Separation Of Carcass And Rubber
Strong heating due to driving with substantially insufficient pressure led to overheating and subsequent separation of carcass from rubber material -arrows-. Refer to TIRE TEMPERATURE, RISING WHEN TIRES PRESSURE IS TOO LOW
The tire shown here was sporadically driven with tire pressure insufficient for the load. Typical indications for this are the circumferential abrasions in the area of the bead caused by the rim flange and the discoloration. Small, furrowed folds are visible along the inner sidewall.
When the tire rolls, strong shear forces develop between the steel belt layers, especially at the ends of the belts.
