Unmounting tires

I was wondering if it was possible for me to unmount the tires on my rims by myself. I do not want to pay the 15 bucks a piece to get them taken off. I have my steelies on the car now but when those go bad I will get new tires for the z24 rims. It will cost me like 120 bucks for unmounting and mounting charges. That is a total rip off if you ask me. Thanks

doing it urself could REALLY mess up ur rims, and if u mess up ur rims, its ALOT more then $120 to get new ones. but if u insist, deflate the tire completely and carefully run a crobar around the edge.
