Tire comprising a crown surmounted by a tread, two sidewalls, two beads, each sidewall joining each bead to the crown, a carcass reinforcement anchored in each of the beads and extending into the sidewalls and into the crown, a belt extending into the crown circumferentially and located radially between the carcass reinforcement and the tread. At least one of its sidewalls is reinforced by a multiaxially stretched thermoplastic polymer film, positioned between and in contact with two layers of rubber composition, and on the outside with respect to the carcass reinforcement. Preferably, the thermoplastic polymer film has, irrespective of the tensile direction considered, a tensile modulus E which is greater than 500 MPa, a maximum tensile stress sigmamax which is greater than 80 MPa, and an elongation at break Ar greater than 40%.
