The 2017 Mercedes-Benz Trucks GLE400 sits in the modern luxury SUV category, blending everyday road comfort with the presence and performance expected from a premium German utility vehicle. Buyers looking at one today are often balancing original-style fitment, road manners, and the realities of replacement on a vehicle that may still serve daily-duty or enthusiast-owned use. This application uses a 265/45R20 radial tire on a 20-inch rim. That makes the main decision less about sorting through multiple factory sizes and more about choosing the right tire within that fitment. Wheel condition, overall tire dimensions, and the vehicle's current setup should all be confirmed before replacement.
Which Tire Size Is Right for The 2017 Mercedes-Benz Trucks GLE400
The 2017 Mercedes-Benz Trucks GLE400 uses one primary tire size: 265/45R20, a radial tire for a 20-inch rim. The covered 4Matic sub-model shares that same fitment, so the real choice is selecting the right tire within that size and confirming that the wheels and overall vehicle setup still match the original fitment before installation.
265/45R20 is a metric radial size in which 265 identifies the nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter in inches. On the 2017 Mercedes-Benz Trucks GLE400, this is the primary road-use fitment and matches the vehicle's 20-inch wheel setup. With an overall diameter of 29.39 inches and a section width of 10.43 inches, it is important to keep the replacement tire aligned with the vehicle's intended dimensions. This size is the right starting point when maintaining proper wheel compatibility, clearance, and everyday driving behavior.
Sub-model fitment is straightforward here because the covered GLE400 configuration uses the same primary tire size. Checking the exact sub-model still matters so the wheel diameter and current vehicle setup stay aligned with the tire you choose.

Frequently Asked Questions
These FAQs focus on 2017 Mercedes-Benz Trucks GLE400 tire size, 20-inch rim fitment, choosing the right 265/45R20 radial tire, and the practical checks that matter before putting the vehicle back on the road.
Tire Size & Fitment
What tire size fits a 2017 Mercedes-Benz Trucks GLE400?
The 2017 Mercedes-Benz Trucks GLE400 uses a 265/45R20 radial tire. That size is the primary fitment for the covered application and pairs with a 20-inch wheel.
That means the first step is not choosing between multiple factory sizes, but confirming that the vehicle still has its correct 20-inch wheels and has not been altered with different wheels or suspension changes. A replacement tire should also be checked against the existing wheel width, clearance at full steering lock, and the overall condition of the wheels before installation.
What size rim does a 2017 Mercedes-Benz Trucks GLE400 use?
The 2017 Mercedes-Benz Trucks GLE400 uses a 20-inch rim with its 265/45R20 tire fitment. The tire size itself confirms the wheel diameter through the final number in the size code.
Rim diameter is only part of the fitment picture, so it is worth confirming the actual wheel on the vehicle before replacing tires. A GLE400 that has been fitted with aftermarket wheels may still be 20 inches in diameter but differ in width or offset, which can affect how a replacement tire sits and clears the suspension or fenders.
Does the 2017 Mercedes-Benz Trucks GLE400 4Matic use the same tire size?
Yes. The covered 2017 Mercedes-Benz Trucks GLE400 4Matic application uses the same 265/45R20 radial tire size. That keeps fitment simple at the sub-model level.
Even with shared size fitment, it is still smart to inspect what is actually on the vehicle today. Wheel changes, plus-size conversions, or previous owner modifications can leave the SUV wearing a different setup than expected. Matching the replacement tire to the current wheel diameter and verifying clearance is especially important on a modern SUV with tight packaging around brakes and suspension components.
Choosing the Right Tire
What should I consider when choosing a 265/45R20 tire for a 2017 Mercedes-Benz Trucks GLE400?
Start with the correct size: 265/45R20 on a 20-inch wheel. Since this is a radial application, the main selection factors are keeping the proper size format and choosing a tire that suits how the GLE400 is driven, whether that is regular road use, occasional highway travel, or lower-mileage ownership.
It also helps to compare the replacement tire's dimensions with what is already on the vehicle, especially if the SUV has aftermarket wheels or suspension changes. Sidewall shape, wheel-width compatibility, and overall clearance can all influence the final result. A careful match helps preserve the balanced look and road behavior expected from this Mercedes-Benz fitment.
How do I choose between the available 265/45R20 tires for a 2017 Mercedes-Benz Trucks GLE400?
The best way to narrow the choice is to stay with the 265/45R20 size and compare tires by intended use, wheel compatibility, and how closely they match the vehicle's existing setup. On a GLE400, that often means prioritizing a tire that supports stable road manners and proper fit on the 20-inch wheel.
Looking beyond the size code is important because two tires in the same nominal size can still differ in profile shape and fitment behavior. Owners should inspect current wheel dimensions, note any suspension modifications, and make sure there is no rubbing at steering lock or during suspension travel. That practical check matters more than choosing by size code alone.
What rim-fitment details should I compare when choosing tires for a 2017 Mercedes-Benz Trucks GLE400?
Wheel diameter is the first detail, and the 2017 Mercedes-Benz Trucks GLE400 uses a 20-inch rim with its 265/45R20 tire. Beyond that, wheel width and offset deserve attention because they influence how the tire sits on the wheel and how much room remains around suspension and bodywork.
A replacement tire can only perform as intended if it is matched to the actual wheel on the vehicle. Measuring or confirming the current wheel setup is especially useful if the SUV was purchased used or has custom wheels. Small fitment differences can affect sidewall shape, steering clearance, and the visual stance of the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz Trucks GLE400?
Yes. A 2017 Mercedes-Benz Trucks GLE400 may use the correct 265/45R20 tire size on paper, but wheel changes, altered offset, suspension lowering, or other modifications can change how that tire fits on the vehicle. Even when the nominal size stays the same, the available clearance can be different.
A careful inspection should include wheel width, wheel position within the fender, and clearance at full steering lock and normal suspension movement. That is especially important on a modern SUV where brake components and inner liners can sit close to the tire. Confirming those details before replacement helps avoid rubbing, uneven wear, and fitment surprises.
What should I inspect before driving a 2017 Mercedes-Benz Trucks GLE400 on new tires?
Before road use, inspect the wheels for damage, verify the tire size is 265/45R20, and make sure each tire is seated and inflated properly. It is also wise to look over suspension and steering components, since worn parts can affect how a new tire behaves once the vehicle is back in service.
A short low-speed check drive can reveal rubbing, vibration, or pull that may not be obvious while the vehicle is parked. Owners should also recheck tire pressure after installation and continue monitoring for uneven wear or air loss during the first several drives. Those basic checks help confirm that the new tire and wheel combination is working as intended.
How often should tires on a 2017 Mercedes-Benz Trucks GLE400 be inspected?
Tires on a 2017 Mercedes-Benz Trucks GLE400 should be inspected regularly, not only when tread looks low. Routine checks should include pressure, tread wear, cuts, bulges, sidewall damage, and any signs of uneven wear that could point to alignment or suspension issues.
Vehicles that see less frequent use still deserve inspection because age, storage conditions, and long periods of sitting can affect tire condition. Looking over the tires before longer trips is especially worthwhile on an SUV like the GLE400, where tire condition plays a major role in ride quality and road stability. Regular inspection helps catch small issues before they become larger problems.
