The tire comprises a carcass reinforcement which extends into sidewalls. The tire is also provided with a protection device that protects against external attack. The protection device comprises a plurality of raised elements of height H that are arranged in the circumferential direction. The tire is also constructed such that each raised element is formed of at least two parts which are at least partially disjointed from one another along a separation zone. The separation zone is oriented substantially in the circumferential direction. Each part is able to come into contact with another part of the same raised element when one of the parts comes into contact with an external obstacle.
