The 2022 Mercedes-Benz Trucks GLS580 sits in the modern luxury SUV class where power, weight, and upscale road manners all place real importance on getting tire fitment exactly right. On this vehicle, tire choice is tied closely to wheel diameter and axle position, with staggered front and rear radial sizes used across 21-inch, 22-inch, and 23-inch fitments. That makes the decision less about choosing between old and new construction and more about confirming the exact wheel setup, then selecting the right size for each end of the vehicle. Owners should also pay close attention to appearance, clearance, and any wheel or suspension changes before replacing tires.
Which Tire Size Is Right for The 2022 Mercedes-Benz Trucks GLS580
The 2022 Mercedes-Benz Trucks GLS580 uses six primary tire sizes, and the correct choice depends first on whether you are selecting a front or rear tire and which wheel diameter is on the vehicle. All of the primary fitments are radial, but the sizes vary across 21-inch, 22-inch, and 23-inch wheel packages, so confirming the exact wheel and axle position is the essential first step before comparing tire options.
The 275/45R21 size is a metric radial format, with 275 indicating section width in millimeters, 45 indicating the aspect ratio, and 21 identifying the wheel diameter in inches. On the 2022 Mercedes-Benz Trucks GLS580, this is a front tire size used with a 21-inch wheel. Its dimensions create a clear fitment relationship with the matching rear setup, so it should be chosen only when the vehicle is equipped for that specific front axle and wheel combination. Checking the actual wheel package on the SUV is more important than assuming all GLS580 models use the same front tire.
The 285/40R23 size is a metric radial, with a 285-millimeter section width, a 40-series profile, and a 23-inch rim diameter. On the 2022 Mercedes-Benz Trucks GLS580, it serves as a front fitment for vehicles using the larger 23-inch wheel package. This size works as part of a staggered setup, so it is meant to be matched with the corresponding rear tire rather than selected on its own. Owners replacing tires should confirm both wheel diameter and front-versus-rear position before moving forward with any 23-inch fitment.
The 285/45R22 code identifies a metric radial tire with a 285-millimeter section width, a 45-series sidewall profile, and a 22-inch wheel diameter. For the 2022 Mercedes-Benz Trucks GLS580, this is a front tire size used on the 22-inch wheel setup. Its role is tied to a staggered fitment, so the front tire must be selected in coordination with the correct rear counterpart on the same wheel package. This is the right size to evaluate only after confirming that the SUV carries the 22-inch front wheels rather than the 21-inch or 23-inch alternatives.
The 315/40R21 size is a metric radial format, with 315 showing section width in millimeters, 40 indicating aspect ratio, and 21 showing wheel diameter. On the 2022 Mercedes-Benz Trucks GLS580, this is the rear tire paired with the 21-inch front setup. Its wider section reflects the vehicle's staggered arrangement, where rear and front tires are intentionally different sizes. Buyers should treat this as a position-specific rear fitment and verify that the vehicle still has the correct 21-inch rear wheels and matching front size before selecting a replacement.
The 325/35R23 code describes a metric radial tire with a 325-millimeter section width, a 35-series profile, and a 23-inch rim diameter. On the 2022 Mercedes-Benz Trucks GLS580, it is the rear companion size for the 23-inch staggered wheel package. The extra width and low-profile format make wheel confirmation especially important, since this is not interchangeable with the rear sizes used on the 21-inch or 22-inch setups. Anyone replacing this tire should verify that the rear wheels remain 23 inches and that the matching front fitment is still in place.
The 325/40R22 size is a metric radial tire, with 325 as the nominal width in millimeters, 40 as the aspect ratio, and 22 as the wheel diameter in inches. For the 2022 Mercedes-Benz Trucks GLS580, this is the rear tire used with the 22-inch wheel package. It belongs to a staggered front-and-rear arrangement, so it should be considered as part of the complete 22-inch setup rather than as a universal GLS580 rear tire. Verifying wheel diameter and matching it to the correct front size is the key step before choosing a replacement.
Fitment on the 2022 Mercedes-Benz Trucks GLS580 is split by axle position rather than shared across a single all-around size. Checking whether you are replacing a front or rear tire matters just as much as confirming whether the vehicle has 21-inch, 22-inch, or 23-inch wheels.

2022 Mercedes-Benz Trucks GLS580 4Matic Front
The 2022 Mercedes-Benz Trucks GLS580 4Matic Front uses radial tire fitments that vary by wheel package, with separate front sizes for 21-inch, 22-inch, and 23-inch setups. That means the replacement decision starts with verifying the actual front wheel diameter before comparing the correct tire for that position.
The 2022 Mercedes-Benz Trucks GLS580 4Matic Rear uses wider radial tire sizes that correspond to the same 21-inch, 22-inch, and 23-inch wheel packages used at the front. Rear selection should be handled as part of a staggered fitment, with wheel diameter and the matching front setup confirmed before ordering replacements.
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
Owners of a 2022 Mercedes-Benz Trucks GLS580 usually need clarity on front-versus-rear sizing, wheel diameter, staggered radial fitment, and what to inspect before replacing tires on a modern luxury SUV.
Tire Size & Fitment
What tire size fits a 2022 Mercedes-Benz Trucks GLS580?
The 2022 Mercedes-Benz Trucks GLS580 uses a staggered radial tire setup with different front and rear sizes. Front sizes are 275/45R21, 285/45R22, and 285/40R23, while rear sizes are 315/40R21, 325/40R22, and 325/35R23.
The correct choice depends on two things: which axle you are replacing and which wheel diameter is on the vehicle. A GLS580 with 21-inch wheels uses a different front and rear pairing than one equipped with 22-inch or 23-inch wheels, so checking the actual wheel package before buying tires is essential.
What size rim does a 2022 Mercedes-Benz Trucks GLS580 use?
The 2022 Mercedes-Benz Trucks GLS580 uses 21-inch, 22-inch, or 23-inch rims, depending on the wheel package installed on the vehicle. Those rim diameters correspond directly to the tire sizes used at the front and rear, and all of the primary fitments are radial.
Rim diameter needs to be confirmed before anything else because the GLS580 does not use one universal wheel size. A front 275/45R21 and a rear 315/40R21 belong to one setup, while the 22-inch and 23-inch combinations use their own matching front and rear tires.
Why does the 2022 Mercedes-Benz Trucks GLS580 have more than one tire size?
The 2022 Mercedes-Benz Trucks GLS580 has more than one tire size because it uses staggered fitment and is offered with multiple wheel diameters. The front tires are narrower than the rear tires, and each wheel package has its own matched front and rear combination.
That means tire selection is not just a matter of knowing the model name. The owner needs to confirm whether the vehicle has 21-inch, 22-inch, or 23-inch wheels and whether the tire being replaced is on the front or rear axle before choosing the correct size.
Choosing the Right Tire
What should I consider when choosing a 2022 Mercedes-Benz Trucks GLS580 tire?
Start with the exact size, axle position, and wheel diameter already on the vehicle. The 2022 Mercedes-Benz Trucks GLS580 uses radial tires in staggered front and rear combinations, so the correct replacement depends on whether the SUV has 21-inch, 22-inch, or 23-inch wheels.
After confirming fitment, compare the replacement tire's intended use with how the GLS580 is driven. Owners should also verify that any previous wheel changes, tire substitutions, or suspension modifications have not altered the original front-to-rear setup, since this vehicle's fitment is closely tied to its wheel package.
How do I choose between the available front tire sizes for a 2022 Mercedes-Benz Trucks GLS580?
The front tire size is chosen by wheel diameter, not by preference alone. A 2022 Mercedes-Benz Trucks GLS580 front fitment is 275/45R21 with 21-inch wheels, 285/45R22 with 22-inch wheels, or 285/40R23 with 23-inch wheels.
That makes the decision fairly straightforward once the front wheel size is confirmed. It is also important to match the front tire to the corresponding rear size for the same package, since a staggered setup depends on the proper front-and-rear relationship rather than mixing unrelated sizes.
How do I choose between the available rear tire sizes for a 2022 Mercedes-Benz Trucks GLS580?
Rear tire choice on the 2022 Mercedes-Benz Trucks GLS580 depends on the wheel package installed. The rear sizes are 315/40R21 for the 21-inch setup, 325/40R22 for the 22-inch setup, and 325/35R23 for the 23-inch setup.
The key is to treat the rear tire as part of a matched staggered arrangement rather than as a stand-alone size. Confirm the wheel diameter stamped on the rear wheel and make sure the rear tire size still corresponds to the correct front fitment before replacing one tire or a full set.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Mercedes-Benz Trucks GLS580 restoration or cosmetic refresh?
Yes. Even on a newer luxury SUV like the 2022 Mercedes-Benz Trucks GLS580, correct tire fitment plays a major role in maintaining the intended stance and overall presentation. Because this vehicle uses staggered radial sizes, the visual balance depends on keeping the proper front and rear relationship.
A cosmetic refresh can be undermined quickly by the wrong wheel diameter or by mixing sizes from different setups. Owners trying to preserve a clean original-style appearance should confirm whether the GLS580 is on its 21-inch, 22-inch, or 23-inch package before selecting replacement tires.
How does tire sizing affect the appearance of a 2022 Mercedes-Benz Trucks GLS580?
Tire sizing has a visible effect on the 2022 Mercedes-Benz Trucks GLS580 because the SUV uses staggered widths and distinct profile differences across its 21-inch, 22-inch, and 23-inch fitments. Front and rear proportions are part of the vehicle's overall look, especially on larger wheel packages.
Using the wrong axle size or mixing tires from different wheel diameters can change that presentation quickly. Owners focused on appearance should verify the exact wheel setup already on the vehicle and keep the matched front-and-rear sizing relationship intact when replacing tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Mercedes-Benz Trucks GLS580?
Yes. Modifications can affect tire fitment on a 2022 Mercedes-Benz Trucks GLS580, especially because the vehicle uses staggered front and rear radial sizes across three different wheel diameters. Aftermarket wheels, suspension changes, or ride-height adjustments can alter clearance and change which tire dimensions work safely.
A GLS580 that no longer has its original wheel package should be checked carefully before ordering replacements by size alone. Measuring the installed wheels and confirming front and rear clearances during steering and suspension travel helps prevent buying tires that do not suit the modified setup.
What should I inspect before driving a 2022 Mercedes-Benz Trucks GLS580 on new tires?
Before driving a 2022 Mercedes-Benz Trucks GLS580 on new tires, inspect the wheel size, confirm the tires are mounted in the correct front or rear positions, and check inflation pressure. It is also wise to look over the wheels themselves for damage, bends, or issues that could affect bead seating.
A short road check should include watching for vibration, rubbing, or steering pull, especially on a staggered setup. Since this SUV may use 21-inch, 22-inch, or 23-inch wheels, even a small mounting mistake can put the wrong tire on the wrong axle and create immediate drivability issues.
What should I check before a longer drive in a 2022 Mercedes-Benz Trucks GLS580?
Before a longer drive, make sure the 2022 Mercedes-Benz Trucks GLS580 has the correct front and rear tire sizes for its wheel package, along with proper inflation and no signs of cuts, bulges, uneven wear, or air loss. A quick inspection of tread condition and valve stems is also worthwhile.
Longer trips place more importance on catching fitment or condition issues early. Since the GLS580 uses staggered radial sizing, owners should also verify that any recent rotation attempt, wheel swap, or tire replacement did not disturb the intended front-and-rear size pairing.
