Abstract
A plurality of belt layersare superimposed in a radial direction. The belt layersinclude a plurality of steel cordsarranged in parallel in a row and rubber. The steel cordshave a 1×4 structure in which four filamentsare twisted, and when a center-to-center distance between the steel cordsin at least two of the belt layersadjacent in the radial direction is T, and an average diameter of virtual circumscribed circles of the steel cordshaving the 1×4 structure is D, 1.25≤T/D≤2.25.
