摘要： A rubber tread covers an outside of a tire core having a diameter adapted for fitting on a rim of a wheel, and a peripheral groove is formed in the tire core along an outer peripheral top thereof to be expanded at its inner portion near the rim in an axial direction of a tire. A small load applied in a short time, such as a shock, is cushioned by an elastic bending deformation of that portion of the tire core, which surrounds the peripheral groove, and when a large load is to be born over a long term, the tire core undergoes bending deformation in the tread, accompanied by compressive deformation to provide cushioning. As a result, it is possible to exhibit a soft, elastic force as in a hollow tire without the sacrifice of a load resisting property of the solid tire to adequately cushion a shock from a road surface even when a vehicle in an unloaded condition runs.

摘要： A compound solid tire capable of preventing a core tire from being displaced from a cover tire and preventing the side part of the cover tire from opening, comprising the core tire formed of an annular elastic body and the annular cover tire having an inner peripheral surface fitted to the outer peripheral surface of the core tire, the cover tire further comprising a tread part and side parts, wherein the inner peripheral length of the cover tire at the inner peripheral surface center position is set to 92 to 99.5% of the outer peripheral length of the core tire at the outer peripheral surface center position.
