Tyre question follow puncture

sketchley

Yesterday Morning I had flat, Noticed this when cornering on cobbles and back end slid out badly, I can only guess that puncture had only just happened or I would have noticed earlier. Quick tube change and I was off again. All fine until about one mile from home in the evening following 25 mile commute and lap of RP, once out of traffic noise sounded like back wheel was rubbing, after investigation noticed tyre had jump off rim slightly near valve on one side and was rubbing against break block. As soon as I deflated tyre a bit it jumped back on. Left it inflated back at 110psi over night all looked fine this morning and no problems on 16 mile commute in.

What I don't know is if this was a problem I caused when fitting the tyre after flat or if problem was caused when a slid out on the cobbles....

Question is I have a spare new tyre in the office should I just air on the side of caution and fit it anyway or carry on and see if it happens again?

Did you use the nut on the valve stem?

If you do, don't tighten it up fully before inflating.

Sounds like a poorly re-seated tyre.
Alternatively, tyre levers can damage the tyre's bead, but you wouldn't be using a tyre lever that close to the valve?

+1, it's always worth going round the tyre after you've fitted it to make sure it's properly seated.

Yes. Seems to be ok now, I'll keep an eye on it though.

Thanks

3 bits of advice from me -

1) As suggested by @will3 - don't tighten the valve stem.

2) Prior to inflating - push the valve stem in and out a few times. The rest of the tube tends to be pushed into the tyre but the bit next to the valve isn't. This can result in the tube being pinched there.

3) Pump the tyre up and then deflate and pump it up again. This helps the tyre seat properly. If I'm near home I often waint untill I get home as I know I'm going to reflate with my garage pump anyway.

I suspect No 2 was your problem - tube under tyre at valve. Your tyre is probably fine!
