Re-watched the Harris "C63 on space savers" video last night, and it got me wondering what is the worst (best) tyre VS power ratio? ( http://www.youtube.com/watch?v=HPh90yNX-mY ), and what do we all have?

His claim of the C63 AMG being one of the best was based on:

480bhp / (255*2) wide tyres = 0.94bhp per MM.
368 lb/ft / (255*2) = 0.72 lb/ft per MM.

Only the driven wheels count. We should categorise super exotics separately from sub 100k cars.

My M3 has 358 / 255, so a lowly 0.7 bhp/MM. Something like a supercharged VX8 must be in with a good shout?

Edited for Mike.

Shouldn't that be 480/(255*2) = 0.94 bhp/mm as there are two driven wheels?
Lets not make this too complicated wink

I win

And it has 20inch rims

Bloody germans
That has to be unbeatable.

Do you even drift?
