摘要
A method for determining preselected performance characteristics of a tire tread includes the steps of dividing the tread into a 3-D grid of cells; dividing a tread contact area into longitudinal and transversal strips; associating a longitudinal or transversal stiffness value with each strip using a linear relationship; assigning a preselected deformation state to each longitudinal and transversal strip; determining at least one single force, associated with each strip and acting in the longitudinal or transversal direction by means of the stiffness value and the deformation state; determining at least one total force associated with each contact area by summing all single forces, the total force representing at least one of the performance characteristics; determining a pattern of the total forces of all the contact areas; and analyzing the pattern of total forces to evaluate whether they assume values that optimize at least one preselected performance characteristic of the tread.
