Damn that sucks. Sorry to hear that.
On my 94' 4Runner, I had 31" tires put on by America's Tire company and all was fine, so I thought, until I tried to take the rim off. These a$$holes thought they were part of a NASCAR pit crew, and probably put the lug nut in thier air gun and tried to go as fast as they could putting the lugs on. Three of the five lugs on one wheel were completely stripped, and had to be broken off to be taken off. And the worse thing about it, it was the brake drum on the back. So the differential had to be opened up, the axle had to be knocked out to get the drum off, and then the lugs could get replaced. I brought it back, and they tried to blame me and say I did it, since I was the one taking my own tire off. I demanded to talk to the manager, and raised my voice in front of all kinds of customers, and he told me he made a call to a auto shop down the street to have it done. And I got it repaired for free.
I will never bring any of my cars back to America's Tire company ever again.
I feel you pain bro.
