The invention discloses a tire with a symmetrical tread pattern structure, which comprises a tread, four circumferential main grooves which are parallel to one another are formed in the tread at intervals, and the tread is divided into a central pattern rib, pattern ribs on two sides and tire shoulder pattern ribs by the circumferential main grooves; a plurality of S-shaped thin grooves are formed in the central pattern rib in the circumferential direction, a plurality of first inclined thin grooves and a plurality of second inclined thin grooves are formed in the pattern ribs on the two sides in the circumferential direction, the length of the first inclined thin grooves is larger than that of the second inclined thin grooves, the first inclined thin grooves and the second inclined thin grooves are distributed in a staggered mode, and the first inclined thin grooves and the second inclined thin grooves are distributed in a staggered mode. The inclination directions of the first inclined thin grooves and the second inclined thin grooves are opposite; a plurality of semi-closed inclined wide grooves are formed in the tire shoulder pattern ribs in the circumferential direction. According to the invention, excellent riding comfort and good dry and wet land controllability can be provided on expressways or common urban pavements, and meanwhile, low driving noise and rolling resistance are achieved.
本申请公开了一种对称胎面花纹结构轮胎,包括:胎面,胎面上间隔设置有四条相互平行的周向主沟槽,并通过周向主沟槽将胎面分隔为中心花纹肋条、两侧花纹肋条和胎肩花纹肋条;中心花纹肋条上沿周向设置有多个S型细沟槽,两侧花纹肋条上沿周向设置有多个第一斜向细沟槽和多个第二斜向细沟槽,第一斜向细沟槽的长度大于第二斜向细沟槽的长度,第一斜向细沟槽与第二斜向细沟槽交错分布,且第一斜向细沟槽与第二斜向细沟槽的倾斜方向相反;胎肩花纹肋条上沿周向设置有多个半封闭式斜宽沟槽。本发明能够在高速公路或普通城市路面上提供优异的乘车舒适性和良好的干、湿地操控性,同时具有较低的行驶噪声和滚动阻力。
