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 (TOutide) 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).
Claims20
A method for recommending proper tire pressure using a tire pressure recommendation system having a processor, comprising:
- obtaining a cold placard tire pressure (PPl) for a cold placard air temperature (TPl);
- obtaining a measured outside air temperature (TOutside);
- entering the cold placard tire pressure (PPl), the cold placard air temperature (TPl) and the measured outside air temperature (TOutside) into the tire pressure recommendation system;
- and
- calculating a recommended tire pressure (PRe) with the processor for the measured outside air temperature (TOutside), the recommended tire pressure (PRe) being based upon the cold placard tire pressure (PPl).
A method for recommending proper tire pressure using a tire pressure recommendation system having a processor, comprising:
- obtaining a cold placard tire pressure (PPl) for a cold placard air temperature (TPl);
- obtaining a measured current tire temperature (TTire);
- entering the cold placard tire pressure (PPl), the cold placard air temperature (TPl) and the measured current tire temperature (TTire) into the tire pressure recommendation system;
- and
- calculating a recommended tire pressure (PRe) with the processor for the current tire temperature (TTire), the recommended tire pressure (PRe) being based upon the cold placard tire pressure (PPl).
A tire pressure recommendation system, comprising:
- a memory element for storing data indicative of a cold placard tire pressure for a cold placard air temperature;
- a thermometer capable of measuring outside air temperature near the tire;
- processing logic configured to generate a recommended tire pressure for the measured outside air temperature, the recommended tire pressure being based upon the cold placard tire pressure;
- and
- a display for communicating the recommended tire pressure.
