These bike tyres are as good as run flats!

Thanks data, i know there was another recent thread where ultraseal was discussed and i did post in there about my experience with that stuff but you must have missed it.

I used this on my previous burgman and followed the instructions (measure it up right, deflate, fill in, inflate, turn around the tyre, etc) but when i did have a puncture some time later, it didn't seal and i took it to the shop only to be told that they can't repair the tyre due to that stuff in it and i'd need a new tyre.

So i just stick to the old way now and just use a plug to seal any punctures.

It was the same brand i purchased off ebay (ultraseal) but somehow it didn't work for me.

It might have been due to the product being fake or me having used it improperly, but regardless of why it didn't work last time, I don't want to risk having to change a tyre again.

Out of curiousity though, do you reckon if i had it in the tyre that it would have sealed this rip that i pictured above? It's not a conventional hole so i thought the only way forward was a new tyre.

My new blue goop is supposedly water soluble, so it just washes out when the tyre needs to come off.

I think i've picked up a large industrial staple in my tyre already - still inflated

I tried to blow the tire up on Su's Yam vity about a year ago, I used the electric pump that came with the Fiat car, I didnt know it was connected to the anti puncture stuff, so when I turned it on I got about 2-3 seconds of white stuff going in her tire before i realised, so unplugged that and put air in, fast forward a few months and notice her tire needs air, we decided to do both scoots so went for free air at texaco station, couldnt put air into su's tire, tried for ages, had to call my local bike guy to see if we could pop in for him to have a look, he tried, no joy, took the valve out, no air came out, he shoved a paper clip up, nothing,puncture repair stuff had formed a thick seal over the valve !! in the end he had to clamp the tire to deflate it, clean all the puncture repair stuff out and then it worked. Wonder if that fiat stuff is crap ?? if you cant put air in the tire afterwards, I know its only a get u home thing, but sounds rubbish.
Maybe ultraseal is the way to go.

I did try one of these self sealing, permanantely in the tyre, goop things once. Every time i tried to check the tyre presssure i got a load of this stuff coming out of the valve, and got really fed up with it. When i changed the tyre i heaved a sigh of relief, and never used anything like that again.

That shouldn't have happened...you aren't aware of it until a puncture happens. Maybe the valve was loose?

The sealing compound may keep the pressure in a damaged tyre, when the tyre is then run at maximum speed it could let go big time. I stopped using it, when this was explained to me.

Hi Halfabusa. Sounds like a bummer. Sometimes you just have to accept things are a write off. For the tyre weld fluid I'd have to say you've been really unlucky and it'll be the Only time it ever happens tO you. Touch wood it has never happened to me in 25 yrs of riding bikes. Thankfully no one is shooting at you so it might not be needed

As for petrol stations charging 50 flippin pence, I agree, it's a disgrace. It should be a free compulsory service by every petrol station. On a bike especially it could be fatal having the wrong tyre pressures. Not being able to fix this because you don't have the cash or means to pay at that particular moment in time is just shocking.

It's not that 50p is unaffordable. The concept of having to pay for something which was provided free on all petrol stations up to a few years ago is a disgrace. I think these fuel stations are getting more and more greedy. However, not all blame lies with them either. My local shell used to provide a free pump but every few months some cnuts would rip the cord off or damage the pump, necessitating a repair. There are some real low lifes out there who mess with these things just for they can. Eventually the garage reverted to charging for the air.

Regarding the tyre pressures, the handbook on my tmax said 32psi front / 35psi rear and i always got that much in the tyres, but the guy who changed my tyres looked up and said bridgestone recommended 36/36 front and rear. I told him that sticking with the handbook for the bike surely must be the better option, and that not all bikes carry same weight, but he said bridgestone "specifically" mentioned this pressure for the tmax.

I'll try 36 each for a while and see how that feels. He might have a point. At the end of the day, the handbook is 9 years old (2003 model bike) whereas bridgestone information is accurate with the tyre build date.

Happend to me as well! And more than once.

I doubt that 1 to 4 psi would make much noticeable difference. I gotta be honest, I've always rounded it up to the nearst five anyway, (on all vehicles), on the grounds that the gauge is probably not that accurate, and you always lose a bit when you pull the hose off anyway, and not noticed any difference. There may well be a reduction in life becasue of it, and there could be a sticktion variance, but I can't say I ever felt it.
