Abstract
A wheel rim including a flange profile on a tire side of an open end flange of the wheel rim, the flange profile defined by the equation: y 1 = ( a Theta 1 + 1 ( 1 + Exp ( a Theta 3 + a Theta 4 · X 1 ) ) aTheta 5 ) · a Theta 2 wherein, for 0≤X1≤1, aTheta1 is between −1.004 to −0.974, aTheta2 is between −−1.049 to −1.0182, aTheta3 is between −3.601 to −2.760, aTheta4 is between 18.791 to 25.965, and aTheta5 is between 0.185 to 0.277.
