It sucks even worse when trying to break the bead on the former spare, which had sit on its side in the rain much too long. There was rust bonding the bead to the inner surface. It took an hour or two to break it loose. Though somewhat corroded, it's still usable as the spare wheel, IMHO. After that, getting the (ruined) tire off the wheel was comparatively easy.
So, an entire morning gone and I have half the dismounting done, with two mounts left to do after that. I hate this already! -- Jim
