发明名称 Pneumatic tire
摘要 A pneumatic tire comprises a tread portion (2) divided by three circumferentially continuously extending main grooves (10, 11) into two crown land portions (12) and two shoulder land portions (13). The axial width W2 of the shoulder land portion (13)is 1.15 to 2.0 times the axial width W1 of the crown land portion (12). Crown axial grooves (14) disposed in the crown land portions (12) have a groove width of at most 2 mm and are inclined to the opposite direction to the inclining direction of the radially outermost belt ply cords. shoulder axial grooves (20)disposed in the shoulder land portions (13) are inclined to the same direction as the inclining direction of the radially outermost belt ply cords. Each of the shoulder axial grooves (20) is not connected to the main groove (11) or alternatively connected to the main groove (11) through a narrow part (26) having a width of 1.2 mm or less.
