Tire

A tire comprising a tread portion having a designated mounting direction to a vehicle, wherein

• the tread portion includes an inner tread end located on an inner side of the vehicle when the tire is mounted on the vehicle, an outer tread end located on an outer side of the vehicle when the tire is mounted on the vehicle, and a tread width which is a distance in a tire axial direction from the inner tread end to the outer tread end,
• the tread portion includes three circumferential grooves extending continuously in a tire circumferential direction with a groove width of 3.0 mm or more, and four land portions demarcated by the three circumferential grooves,
• each of the four land portions includes a plurality of blocks demarcated by a plurality of lateral grooves which completely extend across the land portion in the tire axial direction with a groove width of 1.0 mm or more,
• the land portions include an outer crown land portion adjacent to an outer shoulder land portion including the outer tread end,
• a tire equator is located on a ground-contact surface of the outer crown land portion,
• the outer crown land portion has a largest width in the tire axial direction among the four land portions,
• the width of the outer crown land portion is 25% or more of the tread width,
• each of the plurality of blocks has a block edge which defines a contour of a ground-contact surface thereof, and is formed with a plurality of sipes having a width of less than 1.0 mm, and
• an outer crown block edge sum ΣA which is a sum of lengths of all the block edges included in the outer crown land portion is 35% to 50% of a pattern block edge sum ΣB which is a sum of lengths of all the block edges included in the four land portions.
