Gallardo tyre pressure

[Alpinestars]

Can someone confirm the tyre pressures on the Gallardo please. The manual states 2.2 bar on the front and 2.0 bar at the rear (P Zero Corsas). The label on the inside of the door says 43 ish psi, (approx 2.8 bar).

Cheers

With P Zero tyres fitted - 2.4 bar front 2.2 bar rear

With Corsa tyres fitted - 2.2 bar front 2.0 bar rear

Thanks, is people's experience that 2.2 and 2.0 are the best pressures using Corsas?

i know the above p0 figures are correct, as i checked mine this morning, but can anyone explain why the lighter end of the car requires higher pressures ?

If you go back to old money and psi, there are more sq inches in the larger rears so the pressure per sq inch is probably the same in the smaller fronts. You put 14 to 18 psi in a JCB rear tyre and it looks fine, put the same amount in a car tyre and it looks, and is, essentially flat.
