| A tire designed to be mounted and pressurized on a vehicle wheel rim that has at least one circumferential seat for a bead belonging to the tire and an outward radial projection in the vicinity of the seat. A circumferential crown is provided with a tread for ensuring contact with the ground. At least one bead has a portion suitable for being mounted on the rim seat.

The protective element is capable of deforming elastically in the direction perpendicular to the tire wall. The protective element is produced using a foam of a rubber-based material with a rigidity greater than 10 MPa (and preferably greater than 25 MPa) and a void ratio of between 15% and 60% (and preferably of between 25% and 40%). | ||||||
