Buick Century Wheel Lug Pattern, Offset, and Center Bore Reference
The Buick Century wheel lug pattern data is essential for selecting compatible aftermarket wheels or replacements. Each model year features specific lug count and pitch circle diameter (PCD) measurements, critical for proper mounting. Typically, the Buick Century uses a 5-lug pattern combined with an accurate PCD to ensure the wheel fits securely.\n\nOffset (ET) values vary by year and trim, affecting wheel position relative to the hub and suspension components. Correct offset ensures proper clearance and handling characteristics. The center bore diameter is equally important to center the wheel on the hub, preventing vibrations.\n\nCommon rim sizes for the Buick Century range from 14 to 16 inches, depending on the production year and model variant. This comprehensive lug pattern catalog provides year-sorted Buick wheel specifications, allowing users to confirm bolt pattern, offset, and center bore measurements for accurate fitment and safety on the road.
