The 2023 Mercedes-Benz EQS 580 sits at the sharp end of the modern luxury EV market, combining full-size comfort with the smooth, heavy, high-tech character expected from an electric flagship sedan. Tire choice on this car matters because wheel size is part of the setup, with 255/45R20 and 265/40R21 radial fitments used on the EQS 580 4Matic. That means the first decision is confirming which wheel diameter is on the car before comparing actual tire options. Within the available choices, sidewall treatment and tire series can change the look from understated blackwall to raised white letter or redline. Owners should match the tire to the wheel, the car's current setup, and the intended balance of appearance and road use.
Which Tire Size Is Right for The 2023 Mercedes-Benz EQS 580
The 2023 Mercedes-Benz EQS 580 uses two primary tire sizes, and the correct choice depends on wheel diameter first. The EQS 580 4Matic is found with either a 255/45R20 radial on a 20-inch rim or a 265/40R21 radial on a 21-inch rim, so identifying the exact wheel on the car is the key first step before comparing brands, sidewall styles, or tire series.
255/45R20 is a metric radial size in which 255 identifies the nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2023 Mercedes-Benz EQS 580, this size suits the 20-inch wheel setup and keeps the selection within modern radial construction. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments appearing in this size. It is the size to evaluate when the car is equipped with 20-inch wheels and the goal is to compare appearance and product character within that setup.
265/40R21 is a metric radial size where 265 identifies nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 21 is the wheel diameter in inches. For the 2023 Mercedes-Benz EQS 580, this size belongs to the 21-inch wheel configuration, so it is tied directly to the wheel package on the car. The practical takeaway is that this is not a substitute for the 20-inch fitment just because both sizes are used on the same model. Owners with 21-inch wheels should stay focused on 21-inch tire selection and verify clearance and wheel compatibility before considering any change.
Fitment is straightforward here because the covered sub-model uses the same two wheel-based tire options found on the model core. Checking the exact wheel diameter on the car still matters, since tire choice follows the 20-inch or 21-inch setup rather than a different trim-specific tire construction.

Tire Size & Fitment
What tire size fits a 2023 Mercedes-Benz EQS 580?
The 2023 Mercedes-Benz EQS 580 uses two primary tire sizes: 255/45R20 and 265/40R21. Both are radial tire fitments, and the correct one depends on which wheel diameter is installed on the car.
That makes wheel confirmation the first step, not just model identification. A 20-inch wheel calls for the 255/45R20 fitment, while a 21-inch wheel uses 265/40R21. If the car has been changed from its original wheel setup, check the actual wheel diameter and the complete tire size already mounted before choosing a replacement.
What size rim does a 2023 Mercedes-Benz EQS 580 use?
The 2023 Mercedes-Benz EQS 580 is found with either a 20-inch or 21-inch rim, depending on which tire size is on the car. The 255/45R20 fitment uses a 20-inch rim, and the 265/40R21 fitment uses a 21-inch rim.
Rim diameter is the non-negotiable part of the fitment because a 20-inch tire cannot be mounted on a 21-inch wheel, and the reverse is also true. Before replacing tires, read the size on the current sidewall and confirm the wheel itself, especially if the EQS has aftermarket wheels or a different wheel package than expected.
Why does the 2023 Mercedes-Benz EQS 580 have more than one tire size?
The 2023 Mercedes-Benz EQS 580 has more than one tire size because it is used with more than one wheel diameter. In this case, the EQS 580 4Matic can use either 255/45R20 or 265/40R21, both in radial construction.
This does not mean both sizes are interchangeable on the same wheel. It means the vehicle can appear with different wheel-and-tire packages, so the owner needs to match the replacement tire to the actual wheel diameter on the car. Once that is confirmed, the next decision becomes comparing available tire series, brands, and sidewall styles within that specific size.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2023 Mercedes-Benz EQS 580?
Start with the basics: the car must be on a 20-inch wheel, and the tire should match the 255/45R20 size. From there, compare radial tire options by brand, tire series, sidewall style, and any available load or rim-width specifications that affect how the tire suits the wheel and the intended use.
Available 255/45R20 choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline appearances in the mix. That gives the buyer room to choose a cleaner modern look or a more custom visual statement. It also helps to confirm the wheel width before narrowing the field, since some products include stated rim-width ranges.
What sidewall styles are available for 2023 Mercedes-Benz EQS 580 tires?
For the 255/45R20 fitment, available sidewall styles include Blackwall, RWL, and Redline. That creates a meaningful appearance choice within the same basic tire size, especially for an owner deciding whether to keep the presentation understated or give the car a more custom look.
Blackwall is the most subdued option, while RWL adds raised white lettering and Redline introduces a more pronounced period-inspired accent. Those style choices do not change the need to stay within the correct tire size and wheel diameter. The practical approach is to confirm fitment first, then choose the sidewall treatment that best matches the car's visual direction.
What brands offer tires for the 2023 Mercedes-Benz EQS 580?
The available 255/45R20 tire options for the 2023 Mercedes-Benz EQS 580 include BFGoodrich, Nitto, and Pro-Trac. Each brand appears in radial construction, but the product range differs by tire series and sidewall presentation rather than by a completely different fitment approach.
That means brand selection should come after confirming the wheel diameter and the exact tire size needed for the car. Once the fitment is settled, compare the available series and visual treatments within that size. The most useful side-by-side checks are rim-width compatibility, sidewall style, and the overall look the tire gives the EQS.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Mercedes-Benz EQS 580?
A period-style approach is less about historical restoration on a 2023 Mercedes-Benz EQS 580 and more about choosing a tire that gives the car the visual character you want while staying in the correct size. For the 255/45R20 fitment, that can mean comparing blackwall, RWL, and redline radial options.
The safest starting point is the exact wheel diameter and tire size already on the car, then narrowing the choice by appearance. Blackwall keeps the look cleaner and more contemporary, while RWL or redline adds a stronger custom statement. Any appearance-led choice still needs to be checked against the wheel setup and the way the car will actually be driven.
How does tire construction affect the appearance of a restored or customized 2023 Mercedes-Benz EQS 580?
On the 2023 Mercedes-Benz EQS 580, the primary fitments are radial tires, so the visual effect comes more from sidewall treatment and series selection than from choosing between bias-ply and radial construction. In the available 255/45R20 range, blackwall, raised white letter, and redline options each give the car a different personality.
That matters because the tire can either blend into the modern shape of the EQS or become a deliberate styling feature. A blackwall usually keeps the presentation restrained, while RWL and redline stand out more clearly. Owners building a custom look should keep the aesthetic choice secondary to proper wheel diameter, tire size, and overall fitment checks.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Mercedes-Benz EQS 580?
Yes. Wheel changes, altered offsets, suspension modifications, or body changes can all affect tire fitment on a 2023 Mercedes-Benz EQS 580 even when the tire size sounds close to stock. That matters on a car with both 20-inch and 21-inch wheel-based fitments, because the tire must match the actual wheel diameter and available space.
An EQS with aftermarket wheels should be checked for wheel width, inner and outer clearance, and steering or suspension interference before replacement tires are chosen. Even within the correct nominal size, a different wheel or modified ride height can change how the tire sits in the car. Verifying the current setup avoids costly mistakes.
What should I inspect before driving a 2023 Mercedes-Benz EQS 580 on new tires?
Before driving, inspect the installed tire size, confirm the wheel diameter, and make sure the tires are seated properly and inflated to the vehicle's required pressure. It also helps to check for any immediate signs of rubbing, uneven spacing to suspension components, or interference during full steering movement.
A short, careful road test is a smart follow-up after installation. Listen for contact noises, watch for vibration, and recheck pressure after the tires have settled. On a heavier luxury EV such as the EQS 580, keeping an eye on tire condition early can prevent premature wear and can quickly reveal a mismatch between the tire, wheel, and vehicle setup.
How often should tires on a 2023 Mercedes-Benz EQS 580 be inspected?
Tires on a 2023 Mercedes-Benz EQS 580 should be inspected regularly, not just when tread looks low. A routine visual check for uneven wear, cuts, bulges, cracking, and pressure loss is worthwhile throughout the year, and it becomes even more important if the car sees long highway trips or sits for stretches between drives.
Consistent inspections help catch alignment issues, wheel damage, or slow air loss before they become bigger problems. It is also wise to check the tires before a longer drive and after any impact with potholes or road debris. Staying ahead of condition changes matters on a luxury EV where tire load and road behavior are closely tied to everyday drivability.
