Minimum tread depth Measure tread depth (S, fig. 78) at the point where tread is most worn down. It should not be less than 2 mm and anyway not below the legal limit. Important Visually inspect the tyres at regular intervals so as to detect cracks and cuts, especially on the side walls, and bulges or large spots that are indicative of internal damage. Replace them if badly damaged. Remove any stones or other foreign bodies caught in the tread. fig. 78 E 79
