Claim:
1. A tire cord fabric for use as cap ply on the top of the belt layers of a passenger vehicle tire as wound strips having a width of 5 to 25 mm with angles of 0 to 5 degrees to the circumferential plane of the tire and which enables using less rubber and higher cord content in a given cord-rubber composite volume and eliminates the disadvantages of an excessive rubber content, comprising: paired cords used as warps, in which the single cords are connected to each other as pair by RFL adhesive and the number of the paired cords in 10 cm is between 25 and 110 (50 to 220 single cords/10 cm); and SZ or ZS type opposite twisted paired cords having lower angular shear property within and between the paired cords compared to the conventional applications in cases of tension, compression and bending; wherein the paired cord comprising two cords one of which has unbalanced twist applying residual torque towards the other cord, whereas the other cord therein, having no residual torque, has balanced twist.
