Tire Pressure Monitoring Systems (TPMS)

Tire Pressure Monitoring Systems (TPMS) are mandated in many countries due to their impact to inform drivers on vehicle safety and fuel efficiency. It has been shown that under-inflated tires can lead to less control of the vehicle on the road and higher probability of vehicle rollover. Additionally, under inflated tires can drastically reduce the fuel efficiency of the vehicle leading to higher levels of emissions. As the world market leader in TPMS pressure sensors, SMI has a variety of solutions that can enable accurate pressure readings in this harsh environment.

Legislation in USA (2007) requires all new cars to be equipped with TPMS.

2013 – Europe started with 100% compliance in 2014.
2014 – South Korea confirmed legislation.
2017 – Japan intends to legislate.
2018 – China intends to legislate.
2019 – India intends to legislate.
