Compare the stock photo with the "after" photo. The Bushwacker cut-out fender flares open up about two inches of extra wiggle room all the way around. In addition to the wheel clearance around their circumference, the Bushwacker flares add about two inches of width. This added width goes a long way to contain mud and rocks flung from aggressive knobbies. The extra width helps avoid unpleasant conversations with peace officers, too.
