The scope of the present paper is to summarize the governing equa- tions for rolling contact problems and to analyse a 3D tyre problem where the correlation between highway abrasion and factional energy is illustrated. 1 Introduction In tyre industry, all tyres have to pass a lot of different tyre tests before they can be put on the market. One of the most expensive tests is the highway abrasion test, in which specified tyres have to run about 20.000 to 40.000 km. The goal of our Finite Element simulation is to reduce the high test costs by a numerical simulation, and to get a b
