Abstract
A thin gauge, fine diameter steel cord reinforced tire ply fabric 2 is lap spliced. The steel cord 1 has one or more filaments 9, and each filament has a percent elongation of over 2.5% and tensile strength of at least (-2000D+4400 MPa).times.95%, where D is the diameter of the filament in millimeters. For passenger and lightly loaded trucks the fabric 2 is manufactured using a preferred cord 1 which is a 1+5.times.0.18 mm cord spaced 14 ends per inch, and for heavier loaded vehicles such as light trucks load rated E or greater the number of cords 1 is increased to 28 ends per inch. The fabric 2 has a gauge thickness g in the range of the cord diameter C+0.22 mm to C+1.25 mm.
