Just for the fun of it:
2005 Speedmaster owner's handbook, copyright 2004, part number 3853306, issue 1 - page 97
Front - Metzler ME33T:
30 lb solo
31 lb laden
Rear - Metzler ME880
Solo 31 lb
Laden 36 lb
This manual shows the America at the same pressures
I usually run 36 & 36
What's stamped on the tire is usually the maximum pressure allowed, and not necessarily the manufacturer's recommended pressure.
