The TPMS market is driven by legislation


Regulated market since Sep 2005, 100% penetration since Sep 2007 In 2010, first noticeable increase in aftermarket potential

New car platforms require TPMS from Nov 2012 All new cars require TPMS starting in Nov 2014 Direct measurement fulfills tighter specification requirements

Japan is expected to adapt EU legislation with 100% penetration in 2016 Adoption of technical specification from EU regulation expected

China: no regulation yet, actual status of technical specification for regulation is “pre-draft”

Beside a regulation-driven TPMS market, a potential TPMS market for trucks is seen
