Which of the following most accurately describes the problem?

Recommendations that tubeless tyres being repaired for punctures should be patched on the inside as well as plugged from the outside, have given rise to several new ideas.

One system I have seen recently is that of Pang Chemical Vulcanisers Ltd. which employs a resilient one-piece patchiplug. The plug is moulded in three diameters, the largest and smallest being serrated.

Reason for the serrations: they ensure that the vulcanizing solution is carried right through the carcase of the tyre when the plug is inserted and pulled through.

On the bottom end of the plug a large flange is moulded and it is this that forms the patch on the inside of the cover.

In use, a loop of string is passed around the smallest neck of the plug. This is pulled through the tyre. Solution is coated on to the neck and the upper side of the flange and on the inside of the tyre. When this has dried to a tack finish the string is pulled through the hole on the tyre followed by the neck and base of the plug. The patch is then rolled down on to the inside of the cover and when the solution has set, the surplus section of the plug can be nipped off. The result is a perfect repair—made in about 6min.
