Take a wheel off and look. The tapered lugnut will damage a bare aluminum lug hole. Do the wheels have tapered steel inserts that match the taper of the lugnuts? Or are the lug holes much larger than the studs? If the holes are larger than the studs, you need the nuts with the sleeve that extends through the wheel and washers that go in the counterbore on the outer face of the wheel.
