TPMS Legislation - In 2000 Firestone recalled 6.5 million Tyres due to tread separation on Ford vehicles. This prompted President Clinton to sign the first version of the TREAD Act which required Tyre Pressure Warning Systems to be implemented on Model Year 2004 automobiles. These were to include all passenger vehicles and light trucks with GWVR of 10,000 lbs and less.
A debate continued over the language of the ruling up to 2005 when the final rule was established on April 8 2005.
NHTSA have stipulated that for 2008 all newly manufactured or imported US cars will be fitted with TPMS systems most of which use 'direct' sensors which are either part of the valve stem or banded to the wheel. These sensors transmit their own ID along with their pressure, temperature and other data to the vehicle ECU and the legislation defines the designated dash mounted warnings for the driver when a Tyre is under inflated/leaking etc.
So all vehicles described in the ruling, made or sold in the US must have Tyre Pressure Monitoring Systems by Model Year 2008. This ruling prompted significant plant system and aftermarket work for Bartec USA. The ruling meant that every time you need to rotate Tyres, replace a faulty sensor, change to Winter Tyres or Custom wheels then the ECU needs to be reprogrammed with the new ID and their position on the vehicle. This resulted in a surge in demand for the company's dealer tool products. Click here for more information on the US TPMS Legislation.
