Somehow I've ended up with 4 sets of good tires and no particular use for them.
I want to store them under my deck, which is covered from rain and sun, though still somewhat damp.<br /><br />What's the best way to store them? Should I lay them down flat or stand them up? Should I put a board underneath or can they just sit on the dirt? Some have wheels...should I let the air out of those?
