The 2024 Mercedes-Benz Trucks GLS63 AMG sits at the high-performance end of the full-size luxury SUV world, blending AMG power with the stance and road presence expected from a flagship utility vehicle. Tire selection on this model is centered on staggered front-and-rear radial fitments rather than a single all-around size, and the exact setup changes with the 21-inch base arrangement or the available 22-inch and 23-inch wheel options. That makes wheel diameter and position especially important, since front and rear sizes differ within each package. The right choice starts with confirming the exact wheel option, then matching the tire’s size, profile, and intended use to the vehicle as equipped.
Which Tire Size Is Right for The 2024 Mercedes-Benz Trucks GLS63 AMG
The 2024 Mercedes-Benz Trucks GLS63 AMG uses six primary tire sizes across three staggered wheel packages, so the first step is confirming both the wheel diameter and whether you are replacing a front or rear tire. This model appears with 21-inch, 22-inch, and 23-inch radial setups, and each package uses different front and rear sizes rather than one uniform fitment.
285/45R22 is a metric radial size with a 285-millimeter section width, a 45-series aspect ratio, and fitment for a 22-inch rim. On the 2024 Mercedes-Benz Trucks GLS63 AMG, it serves as the front tire in the 22-inch staggered setup, so it is meant to work with a wider rear companion size rather than as a four-corner application. Its dimensions place it in a modern performance-oriented SUV fitment range. Choosing this size starts with confirming that the vehicle has the 22-inch option and that the tire is being matched to the front axle position.
325/40R22 is a metric radial size with a 325-millimeter section width, a 40-series aspect ratio, and a 22-inch rim diameter. This is the rear tire used with the 22-inch staggered package on the 2024 Mercedes-Benz Trucks GLS63 AMG, giving the rear axle a substantially wider footprint than the front. The size is part of a matched front-and-rear arrangement, not a stand-alone substitute for the other positions on the vehicle. It should be selected only after confirming both the 22-inch wheel package and rear placement, since the corresponding front tire uses a different size.
285/40R23 is a metric radial tire size that combines a 285-millimeter section width with a 40-series profile on a 23-inch rim. On the 2024 Mercedes-Benz Trucks GLS63 AMG, it is the front fitment for the 23-inch staggered option, paired with a wider rear tire in the same wheel package. The lower-profile construction reflects the visual and fitment character of a large-diameter modern wheel setup. This size is the right starting point only when the SUV is equipped with the 23-inch option and the tire being replaced is on the front axle.
325/35R23 is a metric radial tire size with a 325-millimeter section width, a 35-series profile, and fitment for a 23-inch rim. It is the rear tire in the 23-inch staggered setup for the 2024 Mercedes-Benz Trucks GLS63 AMG, where it complements a narrower front size and completes that specific wheel package. Its short sidewall and broad section width make position accuracy especially important during replacement. This size should be evaluated as a rear-only fitment for vehicles already equipped with the 23-inch option, not as a general replacement across other wheel packages.
275/50R21 is a metric radial size with a 275-millimeter section width, a 50-series aspect ratio, and a 21-inch rim diameter. On the 2024 Mercedes-Benz Trucks GLS63 AMG, it is the front tire in the base staggered arrangement, where it works with a wider rear tire rather than an identical mate on the back. Compared with the larger optional wheel packages, this setup uses a slightly taller sidewall while remaining firmly within modern SUV radial fitment. It should be chosen only after confirming that the vehicle retains the 21-inch base wheel package and that the front position is being replaced.
315/45R21 is a metric radial tire size that uses a 315-millimeter section width, a 45-series profile, and a 21-inch rim. This size is the rear fitment for the base 21-inch staggered package on the 2024 Mercedes-Benz Trucks GLS63 AMG, paired with a narrower 275/50R21 front tire. Because it belongs to a front-and-rear staggered arrangement, replacing it correctly depends on matching both axle position and wheel diameter. It is the proper rear size for the 21-inch setup and should be checked against the actual wheel package on the vehicle before selection.
Fitment on the 2024 Mercedes-Benz Trucks GLS63 AMG varies by wheel package and by axle position, so identifying the exact setup matters before choosing tires. The base 21-inch arrangement and the optional 22-inch and 23-inch packages all use staggered front-and-rear radial sizes rather than a single universal fitment.

2024 Mercedes-Benz Trucks GLS63 AMG (22 Inch Option) Front
The 22 Inch Option Front uses a dedicated front radial size within the SUV’s staggered 22-inch package. Tire selection here means matching the front position correctly and keeping the replacement consistent with the rear companion size already used on that wheel setup.
2024 Mercedes-Benz Trucks GLS63 AMG (22 Inch Option) Rear
The 22 Inch Option Rear carries its own wider rear radial size, separate from the front tire in the same package. Choosing for this position starts with confirming the 22-inch wheel option and avoiding any mix-up with the narrower front fitment or other wheel diameters.
2024 Mercedes-Benz Trucks GLS63 AMG (23 Inch Option) Front
The 23 Inch Option Front uses a front-specific radial tire sized for the 23-inch staggered package. Replacement should focus on maintaining the correct front fitment within that package and confirming that the vehicle is not equipped with the 21-inch or 22-inch setup instead.
2024 Mercedes-Benz Trucks GLS63 AMG (23 Inch Option) Rear
The 23 Inch Option Rear uses a wider rear radial size that completes the 23-inch staggered arrangement. That makes exact position and wheel-diameter confirmation essential, especially on vehicles where appearance changes or prior tire replacements may obscure the original package.
The Base Front position uses the front tire size from the standard 21-inch staggered setup. Selecting a replacement here is mostly about confirming the base wheel package and preserving the intended front-to-rear relationship of the 21-inch arrangement.
The Base Rear position uses the wider rear tire from the 21-inch base staggered package. Tire choice for this position depends on matching the rear axle correctly and verifying that the SUV still carries its original 21-inch wheel setup rather than one of the larger optional packages.
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:

Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Questions about 2024 Mercedes-Benz Trucks GLS63 AMG tires usually come down to staggered sizing, front-versus-rear fitment, and confirming whether the vehicle has the 21-inch base setup or the 22-inch or 23-inch wheel option. The FAQs below focus on size meaning, wheel fitment, selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2024 Mercedes-Benz Trucks GLS63 AMG?
The 2024 Mercedes-Benz Trucks GLS63 AMG uses staggered radial tire sizes, and the exact fitment depends on the wheel package. The base 21-inch setup uses 275/50R21 front and 315/45R21 rear. The 22-inch option uses 285/45R22 front and 325/40R22 rear. The 23-inch option uses 285/40R23 front and 325/35R23 rear.
That means there is not one universal tire size for every 2024 Mercedes-Benz Trucks GLS63 AMG. Start by confirming the wheel diameter on the vehicle, then verify whether the tire being replaced is on the front or rear axle. On a staggered setup, using the wrong position-specific size can create fitment and balance issues even when the rim diameter seems close.
What size rim does a 2024 Mercedes-Benz Trucks GLS63 AMG use?
The 2024 Mercedes-Benz Trucks GLS63 AMG appears with 21-inch, 22-inch, or 23-inch rims, depending on the wheel package. The base setup uses 21-inch rims, the intermediate package uses 22-inch rims, and the largest option uses 23-inch rims. Each package keeps the same rim diameter front and rear, but the tire widths and profiles remain staggered by axle position.
Rim diameter is the first fitment detail to verify before choosing tires for this SUV. Once that is confirmed, the next step is matching the correct front or rear size for that wheel package. A quick visual check can be misleading on large modern wheels, so read the existing tire sidewall and confirm the actual wheel setup before replacement.
Why does the 2024 Mercedes-Benz Trucks GLS63 AMG have more than one tire size?
The 2024 Mercedes-Benz Trucks GLS63 AMG has more than one tire size because it uses staggered front-and-rear fitments and is offered with multiple wheel packages. Each package pairs a narrower front tire with a wider rear tire, and the dimensions change again when moving from the 21-inch base arrangement to the 22-inch or 23-inch options.
That makes identification more important than it would be on a vehicle with four identical tires. The correct replacement depends on both wheel diameter and axle position, not just the model name. Checking the existing sidewall size, the wheel itself, and whether the vehicle still has its original setup helps avoid ordering a front size for the rear or the wrong package entirely.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Mercedes-Benz Trucks GLS63 AMG?
Start with the exact wheel package and axle position, because the 2024 Mercedes-Benz Trucks GLS63 AMG uses staggered radial sizes in 21-inch, 22-inch, and 23-inch configurations. A front tire and rear tire are not interchangeable within the same package, and the larger wheel options use different aspect ratios than the base setup.
After confirming the correct size, compare the tire’s intended use with the way the SUV is driven. Daily road use, seasonal mileage, and whether the vehicle still wears its original wheels all matter. It also helps to inspect the companion tire on the same axle and verify that the replacement will match the wheel diameter and general setup already on the vehicle.
How do I choose between the available front and rear fitments for a 2024 Mercedes-Benz Trucks GLS63 AMG?
There is no choice between front and rear fitments on a single wheel package, because each position has its own required size. The real decision is identifying whether the SUV has the base 21-inch setup, the 22-inch option, or the 23-inch option, then selecting the correct size for the axle being serviced.
That approach keeps the staggered arrangement intact, which is central to how this model is equipped. A tire chosen only by brand name or by approximate dimensions can still be wrong if it is meant for the opposite axle or another wheel package. Matching the replacement to the vehicle’s actual configuration is the key first step in choosing correctly.
What rim-fitment details should I compare when choosing 2024 Mercedes-Benz Trucks GLS63 AMG tires?
Rim diameter is the most important rim-fitment detail on the 2024 Mercedes-Benz Trucks GLS63 AMG, since this model uses 21-inch, 22-inch, and 23-inch wheel packages. After that, confirm whether the tire is for the front or rear axle, because each package uses a different width and profile at each end of the vehicle.
Wheel width and any prior wheel changes also deserve attention, especially on a modern staggered AMG setup. A GLS63 that has been modified with aftermarket wheels may no longer match the original package exactly. Verifying the actual wheel dimensions and checking tire-to-suspension and tire-to-fender clearance helps keep the replacement aligned with the SUV’s current configuration.
Restoration & Appearance
Does correct tire fitment matter for the appearance of a 2024 Mercedes-Benz Trucks GLS63 AMG?
Yes. On a 2024 Mercedes-Benz Trucks GLS63 AMG, correct tire fitment has a major effect on the vehicle’s stance because the model uses staggered front-and-rear sizes and large-diameter wheels. The visual balance of the SUV changes noticeably if the wrong profile or axle-specific size is installed, even when the tire can be mounted on a similar rim diameter.
Appearance on this model is tied closely to keeping the intended wheel package intact. A 21-inch base setup presents differently from the 22-inch and 23-inch options, and each package has its own sidewall proportions. Preserving the proper size relationship front to rear is the simplest way to maintain the GLS63 AMG’s original visual character as equipped.
How does tire construction affect the appearance of a restored or carefully kept 2024 Mercedes-Benz Trucks GLS63 AMG?
Tire construction is straightforward on the 2024 Mercedes-Benz Trucks GLS63 AMG because all primary fitments here are radial. That keeps the appearance decision focused less on bias-ply versus radial and more on maintaining the correct modern metric size, profile, and staggered front-to-rear relationship for the wheel package on the vehicle.
For an owner preserving the SUV’s original look, the main concern is avoiding a substitute size that changes sidewall height or disrupts the proportion between front and rear tires. Large luxury-performance SUVs depend heavily on that visual balance. Checking the exact sidewall size already fitted to the vehicle is the best starting point before making any appearance-driven replacement decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Mercedes-Benz Trucks GLS63 AMG?
Yes. Modifications can affect tire fitment on a 2024 Mercedes-Benz Trucks GLS63 AMG, especially because the vehicle already uses wide staggered tires and multiple wheel-diameter packages. Aftermarket wheels, altered offsets, suspension changes, lowering, or body modifications can all change the space available for the tire at the fender, suspension, or steering components.
Even when the sidewall size matches one of the original package sizes, the actual fit can change if the wheel itself differs from stock. That is why a modified GLS63 AMG should be checked at full steering lock and through normal suspension travel before assuming the original package size will behave the same way on the vehicle’s current setup.
What should I inspect before driving a 2024 Mercedes-Benz Trucks GLS63 AMG on new tires?
Before driving, inspect the installed tire size on each axle, confirm inflation is set appropriately for the tire and vehicle use, and make sure each tire clears the fender liner and suspension hardware. It also helps to look at the valve stems, wheel condition, and the companion tire on the same axle so the setup remains consistent side to side.
A short initial road check is useful on a staggered SUV fitment like the 2024 Mercedes-Benz Trucks GLS63 AMG. Listen for rubbing, watch for vibration, and recheck pressure after the first miles if anything feels unusual. Large-diameter wheel packages leave less visual margin for error, so small fitment issues are easier to catch early than after extended driving.
What should I check before a longer drive in a 2024 Mercedes-Benz Trucks GLS63 AMG?
Before a longer drive, check tread condition, visible damage, and air pressure on all four tires, then confirm that the front and rear sizes are correctly placed for the wheel package on the vehicle. On a 2024 Mercedes-Benz Trucks GLS63 AMG, that means making sure the staggered setup has not been mixed up during rotation, replacement, or prior service.
Age and condition matter just as much as tread depth on a low-use performance SUV. Look for cracking, bulges, cuts, or repeated pressure loss, and inspect the inner sidewalls if access allows. A vehicle that spends long periods parked should also be checked for flat spotting and storage-related deterioration before being asked to cover higher-speed highway miles.
