Every tire shop I have ever been to uses impact guns to get the lugs off and on.I had my trooper in there once , but didn't have any get stripped , either I was lucky , or they knew to turn down the torque settings <img src="/forums/images/graemlins/smile.gif" alt="" /> I can tell you when I get my new rims and tires on , I am doing it myself , and no impact wrench , just by hand <img src="/forums/images/graemlins/kewl.gif" alt="" />
