Which tend to fly off?
Originals or aftermarket i forget which ones tend to fly off? thx!

 

I'd think aftermarket hubcaps would be the ones that fly off. I had OE wheel covers and OE poverty hubcaps on my 64 98 (not at the same time) and never lost one.

 

I have not heard reports of either version “flying off”. Now I’m curious.. Perhaps if someone used the wrong wheels, the retainment ring would have incorrect dimensions..

 

Not sure of the answer to the question, but I would think that the oringials would hold fast!

Speaking of which, I just so happen to have a VERY nice set of poverty caps available, if you are looking...
here's a stock photo of what they look like...
