Tire Models: Mathematical Functions to Fit Measured Data Fiala: 6 parameters needed to describe a tire •Easy to understand the physical significance of all parameters •Simple force and moment equations. •Does not handle combined slip •Effects of normal force and camber are largely ignored. Pacejka 2002 : 117 parameters needed •Very good fit to experimental data •More complicated force and moment equations
