Fitting wheels on a Audi Q8 e-tron

A Audi Q8 e-tron (from 2023) uses a 5x112 PCD and a centre bore of 66.5 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 66.5 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 66.5 mm.
  • Offset: the original is ET36 to ET38. 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 160 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
  • Tyres: original fitment is 255/55R19, 255/50R20, 265/45R21. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

Vehicles with the same PCD and centre bore

Same 5x112 PCD and same 66.5 mm centre bore: wheels from these vehicles bolt on and centre on a Audi Q8 e-tron without rings. Offset, width, diameter and caliper clearance still need checking.

Frequently asked questions

What is the PCD of a Audi Q8 e-tron?

A Audi Q8 e-tron (from 2023) has a PCD of 5x112: 5 studs or bolts spaced around a circle 112 mm in diameter.

Does a Audi Q8 e-tron need a hub centric ring?

The centre bore (hub diameter) of a Audi Q8 e-tron is 66.5 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 Q8 e-tron?

The recorded original offset is ET36 to ET38 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 Q8 e-tron?

The specified tightening torque is 160 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 Q8 e-tron?

With the same PCD (5x112) and the same centre bore (66.5 mm), these include: Audi A4, Audi RS Q8, Audi RS6 C8, Audi S6 C8. Offset, width and rim diameter still need checking for each vehicle.
