For the selection of optimized EV tyres Continental Reifen Deutschland delivers carved prototype tyres to Université Gustave Eiffel for testing on the LIFE E-VIA prototypal test surfaces in Nantes: Université Gustave Eiffel performs constant speed and accelerated pass-by noise measurements according to UNECE R51.03. These tyres aim at optimizing the balance of exterior noise performance and other tyre performances (e.g. rolling resistance, grip) for EV vehicles.
