Abstract
A pneumatic tire includes inner land portions, formed between a center main groove and outer main grooves on both sides of the center main groove, which are divided into blocks by sub-grooves. A pair of the sub-grooves positioned on both sides of the center main groove is inclined in the same direction with respect to the tire width direction, disposed such that openings on the center main groove side overlap in the tire circumferential direction, and the circumferential components of the sub-grooves are continuous throughout the tire circumference. A groove width of the sub-grooves changes at a middle portion in the length direction such that the sub-grooves include a narrow width section positioned on the outer main groove side and have a groove width W1 that is relatively small, and a wide section positioned on the center main groove side and having a groove width W2 that is relatively large.
