This paper aims to give an overview on the most challenging tasks of today and tomorrow for tyre simulation success in complete vehicle environments. It gives some comments on the achieved level of maturity in tyre simulation, mentions weak spots and issues in daily woik, and suggests some areas worth working on, e.g. open standardised reference implementations of tyre simulation models to improve the cooperation in the vehicle dynamics community of researchers, tyre suppliers, and car manufacturers. It also gives insight into the efficient curved regular grid approach to represent digital road profiles for simulation purposes. To get better insight into the rubber friction dependency on slip speed and local pressure, we did some lab testing with rubber probes on a specially developed linear friction tester. Depending on the surface material, the rubber probe was sliding on, we got significant friction value dependencies on local pressure. With this information, we motivated the implementation of a new tyre model feature in one of our used tyre structure models to represent this dependency. We expect this will help to improve the capability to calibrate the tyre model closer to measurement reality and thus increase total simulation accuracy, but there is still work necessary to find a robust parametrisation procedure for this property in general.
