Tire Technology in brief: Tire Build-Up process


Reduced CO2 emissions– 20% CO2 reduction for

passenger cars in Europe mandated by 2021 (vs. 2015)

– 95 g CO2 / km from 2020+

Tire Labelling– 20-30% of vehicle fuel

consumption related to rolling resistance of tires

– Tire Label adaptions worldwide– EU: adjustments 2019?

Europe: mandatory since 2012

Japan: voluntary since 2010

Korea: mandatory since 2012

China:voluntary 2017, mandatory expected 2018…19

Legislation & Labelling


The Mobility revolution: E-Mobility & Autonomous Vehicles

The Tire of the Future– Even more durable than current– Tall and skinny shape– Sensor technology– No speed rating– Riding comfort and NVH– Lower rolling resistance– Labelled for compatibility– Faster development cycle/Speed to market
