hahaha Chris Harris is cool. Those AMG space savers actually look quite good but why 60 psi

I had my first experience of proper oversteer in the brab yesterday after the rain. Very unexpected but does put a smile on your face when it doesnt go tits up :-)

Thanks for that Alex......
And it is 'sort of' relevant.....
The notable thing being that the tyres were special rubber
(space savers do use a harder more resilient compound),
and that they were inflated to 60psi,  a higher pressure than
standard.
Methinks if it were driven at normal sensible road speeds that
it would have returned a far better fuel figure than normal on
a set-up like that, not that the tyres would last that long though.

Yes, spacesavers have to be inflated to a much higher pressure, perhaps the extra air makes these skinny tires able to cope with the weight of the car.

It looked like lots of fun, maybe future forfour owners will get together and have space-saver races with their RWD and all..

well that sort of blows the maths theory out of the water!!

here is the real world physics....

i need a set of those as my space saver does not fit over my wilwood brakes!!
