摘要： Passenger vehicle tire having a tread extended on either side by sidewalls, this tread being provided with an asymmetric tread pattern with respect to a median plane that divides this tread into two parts with the same axial width, this axial width being measured in a direction parallel to the axis of rotation, an external part and an internal part, this external part being situated between this median plane and the sidewall intended to be positioned on the outside of a vehicle, and the internal part being situated between the same plane and the sidewall intended to be positioned towards the inside of the same vehicle, the internal part and the external part each having at least one void that forms a groove or is intended to form a groove when the tread has partially worn away, these voids defining, in the new state and for each (internal and external) part, a total voids volume Vi0 and Ve0, respectively, and a voids surface ratio Ti0 and Te0, respectively, these ratios being other than zero and such that, in the new state, there is a ratio R0 between the voids volume of the internal part and the voids volume of the external part, and for each degree of wear (U) chosen between the initial state and the wear limit of the tread there is a ratio RU between the voids volume of the internal part and the voids volume of the external part, this tire being characterized in that the ratio RU is greater than the ratio R0 at least starting from a degree of wear of 80% measured over the thickness of the tread to be worn away.
摘要翻译：具有胎面在任一侧通过侧壁延伸的胎面胎面，该胎面相对于将该胎面分成具有相同轴向宽度的两个部分的中间平面设置有不对称胎面花纹，该轴向宽度在平行的方向上被测量旋转轴线，外部部分和内部部分，该外部部分位于该中间平面和旨在定位在车辆外侧的侧壁之间，并且内部部分位于同一平面和侧壁之间旨在朝向相同车辆的内部定位，内部部件和外部部件各自具有形成凹槽的至少一个空隙或者当胎面部分磨损时形成凹槽，这些空隙限定在新状态和每个（内部和外部）部分，分别为总空隙体积Vi0和Ve0以及空隙表面比率Ti0和Te0，这些比率分别为 n为零，并且使得在新状态下，内部部分的空隙体积与外部部分的空隙体积之间存在比率R0以及在初始状态和磨损之间选择的每个磨损程度（U）胎面的极限存在内部部分的空隙体积和外部部分的空隙体积之间的比率RU，该轮胎的特征在于，比率RU大于至少从磨损程度开始的比率R0 在胎面的厚度上测量80％要磨损。
