As I understand it the problem is not that the same part of the tire remains in contact with the floor; rather, it is that the entire tire needs to get "exercised" by being run at speed , thereby mixing up the chemicals in the rubber which act as preservatives. I doubt that shuttling it around the garage will do anything to help the tire, but at least that might motivate us to keep them inflated! <img src="/images/graemlins/wink.gif" alt="" />
