Abstract
A tire pressure monitoring system for a vehicle has been disclosed that can detect an excessive leakage rate of a tire. The system utilizes the starting pressure and starting temperature of a tire and the current pressure and current temperature of that tire with the time lapsed to determine the leakage rate of the tire. This leakage rate is compared to a leakage rate threshold. If the leakage rate is greater than the leakage rate threshold, an excessive leakage rate alert is generated.
