Will 37-inch tires fit a TJ Wrangler with a 6-inch lift?
Fitment answer · Updated October 27, 2026
Short answer
Yes, with some work. 37s fit a 6-inch TJ with flat or high-clearance fenders or light trimming, correct backspacing and bump stops. The stock Dana 30 front and steering are the weak links.
