The thickness of the rubber between the adjacent steel cords is in a range between 0.80 and 2.00 mm when measured in a tire circumferential direction at a location having a tire maximum width in an arrangement of the steel cords in the carcass cord layer. A product (nxd.sup.4) between a number (m) of the filament yarns constituting the steel cord of the single strand construction and a diameter (d) of the filaments is in a range of 0.002 to 0.012. The diameter of the filaments is in a range between 0.15.ltoreq.d.ltoreq.0.25 mm.
