More Information
Summary:The invention relates to a tyre (1) for civil engineering heavy vehicles, comprising a tread (2) having a height H radially outside at least one low hysteresis elastomer mixture layer (41) having a total filler content TG = TSi + TN, where TSi is the silica content and TN is the carbon black content. According to the invention, the tread (2) comprises, in the vicinity of at least one axial end (21), a plurality of crown cavities (6) and/or a plurality of side cavities (7) respectively distributed in the circumferential direction (XX '):-the crown cavities (6) have a depth PS, satisfying PS/H at least equal to AS + KS * RSi, where AS = 0.35, KS = 0.4 and RSi = TSi/TG,-the side cavities (7) have a depth PF, satisfying PF/H at least equal to AF + KF * RSi, where AF =-0.1, KF = 0.3 and RSi = TSi/TG. 本发明涉及一种用于土木工程重型车辆的轮胎(1)，其包括在至少一个低滞后性弹性体混合物层(41)径向外侧的具有高度H的胎面(2)，所述低滞后性弹性体混合物层(41)的填料总含量TG＝TSi+TN，其中TSi为二氧化硅含量，TN为炭黑含量。根据本发明，胎面(2)在至少一个轴向端部(21)的附近包括分别在周向方向(XX')上分布的多个胎冠腔体(6)和/或多个侧腔体(7)：-胎冠腔体(6)具有深度PS，满足PS/H至少等于AS+KS*RS
