I use a skill saw with carbide blade to cut through the wire bead. If the tire is good and you want to save it, you have to make sure that the tire bead is loose from both sides on the rim. Couple of pry bars - old car springs work fine, take small bites to start with and make sure the tire bead away from you is centered in the rim this give you some free board.

To install the tire onto a steel rim, soap the bead and rim with watered down dish soap, use a heavy hammer to work 2 to 5 lbs the tire onto the rim by tapping onto the inside of the bead. I can install a tire at home just as fast as the tire shop all for free.



If I have a lot of good tires I usually sell them to a shop that specializes in used tires, it's not worth my time dealing with warranty and whatever.

Another thing is big truck and loader type tires, the casings are worth money for re-capping, it's been a long time since I have sold any so your on your own here to find a market. Try the yellow pages for a capper near you.
