Abstract: A tire includes a first middle land portion having circumferentially extending first and second longitudinal edges. The first middle land portion is provided with middle lateral grooves. At least one of the middle lateral grooves includes a first groove portion extending in the tire axial direction from the first longitudinal edge, and a second groove portion extending in the tire axial direction from the second longitudinal edge. The first groove portion and the second groove portion are offset in the tire circumferential direction to form a pair of circumferential groove edges between a pair of groove edges of the first groove portion and a pair of groove edges of the second groove portion. A maximum groove depth of the first groove portion is different from a maximum groove depth of the second groove portion.

Abstract: A tire has a tread portion 2. The first middle land region 11 is provided with bend grooves 15 each having a first end 15a and a second end 15b. The first end 15a is connected to the first shoulder circumferential groove 5. The second end 15b is connected to one of the bend grooves 15 next in one of two opposite circumferential directions. Each bend groove 15 has two bent portions 16 and 17 at which the groove is bent. The bent angle ?1 at the first bent portion 16 is greater than the bent angle ?2 at the second bent portion 17.

Abstract: A tyre comprises a tread portion having a land region including a ground contacting surface defined between a first vertical edge and a second vertical edge and a lateral groove including a first portion extending from the first vertical edge, a second portion extending from the second vertical edge, and a connection portion connecting therebetween. The connection portion is a portion between a first small edge protruding circumferentially from the first portion and a second small edge protruding toward a circumferentially opposite side to the first small edge. A length in the tyre circumferential direction of each of the first and second small edges is smaller than a maximum groove width of each of the first and second portions. At least a part of the connection portion has a raised bottom portion having a depth smaller than that of the lateral groove at the first and second vertical edges.

Abstract: A tire comprises a center land region 25 provided with center sipes 7 having open ends 7E13 connected with a first center main groove 13 and a first middle land region 23 provided with middle sipes 8 having open ends 8E13 and 8E14 connected with the first center main groove 13 and/or a first shoulder main groove 14. The center sipes 7 include hook-shaped center sipes 55 crossing the center land region 25, and the middle sipes 8 include hook-shaped middle sipes 45 crossing the first middle land region 23.

Abstract: A tire includes a tread part having main grooves and lands demarcated by the main grooves. A crown land between a pair of crown main grooves includes first crown lug grooves extending from one crown groove to tire axial direction inner side and terminated within the crown land, second crown lug grooves extending from the other crown groove to the tire axial inner side and terminated within the crown land, and first crown sipes formed at tire circumferential direction positions and connecting the crown grooves, each first crown sipe includes a first side crown sipe piece extending from one crown groove to the tire axial inner side, a second side crown sipe piece not positioned on an extension line of the first side piece and extending from the other crown groove to the tire axial inner side, and a connecting crown sipe piece connecting the first and second sipe pieces.

Abstract: A tire includes a tread portion, and the tread portion includes a crown land portion disposed on a tire equator. The crown land portion includes: a first crown edge that extends in a tire circumferential direction on one side of the tire equator; a second crown edge that extends in the tire circumferential direction on the other side of the tire equator; a plurality of crown lateral grooves that extend from the first crown edge beyond the tire equator and terminate in the crown land portion; and crown sipes that include first sipe elements extending from the crown lateral grooves toward the second crown edge. The first sipe elements intersect the crown lateral grooves at an obtuse angle.

Abstract: A tyre comprises a tread portion having a land region including a ground contacting surface defined between a first vertical edge and a second vertical edge and a lateral groove including a first portion extending from the first vertical edge, a second portion extending from the second vertical edge, and a connection portion connecting therebetween. The connection portion is a portion between a first small edge protruding circumferentially from the first portion and a second small edge protruding toward a circumferentially opposite side to the first small edge. A length in the tyre circumferential direction of each of the first and second small edges is smaller than a maximum groove width of each of the first and second portions. At least a part of the connection portion has a raised bottom portion having a depth smaller than that of the lateral groove at the first and second vertical edges.

Abstract: A tire comprises a center land region 25 provided with center sipes 7 having open ends 7E13 connected with a first center main groove 13 and a first middle land region 23 provided with middle sipes 8 having open ends 8E13 and 8E14 connected with the first center main groove 13 and/or a first shoulder main groove 14. The center sipes 7 include hook-shaped center sipes 55 crossing the center land region 25, and the middle sipes 8 include hook-shaped middle sipes 45 crossing the first middle land region 23.
