Changing the front tire (dunlop 756) ... should be easy ... I didn't let it sit out in the sun 'cuz i was in a hurry ... getting towards the end by the rim lock ... keep flipping the tire over to get the tire off the bead on the opposite side so I have more tire to work with ... SNAP!! ... the wire beads bust in half. I don't suppose there's a warranty on these is there?
