Recently had new tires put on by the Big O in Arvada, CO on 64th and Indiana. They had done a bit of other work for us as well. Initially they were very helpful in every way. Now, 2 months (5000 miles) later when we brought the car back because 4 out of 5 lug nuts snapped off while driving down Floyd Hill on I-70 doing 75 mph with my wife and kids in the car, they want to charge me $488 to fix the damage!! The guy on the phone, I think his name was Adia, flat out said that they looked as though they were over tightened. They they looked different then other snapped off bolts he had seen. Then immediately tried back-tracking and explaining why it's impossible to over tighten the bolts. All I know is that they put the new tire on and 2 months (5000 miles) later its nearly comes off while driving with my family in the car. Guess it's time to get a lawyer!
