Fitting wheels on a Alpina B5

A Alpina B5 (from 2017) uses a 5x112 PCD and a centre bore of 66.6 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 66.6 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 66.6 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 M14x1.25, tightened to 120 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
  • Tyres: original fitment is 255/35R20. 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 66.6 mm centre bore: wheels from these vehicles bolt on and centre on a Alpina B5 without rings. Offset, width, diameter and caliper clearance still need checking.

Frequently asked questions

What is the PCD of a Alpina B5?

A Alpina B5 (from 2017) has a PCD of 5x112: 5 studs or bolts spaced around a circle 112 mm in diameter.

Does a Alpina B5 need a hub centric ring?

The centre bore (hub diameter) of a Alpina B5 is 66.6 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 Alpina B5?

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 Alpina B5?

The specified tightening torque is 120 Nm for M14x1.25 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 Alpina B5?

With the same PCD (5x112) and the same centre bore (66.6 mm), these include: Alpina B4, Alpina XB7, Alpina XD3, Alpina XD4. Offset, width and rim diameter still need checking for each vehicle.
