Will 31-inch tires fit a stock Jeep Cherokee XJ?
Fitment answer · Updated October 27, 2026
Short answer
Often yes, with some rubbing. Many XJ owners run a 31-inch tire (often 235/75R15 or 245/75R16 class) on stock suspension, but expect contact at full lock or flex, especially on worn springs. A small 1.5 to 2-inch lift or a little trimming usually cures it.

What to check
- True tire size: "31-inch" tires vary by brand; a 30.5 can clear where a full 31×10.50 rubs.
- Wheel backspacing: aggressive offsets push the tire into the fenders.
- Sagging rear leaf springs are common on older XJs and reduce clearance.
Regearing
31s are a modest step; most XJs drive fine on factory gears, though 3.07 or 3.55 trucks feel softer. Check the calculator. Compare ratios in the Tire & Gear Calculator before you buy gears.
