Abstract: Tire includes a casing with an interior, and the casing has an inside diameter. A fill is provided in the interior of the casing. The fill includes a first layer and a second layer adjacent to the first layer. The first layer has an outside diameter and an inside diameter, and the outside diameter is the same as the inside diameter of the casing for contacting the casing. The first layer has a face and open voids. The open voids of the first layer have a first volume and are open to the face. The second layer has an outside diameter that is the same as the inside diameter of the first layer. The second layer has a face and open voids, and the open voids of the second layer have a respective first volume and are open to the face.

Abstract: A run-flat tire system comprising a tire and an tire core disposed therein, the tire core being an annular body of an elastic closed-cell material, the radially outside and inside of the tire core each provided with a circumferentially extending groove, the radially inner groove extending radially outwardly beyond a bead core line being drawn between the centers of the bead cores. When the tire is mounted on a standard rim, the radially outer groove forms a radially outer space extending circumferentially of the tire and having a cross sectional area of from 1 to 6% of the total sectional area of the tire cavity, and the radially inner groove forms a radially inner space extending circumferentially of the tire having a cross sectional area Si of from 10 to 25% of the total sectional area S of the tire cavity.

Abstract: A solid tire which is high in load-bearing capacity, while maintaining as high a resilience as a conventional hollow tire, and capable of sufficiently absorbing shocks while the vehicle is traveling with no cargo. It has an annular rubber member fitted in a rim of a wheel, and a tire fitted on the annular rubber member around its outer periphery. The annular rubber member has a groove formed in the outer surface thereof so as to extend along a ridge circling the outer surface of the annular rubber member. The groove expands axially of the tire toward the rim. When a small, impulsive load is applied to the annular rubber member, its portions on both sides of the groove are resiliently bent to absorb the load. When a larger load is applied continuously for a long time, the entire annular rubber member is resiliently compressed to bear the load.

Abstract: A lightweight, filler core tire construction for automotive and other vehicles, having a flexible composite outer layer structure and an inner flexible honeycomb core with a radial relief and said honeycomb is bonded to said outer layer, eliminating thus fully or partially pressurized air from the tire and increasing the safety of driving, damage resistance, and minimizing servicing of the tire. The structures are preferably made of a polyurethane polymer and various fibers and do not require a split rim for mounting and dismounting said tire.
