The paper presents a way to compute analytically the radial force and the radial stiffness of a generic pneumatic tyre. The aspect ratio, the inner pressure, the diameter, the hoop tension and other geometrical parameters are given. The theoretical analytical formula is validated by means of a number of experiments. A good agreement is found which enables a deeper understanding of the relationship between tyre data and tyre load carrying ability. Additionally, the presented theory allows simple analytical tyre models to be included in the future into control algorithm of actual cars.

Abstract
The paper presents a way to compute analytically the radial force and the radial stiffness of a generic pneumatic tyre. The aspect ratio, the inner pressure, the diameter, the hoop tension and other geometrical parameters are given. The theoretical analytical formula is validated by means of a number of experiments. A good agreement is found which enables a deeper understanding of the relationship between tyre data and tyre load carrying ability. Additionally, the presented theory allows simple analytical tyre models to be included in the future into control algorithm of actual cars.File in questo prodotto:
