road or track?

Do you brake hard??

Do you drive smoothly or are you quite abrupt with the wheel???

I would run 30 all round then and then check wear on the tyres. If the centres are wearing unevenly too much pressure, and visa-versa

Pressures aren\'t critical to have tolerances of 1psi with the way you are driving. It is down to feel.

Usually mine are 28 front and 30 rear but after some spirited driving they are more like 32 and 34, so dependent of driving style.

For a lap of the ring I\'d have 24-26 front and 26-28 rear when cold.
