RECENT ADVANCES IN TIRE FAILURE ANALYSIS: ON SHOULDER SEPARATION IN BIAS TRUCK TIRES

Regarding the failure of bias truck tires due to the shoulder separation, the factors contributing to the cause of this mode of failure are examined. First, the initiation and propagation of cracks are observed through the monitoring of tire temperature. After establishing the site of crack initiation and the locus of crack propagation, the effects of tire temperature and rubber strength on the failure process are examined. It is concluded that, in order to improve the tire's fatigue endurance against the failure by the shoulder separation, 1) the rubber with better strength should be selected, 2) anisotropy in the rubber properties should be minimized and 3) the temperature at the shoulder during rolling should be minimized by use of tire cords which generate less heat under cyclic stressing.
