Will 37-inch tires fit a Jeep Gladiator Mojave?
Fitment answer · Updated October 27, 2026
Short answer
With a lift, yes. Mojave owners fitting 37s usually add around 2.5 to 3.5 inches of lift, bump stops sized for the tire and low-backspacing wheels, then regear.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
What you usually need
- A 2.5 to 3.5-inch lift made to work with the Mojave suspension.
- Bump stops sized for 37s.
- Wheels with about 4.5-inch backspacing or less, plus an alignment.
Regearing
With 37s on a Gladiator, 4.88 or 5.13 gears are common. Compare ratios in the Tire & Gear Calculator before you buy gears.
