The 2022 Mercedes-Benz EQS AMG brings high-performance electric luxury into a full-size sedan format, blending AMG character with the smooth, quiet presence expected from the EQS line. On a vehicle this advanced, tire fitment matters not just for appearance, but for maintaining the intended balance of handling, ride quality, and wheel compatibility. The 2022 Mercedes-Benz EQS AMG uses radial tires in two fitments, 275/40R21 and 275/35R22, tied to different wheel diameters. That makes wheel confirmation the first step before comparing tire choices. Once the wheel size is verified, the real decision is choosing the correct metric radial fitment for the car’s exact setup and intended road use.
Which Tire Size Is Right for The 2022 Mercedes-Benz EQS AMG
The 2022 Mercedes-Benz EQS AMG uses two primary tire sizes, and the key difference is wheel diameter: 21-inch wheels use 275/40R21, while 22-inch wheels use 275/35R22. Since both sizes appear on the EQS AMG 4Matic, the first step is confirming which wheels are actually on the car before selecting a replacement tire.
A 275/35R22 tire is a metric radial size with a 275-millimeter section width, a 35-series aspect ratio, and a fitment for a 22-inch wheel. On the 2022 Mercedes-Benz EQS AMG, this is one of the two primary radial fitments and is tied specifically to the larger wheel diameter option. Its lower-profile format makes wheel verification especially important, since a 22-inch tire cannot be used on a 21-inch wheel. This size is the right path only when the car is already equipped with 22-inch wheels and the owner wants to preserve that wheel-and-tire setup.
A 275/40R21 tire is a metric radial size that uses a 275-millimeter section width, a 40-series aspect ratio, and a 21-inch wheel diameter. For the 2022 Mercedes-Benz EQS AMG, it serves as the alternate primary fitment to the 22-inch package, so it is not interchangeable with the larger-rim size without changing wheels. The section width stays the same as the 22-inch fitment, but the tire is built around a different rim diameter. This size should be chosen only after confirming that the car is fitted with 21-inch wheels rather than the 22-inch setup.
The covered sub-model fitment is straightforward, but it still requires a wheel check because the same EQS AMG 4Matic can use two different tire sizes. Identifying the exact wheel diameter on the car is what determines the correct replacement size.

Frequently Asked Questions
Owners of a 2022 Mercedes-Benz EQS AMG usually need clarity on the two tire sizes, 21-inch versus 22-inch wheel fitment, and what to inspect before replacing tires on a high-performance electric luxury sedan.
Tire Size & Fitment
What tire size fits a 2022 Mercedes-Benz EQS AMG?
The 2022 Mercedes-Benz EQS AMG uses two primary tire sizes: 275/40R21 and 275/35R22. Both are radial metric sizes, and both are used on the EQS AMG 4Matic, with the correct choice determined by the wheel diameter on the car.
That means the main fitment question is not which size seems close, but which wheel package is actually installed. A 21-inch wheel requires 275/40R21, while a 22-inch wheel requires 275/35R22. Checking the current tire sidewall and confirming the wheel diameter before purchase helps avoid ordering a tire that matches the car model but not the actual wheel setup.
What size rim does a 2022 Mercedes-Benz EQS AMG use?
A 2022 Mercedes-Benz EQS AMG uses either a 21-inch or 22-inch rim, depending on the wheel package on the vehicle. The 275/40R21 tire fits a 21-inch rim, and the 275/35R22 tire fits a 22-inch rim.
Rim diameter is the first thing to verify because these two tire sizes are tied to different wheels, not just different profiles. Even though both tires share the same 275-millimeter section width, the wheel diameter changes the fitment completely. Reading the full tire size already mounted on the car is usually the fastest way to confirm whether the EQS AMG is on the 21-inch or 22-inch setup.
Why does the 2022 Mercedes-Benz EQS AMG have more than one tire size?
The 2022 Mercedes-Benz EQS AMG has more than one tire size because it was fitted with different wheel diameters. The two primary fitments are 275/40R21 for 21-inch wheels and 275/35R22 for 22-inch wheels, both used on the EQS AMG 4Matic.
This is a wheel-package difference rather than a case of one size replacing the other. The tire widths remain the same, but the aspect ratio and rim diameter change with the wheel choice. For an owner, that means the correct replacement tire depends on the exact wheel currently on the car, especially if the vehicle has been changed from its original wheel package at some point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Mercedes-Benz EQS AMG?
Start with the correct primary size for the wheel package already on the car: 275/40R21 for 21-inch wheels or 275/35R22 for 22-inch wheels. Since both sizes are radial metric fitments for the 2022 Mercedes-Benz EQS AMG, the first decision is wheel diameter, not brand preference or appearance.
After that, compare the tire’s suitability for the vehicle’s use, including wheel compatibility, road conditions, and whether the car remains in its original wheel-and-suspension configuration. On a modern AMG EV sedan, staying with the proper size matters for preserving intended clearance and overall fitment. Any aftermarket wheel or suspension change should be checked carefully before ordering replacement tires.
How do I choose between the available 2022 Mercedes-Benz EQS AMG tire sizes?
You do not choose between 275/40R21 and 275/35R22 based on preference alone, because each size belongs to a specific wheel diameter. The 21-inch fitment uses 275/40R21, and the 22-inch fitment uses 275/35R22, so the correct tire follows the wheel already on the car.
The practical step is to inspect the wheel and read the existing tire sidewall before replacing anything. Both sizes are close in overall diameter, but they are not mounted on the same rim size. That means a buyer should treat them as separate fitments for separate wheel packages, especially if the vehicle was delivered with optional wheels or later modified by a previous owner.
How do I choose between the available radial tires for a 2022 Mercedes-Benz EQS AMG?
Choosing a radial tire for a 2022 Mercedes-Benz EQS AMG begins with selecting the exact factory-style size that matches the wheel diameter on the car. For this model, that means 275/40R21 on 21-inch wheels or 275/35R22 on 22-inch wheels, with both sizes using modern metric radial construction.
Once the size is confirmed, compare tires by how well they suit the car’s intended use and by whether the vehicle still has its original wheel setup. A larger mistake on this model is using the wrong rim diameter, not choosing between two similar-looking tires. Careful confirmation matters even more if the car has aftermarket wheels, alignment changes, or altered ride height.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Mercedes-Benz EQS AMG restoration or preservation project?
Yes, correct tire fitment still matters on a 2022 Mercedes-Benz EQS AMG, even though it is far newer than a traditional collector car. The correct size preserves the relationship between the wheel package and the tire profile, which is a major part of how this modern AMG electric sedan presents itself visually and functions on the road.
For a preservation-minded owner, the important point is matching the tire to the wheel package actually associated with the car rather than treating the two sizes as interchangeable. Keeping the correct 21-inch or 22-inch fitment helps maintain the intended stance and avoids obvious mismatch issues. Any appearance-focused project should begin with wheel confirmation before tire replacement.
How does tire size affect the appearance of a 2022 Mercedes-Benz EQS AMG?
Tire size has a visible effect on a 2022 Mercedes-Benz EQS AMG because the model uses two different wheel-and-profile combinations: 275/40R21 and 275/35R22. Both keep the same nominal width, but the sidewall proportion changes with the wheel diameter, altering the visual balance between tire and rim.
That matters for owners who want to preserve the car’s intended presentation rather than simply replace worn tires. A 21-inch setup should stay with 275/40R21, and a 22-inch setup should stay with 275/35R22 unless a broader wheel-and-tire change is being planned. Appearance and fitment go together closely on this kind of modern performance luxury vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Mercedes-Benz EQS AMG?
Yes, modifications can affect tire fitment on a 2022 Mercedes-Benz EQS AMG. If the car has aftermarket wheels, altered suspension height, alignment changes, or body modifications, the original 275/40R21 or 275/35R22 fitment may no longer tell the whole story about clearance and wheel compatibility.
That is why modified cars should be checked at the wheel, not just by model name. Confirm the actual rim diameter first, then inspect width, inner clearance, outer fender clearance, and steering travel before replacing tires. A modern high-performance EV places tight demands on wheel-and-tire packaging, so even small setup changes can matter during tire selection.
What should I inspect before driving a 2022 Mercedes-Benz EQS AMG on new tires?
Before driving a 2022 Mercedes-Benz EQS AMG on new tires, inspect that the installed size matches the wheel diameter, the tires are seated properly, and inflation is set correctly for the application. A quick visual check for sidewall damage, bead issues, and any immediate clearance concern is also worthwhile.
Road-testing should begin with attention to vibration, rubbing, and steering behavior, especially if the car has recently had wheel service or any non-stock changes. It also helps to recheck pressure after initial use and confirm that no slow air loss is present. On a vehicle with two valid rim diameters, verifying the correct size at installation is especially important.
What should I check before a longer drive in a 2022 Mercedes-Benz EQS AMG?
Before a longer drive, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. On a 2022 Mercedes-Benz EQS AMG, it also makes sense to confirm that the car is riding on the correct size for its wheel package, either 275/40R21 or 275/35R22.
A longer trip puts more importance on catching issues that may not show up around town, such as a slow air leak or a slight clearance problem after recent service. Wheel fastener torque, alignment condition, and visible signs of uneven wear are also worth reviewing. Any vibration or rubbing should be resolved before the car is driven at sustained highway speeds.
