Abstract

[Problem to be Solved] To improve wear life performance, anti-stone-biting performance and wet performance in a well-balanced manner. [Solution] Provided is a tire 1 in which a crown main groove 3 and a shoulder main groove 4 are provided. The crown main groove 3 is formed in a zigzag shape in which crown long side portions (3A) and crown short side portions (3B) are alternately formed in a tire circumferential direction. The shoulder main groove 4 is formed in a zigzag shape in which shoulder long side portions (4A) and shoulder short side portions (4B) are alternately formed in the tire circumferential direction. A crown long-short ratio (La/Lb), which is a ratio of a length (La) of each of the crown long side portions (3A) to a length (Lb) of each of the crown short side portions (3B), is larger than a shoulder long-short ratio (Lc/Ld), which is a ratio of a length (Lc) of each of the shoulder long side portions (4A) to a length (Ld) of each of the shoulder short side portions (4B).
