Daang, that thing looks like brand new, Kori!! Congrats!

I remember when I first got mine, it's one very special feeling!

Very nice Stan, that's great to have a metal bodied machine.

Bummer, sorry to hear the news.

But ditto everyone else, your tires can be used if you run inner tubes, it's the same thing as a bicycle tire. FWIW, the tire itself would no longer be holding the air so it would not be escaping through the cracks.

But, there is nothing wrong with replacing them with new ones if that's what you prefer to do.
