This article will explain the fitment of 35” tires to a stock Jeep Wrangler and what you can expect in terms of clearance, articulation, and any additional modifications needed to make them function properly. So without any further ado – let’s find out what is required to make 35-inch tires fit on a stock Jeep Wrangler JK
Fitting 35” tires on a Jeep Wrangler JK with a stock suspension requires the following:
- Removal of splash guards
- Fit a Rear Spare Wheel Spacer/Extender
- Fit Wider Aftermarket Wheel Flairs
- Leave the front sway bar connected
So basically, yes it can be done but not without some additional modifications first. If your intention is to go off-road, it is highly recommended to fit a minimum of 2” lift to be able to disconnect the front sway bar to take advantage of the Wrangler’s legendary articulation. When flexing, the wheels will scrub heavily against the wheel arches and possibly rip off some plastic if you don’t take it slow. It won’t be a pleasant experience off-road – believe me!
If the modification is purely for aesthetic purposes and you don’t intend to do more than just a dirt country road and no wheeling difficult off-road trails, then you can definitely get away with 35’s, but you will be limited! Let’s look closer at the fitment options
Jeep Wrangler 35 Inch Tires, No Lift (FITMENT GUIDE)
I’m sure you’ll agree that larger tires simply look amazing and add an element of ruggedness to almost any 4WD, especially a Jeep JK! However, when going too big, you are somewhat restricted with a stock suspension on your Jeep especially if your intention is to do hard tracks regularly.
So let’s see what the largest tire size is for a stock Jeep Wrangler and still be able to take it off-road without additional mods.
The biggest diameter tire you can fit on a Jeep Wrangler with a stock suspension is 33 inches. The common 33-inch tire sizes are any of the following:
There are other factors to take into consideration when deciding on tire sizes. These include but are not limited to:
- Year model of your Jeep
- Wheel Clearance
- Wheel offset
Let’s take a deeper look into the pros and cons of fitting bigger wheels to your Jeep and what you need to take into consideration before you proceed with the tire upgrade.
Year Model of your Jeep
Well, every Jeep, like most car models, is built for a specific application and each has its own strengths and weaknesses. So what might be a relatively straightforward fit for one model will require some minor or even major modifications on another.
The Wrangler JK is produced stock with various tire sizes depending on the model Wrangler you buy Rubicon, Sahara, Sport, etc. The stock tire sizes are: 255/75R17 (32″x10″), 225/75R16 (29″x9″) and 255/70R18 (32″x10″). When it comes to the Rubicon, which was built for heavy-duty off-road applications in stock form, will easily be able to accommodate a bigger tire without much modification since the suspension setup is already primed for off-road use. In this case, we are referring to the JK specifically.
Wheel Clearance for 35” tires
If your intention is to run heavy off-road trails which will require maximum suspension articulation, then the 33” tire on a stock suspension will work much better. It’s still recommended to upgrade your suspension first to accommodate the bigger wheels and allow for maximum flex over big obstacles.
Hence, an upgraded suspension will allow you to not only increase your load carrying capabilities for Overlanding but also stiffen up the ride for better off-road stability.
Fitting 35’s however will require some additional work. There is enough clearance to drive on a flat road since there is enough clearance between the tire and the chassis/frame and other suspension components. The story isn’t so good for behind the front bumper. There you’ll be scrubbing and scraping all day when clearing off-road obstacles since the clearance is very minimal. On the rear it’s clear for everyday travel, however, once you flex the JK you risk ripping off a fender.
Watch them fit 35’s on a JL:
So the Rubicon comes stock with a 33-inch tire. This means you should be able to safely upgrade to a 35 tire inch without any dramas and still be well within the operational specs. Your speedo should still be reading fairly accurately. There are several Jeep Rubicon owners who fitted 315/70R17 tires and went “wheeling” disconnected with no rubbing or body scrub. Others claim to have fitted 35/12.5R17 which rubbed off-road without disconnecting the swaybar.
So as mentioned previously, it’s not only the wheel diameter that needs to be considered but also the wheel width, which is also affected by the offset of the rim. The backspacing comes into play again. The backspacing on stock JK wheels is 6.25″, which means that the mounting surface of the wheel is 6.25” from the rear lip of the wheel
So you could, and many have fitted 33-inch tires on a stock JK, again depending on what the intended use was for, but there could be scrubbing against the fenders and inner wheel arch. And disconnecting front sway bars most definitely results in body scrub.
SO if you want to fit a larger but not wider tire on the stock suspension and still have no issues off-road and achieve full flex without scrubbing you are pretty much limited to 255/80/17. This is basically the same width as the stock JK tire but with a higher sidewall. This will also give you increased ground clearance since your Jeep will be sitting higher off the ground and improved clearance on the diffs and lower hanging components.
The bottom line here, if you fit tires much wider than the 11” tire on stock wheels, your chances of making contact with your rear sway bar end link are high. Here fitting wheel spacers will rectify this issue.
The biggest tire you can fit on a stock Jeep Wrangler TJ is a 31×10.50. That is on a stock suspension and stock wheels and no other modifications. With this size, you can run comfortably off-road without causing any damage even during full articulation.
In the event there is somebody scrub at full lock, simply adding a few washers on the steering stops can rectify this.
If aesthetics is what you are after and have no intention of going off-road then you could squeeze up to 33 inches on the stock JK. However, you will not be able to venture off-road without a lift.

We know Jeeps are very versatile vehicles and the extent of your modifications runs as deep as your pocket allows. So basically you can get away with a lot with Wranglers since they are the perfect platform for modification and upgrades. It’s just how they were built. So if your intention is to wheel regularly and do tough tracks then we recommend a minimum 2”-2.5” lift if you plan to run 35’s. Alternatively, a set of aftermarket flairs will allow for the additional clearance when at full flex.
