Fitting wheels on a Audi Ur-Quattro

A Audi Ur-Quattro (1980–1991) 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 ET25. 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 M14x1.50, tightened to 120 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.

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 Ur-Quattro without rings. Offset, width, diameter and caliper clearance still need checking.

Same PCD, different centre bore

These vehicles also use 5x112 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 57.1 mm, and will not fit if it is smaller.

Frequently asked questions

What is the PCD of a Audi Ur-Quattro?

A Audi Ur-Quattro (1980–1991) has a PCD of 5x112: 5 studs or bolts spaced around a circle 112 mm in diameter.

Does a Audi Ur-Quattro need a hub centric ring?

The centre bore (hub diameter) of a Audi Ur-Quattro 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 Ur-Quattro?

The recorded original offset is ET25. 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 Ur-Quattro?

The specified tightening torque is 120 Nm for M14x1.50 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 Ur-Quattro?

With the same PCD (5x112) and the same centre bore (57.1 mm), these include: Audi Q4 E-TRON, Audi A3 8Y, Audi RS Q3, Audi SQ2. Offset, width and rim diameter still need checking for each vehicle.
