This sort of thing demonstrates why I am afraid to let others (particularly in low-skill areas, like tires/oil change places) work on my car (even my "other" car). There is a torque spec for this, but I've seen oil change places tighten the *** out of this with nary a thought. I know a woman who got a new oil pan installed at a BMW shop because of overtightening at an oil change place (at the oil change place's expense). Same goes for wheels. I usually bring wheels in to a place I can trust not to scratch/bang up my rims, they mount the tire - I mount the wheel. I went to one place I liked in the city I used to live in where air tools were not permitted in the tire area (no air hose connections). Reason: They had to buy $hundreds of 1980's dollar rotors on a newish Jaguar whose lugs had been overtightened to the point of distorting the rotors.
One of my spare wheels has damage in the lug area because someone in the past snapped off a lug, which had to be drilled out. Bet it was "torqued" with an air tool!
