| Abstract: |
| The noise level of passenger car tire was measured in a reverberation laboratory. The change of the noise level of passenger car tires with different structure，size and tread pattern was investigated at different inflation pressure，load and speed. The results showed that the noise level of different tires could be evaluated through the noise measurement in the reverberation laboratory；the pattern shape，the number and the order of pitches had great influence on the noise level of tire. |
