Will 31-inch tires fit a Jeep YJ with a 2-inch lift?
Fitment answer · Updated October 27, 2026
Short answer
Yes, easily. A 2-inch YJ lift has room for 31s (often 31x10.50R15), and many owners run them with minimal changes. Check wheel backspacing and steering wear.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
What you usually need
- A 2-inch spring lift or shackles, with matched shocks.
- Stock-style wheels usually work; check backspacing on aftermarket wheels.
- A quick alignment check after install.
Regearing
31s on a YJ usually work on stock gears, though 3.07 trucks can feel slow. Compare ratios in the Tire & Gear Calculator before you buy gears.
