A geometrical analysis is given of the tread motions occurring in the contact length of a rolling tire. Both the case of a free rolling wheel and that of a wheel under torque are discussed. We have derived expressions and curves for the relative slip and compressions which occur at the contact length for the two conditions. It is found that two important structural features control the nature of tread motions. These are the torsional rigidity of the sidewall and the compressibility of the tread. In addition, the implication of the analysis in tire design and performance are discussed.
