Didnt realise this would cause such a debate!
I inflated my tyres to 36 front and 37rear just after i left home,and have to say that they were at 33F+34R before. After a few laps,i felt the car wasnt right,so checked the pressures,and they were over 40 all round,so dropped them to 35 all round,and the car felt so much better,and more planted,especially round the fast corners. I was understeering before,and after the pressure drop,it just gripped and felt alot better.
