BMW Z4 Wheel Lug Pattern, Offset ET, Center Bore & Rim Sizes Reference
The BMW Z4 features specific wheel lug patterns defined by lug count and pitch circle diameter (PCD) that vary by model year. Understanding these specifications is crucial for proper wheel fitment and safe driving.\n\nWheel offset (ET) and center bore dimensions are equally important when selecting wheels for BMW Z4 to ensure compatibility with suspension components and hub assemblies. Offset affects the wheel's position relative to the suspension, while the center bore must match the vehicle hub diameter for precise mounting.\n\nThis reference page provides a year-sorted table of BMW Z4 wheel lug patterns, offset ET values, center bore sizes, and compatible rim diameters. Use this information to select OEM or aftermarket wheels correctly, avoiding fitment issues or safety risks.
