The pneumatic tire includes a belt layer having a circumferential reinforcing layer. Additionally, the pneumatic tire includes a plurality of circumferential main grooves, and a plurality of land portions partitioned by the circumferential main grooves in a tread portion. The width W1 of the land portion on a tire equatorial plane, and the width W2 of the second land portion at an end portion of the circumferential reinforcing layer have a relationship such that 1.05≦W1/W2≦1.30.
