It has been found that tread rubbers differing little in mechanical strength and fatigue resistance determinated with Goodrich and de Mattia apparatus can show remarkable differences in the rate of mechanical relaxation processes. On the basis of relaxation time measurements it has been shown that tested tread rubbers can be described by at least four processes of stress relaxation. An optimization of properties of rubber working under stress test requires taking into consideration the result of relaxation.
