Continuous Rear Wheel Puncture - Help

[andy_wrx]

I'll join the majority is suggesting there's likely to be a thorn or piece of glass or something embedded in the tyre.

If, as suggested, you mark the tyre and tube and rim, then when you find the hole in the tube it'll show you which bit of tyre to look at. If the puncture is on the inside of the tube though, it could be the rim which is doing it.

I spent ages the other week fixing a puncture, a complete flat overnight, because whilst I could easily just shove a new tube in, I wanted to find the thorn or bit of glass/wire/etc in the tyre which had caused it, rather than just have it puncture the new tube in-turn.
I quickly found the puncture in the tube, but couldn't for the life of me find what had caused it, ended-up hoping that whatever it was had come out of the tyre afterwards - presumably was, because 300-odd miles later it's still OK

Can't add anything ere really - tiny thorn ends, glass etc all hard to find - the bit's of thorn are real barstewards !!!! - do carefully sweep your fingers round the inside edge of the tyre to feel any sharp bits !

I was getting puncs cronic with my last tyres - ended up buying news but different make !

Did as instructed and marked out the tyre -after (extremely) close examination found the smallest shard of metal. Just fitted a new tube - so fingers crossed for tomorrows journet - cheers for the advice.

possibly the thorn is still on the road, attatched to a twig. you rode over it and it's still there awaiting its next victim
