This report presents the first semi-empirical solution suggested to describe the traction versus slip relationship for rigid wheels. The kinematics of a slipping wheel are analyzed and the results are used to express the shear deformation as a function of slip which in turn is utilized in a new shear stress-strain relationship. The shear stresses are expressed at every point of the tire-soil interface surface and integrated to obtain the traction. Other established information is also briefly discussed, in order to complete the description of the state-of-the-art.
