Tyre category definitions and requirements for tyre use on roads under winter conditions
Document Title: Tyre category definitions and requirements for tyre use on roads under winter conditions
|
Document Reference Number: GRRF-83-05
|
Description: Germany reviews problems with applying UN specifications for the marking of winter tyres, covering disparities in definitions and performance requirements across the tyre regulations (UN R30, R54, R75, R106, R108, R109 and R117). Therefore, Germany proposes that GRRF work to resolve these disparities and offers two possible solutions: 1) Introduce the definition of "Snow tyre for use in severe snow conditions” and the related performance and marking requirements established under UN R109 and R117 into UN R30, R54, R75, R108, and (possibly) R106; 2) Amending UN R117 to extend the scope of its snow performance criteria to additional tyre classes and categories, such as special tyres (POR, MPT), all terrain (AT) tyres, and retreaded tyres for passenger cars.

48. The expert from Germany introduced GRRF-83-05 looking for guidance on the possibility to develop snow tyre provisions for all tyres and vehicles categories as it was already existing for snow tyres of category C1, C2 and C3 for vehicles categories M and N by amending all relevant Regulations or by amending the scope of Regulation No. 117. The expert from Japan and the Russian Federation volunteered to contribute to the work item proposed by Germany. GRRF requested to add an agenda item dedicated to snow tyres on the agenda.

24. The expert from the Netherlands presented a project on labelling road surfaces (GRB-65-20, GRB-65-21, GRB-65-22 and Add.1) based on four criteria: skid resistance, noise reduction, rolling resistance and lifespan. According to the expert, labelling road surfaces could contribute to road safety, public health, sustainability and economics. GRB noted that the scope of the 1958 and the 1998 Agreements (wheeled vehicles, equipment and parts thereof) does not cover road surfaces and, therefore, no legally binding regulatory decisions could be taken at the WP.29, AC.1 or AC.3 levels. This does not preclude, however, adopting a Recommendation or Resolution on the issue. GRB welcomed the presentation and reiterated the importance of a holistic approach to sound emissions in the system ‘tyre-road surface’. Finally, GRB agreed to keep this item on the agenda and looked forward to new presentations on activities conducted at the national level in the field of road surfaces.

23. The expert from the Netherlands introduced a summary of various initiatives to reduce noise emissions from road traffic (GRB-65-27) which addressed different sources of noise (road surfaces, tyres and powertrain). He reiterated the benefits of better tyres and maintaining the correct tyre pressure for road safety and fuel efficiency. Finally, he pointed out that excessive drivers’ reliance on the Tyre Pressure Monitoring System (TPMS) might be counter-productive. GRB thanked the Dutch expert and noted that these initiatives had already been considered by GRB on various occasions and that some of them fall under the competence of other bodies. For example, the Chair indicated that tyre labelling and TPMS should be addressed by, respectively, EU and the WP.29 Working Party on Braking and Running Gear (GRRF). The Chair also recalled the GRB position that it would premature to tighten the current tyre noise limits in Regulation No. 117.

15. The expert from the Netherlands provided an overview of their research projects on tyres and proposed a two-stage tightening of the tyre limits for the rolling resistance coefficient, wet grip index and rolling sound emissions (GRB-66-01 and Add.1, GRB-66-03). He also highlighted the importance of keeping the correct tyre pressure for fuel efficiency and pointed out shortcomings of the EU system for labelling tyres.
16. The expert from ETRTO was of the view that the selections of tyres in the Dutch studies was not representative enough for the European market and volunteered to submit to the next GRB session a more comprehensive analysis. The expert from OICA supported the ETRTO view and proposal. He further introduced the results of a recent study of C1 summer tyres (GRB-66-22) according to which no tyre was performing equally well in rolling sound and handling. The expert from Germany acknowledged the progress achieved in rolling sound and pointed out the need to find a compromise for the three tyre parameters in question. He also agreed that the tyre labelling system would need to be improved.

He also agreed that the tyre labelling system would need to be improved.
17. The Chair was of the view that amending the limit values in Regulation No. 117 would first require a general agreement of all stakeholders, including the Working Party on Brakes and Running Gear (GRRF). Finally, GRB decided to continue the discussion at the next session.
Working Party on Noise | Session 67 | 24-26

15. The expert from ETRTO assessed the latest proposals from the Netherlands for stricter tyre noise limits, as presented at the sixty-sixth session of GRB (GRB-67-08). He pointed out some limitations in the data subset used in the Dutch study and questioned the methodology used to derive the new proposed limits from the data subset. The expert from the Netherlands replied to the ETRTO comments (GRB-67-18).
16. The experts from Germany and OICA pointed out that the Dutch study had been based on tyre labels which might be incorrect. The expert from the Russian Federation drew the attention of GRB to the need for a holistic approach to the tyre rolling noise in the system “tyre/road surface”. The Chair noted two different approaches for tyre selection by the Netherlands and ETRTO: the Dutch study focused on the most popular tyres of several brands covering about 90 per cent of the market, while ETRTO was concerned about a much wider selection of brands to ensure market choice.
17. GRB invited the Netherlands, ETRTO and other stakeholders to work together with the aim to undertake a holistic study of tyres on the market. Finally, GRB agreed to resume the discussion at the next session.
Working Party on Noise | Session 68 | 12-14
Sep 2018
11. The expert from the Netherlands recalled his earlier proposals on strengthening the tyre noise limits and reported on new developments in this field (GRB-68-27), including a proposal for the new European Regulation on General Safety. Finally, he sought consent of GRB for transforming GRB-66-03, which had proposed stricter noise limits, into a working document for the next session of GRB. The experts of Norway and CAETS generally supported the idea of reducing noise limits in UN Regulation No. 117. The expert of ETRTO recalled their comments presented at the previous session (GRB-67-08). The expert from EC pointed out that the proposal for the new European Regulation was still under discussion. For this reason, the Chair felt that it would be premature to submit an official document with the new tyres limits to the next session.

GRRF discussed the possible options as well as the necessity of the creation of an informal working group to work on this matter. GRRF supported in principle the establishment of an informal working group and invited the expert from Germany and other interested experts to prepare draft terms of reference for the group to be reviewed by GRRF in February 2018.
