I run 250kPa/36psi all round on my RS wagon with OEM 225/40R18, which is what the placard recommends. If I have 3 passengers in the back I'd go 40psi at the back. Since I only got my car 2 months ago, and new tyres a month ago, I have no idea if that's a good setting or not, but I will be monitoring the tread level closely since I don't even know if the alignment is correct or not!
Is there any harm other than harsher ride in always running max pressure on OEM 18's even when car not fully loaded ie.
240 - 250kpa front
320 - 330kpa rear
