Abstract:
      Under the same driving condition and mileage，the wear degrees of tire from five brands were studied，wet braking performance，dry braking performance and interior noise tests were conducted on both new and worn tires from different brands to explore the effect of tire wear on vehicle performance.The results showed that the wet braking distance of worn tire was greater than that of new tire，the dry braking distance was less than that of new tire.The interior noise of worn tire was greater than that of new tire，and with the vehicle speed increased，the noise growth rate of worn tire was greater than that of new tire，indicating that tire wear led to increase interior noise.
