Audi A6 Allroad (4GH, C7, 4GJ) Wheel Lug Pattern & Offset Reference
The Audi A6 Allroad (4GH, C7, 4GJ) features specific wheel lug patterns essential for proper wheel fitment. The lug pattern is defined by lug count multiplied by the pitch circle diameter (PCD in mm), which varies across model years. Understanding these specifications ensures compatibility when selecting wheels or tires.\n\nOffset ET and center bore dimensions are crucial for maintaining correct wheel positioning and hub alignment. The A6 Allroad models typically have offset values that balance clearance and handling characteristics, while the center bore size matches the hub diameter to prevent vibrations.\n\nRim sizes for the Audi A6 Allroad (4GH, C7, 4GJ) range within common diameters supporting OEM and aftermarket wheels. Using the correct bolt pattern combined with offset and center bore data will guarantee safe and reliable wheel installation.\n\nFor ease of reference, a year-sorted table of these wheel specifications is available to help owners and professionals verify the correct lug pattern, offset, center bore, and rim size, facilitating proper wheel selection and fitment.
