Patent ID: 7216532

Claim:
A method for recommending proper tire pressure using a tire pressure recommendation system having a processor, comprising: obtaining a cold placard tire pressure (P Pl ) for a cold placard air temperature (T Pl ); obtaining a measured outside air temperature (T Outside ); entering the cold placard tire pressure (P Pl ), the cold placard air temperature (T Pl ) and the measured outside air temperature (T Outside ) into the tire pressure recommendation system; and calculating a recommended tire pressure (P Re ) with the processor for the measured outside air temperature (T Outside ), the recommended tire pressure (P Re ) being based upon the cold placard tire pressure (P Pl ); wherein the recommended tire pressure (P Re ) is: P Re = P Pl + [ T Outside - T Pl 5.56 ⁢ ° ⁢ ⁢ C . / ⁢ psi ] .
