interersting fact i just heard on the f1 practice!
standard truck tyre 10% rubber. according to anthony davidson on f1 show. i quite like his commentry actually. seems to know his onions!

I really enjoyed Anthony Davidson comentary when he was on 5 and the red button,its just a bloody shame
he has turned to the dark side !!!!!!

So, what are they made from?
So far you have given us HALF an interesting fact.

this suggest they do? http://formula1.about.com/od/tires/ss/bridgestone.htm
unless davidson is talking about the difference between natural and synthetic?

He said he got the info from a visit to the Michelin factory in china. And didn't know what it was made from. He just said 0% rubber

Must be referring to natural rubber (i.e. that comes out of trees)

that link is for bridgestone tyers. 2012 f1 tyres are pirelli i think
and is 5 years old

please don't say its carbon fibre or all the chavs will start putting CF stickers on the side of their tyres next.

most tyres are made from styrene butadiene rubber , which is synthetic

Ah, recycled old wellingtons.
Or, as they are made in China, perhaps that should be flip-flops.
