Abstract

A memory tire pressure gauge apparatus for use with race cars, comprising a pressure transducer, a control system and a display. The pressure transducer is for communicative connection to a tire of a race car. The control system is communicatively connected to the pressure transducer, receives tire pressure reading signals from the pressure transducer, and converts them to tire pressure display signals The control system has memory for storing a plurality of tire pressure reading signals. The display is communicatively connected to the control system, It indicates at least eight tire pressure readings simultaneously, the eight tire pressure readings corresponding to a relatively cold tire pressure reading with respect to an initial time and a relatively hot tire pressure reading with respect to a later time, after use of the tires, for each of four tires. The display further shows, simultaneously, four tire pressure change readings corresponding to changes caused by the use of each of the tires. The display receives tire pressure display signals from the control system. A method of gauging inflation pressure of a tire or other article is also disclosed.
