Fitting wheels on a Alpina B10

A Alpina B10 (1988–1996) uses a 5x120 PCD and a centre bore of 72.6 or 74.1 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

  • PCD: 5x120 required. See all vehicles with 5x120.
  • Centre bore: the wheel must have a centre bore of 72.6 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 72.6 mm.
  • Offset: the original is ET12 to ET20. 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 M12x1.50, tightened to 115 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
  • Tyres: original fitment is 235/45R17, 235/40R18. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

Vehicles with the same PCD and centre bore

Same 5x120 PCD and same 72.6 mm centre bore: wheels from these vehicles bolt on and centre on a Alpina B10 without rings. Offset, width, diameter and caliper clearance still need checking.

Frequently asked questions

What is the PCD of a Alpina B10?

A Alpina B10 (1988–1996) has a PCD of 5x120: 5 studs or bolts spaced around a circle 120 mm in diameter.

Does a Alpina B10 need a hub centric ring?

The centre bore (hub diameter) of a Alpina B10 is 72.6 or 74.1 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 Alpina B10?

The recorded original offset is ET12 to ET20 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 Alpina B10?

The specified tightening torque is 115 Nm for M12x1.50 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 Alpina B10?

With the same PCD (5x120) and the same centre bore (72.6 mm), these include: Alpina B4 axe arrière, Alpina B4 axe avant, Alpina B3, Alpina D3. Offset, width and rim diameter still need checking for each vehicle.
