The guy there told me that it's Nevada State Law that if a car comes in with a flat, they have to replace all four. That really makes no sense to me!! But, since all the tires were getting pretty bald anyway (1/32" tread), and I was already planning on getting them replaced shortly, I went ahead and had him give me all four.
But I was thinking: Why would there be a law like that? Was the guy trying to con me? CostCo has an excellent reputation, so I was wondering if any of you have heard anything like that.
As for the service otherwise, no problems. I was out the door within an hour, four new tires ready to roll. (Still need to replace the spare, though.)
Is there really a law like that, or did the guy try to play me for a sucker?
