Assuming a properly centered wheel, most of the force is transmitted through the clamped faces of the wheel and hub, by friction. Also torsionally through the bolts, but much less so. Proper lug nut tightness is critical for that friction. The hub centric lips are there to center the wheel, not to carry load. raymond howard md rome ga
