Hey all, i need to remove the tires on my moped and put in new innertubes. I have a few questions. One Is there a way I can get these things off without a special tool? The other question is, is it possible for the tires to get bad of old age without being used. They seem rather hard and I know that the bike has not been used for several years now. They don't have much wear on em either. FYI this ped was NOT taken care of by the previous owners. I got it for free and from the condition it came in it looks like their kids ran it into the ground almost literaly and once they could no longer start it the thing just sat in a garage for years.
