Method for estimating tyre cornering stiffness from basic tyre information

This paper proposes a simple mathematical tyre model that estimates tyre cornering stiffness. The model is derived by considering the tyre to be a combination of two independent systems. The sidewalls are assumed to be negligibly stiff in the lateral direction, and hence their influence on the lateral dynamics of the tyre will be ignored. The belt and tread area of the tyre will be considered to be an homogeneous uniform band, and its stiffness will be estimated with reference to measured tyre data. The resulting model is estimated to yield cornering stiffness values within about 30 per cent of the actual measured values
