Abstract:
A wheel and solid rubber tire assembly comprising:a. a metal wheel having a predetermined diameter and a cylindrical rim around the periphery of said metal wheel, said rim having a predetermined narrow width;b. a soft layer of rubber secured to said narrow rim, having a hardness in a range of 25 to 40 Durometer (on the Shore A Scale), having a first diameter and a first width at said first diameter, said first width approximately equal to said predetermined narrow width of said rim, and further having said soft layer with said narrow width at a second diameter larger than said first diameter; andc. a wear layer of solid rubber having a width substantially greater than said narrow width of said rim and soft layer and a thickness of more than 44% of the thickness of the tire, said wear layer comprising rubber having a hardness greater than about 60 Durometer (on the Shore A Scale), said wear layer secured to said soft layer at said second diameter so that a disparity in width results between said soft layer and said wear layer, said wear layer having a maximum diameter greater than said second diameter of said soft layer of rubber.
