Frequently asked questions: wheels for the Mercedes A 45 AMG W176

What are the original offsets for the wheels of a Mercedes-AMG A 45 W176?

According to its Swiss vehicle type records, the same wheel on all four corners: 8J x 18 or 8J x 19, always with an offset of 48, and only as AMG alloy wheels. [3, 7]

Which tyres, and which load index, does a Mercedes-AMG A 45 W176 take?

235/40 R18 with a load index of 95, i.e. 690 kg per tyre, or 235/35 R19 with an index of 91, i.e. 615 kg, on all four wheels. [3, 7, 10, 11]

What is the load per wheel on a Mercedes-AMG A 45 W176?

Its Swiss vehicle type records give a permissible load of 1,115 kg on the front axle and 915 kg on the rear axle, i.e. 557.5 and 457.5 kg per wheel: the engine is at the front. The 235/35 R19 tyre with a load index of 91 carries 615 kg. [3, 7, 10, 11]

What PCD, centre bore and bolts does a Mercedes-AMG A 45 W176 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 A 45 AMG W176: 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 A 45 AMG W176

  • Forged 6061-T6 aluminium
  • 5-axis CNC machining
  • Designed to JWL/VIA standards
  • Fitment worked out for your Mercedes A 45 AMG W176

Mercedes-AMG A 45 W176: 5x112, a 66.6 mm hub, M14 x 1.5 bolts

The Mercedes-AMG A 45 4MATIC of the 176 series, with 265 kW and then 280 kW, whose first Swiss vehicle type records date from February 2013, 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 None of the sources read gives the tightening torque: we do not publish it. The A 45 W177 that succeeds it has its own page.

18 or 19 inches, a single 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 the same wheel on all four corners for the A 45: 8J x 18 with 235/40 R18 tyres, or 8J x 19 with 235/35 R19 tyres, always at an offset of 48. The records specify that these fitments apply to AMG alloy wheels only. The move from 265 to 280 kW, in 2015, changes none of these measurements.

The load the wheel must carry

The engine and the gearbox are at the front: the front carries the most. The records give a permissible load of 1,115 kg on the front axle and 915 kg on the rear axle, i.e. 557.5 and 457.5 kg per wheel. The tyre keeps at least the load index of the original fitment, 95 for 235/40 R18 and 91 for 235/35 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 Mercedes-AMG A 45 (W176)

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.
