Tire pressure

I had issues in my 335i that the winter tires would wear very quickly on the wheel centerline when inflated to the recommended pressure.

Since then with my M3 I have been inflating all four winter tires to 34 psi.

What is the risk to not having enough pressure and how does that change from being the only person in the car to a loaded vehicle?

The dealership said to run the pressure lower but didn\'t say how low or what safety issues there may be. I understand fuel economy will go down, but I want the best grip and tire wear with my Dunlop Sport 3D winter tires.
