I was running Toyo Open Country 305-65-18s and had to cut the skid plate. After the 3" all around lift( I don't like leveling kits), I put 1/4" spacers on the front to clear the a-arm. but at 70 mph the truck would shake. So I took them off and really only rubbed if I was trying to park on a curb or turning too sharp. Love the BFG TA/KOs, great choice bro! Never had a prob with the sensors either.
