Tire pressure alert system
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.
