A pneumatic tire comprising:
- a belt structure and a torus shaped carcass having a first inner radius and an outer radius, a first and second sidewall, wherein the carcass is comprised of three or more layers of ply, wherein at least one layer of ply is formed from a rubberized strip of one or more cords, the strip being wound in a geodesic pattern and having the one or more cords extend across the carcass from a first shoulder to a second shoulder in a path that has at least one point tangent to the first inner radius located in a bead area of the tire, wherein a first column bead is positioned between an inner liner and the first layer of ply, wherein the one or more cords are defined by the equation ρ [cos α]n=K, where n is a positive real number greater than 0.1 and less than 1, and K is a constant.
