The driver door jamb also provides BMW recommended air pressure.

39 (2.7 bar) is what my door says. E90 but still a bit odd its higher as close to same exact weight. Also, seems like the door jamb spec quite a bit lower in the US?
Anyhow, around 39 I think is fine and my new PSS could even live with a tad more without going too stiff.

Cheers

I was at the track last month. I was parked with next to two other E92 M3s. we all had different tire pressure ratings listed on the door. All the cars were delivered with same Conti tires. Model years of the cars were the only difference. there must be a reason.

mine says 33/35 I run 34/36 most of the time.

My '11 zcp says front 35, rear 36

An additional sticker indicates alternate tire pressures for speeds exceeding 100 mph - front 41, rear 44

I'm running front 37, rear 39 for now

Ah, just remembered there are even at least 3 different set of springs depending on options/weight. So guess it makes sense with individual pressure as well.
Mines for instance is pretty fully loaded so a heavy one hence 39psi - makes sense?

Tire pressure depends on whether you want to dial in/out oversteer or understeer.

My car oversteers so I tend to run the rear pretty low...like 28-30psi. Fronts low-mid 30's.

Just remember the lower the tire pressure in the rear the better the grip.
