Rightly or wrongly I wouldn't even contemplate using slime.

I used to get Z rated tyres repaired by my local tyre man. He did poit out that it wasn't reccommended, but never mentioned it was illegal. I think the problem is the rates speed of the tyre and the ability of the repair to perform at the extremes. He did make sure that he pointed this out each time and on a couple of occasions had me sign a disclaimer.

The repairs he did were called vulcan patches. Involved removing the offending article scrubbing up the inner area around the puncture then sticking a patch on the inside that was heated into place. The finished article looked like a big blob of extra ruber melted into the inside of the tyre.

Personally I had this done a number of times, once three times on one tyre. At over 100 quid a hoop and a tenner a repai it's a no brainer.

I've had the same type of repair done at my local bike shop, where I always buy my tyres, never had one fail. I trust a bloke who knows he could easily sell me another new tyre, as I have been using him for years, but still suggests I try this type of repair.
Would only do this if tyre is relatively new and the puncture is in an area that that can be safely repaired. Also had similar repairs done on a few car tyres with no problems, so would agree with Dale.

dont confuse "slime" with "ultraseal" they are two different formulas. I have used slime before mainly in pushbikes to good effect and also once in my front tyre again with good results. you do pay a bit more for tyre changes if you go to a bike tyre fitting place, i guess any excuse to lift the price. this has never happened at national tyres, where the manager is a biker and does a splendid job.
How about a pair of Road pilot 2ct for £159.00 fitted to loose wheels.

I believe in prevention being better than cure. After much research I decided ultraseal was the best, do a google on "ultraseal" and you will see why I use it.

I must add that in over thirty years of riding, i have never had a delamination until last year, i will gladly wait another 30 years for the next

Conti did refund my purchase price, cheaper than a coroners inquest, which could have been the result.

It was quite funny though riding at 20-30MPH on the CB13, being overtaken by all, inc mopeds!

Looks like I've got a slow puncture, cause not obvious (I've been round the tyre three times and there's not so much as a piece of gravel in the tread), so I'll be thinking about slime, ultraseal etc.

Bit embarassing that I made it to work with 9psi in the tyre - that explains the vanishing chicken strips then

Bang in the Ultraseal then mate.
This is where you really miss a centre stand.
Last time I used it on my old CBR1000F I squirted it in then just left it running in gear on the centre stand for 5 mins. to spread it around nice and evenly.
Having said that Ultraseal is better than slime if you can't spin it or ride it straight away, as long as you can spin the wheel a bit or have a little run you should be OK. The only time I used slime it seemed to lay heavier in one area reckon the wheel needed spinning a lot more to spread it around evenly.
Good luck with it!

The last 'slow puncture' I had turned out to be the valve.
It was the seal between valve and rim.

Check it with soapy solution - ultraseal won't help if this is the case

spot on Fausto, kiddies paddling pool fill with water, immerse afflicted wheel and slowley rotate. leak should be evident. if this happens in August you can then put your feet in the pool. Lovely.

Nice idea but I didn't expect Firestarter would have taken the kiddies paddling pool to work with him on the bike.
Plus if it is a rubber valve seal Ultraseal might just get him home if he's stuck at work with a flat tyre.

Still he can always bathe in the pool whilst he waits for help.
