Abstract: The tire for a construction plant vehicle includes a tread and a crown reinforcement arranged radially internal to the tread. The crown reinforcement includes a protective reinforcement, a working reinforcement, and a hoop reinforcement. The protective reinforcement includes at least one protective ply that exhibits a force at break FmNSP. The working reinforcement includes at least one working ply that exhibits a force at break FmNST. The hoop reinforcement includes at least one hooping ply, each of which includes hoop reinforcing elements that make an angle at most equal to 10° with a circumferential direction of the tire. The working reinforcement is arranged radially internal to the protective reinforcement. A ratio FmNSP/FmNST is greater than or equal to 0.27 and less than or equal to 0.90.

Abstract: The tire (10) for a construction plant vehicle comprises a tread (22) and a crown reinforcement (14) arranged radially on the inside of the tread (22). The crown reinforcement (14) comprises: a protective reinforcement (36) comprising at least one protective ply (42, 44) that exhibits a force at break FmNSP; a working reinforcement (38) comprising at least one working ply (46, 48) that exhibits a force at break FmNST; and a hoop reinforcement (39) comprising at least one hooping ply (40, 41), the hooping ply (40, 41) comprising reinforcing elements known as hoop reinforcing elements, the hoop reinforcing elements making an angle at most equal to 10° with the circumferential direction of the tire (10). The working reinforcement (38) is arranged radially on the inside of the protective reinforcement (36). The ratio FmNSP/FmNST is greater than or equal to 0.27 and less than or equal to 0.90.
