Zusammenfassung: | PROBLEM TO BE SOLVED: To reduce the fluctuation of a tire axle force caused by a lateral channel component in a tire pattern by increasing the rigidity of an edge part of a lateral channel in a pneumatic tire. SOLUTION: In the pneumatic tire 10 constituted by forming a plurality of block rows B1, B2, B3, B4 and B5 by channels 12 in the peripheral direction extending in the peripheral direction of the tire and lateral channels 16 extending in the direction of tire width in a step face part T of a tread part 11, a lateral channel wall 16a face of the tread part 11 is reinforced by a rubber layer 20 containing short fibers, and a road surface reaction force generated in the vicinity of the lateral channel wall 16a face is increased to reduce the fluctuation of an axle force by a tire tread. |
