The influence of tread pattern design on noise was studied.The results showed that reducing the transverse groove width of the tread effectively decreased the order noise of the tire，with a particularly notable improvement in lower order pattern noise.When reducing order noise，the frequency corresponding to the maximum amplitude tended to shift forward.As the tire speed increased，the tread of pattern noise gradually intensified.However，the transverse groove width of the tread reduced，the pattern noise of the tire was smaller，and the difference between them did not change much at different speeds.
