Expert Buying Guide for 1994 Mercury Cougar
For your 1994 Mercury Cougar, the 5x108 bolt pattern is shared with 1992–1997 models, ensuring cross-compatibility. The 63.4mm center bore requires hub-centric rings for aftermarket wheels to prevent vibration. Offset is sensitive: stick to 35-45mm range to avoid rubbing or clearance issues. Always use 12x1.5 lug nuts with the correct seat (conical 60° for most aftermarket wheels, ball seat for factory). Improper lug nut seating can cause wheel loss. Verify wheel load rating meets or exceeds vehicle specifications.
