Do you provide materials to support TRWP research?

Using a Tire Industry Project (TIP) methodology, the U.S. Tire Manufacturers Association (USTMA) produces cryogenically milled tire tread (CMTT) and provides samples to researchers to advance scientific study on tire and road wear particles (TRWP).

CMTT is the product of a standardized and reproduceable laboratory process developed by TIP, that grinds (or mills) tire tread to simulate the tire particles that are generated by the friction between tires and road surfaces. CMTT is comprised of tiny pieces of the vulcanized rubber compound found in tire tread, but does not contain elements arising from pavement or any interactions with pavement.

Researchers can request samples via the USTMA website. Complementing the USTMA initiative, TIP has committed to make representative CMTT available for other regions by the end of 2022.
