The largest tires for a Jeep Wrangler are the largest size that can be fitted on a stock vehicle. This means no modifications are needed to fit these tires, and it’s possible to install them with just an air compressor or power inflator. In this article, we will discuss what the largest tires you can put on a stock jeep wrangler are, why larger tires are beneficial for off-road driving, and the main factors to take into consideration when choosing tire sizes for your Jeep Wrangler.
How big can you go with tires on a stock Jeep Wrangler? It turns out the largest tires that will fit are 37 inches. This is an incredible feat, and was accomplished by modifying the suspension. The largest size tire available for purchase in North America is 37×13.50R17LT Goodyear DuraTracs mounted on 17×8 American Racing Wheels (with backspacing of 7/16).
What are the biggest tires you can fit on a stock Jeep Wrangler?
The largest tires you can fit on a stock Jeep Wrangler are the 37’s. This is the largest tire size that will still allow you to drive without modifications. A common modification done by off-roaders is changing their suspension system so they can run larger wheel sizes which would be advantageous for them, such as running 40″ tires and larger, but these modifications would be needed to fit larger tires on a stock Jeep Wrangler.

The main factors to consider when choosing a tire size
There are factors to take into consideration when deciding on tire sizes. These include but are not limited to:
- Year Model of your Jeep
- Suspension Setup
- Backspacing
- Centre of Gravity
- Intended Application
What modifications could be done to increase performance when using bigger tires
If your largest tire size is 37″ then you can still run without modification, but at any larger than that and a suspension system with rubber bushings will need to be installed in order for the tires not to rub against the fenders of the jeep. You may also want to look into running higher-quality tires that are made from a tougher material to withstand the wear and tear of off-road driving.
If you want to run larger tires, then you may need a suspension lift in order for the largest tire size that can be used without modification. A common modification done by off-roaders is changing their suspension system so they can run larger wheel sizes which would be advantageous for them, such as running 40″ tires and larger. Rubber bushings may also need to be installed in order for the largest tire size that can be used without modification not to rub against the fenders of your jeep.
Conclusion
The largest tires you can fit on a stock Jeep Wrangler are the 37’s. These will not be able to utilize all of your jeep engine power and may result in damage if run for too long without modification (such as suspension lifts). Therefore, smaller 35” tires are preferable. Some benefits of running larger tire sizes are that they will last longer than smaller ones because off-road driving tends to wear them out faster than a passenger car.
