Abstract: An insert rubber for improving aerodynamics of a tire and an installation method thereof, and provides an insert rubber for improving aerodynamics of a tire and an installation method thereof, in which, by eliminating a space which is located between a bead of a tire and a flange of a rim, airflow is prevented from being introduced between the bead and the flange while a vehicle travels, and the space between the bead and the flange is filled with the insert rubber, thereby preventing turbulence from being generated in the space between the bead and the flange.

Abstract: A metal wheel which produces an unusual visual effect when rotated employs a disc member extending between a center hub and outermost rim in angular relationship to the wheel's axis of rotation. The rim is provided with a continuously varied weighting feature to neutralize the centrifugal imbalance that would otherwise be produced.

Abstract: A wheel having a hub centered upon an axis of rotation is provided with a disc member extending outwardly from the hub and centered upon a plane that intersects the axis at an angle between 47 and 87 degrees and terminates in a rim member having a radially measured thickness which progressively varies between diametrically opposed thick and thin regions which are in reversed relationship on opposed surfaces of the wheel.
