The cornering, braking, traction, rolling resistance and wear performance of tires depend on the generatedfriction forces. These friction forces depend not only on a specific compound, but also on theunderlying road surface. One of the challenges in numerical simulations is a correct prediction of thesefrictional forces. In commercial FEM packages, where usually only the Coulomb friction model ispresent, the surface roughness is not accounted for. It is well-known that for cornering under high slipangles the results with a Coulomb friction model are less accurate. By incorporating surface roughnessa more realistic friction model can be obtained, which should provide a better correlation between FEAand real road experiments.
