I was riding home last night and heard a rhythmic noise from the rear wheel. On stopping I found this:
The bead had parted company with the sidewall, and the inner tube was herniating out in a blister. The noise was this lump hitting a brake every wheel rotation. The tube is not punctured here.
Clearly the tyre is dead, but I still need to get home. So I tried to reinforce this with duct tape inside the tyre, and more tape wrapped around the innertube at this same point. The tape was about the same size as the inflated tube would have been so not tightly constrictive.
This lasted me around 3 km before losing air. Instead of struggling on for the rest of the ride (another 25 km) I walked back to work and picked up a spare bike.
QUESTION: How would you have temporarily fixed this to get-home ?
So its a week later, and I finally got the chance to inspect this. Turns out, I had a legitimate puncture elsewhere on the tyre that night, and this dirty-hack with duct tape was still holding fine.
I was slightly tempted to patch the puncture and reassemble with the duct tape in place, just to see how it copes but then common sense prevailed so I binned the tyre and fitted a half-used spare.
