TIRE

Mud performance is enhanced without degrading noise performance.A tire 1 has a plurality of blocks 5 formed by circumferential grooves 3 and lateral grooves 4. The plurality of blocks 5 include at least recess-equipped blocks 6 having recesses 10 disposed inward of a tread surface 5a in a tire radial direction and outward of groove bottoms 4s of the lateral grooves 4 in the tire radial direction. A ratio (Ar/At) of a total area Ar of the recesses 10 to a total area At of tread surfaces 5a of the plurality of blocks 5 is 10% to 20% in a ground contact surface 2a.
