Pneumatic Tire

In a tread portion of a pneumatic tire, an average lateral groove width Lc of a center region is obtained by dividing the groove area of lateral grooves in the center region by a circumferential length of the center region, and an average lateral groove width Lsh of a shoulder region is obtained by dividing the groove area of lateral grooves in the shoulder region by a circumferential length of the shoulder region. A relationship between a tire average thickness Gc of the center region and a tire average thickness Gsh in the shoulder region satisfies 1.05≤(Gc/Gsh)≤1.35, a relationship between the average lateral groove width Lc of the center region and the tire average thickness Gc in the center region satisfies 0.07≤(Lc/Gc)≤0.12, and a relationship between the average lateral groove width Lsh of the shoulder region and the tire average thickness Gsh in the shoulder region satisfies 0.17≤(Lsh/Gsh)≤0.26.
