Configure wheels for the BMW M8 F91, F92 and F93

Frequently asked questions: wheels for the BMW M8 F91, F92 and F93

What are the original offsets for the wheels of a BMW M8?

A staggered fitment, according to its Swiss vehicle type records: in 20 inches, 9.5J x 20 at the front and 10.5J x 20 at the rear, both with an offset of 28; in 19 inches, on the coupé and the convertible, 9.5J x 19 with an offset of 26 at the front and 10.5J x 19 with an offset of 28 at the rear. For winter, 9.5J x 19 with an offset of 26 on all four wheels. koleso.ee gives the same values, except 28 for the 19-inch front wheel: the record prevails. [1, 7, 14, 15]

Which tyres, and which load index, does a BMW M8 take?

In 20 inches, 275/35 R20 with load index 102 at the front, i.e. 850 kg per tyre, and 285/35 R20 with load index 104 at the rear, i.e. 900 kg; in 19 inches, 275/40 R19 with load index 105, i.e. 925 kg, and 285/40 R19 with load index 107, i.e. 975 kg. In winter, 265/40 R19 with load index 102 on all four wheels. [7, 15, 19, 20]

What is the load per wheel on a BMW M8?

Its Swiss vehicle type records give the coupé a permissible load of 1,155 to 1,200 kg on the front axle and 1,230 kg on the rear axle, i.e. 577.5 to 600 and 615 kg per wheel; the convertible, 1,180 to 1,215 and 1,260 kg, i.e. 590 to 607.5 and 630 kg per wheel; the Gran Coupé, 1,230 and 1,240 kg, i.e. 615 and 620 kg per wheel. The 275/35 R20 front tyre with load index 102 carries 850 kg. [7, 8, 15, 19, 20]

What PCD, centre bore and bolts does a BMW M8 use?

The PCD is 5x112, the centre bore 66.6 mm, and the wheels are held by M14 x 1.25 bolts tightened to 140 Nm: wheelfitment.eu and koleso.ee give these measurements, SCC the PCD, the centre bore, the thread and the torque, and ThreePiece.us and tirewheelguide.com the PCD, the centre bore and the thread. [1, 2, 3, 4, 5, 6]

Same fixing measurements

As original equipment, these cars have the same PCD, centre bore, thread and fixing as the BMW M8 F91, F92 and F93: PCD 5x112, centre bore 66.6 mm, thread M14 x 1.25, fixing: wheel bolts.

Same fixing measurements; original diameters and offsets: see each car's page. Bolt seat, width and brake clearance: our design office checks them for your car before machining.

Custom forged wheels for the BMW M8 F91, F92 and F93

  • Forged 6061-T6 aluminium
  • 5-axis CNC machining
  • Designed to JWL/VIA standards
  • Fitment worked out for your BMW M8 F91, F92 and F93

M8: 5x112, a 66.6 mm hub, M14 x 1.25 bolts

The BMW M8, as a coupé (F92), a convertible (F91) and a Gran Coupé (F93), M8 or M8 Competition, whose first Swiss vehicle type records date from July 2019, is 5x112 on a 66.6 mm hub, with M14 x 1.25 wheel bolts tightened to 140 Nm: wheelfitment.eu and koleso.ee give these measurements, SCC the PCD, the centre bore, the thread and the torque, and ThreePiece.us and tirewheelguide.com the PCD, the centre bore and the thread, each cited in the table.

A staggered fitment, in 19 and 20 inches

The vehicle type record of the Swiss Federal Roads Office (ASTRA), the document that sets the tyre and wheel combinations a car may carry, permits a staggered fitment for the M8: in 20 inches, 9.5J x 20 at the front, with 275/35 R20 tyres, and 10.5J x 20 at the rear, with 285/35 R20 tyres, both with an offset of 28; in 19 inches, on the coupé and the convertible, 9.5J x 19 with an offset of 26 at the front, with 275/40 R19 tyres, and 10.5J x 19 with an offset of 28 at the rear, with 285/40 R19 tyres. For winter, 9.5J x 19 with an offset of 26 on all four wheels, with 265/40 R19 tyres: it is the only 19-inch wheel in the Gran Coupé's records. koleso.ee gives the same values, except 28 for the 19-inch front wheel: the record prevails.

The load the wheel must carry

The records give the coupé a permissible load of 1,155 to 1,200 kg on the front axle and 1,230 kg on the rear axle, the convertible 1,180 to 1,215 and 1,260 kg, the Gran Coupé 1,230 and 1,240 kg. That is the load the wheel must carry; the tyre keeps at least the load index of the original fitment, 102 and 104 in 20 inches, 105 and 107 in 19 inches (reading a tyre).

What these measurements say about a forged wheel

The offset positions the wheel in the wheel arch: a wider wheel, or a lower offset, brings it closer to the wing. The Onyx Forged design office starts from the measurements on this page, your brakes and your tyres to calculate the width and offset of your wheels, then submits them to you. The offset calculator compares two fitments: it compares, it does not choose the measurement for you.

Roadworthiness test: what is examined

The French roadworthiness test (contrôle technique) examines the wheel without removing it (cracks, deformation, a wheel that protrudes beyond the bodywork) and verifies that the tyre size is one provided for by the manufacturer or accepted as equivalent. Keeping a tyre size from the original fitment, and at least its load index, avoids having to justify it; the details are on the roadworthiness test and registration page.

What we record before machining

Configure your forged wheels for the BMW M8 (F91, F92 and F93)

The Onyx Forged design office works out the measurements of your car from its exact version, stated on the registration document, and shows them to you before machining. Each set is cut from forged 6061-T6 aluminium, machined on a 5-axis CNC centre, as monoblock, two-piece or three-piece wheels; our wheels are designed to JWL/VIA standards. Prices by diameter and the lead time are given on this page, under “What Onyx can make”. Start your configuration or write to contact@onyxforgedwheels.com.
