充气轮胎
摘要：
一种充气轮胎，其中，中间陆地部(6)被沿轮胎周向交替设置的第1中间横沟(10)与第2中间横沟(20)划分为多个中间花纹块。第1中间横沟(10)包括与胎冠主沟(3)连通的第1沟部(11)以及与胎肩主沟(4)连通且沟宽比第1沟部(11)小的第2沟部(12)，第2中间横沟(20)包括与胎肩主沟(4)连通的第3沟部(23)以及与胎冠主沟(3)连通且沟宽比第3沟部(23)小的第4沟部(24)。中间陆地部(6)具有：第1中间槽(30)，其在第2沟部(12)的附近，从胎肩主沟(4)朝向胎冠主沟(3)延伸，并在中间陆地部(6)内终止；以及第2中间槽(40)，其在第4沟部(24)的附近，从胎冠主沟(3)朝向胎肩主沟(4)延伸，并在中间陆地部(6)内终止。
摘要（英）：

A middle land portion is divided into multiple middle blocks by first middle transverse grooves and second middle transverse grooves arranged alternately in the tire circumference di recti on. The fi rst middle transverse grooves include a fi rst groove portion which communicates with a crown main groove, and a second groove portion which communicates with a shoulder main groove and is less wide than the first groove portion; the second middle transverse grooves include a thi rd groove portion) which communicates with the shoulder main groove, and a fourth groove portion which communicates with a crown main groove and is less wide than the third groove portion. The middle land portion has first middle slots which are disposed near a second groove portion, extend from the shoulder main groove towards the crown main groove and end within the middle land portion, and second middle slots which are disposed near fourth groove portions, extend from the crown main groove towards the shoulder main groove and end within the middle land portion.
