There are several model variations of the Jeep Wrangler. If you want to know the size of the stock tires, it pays to know what specific model you’re driving.

You may refer to this guide to learn about the stock tire sizes on the Jeep Wrangler JL models from 2018 to present.

Due to the slight differences in the stock tires, you must keep those differences in mind when selecting the correct size for replacement tires. This guide will help you pick the right set of tires without compromising performance and maneuverability. It is especially helpful if you want to get bigger tires without modifications or using a lift kit.

Will 33-inch tires fit the Jeep Wrangler JL?

The Jeep Wrangler JL Rubicon is equipped with 33-inch factory tires. Therefore, a 33-inch tire is a suitable replacement on the Rubicon, especially if you choose not to upgrade to a wider tire and wheel combination.

Another option to fit 33-inch tires with other Jeep Wrangler JL models with a stock tire size smaller than 33 inches would require slight modifications. One option is to replace the factory fender flares with a raised or high-top version. You can even find them in various colors to match your styling preferences for the color of your Jeep. The optional addition of wheel spacers would also help accommodate new and bigger tires. Since replacing the fender flares won’t affect the vehicle’s performance and handling, you could safely switch to 33-inch tires without major issues and impact on the ride performance.

Will 35-inch tires fit the Jeep Wrangler JL?

A 35-inch tire upgrade will fit and work seamlessly on the JL Rubicon model, whether for on- or off-road use. The JL Rubicon suspension can handle the stress of the 35-inch tires, although you must note that there could be minor rubbing on certain terrains.

If you intend to upgrade to 35-inch tires and use the Jeep Wrangler JL off-road, it is best to modify the Jeep with one- or two-inches lift. Lifting the vehicle will help you get away with major suspension modifications.

For other JL models like the Sport and Sahara, you will need aftermarket installation of raised fender flares on top of getting a lift. Certain Sport and Sahara models require up to three inches of lift and axle assembly upgrade to accommodate 35-inch tires for off-road use.

Will 37-inch tires fit the Jeep Wrangler JL?

If you want to upgrade your Jeep Wrangler JL into 37-inch tires, you are into a serious off-roading adventure. But will it fit on the Jeep Wrangler JL?

Yes, you can fit a 37-inch tire into any JL model, but it will require serious modifications. The most basic modification requirement is to use a lift kit. You need at least 2- to 3-inch lifts and properly allocated bump stops. The axle assembly is at its operational limit with these tire sizes. This is true with the Rubicon variant of the Jeep Wrangler JL.

For the Sport and Sahara models, you can fit 37-inch tires, but you must lift the vehicle and update with raised fender flares. If not, the bigger tire size could be a problem off-road.

How Big of Tires Can You Get for Jeep Wrangler JL?

The maximum tire size for the Jeep Wrangler JL model is 33 inches, for most JL models. However, several factors influence your decision when choosing the maximum tire size for the Jeep Wrangler JL.

Again, numerous factors like the year model, the suspension, body shape, and backspacing can factor into the maximum tire size choice.

Year Model

Each Jeep Wrangler JL model has varying specifications and factory rims and tires. Consider the manufacturer’s specifications and recommendations before choosing the maximum tire size.


Suspension is a crucial consideration when upgrading your Jeep Wrangler JL tires. The stock suspension limits the size of the tire you can choose for your vehicle, and you must make sure they are within the factory specifications. The components within the suspension system, such as shocks and springs, are designed for the stock tire size. A bigger tire would mean added stress on these components.


The backspacing dictates the maximum tire size for your Jeep Wrangler JL, if you want to replace the stock tires. It refers to the distance between the hub mounting surface of the wheel and the wheel’s inside edge. This measurement determines how far the wheel will stick out from the fender flares and whether the tires will rub against the body. Therefore, you are limited when upgrading the tire sizes by this measurement.

Center of Gravity

If you plan on taking your Jeep Wrangler JL off-road, it’s crucial to consider the center of gravity. The lower the vehicle is to the ground, the more stable it is. In addition, bigger tires equate to more height on the vehicle. You must consider how high you want your Jeep Wrangler JL to go, especially if you use it mostly for off-roading.


When upgrading to a new set of (bigger) tires on your Jeep Wrangler JL, it’s worth noting that every vehicle is different. There is no exact answer on the biggest tires you can upgrade to.

However, knowing the stock tire size on the Jeep Wrangler JL models give you an idea of your starting point and how big you can go. While bigger tires look good, and makes your Jeep Wrangler JL beefier, you should never compromise safety and handling for aesthetics.

This will ensure you can maintain its power and performance under any driving conditions.
