I just purchased a set of Pirelli Rosso Direzionale / Asimmetricos that I plan on using for AXs until I get another set of wheels. Does anyone have any experience running these tires and where to start the pressures front/rear.
Thanks

Are they 17" or 18" diameter? I've got 17"; (205/50 and 255/40) and run 30PSI cold front and 34PSI cold rear. On track I drop to 28PSI hot on the front and 34PSI hot at the rear. Tyre life is really good and grip from them is respectable.

I run 18 inch Assimetricos with 36 Psi in the fronts and 38 in the rear. 4000 miles later and they are wearing very evenly.

Thanks guys - they're 18".

Manual states for 18" :
front cold: 2.5 bar or 36.2 psi
rear cold : 3 bar or 43.5 psi
I wouldn't go below that. Under-inflating tyres is noooo good
