My son's rear tire popped the other day. 44cm frame 650c tires, bike basically unridden, stored in a ot Florida Garage for 8 years before we bought it.
Replaced the tube, then noticed that the tire has a split in the side, and the tube is expanding into it, so it's not safe to ride
I was surprised that the local bike shops don't carry ANY 650c tires as stock. -They'll order them for you, but it'll take a while... In the end I bought a couple online, at the suggestion of an LBS employee.
Why are these so hard to find? -Are they being phased out or something? -Should I be stocking up, or something? -I don't even want to keep either of the old tires as 'emergency' spares... I just don't trust them at that age/condition.
