A pneumatic tire for heavy duty use applications, having at least one sidewall of formed an increased thickness, for providing better tire sidewall wear and increased re-use of the tire's internal carcass, the tire's enhanced thickness sidewall having a relief area formed by at least one radius relief portion adjacent that sidewall's bead to prevent the associated rim flange edge from cutting into the enhanced thickened sidewall, and a sharp angled return sidewall portion adjacent the portion tread sidewall. The increased thickened sidewall, ranging between approximately 2.0 and 3.5 inches, provides maximum thickness in the area of maximum sidewall flexing during use.
