A Mercedes AMG GT C190 (2014–2023) uses a 5x112 PCD and a centre bore of 66.6 mm.
Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.
Centre bore: the wheel must have a centre bore of 66.6 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 66.6 mm.
Offset: the original is ET46 to ET68. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
Fixings: thread M14x1.5, tightened to 180 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 275/35R19, 295/35R19, 295/30R20, 305/30R20. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).
Generations of the Mercedes AMG GT
The Mercedes AMG GT C190 is the oldest generation in our database. Next generation: Mercedes AMG GT 4 portes X290 (from 2018) — same 5x112 bolt pattern and same centre bore: original wheels swap between the two generations; check offset and diameter.
The original specs vary with the year, trim or wheel size. Identify your version from the tyre size marked on the sidewall.

Vehicles with the same PCD and centre bore
Same 5x112 PCD and same 66.6 mm centre bore: wheels from these vehicles bolt on and centre on a Mercedes AMG GT C190 without rings. Offset, width, diameter and caliper clearance still need checking.
These vehicles also use 5x112 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 66.6 mm, and will not fit if it is smaller.
A Mercedes AMG GT C190 (2014–2023) has a PCD of 5x112: 5 studs or bolts spaced around a circle 112 mm in diameter.
Does a Mercedes AMG GT C190 need a hub centric ring?
The centre bore (hub diameter) of a Mercedes AMG GT C190 is 66.6 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.
What offset (ET) for a Mercedes AMG GT C190?
The recorded original offset is ET46 to ET68 depending on the version and wheel size. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.
What tightening torque for the wheels of a Mercedes AMG GT C190?
The specified tightening torque is 180 Nm for M14x1.5 fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.
Which vehicles have the same PCD as a Mercedes AMG GT C190?
With the same PCD (5x112) and the same centre bore (66.6 mm), these include: Mercedes AMG GT C192, Mercedes CLE C236, Mercedes CLE C236 AMG, Mercedes E-Classe W214. Offset, width and rim diameter still need checking for each vehicle.
