Tyre explosion
Hi.
I fitted a new set of Schalbe Durano Plus tyres last week. On my commute home the rear tyre had a "catastrophic failure" - gunshot going off, immediate deflation and riding on the rim. They had felt a little "squirmy" on the way home but I thought I was being paranoid (I always am with new tyres, and find rear tyres always squirm a it) and I had pumped it up this morning to about 135PSI (they're rated to 145 according to the label on the tyre) and it had felt hard to the touch when I felt it at a set of lights, but perhaps it can't be ruled out that they were a bit low.
Anyway, the result is a giant hole straight through the tyye and inner tube - you can literally peel back the hole and there's rubber hanging off - not good! It looks like it's exploded rather than been slashed - the rubber all comes out the way and is a state, rather than there being an obvious cut from glass. The inner tube had a hole about 2cm long (across a seam I should add).
I'm trying to work out if this is normal, or rather can be expected to happen or if there's foul play, so can anyone suggest? Was it:
a) bad luck, just one of those things, but a new tyre and get over it
b) low tyre pressure
c) high tyre pressure, they're rated to 145PSI but you shouldn't go anywhere near that on the rear tyre, especially not when you weigh ~100kg
d) you didn't put the inner tube in right when you fixed them and over time it's burst
e) I don't care what you did, a tyre should never have a hole blown in it like that
Given they're new I want to send them back to Wiggle as faulty, but I don't know if it's just tough or not.
Thanks in advance for any thoughts!

I would go for D.
If the tube gets crimped or folded in the tyre this can happen - I fitted some tyres badly to my g/f's bike, exploded on a 30mph descent and blew the tyre off (though didn't rip it). I am still making up to her :oops:

It could be that you had a glancing hit on a stone or similar that pinched the tyre and inner tube against the rim. I did this in the summer, saw a large stone in the road just too late and clipped it with my front wheel. Bang, instant deflation and a surprisingly big hole in the tyre sidewall and inner tube, both non-repairable. I was using Ultremo Rs at 120 psi.
135 psi sounds a bit high to me. Closer to 100 would still protect you from normal pinch flats and probably feel more secure and comfortable to ride on.0 -
Thanks guys. I guess it's just tough luck and I'll have to stump up for a new one (ouch) - and I'll make sure the tube's in right and lower the pressure a bit just to be sure!

Pumping up a tyre too hard just puts greater stress on the tyre e.g. over-inflate a balloon and see how easy it is to puncture in comparison to a partially inflated one. Can't say for sure whether is was down to a trapped inner tube or road debris that caused the failure - more likely to the former.Make mine an Italian, with Campagnolo on the side..0
