Replacement Mounting Head
This is a nylon plastic replacement mounting head for Coats® rim clamp tire changers that have a tapered shaft. Nylon plastic heads are great for mounting those expensive wheels without having to think about marring the wheels. Nylon is one of the strongest plastics available so that they may be durable enough to handle the stress of the low profile wheels. However too much stress will cause the head to fail. But it is cheaper to replace a head then replacing a wheel.
These mounting heads only work if you previously own the mounting bracket.
