Rear tyre permanent repair

[rapid van cleef]

well, did a track day a few days ago and was very dissapointed to discover a puncture in my rear tyre very early on. came off the track and did a repair with one of those kits with the 'dog turds' etc.

the tyre is a pilot pure and has only done around 1000 km so im pretty gutted and dont really want to buy a new rear if i dont have to.

apparenty theres a process where it can be 'vulcanised' on the inside to fix it properly.

the bike is a zx10.

can anyone recommend a tyre repair specialist in the bay of plenty?

or, do i have to take it off the bike and send it away.

yes, i plan on doing more track days on it. however, if the general consensus is that its too dangerous, then i wont obviously.

some advice please guys

thanks

Proper vulcanising is not done often if at all now days, modern construction and materials can be ruined by the heat involved, (I have seen tyres develop flat spots due to incorrect application), there is a patch thats like a mushroom, the flat is glued in and the stem runs through the tyre to the outside, these are great for road use not sure about on the track though.

I've never had a dog poo repair fail.

Dog turds do the job.. I've had to use 2 turds to seal a hole couple of times.. I was told they were speed rated to 40k, but ive seen over 250 clicks on many occasions without them failing.. and right down to canvas

I've used many different tyre can sealants.. they worked fine ( Ive tested them at 250+)

Patch is the best option.

Dog turds are not as good as the proper patches, but I haven't had a dog turd fail yet.

Most shops should be able to do a patch, it's a disc with a spike on it. Glue it to the inside of the tyre, sticking out the hole, and cut the end off. It will only patch up to a certain size, and the hole can't be on the sidewall etc.

I can't find Pilot Pure in the Michelin literature.

Power Pure tyres are W rated, tested and rated for use at 270kph.

Guess the rating of a repaired one?

Once I got caught with a puncture in a near new tyre, I used it on the road for a while but it was replaced before it was worn out.

People say they've never known a dog turd to fail. A ZX10 on the track? Potentially serious consequences if it was the unfortunate first.

Easy, I've had a pirelli diabolical to over 300kph plenty of times with the proper 'mushroom' repair. Safe as houses if it's done right.

I've had a dog turd fail - almost positively installer error (my 1st attempt at one).

Having the tire rapidly deflate at 100kph round a 55kph corner certainly focuses your attention.

I still use dog turds and have no problem using them for the life of the tire, including track days. I guess it's a case of "Better safe than sorry" vs "She'll be right" and what side of the fence you're on.

Dog turds are safe as long as done properly but the LTSA says they are for temporary repair only , like spacesavers on cages . An internal mushroom repair is safe and legal if done properly and the LTSA says you can have up to three in your tyre . Tyre manufacturers say not to repair tubeless tyres but they would say that .
LTSA I believe is an acronym for Lazy Thick Stupid Arseholes and if anything happens overseas they make laws for NZ from it but we don't have an Autobahn

Thanks for the replies guys.

and the tyre is a power pure.

IIRC the reason this was done, was because you cannot see the full extent of the tyre damage from the outside. It is not until you pull the tyre apart that you can inspect it properly. When I was in the tyre game, it was amazing how many Dog turds had not gone thru the puncture hole. And how many dog turd repaired holes had other damage relating to the original puncture. Some with cut sidewalls, just waiting to go bang.

They aren't safe by any stretch of the imagination even when done properly if you haven't demounted the tyre and checked for internal damage and if you're going to do that you may as well repair it the proper way

It was also because there was a fatality associated with a tyre repaired in that way

I have also seen them with the original object that caused the puncture still in the tyre with the "dog turd" repair

Either the mushroom shaped plugs or vulcanisation are the two best methods of repair, both are a permanent repair if done to the correct standard
