A tire includes: a carcass ply, and an inner liner provided to a tire inner cavity side of the carcass ply, in which an electronic component is arranged between the carcass ply and the inner liner. Furthermore, the electronic component may be covered by rubber sheets.

When a tire that is mounted on a specified rim, inflated to an internal pressure of 50 kPa, and placed in a no-load state is viewed as a cross-section from the tire meridian direction, a position of 1.30Hf on an outer surface of a sidewall portion, taking a rim flange height (Hf) of the specified rim as a reference, is defined as a point (P), a foot of a normal line (L) drawn from the point (P) to a carcass line of a main body portion (131) of a carcass layer (13) is defined as a point (M), and a point of intersection of the normal line (L) and a carcass line of a folded back portion (132) of the carcass layer (13) is defined as a point (T). At this time, a distance (a) mm from the point (M) to the point (T), a distance (b) mm from the point (T) to the point (P), and a specified load (x) kN have relationships such that a=0.019x+13.3 and b=0.052x+21.6, with a tolerance of not less than 0% and not more than 20%.

In one aspect of a tire (10) of the present invention, a plurality of carcass plies (50a) include a first carcass ply (51). A first end portion (51a), which is a distal end portion of a portion of the first carcass ply folded around the bead core, is located outside in a tire radial direction from a position (WL) where a dimension in a tire width direction is maximum, and is located at a boundary portion (14) between a tread portion (11) and a sidewall portion (12), and in the portion located outside in the tire radial direction from the position where the dimension in the tire width direction is maximum, a dimension (T5) in a tire thickness direction between the portion of the first carcass ply folded around the bead core and an outer surface (12a) of the tire in the tire width direction is maximum between the first end portion and the outer surface of the tire in the tire width direction.

A method of making a tire includes providing a first body ply having a first width and laying a second body ply above the first body ply. The second body ply has a second width less than the first width. The method also includes laying a third body ply above the second body ply. The third body ply has a third width greater than the first width. The method further includes laying a first bead at a first location above the third body ply, laying a second bead at a second location above the third body ply, laying a first stabilizer ply insert at a third location above the third body ply, and laying a second stabilizer ply insert at a fourth location above the third body ply. The third location is between the first location and the second location, and the fourth location is between the third location and the second location.

In a tire, a tire outer diameter OD is in a range 200 mmOD660 mm. A total tire width SW is in a range 100 mmSW400 mm. A carcass layer is formed by layering two layers of carcass plies formed by covering organic fiber cords with coating rubbers. The organic fiber cords of the two layers of the carcass plies have cord angles in a range of 80 degrees or more and 100 degrees or less with respect to a tire circumferential direction. A tensile strength Tcs per a width of 50 mm of each of the two layers of the carcass plies (13A, 13B) is in a range 17 N/mmTcs/OD120 N/mm with respect to the tire outer diameter OD.

A tire can include a pair of beads, a carcass, a pair of protective rubber layers, and a pair of reinforcing rubber layers. A carcass ply of the carcass can include a ply body and a pair of turned-up portions. Each reinforcing rubber layer can be between the turned-up portion and the protective rubber layer. An outer end of an apex of each bead can be between an outer end and an inner end of the reinforcing rubber layer in a radial direction. A thickness of the protective rubber layer in a zone from a rim contact end to the outer end of the reinforcing rubber layer can be small at a center portion in the radial direction of the reinforcing rubber layer and can be large at another portion.

A pneumatic includes a pair of sidewall portions. At least one of the sidewall portions is provided on an outer surface thereof with a first protruding portion arranged on an outer side in a tire radial direction and a second protruding portion arranged on a radially inner side. Both protruding portions are formed so as to be convex outward in a tire axial direction. The second protruding portion has a protruding apex surface formed of a different colored rubber material having a different color from an outer surface of the first protruding portion. A distance in the tire radial direction between an inner edge in the tire radial direction of the first protruding portion and an outer edge in the tire radial direction of the second protruding portion is 40% or more and 220% or less of a length in the tire radial direction of the second protruding portion.

A pneumatic tire is provided. A bead filler is disposed on an outer circumferential side of each bead core in bead portions, a side reinforcing layer having a crescent-shaped cross-section is disposed on an inner side in a tire width direction of a carcass layer in a sidewall portion, and as physical properties of a rubber that constitutes the side reinforcing layer and a rubber that constitutes the bead filler, a modulus at 100% elongation is in a range from 8.4 MPa to 10.2 MPa, a tan at 60 C. is in a range from 0.04 to 0.08, and JIS hardness at 20 C. is in the range from 75 to 79.

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 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.
