There seems to be very little of any mention of plugging kits for emergency get-you-going tyre repair following a puncture.

The two types - the "doughnut" type and the "string" repair kit.

Both are a valid, practical and effective method of plugging a hole in a tubeless tyre.

Most punctures over my driving career have been down to, nails, bolts, screws, and pop rivet shanks in the rear tyres.

The front tyre throws the object up and the rear tyre collects it so it seems.

I carry a string repair kit on each motorcycle because if you can't repair a puncture you are stranded waiting for recovery.

The other dodge taught to me by the motorcyclist manager of a national tyre depot was to carry a selection of large countersunk self-tapping screws and a tube of rubber solution. Pull the nail out of the puncture, put rubber solution on the suitably sized screw, drive it into the hole until it's under flush, inflate the tyre with your carry on board CO2 capsules and on your way to get to the next garage with an airline, then inflate to the correct pressure.

(The CO2 capsules are the standard 12 gramme sparklets threaded type included in motorcycle puncture repair kits - use two for a bike tyre - four for a car tyre they cost about £4 for a box of ten)

This dodge got me home 150 miles once, still held up for a week until I could get a new tyre of the correct size.

Have read about these in the past and considered buying some for the Caterham but as you say they seem to be more popular with motorcyclists probably because its easier to identify and then access the offending object with no need to take the wheel off. It would be easier on the Caterham than any "normal" road car but even on that to avoid the risk of death doing an offside puncture repair you would still need to take the wheel to a place of safety and then pump the tyre back up and I have yet to find a reliable electric pump that does not burn out before a tyre is inflated.

Will stick to the Holts can of glue that repairs and inflates a tyre. I accept the tyre will be gash after (at £50 a tyre its not the end of the world) but unless its a slash or damaged side wall should get me home. Then its recovery.

Used the string things a lot on my Sierra DOHC here in Taiwan, which seemed to pick up a lot of nails, Never had one fail.

I have a kit (and a bicycle pump, CO2 bulb inflator, and a USB chargeable pump) for the Skywing but have not so far needed to use it. Narrower tyres, which I suppose are statistically less likely to pick up ironmongery.

It MAY also be relevant that I dont fail so many students these days (fewer, smaller, and better classes) and dont generally park on campus.

Mildly surprised the string things are popular with motorcyclists, though. The "ÿour only contact with the road" jive is only true with them until something goes wrong.

When we took delivery of our new Honda about 20 months ago, the owner of the garage pointed out the goo, but said that if we ever did get a puncture locally not to use it but give them a call so that they could recover us and repair the tyre, because it rendered the tyre unable to be repaired.

See in one of my posts above re repairing after using puncture sealant.
