Just read that a few of you had this done today, what's the score with this stuff then? Is it expensive?
StuF said:It is a water based compound that is pumped into the tyre through the valve.
There are fibres in the compound that react with any puncture and prevent any pressure loss.
Lasts the full life of the tyre.
The demonstration that was shown to me involved a tyre that had been holed more that 900 times and still kept pressure with no issues.
He basically hammered a 15mm wide spike into the tyre, elongated the hole by levering the spike about and removed it.
The tyre was then span around and instantly sealed when the resin got into the hole!
Impressive stuff to be honest
The guy doing at the show was charging £12.50 a tyre - considering the hassle of sorting a puncture out in europe its given me piece of mind!
He even did our trailer tyres for free!
I believe he will be doing a similar service at Dubs@TheCastle

Pirateringo said:I use something like this in all my bicycles, it allows me to run them with no inner tubes but if the puncture hole is too big, it will not seal. Pretty sure it will be same on a car tyre
Mr Brightside said:Well it's not actually 15mm really, a 15mm nail or bar does not actually leave a 15mm hole as the tyre stretches to a degree & then closed up afterwards, still leaves a hole, but not 15mm.

Granted the hole produced would be less than 15mm due to the makeup and elasticity of the rubber itself however I know this stuff is used on military vehicles in some pretty austere environments and will have got some of those guys out of a scrape or two I imagine. Despite the shrinkage and contraction of the rubber the spike was considerably bigger than any nail or screw I have seen stuck into a tyre - also bear in mind that the demonstration tyre had nearly 1000 (1 x thousand) of these holes in it and was keeping pressure with no issues.
But hey - it was only £50 to do the whole bus and I have spent considerably more on other things that are less safety conscious and much more shiny so if it doesn't live up-to expectations I don't feel that bad for giving it a go.
If you don't fancy having your tyres treated that's fair enough - and the likelihood of picking up a puncture is fairly low anyway, its only the trip to Europe that made up my mind and the 1000's of miles we will be doing over various surfaces.
