Thanks fellas,
But I fear I did not express well what I was
getting at.  I already know what it says on my
tires, but wondered about the *choice* of pressure
within that range, based on my driving plans.

Last winter in Mexico I was always getting grief
from Pemex attendants, who were shocked at the
45 lbs I was keeping in them!  One of them was so
horrified that, without even asking, he began letting
air out of my tires, explaining he feared my tires would
explode.  45 lbs, if I recall, is 10 lbs under the max
rating.

I have had a heart stopping day with my mail program
on the blink & my computer suffering repeated
"fatal exceptions" in sector 32, whatever that means!
Without this email I am toast, so if I should disappear
into the ether, that's why.
Fading fast,
Phaedra
