| Abstract: |
| Based on the European Union ECE R117 tire label regulation，the rolling noise determinaiton of C1 tire was studied.The results showed that the maximum and minimum rolling noise sound pressure levels differ by 7 dB（A） regardless of the type of pattern, speed rate，etc.There was no significant correlation between tire rolling noise，wet grip performance and rolling resistance.The tire noise could be reduced by structural optimization without affecting the wet grip performance and rolling resistance of the tire. |
