The 2019 Mercedes-Benz Trucks GLE63 AMG blends modern AMG performance with the commanding stance and utility expected from a high-powered luxury sport utility vehicle. On a vehicle like this, tire selection is closely tied to its aggressive factory-style staggered setup and the wheel diameter already on the truck. The 2019 Mercedes-Benz Trucks GLE63 AMG uses radial tires in two sizes, 265/45R20 and 295/35R21, so the first step is confirming which wheel position and rim diameter you are matching. From there, the real decision centers on maintaining the correct size relationship, preserving the intended appearance, and checking fitment carefully if the truck has been modified.
Which Tire Size Is Right for The 2019 Mercedes-Benz Trucks GLE63 AMG
The 2019 Mercedes-Benz Trucks GLE63 AMG uses two primary tire sizes, both in radial construction, and they are tied to different wheel diameters. Because this fitment spans 20-inch and 21-inch rims, confirming the actual wheel diameter and position on the vehicle comes before choosing a tire. The key decision is matching the correct size to the existing wheel setup rather than treating these two sizes as interchangeable alternatives.
265/45R20 is a metric radial size in which 265 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2019 Mercedes-Benz Trucks GLE63 AMG, this size is part of the vehicle's modern performance-oriented fitment rather than a vintage sizing system. Its dimensions keep it closely aligned with the vehicle's larger-diameter wheel package while maintaining the intended tire profile. Use this size only when it matches the wheel already on the truck and the position being replaced.
295/35R21 is a metric radial size where 295 indicates nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 21 is the wheel diameter in inches. For the 2019 Mercedes-Benz Trucks GLE63 AMG, this is the wider, lower-profile of the two primary sizes and belongs to the 21-inch wheel fitment. The size reflects a modern high-performance tire profile with substantial width and a short sidewall. It should be selected only when the truck is equipped with the corresponding 21-inch wheel and the correct wheel position is being matched.
The covered sub-model uses the same two-size radial fitment, so the main fitment question is not trim variation but wheel setup. Checking the truck's actual wheel diameters and tire positions matters because this application uses both 20-inch and 21-inch sizes.

Frequently Asked Questions
For the 2019 Mercedes-Benz Trucks GLE63 AMG, the most important questions center on its two-size radial fitment, 20-inch versus 21-inch wheel matching, tire selection, and the checks worth making before regular road use or replacement.
Tire Size & Fitment
What tire size fits a 2019 Mercedes-Benz Trucks GLE63 AMG?
The 2019 Mercedes-Benz Trucks GLE63 AMG uses two primary radial tire sizes: 265/45R20 and 295/35R21. These are not simply two optional versions of the same fitment, because they correspond to different wheel diameters and a staggered-style setup on the vehicle.
The practical next step is to confirm which wheel and position you are replacing before choosing a tire. Matching the existing wheel diameter is essential, and the truck should also be checked for any aftermarket wheel, suspension, or alignment changes that could affect proper size selection.
What size rim does a 2019 Mercedes-Benz Trucks GLE63 AMG use?
A 2019 Mercedes-Benz Trucks GLE63 AMG uses both 20-inch and 21-inch rim diameters, tied to its two primary tire sizes. The 265/45R20 mounts on a 20-inch rim, while the 295/35R21 mounts on a 21-inch rim.
That makes wheel verification especially important before ordering replacement tires. Looking only at the vehicle name is not enough when two rim diameters are used on the same application, so the actual wheel on the truck should be checked along with the tire already mounted to it.
Do all 2019 Mercedes-Benz Trucks GLE63 AMG sub-models use the same tire size?
The covered 2019 Mercedes-Benz Trucks GLE63 AMG 4Matic sub-model uses the same two-size radial fitment for this application. Those sizes are 265/45R20 and 295/35R21, so the sub-model itself does not introduce a separate tire-size pattern here.
Even with shared sub-model fitment, the important detail is still wheel position and rim diameter. A replacement decision should start by checking the size printed on the current tire and confirming whether the truck remains on its original wheel setup or has been changed since new.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Mercedes-Benz Trucks GLE63 AMG?
Start with the exact size already required for the wheel on the truck: 265/45R20 or 295/35R21. Both are modern metric radial sizes, so the key is not choosing between bias-ply and radial construction, but matching the correct size, wheel diameter, and intended position.
From there, compare the tire's dimensions against the wheel setup already in place and make sure the replacement keeps the truck's fitment balanced. It also helps to inspect for altered ride height, non-original wheels, or clearance changes that could make an otherwise correct size less straightforward.
How do I choose between the available 265/45R20 and 295/35R21 tires for a 2019 Mercedes-Benz Trucks GLE63 AMG?
These two sizes are chosen by application on the vehicle, not by personal preference between profiles. The 265/45R20 belongs with a 20-inch wheel, while the 295/35R21 belongs with a 21-inch wheel, so the correct choice depends on the wheel diameter and mounting position being matched.
A good replacement strategy is to compare the new tire with the existing setup on the truck rather than assume both sizes can be used anywhere. Checking side-to-side consistency on the same axle and confirming the wheel itself before mounting helps avoid fitment mistakes and uneven appearance.
What rim-width specifications should I compare when choosing 2019 Mercedes-Benz Trucks GLE63 AMG tires?
Rim width matters because a tire's intended profile depends on the wheel supporting it correctly. On a 2019 Mercedes-Benz Trucks GLE63 AMG, that consideration is especially important because the fitment already combines substantial section width with two different rim diameters.
The safest approach is to compare the new tire against the wheel currently on the truck and confirm that the wheel width suits the size being replaced. That becomes even more important if the vehicle has custom wheels, spacers, or previous tire changes that may have altered the original setup.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Mercedes-Benz Trucks GLE63 AMG restoration?
Yes. Even on a newer performance SUV, correct tire fitment plays a major role in how authentic and well-sorted the vehicle looks. The 2019 Mercedes-Benz Trucks GLE63 AMG uses a two-size radial setup, so preserving the intended relationship between the 20-inch and 21-inch fitments helps maintain its visual balance.
A restoration-minded replacement should begin with the exact size already associated with each wheel rather than treating the setup as generic SUV fitment. Owners who want a highly accurate presentation should also compare their current wheels and tire markings against vehicle-specific reference material before making appearance-driven changes.
How does tire construction affect the appearance of a restored 2019 Mercedes-Benz Trucks GLE63 AMG?
On the 2019 Mercedes-Benz Trucks GLE63 AMG, appearance is shaped more by maintaining the proper modern radial sizing and wheel pairing than by choosing between construction types. Both primary sizes for this application are radial, which suits the vehicle's contemporary high-performance character and low-profile stance.
For a restoration-oriented owner, the visual goal is usually keeping the correct proportions at each corner and avoiding substitute sizes that change the truck's overall presentation. Wheel diameter, sidewall height, and tire width all influence that result, so the existing setup should be confirmed carefully before replacement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mercedes-Benz Trucks GLE63 AMG?
Yes. Wheel changes, altered ride height, suspension work, spacers, or body modifications can all affect how 265/45R20 and 295/35R21 tires sit on a 2019 Mercedes-Benz Trucks GLE63 AMG. Even when the tire size itself is correct, a changed vehicle setup can alter clearance and overall compatibility.
That is why replacement should begin with the truck as it sits today, not just the original vehicle application. Looking at current wheel dimensions, checking steering and suspension clearance, and confirming there is no rubbing under load or lock-to-lock movement helps prevent expensive fitment mistakes.
What should I inspect before driving a 2019 Mercedes-Benz Trucks GLE63 AMG on new tires?
Before road use, inspect inflation pressure, tread seating, valve condition, and visible sidewall condition on each tire. On a 2019 Mercedes-Benz Trucks GLE63 AMG, it also makes sense to confirm that the 20-inch and 21-inch tires are mounted in the correct positions and that no wheel damage is present.
A short initial check drive should include listening for rubbing, vibration, or pull that could point to fitment or wheel issues. Rechecking pressure after installation and making sure the suspension, alignment, and brake components are in sound condition helps the new tires perform as intended.
How often should tires on a 2019 Mercedes-Benz Trucks GLE63 AMG be inspected?
Tires on a 2019 Mercedes-Benz Trucks GLE63 AMG should be inspected regularly, not only when tread looks worn. A visual check for uneven wear, cuts, bulges, cracking, and air loss is worthwhile before longer drives and as part of normal maintenance because performance-oriented fitments can be sensitive to setup changes.
Regular inspection is also a good time to confirm that the front-to-rear size relationship remains correct and that wheel damage or alignment issues have not developed. Trucks that are driven infrequently still need attention, since age, storage conditions, and low use can affect tire condition over time.
