ABSTRACT
Road transportation on developed countries, both of passengers and goods, involves a huge figure of used pneumatic tires every year, what is a very important energetic and environ- mental problem. The retreading of a percentage of these used tires for be- ing re-used appears as a partial solu- tion, but still, retreaded tires have poorer mechanical properties than the new ones. This paper gives a gen- eral idea of actual retreading methods and presents a study carried out to characterize two important factors that can cause tire breaking, that is, static stiffness and temperature.
