Title:
空気入りタイヤ
Document Type and Number:
Japanese Patent JP7399679
Kind Code:
B2
Abstract:
A pneumatic tire can suppress uneven wear of the tire and improve the performance on snow. A plurality of inner side circumferential grooves (11a, 11b, 11c) arrayed between a pair of outermost side circumferential grooves (11d, 11d) have a groove width that is smaller than that of the outermost side circumferential grooves (11d) to such a degree allowing land portions on the opposite sides thereof to come into contact with each other upon grounding. A plurality of recessed portions (S) of a shape cut in a radial direction from a tread face are formed along the tire circumferential direction on opposing block wall faces (14Af, 14Bf) of blocks (14A, 14B) on the opposite sides of at least one (11b) of the inner side circumferential grooves.
