The tire pressure monitoring system (TPMS) sensors industry is expected to grow by 17% in 2017 as ever more countries see the importance of TPMS sensors. With a production volume of more than 300 million so far, Schrader is a key player in the worldwide TPMS market. Total demand is expected to reach 55 million vehicle sets. China might hold the biggest promise here, too. At the same time, the total market share of indirect systems (systems without their own sensors) is expected to shrink.
