Well, broke down one tire off the rim, three are being rather recalcitrant. Got the ring off, but, like a few here said, that's just the beginning of the battle! Oddly enough, we found a tire iron that fits perfectly, made the first part easy!
There is some rust, (suprise!)I was thinking of getting them sandblasted and paint them before putting the new rubber on. Any thoughts? Anything I should do, or avoid doing?
