Will 37-inch tires fit a Jeep TJ with a 2-inch lift?
Fitment answer · Updated October 27, 2026
Short answer
No for most builds. A 2-inch TJ is too short for 37s. Owners who run 37s usually lift 4 inches or more, cut or swap fenders, upgrade axles and regear. At 2 inches stick with 33s or carefully fitted 35s.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
What you usually need
- Much more lift than 2 inches for 37s, plus fender cuts or flat fenders.
- Stronger axles and steering; stock TJ parts take a beating on 37s.
- Wheels with the right backspacing and an alignment after install.
Regearing
37s on a TJ almost always need 4.88 or 5.13 gears. Compare ratios in the Tire & Gear Calculator before you buy gears.
