In this pneumatic tire, a tread portion 12 is divided by four main grooves into a center land portion 22, an outer intermediate land portion 24, an inner intermediate land portion 26, an outer shoulder land portion 28, and an inner shoulder land portion 30. The center land portion 22 is formed with center lug grooves 32 in which the mounting outer side is narrower than the mounting inner side. The outer intermediate land portion 24 is wider than the inner intermediate land portion 26, and the outer shoulder land portion 28 is wider than the inner shoulder land portion 30. In the outer intermediate land portion 24, outer intermediate first lug grooves 42e and outer intermediate second lug grooves 44e are arranged in the tire circumferential direction so as to alternate with each other, the outer intermediate first lug grooves 42e communicating with the main grooves on both sides, and the outer intermediate second lug grooves 44e communicating only with the main groove 18 on the outside in the tire width direction. In the inner intermediate land portion 26, inner intermediate first lug grooves 42i and inner intermediate second lug grooves 44i are arranged in the tire circumferential direction so as to alternate with each other, the inner intermediate first lug grooves 42i communicating with the main grooves on both sides, and the inner intermediate second lug groove 44i communicating only with the main groove 20 on the inside in the tire width direction. |
