Running at less than "maximum" does not imply 
under inflated. No way, no how. Thinking that the 
maximum pressure stamped on the sidewall is the 
proper inflation pressure for any vehicle to 
which that tire might possible be mounted is 
simple ignorance. Repeating the error when it's 
pointed out is simple stupidity.

"Goodyear retailers should only recommend the 
vehicle manufacturer's correct air pressure as 
outlined on the Vehicle Tire Information Door 
Placard. In many cases, negative factors such as 
poor ride or irregular wear could occur if 
maximum air pressure is recommended to 
customers...No matter what the maximum pressure 
indicated on the sidewall, only recommend the air 
pressure as highlighted on the Vehicle Tire 
Information Door Placard. " -

"Many people believe that the proper or most 
suitable air pressure is the one molded on the 
sidewall of the tire (such as 35 psi or 44psi). 
This is not correct. Inflation pressure listed on 
the tire is the maximum pressure for the tire. 
Remember, the car, not the tire sidewalll 
markings, determines the correct inflation 
pressure. Check the vehicle placard for 
recommended tire pressure." -

"The number on the tire is the maximum allowable 
air pressure � not the recommended pressure for 
that tire when used on your vehicle." -

"Always inflate tires to the car manufacturer's 
recommendations as shown in the owner's manual. 
The label on the tire sidewall is not the normal 
running pressure." - http://www.wheels.ca/Tire%20Talk/article/244927

"automakers typically recommend an inflation 
pressure well below the tire's maximum air 
pressure. Follow the advice on the vehicle's 
placard." -
