(28)Rolling resistance, wet grip, external rolling noise and other parameters should be measured in accordance with reliable, accurate and reproducible methods that take into account the generally recognised state‐of‐the‐art measurement and calculation methods. As far as possible, such methods should reflect average consumer behaviour and be robust in order to deter both intentional and unintentional circumvention. Tyre labels should reflect the comparative performance of the tyres in actual use, within the constraints arising from the need for reliable, accurate and reproducible laboratory testing, in order to enable end-users to compare different tyres and to limit testing costs for manufacturers.
