Abstract
The new sealant layer is presented, which is easier to include into the manufacture process of the tire in comparison with the previous research. The performance of the present tire was investigated, and it was clarified that there was no air leak when nails broke it. Vibration characteristics of the present tire were analyzed theoretically and experimentally, and the effects of the sealant on the road-ability and the road noise were investigated. Using the analysis, it is shown that vibration transmissibility decreases in the present. The impact characteristics are also discussed. The transmissibility is also decrease when the impact load applies to the tire, and load noise is also decreased
