A tire comprising at least:

• a tread in contact with a road surface;
• and
• a reinforcing belt disposed inside in a tire radial direction of the tread, wherein
• a circumferential groove extending along the tire circumferential direction is formed on the tread,
• the reinforcing belt has a reinforcing cord wound around a tire circumferential direction,
• the tensile elongation at break of the reinforcing cord is 10 cN/dtex or more,
• the reinforcing cord has an elongation at break of 13% or less,
• the reinforcing belt is formed by a cord unit in which a plurality of the reinforcing cords are arranged along the tire width direction and are wound around the tire circumferential direction, and
• the width of the cord unit in the tire width direction is narrower than the width of the circumferential groove in the tire width direction.
