Abstract
To provide a method capable of easily analyzing frictional energy of a rolling tire, in-plane pressure Pxy(L) and vertical pressure Pz(L) at one point of a tread produced by rolling the tire are measured, static frictional force R(L) is calculated and the frictional energy is calculated by determining a portion corresponding to the static frictional force R(L) equal to or larger than a primary maximum value as a slipping region LR.
