I picked up a pair of new Clement Futura tubs as spares & was wondering if it is better to inflate & hang them or just leave them in the closet lightly folded? I don't have a pair of spare tubular rims on which to install them.
If you are going store the tires without stretching them on rims and you plan to store them flat as 11.2 suggest, I'd inflate them enough to get the wrinkles out from the folding. I'd probably leave them inflated for several days.
Personally, I just hang them in the garage. I'm sure that's not good for the tires, but I buy relatively inexpensive tires.
