What should these be?

I got some Octy vRS alloys on now...

I use 35 psi on the front and 33 psi on the rear, with Toyo Proxes T1-Rs.

I'm using 36psi front and 32psi rear with Khumo KU31's. Only had them on since Saturday though so it's too early to tell if they're correct!

Noticed that standard pressures on my OEM setup was scrubbing the edges of the Dunlop's (had the tracking checked to confirm this).

I use 35 front 30 rear on Pirelli P Zero's

I use 35 front and 32-33 rear.. I have falken fk452 though

Tyre pressures relate to the weight of the car. Changing the wheel/tyre size has virtually no effect on the overall weight, so run to standard pressures or whatever you prefer for specific handling choices.
