Lowest tire pressure

What is the lowest pressure I could use in my M3 tires, so as to drive both around the city / on the highway at high speeds?

>> 19" stock wheels and no run-flat tires

>> Tire pressure recomended by the factory is 39.7

Thank you.

Where did you get 39.7-thats not on the door. 35 all corners for non-autobahn speeds and non-load. Higher than that for a loaded car or sustianed 100 mph plus speeds.

Thereīs a black sticker on the drivers's door jam listing several pressure values. 39.7 is the recommended tire pressure for non-load and two people in the car.

Maybe itīs different in this country.
