The risk of accident increases significantly when tire rolls on ice comparing to the dry surface. The vehicle tirebecomes the main component of force transmission to the road and necessity of investigating the tire behavior becomes of highimportance. This paper presents results of tire force transmission measurement with two different winter tires at the sameoperating conditions. Longitudinal and lateral force coefficient characteristics as the functions of slip ratio and slip angle arepresented and discussed. The results showed a different lateral and longitudinal performance because of different tread patternand rubber compound.
