Tire

A tire comprising:

• a tread portion comprising a first tread edge, a second tread edge, a crown land portion arranged between the first tread edge and the second tread edge, and a first crown circumferential groove extending continuously in a tire circumferential direction adjacent to the crown land portion on a first tread edge side, wherein
• the first crown circumferential groove comprises a first groove wall on a crown land portion side, a second groove wall on the first tread edge side, and a groove bottom between the first and second groove walls, the groove bottom having a plurality of protrusions projecting in a tire radial direction,
• the crown land portion is not provided with drainage grooves that have an opening width exceeding 2.0 mm at a ground contact surface of the crown land portion and a depth exceeding 2.0 mm of an area where a distance between two opposite groove walls thereof exceeds 2.0 mm,
• the crown land portion is provided with only a plurality of sipes,
• each of the plurality of sipes has a main body portion with a width of 1.5 mm or less between two opposite inner walls,
• the plurality of protrusions comprises a plurality of first protrusions arranged in the tire circumferential direction, and a plurality of second protrusions arranged in the tire circumferential direction on the first tread edge side with respect to the plurality of first protrusions,
• in a tread plan view,
• each first protrusion comprises a first side surface extending in parallel with the tire circumferential direction on a groove centerline side of the first crown circumferential groove and a first surface extending from the first side surface in a tire axial direction toward the first groove wall,
• each second protrusion comprises a first side surface extending in parallel with the tire circumferential direction on the groove centerline side of the first crown circumferential groove and a first surface extending from the first side surface of the second protrusion in the tire axial direction toward the second groove wall, and
• the first side surface of each first protrusion and the first side surface of each second protrusion are on a same tire circumferential line,
• the plurality of sipes comprises a plurality of second crown sipes having opening ends connected to the first crown circumferential groove and closed ends in the ground contact surface of the crown land portion,
• the second crown sipes are provided with chamfer portions,
• the chamfer portions of the second crown sipes have a constant chamfer width in a longitudinal direction of the second crown sipes, and
• none of the closed ends of the plurality of second crown sipes is connected to any other groove or sipe.
