Z4M Roadster Rear Tire Pressure

Oddly, the tire pressure door sticker on my 2008 says 30 lbs front and rear, while the Supplemental Booklet shows 30 lbs front and 32 lbs rear. Any insight? This is what happens when you have too much time on your hands ;~).

The only thing that I can think of is that the 32psi is for maximum loading. Note that the door jam or owner's manual pressure is only for the OE tire. The pressure would change if you move away from the OE tire, but that pressure is a good starting point for non-OE tires.
