Hi Gio.
Front wheels: 33 psi and 37 psi
Rear wheels : 36 psi and 40 psi.
The list in my car gives the pressure both for summer tires and M+S tires.
I suppose the higher pressures are for summer tires ??
If any doubt, I can send a picture of the label in my car.
My car is a european model TT 2+2 left hand drive.
Regards, Michael
