We investigate the possibility of substantial inflation of short-periodJupiter-mass planets, as a result of their internal tidal dissipationassociated with the synchronization and circularization of their orbits. Weemploy the simplest prescription based on an equilibrium model with a constantlag angle for all components of the tide. We show that for young Jupiter-massplanets, with a period less than 3 days, an initial radius about 2 Jupiterradii, and an orbital eccentricity greater than 0.2, the energy dissipatedduring the circularization of their orbits is sufficiently intense andprotracted to inflate their sizes up to their Roche radii
