<p>This document specifies the method for measuring relative wet grip braking performance index to a reference under loaded conditions for new tyres for use on passenger cars on a wet-paved surface.</p>
<p>The methods developed are meant to reduce variability. The use of a reference tyre is necessary to limit the variability of the testing procedures.</p>
<p>This document applies to all passenger car tyres except for:</p>
<p>— special-use tyres marked with "ET";</p>
<p>— T-type temporary spare tyres;</p>
<p>— tyres fitted with additional devices to improve traction properties (e.g. studded tyres).</p>
