Abstract: The present invention provides a tire with a synthetic fiber interior layer that adds flexibility and resistance to punctures from sharp objects. The present invention includes a rubber layer having an interior and exterior surface forming a substantially U-shaped tire cross section. Embedded between the interior and exterior surface of the rubber layer are radial plies extending across the tread, shoulders and sidewalls of the exterior surface. Sidewalls further include inner ends, wherein each radial ply folds back onto itself to form an enclosed bead chaffer region. An interior layer is coextensively and interiorly disposed along the radial ply. The interior layer is disposed within the tire cross section around the beads, and exits the tire cross section through the interior surface of the rubber layer and into the open interior of the tire. The interior layer is separable and freely positioned against the interior surface of the rubber layer.
