I can get a pretty good deal on a set of tires I will probably need 2 years from new. Tirerack price is $330 each. I can get 2 now for $220 each and it's brand new. With that said, if I store it in a black plastic bag in a non heated garage, will this affect the tire. I am aware that over tire, tires do *bloom* but I think this is more of a UV issue. Should I grab the tires at the good price ?
