The purpose of the present invention is to provide a tire tread and a tire having said tread such that a higher level of on-ice/on-snow performance, especially on-snow performance, can be exhibited when the tread is still new while maintaining wet performance. This tire tread has: a plurality of ground-contact components which are divided by a plurality of grooves formed in a ground-contact surface which comes into contact with a road surface when the tire rotates, the upper surfaces of the plurality of ground-contact components constituting portions of the ground-contact surface; and a plurality of small recessed parts which open at the top and are recessed in the tire radial direction but do not communicate with each other. The depth h of the small recessed parts is 0.15mm-1.5mm when the tread is new, and the projected density of the small recessed parts (a value obtained by dividing the total sum of the projected lengths LP of the respective small recessed parts present on the upper surfaces of the ground-contact components, when projected on a plane which is parallel to the tire rotation axis and perpendicular to the upper surfaces, by the area (mm2) of the upper surfaces with no small recessed parts and then multiplying the result by 1,000) is 200 or higher.
