z4 m roadster stock tire pressure

imom · 11-08-2009, 08:33 PM

Hi, I just got my m roadster 3 weeks ago. The manual says 30 psi front and 32 psi for rear. When I got my car, it had about 36psi all around. The label on the side of the door says 30 psi all around. When I took it to the dealer for service, they adjusted all tires to be around 37 psi (cold readings). What's the recommended tire pressure (cold reading) for the stock continental M wheels? I appreciate members letting me know.

I did use search and gone through the first 2 pages worth of searches...didn't see anything. Thanks.

Just got back from Inspection I, they adjusted the pressure back to 30psi cold all around, just like its supposed to be - i would guess thats the official recommendation for general all-purpose use.

My Z4MC door frame sticker shows 30F/32R cold. That's what I stick to and it handles great. For sure anything more than that is bad news unless you like less grip and squealing tires.

Thank you for the replies...I also talked to the service advisers...he didn't recommend 37PSI...I guess the tech's gauges are way off or they were lazy. I'll change it back to 30/30 as posted on the door sticker. Amazing how different the tire pressure than run flats on my old Z43.0SI.
