If the wheel is rolling, the force is perpendicular to the direction of the hoop which causes the hoop to turn.
But how? All the forces you have described are acting along the same vertical plane that the axle lies on and that is perpendicular to the direction of travel. how can this 2-dimensional set of forces cause motion (yaw) in the third dimension?
