The stock rims and lugs are designed differently than aftermarket lugs and rims. The big flat washer type area on the stock lugs is what is doing all of the work holding the rim on. When you take that away by using an aftermarket lug, the amount of rim that the lugs are actually holding onto is too thin. Kinda hard to explain, but here is what happens...



Aftermarket rims have much more material between the acorn part of the lug and the hub.
