The C190 AMG GT is a front-engined, rear-drive car with very high factory offsets and a large stagger, especially on the wide-body GT C and GT R. Owners mostly move to a 20-inch front and 21-inch rear for a fuller look, or fit wider rear tyres on the factory GT C and GT R wheels for track grip.

Read these before choosing wheels for the AMG GT: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
Owner-documented on a GT S lowered about 0.75 inch on adjustable springs, with no rubbing reported after alignment. A forged-wheel maker lists a near-identical 20x9.5 ET50 and 21x12 ET63 for the GT S. For a 10-inch front, owners suggest around ET54.
Forged-wheel fitment for the wide-body GT C on the road. The rear offset is close to the factory GT C rear (ET46), so the rear track barely changes. Confirm the brake package before ordering.
GT C owners run a 275/35 R19 front on the factory front wheel for a little more grip. A 345 rear is reported to need the GT R's 20x12 ET52 rear wheel to avoid arch contact over bumps, while 335/30 R20 fits the GT C's own ET46 rear wheel.
Check the exact setup
There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.
Measure before ordering
A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.
These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.
Upload a photo and start with a look that suits the AMG GT. Try the wheels, colour and stance before you spend on parts.

These tools start with the AMG GT, 19-inch front size. Choose your own trim or axle in the calculator if it differs.
5x112, with a 66.6 mm centre bore and M14x1.5 wheel bolts.

19x10 ET56 front with 275/35 R19 tyres and 20x12 ET52 rear with 325/30 R20 tyres.
Owners report 335/30 R20 fits the factory 12-inch GT C rear wheel. A 345/30 R20 needs the GT R's ET52 rear wheel to avoid rubbing.
The dealer catalogue approves the GT and GT S 19/20-inch set for those models only, not the GT C or GT R. The GT C uses a wider 12-inch rear wheel against the GT S's 11-inch rear.
Factory tyre (tire) sizes for the 2014–2021 Mercedes-AMG AMG GT C190 / R190 are 255/35 R19, 295/35 R19, 265/35 R19, 295/30 R20, 305/30 R20, 275/35 R19 and 325/30 R20, depending on trim, with wider rears on staggered setups. Your tyre placard shows the size for your car.

This guide is a starting point, not a fitment guarantee. Specs can differ by market, trim and previous modifications. Confirm all sizes, clearances and fastener requirements with a qualified wheel and tyre professional before buying or fitting parts.
