Will 37-inch tires fit a Jeep Cherokee XJ?
Fitment answer · Updated October 27, 2026
Short answer
Only as a serious build. XJs running 37s usually have 6 inches or more of lift, cut fenders, upgraded axles and steering, and deep gears. It is not a bolt-on project.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
What you usually need
- A 6-inch or taller long-arm lift.
- Cut fenders or flares and bump stops.
- Upgraded axles, steering and gears.
Regearing
37s on an XJ typically need 5.13 or deeper gears and stronger axles. Compare ratios in the Tire & Gear Calculator before you buy gears.
