摘要： Tire tread comprising a tread surface intended to come into contact with a roadway, this tread comprising at least one sipe extending in a main direction D and of mean width E, this sipe comprising in the main direction D at least one part sipe of shallow depth HF and at least one part sipe of great depth HG, the depth HF being less than the depth HG, each part sipe of shallow depth and each part sipe of great depth comprising an end region, this tread further comprising at least one insert oriented in a direction different from the main direction D of the sipe, this insert being positioned wholly within the thickness of the tread so as to be situated radially on the inside of a part sipe of shallow depth HF, this tread being such that at least the part sipe of shallow depth HF situated radially on the outside of the insert is provided, at its end region, with a widening forming a channel of maximum width W, this maximum width W being greater than the mean width E of the sipe.

摘要： The tread has main grooves that delimit a central region of a width comprised between 15 and 25% of a total width W and that define the wearable thickness of the tread. The tread also has lateral regions on each side of the central region, and the lateral regions are divided into raised elements. The elongate elements are delimited by oblique secondary grooves which are inclined by a mean angle of between 35 degrees and 55 degrees with respect to the circumferential direction and have a depth P5 which is between 30% and 60% of the depth P. Each elongate raised element has an oblique cut which divides the element into two elongate element halves, and each oblique cut is formed by a sipe extended by an internal canal. The internal canal forms a new groove once the tread is partially worn before the oblique secondary grooves completely disappear.

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。

摘要： A tire having a radial carcass reinforcement, made up of a single layer of reinforcing elements anchored in each of the beads by being turned up around a bead wire, reinforced by a stiffener. The two working crown layers are the only ones present to form the crown reinforcement over at least 75% of the width of the tread, the absolute value of the difference between the absolute values of the angles α2 and α1 being greater than 7°, α2 being greater than α1 in terms of absolute value, the mean angle α satisfying the relationship 13+131*exp(−L/100)
