Yesterday, I changed two more tires with the No-Mar classic tire changer. I love that thing! It would be nice if the adjustment on the cams were a bit easier to get tight and centered but overall it is well made and easy to work with. I changed two tires for a friend's Buell motorcycles and should get to do two more later next week. I can't wait until I get the No-Mar mounted on the floor though. It does kind of stink mounted on a 2.5' x 2.5' piece of plywood. It is especially difficult if you don't have someone standing on the other side. I figure by the end of this summer my No-Mar will have paid for itself or at least be close. It will be infinitely easier to use when it is in a large space, mounted on the floor, and an air conditioner keeping the atmosphere just right! I can't wait to move into our new home.
