I got a spare 2000 era GM 8 lug 16” PYO alloy yesterday, along with a factory early 90s stainless wheel cover. The stainless wheel cover weighed 1.7 lbs, which isn’t too much but is about 10% of the weight of the wheel. Making pieces from 0.090 Aluminum would weight about the same.
The wheel cover would almost push into the alloy wheel, but the angled in nature of the “flat” part of the wheel kept it from going. It looked like I could bend the little tabs which grip the wheel in slightly and the wheel cover would go on the wheel, but I am a little wary of having it seated in the angled section, as it would seem prone to popping out. The only thing holding it in would be the tabs digging into the finish of the wheels, which I am not crazy about either (corrosion not looks).
This is making me think that I would have to use another attachment method, such as DZUS fasteners. DZUS fastened moon hub caps are available and I know racers who use DZUS wheel covers without issue, so I think I will try to find a way to remove the stock locking tabs and use DZUS fasteners to attach the OEM hubcap to the alloy wheel.
