Fitting wheels on a Audi A6 C6

A Audi A6 C6 (2004–2011) uses a 5x112 PCD and a centre bore of 57.1 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

  • PCD: 5x112 required. See all vehicles with 5x112.
  • Centre bore: the wheel must have a centre bore of 57.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 57.1 mm.
  • Offset: the original is ET35 to ET48. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
  • Fixings: thread M14x1.5, tightened to 120 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
  • Tyres: original fitment is 205/60R16, 225/50R17, 245/45R17, 245/40R18. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

Generations of the Audi A6

Previous generation: Audi A6 (1994–1997) — same 5x112 bolt pattern and same centre bore: original wheels swap between the two generations; check offset and diameter. Next generation: Audi A6 C7 (2011–2018) — same 5x112 bolt pattern, but the centre bore goes from 57.1 to 66.5 mm: hub ring one way, no fit the other way.

Vehicles with the same PCD and centre bore

Same 5x112 PCD and same 57.1 mm centre bore: wheels from these vehicles bolt on and centre on a Audi A6 C6 without rings. Offset, width, diameter and caliper clearance still need checking.

Frequently asked questions

What is the PCD of a Audi A6 C6?

A Audi A6 C6 (2004–2011) has a PCD of 5x112: 5 studs or bolts spaced around a circle 112 mm in diameter.

Does a Audi A6 C6 need a hub centric ring?

The centre bore (hub diameter) of a Audi A6 C6 is 57.1 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.

What offset (ET) for a Audi A6 C6?

The recorded original offset is ET35 to ET48 depending on the version and wheel size. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.

What tightening torque for the wheels of a Audi A6 C6?

The specified tightening torque is 120 Nm for M14x1.5 fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.

Which vehicles have the same PCD as a Audi A6 C6?

With the same PCD (5x112) and the same centre bore (57.1 mm), these include: Audi Q4 E-TRON, Audi RS3 8Y, Audi A3 8Y, Audi S3 8Y. Offset, width and rim diameter still need checking for each vehicle.
