Two distinct worn surface morphologies typically develop as a result of tire-road interaction. The first is smear wear, characterized by a thin, sticky film that forms on the tire surface. The second is an abrasive wear pattern. This study investigates how these surface morphologies form and evolve in response to various parameters, including temperature, applied load and counter surface geometry. The study will focus on identifying the factors that lead to the formation of specific surface morphologies and the resulting frictional response.

• Influence of countersurface sharpness, temperature and load on friction
• Image analysis on the development of worn surface morphologies
• Video evidence of wear pattern formation
• Link between surface morphology and frictional response
