The 2017 Mercedes-Benz Trucks GLE350 sits in the modern luxury SUV segment where comfort, road manners, and a substantial curb presence all depend heavily on proper tire fitment. Buyers looking at this exact model are usually balancing everyday drivability with the need to keep the vehicle's stance and wheel setup correct. The 2017 Mercedes-Benz Trucks GLE350 uses radial tire fitments in either 255/50R19 or 265/45R20, depending on the wheel package on the vehicle. That makes the real decision less about vintage-style construction and more about confirming rim diameter first, then choosing the right size for appearance, handling feel, and intended road use.
Which Tire Size Is Right for The 2017 Mercedes-Benz Trucks GLE350
Two primary tire sizes apply to the 2017 Mercedes-Benz Trucks GLE350, and both are radial fitments. The key first step is confirming whether the vehicle is running 19-inch or 20-inch wheels, since rim diameter determines which size belongs on it. Both the Base and 4Matic versions can use either size, so wheel setup matters more than sub-model name when selecting tires.
255/50R19 is a modern metric radial size in which 255 identifies the nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. On the 2017 Mercedes-Benz Trucks GLE350, this size suits vehicles equipped with 19-inch wheels and keeps the tire choice aligned with a contemporary SUV fitment. Its dimensions make it a practical reference point when matching replacement tires to the existing wheel package. Confirming the actual wheel diameter on the vehicle is still essential before selecting this size.
265/45R20 is also a modern metric radial size, with 265 indicating nominal section width in millimeters, 45 identifying the aspect ratio, R marking radial construction, and 20 showing the rim diameter in inches. For the 2017 Mercedes-Benz Trucks GLE350, this size belongs on vehicles fitted with 20-inch wheels rather than the 19-inch setup. It represents a different wheel-and-tire package rather than a casual alternate for every vehicle. Checking the current wheels before replacement helps avoid ordering a tire size that does not match the rim diameter already on the SUV.
Fitment is straightforward across the covered 2017 Mercedes-Benz Trucks GLE350 sub-models because both the Base and 4Matic can use the same two tire sizes. The important step is verifying which wheel diameter is actually on the vehicle, since that determines whether a 19-inch or 20-inch tire is required.

2017 Mercedes-Benz Trucks GLE350 4Matic
The 2017 Mercedes-Benz Trucks GLE350 4Matic can use either of the model's radial tire sizes, depending on whether it has the 19-inch or 20-inch wheel package. Tire selection starts with the installed wheels, then moves to choosing a replacement that matches the vehicle's existing fitment and intended road use.
The 2017 Mercedes-Benz Trucks GLE350 Base shares the same overall tire-fitment pattern, with radial options tied to either 19-inch or 20-inch wheels. That means the practical decision is confirming the wheel diameter on the vehicle first, then selecting the matching tire size rather than relying on the sub-model name alone.
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
These FAQs focus on the two correct tire sizes for the 2017 Mercedes-Benz Trucks GLE350, how wheel diameter affects fitment, and what to check when choosing replacement tires or inspecting the vehicle for regular road use.
Tire Size & Fitment
What tire size fits a 2017 Mercedes-Benz Trucks GLE350?
The 2017 Mercedes-Benz Trucks GLE350 uses two primary radial tire sizes: 255/50R19 and 265/45R20. Both the Base and 4Matic versions can use either size, so the correct choice depends on the wheel package installed on the vehicle rather than the sub-model name by itself.
Checking the tire sidewall or measuring the wheel diameter is the quickest way to confirm which size belongs on a particular GLE350. A 19-inch wheel requires 255/50R19, while a 20-inch wheel requires 265/45R20, and the two sizes should not be mixed casually without confirming the full wheel and vehicle setup.
What size rim does a 2017 Mercedes-Benz Trucks GLE350 use?
A 2017 Mercedes-Benz Trucks GLE350 uses either a 19-inch or 20-inch rim, depending on the wheel package on the vehicle. The 255/50R19 tire is paired with a 19-inch rim, and the 265/45R20 tire is paired with a 20-inch rim.
Rim diameter is the first fitment detail to verify before replacing tires on this model. Looking only at the vehicle badge is not enough, because both covered sub-models can appear with either wheel size, and a tire must match the actual rim diameter already mounted on the SUV.
Do all 2017 Mercedes-Benz Trucks GLE350 sub-models use the same tire size?
Both covered 2017 Mercedes-Benz Trucks GLE350 sub-models, Base and 4Matic, can use the same two tire sizes: 255/50R19 and 265/45R20. That means fitment does not split neatly by sub-model, since either version may be equipped with either wheel-and-tire package.
The practical takeaway is that the wheel setup on the individual vehicle matters more than the sub-model badge when ordering tires. Owners should confirm the size currently installed, verify the wheel diameter, and make sure all four tires match the intended package before replacing a single tire or a full set.
Choosing the Right Tire
What should I consider when choosing a 255/50R19 or 265/45R20 tire for a 2017 Mercedes-Benz Trucks GLE350?
Start with the correct size for the wheels already on the vehicle, since the 2017 Mercedes-Benz Trucks GLE350 uses either 255/50R19 or 265/45R20 radial tires. Choosing between them is not a style preference alone; each size belongs to a different rim diameter and wheel package.
Once the size is confirmed, compare the tire's intended use, overall dimensions, and how closely it matches the existing setup on the SUV. It also helps to inspect for aftermarket wheel changes, previous size substitutions, or suspension modifications that could affect clearance and how a replacement tire sits under the vehicle.
How do I choose between the available 2017 Mercedes-Benz Trucks GLE350 tire sizes?
The correct way to choose between the two sizes is by confirming whether the 2017 Mercedes-Benz Trucks GLE350 has 19-inch or 20-inch wheels. A vehicle with 19-inch rims uses 255/50R19, while a vehicle with 20-inch rims uses 265/45R20.
This is a fitment decision, not an upgrade shortcut, because the tire must match the wheel diameter exactly. If the SUV has been modified with different wheels than it originally carried, verify the wheel size stamped on the rim and compare the current tire size before purchasing replacements for daily driving or longer trips.
What rim-fitment details should I compare when choosing 2017 Mercedes-Benz Trucks GLE350 tires?
The main rim-fitment detail is diameter, because the 2017 Mercedes-Benz Trucks GLE350 uses either a 19-inch or 20-inch wheel. The tire size must match that diameter exactly, with 255/50R19 for 19-inch rims and 265/45R20 for 20-inch rims.
It is also smart to confirm that all four wheels match, especially on a used SUV where wheel swaps are common. Looking at the tire size on the sidewall, checking the wheel markings, and comparing the setup at each corner can prevent ordering a correct tire size for the wrong set of rims.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz Trucks GLE350?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz Trucks GLE350. Aftermarket wheels, altered offsets, suspension changes, or previous plus-size conversions can all change how a 255/50R19 or 265/45R20 tire sits in the wheel opening and how much clearance it has during turning or suspension travel.
A replacement tire should be matched to the wheel and vehicle as they exist now, not just to the stock application. Inspect the current wheels, verify the mounted tire size at all four corners, and check for rubbing marks, steering-clearance issues, or uneven tire wear before committing to a new set.
What should I inspect before driving a 2017 Mercedes-Benz Trucks GLE350 on new tires?
Before road use, inspect the wheels for damage, confirm the new tires match the correct size, and make sure inflation is set appropriately for the vehicle's operating conditions. It is also wise to check that the tires seat properly on the rims and that there are no visible cuts, bulges, or mounting issues.
A short follow-up inspection after initial driving is worthwhile, especially on a heavier SUV such as the 2017 Mercedes-Benz Trucks GLE350. Recheck air pressure, look for any signs of rubbing at full steering lock, and pay attention to vibration or pulling that could point to balancing, alignment, or fitment problems.
What should I check before a longer drive in a 2017 Mercedes-Benz Trucks GLE350?
Before a longer drive, confirm that the 2017 Mercedes-Benz Trucks GLE350 has a matching set of properly inflated tires in the correct size for its wheels. The tread and sidewalls should be inspected for cracking, punctures, bulges, or uneven wear, and the wheels themselves should be checked for any obvious damage.
Longer trips place more importance on small problems that may be easy to miss in local driving. Tire pressure, overall condition, and any signs of slow air loss deserve attention before departure, and it is smart to verify that no previous wheel change or suspension modification has reduced clearance around the installed tires.
