Biggest Tire You Can Fit on a Stock Jeep Wrangler

Jeep Wrangler is one of the most prominent SUVs in America. People love Jeep for its relatively compact size, high off-road capabilities, and unique outlook. Wrangler is valued for its classic design, the possibility to remove doors and roofs, and a wide specter of customization.

The most common upgrade for Jeep Wrangler is the installation of bigger tires either for the aesthetic side or more for offroading features.

Many Wrangler owners wonder: what is the biggest tire size that can be mounted on a stock Jeep Wrangler?

Considering that Jeep has many trims, there is no universal answer. Most Wranglers come off the factory line with stock tire sizes from 29 to 32 inches.

A 33-inch tire can go on a Wrangler without rubbing or requiring any modifications to the suspension.

While browsing various Jeep forums, we`ve noticed that some devoted Wrangler enthusiasts managed to install 34 and 35-inch tires on their stock Jeeps. Such sizes fit wheel wells and don’t cause any fenders rubbing.

Some owners of the stock Wranglers went even further and mounted a 37-inch tire!

However, only unmodified 2022 Jeep Wrangler Unlimited Rubicon 392, 2020-2022 Unlimited Rubicon, Unlimited Rubicon 392,2018 Unlimited Rubicon, and Unlimited Sport are capable of accommodating such a tire size.

We`ve also created valuable tables that list the biggest tire sizes for each year. As I have mentioned before, these tire sizes from the table do not cause rubbing or require cutting the fenders or changing the factory suspension.
