You obviously didn't look at my profile picture or signature :gy: That by itself won't make a mess of the paint unless you're driving on rocky roads. I'm running 37" Toyo MT's that stick out 3" past the fender and I don't have any issues. Sure there's a few rock chips on the underside of each rocker panel, but no more than a completely stock truck would have. The lugs on Toyo MT's or Trail Grapplers are spaced so far apart that they generally don't pick up rocks. I have far more chips on my front bumper from vehicles in front of me than I do anywhere else on the truck.
