A tire casing, has an unvulcanized noncord reinforced subassembly 10A as an intermediate article of manufacture. The subassembly 10 has at least two components laminated to it. The components are selected from one or more of the component types consisting of a liner 50, sidewall 70, a chafer 60, a whitewall strip 80, a cover strip 90, and a gum shoulder strip 40. The subassembly 10A has a width (W) and a pair of ends 12,14, the distance between the ends 12,14 defining the subassembly length (L). Preferably, the components are laminated to one another and have common ends 12,14 that are spliced along a substantially flat plane (P). The flat plane (P) extends through the article across its axial width, preferably substantially perpendicular to the length of the subassembly. The flat plane (P) is inclined at an angle theta, theta being less than 90°, preferably about 80° relative to a radial normal plane (NP) passing through and perpendicular to the subassembly 10A. Each end 12,14 has a plurality of closely spaced ridges 81 and valleys 82 of a depth of less than one half the diameter (d) of the cold wire used to form the undulating substantially flat planar end surfaces 12,14. |
