The things slip'n'grip repeatedly, wears off the blinkin' tread.

You must know my mate Clive - he lives just round corner from me and drives a red car - I asked him once why he only ever goes out in wet - Duuuuh!! don't wear tyres out so quick!!

:-) :-)

I'dve thought it wore 'em out faster, especially if you happen to be "booting it"! Slewing around in this stuff is great fun, though.

I hope the driver of a Honda Jazz has gone off to Kwik Fit after spending the last 40 minutes trying to get out of a parking space - tyres spinning away, no doubt clutch burning. Morals of the story:

(i) Don't park facing uphill between two cars when the road is icy.
(ii) When you do get some road salt don't just put it under the wheels because as soon as you get going you are onto ice again and you will lose traction. I suggest spreading the road salt (he managed to get a bucket full) over a wider area and leave it for 5 minutes to work it's magic.

Interesting. Assuming no grip at all on top of a sheet of ice, surely you would lose less tread, as there would be no friction to remove it?

Watched a lorry driver trying to get out of a parking space during the last icy spell we had in County Durham.

He had the driven wheels spinning and smoke coming from the tyres, but still no forward movement.

Surprising, I would have thought the heat from the smoking tyres would melt the ice and giver some grip, but it didn't seem to.

I think that it was steam you saw coming off those tyres.
Spinning tyres melt the ice and it is actually the water produced that reduces traction to nowt as it produces a film between the tyre and the ice.
So, melted ice is more of a problem than a solution.

I have had tyres smoking on snow/ice. I have no idea how it can cause enough heat to smoke and not move.

Some friction, of course, but not much. The wear comes from slip, i.e. on ice/snow, then sudden grip, i.e. on tarmac.
