Hi.
Three years ago I had a rear tyre failure that looked almost identical
except the tube did not explode it just went flat and stayed on the
rim. The cause was a very slight upward tilt of the leading edge of
the V-brake pad. It was *BARELY* touching the tyre. *BUT*, that *WAS*
enough for it to wear through the tyre sidewall on an 80 km/hr descent
even though the brakes were only being applied intermittently and
lightly to modulate the speed. The tyres were IRC 1.5 inches x 26
inches mtb slicks.
Check brake pads frequently because as they wear their upper edge can
come in contact with the tyre bead and cause this kind of failure. Or
they can become slightly out of allignment and give the same result.
I hope you make a full recovery.
