Expert Buying Guide for 1998 Ford Expedition
For your 1998 Ford Expedition, the 5x135 bolt pattern is shared with 1997–2003 models, ensuring cross-compatibility. The 87.1mm center bore requires hub-centric rings when installing aftermarket wheels to prevent vibration and ensure proper load distribution. Offset is critical: the factory 10mm offset should be maintained within ±5mm to avoid rubbing or suspension interference. Always use lug nuts with the correct thread pitch (12x1.75) and seat type—factory wheels use a cone seat; aftermarket wheels may require ball or flat seats. Mismatched lug nuts can cause wheel separation. Re-torque after 50 miles of driving.
