Abstract

A tire pressure alert system suitable for use in a vehicle includes a vehicular tire pressure monitoring system and a telematic system of the vehicle. The telematic system of the vehicle is operable to wirelessly communicate between the vehicle and an external service provider external to the vehicle. The tire pressure monitoring system is operable to detect or determine or estimate a tire pressure in a tire mounted on a wheel of the vehicle and to communicate an output signal indicative of the tire pressure to the external service provider. The external service provider receives the output signal from the tire pressure monitoring system and processes the output signal and communicates an alert to the subject vehicle to alert the driver or occupant of the vehicle of a tire pressure condition in one or more of the vehicle'"'"'s tires.
