AUDI A6 Wheel Lug Pattern, Offset ET & Center Bore Reference
The AUDI A6 features specific wheel lug patterns essential for correct wheel installation and safe driving. These patterns include the lug count and pitch circle diameter (PCD) in millimeters, which vary by model year. Along with lug pattern, offset (ET) and center bore measurements define the wheel fitment and clearance.\n\nTypically, AUDI A6 models use a 5-lug pattern with common PCD values such as 112 mm. Offset ET ranges generally between ET30 and ET45, influencing the wheel's positioning relative to the suspension components. Center bore size is commonly 66.5 mm, ensuring proper hub centering.\n\nRim sizes for the AUDI A6 fluctuate across production years, with popular diameters from 16 to 20 inches. Selecting the appropriate lug pattern, offset, center bore, and rim diameter is crucial when replacing or upgrading wheels to maintain driving performance and safety.\n\nFor precise wheel fitment, always verify the year-specific AUDI A6 lug pattern, offset, center bore, and rim size data to avoid mismatches and ensure compatibility with OEM specifications.
