NHTSA May Exempt Trucks from Tire Monitoring Rule
Jul 26, 2001 12:00 PM
Medium and heavy trucks appear to have escaped a National Highway Traffic Safety Administration (NHTSA) proposal to require the installation of tire pressure monitoring systems, a NHTSA spokesman said today. The proposal targets new light trucks, buses, passenger cars, and multi-purpose passenger vehicles with ratings of 10,000 pounds or less.
Tim Hurd in the NHTSA public relations department said that the proposal does not include medium and heavy trucks; and that there has been no deliberation about them to date. He said carriers are more likely to be on top of tire pressure issues than the general public because of the expense and efficiency involved.
The proposal was published in the Federal Register Wednesday, July 18, and seeks comment on two alternative versions of the regulation. Only one version will be in the final rule, according to the NHTSA information.
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 percent 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 other 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 percent 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.
NHTSA estimates that 49 to 79 deaths and 6,585 to 10,635 injuries could be prevented each year if all vehicles were equipped with tire pressure monitoring systems. Consumers would benefit from increased fuel economy and longer tire wear. In addition, there would be benefits resulting from fewer crashes due to tire blowouts, immobilized vehicles, or poor vehicle handling from pressure loss and hydroplaning.
