Radial tire/wheel assembly for high brake heat generated service

Abstract

A vehicle tire and wheel assembly for use in high brake heat generated service has an overall tire diameter (TD) of approximately 43 inches and an overall wheel diameter (WD) of approximately 24.5 inches to provide a ratio of approximately 1.76. The tire section height (H) is approximately 9.2 inches and the tire section width (W) is approximately 11.5 inches. The tire is of a radial construction containing steel reinforcing cords.
