Frequently asked questions: wheels for the Audi TT RS 8J

What are the original wheel offsets for an Audi TT RS 8J?

According to its Swiss vehicle type records, the same 9J wheel on all four corners, always with an offset of 52: in 18, 19 or 20 inches. [4, 11]

Which tyres, and which load index, for an Audi TT RS 8J?

245/40 R18 with a load index of 93, i.e. 650 kg per tyre; 255/35 R19 with an index of 96, i.e. 710 kg; 255/30 R20 with an index of 92, i.e. 630 kg; on all four corners. [4, 11, 14, 15]

What load per wheel for an Audi TT RS 8J?

The highest permissible load in its Swiss vehicle type records is 1,040 kg on the front axle and 870 kg on the rear axle, i.e. 520 and 435 kg per wheel. The 255/30 R20 tyre with a load index of 92 carries 630 kg. [13, 14, 15]

Which PCD, centre bore and bolts for an Audi TT RS 8J?

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]

Same fixing measurements

As original equipment, these cars have the same PCD, centre bore, thread and fixing as the Audi TT RS 8J: 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 TT RS 8J

  • Fitment worked out for your Audi TT RS 8J

Audi TT RS 8J: 5x112, a 57.1 mm hub, M14 x 1.5 bolts

The first-generation Audi TT RS (type 8J), coupé or roadster, as the 250 kW 2.5 TFSI and then the 265 kW TT RS plus, whose first Swiss vehicle type record dates from April 2009, 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 Only one of the sources read gives the tightening torque: we do not publish it.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 TT RS 8S that succeeds it has its own page.

18, 19 and 20 inches, on all four corners

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 the same 9J wheel on all four corners for the TT RS 8J, always with an offset of 52: in 18 inches with 245/40 R18 tyres, in 19 inches with 255/35 R19 tyres, in 20 inches with 255/30 R20 tyres. The width and offset do not change from one diameter to the next; only the tyre sidewall gets lower.

The load the wheel must carry

The highest permissible load in its records is 1,040 kg on the front axle and 870 kg on the rear axle, i.e. 520 and 435 kg per wheel. The tyre keeps at least the load index of the original fitment: 93 in 245/40 R18, 96 in 255/35 R19, 92 in 255/30 R20 (reading a tyre). Braking sets 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 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 TT RS (8J)

Our design office establishes your car's measurements from its exact version, stated on the registration certificate, and presents them to you before machining. Each set is cut from forged 6061-T6 aluminium, machined on a 5-axis CNC centre, in monoblock, two-piece or three-piece construction; 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.

Configure custom wheels for your Audi TT RS 8J: free 3D render, on request.
