The first middle land portion 13 has plural first middle lateral grooves 41 at least one of which includes a shallow groove portion 16. The first middle land portion 13 includes an acute-angle-side corner portion 17 demarcated between the first crown circumferential groove 7 and the shallow groove portion 16. A chamfered portion 18 is formed at an end portion 17a, in the tire circumferential direction, of the acute-angle-side corner portion 17. The chamfered portion 18 includes an inclined surface 18a that extends from a ground contact surface of the first middle land portion 13 toward an end of the acute-angle-side corner portion 17, and is inclined relative to a tire radial direction.",
