Tyre pressures

Does anyone know what pressures my 19” OEM CSL tyres pressures should be for both front and back please?
 
It’s not too bad running on 19” as I haven’t lowered the car nor will I and it looks brilliant. I have had harsher 3 series running on RFT in the past than my car tuning on 19” wheels.
 
If you have RFT's fitted they run at a higher psi than normal tyres (+4-5 psi) otherwise yes around 32/34 (which I run on 18's) or similar appears right. You dont mention actual Tyre size which probably has more of an effect than Dia
If you run too high or low it will soon show up on treadwear so it pays to get it right.
 
Depends on tyre type and the stiffness of your tyre wall but I use Sport 4S for road use with 2.1 Bar front, 2.2 Bar rear - For general road use.
2.0 bar for track all round but that is with PS Cup 2s

Ditto, as this equates to Front of 30.5 & Rear 32 PSI - 35 psi IMO is way too high
