Boxster tyre pressures?

[Frimley111R]

Ours runs on 265/35 ZR18 and 225/40 ZR18 but I can't work out what the pressures should be. Can anyone enlighten me please?

Look on the driver sill where the door latch is, all pressures should be there

Hmmm. They're not and besides, they are non std wheels

29psi front. 36psi rear.

If the tyre size are the same as stock then non-std wheels won't change pressure. I'd hazard a guess that the info in the driver's manual.

Ok, thanks

The pressures are shown on the inside of the fuel filler on mine. 29/36 is right for the 18"s anyway.

When you say they're non-standard, presumably they're Porsche alloys? They could be ordered from the factory with 18"s and those tyre sizes (front rims are 7.5" wide, rears 9", can't remember the offsets.
