Improvement of High-speed/Durability Performance of Light Truck and Bus Tire
The principle and method of high-speed/durability test of tires were introduced,the common failure modes and stresses on different areas of light truck and bus tires were analyzed,and measures to improve the high-speed/durability performance of the tire were proposed.The failure modes of the tire in high-speed performance and durability performance tests were relatively similar,but the failure areas of the tire in the high-speed performance test were more reflected in the shoulder,while those in the durability performance test were more reflected in the bead.Reasonable profile and material distribution were beneficial for maintaining good high-speed/durability performance of light truck and bus tires.Thinning of the tread/sidewall and increasing the thickness of the ply coating could effectively improve the high-speed performance of the tire.Measures such as using 2-layer carcass cords for reverse wrapping,using low hardness apex,applying adhesive reinforcement film,and using carcass cords with thick adhesive coating were all conducive to improving the durability performance of the tire.
