A tread for a pneumatic tire, the tread comprising a plurality of grooves, the grooves comprising: a groove surface (122); and a plurality of elements (410) spaced apart from each other in a configuration on the slot surface (122). Each element (410) has a shape defining a volume, the shape including: a first cross-sectional shape (425) in a plane (420) parallel to the slot surface (122); and a second cross-sectional shape (435) in a plane (430) perpendicular to the groove surface (122). The configuration includes a void volume in the space between the elements (410) and a void fraction between 0.5 and 0.75, wherein the void fraction is defined as a ratio of the void volume in the configuration relative to the total volume of the elements (410).
一种用于充气轮胎的胎面,胎面包括多个槽,槽包括:槽表面(122);和在槽表面(122)上的配置中彼此间隔开的多个元件(410)。各元件(410)均具有限定体积的形状,该形状包括:在平行于槽表面(122)的平面(420)中的第一截面形状(425);和在垂直于槽表面(122)的平面(430)中的第二截面形状(435)。配置包括在元件(410)之间的空间中的空隙体积以及在0.5至0.75之间的空隙率,其中空隙率被限定为配置中的空隙体积相对于元件(410)的总体积的比率。
