i wouldn't go in calm like nothing happened, be stern. they are a dealership and this type of stuff isn't supposed to happen. there is a such thing as professionalism.
yes, the mechanic or whoever is supposed to check the car before they released it should be fired. they didn't do their job and it could have resulted in an accident. When you're dealing with 3-5 thousand pounds of metal that can travel at a high rate of speed, "oops" doesn't cut it. Do you think that if their insurance company found out about this that they wouldn't be a little concerned?
they should replace all the studs. not just the visibly damaged studs but all of them. there is no telling what unseen damage might have been done to the "good" studs. They will probably also inspect the area if anything else was damaged. They should also offer you a substantial discount (not the 10% - 15% that dealerships mail out every so often, at least 20%) on future maintenance. You did spend extra time, gas, and money to deal with their mistake. I would not expect a new set of tires, I would hardly expect a single new tire.
So far they don't sound shady, so I think that they'll be fair as long as you don't go in there and start demanding a new car every 2 years with free maintenance for life
