I disagree, blow your tyres up to a high pressure they will ballon in the middle of the tread due to the flexibility of the tread carcass. That's why when your tyres pressure's climb high the call will over heat the centre of the tyre more.
A RWD car will work the rear tyres harder than the front tyres, that's why I say remove more pressure from the rears, and to be 100% correct you may need to remove a little more from the left front as this will work harder than the right front.
I have worked in Motorsport for over 15 years so i do know a little about car set up.
Cool thanks for that How do you keep adjusting the pressure as you go along during the day? It was easy on a bike with only two tires but a car has four and the corners behave differently.
Would like to know what to keep on a 18" rays with P50's , I think it's probably going to be pretty cold on the track too.
