The 2020 Mercedes-Benz Trucks GLE580 sits in the modern luxury SUV category where power, weight, and road manners all place real importance on getting tire fitment right. This is a sophisticated all-wheel-drive platform, and tire choice affects not just appearance but also ride balance and proper front-to-rear setup. The 2020 Mercedes-Benz Trucks GLE580 uses radial tire fitments that span 19-inch through 22-inch rim diameters, with both square and staggered sizing depending on configuration. That means the key decision is confirming exactly which wheel and axle setup the vehicle has before comparing tire sizes. Once that is settled, the focus shifts to maintaining the intended proportions, wheel compatibility, and clearance.
Which Tire Size Is Right for The 2020 Mercedes-Benz Trucks GLE580
The 2020 Mercedes-Benz Trucks GLE580 uses six primary tire sizes, and the correct one depends on whether the vehicle is running a 19-inch or 20-inch square setup or a 21-inch or 22-inch staggered front-and-rear arrangement. Before choosing a tire, confirm the exact sub-model position and wheel diameter, because front and rear sizes are different on the larger wheel combinations.
255/50R19 is a metric radial size in which 255 identifies nominal section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 19 is the rim diameter in inches. On the 2020 Mercedes-Benz Trucks GLE580, this size belongs to a square-fitment configuration rather than a staggered front-and-rear package. Its dimensions give it a distinct role within the model's fitment range, so it should be matched to the correct wheel setup. Buyers considering this size should confirm that all four wheels on the vehicle are meant to use the same 19-inch tire before selection.
275/50R20 is a metric radial size with a 275-millimeter nominal section width, a 50-series aspect ratio, and a 20-inch rim diameter. This is another square-fitment size for the 2020 Mercedes-Benz Trucks GLE580, used where the same tire size is carried at all four corners instead of a staggered arrangement. It differs meaningfully from the 19-inch option in wheel diameter and overall tire dimensions, so it should not be chosen by appearance alone. Confirming the vehicle's actual 20-inch wheel package is the first step before comparing tread design, load capability, and intended use.
275/45R21 is a metric radial size with a 275-millimeter nominal section width, a 45-series profile, and a 21-inch rim diameter. On the 2020 Mercedes-Benz Trucks GLE580, this size serves the front position in a staggered setup, where the rear tire is wider than the front. That front-specific role matters because the tire is part of a matched axle relationship rather than a four-corner square fitment. Choosing this size starts with confirming that the vehicle is equipped with the 21-inch staggered package and that the front wheels match the required diameter and width.
285/40R22 is a metric radial size that combines a 285-millimeter nominal section width, a 40-series profile, and a 22-inch rim diameter. On the 2020 Mercedes-Benz Trucks GLE580, it is the front tire size for the larger 22-inch staggered arrangement, paired with a wider rear tire. That means it should be treated as a front-axle fitment rather than a universal size for every wheel position on the vehicle. Buyers selecting this size should verify the 22-inch front wheel package first, then compare tire details with attention to maintaining the intended staggered setup.
315/40R21 is a metric radial size in which 315 indicates a notably wider nominal section width, 40 is the aspect ratio, and 21 is the rim diameter in inches. This size is used at the rear of a staggered 21-inch setup on the 2020 Mercedes-Benz Trucks GLE580, complementing the narrower 275/45R21 front tire. Its role is tied to rear-axle fitment, so it should not be selected as though it were part of a square four-tire package. The practical step is confirming that the vehicle's rear wheels are the correct 21-inch specification before moving on to tire choice.
325/35R22 is a metric radial size with a 325-millimeter nominal section width, a 35-series profile, and a 22-inch rim diameter. On the 2020 Mercedes-Benz Trucks GLE580, it is the rear component of the 22-inch staggered setup, working with the narrower 285/40R22 front tire. That front-to-rear relationship is the main reason this size needs to be matched carefully to the vehicle's existing wheel arrangement. Anyone evaluating this size should verify rear wheel diameter and the full staggered package before comparing tire options for appearance, use, or replacement planning.
Fitment on the 2020 Mercedes-Benz Trucks GLE580 varies by sub-model position and wheel package rather than following one universal size across every configuration. Checking the exact setup matters because some versions use the same size at all four corners, while others use staggered front-and-rear combinations.

2020 Mercedes-Benz Trucks GLE580 4Matic
The 2020 Mercedes-Benz Trucks GLE580 4Matic uses a square tire setup, with either a 19-inch or 20-inch radial size carried across the vehicle. That makes wheel-diameter confirmation the main step before selection, followed by choosing the tire characteristics that suit how the SUV is driven and maintained.
The 2020 Mercedes-Benz Trucks GLE580 4Matic Front uses the narrower front tire sizes within the staggered 21-inch and 22-inch packages. Tire selection here should preserve the intended front-axle sizing relationship and begin with confirming which staggered wheel package is on the vehicle.
The 2020 Mercedes-Benz Trucks GLE580 4Matic Rear uses the wider rear tire sizes that pair with the staggered 21-inch and 22-inch front fitments. That makes it important to match the rear size to the existing wheel package rather than treating it as interchangeable with the front tire.
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 2020 Mercedes-Benz Trucks GLE580 usually need clarity on exact tire size, rim diameter, staggered front-and-rear fitment, and how to choose the right radial tire once the wheel package is confirmed.
Tire Size & Fitment
What tire size fits a 2020 Mercedes-Benz Trucks GLE580?
The 2020 Mercedes-Benz Trucks GLE580 uses several radial tire sizes: 255/50R19, 275/50R20, 275/45R21, 285/40R22, 315/40R21, and 325/35R22. The correct size depends on whether the vehicle has a square setup with the same size at all four corners or a staggered setup with different front and rear tires.
The practical first step is checking the actual wheel package on the vehicle. A 19-inch or 20-inch setup uses one size front and rear, while the 21-inch and 22-inch packages split front and rear sizes. Matching the tire to the existing wheel diameter and axle position matters more here than choosing by appearance alone.
What size rim does a 2020 Mercedes-Benz Trucks GLE580 use?
The 2020 Mercedes-Benz Trucks GLE580 uses 19-inch, 20-inch, 21-inch, and 22-inch rim diameters depending on configuration. Those rim diameters correspond directly to the tire sizes used on the vehicle, and they are not interchangeable without confirming the full wheel and tire setup.
Rim diameter should be verified before anything else because it immediately narrows the correct tire choices. Once the wheel diameter is confirmed, the next step is checking whether the vehicle uses a square arrangement or a staggered front-and-rear layout. That avoids ordering a correct size for the wrong wheel position.
Why does the 2020 Mercedes-Benz Trucks GLE580 have more than one tire size?
The 2020 Mercedes-Benz Trucks GLE580 has more than one tire size because it was fitted with different wheel packages, including square 19-inch and 20-inch arrangements and staggered 21-inch and 22-inch combinations. In the staggered versions, the front and rear tires are intentionally different sizes.
That means the right choice depends on the exact wheel setup already on the SUV. Tire replacement should start with checking the sidewall on the current tires or confirming the wheel diameter and axle position. On a staggered setup, front and rear fitment need to stay coordinated rather than being selected as four identical tires.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Mercedes-Benz Trucks GLE580?
Start with the exact tire size and wheel diameter already on the 2020 Mercedes-Benz Trucks GLE580. This model uses multiple radial sizes, and some configurations are square while others are staggered, so the first decision is always matching the tire to the correct wheel package and axle position.
After size is confirmed, compare the tire's intended use, construction details, and any load-related specifications that apply to the replacement being considered. It also helps to think about how the vehicle is driven, whether all four tires need to match, and whether the suspension or wheels have been changed from the original setup.
How do I choose between the available tire sizes for a 2020 Mercedes-Benz Trucks GLE580?
Choosing between the available sizes is not a matter of preference alone, because each size belongs to a specific wheel package on the 2020 Mercedes-Benz Trucks GLE580. The 19-inch and 20-inch options are square setups, while the 21-inch and 22-inch options are split between narrower front and wider rear sizes.
That means the vehicle's existing wheels decide the starting point. Check the current sidewall markings, verify wheel diameter, and confirm whether the front and rear wheels are the same width or part of a staggered arrangement. Once that is established, replacement becomes a matter of selecting the right tire within the proper size rather than choosing among unrelated sizes.
What rim-width specifications should I compare when choosing 2020 Mercedes-Benz Trucks GLE580 tires?
Rim width matters because a tire must suit not only the correct diameter but also the wheel's width and intended position on the vehicle. On a 2020 Mercedes-Benz Trucks GLE580, that is especially important on staggered 21-inch and 22-inch packages, where the rear tire is wider than the front.
Check the actual wheel width stamped on the wheel or confirm it through the vehicle's wheel specifications before selecting a replacement. That simple step helps prevent choosing a tire that matches the diameter but does not suit the wheel correctly. It is also a useful checkpoint if the SUV has aftermarket wheels instead of its original package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Mercedes-Benz Trucks GLE580?
Yes. Wheel changes, altered offsets, suspension lowering, and other modifications can affect tire fitment on a 2020 Mercedes-Benz Trucks GLE580 even when the tire size itself looks correct. That matters most on staggered setups, where front and rear sizing already has less room for casual substitution.
A modified vehicle should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before replacement tires are chosen. Even a correct sidewall size can create problems if the wheel specification or ride height has changed. Verifying the actual setup on the vehicle is the safest way to avoid fitment surprises.
What should I inspect before driving a 2020 Mercedes-Benz Trucks GLE580 on new tires?
Before road use, inspect inflation pressure, wheel condition, lug torque, visible tread and sidewall condition, and the tire's seating on the rim. On a 2020 Mercedes-Benz Trucks GLE580, it is also wise to confirm that each tire is mounted in the correct front or rear position when the vehicle uses a staggered setup.
A short clearance check can prevent problems after installation. Turn the steering from lock to lock, look for any sign of rubbing, and recheck pressure after the first drives. Vehicles that see mixed daily and highway use benefit from early inspection because any mismatch in size or position usually reveals itself quickly.
How often should tires on a 2020 Mercedes-Benz Trucks GLE580 be inspected?
Tires on a 2020 Mercedes-Benz Trucks GLE580 should be inspected regularly, not just when tread appears worn. A quick check for pressure loss, uneven wear, cuts, bulges, and sidewall damage is worthwhile throughout the year, especially on an SUV that may see varying road conditions and heavier loads than a passenger car.
Frequent inspection is even more helpful when the vehicle uses staggered sizing, because front and rear tires cannot simply be treated as identical replacements. Looking over the tires before longer trips and during routine service helps catch alignment, suspension, or air-loss issues early. That supports proper handling and helps protect the wheel-and-tire package.
