Just before leaving for an important appointment Monday I discovered my rear tire was flat. Didn't have a spare tube and needed to leave within minutes. Pulled off the clincher tire and tube and put on a spare tubular tire I had hanging around. Worked perfectly and allowed me to make the appointment on time. Weird combination = tubular tire on a clincher rim but it worked well enough to get me to and from the appointment.

Ummm... perhaps you should carry some duct tape. There are some
articles and a few videos on how it's done.

I've only used it once, on someone elses tire, because the rubber
cement had dried out in three out of three patch kits available. It
apparently worked as there were no threatening messages on my
answering machine when I returned home. The only real tricks that I
recall are to make sure the tube doesn't have any crud or baby powder
on the surface, and to NOT wrap the tape all the way around the tube
so that the tube can expand when pressurized.

I don't think it would have worked with narrow high pressure tires.
The one I patched was only pressurized to about 50(?) lbs. I don't
think the duct tape patch would have held at 100 lbs.


On one long tour, our Continental Top Touring tires developed worrying bubbles
in the sidewalls. This was in remote North Dakota. I reinforced the system by
wrapping the tubes loosely with duct tape. I was trying to approximate the
diameter of the inflated tubes. I can't say for sure it worked, but we didn't
suffer any blowouts.
