The 2017 Mercedes-Benz Trucks GLE550e brought plug-in hybrid power into a midsize luxury SUV format, blending everyday road manners with the added weight and complexity of an electrified drivetrain. Buyers looking at one today are often balancing luxury-SUV comfort with practical replacement fitment that still suits the vehicle’s original character. This model uses radial tires in either 255/50R19 or 265/45R20 sizing, so the first step is confirming which wheel diameter is actually on the vehicle. That choice shapes sidewall height, tire profile, and the replacement path ahead. For a proper match, wheel size and the vehicle’s current setup matter more than broad make-or-model assumptions.
Which Tire Size Is Right for The 2017 Mercedes-Benz Trucks GLE550e
The 2017 Mercedes-Benz Trucks GLE550e uses two primary tire sizes, and the difference starts with wheel diameter: one setup uses a 19-inch rim and the other uses a 20-inch rim. The GLE550e 4Matic can be found with either size, so confirming the actual wheel on the vehicle is the first step before comparing tire options, profile, and overall replacement approach.
A 255/50R19 tire is a metric radial size with a 255-millimeter nominal section width, a 50-series aspect ratio, and fitment for a 19-inch rim. On the 2017 Mercedes-Benz Trucks GLE550e, this size delivers a modern radial construction suited to the vehicle’s luxury-SUV road use and hybrid weight demands. Buyers familiar with current replacement tires will recognize this as a contemporary sizing format rather than a vintage code. This size is the right one to evaluate only when the vehicle is equipped with 19-inch wheels, making wheel confirmation the key first check.
A 265/45R20 tire is a metric radial size that uses a 265-millimeter nominal section width, a 45-series aspect ratio, and a 20-inch rim diameter. For the 2017 Mercedes-Benz Trucks GLE550e, it represents the larger wheel fitment and a slightly lower-profile presentation than the 19-inch setup. The radial construction matches the vehicle’s modern design and intended on-road use. This size should be considered only on vehicles already equipped with 20-inch wheels, since the wheel diameter itself determines whether this fitment belongs on your GLE550e.
Fitment is straightforward here because the covered sub-model shares the same two primary tire-size paths. What matters most is not trim identification alone, but confirming whether the vehicle is on 19-inch or 20-inch wheels before selecting a replacement tire.

Frequently Asked Questions
These FAQs focus on the two tire sizes used on the 2017 Mercedes-Benz Trucks GLE550e, along with wheel-diameter confirmation, sub-model fitment, replacement-tire selection, and the basic checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2017 Mercedes-Benz Trucks GLE550e?
The 2017 Mercedes-Benz Trucks GLE550e uses two primary tire sizes: 255/50R19 and 265/45R20. Both are radial tire fitments, and both are associated with the GLE550e 4Matic, so the correct choice depends on which wheel diameter is currently on the vehicle rather than on a separate tire-construction decision.
The practical step is to confirm whether the SUV has 19-inch or 20-inch wheels before ordering tires. Even though both sizes belong to this model, they are not interchangeable without the matching wheel diameter. It is also smart to verify that the vehicle has not been changed with aftermarket wheels or other fitment-altering modifications.
What size rim does a 2017 Mercedes-Benz Trucks GLE550e use?
A 2017 Mercedes-Benz Trucks GLE550e uses either a 19-inch rim with 255/50R19 tires or a 20-inch rim with 265/45R20 tires. The tire size itself identifies the wheel diameter, so the final number in each size code is the rim size the tire is built to fit.
That makes wheel confirmation the first and most important fitment check on this vehicle. A tire built for a 19-inch rim cannot be mounted on a 20-inch wheel, and the reverse is also true. Looking at the current sidewall size marking is usually the quickest way to confirm which wheel-and-tire combination the GLE550e is using.
Why does the 2017 Mercedes-Benz Trucks GLE550e have more than one tire size?
The 2017 Mercedes-Benz Trucks GLE550e appears with two factory-style fitment paths because it can be equipped with either 255/50R19 or 265/45R20 tires. Both belong to the GLE550e 4Matic, and the difference centers on the wheel diameter paired with the vehicle rather than on one size replacing the other.
In practical terms, that means the vehicle must be matched to the wheel setup it actually has today. A 19-inch and a 20-inch package can change tire profile and overall presentation, so selection should begin with the mounted wheel size. Checking the existing tire sidewall and wheel before purchase prevents a simple but costly mismatch.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Mercedes-Benz Trucks GLE550e?
Start with the correct size for the wheel already on the vehicle: 255/50R19 for a 19-inch rim or 265/45R20 for a 20-inch rim. Since both sizes are radial fitments for the 2017 Mercedes-Benz Trucks GLE550e, the main selection factors are proper size matching, wheel compatibility, and choosing a tire suited to the SUV’s intended road use.
It also helps to look beyond the size stamp and consider the vehicle’s current condition. A GLE550e with replacement wheels, altered ride height, or unusual wear patterns deserves an extra clearance and alignment check before new tires go on. Matching the tire to the wheel and the vehicle’s actual setup is more important than choosing by size name alone.
How do I choose between the available 255/50R19 and 265/45R20 tires for a 2017 Mercedes-Benz Trucks GLE550e?
The choice between 255/50R19 and 265/45R20 is not a matter of preference alone, because each tire size belongs to a different wheel diameter. The 255/50R19 fits a 19-inch rim, while the 265/45R20 fits a 20-inch rim, so the correct tire is the one that matches the wheels already installed on the GLE550e.
Once that is confirmed, compare replacement tires within the correct size rather than jumping between the two fitments. Looking at the wrong size can create confusion about profile, appearance, and compatibility. Checking the sidewall markings on the current tires and verifying the wheel diameter keeps the buying process focused on what actually fits the vehicle’s present setup.
What rim-fitment details should I compare when choosing 2017 Mercedes-Benz Trucks GLE550e tires?
The key rim-fitment detail on a 2017 Mercedes-Benz Trucks GLE550e is diameter, because the vehicle uses either 19-inch or 20-inch wheels depending on the tire size. A 255/50R19 belongs on a 19-inch rim, and a 265/45R20 belongs on a 20-inch rim, so size-to-wheel matching comes first.
Beyond diameter, it is wise to confirm that the wheels on the vehicle are the ones the tires are intended for, especially if the SUV has been modified. Aftermarket wheels can change width, offset, and clearance, which may affect how a replacement tire sits and performs. A quick wheel and clearance check helps avoid fitment surprises after installation.
Restoration & Appearance
Does correct tire fitment matter for a 2017 Mercedes-Benz Trucks GLE550e restoration or preservation project?
Yes, correct tire fitment still matters on a 2017 Mercedes-Benz Trucks GLE550e, even though it is a modern vehicle rather than a vintage restoration subject. Using the proper 255/50R19 or 265/45R20 size for the wheel on the vehicle helps preserve the intended stance, profile, and overall presentation of the SUV.
For a preservation-minded owner, consistency often matters more than experimentation. A GLE550e kept close to its original configuration should stay with the wheel diameter and matching tire size it currently uses unless there is a clear reason to change. That approach keeps the vehicle’s appearance and fitment relationship more in line with its original modern design intent.
How does tire size affect the appearance of a 2017 Mercedes-Benz Trucks GLE550e?
Tire size affects the appearance of a 2017 Mercedes-Benz Trucks GLE550e because the two fitments pair with different wheel diameters and different sidewall proportions. The 255/50R19 setup uses a 19-inch wheel, while the 265/45R20 setup uses a 20-inch wheel with a lower-profile tire shape.
That means the SUV can present a slightly different visual balance depending on which wheel-and-tire package it carries. For an owner focused on maintaining the vehicle’s established look, the best path is to replace tires in the same size already fitted to the vehicle. Confirming the existing sidewall marking keeps the appearance consistent and the fitment straightforward.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz Trucks GLE550e?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz Trucks GLE550e even when the tire size appears correct on paper. Wheel changes, offset differences, suspension alterations, or body modifications can all influence how a 255/50R19 or 265/45R20 tire sits in the wheel opening and how much clearance it has in use.
That is why a modified vehicle should be checked as an actual package, not just by the original size chart. Steering clearance, suspension travel, and fender room all matter once the vehicle departs from stock wheel or suspension dimensions. A careful inspection before mounting new tires can prevent rubbing, clearance issues, and unnecessary return problems.
What should I inspect before driving a 2017 Mercedes-Benz Trucks GLE550e on new tires?
Before driving a 2017 Mercedes-Benz Trucks GLE550e on new tires, inspect the tire size against the wheel diameter, confirm proper inflation, and look over the wheels themselves for damage or irregularities. It is also smart to check that the tires are seated correctly and that there are no obvious clearance concerns at the suspension or fender edges.
A short follow-up inspection after initial driving is just as useful. Uneven wear, vibration, or signs of rubbing can point to alignment issues, wheel problems, or a vehicle setup that needs attention. Catching those issues early helps protect the new tires and gives the GLE550e a more stable, predictable road feel from the start.
How often should tires on a 2017 Mercedes-Benz Trucks GLE550e be inspected?
Tires on a 2017 Mercedes-Benz Trucks GLE550e should be inspected regularly, not only when replacement time arrives. Routine checks should include inflation, tread condition, cuts, bulges, irregular wear, and any signs that one tire is losing air faster than the others, especially on a heavier modern SUV with performance-oriented sizing.
A monthly visual inspection is a sensible habit, and an extra check before a longer drive adds another layer of protection. Vehicles that sit for extended periods also deserve attention, since low use does not prevent aging or air loss. Consistent inspections help catch small problems before they become handling, comfort, or safety concerns on the road.
