A tyre for vehicle wheels comprises at least one structural component including a plurality of textile reinforcing cords (10), at least some of which comprise at least two yarns (20a, 20b) twisted together. At least one of said yarns (20a, 20b) is a texturized yarn (210) comprising a plurality of first filaments (201a) made of a recycled plastic material mixed with a plurality of second filaments (202a) made of a non-recycled plastic material.

The reinforcing element (45) comprises an assembly (49) made up: of a multifilament strand made of aromatic polyamide or aromatic copolyamide (46) and of a multifilament strand made of polyester (48). The two strands (46, 48) are wound in a helix around one another, and the reinforcing element (45) is twist-balanced. The twist factor K of the reinforcing element (45) ranges from 5.5 to 6.5 where K is defined by the formula: K=(RTi.sup.1/2)/957 in which R is the twist of the reinforcing element (45) expressed in twists per metre and Ti is the sum of the counts of the multifilament strands of the reinforcing element (45) in tex.

A crown reinforcement formed of at least two working crown layers of reinforcing elements. The tire additionally comprises, in each shoulder, at least one end of a layer of reinforcing elements that are mutually parallel in the layer and are oriented circumferentially, said end being axially outside said at least two working crown layers, the reinforcing elements of the carcass reinforcement having a diameter less than 0.85 mm, and said reinforcing elements of the carcass reinforcement being made up of threads with a diameter less than 0.16 mm.

A pneumatic tire is disclosed having two annular bead portions having a bead core. A carcass extends between the bead portions through sidewall portions and a tread portion, wherein the carcass includes at least two axially inner plies which extend down from the tread and axially inward of the bead core, said at least two axially inner plies being wound around the bead core forming respective turn-ups, each turnup being located axially outward of the bead core. The carcass further includes a first axially outer ply which extends down from the tread towards the bead core and positioned axially outward of the bead core, wherein at least one of the axially outer plies is formed from reinforcements having a higher break strength than the reinforcements of the axially inner plies.

Radial carcass tire for a civil engineering vehicle, having two bead wires (2) of radial height Ht, and carcass reinforcement made of two layers, the first (1) being radially innermost with a radial height Hdc, is anchored in each bead to form a main part (11) and a turn-up (12). The second layer (3) is radially outside the first layer (1). The free end (A) of the turn-up (12) is at a radial distance from the radially outermost point (21) of the bead wire that is at least equal to 1 and at most equal to 2 times Ht. From the end A of the turn-up (12) to the point B at 85% of the radial height Hdc, the distance between carcass layers is at least equal to 2 and at most equal to 11 times the diameter of metal reinforcers of first carcass layer (1).

Provided is a pneumatic tire including a belt layer. When the tread region indicates a region corresponding to a belt width of the belt layer and the side region indicates a region inward of a tire radial direction with respect to a tire maximum width position, the carcass cords forming the carcass layer are inclined with respect to the tire radial direction in the tread region, and at the same time, extend along the tire radial direction in the side region. The carcass cords forming the carcass layer and belt cords forming the belt layer cross with each other in the tread region.

A commercial vehicle tire of a radial type of construction with a cross-sectional height of 135 mm to 200 mm, a load index of 121 to 154, a radial-ply casing with at least one casing ply composed of steel cords embedded in rubber and with bead regions with bead cores and bead fillers around which the casing ply runs so as to form turn-ups.
