Frequently asked questions: wheels for the Mercedes C 63 AMG W205

What are the original offsets for the wheels of a Mercedes-AMG C 63 W205?

A staggered fitment, according to its Swiss vehicle type records, which depends on the body style. The coupé and the convertible have 9J at the front with an offset of 25 and 10.5J at the rear with an offset of 57, in 18, in 19 or in 19 and 20 inches. The saloon and the estate have 8.5J at the front with an offset of 38 and 9.5J at the rear with an offset of 56, in 18 or in 19 inches. [3, 4, 12, 17]

Which tyres, and which load index, does a Mercedes-AMG C 63 W205 take?

Coupé and convertible: 255/40 R18 with a load index of 99 at the front, i.e. 775 kg per tyre, and 285/35 R18 with an index of 101 at the rear, i.e. 825 kg; 255/35 R19 with an index of 96, i.e. 710 kg, with 285/30 R19 with an index of 98, i.e. 750 kg, or 285/30 R20 with an index of 99. Saloon and estate: 245/40 R18 with an index of 97, i.e. 730 kg, and 265/40 R18 with an index of 101; 245/35 R19 with an index of 93, i.e. 650 kg, and 265/35 R19 with an index of 98. [4, 12, 19, 20]

What is the load per wheel on a Mercedes-AMG C 63 W205?

Its Swiss vehicle type records give the coupé a permissible load of 1,065 to 1,100 kg on the front axle and 1,055 to 1,125 kg on the rear axle, i.e. 532.5 to 550 kg per front wheel and 527.5 to 562.5 kg per rear wheel; the estate, 1,075 to 1,100 and 1,140 to 1,210 kg, i.e. 537.5 to 550 and 570 to 605 kg per wheel. The 245/35 R19 front tyre with a load index of 93 carries 650 kg. [3, 9, 13, 19, 20]

What PCD, centre bore and bolts does a Mercedes-AMG C 63 W205 use?

The PCD is 5x112, the centre bore 66.6 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: none 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 Mercedes C 63 AMG W205: PCD 5x112, centre bore 66.6 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 Mercedes C 63 AMG W205

  • Forged 6061-T6 aluminium
  • 5-axis CNC machining
  • Designed to JWL/VIA standards
  • Fitment worked out for your Mercedes C 63 AMG W205

Mercedes-AMG C 63 W205: 5x112, a 66.6 mm hub, M14 x 1.5 bolts

The Mercedes-AMG C 63 of the 205 series, as a saloon (W205), an estate (S205), a coupé (C205) and a convertible (A205), as the 350 kW C 63 and as the 375 kW C 63 S, is 5x112 on a 66.6 mm hub, with M14 x 1.5 wheel bolts: koleso.ee and SCC give these measurements, each cited in the table. None of the sources read gives its tightening torque: we do not publish it.

Two fitments, depending on the body style

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 C 63 that depends on the body style. The coupé and the convertible have 9J at the front at an offset of 25 and 10.5J at the rear at an offset of 57: in 18 inches, with 255/40 R18 and 285/35 R18 tyres; in 19 inches, with 255/35 R19 and 285/30 R19 tyres; or in 19 inches at the front and 20 inches at the rear, with 285/30 R20 tyres. The saloon and the estate have 8.5J at the front at an offset of 38 and 9.5J at the rear at an offset of 56, in 18 inches (245/40 R18 and 265/40 R18) or in 19 inches (245/35 R19 and 265/35 R19). A coupé wheel therefore does not carry over to a saloon: the width and the offset change on both axles.

The load the wheel must carry

The records give the coupé a permissible load of 1,065 to 1,100 kg on the front axle and 1,055 to 1,125 kg on the rear axle, i.e. 532.5 to 550 and 527.5 to 562.5 kg per wheel, and the estate 1,075 to 1,100 and 1,140 to 1,210 kg, i.e. 537.5 to 550 and 570 to 605 kg per wheel. The tyre keeps at least the load index of the original fitment, from 93 to 101 depending on the size (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 Mercedes-AMG C 63 (W205, S205, C205, A205)

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.
