Just had a read of the NZ standards for tyre repair and the H&S documentation for tyre fitters. The "rules" were written in 2001 with an amendment in regards to tread depth coming on may 1st this year.
Anyway, They don't say external plugs are illegal , in fact they are never mentioned, They show best practise for fixing a tyre and it involves removing the tyre, cleaning and shaping the puncture point and fixing from the inside.
Interestingly enough their is special information for nearly all other vehicles including ATV's but no mention of (two wheeled) motorbikes.
Personally I've seen a couple tires split after having a plug put in them, and one where the plug came loose, So I wouldn't use one, well, maybe to get home. But if it looked like the mess posted in the pics earlier in the thread I'd be a tad worried.
Ahh, you just need to pump up your tyre more often now. :-)
Yeah, the whole set set me back $600, and they are predicted to last aroudn 6000-8000 km apparently.
Yep, Mike also said this. The plug they do from outside is for 'temporary repair only', and is only good for getting you home. I've been riding around like this for over 3000 km now. Now that it's fixed, I should get abit more life out of these tyres
They're good, I've had the rear come out a few times mid corner and always managed to bring it back under control without any issues.
Darn would not think Cycletreads use a temporary fix. I got 2 mushroom plugs on my rear and it has lasted for more than 3000km. They did recommend to not ride it more than 200km/h though.
Bikerboy your bike would have come with BT016's as OEM which are crap and would not last long. Somehow I think the BT015 and 016 are hard tyres compared to Michelin PP. But tyres are always a personal choice.
Don't just live to ride but ride to live.
That'll buff right out.
I may not be as good as I once was, but I'm as good once as I always was.
Well here's the 'proper' fix done by Mike at Drury Tyres
In other news I found a set of Michelin PP in my shed, guess I'll try them on next.
Last pic looks to be the real thing.
Had mushroom plugs in 3 or 4 tyres (all rears - the front flicks the nail up and the rear rolls over it while the nail's standing up) and never had a problem in many miles, even with occasional sustained bursts of high load & speed (where legal).
Never worked out what the NZ regs for this are like compared to other places, but someone seems to like making up rules which are different to justify their existence. Domestic hot water and Legionaire's, for instance. "Why make a reg to heat water to 70C, only to fit a tempering valve? Oh, you make tempering valves..."

What an irresponsible idiotic forum troll suggesting something that may endanger others. Don't listen to this twat.
Certainly, if you have even a half brain, you'd know that introducing another matter into the tyre would add intrusion volume and upset your tyre pressure. The most logical thing is to calculate the probable volume of that puncture screw and deduct that from the air volume in your tyre. That way you still have the optimum tyre pressure and avoid running the tyre too hot.
(OTP psi + SV) - SV = OTP.
where OTP = Optimum Tyre Pressure (in psi) and SV = Screw Volume (in cubic mm).
Happy to help.
