German Road Safety Council - 2018
In the DVR Board resolution of 29th October 2013 requirements for increasing tyre safety were made, including an increase of the limit value for wet grip for the type test. On 17 May 2018, in its proposal for a regulation of the European Parliament and of the Council for the type-approval of motor vehicles, among other things the European Commission suggested further considerations with regard to tyre safety. Quote: "The process of adapting the requirements on tyres to take account of technical progress should continue at United Nations level, in particular to ensure that tyre performance is also assessed at the end of a tyre's life in its worn state and to promote the idea that tyres should meet the requirements throughout their life and not be replaced prematurely."1
The DVR supports the proposal of the European Commission for assessing the performance of tyres in their worn state as regards the complete range of minimum legal tread depth at the time of their approval. The DVR expects greater tyre safety, especially due to shorter braking distances in wet conditions for tyres which are in a used condition.
The DVR considers it to be a matter of urgency that the Board resolution of 2013 on the subject of "Tyres" is implemented, in which among other things, it is requested to change Regulation No. 661/2009 of the European Parliament and Council for the type approval of motor vehicles as well as Regulation No. 117.02 of the Economic Commission of the United Nations for Europe (UN/ECE), so that for summer tyres, the limit value for wet grip G is specified as ≥ 1.25. The current limit value for wet grip G is ≥ 1.10.
