so an easy guide is like this:
The good: (enough contact surface area between nuts and wheels)
aftermarket wheel is good with aftermarket nuts.
OEM wheel is good with OEM nuts.
The bad: (not enough? although i never see any hard evidence of failures)
aftermarket wheels arent good with OEM nuts.
OEM wheels arent good with aftermarket nuts.
Why?
just as leek9 said. tapered design on aftermarket, round design on OEM.
