Lemme guess, they rub on the shocks and leaf springs, how do i know....well cuz i waz the one who cut up my perfectly good 17" rockkrawlers, i only have bout a 1/4' of runout on the worst wheel, I do drive it every day at bout 65 mph. i dont have them balenced but sombody told me to get this stuff called "equal"(you bust the bead and pour it in the tire), truckers use it to balence there tires. Now they have -1" BS, very stable now. Any questions, ask.
