(12)Regulation (EC) No 661/2009 also lays down minimum requirements for the wet grip of tyres. Technological developments make it possible to improve wet grip significantly beyond those minimum requirements, and thus to reduce wet braking distances. To improve road safety, it is therefore appropriate to update the provisions on the labelling of tyres to encourage end-users to purchase tyres with higher wet grip performance by providing them with harmonised information on the wet grip parameter.
