by second conical surface 86 such that another barbed and stepped transition exists at second back face 108 third conical surface 88 also extends at an included angle c of approximately 8 3 u00b0 to a third back face 112 fourth conical surface 90 also extends at a similar included angle d of 8 3 u00b0 to a fourth back face 114 fourth conical surface 90 includes a minimum diameter portion at a circle 120 having a diameter less than the maximum diameter portion of third conical surface 88 a similar stepped arrangement exists between fourth conical surface 90 and fifth conical surface 92 fifth conical surface 92 extends at an included angle e of approximately 5 6 u00b0 it is contemplated that the minimum diameter defined by first conical surface 84 at circle 100 is less than the minimum inner diameter of wall 22 furthermore at least one of the conical surfaces 84 86 88 90 92 includes an outer diameter that is greater than the inner diameter of wall 22 based on the direction of insertion the tapered conical surfaces and the fact that sleeve 54 is constructed from a hardened steel the non ferrous material of wheel 10 displaces to allow insertion of sleeve 54 within aperture 20 sleeves 54 are inserted within apertures 20 and driven to a final seated position through the use of a press and or lug nuts 56 during initial sleeve to wheel installation sleeves 54 continue to be axially translated until surface 80 engages land 26 during the axial translation at least one of conical surfaces 84 86 88 90 92 engages tapered wall 22 of aperture.
