A single tyre or tyre set is tested first. If the measured values meet the declared classes or the declared external rolling noise value within the verification tolerances referred to in the table below, the tyre label shall be considered to comply with this Regulation.
If the measured values do not meet the declared classes or the declared external rolling noise value within the verification tolerances referred to in the table below, three additional tyres or tyre sets are to be tested; the average measurement value stemming from the three additional tyres or tyre sets tested is to be used to verify the declared information, taking into account the verification tolerances referred to in the table below.
Where the classes or values on the tyre label are derived from type‐approval test results obtained in accordance with Regulation (EC) No 661/2009, or UNECE Regulation No 117, Member States may use measurement data obtained from the conformity of production tests on tyres that were carried out under the type‐approval procedure established by Regulation (EU) 2018/858.
