Research into Tire and Road Wear Particles (TRWP)

Tire and road wear particles (TRWP) are tiny debris produced when tires are used on the road.

Generated by the friction between tires and the road surface, TRWP are a mixture of tire tread material and road pavement material.

The Tire Industry Project has been supporting research into tire and road wear particles since 2005. In 2020, to mark the 15th Anniversary of the Tire Industry Project, TIP made most of its peer reviewed research available free of charge, and will aim to do so for all future studies into TRWP. It has not been possible to make some of the earlier TIP studies open access - copies of these studies can be requested from the study authors as indicated below.
