A tire includes a carcass ply and a belt structure disposed radially outward of the carcass ply in a crown portion of the tire. The belt structure includes a first belt ply, a second belt ply radially adjacent the first belt ply, an overlay ply radially adjacent the first belt ply, a first wrap around strip encompassing both axial edges of the first belt ply, and a second wrap around strip encompassing both axial edges of the second belt ply. The overlay ply may have an axial width less than both a maximum axial width of the first belt ply and a maximum axial width of the second belt ply.

Tyre comprising a carcass, a belt package and a tread; said tyre comprising at least a reinforcement net made of a weaved textile material having a number of meshes ranging from 3 to 20, and wherein the threads are oriented between 25° and 65° relative to a longitudinal axis (X) of the tyre; said reinforcement net being arranged at least in the area of a centre of the tread and positioned inside the belt package or between the belt package and the tread; said weaved textile material having an elongation at break equal to or greater than 10%; said reinforcement net having a shorter transverse extension than the one of the belt package.

In the pneumatic tire, the ratio TW/SW of the ground contact width TW of the tire and the maximum width SW of the tire is 0.75 to 0.95. The tire width direction outside end of the belt layer extends in the tire circumferential direction and is positioned outside in the tire width direction than the circumferential direction groove formed most outside in the tire width direction. A width direction sipe extending in the tire width direction and closest to the tire circumferential direction end portion of the block and a width direction sipe adjacent to the width direction sipe and extending in the tire width direction are formed in the block, and a distance from the tire circumferential direction end portion to the width direction sipe along the tire circumferential direction is longer than a distance from the width direction sipe to the width direction sipe along the tire circumferential direction.

A tire for a vehicle includes a tire body having a circumferentially extending tread portion with an outer surface and an inner surface. First and second sidewalls are joined to the tread portion, and the first and second sidewalls terminate in first and second edges, respectively, and are configured to be secured within a flange of a rim of a wheel. In addition, the tire includes a tire insert comprising a circumferential hoop of resilient material and positioned adjacent to the inner surface of the tread portion. The tire insert may have an arcuate cross section and a width that extends across from the first sidewall to the second sidewall. The resilient material of the tire insert may comprise spring steel of a steel alloy and be in a state of compression.

A tread of a tire can include a cap layer and a base layer. A loss tangent of the cap layer at 30° C. may be not greater than 0.30, and a loss tangent of the base layer at 30° C. may be less than the loss tangent of the cap layer at 30° C. The base layer can be inward of a reference end of the tread in an axial direction A fixing layer can be between the cap layer and a carcass in a radial direction. A first end of the fixing layer can be outward of an end of the base layer in the axial direction, or a position of the first end of the fixing layer can coincide with a position of the end of the base layer in the axial direction. Adhesiveness of the fixing layer can be higher than adhesiveness of the cap layer.

The present invention relates to a tyre for bicycle wheels comprising a tread band containing an anti-puncture system capable of offering high resistance to the penetration of foreign bodies. In particular, the present invention relates to a tyre (100) for bicycle wheels comprising: —a carcass structure (2); and —a tread band (7) arranged in a radially outer position with respect to said carcass structure (2); characterised in that said tread band (7) is made by vulcanisation of a vulcanisable elastomeric compound comprising fibrillated polymeric fibres of micrometric dimensions, wherein at least one protective layer (6, 11) is interposed between said carcass structure (2) and said tread band (7), said protective layer (6, 11) comprising (i) a plurality of reinforcing cords of textile material oriented with respect to the equatorial plane of the tyre with an angle greater than 30°, (ii) a square fabric with textile fibres of the weft or warp oriented with respect to the equatorial plane of the tyre with an angle greater than 20°, or (iii) a non-woven fabric with randomly oriented textile fibres.

The present invention is directed to a tire comprising a tread, two sidewalls, a carcass and at least two belts arranged radially between the carcass and the tread in a crown area of the tire. The tread has at least one axially outer edge portion covering the axially outermost edge of at least one of the belts and comprising a different rubber composition than a portion of the tread neighboring the axially outer edge portion of the tread. Furthermore, one of the sidewalls at least partially covers and contacts the axially outer surface of the axially outer edge portion of the tread.

A pneumatic tire having a tread reinforcing component disposed between a tire inner cavity surface and a tire ground contacting surface, and made of a thermoplastic resin. On an arbitrary reference line which extends across the tread reinforcing component in parallel with the tire equator, a distance L1 in the tire radial direction from the tire inner cavity surface to the thickness center point of the tread reinforcing component is in a range of 50% to 95% of a distance L0 in the tire radial direction from the tire inner cavity surface to the tire ground contacting surface.
