发明名称 PNEUMATIC TIRE
摘要 PROBLEM TO BE SOLVED: To provide a pneumatic tire improving performance on snow while maintaining high rigidity of land parts when narrow grooves are formed on a tread surface. SOLUTION: The pneumatic tire 1 includes: a plurality of circumferential grooves 10-13 extending in the circumferential direction of the tire on a tread 5; land parts A-E formed between the circumferential grooves; and a plurality of narrow grooves 21-25 extending in the width direction of the tire on the land parts A-E. The angles θA-θE at which the narrow grooves 21-25 intersect with the circumferential direction are set to become smaller from the inner side toward the outer side in the width direction.
