Went to the local bike shop to buy new tires for my bike and the sizes are no longer 4.00X18 or 3.00x21 they are something like 110-??-18 or something like that. If you have the right #'s it would be greatly appreciated.
Thanks

A good place to look ,Rich, is in the "Search". There was a discussion on just this topic a while back with some excellent info given. I printed it out for reference, myself. Hope this helps.
