The effect of the inflation pressure on the tyre properties and the motorcycle stability

Abstract

It is well known that the inflation pressure affects the tyre properties, which in turn influence the stability and safety of a vehicle. Single-track vehicles are characterized by some weakly damped vibration modes and are particularly sensitive to such variations. This work analyses the characteristics of a high-performance tyre set as a function of the inflation pressure through experimental characterization. The effect on the stability of a racing motorcycle is investigated at different speeds using an advanced motorcycle multi-body code.
