The 2024 Mercedes-Benz AMG GT 63 blends modern grand touring capability with AMG performance, and its tire fitment reflects that balance of speed, grip, and chassis precision. This is not a one-size setup, but a staggered radial arrangement that varies by body style, axle position, and wheel diameter. The 2-door uses 21-inch front and rear sizes, while the 4-door spans 19-, 20-, and 21-inch combinations depending on configuration. That makes the first step identifying the exact front or rear position and the wheel diameter on the car. Once that is confirmed, tire selection becomes a matter of matching the proper metric radial size to the intended road use and wheel setup.
Which Tire Size Is Right for The 2024 Mercedes-Benz AMG GT 63
The 2024 Mercedes-Benz AMG GT 63 uses eight primary tire sizes, and they do not apply interchangeably across every configuration. Fitment changes by 2-door or 4-door layout, front or rear position, and 19-, 20-, or 21-inch wheel diameter. Before choosing a tire, confirm the exact sub-model and whether you are selecting for the front axle or the rear.
295/30R21 is a metric radial size with a 295-millimeter section width, a 30-series aspect ratio, and a 21-inch rim diameter. On the 2024 Mercedes-Benz AMG GT 63, this size is used as a front fitment on the 2-door 4Matic+ configuration, where the low-profile construction supports the car's staggered high-performance setup. Its sizing points to a wide tread footprint paired with a short sidewall. This is a position-specific fitment, so it should be matched to the correct axle and wheel diameter rather than treated as a general AMG GT 63 tire size.
305/30R21 is a metric radial size that combines a 305-millimeter section width, a 30-series profile, and a 21-inch wheel diameter. This size serves as the rear fitment for the 2024 Mercedes-Benz AMG GT 63 4Matic+ 2-door, completing the staggered arrangement with a wider rear tire than the front. The combination of width and short sidewall is typical of a performance-oriented rear application. Selecting this size means confirming that the car retains its proper rear wheel and that the tire is being chosen for the rear axle only.
255/45R19 is a metric radial size with a 255-millimeter section width, a 45-series aspect ratio, and a 19-inch rim diameter. On the 2024 Mercedes-Benz AMG GT 63, it appears as a front fitment for the 4-door 4Matic+ configuration, where it represents the 19-inch front setup. Compared with the lower-profile 20- and 21-inch alternatives used on the same body style, this size is tied specifically to the 19-inch wheel package. The key selection step is confirming that the front wheel on the car is 19 inches before moving forward.
265/40R20 is a metric radial size that uses a 265-millimeter section width, a 40-series profile, and a 20-inch rim diameter. This size is used on the front of the 2024 Mercedes-Benz AMG GT 63 4Matic+ 4-door when equipped with the 20-inch front wheel setup. It sits between the 19-inch and 21-inch front fitments used on that body style, so it is important not to confuse it with other front sizes that may also appear on the AMG GT 63 nameplate. Choose this size only after confirming the exact 4-door wheel package and front axle position.
275/35R21 is a metric radial size with a 275-millimeter section width, a 35-series aspect ratio, and a 21-inch rim diameter. For the 2024 Mercedes-Benz AMG GT 63 4Matic+ 4-door, it serves as the front fitment in the 21-inch setup, distinguishing it from the 19-inch and 20-inch front alternatives used on the same model line. The lower profile and larger rim diameter make wheel verification essential before purchase. This size should be evaluated as a specific 4-door front application, not as a universal front tire for every AMG GT 63.
285/40R19 is a metric radial size that combines a 285-millimeter section width, a 40-series profile, and a 19-inch wheel diameter. This is the rear companion size for the 2024 Mercedes-Benz AMG GT 63 4Matic+ 4-door when equipped with the 19-inch setup, paired with a narrower front tire on the same package. Its role is defined by the staggered front-to-rear relationship rather than by the model name alone. The practical decision is to confirm both rear axle placement and 19-inch wheel diameter before comparing tires in this size.
295/35R20 is a metric radial size with a 295-millimeter section width, a 35-series aspect ratio, and a 20-inch rim diameter. On the 2024 Mercedes-Benz AMG GT 63 4Matic+ 4-door, it is the rear fitment for the 20-inch setup, paired with a 265/40R20 front tire. Nitto offers this size in the NT555 G2 series with a Blackwall sidewall, giving buyers at least one clearly performance-oriented product choice in the correct fitment. This size should be chosen only after confirming the rear axle and the 20-inch wheel package on the vehicle.
315/30R21 is a metric radial size using a 315-millimeter section width, a 30-series profile, and a 21-inch rim diameter. It serves as the rear fitment for the 2024 Mercedes-Benz AMG GT 63 4Matic+ 4-door when equipped with the 21-inch wheel setup, making it the widest rear size used across this model's listed configurations. The combination points to a dedicated staggered rear application rather than a general-use fitment. That makes rear position, wheel diameter, and the car's actual wheel package the essential checks before selection.
Sub-model fitment on the 2024 Mercedes-Benz AMG GT 63 varies by body style, axle position, and wheel package rather than following one shared tire size. Checking the exact 2-door or 4-door configuration and then confirming front versus rear placement is the key step before choosing a tire.

The 2-door AMG GT 63 uses a dedicated front radial fitment that is separate from its rear tire size. That means the front tire should be selected as part of a staggered setup, with wheel diameter and axle position confirmed before comparing replacements.
The 2-door AMG GT 63 rear application uses its own radial tire size, wider than the corresponding front fitment. Tire selection here should focus on the correct rear position and preserving the intended staggered front-to-rear relationship on the car.
The 4-door AMG GT 63 front fitment varies across three radial sizes tied to 19-, 20-, and 21-inch wheel packages. Choosing correctly starts with confirming which front wheel diameter is actually on the car, since the sizes are not interchangeable across all 4-door setups.
The 4-door AMG GT 63 rear fitment also changes with wheel package, using three different radial sizes across 19-, 20-, and 21-inch combinations. The right choice depends on matching the rear axle position and wheel diameter so the staggered setup stays consistent with the front.
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 2024 Mercedes-Benz AMG GT 63?
The 2024 Mercedes-Benz AMG GT 63 uses several tire sizes rather than one universal fitment. The listed sizes are 295/30R21 and 305/30R21 for the 2-door 4Matic+ front and rear, and 255/45R19, 265/40R20, 275/35R21, 285/40R19, 295/35R20, and 315/30R21 across the 4-door 4Matic+ front and rear combinations.
The important point is that these sizes are tied to specific axle positions and wheel packages. A front size should not be treated as a rear replacement, and a 19-inch fitment should not be confused with a 20- or 21-inch setup. Checking the car's exact body style, front or rear position, and current wheel diameter is the right first step.
What size rim does a 2024 Mercedes-Benz AMG GT 63 use?
The 2024 Mercedes-Benz AMG GT 63 uses 19-inch, 20-inch, and 21-inch rim diameters depending on configuration. The 2-door 4Matic+ uses 21-inch front and rear fitments, while the 4-door 4Matic+ can be equipped with 19-inch, 20-inch, or 21-inch front and rear combinations matched to the tire sizes used on each axle.
Rim diameter is the first hard check because the tire must match the wheel exactly. A 295/35R20 fits a 20-inch wheel, while a 315/30R21 fits a 21-inch wheel, even though both are rear sizes for the AMG GT 63. Looking at the tire sidewall or measuring only the tread is not enough when multiple wheel diameters are possible.
Why does the 2024 Mercedes-Benz AMG GT 63 have more than one tire size?
The 2024 Mercedes-Benz AMG GT 63 has more than one tire size because fitment changes by body style, axle position, and wheel package. The 2-door 4Matic+ uses a 21-inch staggered setup, while the 4-door 4Matic+ uses different front and rear sizes across 19-, 20-, and 21-inch combinations.
That means the model name alone is not enough to choose a tire. A buyer needs to confirm whether the car is a 2-door or 4-door, then verify whether the tire is for the front or rear axle, and finally match the wheel diameter. Those checks prevent ordering a correct AMG GT 63 size for the wrong configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Mercedes-Benz AMG GT 63?
Start with the exact fitment: body style, front or rear position, and wheel diameter. The 2024 Mercedes-Benz AMG GT 63 uses multiple metric radial sizes, so the first job is matching the tire to the correct axle and wheel package rather than choosing by model name alone.
After that, compare the available tire's construction, size designation, intended use, and any product specifications that matter to your setup. For example, the available 295/35R20 product is a radial Nitto NT555 G2 with a Blackwall sidewall. If the car has been modified with different wheels or suspension changes, actual clearance and wheel compatibility should be verified before selection.
What sidewall styles are available for 2024 Mercedes-Benz AMG GT 63 tires?
The currently listed product choice for the 2024 Mercedes-Benz AMG GT 63 shows a Blackwall sidewall in the 295/35R20 size. That means at least one correct rear 4-door fitment is available with a clean modern performance appearance rather than a whitewall, stripe, or raised-letter presentation.
Sidewall style matters mostly for visual character once the correct size and wheel diameter are confirmed. On a late-model AMG application like this, the priority remains matching the front or rear position and maintaining the proper staggered setup. Appearance can then be considered within the correct fitment rather than allowed to drive the size decision.
What brands offer tires for the 2024 Mercedes-Benz AMG GT 63?
The currently listed AMG GT 63 product offering includes Nitto in the 295/35R20 size. That product is part of the Nitto NT555 G2 series and is built as a radial tire for the 20-inch rear fitment used on one 4-door 4Matic+ configuration.
Brand comparison only matters after the exact fitment has been confirmed, because the AMG GT 63 uses several different front and rear sizes. A brand that appears in one correct size should not be assumed to cover every wheel package on the car. Matching the tire to the axle position and wheel diameter comes before any brand preference.
Restoration & Appearance
Does correct tire fitment matter for a 2024 Mercedes-Benz AMG GT 63 restoration?
Yes, correct tire fitment still matters even on a modern performance car like the 2024 Mercedes-Benz AMG GT 63. The car uses a staggered radial setup with multiple front and rear size combinations, so the right tire is part of preserving the intended stance, wheel relationship, and overall presentation.
Appearance on this model comes from getting the fitment right first, especially the axle-specific widths and the proper 19-, 20-, or 21-inch wheel diameter. A mismatch can change the visual balance as well as the practical setup. For a detail-focused project, compare the existing wheel package carefully before replacing any tire by size alone.
How does tire construction affect the appearance of a restored 2024 Mercedes-Benz AMG GT 63?
Tire construction is straightforward on the 2024 Mercedes-Benz AMG GT 63 because the primary fitments are radial throughout. That keeps the appearance in line with the car's contemporary AMG design language, where short sidewalls and large-diameter wheels are part of the overall visual character.
The visible difference usually comes less from switching construction and more from choosing the exact correct size and sidewall treatment within that radial format. A Blackwall presentation is currently represented in the 295/35R20 offering. Keeping the proper front-to-rear stagger and the correct wheel diameter will do more for the finished look than chasing appearance cues from unrelated vehicles.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Mercedes-Benz AMG GT 63?
Yes, modifications can affect tire fitment on a 2024 Mercedes-Benz AMG GT 63. The car already uses a staggered setup with multiple wheel diameters, so changes such as aftermarket wheels, altered offsets, suspension lowering, or spacer use can change the clearance relationship at the fender, steering, and suspension points.
Even when the tire size matches one of the correct AMG GT 63 fitments, the actual vehicle setup still needs to be checked. A modified 4-door on different wheels may not behave like a stock 4-door with the same nominal size. Verifying wheel width, wheel diameter, and clearance at full steering and suspension movement helps avoid expensive mistakes.
What should I inspect before driving a 2024 Mercedes-Benz AMG GT 63 on new tires?
Before driving, inspect basic installation and condition items: correct front and rear placement, proper wheel diameter match, visible bead seating, inflation, and any signs of rubbing once the car is back on the ground. On a staggered car like the 2024 Mercedes-Benz AMG GT 63, it is especially important to confirm that each tire is on its intended axle.
A short, careful road check is worthwhile after installation. Watch for vibration, steering pull, contact noise, or any sign that the tire is too close to suspension or bodywork. It also helps to recheck pressure after the first drive and look over the sidewalls for cuts, bulges, or unusual scuffing that could point to a fitment problem.
How often should tires on a 2024 Mercedes-Benz AMG GT 63 be inspected?
Tires on a 2024 Mercedes-Benz AMG GT 63 should be inspected regularly, not just when wear becomes obvious. A quick visual check for air loss, cuts, bulges, sidewall damage, and uneven tread wear is smart before routine driving, especially because the car uses wide, low-profile front and rear sizes that can be sensitive to road damage.
A more careful inspection is a good idea before longer drives and after any impact with potholes or road debris. Looking at all four corners matters because front and rear sizes differ, so wear patterns may not match. Pressure should also be monitored consistently, since an underinflated low-profile tire can change both appearance and road behavior quickly.
