Recommended psi verses Max psi.

I read the forums fixed post, "Tire tech" by Luke@tirerack. It was good reading, however, it did not quite answer a question that I have had for 20 years regarding max tire pressure.

Regarding tire inflation technique, the forum post stated, '....recommended tire pressure...cold...'. The problem is that the tires all say, "max tire pressure", instead of 'recommended'. Here's my question. If a tire says 'max 35 psi' and it is 70 degrees cold, parked overnight, etc, and by late afternoon it will be 90 degrees, then; should I fill the tire to 33 psi, so that I do not exceed the max psi later on when the tire heats up?

I have always underinflated my tires by 3 psi from the 'max psi' printed on the tire, in a calculated effort to not exceed the 'max psi' as the tire heats up.
