Larry,
Feel is important... to a point... and that is the minimum allowable tire
pressure. If you want to know that number the tire dealer should be able to
provide that information. I had some tires on my SUV and it felt too
stiff.... the dealer brought up the information on his computer (or called
the tire distributor, I forget which) and he gave me a chart the listed tire
pressures for the weight of my vehicle.... this method of determining
minimum pressure may be more accurate that Joel's suggestion of 80% of
maximum pressure listed on the tire's side wall.
