The 2016 Mercedes-Benz Trucks GLE300d sits in the modern luxury SUV era, where daily comfort, long-distance stability, and upscale road manners all matter as much as utility. As part of the GLE family, it carries a more contemporary tire fitment story than an older collector vehicle, with multiple radial sizes tied to different wheel diameters. This model uses 255/55R18, 255/50R19, and 265/45R20 tire sizes, all in radial construction. That makes the key decision less about bias-ply versus radial and more about confirming the exact wheel package already on the vehicle. Before choosing a replacement, verify rim diameter, overall stance, and whether the SUV still retains its original wheel setup.
Which Tire Size Is Right for The 2016 Mercedes-Benz Trucks GLE300d
The 2016 Mercedes-Benz Trucks GLE300d uses three primary tire sizes, and they differ by wheel diameter rather than construction type. All three are radial fitments, so the first step is confirming whether the vehicle is on 18-inch, 19-inch, or 20-inch wheels. Once that is settled, the decision becomes choosing the right replacement within the correct size for the vehicle's existing setup and intended road use.
255/50R19 is a metric radial size in which 255 identifies the nominal section width in millimeters, 50 is the aspect ratio, R designates radial construction, and 19 is the rim diameter in inches. On the 2016 Mercedes-Benz Trucks GLE300d, this size belongs to a 19-inch wheel setup and reflects a modern SUV fitment rather than a vintage numeric or alphanumeric system. Its proportions place it in the middle of this model's three size choices. For replacement, confirm that the vehicle is actually equipped with 19-inch wheels before comparing tire options in this size.
255/55R18 is a metric radial size with a 255-millimeter nominal section width, a 55-series aspect ratio, radial construction, and an 18-inch rim diameter. For the 2016 Mercedes-Benz Trucks GLE300d, it is part of the 18-inch wheel fitment and shares the same general width as the 255/50R19 while using a different wheel diameter and profile. That makes wheel confirmation essential before replacement. Buyers considering this size should match it to the existing 18-inch setup and inspect the wheel width and overall condition before mounting new tires.
265/45R20 is a metric radial size where 265 is the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2016 Mercedes-Benz Trucks GLE300d, this size is tied to the 20-inch wheel package and stands apart from the 18-inch and 19-inch fitments by both width and rim diameter. It should be selected only for vehicles already using the 20-inch wheel setup. Wheel diameter, wheel width, and clearance should all be checked before choosing a replacement in this size.
The covered sub-model fitment is straightforward in one sense and still important in another. The GLE300d 4Matic can use more than one tire size, so identifying the exact wheel package on the vehicle matters more than the sub-model name alone.

Frequently Asked Questions
Tire questions for the 2016 Mercedes-Benz Trucks GLE300d usually come down to size selection, wheel diameter confirmation, and maintaining the correct radial fitment. The FAQs below focus on choosing among the three primary sizes, checking wheel setup, and preparing the vehicle for safe road use.
Tire Size & Fitment
What tire size fits a 2016 Mercedes-Benz Trucks GLE300d?
The 2016 Mercedes-Benz Trucks GLE300d uses three primary tire sizes: 255/55R18, 255/50R19, and 265/45R20. All three are radial sizes, and each one corresponds to a different wheel diameter rather than a different tire construction style.
The practical next step is to confirm which wheels are actually on the vehicle before choosing a replacement tire. A GLE300d that is on 18-inch wheels needs 255/55R18, while 19-inch and 20-inch wheel setups require their own matching sizes. Checking the sidewall of the current tire and the wheel itself helps prevent ordering the wrong size.
What size rim does a 2016 Mercedes-Benz Trucks GLE300d use?
The 2016 Mercedes-Benz Trucks GLE300d uses 18-inch, 19-inch, or 20-inch rims, depending on which tire size is on the vehicle. The three matched combinations are 255/55R18 on an 18-inch rim, 255/50R19 on a 19-inch rim, and 265/45R20 on a 20-inch rim.
Rim diameter is the first fitment detail to verify because a tire must match the wheel diameter exactly. Once diameter is confirmed, it also helps to inspect wheel width, check for aftermarket replacements, and make sure the vehicle has enough clearance for the tire size already associated with that wheel package.
Why does the 2016 Mercedes-Benz Trucks GLE300d have more than one tire size?
More than one tire size appears on the 2016 Mercedes-Benz Trucks GLE300d because the model can be equipped with different wheel diameters. The three sizes are tied to 18-inch, 19-inch, and 20-inch wheel setups, all within the same radial-construction fitment family.
That means the correct replacement is determined by the wheel package on the individual vehicle, not by year, make, and model alone. Before replacing tires, inspect the existing sidewall markings, confirm the wheel diameter, and account for any wheel or suspension changes that may have been made since the vehicle was new.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Mercedes-Benz Trucks GLE300d?
Start with the correct size for the wheel package already on the vehicle: 255/55R18, 255/50R19, or 265/45R20. Because all three fitments are radial, the main selection factors are proper size matching, wheel compatibility, and choosing a tire suited to the vehicle's intended road use.
Beyond size, inspect the wheel condition, confirm the vehicle has a matching set where required, and make sure any replacement keeps the setup appropriate for the SUV's stance and clearance. It also helps to review load-related specifications, compare tire dimensions within the chosen size, and account for any non-original wheels before finalizing a choice.
How do I choose between the available 2016 Mercedes-Benz Trucks GLE300d tire sizes?
The three sizes are not interchangeable choices to pick by preference alone. Each one belongs to a specific wheel diameter, so the correct size is determined by whether the 2016 Mercedes-Benz Trucks GLE300d is equipped with 18-inch, 19-inch, or 20-inch wheels.
A useful approach is to verify the size molded into the current tire sidewall and compare it with the wheel diameter before shopping. That keeps the decision focused on the right replacement size first. After that, compare tire specifications within that size rather than trying to move to another size without checking wheel and clearance requirements.
What rim-fitment details should I compare when choosing 2016 Mercedes-Benz Trucks GLE300d tires?
Rim diameter is the most important detail because each approved tire size for the 2016 Mercedes-Benz Trucks GLE300d is tied to a different wheel size. A 255/55R18 requires an 18-inch rim, a 255/50R19 requires a 19-inch rim, and a 265/45R20 requires a 20-inch rim.
Wheel width, wheel condition, and whether the SUV still has its original wheel package also deserve attention. A vehicle with aftermarket wheels may not match the original setup exactly, even if the sidewall size looks close. Checking diameter, width, and clearance together helps keep the fitment decision grounded in the actual vehicle.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Mercedes-Benz Trucks GLE300d restoration or refurbishment?
Yes, correct tire fitment still matters on a 2016 Mercedes-Benz Trucks GLE300d, even though it is a modern vehicle rather than a vintage restoration subject. Using the proper size for the wheel package helps preserve the SUV's intended stance, wheel-to-tire relationship, and overall appearance.
A refurbishment-focused owner should avoid treating the three sizes as cosmetic alternatives. The 18-inch, 19-inch, and 20-inch fitments each belong to different wheel setups, so appearance and fitment go together. Matching the tire size to the wheel package already on the vehicle is the best starting point before addressing finer visual details.
How does tire size affect the appearance of a 2016 Mercedes-Benz Trucks GLE300d?
Tire size has a visible effect on the 2016 Mercedes-Benz Trucks GLE300d because each approved fitment pairs with a different wheel diameter. An 18-inch setup presents differently from a 19-inch or 20-inch setup, even though all three are legitimate radial fitments for this model.
Appearance should be evaluated as part of the complete wheel-and-tire package, not as an isolated size change. A different size can alter how much sidewall is visible and how the wheel fills the opening, but any change should be checked carefully against the actual wheel, vehicle clearance, and the setup already on the SUV.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mercedes-Benz Trucks GLE300d?
Yes, modifications can affect tire fitment on a 2016 Mercedes-Benz Trucks GLE300d. Aftermarket wheels, suspension changes, ride-height alterations, or body modifications can all change the space available for the vehicle's original 255/55R18, 255/50R19, or 265/45R20 fitments.
That matters because the correct replacement tire is tied to both wheel diameter and the actual setup on the vehicle. An SUV that no longer has its original wheels may need extra verification before replacement. Checking wheel size, wheel width, steering clearance, and fender clearance helps prevent fitment surprises once the new tires are installed.
What should I inspect before driving a 2016 Mercedes-Benz Trucks GLE300d on new tires?
Before driving a 2016 Mercedes-Benz Trucks GLE300d on new tires, inspect the wheel condition, confirm the tire size matches the installed rim diameter, and make sure all four tires are properly mounted and inflated. It also helps to check for visible damage, uneven wear clues, and any issues that suggest alignment or suspension problems.
A short clearance check is worthwhile before normal driving, especially if the vehicle has non-original wheels or suspension changes. Turn the steering from lock to lock, look for rubbing points, and confirm the tires seat properly on the wheels. Catching those issues early helps protect both the tires and the vehicle.
What should I check before a longer drive in a 2016 Mercedes-Benz Trucks GLE300d?
Before a longer drive, verify that the 2016 Mercedes-Benz Trucks GLE300d is on the correct tire size for its wheel package and inspect each tire for cuts, bulges, cracking, or signs of air loss. Tread condition and inflation should be checked as part of the same walkaround.
Longer trips put more emphasis on consistency across the full set, so it is wise to look at wear patterns and confirm that nothing is rubbing under load or during steering movement. A vehicle that has sat for extended periods also deserves extra attention to tire age and condition before being asked to cover highway miles.
