Hey, I need advice, I now live in Az.and have 3 sets of tires/wheels,I like a different look, ever so often on my cars, so I change em, BUT here's My question,, How do I store tires and wheels not on my car, little bit of air? on wheels? like to hear from a tire expert. When I was young, all tires came wrapped in paper, not anymore, anybody know why? I have them away from SUN, but not in a climate -controlled atmosphere. so they get plenty hot.. thanks, I learn more stuff here than my 3 senior years of hi school.
