USA
The use of direct TPM in vehicles in the USA was mandated in 2000 by the Transportation Recall Enhancement, Accountability and Documentation Act (or TREAD). This states that the driver of a vehicle must be warned of under inflation by 25%.[15] The warning is displayed to the driver in line with 49 CFR Part 571 Federal Motor Vehicle Safety Standards (FMVSS). The minimum requirement for the warning is in the form of a simple lit symbol on the dashboard, and this is often augmented by the display of a graphic of the car showing the wheel position to which the warning light corresponds. All new model year 2008 light vehicles shall have a TPMS (direct or indirect) fitted which is capable of detecting when one or more of the vehicle's tires, up to all four tires, is 25% or more below the manufacturer's recommended inflation pressure (placard pressure) or a minimum activation pressure specified in the standard, whichever is higher.
EU and Far East
European Union (EU) and Far East legislators are looking at TPMS as a way of reducing CO2 emissions, and are presently (as at January 2009) considering compulsory tire pressure monitoring systems from this environmental stance. Starting in November 2012, all new models of passenger cars must be equipped, in E.U., with a TPMS.
