Rapid development of advanced driver assistance systems tends not only to use full grip potential, provided by pneumatic tire, but also to use a tire as a sensor. First required step on this way is understanding the physical background of tire behavior. This research is an attempt to decompose the handling tire properties into particular physical effects, which determine them. With help of optical measurements there was analyzed carcass deformation behavior. Using in-tire acceleration sensors there was measured the shape of the contact patch in different conditions. These relations were considered in a physical simulation model. The result is enhanced understanding of the most important physical processes and effects of a rolling tire and their influence on its transient handling behavior.
