By using the lugs to center your wheels, you would be carrying the entire load of your truck and what ever you are hauling on them, you risk the wheels coming loose and over loading the studs and causing catastrophic failure. On our trucks, the center hub is designed to carry the load not the studs. The studs just keep the wheels tight to the hubs from spinning on the hubs. If you haul heavy, I would recommend you using the properly fitting wheels, not some generic will fits.
