The invention relates to an assembly for a tyre comprising a first fabric, a second fabric and a load-bearing structure comprising filamentary load-bearing elements made of heat-shrinkable textile material connecting the first fabric to the second fabric, the load-bearing filamentary elements exhibit a thermal contraction CT, measured after 2 min at 185° C., greater than or equal to 5%.

A motorcycle tire comprises a carcass having a bias structure, a band comprising a jointiess ply, and a tread rubber disposed on the radially outside of the band. The loss tangent of the tread rubber at a temperature of 0 deg C. is larger in a tread crown region than in tread shoulder regions. The carcass comprises an outer carcass ply of carcass cords. The angles of the carcass cords with respect to the tire circumferential direction are smaller in the tread crown region than in the tread shoulder regions.

A tire includes a tread reinforcing layer. The tread reinforcing layer includes a ply reinforcing portion in which belt-shaped plies are wound. The ply reinforcing portion includes a lattice-shaped portion in which a plurality of the first inclined portions and a plurality of the second inclined portions intersect with each other such that side edges of the first inclined portions and side edges of the second inclined portions do not contact with each other so as to have space portions between them. Each of the first inclined portions and the second inclined portions has an angle with respect to a tire circumferential direction continuously decreased from an inner side in a tire axial direction to an outer side in the tire axial direction.

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.
