Abstract
An evaluation method for pneumatic tires and a system thereof, is provided, capable of appropriately evaluating an adverse effect, such as deterioration, of tire temperature by expressing severity of a temperature imposed on a member of tire made of rubber or the like in quantitative and convenient manners. Detection counts are calculated for each detected temperature according to a detection counts calculating unitbased on information of temperatures of pneumatic tires detected by a temperature sensor of a temperature detector. Temperature severity numbers of the pneumatic tires are calculated from a computing equation by a severity calculating unitbased on the detection counts and contribution coefficients of deterioration of tire rubber with temperatures stored in a contribution coefficient storageas parameters. Using the calculated temperature severity number, a determination unitdetermines thermal deterioration of the tire.
