I'm considering buying a No-Mar tire machine for my garage in The Dalles. The machine is around $600. I would like to mount tires for others for a small charge to off set the cost. Would you be interested if I mounted and balanced your tires (off bike) for $20 each while you wait? I'm searching for a good used machine first. If you come across one before I do I'll mount your first set free! Anyone interested?
