Profile: Fleet Specialties Co. is engaged in the manufacture of tire sentry systems. We offer advanced tire pressure monitoring systems for all classes of trucks, buses, recreational vehicles and trailers. The Tire Sentry® wheel sensors continuously monitor tire pressure and will only activate the transmitter when a loss of tire pressure (or under-inflated tire), is detected. Tire Sentry sensors use 2 standard watch batteries that can last up to 3 years, and are easily replaced. Tire Sentry pressure sensors fit onto the existing tire valve-stems, or may be installed on optional dedicated valve stems on the opposite side of the wheel. All sensors are coded specifically for the vehicle or trailer. This enables wheel sensors to be vehicle specific or fleet specific as necessary for individual operation, or fleet operation. Our tire pressure monitoring systems automatically monitors for low tire pressure, thus reducing the need for manual pressure checks. It helps to extend useful tire life of both new and retread tires & reduce road service calls. It also helps to increase fuel efficiency.
