摘要： [Problem to be solved]
To provide a tire that allows excellent steering stability and performance on snow and ice to be achieved.
[Solution]
A tire includes a tread part (2). The tread part (2) includes multiple main grooves that each linearly continuously extend in a tire circumferential direction, and a first land portion (11) that is formed by dividing the tread part (2) by the main grooves. The first land portion (11) includes multiple first transverse grooves (16), and multiple first blocks (20) that are formed by dividing the first land portion (11) by the first transverse grooves (16). At least one of the first blocks (20) is provided with a first slot (21) that extends from a first side surface (20a) on one side in a tire axial direction, a second slot (22) that extends from a second side surface (20b) on the other side in the tire axial direction, a first sipe (23) that extends from the first slot (21) and terminates within the first block (20), and a second sipe (24) that extends from the second slot (22) and terminates within the first block (20) without intersecting the first sipe (23).-

摘要： Provided is a tire that can allow achievement of both steering stability and ride comfort.
A tread portion 2 has an outer tread end Teo that is positioned on an outer side of a vehicle when mounted to the vehicle, a plurality of circumferential grooves 3 that extend continuously in a tire circumferential direction, and a plurality of land portions 4 that are defined by the circumferential grooves 3. The circumferential grooves 3 include an outer circumferential groove 3A that extends adjacently to a tire equator C in a region closer to the outer tread end Teo than the tire equator C is. The land portions 4 include an outer shoulder land portion 4A that is defined between the outer circumferential groove 3A and the outer tread end Teo so as to continuously extend therebetween in a tire axial direction, and that has the largest width in the tire axial direction among the land portions 4. The outer shoulder land portion 4A has a first outer lateral groove 5 that extends inward in the tire axial direction and terminates in the outer shoulder land portion 4A. An angle of the first outer lateral groove 5 relative to the tire axial direction at a terminating position in the outer shoulder land portion 4A is 0 to 20°.-

摘要： A tire (12) comprises a tread surface (34); seat contact surfaces (58) each to be in contact with a seat of a rim; and side surfaces (60) extending on and between the tread surface (34) and the seat contact surfaces (58); each side surface (60) includes a flange contact surface (62) to be in contact with a flange of a rim, and a flange opposed surface (64) which is located radially outward of the flange contact surface (62) and is to be opposed to the flange; the flange opposed surface (64) is formed to be a surface having a diameter increasing outward in an axial direction; the shape of the flange opposed surface (64) is represented by a circular arc, and the radius of the circular arc is between 11.0 mm and 20.0 mm
