The 2019 Mercedes-Benz AMG GT R sits at the sharp end of AMG's front-mid-engine performance lineup, blending supercar pace with track-focused chassis tuning and an unmistakably aggressive stance. On a car this specialized, tire fitment is part of the package rather than an afterthought. The 2019 Mercedes-Benz AMG GT R uses a staggered radial setup with 275/35R19 in front and 325/30R20 in the rear, so wheel position matters as much as size. Available choices center on modern blackwall performance radials from BFGoodrich and Nitto in the front size. The key is matching the correct front or rear fitment to the car's actual wheel setup and intended road use.
Which Tire Size Is Right for The 2019 Mercedes-Benz AMG GT R
The 2019 Mercedes-Benz AMG GT R uses two primary tire sizes, and they are tied to wheel position rather than interchangeable fitments. The front uses a 19-inch radial and the rear uses a 20-inch radial, so the first step is confirming whether you are replacing a front tire or a rear tire before comparing product options.
275/35R19 is a modern metric radial size where 275 identifies the nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. On the 2019 Mercedes-Benz AMG GT R, this is the front tire size, making steering response, wheel compatibility, and front-end clearance the key practical considerations. Available choices in this size include blackwall performance radials from BFGoodrich and Nitto across several g-Force and NT555 series offerings. This is the size to evaluate when replacing front tires and comparing performance-oriented product differences within the correct fitment envelope.
325/30R20 is a modern metric radial size where 325 is the nominal section width in millimeters, 30 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2019 Mercedes-Benz AMG GT R, this is the rear tire size, so it belongs only on the 20-inch rear wheel position rather than at all four corners. Its very wide, low-profile format reflects the car's staggered high-performance setup and makes exact wheel-position matching especially important. Choose this size only when replacing the rear tires and confirm that the car still has the proper rear wheel and suspension configuration.
Fitment on the 2019 Mercedes-Benz AMG GT R is straightforward once wheel position is identified, because the covered sub-models separate the car into front and rear tire applications. Checking the exact front or rear fitment matters here more than comparing trim variations.

2019 Mercedes-Benz AMG GT R Base Front
The Base Front application uses the 275/35R19 radial size on a 19-inch wheel position. Tire selection here centers on choosing the right front fitment among available blackwall performance radials and confirming compatibility with the existing wheel width and setup.
The Base Rear application uses the 325/30R20 radial size on a 20-inch wheel position. Rear replacement depends on matching the staggered setup correctly and verifying that the wheel, suspension, and overall vehicle configuration remain consistent with this extra-wide rear fitment.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2019 Mercedes-Benz AMG GT R?
The 2019 Mercedes-Benz AMG GT R uses a staggered radial tire setup with 275/35R19 in the front and 325/30R20 in the rear. Those are two different primary sizes, tied to two different wheel positions, so they are not a single all-around fitment.
That means the first step is identifying whether you are replacing a front tire or a rear tire. It is also important to confirm that the car still has its intended 19-inch front and 20-inch rear wheel arrangement, especially if aftermarket wheels or suspension changes have been made.
What size rim does a 2019 Mercedes-Benz AMG GT R use?
The 2019 Mercedes-Benz AMG GT R uses two rim diameters as part of its staggered setup: a 19-inch front rim for 275/35R19 tires and a 20-inch rear rim for 325/30R20 tires. The different diameters are part of the vehicle's front-to-rear tire fitment design.
Rim diameter should be confirmed before selecting a replacement tire, because a 19-inch front tire and a 20-inch rear tire are not interchangeable. Owners should also verify actual wheel width and overall wheel setup if the car has been modified or if the current wheels are not original to the vehicle.
Why does the 2019 Mercedes-Benz AMG GT R have more than one tire size?
The 2019 Mercedes-Benz AMG GT R has more than one tire size because it uses a staggered fitment, with one size for the front and a different size for the rear. The front position uses 275/35R19, while the rear uses a wider 325/30R20 tire.
For the buyer, that means tire selection starts with wheel position rather than simply matching the vehicle name. Replacing only one pair requires extra care to avoid ordering the wrong diameter or section width, and a full set should be matched to the car's intended front-and-rear layout.
Choosing the Right Tire
What should I consider when choosing a 275/35R19 tire for a 2019 Mercedes-Benz AMG GT R?
A 275/35R19 tire for the 2019 Mercedes-Benz AMG GT R should first match the front-wheel application, radial construction, and 19-inch rim diameter. From there, useful comparison points include tire series, rim-width compatibility, load specification where stated, and the kind of performance-oriented road use the car will see.
Available options in this front size include blackwall radials from BFGoodrich and Nitto, so the choice is less about changing fitment and more about selecting the right product within it. Checking the actual front wheel width before purchase helps narrow the field and avoids mismatching the tire to the wheel.
What sidewall styles are available for 2019 Mercedes-Benz AMG GT R tires?
The available 275/35R19 products for the 2019 Mercedes-Benz AMG GT R use a blackwall sidewall style. That keeps the appearance aligned with the contemporary, high-performance character of the car rather than introducing whitewall, redline, or other vintage-style sidewall treatments.
Sidewall style on this application is mostly an appearance and presentation decision within the proper size, but it still matters to owners who want the tire to suit the car's overall look. Since the available front choices stay within blackwall performance radials, the more meaningful product differences are series, specifications, and wheel compatibility.
What brands offer tires for the 2019 Mercedes-Benz AMG GT R?
BFGoodrich and Nitto offer tires in the available 275/35R19 front fitment for the 2019 Mercedes-Benz AMG GT R. Within that size, BFGoodrich options include several g-Force series offerings, while Nitto is represented by the NT555 G2.
Brand choice should be treated as one part of the selection process rather than the only factor. It still helps to compare each tire's series, rim-width range where stated, and other product characteristics so the front fitment matches the car's wheel setup and the owner's intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Mercedes-Benz AMG GT R?
A period-style approach on a 2019 Mercedes-Benz AMG GT R starts with keeping the staggered radial sizing intact: 275/35R19 in front and 325/30R20 in the rear. Because this is a modern high-performance car, preserving the intended wheel-position sizing matters more than trying to introduce a vintage-style construction or sidewall treatment.
Appearance choices are relatively straightforward in the available front products because the sidewall presentation stays blackwall and performance-oriented. Owners focused on originality-level detail should compare the tire's overall visual character to the car's factory-era look and verify that any replacement still suits the existing wheel setup.
Does correct tire fitment matter for a 2019 Mercedes-Benz AMG GT R restoration?
Correct tire fitment matters on a 2019 Mercedes-Benz AMG GT R because the car uses a staggered front-and-rear arrangement rather than a single universal size. Keeping the correct 275/35R19 front and 325/30R20 rear relationship preserves the intended stance and avoids turning a specialized fitment into a guesswork exercise.
On a restoration-minded or collector-kept example, fitment accuracy affects both presentation and mechanical compatibility. Even when the goal is mostly cosmetic freshness, wheel diameter, actual wheel width, and any prior modifications should be checked closely so the replacement tires remain consistent with the car's established setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mercedes-Benz AMG GT R?
Modifications can absolutely affect tire fitment on a 2019 Mercedes-Benz AMG GT R, especially because the car already uses a wide staggered setup with different front and rear diameters. Aftermarket wheels, altered wheel widths, suspension changes, or lowered ride height can all change how a tire sits and clears.
That makes it important to verify the actual wheel dimensions and inspect steering and fender clearance before choosing replacement tires. A car that still wears the intended front and rear wheel setup is easier to match correctly, while a modified example should be measured rather than assumed.
What should I inspect before driving a 2019 Mercedes-Benz AMG GT R on new tires?
Before driving a 2019 Mercedes-Benz AMG GT R on new tires, inspect inflation pressure, bead seating, visible sidewall condition, and overall clearance at both front and rear wheel positions. It also helps to confirm that the correct 275/35R19 fronts and 325/30R20 rears were installed in the proper locations.
A short visual check can prevent common problems such as position mix-ups, rubbing, or air loss after installation. On a high-performance car with staggered sizing, it is also wise to recheck wheel fastener torque, look for any contact marks after the first drive, and monitor pressures as the tires settle in.
What should I check before a longer drive in a 2019 Mercedes-Benz AMG GT R?
Before a longer drive in a 2019 Mercedes-Benz AMG GT R, check tire pressure, tread condition, age-related cracking, cuts, bulges, and any signs of slow air loss. The staggered setup also deserves a quick confirmation that the 19-inch front and 20-inch rear tires are still correctly matched to their wheel positions.
Longer trips put more heat and continuous load into the tires, so small issues are more likely to show up than on a short local drive. It is smart to inspect the inside shoulder areas as well, especially on a performance car, and to make sure no suspension or alignment issue is causing uneven wear.
