Punctures

[roberts8]

Worn rim tape was my last odd puncture which meant the inner tube expanded into the spoke hole and went down in the first mile. Noticed on my second repair. Good tip when running a fi ger round the tyre is use cloth as more than once I have sliced my finger so now use a cloth when I remember. Worth doing your own repair as surely you will be stuffed when miles from anywhere o your own?

I'd put it in the National Curriculum.

Along with swimming proficiency and changing a wheel on a car. But fitting a mains plug can now be withdrawn.

Rim tape wear / holes are a guaranteed source of repeated punctures. I always check them when the tyres are off.

I see an advantage to patching tubes here. After 4 punctures there would be an obvious pattern pointing to something or 4 random punctures moving suspicion on the brand of tyre.

I have now had four punctures in two weeks and only out on the bike six times and all on roads. All four punctures have been on the back wheel and I have taken the bike to the local repair shop for a new inner tube each time, but am now wondering if there could be something wrong with the back wheel to keep getting these puncture.
Its annoying because I had gone nearly four years without ever having a puncture.
Is there anything I should be checking or would you recommend me purchasing a set of puncture resistant tyres I was recommended these

Thanks for any help

Hopefully this will make you feel a bit better.

Three on one ride at 5.30am 2 on a pot hole and one newxtube exploded on me . Might have to review just carrying 3 spare tubes

That sounds like snakebites from hitting the pothole and then the refitted tube having a but trapped under the bead which exploded on inflation

Are they Brasher Boots I spy there. The old style, not the new Chinese manufactured clogs?

I had a similar experience some while ago and repaired the serial p******es by patching the same tube several times. Each time, I checked the tyre for sharps and found nothing. Having just built the wheel myself, I checked the spokes for proud ends and found nothing. I fitted and refitted the tyre / inner tube combo again and again (obs) and found nothing incriminating. Lastly, in desperation, I replaced the rim tape and the run of p******es ended. Reason: who knows??!!

In addition to the leading suspects already mentioned here, are you running the tyres above the minimum inflation pressure - it should be stated on the tyre sidewall? If it’s too low, and especially if you are a heavy rider, you may be getting snakebite punctures (check the nature of the puncture on the tube, for 2 parallel puncture lines). Also it seems that your tyres are tubeless ready, it may be that they are so tight to refit back onto the rim that the new tube is pinching & puncturing against the rim every time the tyre is being reseated back on the rim after the repair. You can google a few tips/tricks to ease tyre seating if this is the cause.

Having said all that, my best guess is that you have a shard of something sharp stuck in the tyre carcass that hasn’t been removed & causing a slow puncture every time a new tube is inflated against the tyre. Inspect the inside of the tyre really carefully for any evidence of a defect in the lining and remove with pliers or tweezers.

I had this a few years back. Rim tape was worn out.

[thirdcrank]

So long as the innertube isn't twisted - which can cause problems itself - a puncture from the rim well eg unprotected spoke(s) will be on the inner circumference of the tube and so on.

The wheel has been thoroughly checked and all is okay, but I think the tyre has ben affected by the extreme temperatures we get over here in Spain 40Degrees C and higher in the summer and the tyres are five years old and feel a bit thin
also I had a burst valve not so long ago and wonder if that too weakened the tyre rubber so it looks like new tyres and will look at the punctureless alternatives

[peetee]

It’s likely the repair shop has missed some evidence of the cause before fitting a new tube. Either as suggested previously that there is still a sharp fragment still within the tyre or possibly that the inside of the tyre casing is poorly manufactured. I have seen tyres which have multiple ridges on the inside that act like an abrasive and repeatedly damage the surface of the inner tube until it wears through. This damage is very obvious - IF the mechanic spends time looking for the cause. Tyres affected by temperature extremes should show signs of deterioration too so no excuses for the mechanic not spotting that either.
If it were I dealing with this problem I would not be happy to send the bike away without finding the cause. If nothing obvious was visible I would be sure to mark the tyre to match the location of the first puncture and explain what I had done to the owner so that if it happened again they can bring it back to me for free rectification and further investigation.

spot on tc. I have since learnt to reflate the tyre with a bit of air in the tube. Sadly I had also made the mistake several times before.

That's an interesting question SimonC because I hadn't used them for some and for some reason I thought I would dig out my Brasher boots out and go for a walk. Turns out that they are actually Zamberlan Ibex good but a little heavy so I have brought some lighter Berghaus boots. But its interesting to read Brasher boots weren't what they once were.
