Thanks Builder. Good steps to follow. All the beads are broken and just need to pry off the tires. Will try some of your suggestions this evening.
Dave, no they aren't split rims. However, when I get to the split rims I will just be taking the toires and tubes off and not reusing the rims. Is there a danger in demounting the split rims? I thought that was only when you were airing them up that they caused a problem.
