Abstract
A molded shape for an earthmover tire 20 is disclosed. The uninflated, unmounted outer shape tire's sidewalls 22 are composed entirely of curves connected at tangency points between the tread 24 and the bead flange area 26. The shape transitions smoothly from one curve to the next without any flat surfaces. The sidewalls 22 have axially outer convex surfaces extending from the tread 24 to the bead flange area 26. The tread 24 has a radially outer ground contacting surface 28. A curved line tangent to the ground contacting surface 28 forms an arc having a single radius of curvature (TR). In a preferred embodiment of the invention, the outer shape consists of four curves with one curve describing the tread arc width (TAW), one curve R.sub.us describing the upper sidewall, one curve R.sub.ls describing the lower sidewall, and one curve describing the flange area radius R.sub.fa.
