The 2020 Mercedes-Benz AMG GT sits firmly in the modern high-performance grand touring world, blending long-hood proportions with the kind of sharp chassis and power delivery that make tire choice a real part of the driving experience. On this car, fitment centers on staggered radial sizes, with different front and rear requirements and both 19-inch and 20-inch rear applications depending on setup. That makes the key decision less about finding any tire that fits and more about confirming the exact front or rear size, then comparing the available series and brand options within that size. Owners focused on road manners, appearance, and proper stance should verify wheel dimensions and the current vehicle setup before choosing.
Which Tire Size Is Right for The 2020 Mercedes-Benz AMG GT
The 2020 Mercedes-Benz AMG GT uses four primary tire sizes, and the right one depends first on whether you are selecting a front or rear tire and then on the wheel diameter already on the car. Front fitment stays on 19-inch rims, while rear fitment can use either a 19-inch or 20-inch size. Before comparing tire options, confirm the exact sub-model position and rear wheel diameter.
A 255/35R19 tire is a metric radial size with a 255-millimeter section width, a 35-series profile, and fitment for a 19-inch rim. On the 2020 Mercedes-Benz AMG GT, this is one of the front tire sizes and keeps the low-profile radial format expected on a modern performance car. Available choices in this size come from BFGoodrich, all in Blackwall form, with g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series options. This size should be matched to the front wheel setup and compared carefully against the current wheel width before selection.
A 265/35R19 tire uses the same modern metric radial format, but with a 265-millimeter section width, a 35-series profile, and a 19-inch rim diameter. For the 2020 Mercedes-Benz AMG GT, this is also a front fitment, so the practical question is confirming which front wheel setup the car actually carries. Product choices include BFGoodrich and Nitto offerings, all with Blackwall sidewalls, and the available series include g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Buyers choosing this size should verify the wheel dimensions already on the car rather than assuming all AMG GT front setups are the same.
A 295/30R19 tire is a wide modern metric radial with a 295-millimeter section width, a 30-series profile, and a 19-inch rim diameter. On the 2020 Mercedes-Benz AMG GT, this size belongs to the rear position and represents one of the staggered rear fitment options used on the model. Its role is different from the front sizes, so it should be selected only after confirming that the car is using a 19-inch rear wheel rather than the alternate 20-inch rear setup. That rear-wheel check matters before comparing any tire by brand, construction, or performance-oriented series.
A 295/30R20 tire keeps the same 295-millimeter section width and 30-series profile but moves to a 20-inch rim. For the 2020 Mercedes-Benz AMG GT, this is the alternate rear tire size, so it is tied directly to the rear wheel diameter on the car. It should not be confused with the 19-inch rear fitment, even though the section width and profile family look similar at a glance. This size is the correct starting point only when the AMG GT is already equipped with a 20-inch rear wheel and the rest of the rear setup supports that fitment.
Sub-model fitment on the 2020 Mercedes-Benz AMG GT is position-specific rather than one-size throughout the car. Front and rear tire selection must be separated, and the rear also requires confirmation of whether the car carries a 19-inch or 20-inch wheel.

2020 Mercedes-Benz AMG GT Base Front
The 2020 Mercedes-Benz AMG GT Base Front uses one of two 19-inch radial front tire sizes, so the wheel setup on the car matters before choosing between them. Once that is confirmed, tire selection becomes a comparison of available brand and series options within the correct front size.
The 2020 Mercedes-Benz AMG GT Base Rear uses a wide staggered rear fitment, with either a 19-inch or 20-inch radial tire depending on the rear wheel diameter. Rear tire selection should start with wheel confirmation, since a 295/30R19 and 295/30R20 are not interchangeable simply because they share the same section width.
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 2020 Mercedes-Benz AMG GT?
The 2020 Mercedes-Benz AMG GT uses staggered radial tire sizes rather than one size at all four corners. Front fitment uses either 255/35R19 or 265/35R19, while rear fitment uses either 295/30R19 or 295/30R20 depending on the wheel setup.
The first step is identifying whether you are replacing a front or rear tire, then confirming the actual wheel diameter on the car. That matters most at the rear, where both 19-inch and 20-inch applications exist, and it also helps avoid ordering a front size that does not match the current wheel and tire setup.
What size rim does a 2020 Mercedes-Benz AMG GT use?
A 2020 Mercedes-Benz AMG GT uses 19-inch rims at the front, and the rear fitment can use either a 19-inch or 20-inch rim depending on configuration. That is why the tire lineup includes two 19-inch front sizes, one 19-inch rear size, and one 20-inch rear size.
Wheel diameter should be confirmed before comparing tread designs or performance-oriented tire series. A tire marked for a 19-inch rim cannot be used on a 20-inch wheel, and rear applications need extra attention because the same 295 section width appears in both rear sizes with different rim diameters.
Why does the 2020 Mercedes-Benz AMG GT have more than one tire size?
The 2020 Mercedes-Benz AMG GT has more than one tire size because it uses a staggered layout with different dimensions front and rear, and the rear setup may be paired with either a 19-inch or 20-inch wheel. That creates separate fitment paths instead of one universal replacement size.
This means tire selection should start with the exact position on the car and the wheel already in place. Looking only at section width is not enough, especially at the rear, so checking the sidewall marking on the current tire and confirming wheel diameter will keep the replacement search pointed at the correct fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Mercedes-Benz AMG GT?
Start with the exact size and position on the car, since the 2020 Mercedes-Benz AMG GT uses staggered front and rear fitments and can have either a 19-inch or 20-inch rear wheel. After that, compare radial tire series, brand, wheel-width compatibility where stated, and any published load information within the correct size.
The better choice depends on how the car is used and how closely the replacement should match the current setup. A front tire should be chosen as part of the front pair, and a rear tire as part of the rear pair, with close attention to wheel dimensions so the selected tire suits the existing stance and clearance.
What sidewall styles are available for 2020 Mercedes-Benz AMG GT tires?
The available tire options for the 2020 Mercedes-Benz AMG GT in the listed front sizes use Blackwall sidewalls. That keeps the appearance clean and contemporary, which suits the AMG GT's modern grand touring and performance character without introducing whitewall, redline, or other vintage-style sidewall treatments.
Since the visible sidewall treatment stays consistent, the real comparison shifts to series design, brand, and the specific fitment details of the tire itself. Owners who want a matching appearance across an axle should still confirm that the replacement size and series align with the wheel setup already on the car.
What brands offer tires for the 2020 Mercedes-Benz AMG GT?
BFGoodrich and Nitto offer tire choices for the 2020 Mercedes-Benz AMG GT within the available product range shown here. BFGoodrich appears across multiple front-size options, while Nitto is available in the 265/35R19 front size through the NT555 G2 series.
Brand alone should not be the only deciding factor, because size, wheel compatibility, and the intended position on the car still come first. Once the correct front or rear fitment is confirmed, comparing the available series within that size gives a much clearer path than treating all AMG GT tires as interchangeable.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Mercedes-Benz AMG GT?
Yes, modifications can affect tire fitment on a 2020 Mercedes-Benz AMG GT even when the tire size looks correct on paper. Aftermarket wheels, changes in wheel width, altered offsets, suspension lowering, or body changes can all influence how a staggered front and rear setup sits and clears.
That makes it important to inspect the car as it actually sits rather than relying only on stock-size assumptions. Measuring the current wheel diameter and width, then checking inner clearance, outer fender room, and steering travel at the front, helps prevent conflicts that may not show up in the tire size alone.
What should I inspect before driving a 2020 Mercedes-Benz AMG GT on new tires?
Before driving a 2020 Mercedes-Benz AMG GT on new tires, inspect the wheel size, confirm that front and rear tires are mounted in the correct positions, and check air pressure, bead seating, and overall clearance. It is also smart to look for any rubbing points around the suspension, fender liners, and steering range.
A performance car with staggered sizing benefits from a careful once-over after installation, especially if wheel or suspension changes have been made at some point. Recheck pressure after the first drives, watch for uneven contact or vibration, and make sure the replacement tires match the intended front or rear application.
How often should tires on a 2020 Mercedes-Benz AMG GT be inspected?
Tires on a 2020 Mercedes-Benz AMG GT should be inspected regularly, not just when tread looks worn. A quick visual check for air loss, sidewall damage, punctures, uneven wear, and embedded debris is worthwhile before routine driving, and a closer inspection should be part of normal maintenance intervals.
Low-profile performance tires can show the effects of alignment changes, pothole impacts, or underinflation fairly quickly, so frequent inspection helps catch problems early. It also helps confirm that the front and rear tires are wearing as expected for a staggered setup and that no clearance issue is developing over time.
