for £20 you get some gunk in both tyres that is sold as being able to permanently fix a puncture up to 6mm in diameter that is good for 50k miles and 156mph.

I've not noticed a puncture yet (the gunk is bright green), but people I know who have, swear by it. For me, £20 was an easy purchase choice (£20 now or a puncture in the future and a 2 hour wait for the AA).

I used to race DH mountainbikes and tried a front tyre with that stuff in it. It made the wheel really heavy, massively increasing the rolling resistance. I also whacked it off a rock at and punctured.....

Granted, you won't be whacking it off a rock, but I imagine it will increase rolling resistance, and make the ride quality more 'rigid'

Interesting Greg, I used to ride trials (but not competitive, just in a hop about for a laugh way), keep meaning to rebuild the Azonic frame thats in the shed.....

well mate, if you need a hand building your hippity-hoppity bike, give me a shout....as long as you don't need me to service those old Magura HS 33s or HS11s hydraulic rim brakes you trials boys used to use <shudder>

Sanjoy,

A couple of guys on one of the mini boards tried something similar to this. They reckon that when the car sits overnight, all the gloop settles at the bottom of the rim and can take a few minutes driving till it's spread around again. This leaves you with a feeling of driving on square tyres till things sort themselves out.

May be ok on a heavy car/4x4 but would have thought this would be magnified on the elise or a bike.

Course they maybe overfilled the tyre.

There is a demo somewhere on t'internet with army trucks and land rovers drving over spikes etc with no ill effects, but this is at very slow speeds.

Derek (of very little help and possibly more confusion faction)

I also thought that if you put that crap in a tyre, when you change it it makes a right blo*dy mess of the rim and everything. (maybe that was different years ago. i used to use it on a quad bike and just kept filling it with more gunk every couple of weeks. i guess its probably improved since 1990 though)

I had this in my last car, Merc C200k, put it in the day I picked the car up, gave great piece of mind, however did not work at all. Still got a puncture. And as I replaced the tyres I never put it back in again. When you read about it, it sounds the dogs bo++ocks, however in practice....
