Will 31-inch tires fit a stock TJ Wrangler?
Fitment answer · Updated October 27, 2026
Short answer
Usually yes. Many TJ owners run 31-inch tires (often 31×10.50R15 or 245/75R16) on stock suspension. Light rubbing at full flex is possible, especially with aggressive wheel offsets.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
What to check
- True tire size varies by brand.
- Wheel backspacing: aggressive offsets push the tire into the flares.
- Worn or sagging springs reduce clearance.
Regearing
31s are a modest step; most TJs drive fine on factory gears, though 3.07-geared trucks feel softer. Compare ratios in the Tire & Gear Calculator before you buy gears.
