Samenvatting
A detailed investigation has been made of the skidding resistance of smooth and patterned tyres with different treads of 7 polymers. It appears that hysteresis alone does not account for the high skidding resistance measured on some surfaces at high speeds but that the sequence of events arising from hysteresis losses on rough surfaces creates tyre/road contact conditions corresponding to lower speeds so that adhesion becomes directly and hysteresis indirectly responsible for the increased skidding resistance.
