I was thinking about changindg a tire and came up w/some ideas that would make it easier: 1. EASY WAY TO PREVENT SCRATCHING THE RIM-first let the air out and break the bead, then on the side you will be prying on the tire put a think tape all around the rim folding it around the inner side of the rimm and also the outter. You may have to put a couple of layers depending how thick it is(I used a masking tape and then covered it w/duct tape so I wouldnt have to clean the rim of the resadue from the duct tape) Then when you put the tire back on when it on then simply remove the tape. 2. PREVENTING PINCHING OF THE TUBE- Go to the local hardware store and get a thin layer of foam and stuff it around the tube where you will be using the tire irons to put on tire back on(You can use a piece of double sided tape to have the foam stick to the tube) 3. PUTTING A TIRE ON W/CLAMPS-I have never tryed this and it might not work, I was thinking you get the twist clamps maybe 8 or so and just tighten them all aroung until the tire is on using a leverage bar to make them extra tight? I am not sure this one works???
