I haven't got it and don't want it, thank you.

Firstly, If I have a puncture I want to know about it.
Secondly, I don't want anything in place that will make a proper repair difficult/impossible
Third, Punctures can only be properly repaired by vulcanising. and then only if they are within the tread area and there is no structural damage. Now you get a nail and not aware of it, your riding for say 50 miles at speed with this nail slowly cutting into your tyre wall. That is asking for a blowout scenareo. On a bike at speed, could be a killer.

Looks like squid has said the same as me in the time it took me to type the above

Umh..... thanks Sid & Tim.

I thnk I'll stick to my can of emergency get you home tyre weld under the pillion seat.

I dont like the scenario of having nail eat its way through the tyre wall and then having a blow out. Last time I had a puncture I felt it go down very quickly and i pulled over and was able to try and do something about it. Even though I failed as the tyre was shredded I'm still glad I had some warning and was able to safely pull over.

Using Tahir's experience as an example in this:

The BS-whatever-the-number-is-I've-forgotten limits the number of puncture repairs allowed*, in part this is because the tyre structure can be damaged by a puncture, and at the very least the tyre needs to be examined inside and out, preferably by somebody suitably experienced, in order to ensure that a puncture repair is appropriate.

* And the type of tyre that can be repaired as well, some high speed rated tyres are recommended not to be repaired, simply it is considered that any damage to a tyre intended for use at high stress levels is too much.

That is a very good point, BSAU 159 is supposedly the standard but it seems you have to register and possibly even pay up if you want to read it on the British Standards website , and I suppose it is time I changed my rear tyre as I guess I am pushing it a bit, but I seem to end up with a puncture every month because of the crap on the roads .

Having said that I have on rare occasions pushed my bike past 100 mph, on private tracks of course , and I've not had any problems and I think if anyone did have a problem with a tyre filled with Ultraseal then I'm sure we would have heard about it by now.

I'm sorry but I disagree with this. From my own experience you still lose air from the tyre and you should notice it, so in your scenario the Ultraseal will give you a controlled deflation rather than quick loss of air and hence will reduce the chances of a blowout occurring in the first place. I think Northwind actually had an incident where his tyre was destroyed at speed but because of the Ultraseal he ended up with a controlled deflation rather than a blowout.

Edit: Just found Northwind's post from this thread.

At a more sedate pace, obviously Tyre was fubared but I reckon there's a really good chance I'd been down without it

OK, I have never experienced a blow out on a bike, and I don't want to. I have experienced it in both cars and trucks, and it is the most frightening experience as suddenly without warning you get instant deflation.

In the scenario I suggested you would get no warning. An object cutting from the inside into the weakest part of the tyre does not need to cut all the way through. Once sufficient damage has taken place, the air pressure inside the tyre is sufficient to violently rupture the tyre.

I may be talking complete ******** and if so I am sorry. But if I can visualise such an occurance, it is sufficient to stop me from risking exposure to this possibility. So my personal justification stands.

Ok thats more like it, when i spoke to the chap he did say that yes it will seal the puncture providing its not too large of an object, you still need to get you tyre changed/repaired properly as its just supposed to stop that initial wtf factor and get you home/to a garage which is all i want it for really.

I had it in my first set of tyres. Not bothered since tbh.

I found until the tyre warmed up it was affecting the handling slightly. Just noticeably different. Wasnt happy with that so not got it put in the other sets Ive had.

I used this when I had a scooter and it made it handle a bit poo (not that it was any good before), so I never bothered with it on the SV.

At the end of the day, the amount they recommend you put into your tyre is quite substantial and it does add a bit of weight to the overall weight of the wheel. This will affect the handling.

I mean, I'm no pro at this, but making your wheels heavier will make your bike handle differently or c$%p.

I'd rather spend a bit more time and cut my fingers with a puncture kit then have that stuff sloshing about in my wheels
