Hi Guys

I have just returned from the Land Rover Owners International show, where I saw an interesting puncture preventative product that automatically repair puntures to tyres.

It is a liquid that you add to your tyres via the value before the tyre sustains a puncture. As the tyre rotates the product spreads evenly over the inside surface.

As soon as a puncture occurs fibres mixed with the liquid are forced into the gap and sealed with their contact with air, forming a permanent fix to the puncture.

It was demonstrated to me with a 4inch nail which was driven into an inflated tyre and then pulled out. You could here the air escape for half a second and then the tyre sealed. It doesnt work for side wall punctures but slows down the airloss, which would assist in an emergency stop on the motorway etc.

It would cost about £9 per tyre for the liquid.

I think it would be quite valuable in the desert as changing tyres and even changing the wheels in the heat never appealed to me.

They have a web site which also shows puncture preventative liquid that the military use (Armoseal) which can fix a 1 and a quarter inch hole in a tyre?? It also resists blasts from explosions so I would have thought it would be a useful addition to any overland trip

Speak with a guy called Peter Day
