摘要：Disclosed is a method for predicting tire performance in which a tire model,which comprises a tread pattern capable of imparting deformation by means of groundcontact and/or transfer, and a snow model, in which a snow-covered road surface thatcomes into contact with the tire model is represented, are used to predict tire

performance on the snow-covered road surface on the basis of physical quantities thatoccur in at least either of the tire model and the snow model. The snow model ismodeled as an elasto-plastic body or an elastic body, the nonlinearity of the volumecompression property of snow is represented by the relationship between the density orvolume strain of the snow and the pressure of the snow, and the shear property of thesnow is represented by the relationship between the yield stress of the snow and thepressure of the snow.
