A vehicle tire includes tread blocks with a substantially-horizontal upper/top surface, a first pair of downward-sloping surfaces, a pair of horizontal shoulder surfaces, and a second pair of downward-sloping surfaces. The first pair of downward-sloping surfaces begins and slopes downward and outward from the upper/top surface. Each of the horizontal shoulder surfaces begins and extends outward from one of said first pair of downward-sloping surfaces. The second pair of downward-sloping surfaces begins and slopes downward and outward from the horizontal shoulder surfaces.

A pneumatic tire is provided with carcass layers and belt layers, which constitute tire components that extend in a tire circumferential direction, and at least one thread having a strength at break of 100 N or less that extends in the tire circumferential direction and is disposed at a step portion formed at width-directional end portions of the carcass layers and the belt layers.

A tire 2 includes a tread 4, a belt 16, and a band 18. The belt 16 includes belt cords 44. The band 18 includes band cords 60. The band 18 is composed of a band strip 58. The band strip 58 is a cord array in which the band cords 60 are arranged. A zone from a first end to a second end of the belt 16 is a control zone. Residual tension of the band cords 60 in the control zone is not less than 15.0 N. The control zone includes a crown zone and a pair of shoulder zones. Residual tension of the band cords 60 in the crown zone is higher than residual tension of the band cords 60 in each shoulder zone. A shape index of a reference ground-contact surface of the tire 2 is not less than 1.00 and not greater than 1.30.

The present invention relates to a cap ply reinforcement hybrid yarn (1) which is located between the tread and the belt package especially in radial passenger vehicle tires, which improves the high speed durability of the tire by using polyamide (N)/polyester (P) yarns, and which provides fuel saving by decreasing the rolling resistance.

A band 12 includes a center portion C, a pair of intermediate portions M, and a pair of outer end portions E. The center portion C is formed from a first band member 40 and that extends in a circumferential direction. Each intermediate portion M is formed from a second band member 42 and that extends so as to form a mesh-like shape. The second band member 42 includes a plurality of first tilt portions 44 extending so as to be tilted relative to the circumferential direction and a plurality of second tilt portions 46 extending so as to be tilted relative to the circumferential direction in a direction opposite to a direction in which the first tilt portions 44 are tilted. Each outer end portion E is formed from a third band member 54 and that extends in the circumferential direction.

A hybrid cord for a tire, a method of manufacturing the same, and a high-performance environment-friendly radial tire including the same are disclosed herein. The hybrid cord includes a high-modulus fiber ply and a low-modulus fiber ply. The hybrid cord has a stress-strain curve including an initial modulus section, an intermediate modulus section and a final modulus section. The initial modulus of the initial modulus section is higher than the intermediate modulus of the intermediate modulus section, and the final modulus of the final modulus section is higher than the intermediate modulus.

A tire 1 includes one or more conductive cords 2 embedded in the tire, and a communication device 10 embedded in the tire, in which a number of intersection points of the communication device and the one or more conductive cords is less than two on a projection plane in a tire width direction.

A method for retreading a wheel tire casing: a wheel tire casing is induction heated so as to soften a thermally malleable layer located between a tread of the casing and a carcass of the casing, the tread is removed from the carcass, and another tread is applied to the carcass.

Hooping layer (71) of a passenger vehicle tire has a force at break FR per mm of axial width of the hooping layer at least equal to 35 daN/mm, an elongation at break AR at least equal to 5%, and a secant extension modulus MA at least equal to 250 daN/mm, for an applied force F equal to 15% of FR. Working reinforcement (6) comprises single working layer (61) the working reinforcers of which form, with circumferential direction (YY), an angle A.sub.T at least equal to 30 and at most equal to 50. The carcass reinforcers of at least one carcass layer (81) form, with circumferential direction (YY) and in equatorial plane (XZ), angle A.sub.C2 at least equal to 55 and at most equal to 80 and having an orientation opposite to angle A.sub.T of the working reinforcers so that the carcass reinforcers and the working reinforcers constitute a triangulation.

A tire for a heavy construction-type vehicle includes a tread, a radial carcass reinforcement, and a crown reinforcement. The crown reinforcement includes a working reinforcement and a hoop reinforcement. The working reinforcement includes two working layers, each of which includes inelastic metallic reinforcers that are crossed from one layer to a next layer and that make an angle in a range of from 15 to 40 with respect to a circumferential direction. The hoop reinforcement, which is a ply that is wound circumferentially to form a radial stack of at least two hooping layers, includes circumferential elastic metallic reinforcers that make an angle equal to at most 2.5 with respect to the circumferential direction. The hoop reinforcement is radially positioned between the working layers, and the circumferential metallic reinforcers of the hoop reinforcement have a force at break equal to at least 800 daN.
