Tread for solid rubber tire

Abstract

A solid rubber tire and tread for use on a metal wheel rim includes a circumferential solid rubber tire having width and an inner radius at which the solid rubber tire engages across an outer surface of the metal wheel rim. The tire has an exterior rolling surface for rolling contact with the ground and opposed side walls connecting between the inner radius and the outer surface on both sides of the tire. A tire tread is formed with a first plurality and a second plurality of tread channels. The first plurality of tread channels are formed into the tire uniformly spaced circumferentially around the tire and extending inward from one of the sidewalls less than the entire distance across the width. The tread channels extend in a radial outward direction from a minimum tread radius adjacent to the inner radius of the tire and to the exterior surface so that the tread channels continuously extend to the rolling surface as the solid rubber tire wears. The second plurality of tread channels are formed into the tire uniformly spaced circumferentially around the tire and extending inward from the other sidewall less than the entire distance across the width. Each of the tread channels extending in a radial outward direction from a minimum tread radius adjacent to the inner radius of the tire and extending to the exterior surface so that the tread channels continuously extend to the rolling surface as the solid rubber tire wears.
