Will 35-inch tires fit a Jeep Gladiator Sport?
Fitment answer · Updated October 27, 2026
Short answer
With a small lift, yes. Most Gladiator Sport owners fit 35s with a 2 to 2.5-inch lift, low-backspacing wheels and bump stops. Regearing is common, especially if you tow or haul.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
