Will wheels from another Pontiac fit my 1993 LeMans?

Why is matching the 56.6mm center bore important for the 1993 LeMans?
The 56.6mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.

Refer to your owner's manual for exact specs, but always tighten the M12x1.5 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
