If you intend to take your Jeep Wrangler off road, you must install bigger, taller tires. Because they are also much wider, these tires will not be enclosed by the stock fenders. They will actually jut out a bit, which may result in damage from road debris that is propelled upward by the edges of the tires. Jeep Wrangler fender flares are designed to overhang large off-road tires, which prevents damage on difficult trails. The sets we sell are designed for the Jeep Wrangler. They simply mount into the holes that were drilled at the factory. On occasion, Jeep owners may have to make a few minor modifications before they install our fender flares.
