Abstract: The present invention relates to a bias pneumatic tire having a belt structure comprising six annular layers. The tire of the present invention has particular utility as an aircraft tire and avoids many of the undesirable stresses/strains resulting from the deformation in the tread areas of the tire.

Abstract: A tire bead ring comprising round wires laid down in a parallelogram shape having an acute angle of 75.degree.-90.degree. is provided. The bead ring of the invention, when employed in a tire at a lay angle of 5.degree.-15.degree., provides a means for spreading out or dissipating twisting forces or torques encountered by the bead area of the tire to prevent separation of the bead from the rim during inflation and loss of air because of the flexing of the tire during running. Also, when the bead comprises multiple turns of a single round wire, a bead having reduced weight and good strength and uniformity may be provided.

Abstract: Tire bead members (10) have radially superposed layers (11,12,13,14) of fibers (15) embedded in a polymeric matrix (16). Interposed between the layers (11,12,13,14) of composite material are thin layers (17,18,19) of a material that is not adhered to both of the adjacent layers (11,12;12,13;13,14) of composite material. Tires employing said bead members are also disclosed.
