The dangers of low tire pressure became more prominent following the Firestone and Ford tire controversy which led to the passing of the TREAD Act and the codification of FMVSS 138.
The standard is to warn drivers of significant under-inflation of tires and the resulting safety problems of low tire pressure.[1]
This standard requires a tire-pressure monitoring system (TPMS) to be installed in all new passenger cars, multipurpose passenger vehicles, trucks, and buses that have a gross vehicle weight rating (GVWR) of 4,536 kg (10,000 lbs.) or less, except those vehicles with dual wheels on an axle. The final rule requires that the driver be given a warning when tire pressure is 25 percent or more below the vehicle manufacturer's recommended cold tire inflation pressure (placard pressure) for one to four tires.[2]
The standard became effective October 7, 2005 however voluntary compliance was allowed prior to this date.
