yeah those are standard rim clamps. still good for not scratching wheels as long as you keep the plastic duckhead on it. ive seen places use metal ducks because the plastic ones wear out from time to time and theyre trying to save money. metal ducks are the worst. as far as tire machines....this is the model i prefer using ....
its the coats 9024e. they use hydraulic arms on the side to push down or lift up the tire on the wheel. its great for low profile and custom wheels. also opens up to 24'' stock. not many shops use them cause of their expensive cost, but its a great machine.
