Temporary puncture strings are temporary

[kramdra]

They do eventually lose their sticky. I had done 11.5k miles on the repair over 10 months - last 1.5k it had a slow leak around the string. They are still great repairs, but any future punctures I will have the tyre off within a month for permanent repair.

Took tyre off last week. The newer fitted string (2k miles) took substantial effort to remove from the inside and was very sticky, however the old one (10k) popped straight out. This tyre also had a professional repair which was good.

Ordering some professional style mushroom patches and glue for future repairs. Is there any particular way they should be fitted? Do i need a stitching tool? Are they applied cold? I saw mention that they can be applied hot but no explanation of how.

Cold is fine. No idea what a stitching tool is. I've found they actually work better if you make the hole a bit bigger when it's a tiny one. And don't cut them off too flush with the tyre (or while you're pulling on the end) as it will sometimes then disappear into the tyre and you've got a puncture again. Leaving a couple of mm sticking out seems to stop this and it soon wears down flush.

So "temporary" in the sense that it only lasted for the (long) life of the tyre?

Did you splurge any rubber solution in there when you fitted it?

Stitching tool?

Do you mean something like a thin screwdriver with a hole in the end that allows you to push the plug in from the outside, without having to break the bead?

This type of tool works with the smaller 'mushroom plugs', but I have no idea what it is called - and I have never seen one that works with 'Patch Plugs'.

Like a manual version of this Plug Gun.

Patch plugs can be applied hot, by clamping it in a special G-clamp type device, which has an electric heater in the part that goes inside the tyre, but a chemical vulcanising solution can be used to do the job cold.

Edit: Just found This.

I have never gotten 10k out of any tyre on two wheels.

This doesn't seem relevant to my interests.

I spent about 2 months of my apprenticeship in the Tyre Bay, and we had a Vulcanising machine similar to the one on This Website.

To use it, you identify the puncture and mark it, then remove the tyre completely from the rim. After cleaning-up the inside of the tyre with emery cloth, you apply some rubber cement and the special patch. The tyre is then hooked over the lower pad, which contains the heating element, clamp it in place with the top part of the machine, then switch it on.

There was no temperature setting, but it had a thermostat that you could hear clicking on and off as it heated up.

After about 5 minutes, you switch the machine off and wait for it to cool before undoing the clamp and re-fitting the tyre.

It made a pretty good job of it too - there's no way you could have pulled the patch off afterwards, and it was deemed to be a permanent repair.

It's not the sort of tool you would have in your shed though, and I think most tyre places now, use chemical vulcanising fluid that doesn't need heat - that's if they do puncture repairs at all!

Interesting - had a read through google. It seems usually the tyre should be baked afterwards in an oven.

The BS for tyre repairs does say chemical repairs only in the centre 75% (area T) where as hot vulcanised repairs can be anywhere (area W), sidewall included assuming cord not damaged.


In 1970, cold repairs were banned, but then were allowed when they improved. Most repairs are now the cold type. Cold repairs are only allowed with mushroom plug-patches. Plain patches are for tubes only.
