I'm not sure exactly what pressures you should be running mate, but my point was that you can fiddle with tyre pressures in the same way you can fiddle with suspension settings, and they don't need to be the same all round.
Purely as an example, check out our tyre pressures when we were running the Corolla:
Eastern Creek:
RF: 17psi LF: 20psi RR: 19psi LR: 19psi
Oran Park South
RF: 19psi LF: 20psi RR: 21psi LR: 21psi
Oran Park GP
RF: 19psi LF: 20psi RR: 20psi LR: 20psi
Wakefield Park
RF: 20psi LF: 20psi RR: 21psi LR: 21psi
They were cold starting pressures, and obviously they'll be different to yours because they were slicks on a car that only weighed 730kg, but you can see that for each circuit they were different, some front to rear, some left to right.
No fixed answer of course, and the numbers only appeared after experimenting for ages. And then it all changes depending on whether it is a hot day or a cold day...
But for your car you may be able to get better steering response by altering the pressures from front to rear. Having a good quality, accurate gauge also helps.
