Default What tire pressure are you running?

I got my car back today from the dealer and the paper work says they adjusted the tire pressure to 34 front and 38 rear. This seems wrong as the manual, door sticker and previous service reports all list 36psi all around.

What is going on? Technician error?

36 x 4 should be fine on the stock set up... And your right, it's on the door..!

I run 36 & 38 on my non stock set up..

40 all around. The dealer just adjusted mine to 33 in the front and 35 rear and the car feels weird...harder to turn. Most dealer techs are clueless.

The Verdict: Technician error (duh)
correct pressure 36psi.
I have now set all tires to 38psi cold. Max for my tire is 51psi.

For those of you with PS2s... what do you guys run?

Door says high 30s but tire rack says max PSI for the pS2 is 50??

Right now I have 36 all around.

^^ If you want your tires to wear normally..

Any where between 35 and 38 will be fine.

50 PSI is a max load rating - not the actual PSI.

Has anybody else noticed in the manual that if you live in a country with speed limits above 100mph, that they reccomend to add an additional 9 psi. (ie. 45 psi)??? If I ROUTINELY drive over 100mph for long periods of time, is this what I should be inflating my tires too??

Cold pressure at the track is 32 psi on all four. Normal driving is recommended 36 psi after playing with it up and down a bit. Stock works best for street duty.
