AUDI A7 Wheel Lug Pattern, Offset ET, and Center Bore Specifications

The AUDI A7 wheel lug pattern defines the essential mounting specifications, expressed as lug count multiplied by the PCD (pitch circle diameter in millimeters). For accurate wheel fitment, the common AUDI A7 lug pattern is 5×112 mm, ensuring compatibility with various aftermarket and OEM rims.\n\nWheel offset, represented by the ET value, is crucial for maintaining proper clearance and handling characteristics on the AUDI A7. Typical ET values range from ET30 to ET45 depending on the model year and rim width, affecting wheel position relative to the suspension and fenders.\n\nCenter bore size guarantees that the wheel hubs correctly center on the vehicle’s axle. For the AUDI A7, the standard center bore is 66.6 mm, which facilitates a secure and vibration-free fitment.\n\nUnderstanding rim size variations, including diameter and width, helps in selecting wheels that match the A7’s performance and style requirements. Common sizes span from 18 to 21 inches depending on model year and trim, providing options for both factory and custom setups.
