Expert Buying Guide for 1994 Oldsmobile 98
For your 1994 Oldsmobile 98, the bolt pattern is 5x115 with a center bore of 70.3mm. When selecting aftermarket wheels, ensure the center bore matches or use hub-centric rings to prevent vibration and ensure proper load distribution. The offset is critical: stick to 47mm ±5mm to avoid rubbing or clearance issues with suspension and body components. Always use lug nuts with the correct thread pitch (12x1.5) and seat type—factory wheels use a conical (60-degree) seat. Never mix seat types; improper seating can cause wheel loosening. Safety first: verify all specs before installation.
