I have recently found the INSIDE rim of my split-rim wire wheels has split around the circumference of the wheel allowing the tyre bead to bulge out. Has anyone else had this problem, and how did they fix it? I am lucky that a friend saw it while parked, but I have been driving on it for some time I guess. Can they be welded? or is it fatigue that requires replacing the whole wheel? This is a problem down under with so few spares!
