The 2021 Mercedes-Benz Trucks Maybach GLS600 sits at the top of the modern ultra-luxury SUV market, blending full-size utility with the kind of ride isolation, presence, and finish expected from the Maybach name. On a vehicle like this, tire fitment is tied closely to both wheel diameter and front-to-rear stagger. The front uses either 285/45R22 or 285/40R23, while the rear uses either 325/40R22 or 325/35R23, all in radial construction. That makes the real decision less about broad sizing theory and more about confirming the exact wheel setup, preserving the intended staggered fitment, and choosing a tire that suits the vehicle's appearance and road use.
Which Tire Size Is Right for The 2021 Mercedes-Benz Trucks Maybach GLS600
The 2021 Mercedes-Benz Trucks Maybach GLS600 uses four primary tire sizes because fitment is staggered front to rear and also varies by wheel diameter. The first step is confirming whether the vehicle is on 22-inch or 23-inch wheels, then matching the correct front and rear sizes as a set so the Maybach GLS600 keeps its intended proportions and fitment balance.
285/40R23 is a metric radial size in which 285 identifies the nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 23 is the rim diameter in inches. On the 2021 Mercedes-Benz Trucks Maybach GLS600, this size serves the front position with the 23-inch wheel setup. Its low-profile format is part of the vehicle's staggered luxury-performance fitment rather than a universal size for every corner. Before choosing this size, confirm that the GLS600 still has the correct 23-inch front wheel arrangement and has not been changed to a different wheel package.
285/45R22 is a metric radial size with a 285-millimeter nominal section width, a 45-series profile, radial construction, and a 22-inch rim diameter. On this Maybach GLS600, it is used on the front with the 22-inch wheel package. Compared with the 23-inch front size, the overall role is the same: maintaining the correct front fitment within a staggered setup. This is the size to evaluate when the vehicle is equipped with 22-inch front wheels, and it should be selected only after confirming that the front and rear wheel diameters match the intended package.
325/35R23 is a wide metric radial size in which 325 indicates the nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 23 is the rim diameter. On the 2021 Mercedes-Benz Trucks Maybach GLS600, this is a rear-position size used with the 23-inch staggered setup. The extra width is part of the vehicle's rear tire arrangement and should not be treated as interchangeable with the front size. It makes sense to evaluate this size only after confirming the Maybach still carries the correct 23-inch rear wheel and matching front fitment.
325/40R22 is a metric radial tire with a 325-millimeter nominal section width, a 40-series profile, and a 22-inch rim diameter. This size is used at the rear of the 2021 Mercedes-Benz Trucks Maybach GLS600 when the vehicle is equipped with the 22-inch wheel package. Like the 23-inch rear size, it is part of a staggered front-to-rear fitment and should be considered as a rear application rather than a general replacement size. Choosing it starts with verifying the actual rear wheel diameter and making sure the corresponding front size is matched correctly.
Fitment on the 2021 Mercedes-Benz Trucks Maybach GLS600 is straightforward once the position on the vehicle is identified, because the front and rear use different sizes. Checking whether you are replacing a front or rear tire, and whether the vehicle has 22-inch or 23-inch wheels, is the key step before selecting a tire.

2021 Mercedes-Benz Trucks Maybach GLS600 4Matic Front
The front of the 2021 Mercedes-Benz Trucks Maybach GLS600 4Matic uses either a 22-inch or 23-inch radial tire size, depending on the wheel package installed. Tire selection at the front starts with confirming wheel diameter, then matching the front size correctly within the vehicle's staggered setup.
The rear of the 2021 Mercedes-Benz Trucks Maybach GLS600 4Matic uses a wider radial tire than the front, again depending on whether the vehicle has 22-inch or 23-inch wheels. That means rear tire choice should be handled as a separate fitment decision, with wheel diameter and correct staggered pairing checked first.
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.
Frequently Asked Questions
These FAQs focus on the staggered tire fitment used on the 2021 Mercedes-Benz Trucks Maybach GLS600, including front versus rear sizing, 22-inch and 23-inch wheel packages, radial construction, and the practical checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2021 Mercedes-Benz Trucks Maybach GLS600?
The 2021 Mercedes-Benz Trucks Maybach GLS600 uses a staggered radial tire setup rather than one size at all four corners. Front fitment is either 285/45R22 or 285/40R23, while rear fitment is either 325/40R22 or 325/35R23, depending on which wheel package is on the vehicle.
The key is matching both position and wheel diameter. A front tire size should stay on the front, a rear tire size should stay on the rear, and 22-inch and 23-inch fitments should not be mixed unless the vehicle has been deliberately reconfigured with a properly matched wheel and tire package.
What size rim does a 2021 Mercedes-Benz Trucks Maybach GLS600 use?
The 2021 Mercedes-Benz Trucks Maybach GLS600 uses either 22-inch or 23-inch rims. The 22-inch setup pairs 285/45R22 front and 325/40R22 rear, while the 23-inch setup pairs 285/40R23 front and 325/35R23 rear.
Wheel diameter should be confirmed before ordering tires, because the Maybach GLS600 uses different front and rear widths within each wheel package. Checking the wheel itself, the tire sidewall, and the existing front-to-rear pairing helps prevent buying a correct-looking size that belongs to the opposite axle or a different diameter package.
Why does the 2021 Mercedes-Benz Trucks Maybach GLS600 have more than one tire size?
This Maybach GLS600 has more than one tire size because it uses a staggered setup, with narrower tires in front and wider tires in the rear, and it was fitted with more than one wheel diameter package. That creates four primary sizes across the full vehicle fitment range.
For the owner, that means tire selection is not just about finding a size that looks close. Position on the vehicle matters, and so does wheel diameter. Before replacing a tire, verify whether you are working on the front or rear axle and confirm whether the SUV is equipped with 22-inch or 23-inch wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2021 Mercedes-Benz Trucks Maybach GLS600?
Start with the exact position and wheel diameter, because the 2021 Mercedes-Benz Trucks Maybach GLS600 uses staggered fitment. Front and rear sizes are different, and each axle changes again between the 22-inch and 23-inch wheel packages.
After confirming the correct size, compare the tire's intended use with how the vehicle is driven and maintained. Clearance, wheel condition, and any prior wheel changes matter on a large luxury SUV. Staying with the correct front-to-rear pairing helps preserve the vehicle's intended stance, balance, and overall fitment integrity.
How do I choose between the available front and rear tire sizes for a 2021 Mercedes-Benz Trucks Maybach GLS600?
The choice is determined by the wheel package already on the vehicle rather than by preference alone. A Maybach GLS600 with 22-inch wheels uses 285/45R22 in front and 325/40R22 in the rear, while a 23-inch setup uses 285/40R23 in front and 325/35R23 in the rear.
That means the practical selection step is confirming what is physically installed today. Look at the current tire sidewalls and verify the wheel diameter before replacing anything. If the SUV has had aftermarket wheel changes, treat the current setup carefully and make sure the front and rear sizes still form a proper staggered combination.
What rim-fitment details matter when choosing 2021 Mercedes-Benz Trucks Maybach GLS600 tires?
Rim diameter is the first fitment detail that matters, because this vehicle uses either 22-inch or 23-inch wheels. Just as important, the front and rear rims are matched to different tire widths, with a narrower front size and a wider rear size.
A tire can share the correct diameter and still be wrong for the axle if the width and stagger are not matched properly. Owners should verify actual wheel sizing, confirm that the front and rear wheels have not been swapped, and inspect for any non-original wheel package that could change clearance or fitment expectations.
Restoration & Appearance
Does correct tire fitment matter for a 2021 Mercedes-Benz Trucks Maybach GLS600?
Yes. On a 2021 Mercedes-Benz Trucks Maybach GLS600, correct tire fitment affects more than basic sizing because the vehicle uses a staggered arrangement tied to specific 22-inch or 23-inch wheel packages. Keeping the proper front and rear relationship helps preserve the SUV's intended visual balance and fitment.
Appearance on a modern luxury vehicle is closely tied to proportion, especially with large-diameter wheels and wide rear tires. A mismatched diameter, profile, or axle position can alter that presentation quickly. Owners focused on maintaining an authentic Maybach look should confirm the existing wheel package before selecting replacement tires.
How does tire sizing affect the appearance of a 2021 Mercedes-Benz Trucks Maybach GLS600?
Tire sizing has a strong effect on the Maybach GLS600 because its look depends on a deliberate staggered layout and large wheel diameter. The front uses a 285-width tire, while the rear uses a wider 325-width tire, creating the planted, upscale stance expected from this model.
Changing that relationship can alter how the SUV sits visually within the wheel openings. Even when the tire technically mounts on the wheel, the wrong profile or axle placement can upset the intended appearance. Matching the correct 22-inch or 23-inch front-and-rear set is the cleanest way to keep the original visual character intact.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Mercedes-Benz Trucks Maybach GLS600?
Yes. Wheel changes, suspension lowering, spacer use, and other modifications can affect tire fitment on a 2021 Mercedes-Benz Trucks Maybach GLS600. Because the vehicle already uses wide rear tires and a staggered layout, even small changes can influence clearance at the fenders, suspension, or steering components.
Owners should verify the actual wheel diameter, width, and offset before assuming the original tire sizes still apply unchanged. A modified setup may need extra clearance checks at full steering lock and through suspension travel. That is especially important when replacing only one axle or when a previous owner changed the wheels.
What should I inspect before driving a 2021 Mercedes-Benz Trucks Maybach GLS600 on new tires?
Before road use, inspect the wheel diameter and axle position to confirm the correct front and rear sizes were installed. Then check tire pressure, bead seating, visible sidewall condition, and clearance around the inner fender, suspension, and steering areas on the front axle.
A short, careful test drive helps confirm there is no rubbing, vibration, or pulling. After that, recheck pressures and look for any contact marks. On a large luxury SUV with staggered sizing, it is also worth confirming that all four tires match the intended 22-inch or 23-inch package rather than a mixed set.
How often should tires on a 2021 Mercedes-Benz Trucks Maybach GLS600 be inspected?
Tires on a 2021 Mercedes-Benz Trucks Maybach GLS600 should be inspected regularly, not just when tread looks worn. Pressure loss, sidewall damage, cuts, punctures, and uneven wear can develop before a problem becomes obvious, especially on large-diameter, low-profile radial tires.
A visual check before longer drives is a sensible routine, and periodic closer inspection is important even on vehicles that are driven less often. Pay attention to the wider rear tires as well as the fronts, since the staggered setup means each axle has a different role. Any sign of rubbing, cracking, bulging, or repeated air loss deserves prompt attention.
