Here are the facts: 9 months ago I had 4 new tires put on my car. I drive 80 miles a day 4 days a week. (just to give an idea of how much wear the tires have had) Today I am driving to work and I run over something. 20 miles later my front right tire blows. I pull over and look at it - it is shreded. A total mess. When I ran over whatever I ran over I got the distinct impression that both my front right and my rear right tires hit the object. I looked at my rear right tire and it looks fine. Here are the questions: I have heard people recomend that you always replace tires in pairs. I am having a hard time stomaching that I have to replace both my front left (which didn't hit anything) and my front right tire. Is there anyone here that would actually say to me that I can get away with replacing only one tire? About that rear right tire. I can't see anything wrong with it. Is there anyone that wouldn't trust it? Is there anything wrong with asking the shop to replace the rear right tire but to move it to the front of the car? In other words what is now the front left tire wouldn't be replaced, but it would be switched to the rear right. Would this be bad?
