Make a tire boot. Get an old race tire with as little tread as possible. Cut out a section about 1 1/2 long. Then CUT OF THE BEADS. Just slip it in place. It has nowhere to go since the ends of the boot will be resting on the rim bed.

I've ridden over 1000km with a tire like this.

I wouldn't do it now, though. I'm too olde for that crap.
