Abstract
Specific methods are given for examination of soil response under the moving wheel - reducing the information to provide an appreciation of both the stress and strain performance of the soil. The determination of contact stresses from a knowledge of the stress distribution in soil leads to a direct method for computation and assessment of the nature and size of the contacting surface. With this approach, it becomes possible to examine tire carcass stiffness, inflation pressure and other contacting surface characteristics in relation to production of soil distortion and ultimate draw-bar pull.
