Will 31-inch tires fit a Jeep JK with a 2-inch lift?
Fitment answer · Updated October 27, 2026
Short answer
Yes, with lots of room. A 2-inch JK fits 31s easily, though they can look small next to the lift. Most owners at this height run 33s or 35s; 31s make sense for mileage, winter tires or a mild daily driver.
