“Quick scan” study prepared for the Dutch Ministry of Infrastructure and Environment to evaluate the potential of “triple A” tyres to improve vehicle safety, noise emssions, fuel consumption, and CO2 emissions. Tyres in the EU are labeled to convey information on their energy efficiency, safety, and noise performance. Triple A refers to tyres receiving the highest ratings across these three criteria.

This leaflet gives a short introduction for those who wants to explore the benefits and common pitfalls of silent road surfaces in urban situations.

Memorandum to the Netherlands Ministry of Infrastructure and the Environment in response to its request for research into

• the effect of the present tyre Regulations on the exterior noise levels of tyres
• comparison of the tyre noise levels in the present distribution with the limit values defined in the tyre Regulations
• definition of the levels of “present-day technology and ambitious technology on base of the distribution of levels found in the present tyre population”.

Review of research program that quantified differences in tire noise levels between the tire population on sale before and after revision of tire regulation in 2009 (Regulation (EC) No 1222/2009).

Proposal to introduce a “Deceleration Calculator” (dω/dt) for use in the UN R117 test procedures. This procedure was developed by Russia and validated by an ad hoc group (including NAMI, UTAC, and ETRTO).

At the 58th GRB session, the expert from ETRTO introduced GRB-58-02, proposing new time measurement accuracy for instrumentation involved in the rolling resistance method (Annex 6 of the UN Regulation). The expert from the Russian Federation introduced GRB-58-13, arguing that this change of accuracy was not needed for Annex 6. This present revised proposal has been prepared the ETRTO and approved by Russia.
