Potential benefits of Triple-A tyres in the Netherlands (TNO, Netherlands, and M+P)
Potential benefits of Triple-A tyres in the Netherlands
“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.

Tyre noise limits of EC/661/2009 and ECE R117: Evaluation based on sold tyres in the Netherlands (Netherlands and M+P)
Tyre noise limits of EC/661/2009 and ECE R117: Evaluation based on sold tyres in the Netherlands
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”.
GRB-60-12
Shifts in tyre sound levels between 2007 and 2013 (M+P and Netherlands)
Shifts in tyre sound levels between 2007 and 2013
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).
GRB-60-14/Rev.1
Triple-A tyres – benefits for environment, noise, safety and economy (Netherlands, TNO, and M+P)
Triple-A tyres – benefits for environment, noise, safety and economy
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 presentation reviews data collected on the advantages demonstrated by such triple-A tyres.
GRB/2014/8
Proposal for Supplement 7 to the 02 series of amendments to Regulation No. 117 (ETRTO and Russia)
Proposal for Supplement 7 to the 02 series of amendments to Regulation No. 117
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.
