Audi A6 wheel fitment — C5
Overview
The Audi A6 C5 is an executive car manufactured by Audi AG, succeeding the C4 generation and preceding the C6. It was introduced in February 1997 based on the Volkswagen Group C5 platform and made its debut at the 1997 Geneva Motor Show. The C5 was available as a saloon (sedan) and Avant (estate/wagon), competing with models like the BMW 5 Series and Mercedes-Benz E-Class. It featured a redesigned body with improved aerodynamics, offering a drag coefficient of 0.28. Engine options included petrol V6 engines ranging from 2.4 to 4.2 liters, diesel variants, and later in its lifecycle, more powerful versions like the S6 and RS 6. The C5 was also notable for introducing Audi's multitronic continuously variable transmission (CVT) on some models.

Start with the hub. The Audi A6 C5 spec table gives the bolt pattern and bore; the second table is the aftermarket window for Audi A6 wheel fitment.
| Bolt pattern (PCD) | 5x112 |
| Centre bore | 57.1 mm |
| Bolt / thread | M14x1.5 (bolts) |
| Wheel-bolt torque | 120 Nm |
| Seat type | radius |

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 6J–8.5J | ET15–ET45 |
As a rule, each extra 1J of width wants roughly +8 to 10 ET to keep the wheel tucked. The exact offset and any spacer are confirmed by the fit-check.
UK popularity & demand
Based on DfT VEH0124 vehicle-parc data (2025), there are approximately 128,620 Audi A6 on UK roads, placing it in the top 3% of car models by volume across our fitment database.
That makes Audi A6 wheel fitment a high-demand spec to keep in stock. It is one reason we track it here.
