOPAR lift, NITTO 285x75x17 stock wheels, a little rubbing. Getting KMC Enduro rims this week. Should have gotten the Nitto 35's to begin with :-( This is my Fun Driver, since my police cruiser is my daily.
@@ifp123 if you are rubbing with 34x11 a 35 isn't going to fit.
My 1st comment was 6 months ago; I now have KMC wheels, Nitto 35's - no rubbing @User Name
@@ifp123 Do those wheels have some insane backspacing and offset or something? I rubbed 35s with 3" of lift.
I've got an '02 TJ (not a JK), but I run 35" Mickey Thompson Baja MTZ (LT315/70R17) tires with a 5-1/2" Rubicon Express long arm lift. With 4.88 gearing, I am pleased with the on-road as well as off-road performance.
The first Jeep that went over the log had the cut tree limb pointed directly up, the second Jeep had the log with the tree limb placed in a different orientation. Obviously this made no difference in the comparison as the 37" tall tire will provide more clearance but having the log oriented exactly the same would be a better apples to apples comparison. Otherwise , very informative in explaining the difference in tire size vs suspension lift.
You just talked me into going with 33's
same!
@@carghai9235 I disagree, I’m rolling 35s on my JL with a 2 inch lift and have no regrets. I didn’t regear and it still accelerates nicely maybe because it’s a 2.0 turbo. I would’ve gotten 37s but I have a Sahara, and it would’ve taken 4 inches of lift and the spare tire mounting gets tricky. Go with 35s!
@@ishdeepsingh2960 I will get 37s but I need to find tougher trials jeep is super capable
My Jeep jk has 3 inch lift and 275/75/18 maxxis RZR 32 inch tire
@@atvman1014 is your jeep too capable?
Great video! I run 285/70R17 (33") MTRs on my 2 door jk rubicon with 4.10 gearing. It's the perfect combo for me. I invested in skids and diff covers. Yes, I drag a bit, but can wheel all day with the big boys and then drive the highway for miles and miles without issue.
Awesome video and very informative. I am a brand new Jeep owner and doing research on what is the best fit for my Jeep regarding tires. You helped out a lot with your video. Thank you.
My 37 Nitto Trail Grapplers just arrived yesterday! After watching this, I can't wait to get them mounted/balanced and installed on my JKU with 3.5" lift this week!!!
Did u re-gear?
Great Job. Very informative and now I am convinced I need 40's. : )
2rajnel and Dana 60s to go with them.
Thats what I ended up doing! Its an awesome setup. I will recommend the PSC Sterring System to go with that, otherwise your gonna have a helluva time holding it on the fwy
Nah do ur self a favor get 54s
Thanks for the laugh this morning. I need that. Lol
You definitely don’t need 40’s
This is the best information on tires/wheels etc. It gives the measurement in both difference standards and also shows what they look like size by size. I haven't seen good comparisons before. For some reasons tire size is just confusing to me and this cleared up a lot. I plan on looking at more of their videos.
The thing that most people tend to miss is that there are different sizes of 33” or 35” tires. Each manufacturer varies in the actual height, but there is also a lot of variability in widths, which makes a huge difference in whether or not a tire will fit. For example, there are 35s in 10.50, 285, 12.50, 315, 13.50, etc. width specs, and more. The wider you go, the more challenging it will be to fit.
2016 jeep wrangler AT with 35inch Toyo R/T 2.5 AEV lift plus procal running stock 3.21 gears. it handles surprisingly well . great video.
Very informative I really like the side by side comparison great job!
This is super informative and helpful for me being a complete newbie to this type of thing! Thanks for such an awesome video!
We're super happy you found it helpful! Thank you for watching! -Zach
Great video. Thanks for the information
Great video! I'm running 35x12.50 Nitto Trail Grappler M/T's on 18x9 Method Race Wheels on our JK, but 37's keep popping in my head. I just finished up the rear part of my KJ lift today, I will be going from 235/70's on OE 16x7's up to 245/75 on 16x8's. I have the Renegade KJ so I've already got plenty of gearing, and some awesome Fox Shocks (thanks Jake!) No matter what tire size you go with, you will always want something bigger down the road.
Excellent tutorial, keep the great videos coming Extreme Terrain.
I run 33's on my YJ and never a problem, either clearing obstacles or mechanically. Good choice.
just as I was about to get 35" tires I found this video. And yes, 33" is more reasonable. thanks!
Excellent work as always. We went with 38" x 14.5" MT/R with Kevlar. - Avengers.
Very good video. Great content and very informative. Big thumbs up.
i got no lift on my jeep. rolling on 295/70/r17 nitto grappler mud terrains with 1.5 inch spacers. tires are a smooth ride on the highway once u break them in
Love this video. I'm currently on 32" duratracs with 11,000kms on them and no lift, but once its time for an upgrade I'll look into 33s or 35s with a 2.5" lift and regearing. I mainly use my jeep to get to and from solar fields and other construction sites without road access... and well lets just say my ex g/fs kia rio wasn't cutting it. lol Still waiting on the new exhaust though. :(
33s will not be much of an upgrade. Just got mine less than a month ago and already want 37s or heck...dare I say 42?
Had a 2010 JKU Rubicon. 2.5" lift, Poison Spyder flares all around. Minor pinch weld trim. And PCS Brawler rails. Regeared to 5.13. Ran 37x12 YRXUS MT on 17' alloy. Handled Uwharrie very well. But I didn't do the most extreme stuff. This set up also handles the highway very well and the narrow city streets of Boston when I had to go up for a funeral. The River Raider Off Road engine to gas tank skud plate added protection and improved highway aerodynamics. Got the same MPG as stock.
This was the best vid for my questions on tires.
No one ever talks about the effect larger tires have on stopping distances. I felt a huge difference just going up to 33's
Tom Edgar that's common sense just upgrade you're brakes
Bigger tires = big brake kit
@@Joegoldberg7nothing money won’t fix…
@@Joegoldberg7 what upgrades they have on the brakes. Looking to upgrading my brakes making to much noise.
My favorite combination is 33s with 15 inch teelies on a TJ. I have a JK though, so I'll stick to 33 on 17 mags.
Great video, this is really helpful. Thanks!
I'm running 35 x 12.50 Cooper Discoverers on my 2012 Wrangler Unlimited on 20-inch Mayhem rims with 5-iinch body/suspension lift and couldn't be happier overall.
I just swapped from 32 inch street tires to 33 inch off road tires, very little difference in noise, better ride quality, and substantially better handling off road. Definitely enjoy the look and will probably lift it soon, just a bit. Thanks for an informative video.
Thanks for watching and happy to hear you're loving the 33s! -Zach
Growing up, I 'member that Jeeps "...weren't real Jeeps unless they had 31" tires or above..." That began to change with the TJ, which came off the factory with 30" Goodyear Wrangler A/Ts. The coil springs allowed for 31" tires with stock suspensions. The advent of the Rubicon further changed the rules with stock 31" rubber. I remember getting 31" narrow SuperSwamper Radials on stock rims and suspensions! Horrible noise, scary on wet pavement, but unstoppable off-road. These modern JKs are looking more grotesque than purposeful, too much of a fashion statement... One can compare the Jeeper scene with the motorcycle scene: from purist and functional, to poseur and f'ed up. What is the right tire for you? Whatever! It is always the driver that makes the Jeep, not the diameter of rubber or inches of lift. Jeep on, and remember to wave!!!!
The History of the Jeep tire, by Teo P.
@@Hay-tn6hz Hahaha, thank you! I can still remember reading an issue of 4Wheel can Drive Magazine, and it was such a huge deal that a Wrangler came out of the factory with 30" tires!
Crazy I just got into my own Jeep after driving my gfs for three years I’ve always waved and had people wave back ever since I bought mine like a week ago no ones waving lol
@@elipeko i always wave- it's just fun. but there are a lot of a-hole jeep owners who look for reasons to be grumpy- and not waving is one of them. i pass the same jacked up jeep every day on the way home from work, i always wave, he never does- now it's a game- i literally lean out the window waving like an idiot- at the very least I'll get him to laugh! 😅
I have a Jeep that I’m considering tire sizes for. Your information was very helpful. Will go with 33’s so I don’t have to mess with RE-gearing. Seems like the best compromise. Thanks again
Glad our video helped you out! 33s are definitely the best of both worlds. Bigger and more aggressive looking than stock, but not big enough to require regearing or other modifications. -Zach
currently running 37's on a 5-inch lift. Stock gears and axels. Fox reservoir shocks. Have no problem at all off-road.
For all of you asking what gearing I need for what size tires. Type Jeep JK gearing chart into your browser and it will give you charts for 3.8l engine with manual or automatic and 3.6l engine manual or automatic. Then you can figure out what gearing goes with what tire size you choose.
Deathadder097 I put a 2.5 lift kit with 35's I need to re gear my jeep
What price should you be looking at for a dealership to swap out the gearing? I know people say don't go with them because it can be more expensive, but it will hold your warranty.
Thank you for the great information. As someone who is new to jeeps, I’ve wondered what the pros and cons were to bigger tires. You answered a lot of my questions.
It's a good video Eddie, but realistically it all comes down to $$$, and I just don't mean purchasing the products either. Day to Day cost must be factored in when you start lifting and going bigger on tire size. You're going to spend a LOT more dollar day to day on fuel if you go bigger in any way. So ask yourself that question first, can you afford the day to day expense of the modification that you are choosing to go to, if so then mod it out. If not well, there's your answer. I use my JL as a day to day and have the 33 KO2's on it, this time I am leaving it alone. I go down plenty of trails no problem and when I am wheeling with the gang I learned the hard way it's cheaper to just "Go around the obstacle". I still have fun, I still go wheeling, camping, fishing etc..etc..I now just have more money in my pocket lol and believe it or not I enjoy my Jeep with 33's on it as much or more as I would with 37's on it. PLUS they last a whole lot longer which means I am saving huge amounts of $$$. Bottom Line. It's what you can afford or choose to afford when it comes to this issue. Jeep On Brother!
Thanks so much for the video. So informative. I have a 16 Tacoma on 31 KO2. But looking to either update to a 33 or 35. But the truck is a daily driver too so maybe the 33 would be better. Thanks again!
JKUR manual (4.11 gears) with just a EVO MFG leveling kit. Going with 35's, 1.5" wheel spacers and trimming the fenders+rock rail. IMO it's the best for my needs (low center of gravity, bigger tires and easy on the wallet)
Man that black rubicon looks mean !
I'd really love to see a video on the correct diff gear ratios for each of the tire sizes illusttated.
You need this gearing to maintain current effective ratio = (New tire Dia X existing gear ratio)/old tire dia.

! AWESOME ! Well Done Class ! Very Important Tips and Technical Information For a Beginner (Like Myself and Many ... Thousands ...More) . Nice Cars & Gears ! Thanks a Lot ! Best Regards !
running JL Sports S 2018 on 37's in D30 on 4.88 gear ratio, drives like a beauty!!! no issues! even had no issues fitting the 37x12.50R17 on -22mm off set with no lifts on it, no rubbing at all, i think our JL sits on the spacer cuz it seems higher than most jeep (of course the performace was way off 54mph on the techometer while the gps said 65 mph, had to regear it to 4.88 to return it to stock ability.
Now that the 2021 Rubicon JL comes with stock 33's I have to go bigger!
Increased risk of rolling, both on road and off road is a big consideration for me when choosing a lift and tire size. The taller you are, the quicker you flip. I liked the video. I'm running the minimum lift to get the minimum effective tire (for me, I felt 33" was the best balance). I'd love to be able to run a bigger tire, but I like to go fast and slide. There's no free lunch.
Everett Durst I feel the same way, do you even need to put a lift on with 33's
However, when you go up, you are supposed to go out so if you are making your truck taller, the proper way to do that is to make your truck wider at the same time. When done properly you are not at a greater risk of rollover, at least not enough to be concerned about.
thanks. I was planning on getting bigger tires. the stock was 245 75 17 . and i replace it with 265 Goodyear wrangler i like it and feels comfortable on road .
Ryan, I am glad you said something about gearing as most do not take that into consideration or do anything about it but I disagree with one point. Most JKUs out there today have the standard 3.21 gear ratio with the exception of the Rubicon and Willys Wheeler models. The stock 32" tall tire with the 3.21 and an automatic imo is not ideal from the start. Add a slightly larger 33" tire with an even wider foot print causing more drag, and the jeep will feel sluggish and not perform well at highway speeds meaning maintaining steady 75-80mph speeds are not like they should be and your foot will be on the pedal more that it should. My recommendation to anyone purchasing a new jeep, make sure you at least get the optional 3.73 gear ratio. It is a cheap option considering the cost to regear and In the end, you will happier even with the stock tires. If you want to go up to a 33, you will be fine. Get to the 35-37 range and then 4.10-4.56 is necessary. If you have an older 2007-2011 with the 3.8, this will be even worse without the right gear.
Best combination is a 3.5 inch lift kit and a half inch spacer with 37 x 13.5 r17 tires, it's amazing and you do not have to regear the 4.10 gearing ,only time you have to change the gearing with the 4.10 is if you get 40 inch tires or up, anyting less ,4.10 gearing is perfect and a lot of power ,I have it on my 2019 4-door Jeep Rubicon
JKU Rubicon, Rock Krawler 2.5" Flex lift, with 35x12.5x17 BFG. The Jeep is a 6 speed manual and still have the factory 4.11 gears.
Do you have spacers? If not, do you have any problems with rubbing? I've had 1in spacers for my 35x12.5x17 for a year, but just moved to Germany and my tires stick out past my flares--doesn't pass German law/inspection. I'm trying to find a cheap way to make this work and am trying to find input. Thanks!
I do not use spacers on my wheels. The rims are: Trail Master TM210 Wheel 17x9
I have a 2018 JL rubicon unl. with 33s and 4.10 gearing. Next will be a compressor, then a 3.5" terrraflex lift and 35's.
Very informative, thank you.
Great explanation! Definitely helps the 33s vs 35s debate.
Definitely helps a bit! I'm glad you like the video! Which do you prefer? -Brian
Totally agree. I am currently working on my set up. 285/75/17 Nitto on stock wheels with a 2" AEV lift/leveling kit and flat fenders.
would that setup work without the lift? I just swapped out the fenders and looks like it would work?
It might. The Nitto is supposed to measure out at 33.8". The 2" lift should give a little breathing room and maybe a little more articulation.
Considering 285/70R/17 ko2s on stock height & wheels. Suggestions?
Thanks for the info I’ll be sticking with 33s! Until I can afford the gears axels and lift!
Glad we could help! Nothing wrong with 33s at all, better fuel mileage that way😉 -Zach
It is a daily driver and I drive about 60 miles one way so mileage counts some!
really informative video. it answered a lot of questions i currently had.
I am glad to hear it Mario! That was our goal with this and while there still be more options for tires and gearing out there I think this really touches on the majority of discussions. Which tires are you running, or looking to get for your rig? -Brian
Im running 40's on RokJok 60 Axles (front & rear) with 6" Rubicon Express lift with Coil Over conversion. Had to re-gear to 5.38 but the drive is fantastic!
Good lord that is high, that means if it Snows it's going to get you first, Lolol
I'm perfectly happy with my 33's on 17x9's 🤷♂️. Perfect daily setup imo.
I'm running 35 s on a 4 in lift on wrangler X ,it aloud me to Ford a creek that had flooded the road, my previous grand Cherokee would have been flooded , I only had 18s on it . There was only one way I could get to work. Jeep life forever
Great informative video !
For me it is a matter of skill/fun. I could throw 37"+ tires on my jeep, but then I am just idling down a rough road for hours on end. With 33' tires I have enough clearance to go almost anywhere, but skill and knowing my jeep becomes a factor too, requiring me to be engaged and think about where my line should be. (That is also why I have a manual transmission, but that's another discussion)
Would that 33" combo work with a stock JK suspension?
IMO 31's-33's r good for those who like the look and off road a bit but also need 2 commute often in their jeep 35's-37's and above r for extreme off roaders and aren't gonna commute with their jeep

Great video! I'm purchasing a new jk 2 door & am going after a lcg look I saw on a Jeep concept vehicle, with 37s, a high top fender & just a 2 inch lift. But I'll start out with just the fenders (made by Notch I believe) and 35" Goodyear MTRs.
Jarret, that sounds like a solid start for your build. The 35s will still be intense and do the job off-road. And later on the upgrade will be even more fun! Let me know how it goes and thanks for watching! -Brian
I have BFG TA KO2 305 65 R18 for my Sahara with 2 inch lift. I think this is possibly the best ever tire for wrangler. They are almost 34 inches and no loss power at all so no need to change gear ratio. These are snow flake winter, all weather tires so no issues if you live up north.
Could you post some photos of your jeep, im thinking about the same configuration with stick wheels 18,
I can save you time, no need to watch this video...If you cant afford things like axle trusses, long arm lift kits, and regearing stay with a 33" tire and dont wheel it too hard ....done.
HAHA, Amen brother. Can you please make this into a 15 sec KZhead vid for the non reading crowd!!!
meh long arms are overrated
said the T-rex
Define too hard lol
Read enough forums @bdd1469? You dont need any of that to run a 35 on a JK except for gearing if your rocking a JK Sport. I run a 35" tire and wheel it hard with zero issues. Stop spreading false information.
I just lifted my 2dr JK with a 3.5 inch Rough Country kit and I have 33 inch tires. I am admittedly not a trail guy and my jeep is my daily driver. But I just wanted that extra oompfh. Lol. The 33's do look a little small now compared to before so I may go to 35's but since it's my daily driver I am more interested in a more decent smooth ride. Probably not the set up or lift some would want or use but for me it is perfect and I love it and everything is working great and my ride is way smoother than before.
Great video. I have a 2012 Wrangler, 4 inch lift, just upgraded from 35 Toyo ATs to 37 Cooper MTs, stock 3.73 gears are just a little sluggish, still does 70mph at 4k and the 3.6l has plenty of power to push them. But I will regear to 4.56 for full range both on and off road.
Since when does the 3.6 have plenty of power? It has about the same power as a Toyota corolla.
Thanks. Wow. 8 minutes circling back and 3 minutes making a second point.
for offroading and not aesthetics, i would go for skinny 33's, this will outperform any large-wide 35's-37's
Just bought a used ‘14 jk sport with some super skinny 33’s. It doesn’t look right to me but preforms awesome on the trail.. as a noobie, can you explain a little why the skinny 33’s out preform the 35’s?
Great vid bro.
As always great informative video. How much could I expect to pay on re-gearing my 2014 JK Rubicon to properly run 37's and what gear ratio should I choose? It's my daily driver but also a weekend warrior. I'm curently on a 3.5 xfactor rock krawler with 35 Nitto Grapplers. Thanx in advance for your reply!!!
Okay, I'm convinced that I need '40's' ....................... and that's just for the Honda Odyssey !
A buddy of mine had 31s on his Kia sportage. Thing looked like a monster truck with those on it. Lol It only lasted a couple of years. Everything broke.
The log was turned on its side when you drove over it with the 37s.... The 33 would have cleared it as well if it was laying the same way
When a business will be less than straight forward and honest in their video, can you really trust them to be honest when you buy products from them? Deceptive marketing makes me really wonder what else they will be deceptive about.
@@Daveinet Don't get to bent out of shape...they were just trying to prove a point.
@@xbpbat21x you can't prove a point when you're misleading the public. That's called lying, anyway you look at it
@@ronaldledgerton878 To me it's clear that he's explaining the concept of "tire clearance" which is basically what he said when he started. I don't see anywhere that he's trying to sell anyone on 37" tires or that he is trying to say that 37" tires give you "X" amount of clearance over a 35". Maybe if he would have taken out a rule and said "there is exactly this amount of clearance with a 37" tire" it would be misleading.
The knot on the log was facing upwards. They don't have any reason to lie about the height because everyone knows 37's are taller than 33's.
Thank you for this video. Very informative.
Thanks for watching! -Zach
One of the most informative videos on KZhead for new Jeepers! Thanks
Thanks for watching! -Zach
I accidently found out that having the tyre fill the wheel well is not necessarily the best thing to do. I have room for 37s with ease. However, I run 35 inch tyres to allow for more wheel stuff into the wheel well. The 37s looked much better. But it is not all about looks. The notably smaller tyres do have some advantages going over super uneven terrain like very rocky terrain. It was all a mistake I found this out. I had 37 inch tyres for five years and it was time to replace the tyres. The shop was out of 37 inch tyres so I opted to get the 35 inch tyres because I was on the spare and had five plugs on another one that was leaking. I was disappointed in the empty wheel well look, but when I went off road there were some advantages. The Jeep did hit a few more rocks with the axles, but not a lot more. But the articulation without rubbing was much better.
Just bought 2017 rubicon. Thinking 37s with 4" lift.
Do I can go 4 inch lift and 37 tire be ok all not?
Sunny Johal that’s a great combo lol that what I’m going to do you should update on how you like that setup
2010 3.8L manual tranny, 35" tires, 4" lift, 5.13 gears, grizzly lockers, yukon D30 axels, runs great
Excellent video. Thanks LIKE
all terain 33's vs mud tire 37's... and where were the 35's on the trail? meh
It would be cool to know what the recommended gear ratio for the various tires sizes would be, as well as the other factors you need to deal with, such as drive shaft length requirements, lift requirements, back spacing and fender clearance....etc.
rogue109 they have a chart somewhere online that will give you a good idea on what gearing you need for the tire size and transmission and engine you have. As far as drive shaft length I'm pretty sure once you go above a 3.5" lift then it becomes a concern along with many other components on the Jeep. I'm running 35s and 4.88 gears only because I wanted to be able to go to 37s later. At 70 mph I'm at 3000 rpm. Kind of high but I'm still getting 16-19 mph.
rogue109 I forgot to add that wheel back spacing for 35s and up should be no less than 3.75. As far as lift vs tire size. 2.5" you can run 35s all day just make sure you install the appropriate bump stops to prohibit any rubbing. 37s and up I would not run anything less than a 3.5" lift with proper bump stops and trimming the pinch weld in the rear wheel well. If you do run 35s or 37s and have a Dana 30 then there is possibility of bending the C's and axel it you plan on taking it off road a lot. Truss and gussets fix that problem.
Thanks man! Good info.
Rouge, If you like me your Jeep is on pavement most all week and weekends its play time, so unless your building a "hard core rock crawler" here is the formula you need to use. But first you will need to know the factory "OEM" gear ratio, "original" tire size.... that information can be found on your build sheet or you can request a "copy" of your build sheet online at the Jeep site... link is below - takes about 2-3 days to get a response...... formula is (new tire size multiply by factory gear ratio divide by factory tire size)..... Example---> my grand cherokee WJ came with metric tires but metric can be converted to inches. say i want to go to a 35" tire the formula is 35 multiplied by 3.73 factory gear ratio - divide by 29.1" factory tire = gear ratio.... so in my case the formula looks like this.... ( 35 X 3.73 / 29.1 = 4.48 ) so I would need 4.48 gears or as close as I can get..... this will keep your torque curve the same, shift points and speedo close to the factory setup as possible. (drive-ability) just give Jeep the make, model, year and VIN number. jeep is now owned by FIAT so the more info you give them will avoid (confusion) them looking in the FIAT database. Just request a "copy of the build sheet" at Jeep customer service-----> www.jeep.com/webselfservice/jeep/EmailPage.html?appStr=wccs&titleStr=Contact+Jeep&familyStr=brand&franchise=J&actionURL=%252Fwccs%252Fbrand_forms%252Fus%252Fwebform.jsp&promotion=null&category=U
My tires are metric, but they are 31.5" I believe, or quite close to that and I have 4:10 gears (I specified this when I ordered the Jeep the options were 3:83's or 4:10's). So using your formula that comes out to 4:03 for my stock setup. I'd like to run 35" tires, so like you I guess I'd need 4:48 (which I'm not sure exists, so something close to that I guess). Thanks so much for the formula and the links and stuff, that's really helpful! From this info I was searching for gear ratios and found this handy chart that seems to go along quite well with your formula: www.morris4x4center.com/jeep-tires/tire-gear-ratio-chart.htm
I run 33's 4,10 gears. core 44 rear axle w air lockers. stock 35 front axle for now.. works well
Just put 295/70 R18 on our '18 4drJKU, little bit of rub on tight turns, still have factory fenders on as well. Have the standard gears as we pull a small full size camper. We like the factory wheels, so wanted to keep them. Not sure if we need to change gearing.
'this obstactle we found on the trail' clean sawed wood lol
if its a maintained one, thats normal.
🤣🤣
If you place it, then walk in a circle, it becomes "found".
RIPP Superchargers will fix that power problem easily.
I was thinking Magnusson supercharger.
Great vid. I am running 33 10.50 15. Gives me more digging on highway and street snow and I can air down more than 17 or 18 rims. This is on a YJ with a 2.5l engine. Did have to re gear. One thing you might wish to mention is height gain. 37 only gives you 2" on axle over 33. Not much compared to the other drawbacks. Like steering and suspension wear.
Love these tires ! Sometimes hard to find .
really helpful!
I want the look and the ability to trail it once or twice a year - the easy stuff, lol. I will do lift and 2" lift and 33s.
Why not a 3inch lift? I'm in the same boat. Was thinking a 2.5, but the 3 or 4 inch RC lift kits are pretty affordable. Thoughts?
Portal's. 'Nuff said.
$20,000 is a lot.
Great video! I was running 33s with a 2 1/2 lift for dune bashing when we lived in Dubai, but now back in the states, I think you just sold me on at least 35s. (Or 33s and a good winch and skid plates ;-). )
Don't forget about 34's either! A 305/70R17 or a 285/75R17 could work pretty well for you too! -Zach
While I drive a Gladiator for that the Falkens that come are Heavy even at 33. I can safely move up to a 35 and lose weight w/ any other tire. Though the change in wheels is a whole diff story. I think moving to 35's and above are good if you also plan on tuning up for a little bit more power.
33s are the best size for all around. It has certainly gotten me down pretty much any 4wheeler or quad trail. Plus I still get great gas mileage. Which is great because it is also my daily driver. That being said I can certainly see how hardcore offroaders need lifts and bigger tires. What kills me is when I see the jeeps I do all done up yet I know have never even been off pavement. SOBs 285/75/ duratracs
35" for me :)
I run 37" KM2s on my 2013 JKU with 5:13 gears. My axle tubes are sleeved and the Cs are gusseted. I have already bent my Dana 30 tubes as I'm preparing to move up to one ton axles and 40+ inch tires. If you have a stock drive train and you wheel at all, you'll soon have issues with 37s wreaking havoc on u joints, wheel bearings, ball joints, steering components, etc. But that's why we love our sport, gotta pay to play
I'm running 33's on a Teraflex leveling kit and I have done some minor wheeling and it has been fine so far , I'm going to be going to a more advanced trail this summer but I really can't upgrade to a 35 because I don't want to spend the money on regearing and it is my daily driver.
Dana 30 front axle, 33" Max, or stay off the skinny pedal on the trail, or you'll be changing front axle joints on the trail. 20 years experience in a jeep club tells me so.
you should also consider, my 2 door, cause of the shorter wheel base bottoms out less w/smaller tires than the wife's soccer limo 4 door w/larger tires, yes gentleman, weather I drive or she does, lol
just to be xtra clear on this debate so you know my opinion, gonna build, wanna build, buy older if possible, I've owned jeeps my whole life, back when nobody wanted a jeep cause they were crap, my 04 tj is the best I have ever owned, Best off road, Best built, my wife's 14 unlimited, ? only good part is the 6 speed manual, the rest is poorly made and I hate to work on it, BUT, it is an absolute highway star, goes faster than any wrangler I've ever driven, w/o a doubt, it will for 100 m.p.h. ALL day long
I disagree, the Dana 30 front could for sure withstand 35's when it comes to medium offroading. Aslong as your not bouncing off boulders, its fine. Just my experience though. Cheers.
I'm looking at an 05 Rubicon. 35s Ok on the Dana 44s without regearing?
Matt Lee doesn't matter which axle you have, 35s are gonna require a regear unless you want your jeep to feel like it has no power and it will get insanely terrible gas mileage. Probably want to go to 4.88s or even lower gear ratios like 5.13s.
33 are just as good as 35 I have a 4 inch Skyjacker Lift sitting on 33s mud tires Firestone destination you should see the knobs on this tire
..looks is another thing..yeah, it's superficial but there's a lot of difference there...the only 'girlie mon' tires are the stock ones and they even don't do that bad off road...
Yeah sure, a 33" tire is as good as a 35" tire, just like a 5" dick is as good as a 7" dick.
ratio from 33:35 is much different that 5:7... just saying.
I find it inconceivable that anyone would say that when common sense and common knowledge will tell you that the bigger the tire the better the off-road experience will be. The difference is gradual as you go up but it is still there. Thus a 33 is not just as good as a 35. That is pure nonsense. Imagine some 66 inch tires. Are you 33's just as good as those? With those at the right air pressure you wouldn't even know that log was there. And per the point of the video you could clear good sized boulders and stumps. I suspect you have not compared with actual 35's on your rig.
great info!
I have 33s with a 4 inch ome lift looks good and very good off-road
How big can I go without it messing with my mpg or having to re gear?
Even with 33's your mpg will be worse than stock. With 33's, you won't need to re-gear, although I would still recommend it as the stock gears aren't that great. 35's, you'll should def. re-gear imo.
Re-gear is life when on 37's
JEEPARMY USA I'm on 37s with 3.73s and it's not bad honestly lol.
CodyyyAndAdammm People do it man.
mruss R when you switch to 37s go for the 5.13 gears trust me you'll be happier.
JEEPARMY USA awesome Vids jeep army
What's re-gearing? I'm thinking about buying a jk
Just for the record. I have a 2012 4door jk.4.5 in lift with 37 x 13.50 x 17. 240.000miles. 200k of which have had the kit and tires. To be honest unless you have something to compare it to , you might not notice anything. My gears are 3 something . Been off road in Colorado and Moab and such. Not trying to break anything. Held up pretty good. Ball joints went at 180k. Don't let people talk you out of going big. If it makes you happy go for it. It was worth it . Lots of fun.
