    Abstract: The instant invention is a high-density polyethylene composition, method of producing the same, articles made therefrom, and method of making such articles. The high-density polyethylene composition of the instant invention includes a first component, and a second component. The first component is a high molecular weight ethylene alpha-olefin copolymer having a density in the range of 0.915 to 0.940 g/cm3, and a melt index (I21.6) in the range of 0.5 to 10 g/10 minutes. The second component is a low molecular weight ethylene polymer having a density in the range of 0.965 to 0.980 g/cm3, and a melt index (I2) in the range of 50 to 1500 g/10 minutes. The high-density polyethylene composition has a melt index (I2) of at least 1, a density in the range of 0.950 to 0.960 g/cm3, and g′ of 1.

    Abstract: A vehicle wheel well assembly is provided and is adapted to engage a vehicle floor pan. The wheel well assembly includes a floor and an annular sidewall extending upwardly from the periphery of the floor. A post extends upwardly from the center of the floor for engaging the spare wheel assembly. A threaded connector extends upwardly from the post for threaded engagement with a receptacle on a top. The sidewall terminates in either a mounting flange or a deck. When connected to a deck, the deck includes a mounting flange. The floor and sidewalls are integrally formed preferably of a composite material. A storage space is created in the area of the post. A method of securing a vehicle wheel well assembly in a vehicle is also provided.
