Thats encouraging, though as far as I can tell from internet searching it seems a bit controversial.
Tyre industry sources, and the (US) National Highway Traffic Safety Administration, I suppose predictably, say a tyre should only be repaired by qualified personnel using industry-approved equipment and requires both a plug and a vulcanised patch on the inside. For example:-
nhtsa.dot.gov/cars/testing/n … epair.html
They also disapprove of inner tubes, which I’ve used without problems when I couldnt get a rim seal with a tubeless radial.
Continental Tire Product Service Information Bulletin PSIB 05 – 01 [generaltire.com/generator/www/us/en/generaltire/automobile/themes/generaluniversity/drivers_ed/tire_repair_en.pdf ] goes a bit further and states:-
“This assessment should also take into account the complete service life history of the tire including inflation, load, operating conditions, etc…”
Since this information can almost NEVER be available, this implies that a tyre should almost NEVER be repaired, even by pros. This seems to pretty much describe the situation now in the UK where they are much, much more comfortable selling you a new one, and charging you to dispose of the old one.
All I could find on the other side of the argument (apart from some US eBay ads for repair kits apparently similar to those you can buy here) was a discussion on “Patch versus Plug” on autorepair.about.com/library/a/1a/bl028a.htm
I dunno how authorative this is, but it doesn’t have any obvious vested interest. It considers patches and plugs as alternatives, and says plugs worked well with cross-ply tyres, made a lump in early radials causing a switch to (cold or hot) patches, and then improved “self vulcanising” plugs were introduced which are now the method of choice because they don’t require tyre removal. I imagine/hope that the Taiwan repair kits use these. I havn’t seen any for internal patching.
So I dunno, but I’m inclined to get one and try it, IF its got instructions with it that I can understand. What have I got to live for, anyway? I will put it on the back wheel though.
BTW theres a (UK?) company called Autoseal that sell a fibre-bearing liquid thats supposed to slosh around inside the tyre keeping it cool, and seal any holes as they occur. Interesting idea, but I’ve never used it.
