Put me in the ol' guys corner. It's hard enough work just getting the wheel off and on without wrestling with the tire itself. Besides the local tire guy does it for $7 ... well worth it and the tubes are pretty cheap too. For around $20 - $25, he should have you back in business. Now, if he'd just go back to making house calls to fix tractor flats, life would be even better. At the farm, I had 13 flats and 4 new tubes in 2003 but only 3 and 1 tube last year. I love that SLIME!!!!!!!
