    What is the S-identification

    According to the ECE-R 117 directive, the EU has defined certain thresholds for the noise levels of tyres.
    An "S" in connection with a digit sequence on the tyre wall shows that the tyre features reduced driving noise levels. Car tyres without such an "S" identification will not be allowed for sale after a staggered transition period.

    The transition periods for mandatory "S" identification are as follows:

    - From October 1, 2009 for car tyres (according to ECE-R 30) with a cross-sectional width of 185mm.
    - From October 1, 2010 for car tyres (according to ECE-R 30) with a cross-sectional width between 195 and 215mm.
    - From October 1, 2011 for car tyres (according to ECE-R 30) with a cross-sectional width over 215mm.
