Discount Tire free replacement question?

Hi my 98 Trans am has Eagle GT tires from Discount Tire and only after 11000 miles they are riding bad. I got them balanced at discount tire but still they are kinda bad. They told me that the front 2 tires are worn out because my car has allignment or suspension problems. So I have the certificate for free replacement on these tires so wont they do anything about it? I checked with 2 mechanics they said that my cars suspension and all that are fine, so why is discount tire blaming my car? They are also saying that I drive my car too hard!!! I see they are not wanting to fix my tire so what should I do? Is there a corporate office I can call or anything?|||Give the mechanic's reports that indicate the front end is ok to the Discount Tire manager. If he still will not work something out, go corporate - it is on the Internet.|||Uneven tire wear (which is what I assume you mean by "riding bad") is not covered by warranty. That is a mechanical condition caused by driving habits or lack of vehicle maintenance. It seems pretty clear to me you DID NOT have the wheel alignment checked, just the suspension wear.
