The paper presents an analysis of tangential interaction between flexural properties of tyres and frictional properties of the tyre-road interface. Using simple models to represent tyre structure and friction, the traction-slip characteristics are derived for various situations of practical interest: a standing tyre subjected to monotonic and oscillatory loading, a stationary rolling tyre and especially that of the transition from standing to steady rolling. To gain deeper insight into the requirements for modelling flexural and the complex friction properties, the study examines the influence of the normal pressure profile, tyre structural properties and friction in the contact region on the overall and detailed characteristics of tyre traction. The analysis presented serves as a basic framework for modelling the complex tyre-road interactions such as that encountered in the snap-start problem of road vehicles.
