Abstract:
A wheel for a relatively slow vehicle used in industrial applications and incorporating a solid tire formed of dense elastomer material such as cast polyurethane, having a relatively large radial depth, for example six inches, a relatively large width, for example twelve inches, and a deep slot extending circumferentially around the tire and dividing the tire into sections separated by the slot with the ratio of the depth of the slot to the lateral width of each section being in the range of 0. 65 to 1. 75. The tire is bonded to the wheel rim and includes sidewalls containing concave surfaces terminating in relatively thin lips bonded to the outer edges of the rim, keeping stress in the edge of the tire relatively low which helps reduce tire failures from beginning in the edges of the tire along the rim edges.
