No to tires for life!
While I had a pleasant buying experience at Legacy, I was skeptical of the "tires for life" program they offered. Turns out for good reason. Every time I took my car in for service, I requested service on the tires to keep the program valid. On my last visit, I was told my program was void because I did not keep up. I was furious and from the sound of it, they void them all the time and don't care. It is a racquet and I HIGHLY recommend not to do it through them.
