摘要:
A cord of a band of a tire has a single-stranded structure in which steel filaments are stranded, and the number of the filaments is not less than three and not greater than six. In a cross-section of the cord, when φ represents a diameter of a smallest circle that surrounds cross-sections of the filaments, and ψ represents a diameter of each filament, a gap is formed between the filaments such that the diameter φ is not less than three times the diameter ψ and not greater than six times the diameter ψ in the case of the number of the filaments being three or four. An initial elongation of the cord is not less than 0.1% and not greater than 1.5%.
