Abstract

The National Highway Traffic Safety Administration is seeking comments on two alternatives of a regulation that would require the installation of tire pressure monitoring systems in new passenger cars, light trucks, buses and multipurpose passenger vehicles with gross vehicle ratings of 10,000 pounds or less. The tire pressure monitoring system would warn the driver when a vehicle has a significantly under-inflated tire. One alternative would require that the driver be warned when the pressure in one or more tires, up to a total of four tires, has fallen to 20% or more below the vehicle manufacturer's recommended cold inflation pressure for the vehicle's tires, or a minimum level of pressure to be specified in the new standard, whichever is higher. The second alternative would require that the driver be warned when tire pressure in one or more tires, up to a total of three tires, has fallen to 25% or more below the vehicle manufacturer's recommended cold inflation pressure for the vehicle's tires, or a minimum level of pressure to be specified in the new standard, whichever is higher. Potential benefits of tire pressure monitoring systems include fewer accidents, injuries and fatalities; increased fuel economy; and longer tire wear.
