On my stock wheels/tires (18"), I'm using the recommended 32 PSI all around.

I have 17" wheels with Pirelli 210 Snow Sports that I use in winter months. I'm having trouble finding recommended PSIs on the web.

I have faith in you guys though... what are you using?

 

The manual says for winter tires to put 4.6 psi above door stickers recommendation.

 

or up to the max pressure of the tires. In my case, my M3's state 35PSI.

I thought you weren't supposed to put up to the max pressure of the tire because when the tire warms up and the pressure expands you will be over the max pressure indicated on the tire which is no good. But then again if your tires says max pressure is 35PSI you will be over by the manuals recommendation of 4.6 over the door sticker which is 32 or total 36.6. Interesting situation.

 

I think the max pressure on your tires is the max cold pressure.

I replyed above based on this thread:

https://www.rx8club.com/canada-forum-35/winter-tire-pressure-45062/

which quoted the entire manual:

"Use snow tires on all four wheels.
Don’t go faster than 120 km/h (75 mph).
Inflate snow tires 30 kPa (0.3 kgf/cm2,
4.3 psi) more than recommended on the
tire pressure label (driver’s door), but
never more than the maximum cold-tire
pressure shown on the tires."
