Abstract : Field test of phase I results of the 11.00-20 integral tires indicated an improvement in performance over tires previously tested. However, with the increased mileage a sidewall cracking deficiency was noted. We believe that we have a method of correcting this problem as evidenced by the indoor sidewall cracking test results on the 16-20 size tires. All experimental tires tested prior to shipment passed endurance test requirements. With the information obtained from the test results on Phase I tires, construction features of the 16-20 low profile and 11.00-20 replaceable tread tires were revised. A contract modification change was made from synthetic tread and sidewall stock to a natural rubber compound with a neoprene veneer on the sidewall. This revised construction showed a vast improvement on indoor sidewall cracking test over results obtained with the previous construction. The initial 14 16-20 field evaluation tires were fluoroscoped and some irregular spacing of the cords in the breakers at the splice was found. The quality of these tires was questionable for penetration resistance and tread wear.
