Tires and Technology: Getting the Most Out of Your Tires

This article points out that properly inflated tires on transit vehicles can extend the life of the tire treads by as much as 35 percent. Tire-related costs are the single greatest maintenance expense for a fleet, and improper tire inflation increase annual procurement costs by more than 10 percent. The author describes various automatic pressure monitoring systems, including options for internal sensors inside the tires, for sensors outside the tires, and RFID technology pressure readings using a sensor in the valve cap. Advantage PressurePro’s monitoring system uses a sensor that replaces the cap on the tire’s valve stem. The sensor continuously sends reading to a monitor inside the operator’s cab as well as to a maintenance office. The author also describes Fleet Specialties’ Tire Sentry Systems, which employs a handheld monitoring system that can get pressure readings while the vehicle is in the yard, as well as several other manufacturers’ systems. The article ends with a discussion on filling tires with nitrogen, which cannot leak through a tire as quickly as oxygen.
