Abstract
A puncture resistant pneumatic tire has a tread portion and a pair of lateral tread edges. A belt package is located radially inward of the tread portion and a carcass structure has at least one body ply which extends between and is turned up around a pair of bead cores. A protective band extends circumferentially about the tire radially beneath the tread portion and includes a plurality of circumferentially spaced metal rods, each of which extends in a lateral direction between the tread edges. The protective band may be located radially inward or outward of a spiral ply layer and the rods may be arranged in a staggered laterally offset layered relationship. The rods have a circular cross-section with a diameter of between 1/16 inch and ¼ inch and a length of between 7 inches and 8 inches and will deflect and dislodge the pointed end of road debris before it completely punctures the tire.
