Can You Fit 37-Inch Tires on a Jeep Gladiator?
37s are realistic on a Gladiator, but the answer changes by trim. Rubicon and Mojave provide the best starting geometry; non-Rubicon builds usually need more suspension, wheel and fender planning.

At a glance
Fitment by configuration
These are planning categories—not installation guarantees. The exact wheel and measured tire dimensions can move a build between outcomes.
Sport / Overland, stock
Insufficient all-condition clearance.
Sport / Overland, 2 in. lift
Fender and wheel package remain critical.
Rubicon / Mojave, stock
May street-fit; off-road compression needs verification.
Rubicon / Mojave, 2–3 in. lift
A documented, common target with suitable wheels.
Likely contact points
- Fender at full compression
- Inner liner
- Control arms with stock backspacing
- Spare-tire packaging
Before you order
- Plan bump-stop length with suspension travel
- Check steering at both locks
- Verify axle gearing for use case
- Account for the actual spare
