Crown of a tire for a heavy vehicle of construction plant type is desensitized to attacks. The tire includes a tread (2) having a degree of surface siping TL, expressed in m/m2, equal to the ratio between the cumulative length LD of the cuts (21) and the area A of the radially outer surface (23) of the tread (2), and a protective reinforcement (4) having at least two protective layers (41, 42) that are formed of elastic metallic reinforcers and have a maximum breaking strength Rmax, expressed in daN/m, such that the degree of surface siping TL of the tread (2) is at least equal to 3 m/m2 and a coupling ratio C, equal to the ratio between the maximum breaking strength Rmax and the degree of surface siping TL, is at least equal to 30000 daN.
