It has been shown that in the case of cyclic mechanical loads on a porous elastomer there are regimes in which irreversible processes of heat transfer between the gas and the elastomer are responsible for the appearance of a nonzero heat flux averaged over the period and directed from the gas into the condensed phase; this heat flux is compensated for with the dissipation of mechanical energy from the loading source. A possible influence of this mechanism of dissipation on the heating of automobile tires is assessed. Possible methods of recording of this effect are discussed.
