Thats what I would say, its about 3/4"-1" of additional "coverage" I would consider them more of a trim piece, but for stock or near stock wheels/tires they will probably give you enough to keep the sides of the truck clean.

Well guys, to be honest I don't really like the look of aftermarket flares so that is why I was thinking of going with the lariat style flares since they offer a little more coverage but arent huge. The only reason I am even looking into these is because I continue to get pulled over for my damn tires sticking out. :)
