I am thinking that the tire shop who did the work is the one who eats the bill on this. the reason being that I have been repairing vehicles for 25 years and the only way a lug stud gets damaged in the shop is if someone trys to remove it with an impact going the wrong way, basicly they over tightened it till it broke. Or they could have over tightend them while doing the reinstall. lug studs should be set as high as 100 ftlbs of torque depending on the type of wheel. its their baby now. </div></BLOCKQUOTE>

I doubt these studs were broke by overtightening. These are pretty hefty stud and lug assemblies. More likely they were cross threaded by the last person and when the tire guy took them off the seized up and then the gun broke em. Air guns make more power in reverse than in forward. But these studs dont just snap,it definately takes some effort. They should have told you there was a problem on the very first lug that was tight. Oh well thats just the way I see it.
