Abstract: A method of verifying the stress rolling of a metallic rim includes the steps of taking a first hardness reading of the surface that is to have been stress rolled, taking a second hardness reading of a reference surface that has not been stress rolled and comparing the readings so that the first hardness reading will be significantly higher than the second only if the surface has been stress rolled.

Abstract: A wheel cover support pedestal is capable of being mounted centrally on a wheel of the type which includes a radial wall having a central hole therethrough. The hole is snuggly received on a circular hub element of an axle when the wheel is mounted on the axle. The hole is defined by an interior periphery of the radial wall to be generally circular with the periphery including a plurality of circumferentially spaced notches to provide a gap between the periphery at each notch and the circular hub element. The wheel cover support pedestal includes a center portion with an element for securing a center section of a wheel cover thereto. A plurality of leg portions extend from the center portion with each leg portion being aligned with one of the notches and including an extended end which is received within a corresponding gap. The extended end has a radially extending foot to make overlying contact with an inboard side of the radial wall adjacent the gap to cause the center portion to be disposed axially outwardly of an outboard side of the radial wall of the wheel when the wheel cover support pedestal is mounted thereon.

Abstract: An improved method of stress rolling a metallic rim includes the additional step of applying an outside force to the rim to produce tensile stress in the region which is being stress rolled to produce a higher resulting compressive stress within the region than could otherwise be obtained through normal stress rolling.
Abstract translation: 对金属边缘进行应力轧制的改进方法包括向边缘施加外力的附加步骤，以在被应力轧制的区域中产生拉伸应力，以在该区域内产生比通过正常情况获得的更高的所得压缩应力 压力滚动。
