Will 37-inch tires fit a Jeep Gladiator Overland?
Fitment answer · Updated October 27, 2026
Short answer
Yes, with a real lift. 37s on a Gladiator Overland usually mean 3–3.5 inches of lift, high-clearance fenders, bump stops and low-backspacing wheels. The Overland's Dana 44 axles are fine, but payload, towing and braking take a hit.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
What you usually need
