Expert Buying Guide for 1998 Lincoln Mark VIII
For your 1998 Lincoln Mark VIII, the bolt pattern is 5x108 with a 63.4mm center bore. When selecting aftermarket wheels, ensure hub-centric rings are used to match the bore precisely, preventing vibrations. The offset is critical; stock is 40mm, but a range of 35-45mm is acceptable for proper clearance. Avoid offsets below 30mm to prevent rubbing. Lug nuts must be 12x1.50 with a conical (60-degree) seat; using incorrect seat type can cause wheel loosening. Always verify lug nut torque to 100 ft-lbs and re-torque after 50 miles. This final year of the 5x108 Mark VIII shares compatibility with 1993-1998 models, but aftermarket wheels may require hub rings.

PCD stands for Pitch Circle Diameter, which is the same as the bolt pattern. For the 1998 Mark VIII, the PCD is 5x108.
How tight should I torque the lug nuts on a 1998 Lincoln Mark VIII?
Refer to your owner's manual for exact specs, but always tighten the N 12x1.50 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
