Thanks to Pat W., in Powell, Wyoming for the great review of the Phoenix tire changer with helper arm (PWC 2950A) / wheel balancer (PWB1530) combo.
Pat ordered the set that includes the helper arm (2950A) for the tire changer. The helper/assist arm is beneficial for the mechanice working on performance tires, run flat, and stiff side wall tires that require heavy force and extra hands. We do sell it separately, but it's definitely helpful to order it with the machine for convenience, if you can predict that you will need it down the road! We also offer a model of tire changer (PWC2950) that does not include the helper arm, but it is fitted for one, so you can add one at any time!
"So far the machines are working great, no issues with either one. I have done just a few sets of tires so far and I'm really happy with the machines performance. I've have never used these types of machines in the past but find them very easy to operate."
