Abstract: A solid rubber tire for vehicle wheels is provided having a tenacious-hard tire base or bottom and also having the solid tire held between the rim flanges of the hub or wheel body. In order to be able to balance or equalize width tolerances of the tire foot or base and/or of the rim, the width of the tire foot or base is variable by one or more zones of reduced hardness, which preferably is attained by two or more zones of approximately equal cross sectional configuration or structure with reduced hardness, which zones are arranged distributed uniformly over the tire base or foot.

Abstract: A wheel and tire assembly for a vehicle, including a solid rubber tire, and a wheel body, one or both edges of which are provided with a circumferential groove for receiving a retaining ring for the solid tire. In order to be able to repeatedly mount the solid tire with a sufficiently reliable seating, there is inventively proposed to provided the solid tire with a base having a width such that when the retaining ring is omitted, the tire extends slightly into the region which would otherwise be occupied by the retaining ring. Accordingly, when the retaining ring is inserted, the base of the tire must be slightly elastically deformed, thus assuring a secure seating of the tire on a wheel rim therewith.
