Measurement with tyre running at very low load skimload or deceleration method This second measurement is done to measure parasitic losses like bearing friction or aerodynamic losses that are included in the first measurement. Auth with social network: The pre-determined ISO alignment tyres cover a defined range of RRC and RR force, their load index covers a representative range and their dimensions are chosen that they fit on most test machines. Pneumatic tyres as we 2850 them today need the rubber materials and deformation to generate the required grip between vehicle and road surface, to give vehicle comfort uso generate low rolling noise.
