Chance are the tires are not brand new. I would tend to agree with the suggestion that if they are already a few years old, just put on new tires when you decide to get mobile again. That way you don't have to worry about them sun fading, cracking, getting flat spots, and any other problem that some folks go to great lengths to avoid. Some of us do nothing except buy new ones when they are needed. This is the easiest way I have found. Trailer tires should be changed every four or five years anyway. Those blowouts can cause a lot of damage at highway speeds.
