I just bought 2 new tires for the rear but my main problem is that i know I have atleast 2 stripped studs. The lugnuts just spin and never get tight. How do I get these off without destroying my cobra r rims? Also how do I replace the studs? I think I'm just going to replace all the lugnuts with quality ones instead of the cheap ass ones on there(where do i get good ones?)Thanks.. I need to get this done soon since I need to get the tires on for inspection.
