Mercedes-AMG GT tire size
Original tire sizes for the Mercedes-AMG GT, model years 2016, 2017, 2018, 2019, 2020 and 2021. Trim levels and wheel packages change the size within the same year, so confirm on the door-jamb sticker before ordering.
Check before you order. The surest answer is the tires on the car right now: the size is molded into the sidewall. The placard inside the driver's door tells you what the factory fitted, which can differ from what a previous owner put on. Our guide on reading a tire size shows exactly where to look.

Which brand should you pick?
Mercedes-AMG does not stamp its own approval code on tires the way Porsche or BMW do. Any tire in the right size that meets or exceeds the load index and speed rating on your door placard is a legitimate replacement, so pick on wet braking, tread life and price. Our picks for each size are on the size pages below.
The drawing carries the sizes we list for this car, so you know what you are looking for. The placard on the car is still the final word, and it is the only place that gives the cold pressures: the number molded into the sidewall is the maximum the tire can hold, not what your car wants.
What those tires cost
Mercedes-AMG GT tires: common questions
What size tires does a Mercedes-AMG GT take?
The most common original size is 255/35R19. Other model years and trims use different sizes, so check the list on this page and confirm against the sticker inside your driver's door.
Can I fit a different size on my Mercedes-AMG GT?
You can, within limits: the overall diameter should stay within about 3 percent of the original, and the load index and speed rating must meet or exceed the door placard. Anything further changes your speedometer reading and can rub at full lock.
