Tire mounting and balancing is getting pretty expensive these days, I was thinking of trying to do it myself. I've found 2 balancing systems that use beads. Equal http://www.imiproducts.com/equal/index.aspx and Dyna Beads http://www.innovativebalancing.com/service.htm Both systems seem relativly inexpensive. You can install the beads while mounting the tire so you don't need expensive applicators. My question is, how would I go about mounting and balancing a tire? I'm not planning on purchasing a pnumtic machine like at the tire shops (well, not unless I can find one real cheap!). How do you do it? What tools do I need and where can I get them? Is it difficult? How hard is it to seat the bead? I do have a large 5 HP compressor. Is this a waste of time? I don't want to spend an entire afternoon mounting tires for my dually and then have to see my chiropractor ther next day. Anyone ever use one of these? http://cgi.ebay.com/ebaymotors/Speedway-Series-Portable-Tire-Changer-05093_W0QQitemZ4623243719QQcategoryZ63699QQrdZ1QQcmdZViewItem Thanks, Eric M.
