The 2025 Mercedes-Benz EQS AMG brings high-performance EV engineering into a full-size luxury sedan format, pairing AMG character with the quiet, instant response that defines the EQS lineup. Buyers looking at this exact model are usually balancing appearance, wheel package, and road-use expectations just as much as brand preference. This EQS AMG uses radial tires in two fitments, 275/40R21 and 275/35R22, so the first step is confirming which wheel diameter is on the car. Because both sizes share the same section width but differ by rim diameter and profile, the real decision centers on matching the installed wheel setup and preserving proper clearance and overall stance.
Which Tire Size Is Right for The 2025 Mercedes-Benz EQS AMG
The 2025 Mercedes-Benz EQS AMG uses two primary tire sizes, and the correct choice depends first on wheel diameter. One fitment is built around a 21-inch rim and the other around a 22-inch rim, so identifying the wheels already on the car is more important than comparing the size codes in the abstract. Once that is confirmed, the decision becomes selecting the right radial tire within that exact fitment and making sure the vehicle has not been altered in a way that affects clearance.
A 275/35R22 tire uses a 275-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 22-inch rim. On the 2025 Mercedes-Benz EQS AMG, this fitment reflects a very low-profile modern radial setup paired with the larger wheel diameter used on some configurations. The short sidewall gives this size a distinct visual character compared with the 21-inch alternative while staying within a very similar overall diameter range. Choosing this size starts with confirming that the car is equipped with 22-inch wheels and checking that any suspension or wheel changes have not altered available clearance.
A 275/40R21 tire carries the same 275-millimeter nominal section width, but its 40-series profile is matched to a 21-inch rim rather than a 22-inch wheel. For the 2025 Mercedes-Benz EQS AMG, this is the alternate primary radial fitment and keeps the vehicle in a similar overall tire height range with a different wheel-and-sidewall relationship. That makes it important to treat the size as a wheel-specific fitment rather than a cosmetic variation. Buyers considering this size should verify that the car is actually on 21-inch wheels before comparing tire options for road use, appearance, and ride character.
Sub-model fitment is straightforward here because the covered EQS AMG configuration uses the same two primary radial tire sizes. The key is not trim hierarchy, but confirming whether the car is riding on 21-inch or 22-inch wheels before selecting a tire.

Frequently Asked Questions
Common questions for the 2025 Mercedes-Benz EQS AMG usually center on its two tire sizes, 21-inch versus 22-inch wheel fitment, and what owners should check before replacing tires on a high-performance luxury EV.
Tire Size & Fitment
What tire size fits a 2025 Mercedes-Benz EQS AMG?
The 2025 Mercedes-Benz EQS AMG uses two primary tire sizes: 275/40R21 and 275/35R22. Both are radial metric sizes with the same nominal section width, but they are built for different wheel diameters and different sidewall profiles.
The correct choice depends on the wheels actually installed on the car. A 21-inch wheel requires the 275/40R21 fitment, while a 22-inch wheel requires 275/35R22. Since these sizes are tied to different rim diameters, selection should start with wheel confirmation rather than assuming either size can be used interchangeably.
What size rim does a 2025 Mercedes-Benz EQS AMG use?
A 2025 Mercedes-Benz EQS AMG uses either a 21-inch or 22-inch rim, depending on the tire fitment on the vehicle. The 275/40R21 size matches a 21-inch rim, and the 275/35R22 size matches a 22-inch rim.
That makes rim diameter the first thing to verify before ordering replacement tires. Reading the current tire sidewall is usually the quickest check, but the wheel itself should also be inspected if there is any doubt. Cars with aftermarket wheels or previous tire changes deserve an extra clearance and fitment check before replacement.
Why does the 2025 Mercedes-Benz EQS AMG have more than one tire size?
The 2025 Mercedes-Benz EQS AMG has more than one tire size because it can be equipped with different wheel diameters. One setup uses 275/40R21 on a 21-inch rim, while the other uses 275/35R22 on a 22-inch rim.
Those two sizes keep the tire in a similar overall height range while changing the wheel-to-sidewall relationship. That is why the sizes should be treated as wheel-package-specific fitments rather than simple alternatives. The practical next step is to confirm which wheel package is on the car and then match the tire size to that setup.
Choosing the Right Tire
What should I consider when choosing a 275/40R21 tire for a 2025 Mercedes-Benz EQS AMG?
A 275/40R21 tire for the 2025 Mercedes-Benz EQS AMG needs to match the car's 21-inch wheel setup exactly. The main considerations are correct size, radial construction, and whether the vehicle still has its intended wheel and suspension configuration.
Beyond basic fitment, look at how the car is actually used and inspect the current setup for signs of rubbing, uneven wear, or previous modifications. A high-performance luxury EV places real demands on tire condition, so replacement should also include a careful check of wheel condition, alignment behavior, and inflation maintenance rather than focusing on size code alone.
What should I consider when choosing a 275/35R22 tire for a 2025 Mercedes-Benz EQS AMG?
Choosing a 275/35R22 tire for a 2025 Mercedes-Benz EQS AMG starts with confirming that the car is equipped with 22-inch wheels. This size uses the same nominal width as the 21-inch fitment, but its lower-profile sidewall makes it a distinct wheel-specific choice.
That means the buyer should focus on exact size matching, wheel condition, and real-world clearance around suspension and bodywork. Extra attention is worthwhile if the car has been lowered, fitted with non-original wheels, or previously aligned around a different setup. On a vehicle like the EQS AMG, even small fitment deviations are worth catching before road use.
How do I choose between the available tire sizes for a 2025 Mercedes-Benz EQS AMG?
The 2025 Mercedes-Benz EQS AMG does not ask the owner to choose freely between 275/40R21 and 275/35R22 in the same way two optional replacement styles might. The correct size is determined by whether the car is on a 21-inch or 22-inch wheel package.
Once the wheel diameter is confirmed, the buying decision becomes much simpler: stay with the matching tire size and evaluate the tire itself rather than the alternate fitment. If the car was purchased used or has been modified, checking the actual wheel dimensions and current sidewall markings is the safest way to avoid ordering the wrong size.
Restoration & Appearance
Does correct tire fitment matter for a 2025 Mercedes-Benz EQS AMG restoration or preservation project?
Correct tire fitment matters on a 2025 Mercedes-Benz EQS AMG even in an early preservation-oriented project, because the car's appearance and stance are closely tied to its wheel-and-tire package. The two approved sizes, 275/40R21 and 275/35R22, create different visual proportions because they are matched to different rim diameters.
Keeping the proper size for the installed wheel helps preserve the intended relationship between sidewall height, wheel presentation, and body clearance. Owners focused on preserving an as-delivered look should confirm the actual wheel package on the car before replacement. That avoids introducing a tire size that changes the visual balance or raises fitment questions later.
How does tire profile affect the appearance of a 2025 Mercedes-Benz EQS AMG?
Tire profile has a clear effect on the appearance of a 2025 Mercedes-Benz EQS AMG because the two primary sizes use different sidewall heights. A 275/40R21 places more sidewall around a 21-inch wheel, while a 275/35R22 wraps a shorter sidewall around a larger 22-inch rim.
That difference changes how much wheel is visually emphasized without turning either size into a universal substitute for the other. Buyers who care about preserving the car's intended look should match the replacement tire to the wheel package already fitted. It is a styling decision rooted in correct fitment, not just a preference for one number over another.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Mercedes-Benz EQS AMG?
Yes, modifications can affect tire fitment on a 2025 Mercedes-Benz EQS AMG even when the tire size itself appears correct. Changes to wheel width, offset, ride height, alignment settings, or suspension components can alter fender clearance, steering clearance, and how the tire sits within the wheel opening.
That matters with either 275/40R21 or 275/35R22 because both are tied to specific wheel diameters and a performance-oriented chassis setup. A car with aftermarket wheels or lowered suspension deserves a careful measurement and visual inspection before replacement. Catching those changes early helps avoid rubbing, uneven wear, and ordering a tire for the wrong wheel specification.
What should I inspect before driving a 2025 Mercedes-Benz EQS AMG on new tires?
Before driving a 2025 Mercedes-Benz EQS AMG on new tires, inspect the wheel diameter, verify the tire size, and look over the wheels for damage or prior repair issues. Tire pressure should be set correctly, and the sidewalls and tread should be checked for any signs of shipping damage or mounting problems.
It is also wise to confirm that nothing contacts the tire at full steering lock or under suspension compression. A brief road test should be paired with a follow-up look for rubbing, vibration, or unusual wear patterns. On a heavy, high-performance EV, early attention to pressure, alignment feel, and clearance can prevent problems from developing quickly.
What should I check before a longer drive in a 2025 Mercedes-Benz EQS AMG?
Before a longer drive in a 2025 Mercedes-Benz EQS AMG, confirm that the tires match the installed wheel diameter and inspect them for proper inflation, cuts, bulges, cracking, and uneven tread wear. It is also smart to look at the wheels themselves for bends, curb damage, or anything that could affect sealing or balance.
Longer trips put more heat cycles and sustained load on the tire than short local use, so small issues become more important. Owners should also pay attention to any vibration, pull, or steering change that develops early in the drive. That kind of pre-trip inspection is especially worthwhile on vehicles that may sit for stretches between outings.
