The 2019 Mercedes-Benz AMG GT sits firmly in the modern grand-touring performance world, blending long-hood proportions with serious speed and a chassis that depends heavily on correct front-to-rear tire balance. Tire selection on this car is less about vintage-style construction and more about confirming the exact staggered setup, since front sizes include 255/35R19 and 265/35R19 while rear fitment can be 295/30R19 or 295/30R20. All primary fitments are radial, and the available choices center on modern performance-oriented blackwall tires from BFGoodrich and Nitto. The key is matching the exact wheel diameter and axle position before comparing series, load capability, and overall setup.
Which Tire Size Is Right for The 2019 Mercedes-Benz AMG GT
The 2019 Mercedes-Benz AMG GT uses four primary tire sizes, and the first step is confirming both wheel position and rim diameter before choosing a tire. Front fitment uses a 19-inch radial in either 255/35R19 or 265/35R19, while the rear uses a wider 295-section tire on either a 19-inch or 20-inch rim. Once that exact setup is confirmed, the real comparison becomes series, brand, and wheel compatibility within the correct size.
255/35R19 is a metric radial size that identifies a 255-millimeter section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2019 Mercedes-Benz AMG GT, this is one of the front fitment sizes, so it belongs in a staggered setup rather than as a universal four-corner size. Available choices in this size come from BFGoodrich in blackwall form across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size is worth confirming carefully if the car has its original front wheel diameter but may vary from one front-wheel configuration to another.
265/35R19 is a metric radial size with a 265-millimeter section width, 35-series aspect ratio, radial construction, and a 19-inch wheel diameter. On the 2019 Mercedes-Benz AMG GT, it serves as an alternative front tire size, making axle position and exact wheel setup especially important before selection. Blackwall options in this size include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and the Nitto NT555 G2. This size makes sense when your AMG GT is equipped for the wider of the two 19-inch front fitments and you want to compare brand and series character within that specification.
295/30R19 is a metric radial size that uses a 295-millimeter section width, a 30-series profile, radial construction, and a 19-inch rim diameter. On the 2019 Mercedes-Benz AMG GT, this size belongs at the rear and reflects the car's staggered high-performance tire layout. Rear tire selection in this size should focus on matching the existing 19-inch rear wheels and maintaining the intended front-to-rear balance of the setup. This is the size to evaluate when the car carries 19-inch rear rims rather than the larger 20-inch rear configuration.
295/30R20 is a metric radial size with a 295-millimeter section width, 30-series profile, radial construction, and a 20-inch wheel diameter. On the 2019 Mercedes-Benz AMG GT, it is the larger rear fitment option, so it should be chosen only when the car is equipped with 20-inch rear wheels. The section width matches the 295/30R19 rear tire, but the rim diameter changes the fitment decision immediately. This size is the correct place to start when the rear of the car carries a 20-inch wheel and the goal is preserving the intended staggered arrangement.
Sub-model fitment on the 2019 Mercedes-Benz AMG GT is really a front-versus-rear fitment question, and the tire sizes are not interchangeable across the car. Checking the exact wheel position matters first, especially because the rear fitment can use either a 19-inch or 20-inch rim.

2019 Mercedes-Benz AMG GT Base Front
The 2019 Mercedes-Benz AMG GT Base Front uses a 19-inch radial front tire, with fitment appearing in either 255/35R19 or 265/35R19. That makes front-wheel width and the exact existing setup important before comparing BFGoodrich and Nitto choices within the correct size.
The 2019 Mercedes-Benz AMG GT Base Rear uses a wider 295/30 rear tire, but it may be mounted on either a 19-inch or 20-inch rim depending on the setup. Rear tire selection starts with confirming wheel diameter, since both sizes share the same width and profile family but not the same rim size.
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.
Best 2019 Mercedes-Benz AMG GT Tires for Sale
Available AMG GT tire choices center on modern radial blackwall performance tires in the front fitment sizes, with BFGoodrich and Nitto represented across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. The most useful comparisons are brand, series, load capability where stated, and rim-width compatibility.
Owners of a 2019 Mercedes-Benz AMG GT usually need to confirm the exact front and rear tire sizes first, then compare radial tire choices by wheel position, rim diameter, brand, and performance-oriented series. These FAQs focus on staggered fitment, product selection, wheel changes, and road-use checks.
Tire Size & Fitment
What tire size fits a 2019 Mercedes-Benz AMG GT?
The 2019 Mercedes-Benz AMG GT uses a staggered radial tire setup rather than one universal size. Front fitment is 255/35R19 or 265/35R19, while rear fitment is 295/30R19 or 295/30R20. That means tire size depends on wheel position and, at the rear, on rim diameter as well.
The most important next step is checking the exact wheels currently on the car. A front tire should not be chosen from the rear sizes, and a 19-inch rear tire cannot be mounted on a 20-inch rear wheel. Confirm the axle position, wheel diameter, and current size marking before comparing brands or tire series.
What size rim does a 2019 Mercedes-Benz AMG GT use?
The 2019 Mercedes-Benz AMG GT uses 19-inch and 20-inch rim diameters across its tire fitments. Both front tire sizes use a 19-inch rim, while the rear fitment can be either 19 inches with 295/30R19 or 20 inches with 295/30R20. Rim diameter is one of the main fitment variables on this car.
That makes wheel confirmation essential before replacing any tire. Reading the tire sidewall or measuring the existing wheel can prevent ordering the right width in the wrong diameter. On a staggered performance car like the AMG GT, the front and rear wheels should always be verified separately instead of assuming the whole car uses one rim size.
Why does the 2019 Mercedes-Benz AMG GT have more than one tire size?
More than one tire size appears on the 2019 Mercedes-Benz AMG GT because the car uses a staggered layout and not all wheel positions share the same specification. Front fitment uses either 255/35R19 or 265/35R19, while the rear uses a wider 295-section tire in either 19-inch or 20-inch form.
In practice, that means the correct choice depends on where the tire is being installed and which wheels are on the car now. The front and rear sizes serve different roles, so they should not be mixed casually. Any owner working with replacement wheels or a changed setup should verify current wheel dimensions before selecting tires.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 or 265/35R19 tire for a 2019 Mercedes-Benz AMG GT?
The first consideration is making sure the front of the 2019 Mercedes-Benz AMG GT actually uses 255/35R19 or 265/35R19, since both sizes appear in front fitment. After confirming that, compare the available radial options by tire series, brand, blackwall presentation, and any stated rim-width or load details that apply to the exact product.
Selection should also reflect how the car is used and whether the wheel setup is original or changed. A front tire chosen for the wrong width or wrong wheel specification can upset the intended balance of a staggered setup. Matching the exact size marking already in service is usually the most reliable starting point.
What brands offer tires for the 2019 Mercedes-Benz AMG GT?
BFGoodrich and Nitto both appear in the available tire choices for the 2019 Mercedes-Benz AMG GT. BFGoodrich is offered in several front-fitment series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, while Nitto appears in 265/35R19 with the NT555 G2 series.
Brand alone should not decide the tire. The more useful comparison is whether the tire is offered in the exact size needed for the front or rear axle, along with its series character and any wheel-fit details. On a staggered car, the correct size and position matter more than choosing a name first.
What tire series are available for the 2019 Mercedes-Benz AMG GT?
The available front-fitment tire series for the 2019 Mercedes-Benz AMG GT include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. These are all radial blackwall options, but they differ by series family and certain product-level details such as weight, rim-width guidance, and load information where stated.
Series choice matters most after the correct size is settled. A buyer comparing 255/35R19 to 265/35R19 still has a fitment question to answer first, while someone already confirmed on one front size can narrow the choice by series features. Keeping the axle position and wheel size straight will make those series comparisons much more useful.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mercedes-Benz AMG GT?
Yes, modifications can affect tire fitment on a 2019 Mercedes-Benz AMG GT, especially because the car already uses a staggered setup and more than one rear rim diameter. Aftermarket wheels, altered offsets, suspension changes, or lowering can all change how a 255/35R19, 265/35R19, 295/30R19, or 295/30R20 tire sits in the wheelhouse.
Any car that has been changed from stock should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension movement before tire replacement. That is particularly important at the rear, where 19-inch and 20-inch fitments both exist. Matching the sidewall size alone is not enough on a modified setup.
What should I inspect before driving a 2019 Mercedes-Benz AMG GT on new tires?
Before road use, inspect tire pressure, sidewall condition, bead seating, tread surface, and the basic match between the tire size and the wheel position on the 2019 Mercedes-Benz AMG GT. The front and rear sizes are different, so a quick confirmation that each tire is mounted on the correct axle is part of the inspection.
It also helps to look for any signs of rubbing, uneven spacing, or contact around the suspension and fender areas once the car is back on the ground. A short, careful test drive can reveal vibration or clearance issues early. On a performance-oriented car, small setup mistakes are easier to catch before regular driving begins.
What should I check before a longer drive in a 2019 Mercedes-Benz AMG GT?
A longer drive in a 2019 Mercedes-Benz AMG GT calls for a close look at tire pressure, visible damage, tread condition, and any signs of slow air loss. It is also smart to confirm that the staggered fitment is still consistent front to rear, with the correct 19-inch front tires and the correct 19-inch or 20-inch rear tires.
Collector cars and low-mileage performance cars can sit long enough for age and flat-spot concerns to matter, even when tread looks good. A buyer or owner should also watch for cracking, bulges, and vibration once underway. Checking those basics before a trip is a simple way to catch fitment or condition problems early.
