Abstract: A pneumatic tire includes a tread, a pair of sidewalls extending from edges of the tread substantially in a radially inward direction, a pair of clinches extending from edges of the sidewalls substantially in the radially inward direction, a pair of beads positioned on axially inner sides of the clinches, and a carcass extending along an inner side of the tread and sidewalls such that the carcass is bridging the pair of beads. Each bead includes a fitting portion extending in a circumferential direction and formed to be fitted to a rim, the fitting portion has a bottom surface positioned on a radially inner side of the fitting portion and a side surface positioned on an axially outer side of the fitting portion, the bottom surface includes a heel on the axially outer side of the fitting portion, and the side surface includes a concave extending in the circumferential direction.

Abstract: A tire includes a tread having main grooves linearly continuously extending in tire circumferential direction, and a first land portion formed between the main grooves. The first land portion has first transverse grooves such that each first transverse groove is extending inclined in first direction with respect to tire axial direction and completely across the first land portion, and first blocks formed between the first transverse grooves such that one or more first blocks have a first slot extending from first side surface of the first block on one side in the tire axial direction, a second slot extending from second side surface of the first block on the opposite side in the tire axial direction, a first sipe extending from the first slot and terminating within the first block, and a second sipe extending from the second slot and terminating within the first block without intersecting the first sipe.

Abstract: A tire 12 includes: a tread surface 34; seat contact surfaces 58 each to be in contact with a seat S of a rim R; 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 F of the rim R, 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 F. The flange opposed surface 64 is formed to be a surface having a diameter increasing outward in an axial direction. A shape of the flange opposed surface 64 is represented by a circular arc, and a radius of the circular arc is not less than 11.0 mm and not greater than 20.0 mm.

Abstract: A tread portion has an outer tread end that is positioned on an outer side of a vehicle when mounted to the vehicle, a plurality of circumferential grooves that extend continuously in a tire circumferential direction, and a plurality of land portions that are defined by the circumferential grooves. The circumferential grooves include an outer circumferential groove that extends adjacently to a tire equator in a region closer to the outer tread end than the tire equator is. The land portions include an outer shoulder land portion that is defined between the outer circumferential groove and the outer tread end 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. The outer shoulder land portion has a first outer lateral groove that extends inward in the tire axial direction and terminates in the outer shoulder land portion. An angle of the first outer lateral groove relative to the tire axial direction at a terminating position in the outer shoulder land portion is 0 to 20°.
