Presentation

Advances in regulatory tire abrasion testing with the vehicle method

ETRTO has been working since 2018 on the design of a vehicle-based tire abrasion rate index test method for consumer tires as a contribution to the regulatory evolution under the framework of a task force at the United Nations WP.29. After improvements introduced in 2023, a second test campaign was performed. In addition, the measurement of 180 tires selected to obtain a state of the art of the UN consumer tires market gives a statistical view of abrasion performance. The development of abrasion index test methods for van and heavy-duty truck tires is also in progress. These developments and results are presented.
