The 2020 Mercedes-Benz Trucks GLE350 sits in the modern luxury SUV world, where ride quality, road manners, and a clean factory-style stance all matter as much as utility. Buyers looking at this exact model are usually balancing everyday drivability with the need to match the vehicle’s wheel package correctly. Tire fitment on the 2020 Mercedes-Benz Trucks GLE350 is entirely radial, but it is not a one-size setup, with 19-inch, 20-inch, and staggered 21-inch applications all in play. That makes wheel diameter and exact sub-model position especially important before choosing a tire. A careful match preserves appearance, clearance, and the intended driving character.
Which Tire Size Is Right for The 2020 Mercedes-Benz Trucks GLE350
The 2020 Mercedes-Benz Trucks GLE350 uses four tire sizes, and the right one depends first on the exact sub-model and wheel setup. All fitments are radial, but they span 19-inch, 20-inch, and 21-inch rims, including a staggered 21-inch front and rear arrangement. Before choosing a tire, confirm both the wheel diameter and whether the vehicle uses a square setup or separate front and rear sizes.
255/50R19 is a metric radial size where 255 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2020 Mercedes-Benz Trucks GLE350, this size serves one of the standard non-staggered applications and is tied to a 19-inch wheel package. Buyers considering this size should focus on matching the existing wheel diameter and maintaining the intended overall stance of the vehicle. It is the right place to start when the GLE350 is equipped with the smaller factory-style wheel setup.
275/50R20 follows the same metric radial format, with a 275-millimeter nominal section width, a 50-series profile, radial construction, and a 20-inch rim. For the 2020 Mercedes-Benz Trucks GLE350, this size is another square-fitment option rather than part of the staggered 21-inch arrangement. It gives the buyer a different wheel-package path than the 19-inch setup, so the key decision is confirming the actual wheel diameter already on the vehicle. This size should be evaluated as its own fitment, not as a casual substitute for the 19-inch or 21-inch applications.
275/45R21 is a metric radial size that uses a 275-millimeter nominal section width, a 45-series aspect ratio, and a 21-inch rim. On the 2020 Mercedes-Benz Trucks GLE350, this size is used in the front position on the staggered 21-inch setup. Its role is distinct from the square 19-inch and 20-inch applications, because it is paired with a different rear size rather than repeated at all four corners. Buyers should verify that the vehicle actually has the staggered front fitment before selecting this size, especially if wheels have ever been changed.
315/40R21 is a wider metric radial size, with 315 indicating nominal section width in millimeters, 40 identifying the aspect ratio, and 21 showing the wheel diameter. On the 2020 Mercedes-Benz Trucks GLE350, this size is the rear companion to the staggered 21-inch front fitment. Its purpose is tied to that specific rear-wheel application, so it should not be treated as a universal 21-inch choice for the model. The practical step is confirming that the vehicle uses the staggered setup and that the rear wheels match this size requirement before replacement.
Sub-model fitment on the 2020 Mercedes-Benz Trucks GLE350 varies by wheel package and, in some cases, by front and rear position. Checking the exact sub-model name matters here because some versions use a square setup while others use a staggered 21-inch arrangement.

2020 Mercedes-Benz Trucks GLE350 4Matic
The 2020 Mercedes-Benz Trucks GLE350 4Matic uses either a 255/50R19 or 275/50R20 radial fitment, depending on the wheel package. Tire selection starts with confirming whether the vehicle is on 19-inch or 20-inch wheels so the replacement matches the existing setup.
The 2020 Mercedes-Benz Trucks GLE350 4Matic Front uses 275/45R21 in radial construction as part of a staggered arrangement. That means the front tire should be chosen with the matching rear setup in mind rather than as part of a four-corner square fitment.
The 2020 Mercedes-Benz Trucks GLE350 4Matic Rear uses 315/40R21, paired with a different front size on the staggered 21-inch setup. Rear tire replacement should be handled as a position-specific fitment, with wheel width and front-to-rear pairing checked carefully.
The 2020 Mercedes-Benz Trucks GLE350 Base follows the same square-fitment pattern as the 4Matic, using either 255/50R19 or 275/50R20 radial tires. The deciding factor is the actual wheel package on the vehicle, not simply the model name on the badge.
The 2020 Mercedes-Benz Trucks GLE350 Base Front uses 275/45R21 when equipped with the staggered 21-inch setup. Front tire selection should stay tied to that specific arrangement so the overall fitment remains consistent with the rear axle.
The 2020 Mercedes-Benz Trucks GLE350 Base Rear uses 315/40R21 in the rear position of the staggered 21-inch package. Choosing this size correctly means confirming that the vehicle is not running a square 19-inch or 20-inch setup instead.
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 GLE350 usually need clarity on exact tire size, wheel diameter, staggered versus square fitment, and what to inspect before driving. These answers focus on fitment, tire selection, and practical road-use checks for this specific model.
Tire Size & Fitment
What tire size fits a 2020 Mercedes-Benz Trucks GLE350?
The 2020 Mercedes-Benz Trucks GLE350 uses 255/50R19, 275/50R20, 275/45R21, and 315/40R21, depending on the exact sub-model and wheel arrangement. The 19-inch and 20-inch sizes are square applications, while the 21-inch fitment is staggered with one size in front and a different size in the rear.
The important step is matching the replacement tire to the wheel package already on the vehicle. A GLE350 with 19-inch wheels does not use the same tire as one with 20-inch wheels, and a staggered 21-inch setup requires separate front and rear sizes. Checking the door placard, current tire sidewalls, and actual wheel diameter helps avoid a mismatch.
What size rim does a 2020 Mercedes-Benz Trucks GLE350 use?
The 2020 Mercedes-Benz Trucks GLE350 uses 19-inch, 20-inch, and 21-inch rim diameters, depending on the configuration. The 255/50R19 size mounts on a 19-inch rim, 275/50R20 uses a 20-inch rim, and both 275/45R21 and 315/40R21 are part of a 21-inch staggered setup.
Rim diameter should be confirmed before anything else because tire sizes are not interchangeable across these wheel sizes. A 19-inch tire cannot be mounted on a 20-inch or 21-inch wheel, and the same principle applies across the rest of the range. If the GLE350 has aftermarket wheels, verify the actual wheel markings rather than relying only on model name.
Why does the 2020 Mercedes-Benz Trucks GLE350 have more than one tire size?
More than one tire size applies because the 2020 Mercedes-Benz Trucks GLE350 was fitted with different wheel packages. Some versions use a square setup with the same size at all four corners, while others use a staggered 21-inch arrangement with 275/45R21 in front and 315/40R21 in the rear.
That means tire selection depends on the exact wheel and axle position, not just the model year and name. A buyer should confirm whether the SUV has 19-inch, 20-inch, or staggered 21-inch wheels before choosing tires. Looking at the current tire sidewalls and checking front and rear sizes separately is especially important on the staggered version.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Mercedes-Benz Trucks GLE350?
Start with the correct tire size for the exact wheel package on the 2020 Mercedes-Benz Trucks GLE350. This model uses only radial tires, but it spans 255/50R19, 275/50R20, and a staggered 21-inch combination of 275/45R21 front and 315/40R21 rear, so the first decision is always matching the existing setup.
After that, look at whether the vehicle uses a square or staggered arrangement and confirm that front and rear tires are being replaced correctly. It also helps to inspect the current wheels for any aftermarket changes that could affect width or clearance. Choosing within the right size keeps the vehicle’s intended stance, drivability, and fitment relationship intact.
How do I choose between the available tire sizes for a 2020 Mercedes-Benz Trucks GLE350?
The correct choice is not a matter of preference between the four sizes, because each one belongs to a specific wheel package or axle position on the 2020 Mercedes-Benz Trucks GLE350. A 255/50R19 or 275/50R20 suits square setups, while 275/45R21 front and 315/40R21 rear belong to the staggered 21-inch application.
A good approach is to confirm the wheel diameter first, then compare front and rear tire markings to see whether the SUV uses identical sizes at all four corners. That prevents buying by appearance alone. On vehicles that have seen wheel swaps, measuring the actual wheel and reviewing existing fitment is more reliable than assuming every GLE350 is equipped the same way.
What rim-fitment details should I compare when choosing 2020 Mercedes-Benz Trucks GLE350 tires?
The main rim-fitment detail is wheel diameter, since the 2020 Mercedes-Benz Trucks GLE350 uses 19-inch, 20-inch, and 21-inch applications. The 21-inch setup also needs front-versus-rear confirmation because it is staggered, with one size assigned to the front axle and a wider size assigned to the rear.
It is also smart to verify that the wheel itself matches the tire position being replaced, especially if the vehicle has been modified or wheels have been rotated incorrectly in the past. Checking the current tire sidewall, wheel stampings, and axle location helps keep the replacement aligned with the SUV’s actual configuration rather than a general model description.
Restoration & Appearance
Does correct tire fitment matter for the appearance of a 2020 Mercedes-Benz Trucks GLE350?
Yes, correct tire fitment has a visible effect on how a 2020 Mercedes-Benz Trucks GLE350 sits and presents itself. The model’s wheel packages use different diameters and, in the 21-inch application, different front and rear sizes, so the wrong tire can upset the proportional look as well as the intended fit on the wheel.
Appearance is not just about style; it is also tied to the relationship between tire size, wheel diameter, and axle position. Keeping the proper 19-inch, 20-inch, or staggered 21-inch fitment preserves the clean factory-style presentation most owners want. When exact visual authenticity matters, compare the vehicle’s current setup against original wheel-package documentation before changing sizes.
Which tire setup suits a factory-style 2020 Mercedes-Benz Trucks GLE350 appearance?
A factory-style appearance starts with staying with the correct tire size for the wheel package already on the 2020 Mercedes-Benz Trucks GLE350. That means using 255/50R19 or 275/50R20 on square setups, or keeping the 275/45R21 front and 315/40R21 rear combination on a staggered 21-inch vehicle.
The key is resisting the urge to mix wheel-package sizes or treat the front and rear 21-inch tires as interchangeable. Keeping the original-style diameter relationship helps the SUV retain the stance and visual balance intended for that configuration. If the vehicle has changed hands or has aftermarket wheels, confirm what is actually installed before choosing replacement tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Mercedes-Benz Trucks GLE350?
Yes, modifications can affect tire fitment on a 2020 Mercedes-Benz Trucks GLE350 even when the tire size sounds close to stock. Aftermarket wheels, altered offsets, suspension changes, lowering, or body modifications can change how much room the tire has at the fender, inner wheelhouse, and steering components.
That is especially important on the staggered 21-inch setup, where front and rear sizes already serve different roles. A GLE350 with non-stock wheels should have its actual wheel diameter and axle-specific fitment checked before replacement. Looking at clearance through full steering travel and under normal suspension load helps catch issues before road use.
What should I inspect before driving a 2020 Mercedes-Benz Trucks GLE350 on new tires?
Before driving, inspect that each new tire matches the correct size for its wheel and axle position on the 2020 Mercedes-Benz Trucks GLE350. Check inflation pressure, verify there is no contact at the fender or suspension, and make sure the staggered 21-inch setup, if present, has the front and rear tires installed in the proper locations.
A short visual inspection can prevent larger problems on the road. Look for valve-stem issues, uneven bead seating, cuts, bulges, or signs of rubbing after the first miles of use. It also helps to recheck wheel hardware and confirm that the vehicle tracks normally, especially if the tires were installed after wheel changes or recent suspension work.
What should I check before a longer drive in a 2020 Mercedes-Benz Trucks GLE350?
Before a longer drive, confirm that the 2020 Mercedes-Benz Trucks GLE350 is wearing the correct tire size on each corner and that tire pressures are set properly for the vehicle’s use. Inspect tread and sidewalls for damage, verify there is no slow air loss, and make sure any staggered 21-inch setup still has the correct front and rear pairing.
Longer trips put more emphasis on basic condition than many low-mile vehicles receive in day-to-day use. It is smart to look for cracking, punctures, bulges, and uneven wear, then check that the wheels are free of visible damage. On a vehicle with recent wheel or suspension changes, a final clearance check adds another layer of confidence before setting out.
