National Highway Traffic Safety Administration: Quick Pressure™ product meets and exceeds the NHTSA rule 49 CFR Parts 571 and 585
The NHTSA, the Transportation Department agency responsible for vehicle safety, estimates that monitoring tire pressure could prevent over 10,000 injuries and countless deaths.
The government has proposed a new rule mandating that all vehicles made after November 2003 have systems to warn drivers about low tire pressure. This is in response to the recall of 6.5 million Firestone tires that occurred in August of 2000.
Department of Transportation (DOT) studies have shown that 27 percent of cars and 33 percent of sport utility vehicles and light trucks have at least one under-inflated tire by eight pounds per square inch or more. Under- inflated tires have a greater rolling resistance than properly inflated tires and, therefore, consume more fuel. The DOT estimates that under-inflated tires cause consumers to unnecessarily purchase up to 4 million gallons of gasoline per day. By warning drivers when their tires are under inflated, tire pressure monitors(TPM) will save consumers’ money by improving their fuel economy, as well as emitting less CO2 emissions into the atmosphere.

There are something, you should do:
(1) Check tire pressure at least once a month and before going on long trips. Since temperature affects tire pressure, it is best to check tires when they are cold, i.e. have not been driven on for at least three hours.
(2) Fill your tires with the pressure recommended on the tire label, located on the driver’s door frame, sill or edge.
(3) If you have any questions about your tires or maintenance, check your owner’s manual or consult your dealer.
