Provided is a bias tire including: bead cores; a bead filler disposed outward of each of the bead cores in a radial direction; and a carcass layer stretching between the bead cores, wrapping around end portions of the bead cores, the carcass layer having opposite ends turned back to be fixed, wherein in a cross section in a meridian direction, a cord on an innermost side of the carcass layer in a tire lateral direction has a curved shape projecting laterally outward at a height from 0.9 times to 1.6 times a height of a flange of a rim on which the bias tire is assembled, and in the cross section in the meridian direction, a cord on an outermost side of the carcass layer in the lateral direction has a curved shape projecting laterally outward at a height from 1.1 times to 1.6 times the height of the flange.

A tire having no ply turnup is described. The tire includes a tread, a single layer of ply, a first triangular shaped bead and a second triangular shaped bead, wherein the radially inner end of the single layer of ply is secured between the first bead and the second bead.

A tire having no ply turnup is described. The tire includes a tread, a single layer of ply, and a first triangular shaped bead, wherein the radially inner end of the single layer of ply is secured between the first bead and a second bead, wherein the second bead is formed by spirally winding a strip of reinforcements onto the radially inner end of the ply, wherein the strip is formed of two or more parallel reinforcements.

A tire having no ply turnup is described, wherein the tire has a tread, a single layer of ply, a first column bead and a second column bead, wherein the radially inner end of the single layer of ply is secured between the first column bead and the second column bead.

A foldable tire includes a tire main body provided at two edges thereof with two tire beads respectively. A plurality of rings are disposed in each of the tire beads. Each of the rings has a reinforcing core, which includes a plurality of flexible steel filaments helically entwined with each other and has a diameter ranging from 0.2 millimeters to 0.5 millimeters, and a cladding layer clothing the reinforcing core, so that the reinforcing cores located in each of the tire beads are separated from each other.

Off road tires having a blended layer arranged in the crown portion are described for improving adhesion between the tread and underlying or adjacent tire components. Increased adhesion between tire components can reduce the frequency of separation and increase the service life of the tire. The blended layer contains a portion of the same material composition of a tire component that contacts the layer to ensure the blended layer has ingredients common with the adjacent component. As arranged between two tire components or layers, the blended layer can have a first portion and a second portion corresponding to compositions of the layers in contact with the blended layer. The incorporation of compositions in contact with the blended layer allows the blended layer to simulate entanglement between materials and increases the bonding strength between the layer and other components in the tire.

A pneumatic tire is provided that can achieve performance that is equivalent to or higher than that of known tires while allowing weight reduction of bead cores by using, for the bead cores, a composite cord. A pneumatic tire includes annular bead cores (5) embedded in bead portions (3), and a carcass layer (4) locked on the bead cores (5). Each of the bead cores (5) includes a cable bead structure in which a composite cord (10) is spirally wound around an annular core body (20), the composite cord including a core wire (11) formed of carbon fibers and a plurality of siding wires (12) formed of glass fibers disposed around the core wire (11).
