Jeep tire sizes

We cover 25 Jeep models across 59 factory fitments, spanning model years 1963 to 2024. The size that turns up most often on a Jeep is 235/75R15, followed by 255/75R17 and 31x10.50R15. Wheel diameters run from 15 to 22 inches, so the trim and wheel package matter as much as the model year.

Jeep does not stamp an approval code on tires the way Porsche and BMW do, so any tire in the right size that meets the load index and speed rating on the door placard is a legitimate replacement. Pick on wet braking, tread life and price instead.

Pick your model below to see the size for every year and trim, what it costs from budget to premium, and which tires are worth buying in that size. If you already know your size, search by size instead, and if you are not sure where to find it, our guide on reading a tire size shows exactly where the placard sits.

Jeep is Stellantis's off-road brand and the descendant of the wartime Willys, sold through AMC and then Chrysler. US volume has fallen from over 900,000 a year at its peak to above half a million, built around the Grand Cherokee, Wrangler, Compass and Gladiator. Its reputation rests on the Wrangler's solid axles and removable roof, and on the Trail Rated badge.

For tires Jeep is the most upsize-driven make on the site, because a large share of owners fit something bigger than the factory size on purpose.

Tires on a Jeep

Jeep stamps no approval code on its tires, so the placard specification is the whole requirement and there is no letter to match. What makes Jeep different is that the factory sizes are only the starting point: a Wrangler JL Sahara runs 255/75R17, a Rubicon comes on 285/70R17, and the Xtreme Recon package puts 35 inch tires on from the factory, while the aftermarket routinely goes to 33, 35 and 37 inch fitments on 17, 18 and 20 inch wheels. All Wrangler and Gladiator fitments are square, and crucially the spare is a full-size matching tire on the tailgate, which means an upsize is a purchase of five tires rather than four; buying four and leaving the original spare in place gives you a mismatched wheel that a four-wheel-drive system will not thank you for.

The Grand Cherokee is the volume model and behaves like a normal crossover, on 265/60R18 or 265/50R20 with 275/45R21 on Summit trims. Going up in tire size on any Jeep changes the effective gearing, the speedometer reading and often the fender clearance at full lock, and once you pass about 35 inches a regear is the usual accompaniment rather than an optional extra.

The models that matter

The Grand Cherokee is the volume model, on 265/60R18, 265/50R20 or 275/45R21. The Wrangler JL runs 255/75R17 on the Sahara and 285/70R17 on the Rubicon, with 33, 35 and 37 inch upsizes on 17, 18 and 20 inch wheels. The Gladiator uses 255/75R17 and 285/70R17 on the Rubicon.

The Compass takes 215/65R17 or 225/60R17, and the Renegade 215/60R17.

What owners find out later

Because the Wrangler and Gladiator carry a full-size matching spare, every tire upsize is a five-tire job, and this is the single most common budgeting mistake Jeep owners make. LT-rated tires such as LT285/70R17 need higher pressures than the placard's P-metric figures, and running an LT tire at a P-metric pressure gives a harsh ride and uneven center wear. Larger tires without a speedometer recalibration leave the odometer under-reading, which quietly stretches oil-change intervals and warranty mileage.

The heavy 35 and 37 inch tires also strain the tailgate hinges on a Wrangler, which is why reinforced spare carriers are a common accessory rather than a cosmetic one.
