Broken wheel rods where the lugnuts go?

[Yetti]

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.
