It's the locking ring/split ring that is the problem. When the repaired tire is inflated the locking rings sometimes detach. Causing serious injury to the operator.Dale Finch":3865071o said:Is there a maintenance process to ensure the wheels are safe? What goes wrong with them? I've never dealt with spoke wheels.
The tire with the locking ring is placed in a cage before inflating. Most tire shops will not have the cage.
Family use to own a gas station. One tire with safety ring got my brother. That's when Dad had the cage built.
