A wheel and solid rubber tire assembly as provided with a metal wheel having a predetermined diameter and a cylindrical rim around the periphery of the wheel. The rim has a predetermined narrow width. A soft narrow layer of rubber is secured to the narrow rim and has a first diameter and a first width at the first diameter approximately equal to the narrow width of the rim. The soft layer has a second predetermined diameter larger than the first diameter. A wide wear layer of solid rubber, having a width that is significantly greater than the width of the narrow layer, is bonded to the narrow layer at the second diameter. The wear layer has a predetermined maximum outer diameter that is larger than the second diameter of the inner soft layer. The wear layer has a hardness greater than the hardness of the soft narrow layer. The movement of the soft inner layer upon compression is increased per pound of impact so that a smoother ride is provided. |
