i beg to strongly differ ... always go by the TIRE itself, not a
10-year old sticker on your bus!!!!
the tire has stamped into the sidewall what its Max Pressure is ...
you can run that until you decide that it may be too stiff a ride,
then start lowering the pressure (on both sides of the bus!) to find a
comfort level for your ride. i'd suggest NOT going below 80 percent of
that Max Pressure, cause then you'll have an underinflated tire that
could heat up and damage itself. and always remember that if you lower
the pressure, you also lower the Max Load that the tire can carry!!!
