In a side reinforcing type tire 2, when a cross-sectional height of the tire 2 is denoted by L, a height in a radial direction from a bead base line to an outer edge of a core 34 is denoted by HC, a point on a turned-up portion 42 of a carcass ply 38 at which point a height in the radial direction from the bead base line is 0.35 times of the height L is denoted by P1, and a point on the turned-up portion 42 at which point the height in the radial direction from the bead base line is equal to the height HC is denoted by P2, the turned-up portion 42 has, between the point P1 and the point P2, a shape that is a curved line projecting inward in an axial direction, a straight line, or a combination thereof.

A pneumatic tire has a carcass layer, a side wall rubber which forms an outer surface of a side wall portion, and a rim strip rubber which forms an outer surface of a bead portion. The rim strip rubber extends in a tire radial direction between the carcass layer and the side wall rubber. A height of the rim strip rubber on the basis of an outer diameter position of a bead core buries in the bead portion is equal to or more than 70% of a height of a tire outer diameter position. A thickness Tw of the rim strip rubber at the tire maximum width position is smaller than the maximum thickness Tm of the rim strip rubber which is closer to an outer side in the tire radial direction than the tire maximum width position.

A pneumatic tire includes one carcass including a folded up portion and a reinforcing layer between the folded up portion and a bead filler. The folded up portion has an end portion in a region inward of a belt layer in a radial direction and inward of the belt layer in a lateral direction. The bead filler has an outer end portion distanced from a bead heel portion from 20% or more to 40% or less of a tire cross-sectional height. The reinforcing layer has an outer end portion outward of the outer end portion of the bead filler in the radial direction and inward in the radial direction with respect to a position of a tire maximum width position in the radial direction. A sidewall portion is formed of a side rubber having tan at 60 C. of from 0.04 or more to 0.10 or less.

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.

A tire includes a pair of beads and a crown region including a circumferential tread disposed radially above a circumferential belt. The tire further includes a pair sidewalls extending from the pair of beads to the crown region. A body ply wraps around the pair of beads and terminates in a pair of turn up ends in the crown region, below the middle 30% of the circumferential belt. A conductive substance is disposed along a strip of the body ply.

A vehicle tire comprises first and second bead cores spaced apart from each other, a first casing layer wrapped around the bead cores, a second casing layer wrapped around the bead cores, and a tread layer. The first casing layer has first edge sections that overlap with each other at a zenith of the tire and terminate at first edges on opposing sides of the zenith. The second casing layer has second edge sections that do not overlap with each other and that terminate at second edges that are each substantially aligned with one of the first edges. The first and second casing layers are each made of a single unidirectional ply that are in different directions to each other. The sidewall regions and the zenith comprise four plies of casing layers throughout the tire. The tire can further include first and second sidewall reinforcements (e.g., rubber strips) positioned in the first and second sidewall regions.

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.

A two-wheeled vehicle pneumatic tire having a tread, a tire carcass, tire sidewalls, and two bead regions with a bead protective strip. The tire carcass is formed from a first carcass inlay and a second carcass inlay. The second carcass inlay is arranged radially inwardly of the first carcass inlay, and extends from a crown region (17) of the two-wheeled vehicle pneumatic tire and terminates at a second carcass inlay end under the bead protective strip. The two-wheeled vehicle pneumatic tire provides improved puncture protection whilst maintaining good rolling resistance. This is achieved in that the first carcass inlay is guided with a first carcass inlay turn-up over the particular tire sidewall as far as under the tread to a first carcass inlay end, and terminates there at the first carcass inlay end.

A bias tire includes two or more carcass layers, at least one belt disposed outward from the carcass layers in a tire radial direction, a reinforcing rubber layer disposed between carcass plies included in a carcass layer of the carcass layers. A belt width of a widest belt with the widest width of the belts is 110% or more and 150% or less of a tread developed width, and a position of an upper end portion of the reinforcing rubber layer located outward in the tire radial direction is apart 3 mm or more from an end portion of the widest belt.

A vehicle tire comprises a first casing layer spanning between and wrapping around first and second bead cores. The first casing layer has first edge sections that do not overlap with each other and stop short of a central tread region of the tire. A second casing layer has second edge sections that overlap the first edge sections of the first casing layer, and the second casing layer spans the central tread region. A tread layer spans the central tread region. A breaker belt is positioned in the central tread region between the second casing layer and the tread layer or between the first casing layer and the second casing layer. First and second sidewall regions are defined between the tread layer and the first and second bead cores, respectively. The sidewall regions comprise three plies of casing layers and the central tread region comprises two plies of casing layers.
