Jeep Wrangler Tire Size Chart
Quick answer: most 2018-and-newer Jeep Wrangler JL models use 245/75R17, 255/70R18, 255/75R17, 285/70R17, or 315/70R17 tires depending on trim and package. Sport and Sport S models are commonly 245/75R17, Sahara models commonly use 255/70R18, and Rubicon models commonly use 285/70R17. Always confirm the tire placard on the driver-side door jamb before ordering tires.
Jeep Wrangler Tire Size Chart By Trim
The chart below is a practical reference for common late-model Wrangler JL factory tire sizes. Jeep changes packages and special editions over time, so use this as a starting point and verify against the door placard, owner information, or a tire retailer’s vehicle lookup before buying.
| Wrangler trim or package | Common factory tire size | Approx. overall diameter | Typical wheel | Notes |
|---|---|---|---|---|
| Sport / Sport S | 245/75R17 | 31.5 in | 17 in | Common base JL size. Good baseline if you want an easy replacement without changing ride height. |
| Sahara / Sahara Altitude | 255/70R18 | 32.1 in | 18 in | Common Sahara road-focused size. Similar height to 255/75R17, but on an 18-inch wheel. |
| Moab / some Willys and special editions | 255/75R17 | 32.1 in | 17 in | Popular middle size. Often seen on appearance or off-road-oriented packages. |
| Rubicon | 285/70R17 | 32.7 in | 17 in | Common Rubicon size and the usual factory reference for a roughly 33-inch Wrangler tire. |
| Rubicon Xtreme Recon / High Tide / some 392 packages | 315/70R17 | 34.4 in | 17 in | Factory 35-inch-class size on specific packages. Do not assume this fits every stock Wrangler package. |
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.
Tire Load Ratings For Wrangler Sizes
Load index matters because Wrangler tires are used on a relatively heavy, boxy vehicle that may carry recovery gear, tools, roof racks, cargo, or a full-size spare. Use the load index listed for the exact tire you are buying, not just the size stamped on the sidewall.
| Load index | Pounds per tire | Kilograms per tire | Where you may see it |
|---|---|---|---|
| 112 | 2,469 lb | 1,120 kg | Some passenger-rated SUV tire listings |
| 113 | 2,535 lb | 1,150 kg | Common in 255/70R18 all-season/all-terrain options |
| 116 | 2,756 lb | 1,250 kg | XL-rated SUV tire listings |
| 118 | 2,910 lb | 1,320 kg | Light-truck all-terrain options |
| 121 | 3,197 lb | 1,450 kg | LT-rated tires often used for heavier-duty off-road setups |
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.

Source Notes
Factory-size references were checked against tire retailer vehicle lookups and Wrangler tire-size references, including Goodyear’s 2018 Wrangler tire-size lookup, TireSize.com’s Wrangler Unlimited listings, and RealTruck’s Wrangler tire size guide. These sources are useful cross-checks, but the tire placard on your Jeep is still the final reference for your vehicle.
