Will 38-inch tires fit a JL Wrangler 4xe?
Fitment answer · Updated October 27, 2026
Short answer
Only with a serious build. 38s on a JL Wrangler 4xe need a 3.5-inch-plus lift, high-clearance fenders, 5.38 gears and steering/axle upgrades, and the 4xe’s battery weight adds stress. Not a daily-driver setup.
Shop the gear for this build ↓ Tires, deflators and a compressor picked for this setup.
