The 2016 Mercedes-Benz Trucks GLE550e sits at the point where luxury SUV engineering and plug-in hybrid performance began to converge in a serious way. Buyers drawn to this model are usually balancing comfort, road manners, and the clean, substantial stance that defines the vehicle. Tire selection matters because the GLE550e uses radial fitments in two different sizes, 255/50R19 and 265/45R20, each tied to a different wheel diameter. That makes wheel confirmation the first step before choosing a replacement tire. Once the correct size is established, the focus shifts to maintaining the right overall look, preserving proper fitment, and matching the vehicle's intended street use.
Which Tire Size Is Right for The 2016 Mercedes-Benz Trucks GLE550e
The 2016 Mercedes-Benz Trucks GLE550e uses two primary tire sizes, and the key difference is wheel diameter: 255/50R19 fits a 19-inch rim, while 265/45R20 fits a 20-inch rim. Because the same 4Matic sub-model can appear with either size, the first step is confirming which wheels are actually on the vehicle before comparing replacement tires.
255/50R19 is a metric radial size in which 255 identifies the nominal section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 19 is the rim diameter in inches. On the 2016 Mercedes-Benz Trucks GLE550e, this size supports the vehicle's modern SUV fitment with a 19-inch wheel. Its sizing format is familiar to current replacement-tire buyers and keeps the selection process centered on matching the existing wheel setup. This is the size to evaluate if the vehicle is riding on 19-inch rims and you want to preserve the intended dimensions.
265/45R20 is a metric radial size where 265 denotes nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 20 identifies the rim diameter in inches. For the 2016 Mercedes-Benz Trucks GLE550e, this fitment is tied to a 20-inch wheel and should be treated as a separate wheel-and-tire package from the 19-inch option. The slightly wider, lower-profile format changes the tire's sizing character even though overall diameter remains close. This is the correct path to follow when the vehicle is already equipped with 20-inch wheels.
Sub-model fitment is straightforward here because the covered configuration is the 2016 Mercedes-Benz Trucks GLE550e 4Matic, but tire choice still depends on wheel diameter. Since this sub-model can use either of the two radial sizes, checking the actual wheel setup matters more than trim identification alone.

Frequently Asked Questions
Questions about 2016 Mercedes-Benz Trucks GLE550e tires usually come down to identifying the correct wheel diameter, understanding the two radial sizes, and checking fitment, condition, and maintenance before regular road use.
Tire Size & Fitment
What tire size fits a 2016 Mercedes-Benz Trucks GLE550e?
The 2016 Mercedes-Benz Trucks GLE550e uses two primary tire sizes: 255/50R19 and 265/45R20. Both are radial sizes, and both apply to the GLE550e 4Matic, with the correct choice determined by the wheel diameter currently on the vehicle.
That means the first step is not choosing between two interchangeable tire sizes, but confirming whether the vehicle has 19-inch or 20-inch wheels. Checking the sidewall of the current tires and verifying the wheel size directly helps avoid ordering the wrong fitment for the vehicle's existing setup.
What size rim does a 2016 Mercedes-Benz Trucks GLE550e use?
A 2016 Mercedes-Benz Trucks GLE550e uses either a 19-inch or 20-inch rim, depending on which tire size is on the vehicle. The 255/50R19 size fits a 19-inch rim, while the 265/45R20 size fits a 20-inch rim.
Rim diameter is the most important fitment check on this vehicle because the two tire sizes are tied to different wheels. Before replacing tires, confirm the actual wheel size on the SUV rather than relying only on model identification, especially if the vehicle has had wheel changes at some point in its life.
Why does the 2016 Mercedes-Benz Trucks GLE550e have more than one tire size?
The 2016 Mercedes-Benz Trucks GLE550e has more than one tire size because it can be equipped with different wheel diameters. In this case, the two primary fitments are 255/50R19 and 265/45R20, both used on the GLE550e 4Matic.
This is a wheel-package difference rather than a sign of conflicting fitment. The practical takeaway is simple: identify the wheel diameter first, then stay with the tire size matched to that wheel. Trying to choose by model name alone can create confusion when the same sub-model appears with more than one valid size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Mercedes-Benz Trucks GLE550e?
Start with the correct size and wheel diameter. A 2016 Mercedes-Benz Trucks GLE550e uses either 255/50R19 or 265/45R20, both in radial construction, so the first requirement is matching the tire to the wheel currently on the vehicle.
After that, compare the tire's intended use with how the SUV is driven. Street-focused comfort, seasonal mileage, and preserving the vehicle's existing look all matter, but none of those choices override basic fitment. Wheel diameter, clearance, and the condition of the current suspension and alignment should all be checked before settling on a replacement.
How do I choose between the available 255/50R19 and 265/45R20 tires for a 2016 Mercedes-Benz Trucks GLE550e?
You do not choose between 255/50R19 and 265/45R20 as preference options unless the wheel setup is also being changed. Each size belongs to a different rim diameter, so the correct tire is the one that matches the wheels already installed on the 2016 Mercedes-Benz Trucks GLE550e.
Once the wheel size is confirmed, compare replacement tires within that one size rather than across both. Keeping the existing wheel package simplifies fitment and helps maintain the intended dimensions. Any move from 19-inch to 20-inch wheels, or the reverse, should be treated as a full wheel-and-tire change and checked carefully for compatibility.
What rim-fitment details should I compare when choosing 2016 Mercedes-Benz Trucks GLE550e tires?
The main rim-fitment detail is diameter. On a 2016 Mercedes-Benz Trucks GLE550e, 255/50R19 belongs on a 19-inch wheel and 265/45R20 belongs on a 20-inch wheel, so the tire and wheel must match exactly at that basic level.
Beyond diameter, it helps to confirm the actual wheel setup on the vehicle, especially if it has ever had aftermarket wheels installed. Width, offset, and clearance can all influence how a replacement tire sits and operates, even when the size on the sidewall appears correct for the model.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Mercedes-Benz Trucks GLE550e restoration or preservation project?
Yes, correct tire fitment matters because the 2016 Mercedes-Benz Trucks GLE550e uses specific modern radial sizes tied to two different wheel diameters. Keeping the right size on the right wheel helps preserve the vehicle's intended stance, wheel-to-tire proportion, and overall presentation.
For a preservation-minded owner, appearance and fitment usually work together. A tire that matches the existing wheel package keeps the vehicle looking properly sorted, while an incorrect size can change visual balance and create clearance concerns. If originality is especially important, compare the current setup against authoritative vehicle-specific reference material before changing wheel size.
How does tire sizing affect the appearance of a preserved 2016 Mercedes-Benz Trucks GLE550e?
Tire sizing has a visible effect because the 2016 Mercedes-Benz Trucks GLE550e uses either 255/50R19 or 265/45R20, and each size pairs with a different wheel diameter. Even with similar overall proportions, the 19-inch and 20-inch packages present the SUV differently.
For an owner focused on maintaining the vehicle's established look, the safest approach is usually to match the wheel-and-tire combination already on the SUV. That keeps the visual relationship between sidewall height and wheel size consistent, while also avoiding unnecessary fitment questions that can arise from changing packages.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mercedes-Benz Trucks GLE550e?
Yes, modifications can affect tire fitment on a 2016 Mercedes-Benz Trucks GLE550e. Even though the primary sizes are 255/50R19 and 265/45R20, aftermarket wheels, suspension changes, ride-height changes, or body alterations can change the space available around the tire.
A vehicle that has been lowered, fitted with different wheel offsets, or altered for appearance may need more careful checking before replacement tires are chosen. Steering clearance, inner-fender space, and the relationship between the tire and suspension components are all worth verifying so the selected size works with the actual setup on the SUV.
What should I inspect before driving a 2016 Mercedes-Benz Trucks GLE550e on new tires?
Inspect the wheels, valve stems, and overall condition of the mounting surfaces before driving on new tires. It also helps to confirm that the 2016 Mercedes-Benz Trucks GLE550e is wearing the correct size for its wheel package, either 255/50R19 or 265/45R20.
After installation, pay attention to inflation pressure, any signs of air loss, and whether the tires clear normally during full steering movement. A quick check of alignment condition, suspension wear, and unusual vibration can prevent premature tire wear and help the new set perform as intended on regular road use.
How often should tires on a 2016 Mercedes-Benz Trucks GLE550e be inspected?
Tires on a 2016 Mercedes-Benz Trucks GLE550e should be inspected regularly, especially if the vehicle sees mixed-use driving or spends long periods parked between trips. Routine checks should include tread condition, sidewall condition, air pressure, and any visible cuts, bulges, or irregular wear.
Periodic inspection matters just as much as choosing the correct size. Catching slow air loss, edge wear, or age-related cracking early can prevent larger problems and helps confirm that the suspension, alignment, and wheel setup are all working properly with the installed 255/50R19 or 265/45R20 tires.
