ABSTRACT:
A tire for a vehicle wheel includes at least one metallic reinforcing cord comprising a single strand of elementary filaments preformed by sinusoidal waving and wound together. The number of filaments is greater than or equal to 3 and less than or equal to 8. A diameter of each filament is greater than or equal to 0.12 mm and less than or equal to 0.35 mm. A linear density of the at least one reinforcing cord is greater than or equal to 0.18 g/m and less than or equal to 4.0 g/m. A value of a breaking-stress integral of the at least one reinforcing cord is greater than or equal to 5,000 J/m3. In a two-wheeled vehicle, the at least one reinforcing cord in a tire for front-mounting may be distributed with a variable density while, in a tire for rear-mounting, the density may be constant.
