Factory sizes for every 2026 trim, what fits without a lift, how low owners air down, and what JL owners report about their tires.
Picks come from counted owner reports and manufacturer data. We may earn a commission from links on this page; it never changes the ranking. Read our policy.
Everything here comes from Jeep’s own spec sheet and press releases, and from counted reports by Wrangler JL owners on JLwranglerforums.com. See how we research.
| Trim | Factory tire | Axle ratio |
|---|---|---|
| Sport | P245/75R17 Nexen Roadian HTX2 or Roadian ATX (about 31.5 in.) | 3.45 |
| Sahara | P255/70R18 Bridgestone Dueler H/T 685 or General Grabber AT Sport (about 32 in.) | 3.45 |
| Rubicon, Willys | LT285/70R17C BFGoodrich KO2 (about 33 in.) | 4.10 (4.88 optional on the 3.6-liter Rubicon) |
| Xtreme 35 package, Moab 392 | LT315/70R17C BFGoodrich KO2 (about 35 in.) | 4.56 |
When Jeep launched its 35-inch package for the Rubicon in 2021, it came with a 1.5-inch factory lift and 4.56 axles. Ground clearance goes from 10.8 inches on the 33-inch Rubicon to 12.9 inches on a 4-door with 35s. If you fit 35s yourself, see regearing for bigger tires.
| What owners report | Owners |
|---|---|
| No rubbing | 15 |
| Slight rub on the fender liners at full flex | 5 |
| Clear rubbing off-road | 4 |
| Didn’t say | 13 |
Most of the rubbing owners describe is on the plastic fender liners, usually at full flex. Four of the owners with no rubbing say they flexed fully or with the sway bar disconnected. Factory wheels don’t guarantee a clean fit: three of the four who rubbed clearly were on factory wheels, and one owner’s factory wheels touched the sway bar and lower control arm until the owner switched to −12 offset wheels. The fixes owners name are bump-stop extensions with half-inch spacers, a 1.5-inch lift, and wheels with a different offset.
| Size (about) | Owners on stock suspension | What they report |
|---|---|---|
| 285/70R17 (33 in.) | 9 | 4 no rubbing, 2 rub the front bumper plastics at full lock, 1 rubbed until a fender extension came off, 2 don’t say |
| 285/75R17 (34 in.) | 5 | 3 no rubbing, 1 rubs at full lock (fixed by removing the fender-to-bumper connectors), 1 rubs the rear fender off-road |
| 295/70R17 (33 in.) | 1 | Doesn’t say |
On bigger tires, check the spare too. Five owners report it rubbing the bumper or tailgate hardware, or not fitting the carrier, and two say it fit as is. Compare any size with your current one in our tire size calculator, or see what each step up changes in 33s vs 35s vs 37s.
| Lowest pressure owners run off-road | Owners |
|---|---|
| 10 psi or lower | 6 |
| 11–14 psi | 8 |
| 15–19 psi | 7 |
| 20–25 psi | 4 |
| Above 25 psi | 1 |
Owners who go to 10 psi or lower mostly name sand, snow or rocks, and two of those six run beadlocks or a bead-retention device. One owner broke the beads at 6 psi in snow, and one burped air at 15 psi in a rock garden. Two on factory wheels report no trouble at about 12 psi. Read our full guide to airing down.
The Rubicon, Willys and 35-inch packages come on BFGoodrich KO2s, and wet roads are what JL owners argue about. From 19 owner reports Of 17 who describe it, 8 say it’s fine in the rain, 5 say it slides, and 4 call it acceptable with limits. One owner reports 47,000 miles without a cut.
Quietest in JL owner reports
Who it’s for
JL owners replacing their factory tires who want a quiet all-terrain with a severe-snow rating.
Who should skip it
Owners who want a light tire: one JL owner calls it very heavy. No JL owner in our log has worn out a set yet.
Toyo’s Open Country A/T III has 4 JL owners in our log: 3 praise the ride, and one finds it slightly louder than the KO2. These are small samples, so see all 12 tires, counted across every vehicle, in best all-terrain tires and the all-terrain tire comparison.
