Configure wheels for the Audi R8 4S

Frequently asked questions: wheels for the Audi R8 4S

What are the original offsets for the wheels of an Audi R8 4S?

A staggered fitment, according to its Swiss vehicle type records: in 20 inches, 8.5J x 20 with an offset of 42 at the front and 11J x 20 with an offset of 47 at the rear; in 19 inches, 8.5J x 19 with an offset of 42 at the front and 11J x 19 at the rear, for which the record permits two offsets, 44 or 50: its box is left empty. For winter, a 10.5J x 19 rear wheel with an offset of 55. koleso.ee gives the same wheels and the same front offset; at the rear, it gives 50 for the original fitment in 19 as in 20 inches, whereas the records give 47 in 20 inches: the record prevails. [1, 8, 18]

Which tyres, and which load index, does an Audi R8 4S take?

In 20 inches, 245/30 R20 with load index 90 at the front, i.e. 600 kg per tyre, and 305/30 R20 with load index 103 at the rear, i.e. 875 kg; in 19 inches, 245/35 R19 with load index 93, i.e. 650 kg, and 295/35 R19 with load index 104, i.e. 900 kg. [8, 18, 19, 20]

What is the load per wheel on an Audi R8 4S?

Its Swiss vehicle type records give it, depending on the version and the body style, a permissible load of 870 to 960 kg on the front axle and 1,100 to 1,195 kg on the rear axle, i.e. 435 to 480 kg per front wheel and 550 to 597.5 kg per rear wheel: the engine is mid-mounted, so the rear carries the most. The 305/30 R20 rear tyre with load index 103 carries 875 kg. [8, 11, 14, 19, 20]

What PCD, centre bore and bolts does an Audi R8 4S use?

The PCD is 5x112 and the wheels are held by M14 x 1.5 bolts. The centre bore is not the same on both axles: 57.1 mm at the front and 66.5 mm at the rear, according to koleso.ee, tirewheelguide.com and SCC; wheelfitment.eu gives 57.1 mm for both. The tightening torque is not published: the sources we have read do not agree. [1, 2, 3, 4, 5, 6, 7]

Custom forged wheels for the Audi R8 4S

  • Forged 6061-T6 aluminium
  • 5-axis CNC machining
  • Designed to JWL/VIA standards
  • Fitment worked out for your Audi R8 4S

R8 4S: 5x112, two centre bores, M14 x 1.5 bolts

The Audi R8 of type 4S, whose first Swiss vehicle type record dates from October 2015, is 5x112, with M14 x 1.5 wheel bolts: wheelfitment.eu, koleso.ee, ThreePiece.us and SCC give these measurements, and tirewheelguide.com the PCD and the thread, each cited in the table. Its hub does not have the same diameter on both axles: 57.1 mm at the front and 66.5 mm at the rear, according to koleso.ee, tirewheelguide.com and SCC; wheelfitment.eu gives 57.1 mm for both. The hub table, which has only one box for both axles, leaves the centre bore empty; both values are in the questions and answers. The sources we have read do not agree on the tightening torque: we do not publish it.

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 for the R8 a staggered fitment, wider at the rear: in 20 inches, 8.5J x 20 with an offset of 42 at the front, with 245/30 R20 tyres, and 11J x 20 with an offset of 47 at the rear, with 305/30 R20 tyres; in 19 inches, 8.5J x 19 with an offset of 42 at the front, with 245/35 R19 tyres, and 11J x 19 at the rear, with 295/35 R19 tyres, with an offset of 44 or 50: the record permits both for the same wheel, and we choose neither. For winter, the rear wheel becomes a 10.5J x 19 with an offset of 55. koleso.ee gives the same wheels and the same front offset; at the rear, it gives 50 for the original fitment in 19 as in 20 inches, whereas the record gives 47 in 20 inches: the record prevails.

The load the wheel must carry

The engine is mid-mounted: the rear carries the most. The records give, depending on the version and the body style, a permissible load of 870 to 960 kg on the front axle and 1,100 to 1,195 kg on the rear axle, i.e. 435 to 480 kg per front wheel and 550 to 597.5 kg per rear wheel; the rear tyre keeps at least the load index of the original fitment, 103 for 305/30 R20 and 104 for 295/35 R19 (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 (4S)

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.
