I have not done this but it seems to me if you bought tires with symetrical tread patterns you could demount, rotate them then remount them for maximum life. I agree with Pizzguy our xfires by design were never intended to be used as commuters. My xfire is my fun and enjoyment outlet. Many people stop me and comment how much they like the car and are especially surprised when they find out its age. The different size wheels and suspension system were implemented for technical reasons.
