摘要： A pneumatic tire includes a tread portion provided with a pair of shoulder main grooves adjacent to each tread edge and a pair of center main grooves disposed axially inwardly of the shoulder main grooves to define a pair of middle portions each of which is between the adjacent shoulder main groove and center main groove. The center main grooves have groove widths larger than the groove widths of the shoulder main grooves. The respective middle portions are provided with a plurality of inner middle lug grooves extending axially outwardly of the tire from the center main groove, and a plurality of outer middle lug grooves extending axially inwardly of the tire from the shoulder main groove. The total number of inner middle lug grooves is smaller than the total number of outer middle lug grooves in each middle portion.
摘要翻译：充气轮胎包括：胎面部，其设置有与胎面主缘相邻的一对胎肩主槽;以及一对中心主槽，其设置在胎肩主槽的轴向内侧，以限定一对中间部，主槽和中心主槽。中心主槽具有比肩主槽的槽宽大的槽宽。各个中间部分设置有从中心主槽沿轮胎轴向向外延伸的多个内中间横向横向槽，以及从胎肩主槽沿轮胎轴向向内延伸的多个外侧中间横向花纹沟。内中间横沟的总数小于每个中间部分中的外侧中间横沟的总数。

摘要： A pneumatic tire includes a tread portion provided with a pair of center main grooves to define a center portion therebetween, a pair of shoulder main grooves arranged axially outside the center main grooves to define a middle portion between the center and shoulder main grooves, and middle lateral grooves to divide the middle portion into middle blocks. Each center main groove extends in a zigzag manner including inclined long sides and inclined short sides alternately arranged in a circumferential direction of the tire. The center portion is provided with at least six center sipes within a circumferential region corresponding to a pitch of middle lateral grooves. Each middle block has a circumferential length of 85% to 95% the pitch, and is provided with at least one middle sipe. The number of middle sipe on each middle block is five or less.
摘要翻译：一种充气轮胎，具备：胎面部，该胎面部具有一对中心主槽，在其间形成中央部;一对胎肩主槽，位于所述中央主槽的轴向外侧，形成在所述中心部和胎肩主槽之间的中间部，横向槽将中间部分分成中间块。每个中心主槽以锯齿形的方式延伸，包括沿轮胎的圆周方向交替布置的倾斜的长边和倾斜的短边。中心部分在对应于中间横向槽的节距的圆周区域内设置有至少六个中心刀槽花纹。每个中间块具有85％至95％间距的圆周长度，并且设置有至少一个中间刀槽花纹。每个中间块的中间刀槽花纹的数量为五个或更少。

摘要： A pneumatic tire is provided in a tread portion with a center land portion which is defined between center main grooves and whose top surface has a certain area and a maximum axial width of 15% to 19% of a tread width. The center land portion is provided with axial sipes and recesses. The recess extends from the center main groove toward the tire equator, and has a depth of 60% to 80% of the depth of the center main groove. The total area of the recesses is 5% to 9% of the area of the above-mentioned top surface. The center land portion is formed as a substantially continuous rib.

摘要： A pneumatic tire has a tread portion provided with two crown main groove and two shoulder main grooves and divided into a center land zone, two middle land zones and two shoulder land zones. The middle land zone is provided with middle auxiliary grooves. The shoulder land zone is provided with shoulder axial grooves. The width of the shoulder axial groove at the axially outer end is more than the width of the shoulder axial groove at the axially inner end. Through the shoulder main groove, the shoulder axial grooves are continued to the respective middle auxiliary grooves.
