Patterns were engraved on the tread of smooth tires,and the influence of tread pattern design,such as the width and depth of the longitudinal groove of the pattern,the width of the pattern block and the chamfer of the longitudinal groove,on tire noise was studied.The test results of the tire drum noise showed that the longitudinal pattern design of the tire had a certain impact on the tire noise.By optimizing the design of the width of the longitudinal pattern block and the width of the pattern groove,the noise of the tire could be reduced.
