The results demonstrate that the shape of the filler particles can have great influence
on the mechanical properties of the rubber composites and indicate a pathway to
design tires with desired properties. Let us also consider that the excess of mobility
of the filler particle also constitutes a loss of energy during the rolling of tire and
this opposes the principles of a green material.
