A motorcycle tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, a toroidal carcass extending between the pair of bead portions, and a belt layer and a band layer disposed outwardly in the tire radial direction of the carcass in the tread portion. The carcass includes a plurality of carcass cords. The band layer includes a jointless band ply having a band cord wound spirally at an angle equal to or less than 5 degrees with respect to a tire circumferential direction. The belt layer includes a plurality of belt cords arranged in a direction intersecting with the carcass cords. The belt cords intersect with the carcass cords at an intersection angle θc in a tread crown region, and intersect with the carcass cords at an intersection angle θs in tread shoulder regions, and the intersection angle θc is greater than the intersection angle θs.

A heavy-duty tire comprises a tread reinforcing belt comprising first to fourth belt plies each composed of belt cords inclined with respect to the tire equatorial plane. The first radial distance L1 between the belt cords of the third belt ply and the belt cords of the fourth belt ply is not more than the second radial distance L2 between the belt cords of the second belt ply and the belt cords of the third belt ply. The cord count E4 of the fourth belt ply is smaller than the cord count E3 of the third belt ply.

In order to improve shock burst resistance performance while suppressing a decrease in separation resistance performance, a pneumatic tire includes a tread portion, a belt layer, and a belt cover layer. The belt layer is disposed in the tread portion. The belt cover layer is disposed on an outer side in a tire radial direction of the belt layer. The belt cover layer includes: two layers of full covers disposed between shoulder regions on both sides in a tire width direction and layered in the tire radial direction; and a narrow cover formed with a width in the tire width direction narrower than widths of the full covers. The narrow cover is disposed at a position between the two layers of the full covers and on an inner side in the tire width direction than the shoulder regions.

A pneumatic tire having a carcass and a belt reinforcing structure, the belt reinforcing structure comprising: a zigzag belt reinforcing structure formed of a strip of reinforcement cords, the strip of reinforcement cords being inclined at 5 to 30 degrees relative to the centerplane of the tire extending in alternation to turnaround points at each lateral edge, wherein the strip of cords is formed from two different cords made of different materials.

A pneumatic tire comprises a carcass layer, a belt layer radially outward of the carcass layer, and a tread rubber radially outward of the belt layer. The belt layer includes an angle belt having a belt angle ≥45° and ≤70° in absolute values, a pair of cross belts having belt angles of ≥10° and ≤45° in absolute values and having belt angles of mutually opposite signs, and a reinforcing layer having a belt angle within ±5° relative to a circumferential direction. A width Ws of the reinforcing layer and a cross-sectional width Wca of the carcass layer satisfy 0.60≤Ws/Wca≤0.70. The cross belts are radially outward of the large angle belt. The reinforcing layer is radially outward of the pair of cross belts. A width Wb2 of a wider cross belt of the pair and Wca satisfy 0.79≤Wb2/Wca≤0.89.

A radial tire, notably for a passenger vehicle or van, has a very thin belt structure comprising a multilayer composite laminate of specific construction, with a first layer of rubber reinforced by circumferential textile reinforcers in the form of monofilaments or assemblies of monofilaments, preferably slightly heat-shrinkable, for example made of nylon or of polyester, this first layer radially (in the direction Z) surmounting two other layers of rubber, reinforced by high-strength steel monofilaments. The mean thickness of rubber, measured in the radial direction (Z), separating a first reinforcer from the second reinforcer which is closest to it, and that separating a second reinforcer from the third reinforcer which is closest to it, are both less than or at most equal to 0.35 mm.

A two-layer multi-strand cord (60) comprises an internal layer (CI) of the cord made up of J>1 internal strands (TI) and an external layer (CE) of the cord made up of L>1 external strands (TE). The cord satisfies the relationship 95≤MC≤175, where MC=(J×MI+L×ME)/(J+L); MI=200×cos.sup.4(α)×[Q×(D1/2).sup.2×cos.sup.4(β)+N×(D2/2).sup.2×cos.sup.4(γ)]/[Q×(D1/2).sup.2+N×(D2/2).sup.2]; and ME=200×cos.sup.4(α′)×[Q′×(D1′/2).sup.2×cos.sup.4(β′)+P′×(D2′/2).sup.2×cos.sup.4(δ′)+N′×(D3′/2).sup.2×cos.sup.4(β′)]/[Q′×(D1′/2).sup.2+P′×(D2/2).sup.2+N′×(D3′/2).sup.2], where D1, D1′, D2, D2′, and D3′ are in mm, α and α′ are the helix angle of each internal and external strand (TI), β and β′ are the helix angle of each internal thread (F1, F1′), δ′ is the helix angle of each intermediate thread (F2′) and γ and γ′ are the helix angle of each external thread (F2, F3′).

A tire with a tread reinforcing layer that includes a ply reinforcing structure formed by winding a cord-embedded rubber tape circumferentially of the tire. The ply reinforcing structure includes first oblique segments and second oblique segments which intersect with each other to form a mesh structure having rhombic spaces. The circumferential lengths of the rhombic spaces are less than ⅔ times the maximum circumferential length of the ground contacting patch of the tire in its normally loaded state.
