Does anyone know what the surface operating temps of R888's in GG compound should be? At the mo it's just for info before setting the pressures at silverstone.

ATB Dan.

Doesn't really answer your question I know, but I'm finding that 16-18 psi is giving me a fairly even tread wear cross the tyre. (Using 195-50-15).

This is serious sounding stuff you're into here though - you going for the lap record or summat.....

if you manage to get 55-60 °c, it means you are fast!
toyo reckon 80°c, but it's unachievable in our light cars.
try diferent pressure set up and be sure your tyres warm equaly and enjoy!
cheers
