The 2019 Mercedes-Benz Trucks GLE43 AMG sits at the point where luxury SUV comfort meets AMG-tuned performance, and tire fitment is a major part of how that balance comes together. On this model, the first step is identifying the exact 4Matic or Coupe front and rear setup, because the GLE43 AMG uses several different modern metric radial sizes across 20-inch, 21-inch, and 22-inch wheels. That means the real choice is not simply picking a tire, but matching the correct size to the wheel position and vehicle configuration. Owners replacing worn tires should pay close attention to staggered fitment, wheel diameter, and overall proportions before changing sizes.
Which Tire Size Is Right for The 2019 Mercedes-Benz Trucks GLE43 AMG
The 2019 Mercedes-Benz Trucks GLE43 AMG uses six primary tire sizes, and the right one depends on whether the vehicle is a 4Matic model or a Coupe with separate front and rear fitments. Wheel diameter is the first thing to confirm, since this application spans 20-inch, 21-inch, and 22-inch rims, and staggered Coupe setups require the correct tire at each axle position.
265/40R21 is a modern metric radial size that uses a 265-millimeter section width, a 40-series aspect ratio, radial construction, and a 21-inch rim diameter. On the 2019 Mercedes-Benz Trucks GLE43 AMG, this size belongs to a contemporary performance-oriented fitment where wheel diameter and profile are both central to the vehicle's handling character. Its dimensions place it close to other GLE43 AMG options in overall height, but it remains a distinct fitment rather than a general substitute. This size should be selected only after confirming the exact wheel package currently on the vehicle.
265/45R20 is a metric radial tire size with a 265-millimeter section width, a 45-series profile, and fitment on a 20-inch wheel. For the 2019 Mercedes-Benz Trucks GLE43 AMG, it represents one of the standard modern radial sizes used on the 4Matic configuration rather than the Coupe staggered setup. The slightly taller sidewall compared with a 40-series size changes the visual balance and should be matched to the correct wheel diameter. This is the right size to evaluate when the vehicle is equipped with the 20-inch wheel package and a non-staggered fitment.
275/45R21 is a modern metric radial size that combines a 275-millimeter section width, a 45-series profile, and a 21-inch rim diameter. On the 2019 Mercedes-Benz Trucks GLE43 AMG, this size serves as a front fitment for the 4Matic Coupe, so it should be treated as part of a matched staggered arrangement rather than a stand-alone all-around size. Its role is tied to proper front-axle balance with the corresponding rear tire choice. Buyers should confirm that the vehicle is a Coupe and that the front wheels are 21-inch before selecting this fitment.
285/40R22 is a metric radial tire size with a 285-millimeter section width, a 40-series aspect ratio, and a 22-inch wheel diameter. For the 2019 Mercedes-Benz Trucks GLE43 AMG Coupe, this is a front tire size used with a staggered setup, making position-specific fitment especially important. The larger rim diameter gives it a different wheel-and-tire presentation from the 21-inch Coupe front alternative, even though overall height stays in a similar range. This size belongs on vehicles already equipped with the 22-inch front wheel package, not as a general replacement for every GLE43 AMG.
315/40R21 is a wide modern metric radial that uses a 315-millimeter section width, a 40-series profile, and a 21-inch rim. On the 2019 Mercedes-Benz Trucks GLE43 AMG Coupe, it functions as a rear tire size, pairing with a narrower front fitment to create the vehicle's staggered layout. The substantial section width makes wheel position and clearance more critical than with the standard 4Matic fitments. This size should be chosen only for the correct rear application on a Coupe that is already set up for the 21-inch staggered combination.
325/35R22 is a very wide metric radial size with a 325-millimeter section width, a 35-series profile, and a 22-inch rim diameter. For the 2019 Mercedes-Benz Trucks GLE43 AMG Coupe, this is a rear fitment used with the larger 22-inch staggered arrangement, so it is tied to both axle position and wheel package. Its low-profile construction and width make precise wheel matching especially important on a performance SUV application. This is the size to evaluate when confirming a 22-inch Coupe rear setup rather than a square or interchangeable fitment.
Sub-model fitment matters on the 2019 Mercedes-Benz Trucks GLE43 AMG because tire sizing changes with the body configuration and wheel package. The standard 4Matic uses one of two same-size setups, while the Coupe uses staggered front and rear sizes that must be matched to the correct axle.

2019 Mercedes-Benz Trucks GLE43 AMG 4Matic
The 2019 Mercedes-Benz Trucks GLE43 AMG 4Matic uses either a 265/45R20 or 265/40R21 radial fitment, depending on the wheel package installed on the vehicle. Tire selection starts with confirming whether the SUV is on 20-inch or 21-inch wheels, then matching the replacement tire to that setup.
2019 Mercedes-Benz Trucks GLE43 AMG 4Matic Coupe Front
The 2019 Mercedes-Benz Trucks GLE43 AMG 4Matic Coupe Front uses a dedicated front tire size, either 275/45R21 or 285/40R22 radial. That front-specific fitment should be chosen only after confirming the Coupe wheel package, since the rear axle uses a different size.
2019 Mercedes-Benz Trucks GLE43 AMG 4Matic Coupe Rear
The 2019 Mercedes-Benz Trucks GLE43 AMG 4Matic Coupe Rear uses a wider rear tire, either 315/40R21 or 325/35R22 radial, as part of a staggered setup. Rear tire replacement should be handled with the matching front size and wheel diameter in mind so the Coupe keeps its intended stance and fitment balance.
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:

Frequently Asked Questions
Common tire questions for the 2019 Mercedes-Benz Trucks GLE43 AMG usually come down to identifying the exact wheel package, understanding staggered Coupe fitment, and confirming the correct size for the front or rear axle before replacing tires.
Tire Size & Fitment
What tire size fits a 2019 Mercedes-Benz Trucks GLE43 AMG?
The 2019 Mercedes-Benz Trucks GLE43 AMG uses several tire sizes: 265/45R20, 265/40R21, 275/45R21, 285/40R22, 315/40R21, and 325/35R22. The standard 4Matic model uses either 265/45R20 or 265/40R21, while the Coupe uses staggered front and rear sizes, with 275/45R21 and 315/40R21 on one setup or 285/40R22 and 325/35R22 on another.
That makes identification more important than on a single-size application. The first step is confirming whether the vehicle is a standard 4Matic or a Coupe, then checking the wheel diameter and whether the tires are the same size front to rear or staggered by axle.
What size rim does a 2019 Mercedes-Benz Trucks GLE43 AMG use?
A 2019 Mercedes-Benz Trucks GLE43 AMG uses 20-inch, 21-inch, or 22-inch rims depending on the tire size and configuration. The 265/45R20 fitment uses a 20-inch rim, the 265/40R21, 275/45R21, and 315/40R21 sizes use 21-inch rims, and the 285/40R22 and 325/35R22 sizes use 22-inch rims.
Rim diameter should be confirmed before any tire purchase because these sizes are not interchangeable across different wheels. On Coupe models, front and rear wheel diameters also need to stay matched to the correct staggered package so the replacement tires stay aligned with the existing setup.
Do all 2019 Mercedes-Benz Trucks GLE43 AMG sub-models use the same tire size?
No, the 2019 Mercedes-Benz Trucks GLE43 AMG does not use one tire size across every sub-model. The 4Matic model uses either 265/45R20 or 265/40R21, while the 4Matic Coupe uses front and rear staggered sizes, with either 275/45R21 front and 315/40R21 rear or 285/40R22 front and 325/35R22 rear.
That difference matters because a Coupe rear tire is not just a larger version of the standard SUV fitment. Buyers should verify the exact sub-model and wheel package already on the vehicle, especially when replacing only two tires or working with a staggered front-to-rear arrangement.
Choosing the Right Tire
What should I consider when choosing a 2019 Mercedes-Benz Trucks GLE43 AMG tire?
Start with the exact tire size already required by the vehicle, since the 2019 Mercedes-Benz Trucks GLE43 AMG uses multiple radial fitments across 20-inch, 21-inch, and 22-inch wheels. It is also important to confirm whether the vehicle is a standard 4Matic with same-size tires or a Coupe with dedicated front and rear sizes.
After that, compare the tire's intended wheel position, especially on staggered Coupe setups where front and rear sizes are different. Owners should also check the current wheel package and avoid assuming that a tire with a similar overall diameter belongs on the same rim or axle position.
How do I choose between the available radial sizes for a 2019 Mercedes-Benz Trucks GLE43 AMG?
The choice is determined by the vehicle's existing configuration rather than personal preference alone. A 2019 Mercedes-Benz Trucks GLE43 AMG 4Matic uses either a 265/45R20 or 265/40R21 fitment, while the Coupe uses one of two staggered combinations with different front and rear tire sizes.
Once the configuration is confirmed, the correct approach is to match the replacement tire to the wheel diameter and axle position already in use. That is especially important on Coupe models, where the wider rear tires are part of the intended fitment balance and should not be mixed casually with other sizes.
Why does the 2019 Mercedes-Benz Trucks GLE43 AMG have more than one tire size?
The 2019 Mercedes-Benz Trucks GLE43 AMG has more than one tire size because different versions of the vehicle use different wheel packages and, in Coupe form, a staggered front-and-rear arrangement. That creates separate fitments for 20-inch, 21-inch, and 22-inch wheels, along with narrower front and wider rear sizes on Coupe models.
This means tire replacement should follow the vehicle's actual setup rather than the broader model name alone. Checking the sub-model, axle position, and wheel diameter helps prevent ordering a standard 4Matic size for a Coupe or choosing a front tire size when the rear fitment is required.
Restoration & Appearance
Does correct tire fitment matter for the appearance of a 2019 Mercedes-Benz Trucks GLE43 AMG?
Yes, correct tire fitment has a strong effect on the appearance of a 2019 Mercedes-Benz Trucks GLE43 AMG. The different 20-inch, 21-inch, and 22-inch wheel packages change sidewall profile and visual proportion, and the Coupe's staggered setup also depends on the correct relationship between its front and rear tire widths.
Using the proper size helps preserve the intended stance instead of creating a mismatched look from axle to axle. Owners who care about visual presentation should confirm the vehicle's current wheel package and avoid mixing fitments that were designed for another GLE43 AMG configuration.
How does tire construction affect the appearance of a 2019 Mercedes-Benz Trucks GLE43 AMG?
On the 2019 Mercedes-Benz Trucks GLE43 AMG, the primary fitments are modern radial sizes, so the visual character comes more from profile, width, and wheel diameter than from choosing between bias-ply and radial construction. A 40-series or 35-series tire on a larger wheel gives the vehicle a different presentation than the 45-series options used on smaller rims.
That makes exact sizing especially important for owners who want to preserve the vehicle's intended look. Matching the correct front and rear dimensions on Coupe models is just as important visually as it is mechanically, since the wider rear fitment is part of the overall design balance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mercedes-Benz Trucks GLE43 AMG?
Yes, modifications can affect tire fitment on a 2019 Mercedes-Benz Trucks GLE43 AMG even when the replacement tire matches one of the original size formats. Changes such as aftermarket wheels, altered offsets, suspension lowering, or body modifications can change the available space around the tire and alter how a staggered setup sits on the vehicle.
A modified vehicle should be checked for wheel diameter, width, and clearance at both steering lock and normal ride height before a new tire is selected. That step is especially important on Coupe models using the wider rear sizes, where small setup differences can matter more.
What should I inspect before driving a 2019 Mercedes-Benz Trucks GLE43 AMG on new tires?
Before driving a 2019 Mercedes-Benz Trucks GLE43 AMG on new tires, inspect wheel condition, verify that each tire matches the correct axle position, and confirm that front and rear sizes are not mixed incorrectly on a staggered Coupe setup. It is also wise to check inflation, valve condition, and basic visual signs such as cuts, bulges, or damage from mounting.
A short road check should include listening for rubbing and confirming normal steering feel. Vehicles that have seen wheel changes or suspension work deserve extra attention, since even a correct nominal tire size can create issues if the surrounding setup has been altered.
What should I check before a longer drive in a 2019 Mercedes-Benz Trucks GLE43 AMG?
Before a longer drive, make sure the 2019 Mercedes-Benz Trucks GLE43 AMG has the correct tire size at each corner, especially if it is a Coupe with staggered front and rear fitment. Tire pressure, tread condition, visible sidewall aging, and any signs of slow air loss should all be checked before putting sustained miles on the vehicle.
Longer trips also make it worthwhile to inspect wheel hardware and look closely at inner and outer sidewall clearance. On vehicles with 21-inch or 22-inch wheel packages, confirming that the tires remain free of rub marks or impact damage helps reduce surprises once the drive is underway.
