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.
