Last time I tried to change my own tire I got stumped by the stupid decorative lug nut covers on my duallys. I could break them off, but no way I could figure out how to get them off intact. Unfortunately I don't see how they did it at the tire shop, though I noted they came back with several fewer in place than they went in with, so perhaps I was not alone in my difficulties. Pretty soon they will all be gone. I couldn't budge the lugs with a cross type wrench either, so getting the covers off didn't really help me. A 4 ft pipe helped pursuede them, but I worried about breaking one, so took it someone with an impact wrench. Doesn't bode well for a flat in the wild.
