Many automotive performance tests are conducted on chassis dynamometer, while tyrerollingresistance is an important factor to affect measuring accuracy.
许多汽车性能试验均在底盘测功机上进行，而轮胎滚动阻力是影响测试精度的重要原因。

Tyre designers have therefore sought to improve fuel economy by reducing rollingresistance.
轮胎设计者因此力求减少滚动阻力以提高能源利用的经济性。
