A pneumatic tire construction is provided using one or more folded body ply sheets constructed such that upon formation of the tire, the turn-ups in the sidewalls are looped turn-ups such that there are no free turn-up ends in the sidewalls.

A method of designing a tire, wherein a tire designer identifies a target residual aligning torque range for a tire design and creates a computer model of the tire, including a buttress angle. Further, the method includes calculating the residual aligning torque of the modeled tire and comparing the calculated residual aligning torque value to the target residual aligning torque to determine whether the calculated residual aligning torque value is within the target residual aligning torque range. The method produces a final tire design having a target residual aligning torque.
