Will 35-inch tires fit a Jeep Gladiator JT?
Fitment answer · Updated October 23, 2026
Short answer
It depends on the trim. Rubicon and Mojave Gladiators have more factory clearance, and many owners fit 35s on them with modest changes. On Sport and Overland trucks, plan on a lift (often around 2.5 inches), wheels with the right backspacing and bump stop changes.
What you usually need
- On Sport or Overland: a lift, often in the 2–2.5 inch range or more.
- Wheels with less backspacing than stock so the tire clears the control arms at full lock.
- Bump stop extensions sized to your setup, and an alignment after install.
Regearing
The Gladiator is long and heavy, so 35s are felt more than on a Wrangler, especially when towing or loaded. Many owners regear for 35s. Compare ratios in the calculator before deciding.
Other caveats
- Heavier tires and wheels count against payload; check the Load Range against how you load the bed.
- Fitting a 35-inch spare under the bed may need a different mount or spare location.
- Recalibrate the speedometer.
