Frequently asked questions: wheels for the Audi RS Q8 4M

What are the original offsets for the wheels of an Audi RS Q8?

According to its Swiss vehicle type records, two wheels, each the same on all four corners: 10J x 22 and 10.5J x 23, both with an offset of 18. koleso.ee gives the same values; ThreePiece.us gives 20 for the 22-inch wheel, and the record prevails. For winter, the records permit the same wheels. [1, 3, 6, 12]

Which tyres, and which load index, does an Audi RS Q8 take?

295/40 R22 with load index 112, i.e. 1120 kg per tyre, or 295/35 R23 with load index 108, i.e. 1000 kg, on all four wheels. In winter, 275/40 R22 with load index 107, i.e. 975 kg, or 295/35 R23 with load index 108. [6, 12, 13, 14]

What is the load per wheel on an Audi RS Q8?

Its Swiss vehicle type records give it a permissible load of 1,600 kg on the front axle and 1,630 kg on the rear axle, i.e. 800 and 815 kg per wheel. The 295/35 R23 tyre with load index 108, the one with the lowest load capacity among its fitments, carries 1000 kg. [6, 12, 13, 14]

What PCD, centre bore and bolts does an Audi RS Q8 use?

The PCD is 5x112, the centre bore 66.5 mm, and the wheels are held by M14 x 1.5 bolts tightened to 160 Nm: wheelfitment.eu, koleso.ee and SCC give these measurements; ThreePiece.us and tirewheelguide.com give the PCD, the centre bore and the thread. [1, 2, 3, 4, 5]

Same fixing measurements

As original equipment, these cars have the same PCD, centre bore, thread and fixing as the Audi RS Q8 4M: PCD 5x112, centre bore 66.5 mm, thread M14 x 1.5, 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 Audi RS Q8 4M

  • Forged 6061-T6 aluminium
  • 5-axis CNC machining
  • Designed to JWL/VIA standards
  • Fitment worked out for your Audi RS Q8 4M

RS Q8 4M: 5x112, a 66.5 mm hub, M14 x 1.5 bolts

The Audi RS Q8 of the 4M generation, whose first Swiss vehicle type records date from December 2019, is 5x112 on a 66.5 mm hub, with M14 x 1.5 wheel bolts tightened to 160 Nm: wheelfitment.eu, koleso.ee and SCC give these measurements, and ThreePiece.us and tirewheelguide.com the PCD, the centre bore and the thread, each cited in the table; hubcentric-rings.com gives 66.6 mm for the Audi Q8, without naming the RS Q8.

Two wheels, 22 and 23 inches, with the same offset

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 two wheels for the RS Q8, each the same on all four corners: 10J x 22 with 295/40 R22 tyres and 10.5J x 23 with 295/35 R23 tyres, both with an offset of 18. For winter, it permits the same wheels, with 275/40 R22 or 295/35 R23 tyres. koleso.ee gives the same values; ThreePiece.us gives an offset of 20 for the 22-inch wheel, and the record prevails.

The load the wheel must carry

The record gives a permissible load of 1,600 kg on the front axle and 1,630 kg on the rear axle, i.e. 800 and 815 kg per wheel. That is the load the wheel must carry; the tyre must keep at least the load index of the original fitment, 112 in 22 inches and 108 in 23 inches (reading a tyre). The guide wheels for a heavy car: the load per wheel explains how to read it.

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 Audi RS Q8 (4M)

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.
