Sometimes the tire will say how much air is needed for daily driving on the tire near the tire size or close o the rim. __________________ Why do ideas seem good when you think but arent when they are implemented? ~*Lost Soul of Chevy*~

Even a "daily driving" recommendation from the tire doesn't help me determine the proper pressure under different load (weight) conditions.

It would be great if the tire manufacturer would provide such information as the proper inflation of the tires given the vehicle's total weight. But that would mean they'd have to get it right.

The tire pressure listed on the side of the tire is to be considered the maximum inflation(80 psi. in this case). You should stick with the truck's manufactuer on the optimum tire pressure because too much pressure can cause premature steering component failure as well as bearings ride and handling problems. The tire kinda acts like a shock absorber or a buffer between the road and your truck and having too low a pressure can end up causing damage to the tire, the rim handling problems and/or poor fuel economy. Tire maufactuers cannot supply inflation ratings other that maximums because of different applications.
