A vehicle tire comprises a first casing layer spanning between and wrapping around first and second bead cores. The first casing layer has first edge sections that do not overlap with each other and stop short of a central tread region of the tire. A second casing layer has second edge sections that overlap the first edge sections of the first casing layer, and the second casing layer spans the central tread region. A tread layer spans the central tread region. A breaker belt is positioned in the central tread region between the second casing layer and the tread layer or between the first casing layer and the second casing layer. First and second sidewall regions are defined between the tread layer and the first and second bead cores, respectively. The sidewall regions comprise three plies of casing layers and the central tread region comprises two plies of casing layers.

Provided is a rubber-cord composite, a tire reinforcing member including the composite, and a tire including the reinforcing member. The rubber-cord composite includes a reinforcing cord, and the composite forms a spiral cord layer in the tire reinforcing member. The twist coefficient of the reinforcing cord is 0.3 or less.

Crown reinforcement of an aircraft tire with improved mechanical strength in order to increase the burst pressure of the tire, during a standard pressure test. An aircraft tire comprises a working reinforcement made up of a strip (5) wound continuously in a zigzag, from a starting end (51) to an ending end (52), in a circumferential direction (XX) of the tire, along a periodic curve (7) forming a non-zero angle A with the circumferential direction (XX) of the tire and in an equatorial plane (XZ) of the tire. The starting end (51) and the ending end (52) of the strip (5) are positioned axially at a distance (DI, DF) at most equal to 0.25 times the axial width W.sub.T of the working reinforcement from an axial end (E1, E2) of the working reinforcement.

The reinforcing element (34) has a cross-section with a flattened overall shape having an aspect ratio greater than or equal to 5 and extending in a main direction (Z1). It comprises a lateral edge (46) made of a polymeric composition comprising a thermoplastic polymer, the lateral edge (46) extending in a general direction substantially parallel to the main direction. The reinforcing element (34) is such that R=(UcU1)/Uc>11%, where Uc is the average value of the microhardness of the reinforcing element (34) measured in its central part, and U1 is the average value of the microhardness of the reinforcing element (34) measured at its lateral edge (36). The lateral edge (46) does not have any ridges.

Provided is a tire that is lightweight and excellent in riding characteristics while suppressing an increase in cost.

A plurality of belt layers 7 are superimposed in a radial direction. The belt layers 7 include a plurality of steel cords 10 arranged in parallel in a row and rubber 11. The steel cords 10 have a 14 structure in which four filaments 20 are twisted, and when a center-to-center distance between the steel cords 10 in at least two of the belt layers 7 adjacent in the radial direction is T, and an average diameter of virtual circumscribed circles of the steel cords 10 having the 14 structure is D, 1.25T/D2.25.

An elastomeric article can include an elastomeric body that is at least partially formed from an elastomeric material. The elastomeric body can include a first surface portion and a second surface portion facing opposite the first surface portion. A first plurality of reinforcing elements can be embedded within the elastomeric body between the first and second surface portions. The first plurality of reinforcing elements can have a first end and a second end opposite the first end with the first plurality of reinforcing elements having a non-linear pattern formed therealong between the first and second ends thereof. As examples, the elastomeric article can at least partially form one of pneumatic or non-pneumatic tire, a flexible spring member of a gas spring assembly and/or a turnup bladder dimensioned for securement on an associated tire building machine. Methods of manufacturing an elastomeric articles are also included.

A run flat tire 1 comprises a carcass 6 formed of a carcass ply 6A extending between a pair of bead portions 4 in a toroidal manner and a side reinforcing rubber layer 9 having a substantially crescent cross-sectional shape disposed on an inner side of the carcass at each of sidewall portions. steel cords 60 each including 1 to 4 filaments 61 having a strand diameter in a range of from 0.25 to 0.30 mm are arranged in the carcass ply 6A, and an outer diameter D of each of the steel cords 60 is not less than 0.62 mm.

Pneumatic tire for heavy duty vehicles having a crown portion comprising two working plies (114,116) and a breaker ply (120) radially outward of the carcass body ply wherein the breaker ply (120) comprises a plurality of breaker ply reinforcement elements (122) having a length L of no more than 155 mm, at an angle of 5<60.

A motorcycle tire comprising: a carcass extending between a pair of bead portions 4 through a tread portion 2 and a pair of sidewall portions 3, and a band 7 disposed radially outside the carcass in the tread portion. The band 7 is composed of a ply of a spirally wound steel band cord 10, and the steel band cord 10 has a compressive stiffness of not more than 500 N/mm, a bending rigidity of not more than 15.0 g cm, and an elongation percentage at 49N of 0.5% to 2.5%.

The reinforcing structure for a tire is in the form of a stratified assembly formed of two layers of reinforcing strips of completely connected cross section, and flattened in shape. According to the method, the strips of each layer are laid side by side in a main direction of laying. The strips of the first layer are spaced apart by a distance that is less than the width of the strips of the second layer and in such a way that the edges of the strips of the first layer overlap the edges of the strips of the second layer. The two layers of strips are separated by a layer of uncoupling rubber.
