Jeep Wrangler Tire Size Chart
Quick answer: Wrangler JL tire size depends on model year, trim, drivetrain, and package. For 2026, Goodyear lists 245/75R17 for Sport/Sport S, 255/70R18 for Sahara, 285/70R17 for standard Rubicon/Rubicon X/Willys, and 315/70R17 for selected Xtreme Recon packages. Its 2024 lookup also lists 20-inch tires on some 4xe trims. Check the driver-door placard or confirm by VIN before buying.
Selected Factory Sizes by Model Year
The table lists selected Goodyear fitment examples for 2024 and 2026 Wrangler JL models. It is not a complete year-by-year catalog. A trim name alone is not enough to identify a tire: drivetrain, 4xe configuration, package, and model year can change the fitment.

How To Read A Wrangler Tire Size
A size such as 285/70R17 has three important parts. The first number, 285, is section width in millimeters. The second number, 70, is the sidewall height as a percentage of that width. The final number, 17, is the wheel diameter in inches. A larger first number usually means a wider tire. A larger sidewall percentage usually means a taller tire if the width is similar.
That is why 255/70R18 and 255/75R17 are close in overall height even though they use different wheel diameters. The 18-inch Sahara tire has less sidewall, while the 17-inch tire has more sidewall.

Will A Larger Tire Fit A Stock Wrangler?
Many Wrangler owners move from a Sport or Sahara factory size to a Rubicon-style 285/70R17 tire, but fitment depends on wheel offset, suspension condition, trim, fender clearance, spare-tire carrier clearance, and how the Jeep is used. Street driving is not the same as turning and flexing off-road.
Before upsizing, check four areas:
- Steering clearance: turn the wheel fully left and right and check control-arm and sway-bar clearance.
- Fender clearance: the tire may clear on flat pavement but rub during suspension compression.
- Spare tire fit: the rear carrier, bumper, camera cover, and third brake light can limit larger spare tires.
- Speedometer accuracy: larger tires change effective gearing and speedometer readings unless recalibrated.
If the Jeep is a daily driver, stay conservative. If it sees trail use, measure at full steering lock and consider suspension travel, not just parked clearance.
What a Tire Load Index Means
A tire load index is a standardized code for a tire’s maximum reference load under its rated conditions; it is not the vehicle’s payload rating. Actual capacity depends on the exact tire and inflation pressure. Use the load/inflation data for the tire and never go below the size and load capacity specified on the vehicle placard.
| 112 | 2,469 lb per tire | 1,120 kg per tire |
|---|---|---|
| 113 | 2,535 lb per tire | 1,150 kg per tire |
| 116 | 2,756 lb per tire | 1,250 kg per tire |
| 118 | 2,910 lb per tire | 1,320 kg per tire |
| 121 | 3,197 lb per tire | 1,450 kg per tire |

Replacement Checklist Before Buying
- Read the driver-side door-jamb tire placard.
- Match the wheel diameter: 17-inch tires do not fit 18-inch wheels, and 18-inch tires do not fit 17-inch wheels.
- Check load index and speed rating against the tire placard and your use case.
- Compare the spare tire size, not just the four road tires.
- If you change diameter, plan for speedometer recalibration.
- If you tow, carry tools, or use a roof rack, be extra careful with load rating.
