Abstract
Abstract The plastic wheel cover has an annular cylindrical slot on the side thereof to face the wheel. The metal lockring has grip fingers that are pushed into the annular slot and grip an inner surface of the slot to hold the lockring from loosening. The lockring has alternating longer and shorter spring fingers with bent back lips to grip the inner surface of the tire bearing rim of the wheel. At equiangularly spaced points there are webs interconnecting the outer and inner cylindrical flanges of the wheel cover that form the cylindrical slot, to reinforce said flanges. Said wheel cover also has equiangularly spaced lugs outside of said annular slot to engage the tire rim for positioning the cover in correct coaxial and axial relation to the rim.
