Will 37-inch tires fit a JL Wrangler with a 6-inch lift?
Fitment answer · Updated October 27, 2026
Short answer
Yes. A 6-inch JL clears 37s comfortably, usually even with stock fenders, as long as wheel backspacing and bump stops are set right. Many owners treat 6 inches as more lift than 37s strictly need.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
What you usually need
- Wheels with about 4.5–5-inch backspacing.
- Bump stops set so the tire clears at full stuff.
- Driveshaft, steering and brake line corrections that come with a 6-inch kit.
- An alignment after install.
Regearing
37s usually call for 4.88 gears, especially on 4-door or automatic JLs. Compare ratios in the Tire & Gear Calculator before you buy gears.
