Abstract
The pneumatic tire incorporates a reinforcement belt comprising two superposed median plies of metallic material and two laterally disposed marginal plies of nonmetallic material. The marginal plies are folded to form superposed flaps, with the corresponding flaps of each marginal ply being substantially aligned. In all embodiments of the invention at least one pair of corresponding opposite, laterally disposed flaps align with one of the median plies. In at least one embodiment of the invention the second pair of opposite, laterally disposed flaps align with the second median ply. In other embodiments of the invention the second pair of opposite, laterally disposed flaps overlap the terminal ends of the second median ply. And in still further embodiments of the invention the second pair of opposite, laterally disposed flaps are positioned radially outward or radially inward of the second median ply. In all embodiments of the invention there are at least two and at the most three layers of ply material at various points along the crosswise width of the reinforcing belt.
