The detailed understanding of the complex interaction between tire and road is of key importance in the tire development process. First, it is evident that the tire plays a role in state-of-the-art tire-vehicle systems like ABS, ESP etc. under continuously changing operating conditions like climate, road condition or tire condition. But in addition, tire development is confronted with the tremendous complexity of processes at the tire-road interface, being intrinsically connected to the contact mechanics of a rolling tire or a sliding tread block on wet/dry rough roads. All these aspects together represent a significant R&D effort, e.g. in the area of contact physics, compound development, tire testing or tire modeling. In our contribution we put emphasis on the influence of surface variations on the contact between a tire or a rubber block and a (rough) surface. This question is important as tires are used on various road surfaces which may differ for instance in surface topography, material composition, manufacturing processes or surface state (dry/wet, clean/dirty, etc.). Furthermore, many lab tests are performed on sandpaper or corundum surfaces, which again comprise different surface properties. We discuss some key factors based on advanced test methods and contact physics models.
