	Tyre lateral force is one of the most important parameters of the tyre and is critical for vehicle's handling and stability performance. For wheeled off-road vehicles, the effects of deformable surface on tyre performance must be considered. This paper presents a study on tyre lateral force measurement on three different deformable surfaces: loess soil, sandy soil and wet snow. The lateral force was measured on two front wheels of a light SUV by means of two 6-element Rotating Wheel Dynamometers (RWDs). The front wheels of the vehicle were turned by a steering robot installed in the vehicle to obtain repeatable excitation of the wheels at various angular speeds (100, 500 and 1500 deg/s) and frequencies (0.5, 1 and 2.5 Hz). During measurements, the test vehicle was pulled by a tractor vehicle of a significantly higher weight to ensure linear movement. This paper presents and discusses the tyre lateral force results and characteristics.
