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.
