Zusammenfassung:	A method for tire parameter derivation, tire cornering characteristic calculation and tire design is used with a tire dynamic model constituted by using a plurality of tire dynamic element parameters including stiffness and friction coefficient and parameter defining a distribution of contact pressure of the tire. The parameters and tire cornering characteristic are derived by using the combined sum of squared residuals being obtained by weighted addition of a first sum of squared residuals of lateral force and a second sum of squared residuals of self-aligning torque. The tire dynamic model is a model for calculating a lateral force and for calculating a self-aligning torque separately as a lateral force-based torque component generated by the lateral force applied on a contact patch of the tire and a longitudinal force-based torque component generated by a longitudinal force applied on the contact patch of the tire.
