To maintain its leadership in the tire business, MICHELIN is dedicating a great amount of resources to understand the physical and chemical mechanisms that drive the industrial performance and the quality of its products under various usage conditions. A tire is a composite that integrates a large variety of materials: textiles, metallic cables, elastomers, mineral fillers etc.). Mastering mixing of an elastomer with a higher-‐Tg oligomer is a promising route that is currently being explored in order to optimize the dynamical behavior of the final system in relationship with the traction versus rolling resistance compromise needed for tire applications. It is noteworthy that such material belongs to the more general kind of systems categorized as binary mixtures with dynamic asymmetry.
