The Effects of Five Basic Design and Construction Parameters on Radial Tire Rolling Resistance and Cornering Force

The Effects of Tire Design/Construction Parameters: Mold Tread Radius, Tread Arc Width to Section Width Ratio, Aspect Ratio, Belt Width to Tread Arc Width Ratio, and Crown Angle were studied. By building tires with combinations of these parameters selected to fulfill the requirements of a designed experiment it was possible to determine the direct and interactive effects of these parameters on rolling resistance and cornering force. The results of these tests, including suggestions for optimum tire design, are discussed.
