The invention relates to a nylon cord thread and a tire adopting the same, and belongs to the field of tires. The nylon cord thread at least comprises two strands of nylon 66 protofilaments; each strand of nylon 66 protofilament is firstly subjected to primary twisting to form strand filament; the strand filaments are stranded and subjected to secondary twisting to form the nylon cord thread; the strength-diameter ratio K of the nylon cord thread is larger than or equal to 480; and the diameter d of the nylon cord thread is larger than or equal to 0.9 mm. The invention further discloses a tire body prepared from the nylon cord thread or a force-bearing component in a belted layer and the tire manufactured from the force-bearing component. The nylon cord thread has the beneficial effects that the specific strength Q of a cord fabric formed by the cord thread is larger than or equal to 370 N/mm, and the harsh light weight requirement of the tire can be met.
