In this paper the question of interaction of pneumatic extra-low pressure tires with snow is considered. The simulation model of contact interaction of pneumatic extra-low pressure tires with snow is presented. The model is realized by means of numerical computing environment MATLAB. Comparison of the settlement data with the data of experimental researches for the vehicle "Viking"-2992 on tires 1300х600-533 models "Trekol" is made. The analysis of parameters of wheel-terrain interaction of the off-road vehicles is carried out. The interaction parameters are received in mathematical dependence on air internal tires pressure in taking into account known physico-mechanical parameters of snow.
