Abstract
A method is provided for recommending proper tire pressure using a tire pressure recommendation system having a processor. The method comprises obtaining a cold placard tire pressure (PPl) for a cold placard air temperature (TPl) and obtaining a measured outside air temperature (TOutside). The cold placard tire pressure (PPl), the cold placard air temperature (TPl) and the measured outside air temperature (TOutside) are entered into the tire pressure recommendation system. The recommended tire pressure (PRe) is then calculated with the processor for the measured outside air temperature (TOutside), the recommended tire pressure (PRe) being based upon the cold placard tire pressure (PPl).
