In this article a tyre is investigated which moves in lateral direction, i.e. perpendicular to its regular rolling direction, through sand, which is one representative of a deformable soil. This kind of motion could be a result of skidding of a car where the vehicle slides laterally over the side verge. In order to investigate this motion in the first step the influence of the compliance of the tyre is studied; the result is that a flexible tyre behaves similar to a stiff one. Therefore, in the second step, the simulations and the experimental investigations of the tyre are restricted to a stiff, nearly rigid tyre. The deformable soil is simulated using the Discrete Element Method (DEM). In order to estimate and identify the parameters of the DEM model, a method incorporating simple experiments is described. In the 6th section DEM simulations and experimental results for a full tyre-soil-interaction are presented.
