Pneumatic tire for vehicle, has closed grooves that are formed in block units such that inclination angles of closed grooves with respect to tire width direction are selected among different angles

摘要

The tire has bead portions provided on inner sides of side wall portions which are provided on both sides of tread portion. The tread portion includes longitudinal grooves (1a-1e) extended in tire circumferential direction and side grooves (2a-2f) extended in lateral width direction. The rows of blocks (10-60) have block units (11-61) including three closed grooves (23a-23c) which have open end adjacent to longitudinal grooves. The inclination angles of closed grooves with respect to tire width direction are selected among different angles.
