The present paper deals with a study of selected rubber compounds and their vulcanizates with partial substitution of used filler by adding selected alternative fillers.  Alternative fillers were mixed into rubber compounds as partial replacement of commonly used filler – carbon black. As alternative partial substitutes of fillers  we have chosen fine fractions e.g. of waste of thermoplasitcs. The difference of rubber compounds were in the amount of used alternative filler. We determined curing characteristics of prepared tread compounds and physical-mechanical and dynamic-mechanical properties of their vulcanizates. From the measured results it can be concluded that studied waste  can be used in the function of filler into rubber, as partial replacement of commonly used filler.
