Silent TPMS - Tyre Pressure Management System

TPMS monitors the air pressure and temperature inside pneumatic tyres on various types of vehicles. It reports tyre pressure and temperature data in real time to the driver of the vehicle, via a gauge, a pictogram display, or a simple low-pressure warning light. There are two types – direct (dTPMS) and indirect (iTPMS), installed in the OEM (factory) level as well as an aftermarket solution. 

The prime social objective of TPMS is to help avoid traffic accidents and reduce pollution levels by a better use of fuel. From 2008 in the USA, and from 2012 in the EU all new passenger car models released must be equipped with a TPMS; and from November 2014 all new passenger cars sold in the EU must be equipped with a TPMS. Commercial vehicles do not, as yet, require TPMS.

Silent TPMS starts with a unique identity for the tyre which serves as a Certificate of Provenance that lets people track and trace its physical location at a given moment in time throughout the supply chain, from manufacture to distribution, warehousing, usage, repair, retread and recycle at the end of its usable life. Paired with pressure and temperatue sensors, digital tracing and sensing provide a low cost route to improve supplier efficiencies and integrate with a whole ecosystem of management systems.


What is driving demand?

  • The connectability of tags, sensors and controls (Internet of Things)
  • Falling cost of tags and sensors, rise of the smartphone, ubiquity of big data
  • Manage tyres properly to increase service life by up to 30%
  • Reduce legal liabilities (20% of truck accidents caused by bad tyres)
  • Reduce premature damage (€90 per tyre according to Bridgestone’s research) 
  • Squeeze value out of the tyre through its life to recycling (the Circular Economy)
  • The transformation of tyre makers, OEMs and distributors into service companies
  • Public policy regarding health, safety, fuel economy, emissions, climate change
  • Autonomous driving, especially for truck fleets.
