The presented paper deals with the use of waste materials as ecological fillers into rubber matrix. Waste materials were used as partial replacement of the commercial filler – carbon black designated as N339. These prepared rubber compounds were characterized on the basis of the rheology and vulcanization characteristics (minimum torque M_L, maximum torque M_H, optimum time of vulcanization t_(c90), processing safety of compound t_s, rate coefficient of vulcanization R_v). In the case of the prepared vulcanizates, physical-mechanical properties (tensile strength, tensibility and hardness) and dynamical-mechanical properties (elastic modulus, viscous modulus, loss angle tg δ) were investigated. Using the dependency of loss angle on temperature, the selected properties for tyre tread vulcanizates were evaluated, including traction on snow and ice, traction on the wet surface and rolling resistance.
