Expert Buying Guide for 2002 Mercury Cougar
For your 2002 Mercury Cougar, the bolt pattern is 4x108 with a 63.4mm center bore. When selecting aftermarket wheels, ensure the center bore matches or use hub-centric rings to prevent vibration. The offset is sensitive; stick to 35-45mm to avoid rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.5) and seat type (conical/60-degree) to ensure proper clamping force. Mismatched lug nuts can lead to wheel loss. Verify that the wheel's load rating meets or exceeds the vehicle's requirements. This final year of the 4x108 pattern shares compatibility with 1999-2002 Cougars.
