Tire

A tire comprising a tread, wherein:

• the tread comprises:
• a plurality of circumferential grooves extending continuously in a tire circumferential direction;
• a plurality of lateral grooves connecting the circumferential grooves that are adjacent to each other in a tire axial direction;
• and
• a plurality of blocks divided by the circumferential grooves and the lateral grooves,
• wherein in one of the plurality of lateral grooves, a groove bottom is raised to form a tie bar connecting the blocks that are adjacent to each other in the tire circumferential direction,
• wherein the tie bar is the only tie bar in the one of the plurality of lateral grooves,
• the tie bar comprises two edges opposite to each other and a groove portion that penetrates the tie bar from one of the edges to another one of the edges in the tire axial direction, and
• in a state where the tire is assembled to a regular rim, filled with a regular internal pressure, loaded with a regular load, and brought into contact with a flat surface at a camber angle 0°, a side wall formed on the tie bar by the groove portion on one side in the tire circumferential direction is not in contact with a side wall on the other side in the tire circumferential direction,
• wherein each of the side walls is flat.
