The tire has a tread part (1) comprising four or more rubber layers each having a different complex elastic modulus at 30°C, wherein the tread part (10) has two or more circumferential grooves (11, 12, 13) extending continuously in a circumferential direction of the tire, a pair of shoulder land parts (16, 17) partitioned by the circumferential grooves (11, 12), and a center land part (18, 19) located between the pair of shoulder land parts (16, 17).
