Preventing flat tyres in spoked wheels.

Bradidup

Is there any stuff available to prevent punctures in tubed tyres? I have an old bike with spoked wheels if I get a flat its major job to fix particularly the back wheel.

i think that gunge works on tubed as well as tubeless

Cheers, ill look into it

Sounds like Ultraseal sorta works...from their website

Q - Can Ultraseal be used in tyres with tubes?

A - Yes!

Ultraseal will seal wounds in both tube and tubeless tyres as long as there is rubber recovery and it is not a dangerous wound.

A tube is not one of man's most ingenious inventions, and is very unreliable. The tube is basically made of rubber and synthetics. The wall thickness of a tube is not uniform and rubber content is very critical in terms of elasticity and rubber recovery. A tube that does not contain a sufficient amount of natural rubber cannot recover (close up) after sustaining a wound. It is critical that there be rubber recovery to assure a positive secure clot.

by installing Ultraseal into a tube, the problem of punctures can be reduced. The seal in a tube is not permanent. Tubes squirm inside a tyre at high speed if the puncturing object is left in the tyre and tube, it may rip the tube. Then even Ultraseal may not able to help. We recommend that nails be removed on a routine basis and the tyres air pressure be maintained at maximum PSI to reduce the squirming.

When a tube is punctured, the size of the wound in the tube may be much larger than the actual puncturing object; also tubes are very susceptible to ripping.

I was reading a lot about this last night because the bike I'm getting has spoked wheels. The company that makes Slime has a version of that product for inserting into tubes. I'll be looking more into it and will let you know what I find out.

Nothing will prevent punctures, only (hopefully) repair them. Your toolkit (at least when travelling any distance) should include a puncture repair kit, tyre levers and a high-pressure bicycle pump, as well as a spare tube (or tubes).

Fixed many a puncture this way, and only takes about ten minutes to pump the tyre up to full pressure. Be careful when riding close to the kerb or on other areas of the road where many puncture-causing objects collect.

The 'slime' mentioned above is definitely recommended, but, as quoted above, will not plug all punctures. You could carry one of those pressurised cans - but be sure to remove the cause of the puncture first, and spin the wheel after using the can.

For tubeless tyres, carry a tubeless repair kit and a pump or a pressurised can.

Or else get a scooter with a spare wheel.

I Wouldnt be seen dead on a scooter!!!!

Thats pretty much what I read except they were also saying that you could put the slime into the tube as a preventative measure to automatically seal up smallish (up to ~3mm) punctures.

Esel, are you saying that you fixed punctures at the roadside? I would have thought that was impossible but it is encouraging if that is what you meant

Yes, on numerous occasions. Takes about 30 mins in total. All rear wheel punctures - luckily for me I never had one in a front wheel! :eek:

Impressive

I thought that taking the back wheel off would have been too much work to do at the roadside.

Not on a BSA M20!!, they have this thing the called a quick detach hub which was a joke, job takes about an hour at least, removing chain, brake rod mechanism, rear section of mudguard,a nightmare of a job.
