Frequently asked questions: wheels for the Audi R8 42

What are the original offsets for the wheels of an Audi R8 type 42?

A staggered fitment, according to its Swiss vehicle type records: 8.5J with an offset of 42 at the front; at the rear, 11J x 19 with an offset of 50, or 10.5J x 18 with the same offset on the 4.2 FSI. [4, 9]

Which tyres, and which load index, does an Audi R8 type 42 take?

In 19 inches, 235/35 R19 with a load index of 91 at the front, i.e. 615 kg per tyre, and 295/30 R19 with an index of 100, i.e. 800 kg, or 305/30 R19 with an index of 102, i.e. 850 kg, at the rear; in 18 inches on the 4.2 FSI, 235/40 R18 with an index of 95 and 285/35 R18 with an index of 101. [4, 9, 13, 14]

What PCD, centre bore and bolts does an Audi R8 type 42 use?

The PCD is 5x112, the centre bore 57.1 mm, and the wheels are held by M14 x 1.5 wheel bolts, according to koleso.ee and SCC. The tightening torque is not published: only one of the sources read gives it. [1, 2, 3]

Same fixing measurements

As original equipment, these cars have the same PCD, centre bore, thread and fixing as the Audi R8 42: PCD 5x112, centre bore 57.1 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 R8 42

  • Forged 6061-T6 aluminium
  • 5-axis CNC machining
  • Designed to JWL/VIA standards
  • Fitment worked out for your Audi R8 42

Audi R8 type 42: 5x112, a 57.1 mm hub, M14 x 1.5 bolts

The first-generation Audi R8 (type 42), as a coupé and as a Spyder, with the 316 kW 4.2 FSI V8 engine or the 386 to 419 kW 5.2 FSI V10, is 5x112 on a 57.1 mm hub, with M14 x 1.5 wheel bolts: koleso.ee and SCC give these measurements, each cited in the table. Only one of the sources read gives the tightening torque: we do not publish it. The R8 4S that succeeds it has its own page.

An 18 and 19-inch staggered fitment

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 R8, according to its records of December 2013 to June 2014: at the front, 8.5J with an offset of 42; at the rear, 11J x 19 with an offset of 50, with 295/30 R19 or 305/30 R19 tyres. On the 4.2 FSI, the record also permits 18 inches: 8.5J x 18 at the front and 10.5J x 18 at the rear, with the same offset of 50.

The load the wheel must carry

The engine sits behind the seats: the rear carries the most, and the permissible load per axle varies with the engine and the body style. The tyre keeps at least the load index of the original fitment, 91 at the front and 100 or 102 at the rear in 19 inches (reading a tyre). The braking system limits the smallest possible wheel diameter: the guide wheels and brakes explains why.

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 R8 (type 42)

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.
