The 2023 Mercedes-Benz S580 sits at the top of the modern full-size luxury sedan market, blending long-wheelbase comfort, advanced technology, and the kind of quiet high-speed composure buyers expect from an S-Class. Tire selection matters here because the S580 uses multiple modern metric radial sizes depending on wheel package and front or rear position. That means the decision is less about vintage-style construction and more about matching the exact rim diameter and, on staggered setups, the correct axle-specific size. Available choices also introduce sidewall and series differences in certain sizes, especially 285/35R20. Before choosing, confirm whether the car has 19-, 20-, or 21-inch wheels and whether it uses a square or staggered setup.
Which Tire Size Is Right for The 2023 Mercedes-Benz S580
The 2023 Mercedes-Benz S580 uses five primary tire sizes, and the right one depends on wheel diameter, sub-model position, and whether the car has a square or staggered setup. Some S580 configurations use the same size at all four corners, while others split front and rear sizing. Confirming the exact wheel package and whether you are selecting a front or rear tire is the first step before comparing brands, series, or sidewall treatments.
255/40R20 is a metric radial size with a 255-millimeter section width, a 40-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2023 Mercedes-Benz S580, this size is part of the primary fitment range and is especially important to confirm against the vehicle's exact wheel package. Available product choice in this size centers on a Blackwall BFGoodrich g-Force Phenom T/A. This size makes sense when the car is equipped with 20-inch wheels and the goal is to match the correct front or all-around fitment rather than substitute across different rim diameters.
255/45R19 is a metric radial size that combines a 255-millimeter section width with a 45-series profile on a 19-inch wheel. Its radial construction suits the S580's modern luxury-sedan role, but the key point is that it belongs only with the correct 19-inch wheel setup. This size appears in the S580 fitment range as part of a square arrangement rather than a staggered front-and-rear pairing. It is the size to evaluate when the car retains its 19-inch wheels and you want to preserve the original wheel-diameter relationship without moving into 20- or 21-inch fitments.
255/35R21 is a metric radial size with a 255-millimeter section width, a lower 35-series profile, and a 21-inch rim diameter. On the 2023 Mercedes-Benz S580, it serves as a front-position size in a staggered setup, so it should not be treated as a universal fitment for every corner of the car. Its lower-profile construction aligns with a larger-wheel presentation and requires careful attention to axle position. This is the size to confirm when the S580 has 21-inch front wheels and needs the proper front tire rather than a square 19-inch or 20-inch arrangement.
285/30R21 is a metric radial size that uses a wider 285-millimeter section width, a 30-series profile, and a 21-inch rim diameter. Within the 2023 Mercedes-Benz S580 fitment range, this is a rear-position size for a staggered setup, making axle location just as important as wheel diameter. The wider section and lower-profile format distinguish it from the matching 255/35R21 front size, even though both use 21-inch rims. Choose this size only after confirming the car uses the 21-inch staggered arrangement and that the tire being replaced is on the rear axle.
285/35R20 is a metric radial size with a 285-millimeter section width, a 35-series profile, and a 20-inch rim diameter. On the 2023 Mercedes-Benz S580, it functions as a rear-position size in a staggered 20-inch setup, so it should be matched to the proper axle and wheel package. This size has the broadest visible product variety, including BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, RWL, and Redline sidewall treatments across g-Force Comp 2 AS, NT555 G2, and Street Pro III series. It is the size to study most closely when appearance and product character matter as much as basic rear fitment.
Sub-model fitment on the 2023 Mercedes-Benz S580 is not one-size-fits-all, because wheel diameter and front-to-rear sizing can change across the covered configurations. Checking the exact sub-model matters here so the tire matches the car's wheel package and, where applicable, the correct axle position.

2023 Mercedes-Benz S580 4Matic
The 2023 Mercedes-Benz S580 4Matic uses a square fitment with either 255/45R19 or 255/40R20 radial tires, depending on the wheel package installed. Tire selection starts with confirming whether the car has 19-inch or 20-inch wheels, then choosing within the available product options for that exact size.
The 2023 Mercedes-Benz S580 4Matic Front uses either 255/35R21 or 255/40R20 radial tires as the front axle size in a larger-wheel setup. That means the front tire should be matched to the actual wheel diameter on the car rather than assumed from the rear size or from another S580 configuration.
The 2023 Mercedes-Benz S580 4Matic Rear uses either 285/30R21 or 285/35R20 radial tires on the rear axle of a staggered setup. Rear-tire selection should focus on the correct wheel diameter first, then on the available brand and sidewall choices within that specific rear size.
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:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2023 Mercedes-Benz S580?
The 2023 Mercedes-Benz S580 uses five primary tire sizes: 255/45R19, 255/40R20, 255/35R21, 285/35R20, and 285/30R21. The exact fitment depends on wheel diameter and whether the car is using a square setup or a staggered front-and-rear arrangement.
The practical step is to confirm the wheel package already on the car before choosing a tire. A 19-inch size should not be treated as interchangeable with a 20- or 21-inch size, and a front staggered size should not be assumed to belong on the rear. Matching the existing wheel diameter and axle position is the safest starting point.
What size rim does a 2023 Mercedes-Benz S580 use?
A 2023 Mercedes-Benz S580 can use 19-inch, 20-inch, or 21-inch rims, depending on its configuration. The tire sizes tied to those diameters are 255/45R19 for 19-inch wheels, 255/40R20 and 285/35R20 for 20-inch wheels, and 255/35R21 with 285/30R21 for 21-inch wheels.
Wheel diameter is the first fitment detail to verify because it immediately narrows the tire choices. On staggered setups, the front and rear still share the same wheel diameter within that package, but they use different tire widths and aspect ratios. Checking the wheel itself avoids ordering a correct-looking tire in the wrong diameter.
Why does the 2023 Mercedes-Benz S580 have more than one tire size?
The 2023 Mercedes-Benz S580 has more than one tire size because it appears with different wheel packages and with both square and staggered arrangements. Some versions use the same width tire at all four corners, while others use a narrower front tire and a wider rear tire.
That means tire selection starts with identifying the exact setup on the car rather than relying only on the model name. Looking at the current tire sidewall, wheel diameter, and whether the front and rear sizes match will usually answer the question quickly. This matters especially on 20-inch and 21-inch staggered combinations.
Choosing the Right Tire
What should I consider when choosing a 285/35R20 tire for a 2023 Mercedes-Benz S580?
Start with the basics: 285/35R20 must match a rear-position 20-inch fitment on the 2023 Mercedes-Benz S580. Within that size, available choices differ by brand and series, including BFGoodrich g-Force Comp 2 AS, Nitto NT555 G2, and Pro-Trac Street Pro III, with Blackwall, RWL, and Redline sidewall treatments.
The best comparison points are appearance, intended use, and wheel compatibility. One 285/35R20 product also states a 9.5- to 11.0-inch rim-width range, which is useful when confirming wheel match. Buyers who want a discreet modern look may prefer Blackwall, while RWL or Redline can shift the car's visual character without changing the size itself.
What sidewall styles are available for 2023 Mercedes-Benz S580 tires?
Sidewall style depends on the exact tire size, but the available S580 product range includes Blackwall, RWL, and Redline treatments. Blackwall appears in both 255/40R20 and 285/35R20, while RWL and Redline are present within the 285/35R20 rear-size options.
That makes sidewall appearance more of a product-level decision than a vehicle-wide one. A buyer replacing only rear tires in 285/35R20 has more visual choice than someone shopping 255/40R20. The simplest way to avoid mismatched appearance is to compare the sidewall treatment already on the car with the exact axle and size being replaced.
What brands offer tires for the 2023 Mercedes-Benz S580?
The current product selection for the 2023 Mercedes-Benz S580 includes BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both 255/40R20 and 285/35R20, while Nitto and Pro-Trac appear in 285/35R20 rear-size options.
Brand should be compared alongside the exact size, tire series, and sidewall style rather than treated as the only decision point. A square 19-inch or 20-inch setup may have a different choice range than a staggered rear fitment. Matching the correct size first keeps the comparison grounded in what actually belongs on the car's wheel package.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Mercedes-Benz S580?
A period-style approach on a 2023 Mercedes-Benz S580 usually means preserving the exact wheel diameter and original overall visual theme of the car rather than chasing a vintage look. Since the S580 is a modern luxury sedan with radial metric fitments, staying with the correct 19-, 20-, or 21-inch size is the foundation.
Appearance choice comes next. Blackwall keeps the presentation restrained and contemporary, while certain 285/35R20 options introduce RWL or Redline styling that changes the car's personality. Buyers focused on preserving the car's intended design language should compare sidewall treatment carefully and avoid mixing visual styles front to rear unless the full set is being changed.
How does tire construction affect the appearance of a restored 2023 Mercedes-Benz S580?
Construction is straightforward on the 2023 Mercedes-Benz S580 because its primary fitments are radial tires throughout. That means the visual difference is less about choosing between bias-ply and radial and more about selecting the correct metric size, profile, and sidewall presentation for the wheel package already on the car.
On a modern S-Class, an incorrect profile or mismatched front and rear size usually affects appearance faster than the brand name does. A taller or lower-profile look than intended can change the wheel-to-tire balance noticeably. Keeping the correct front and rear sizing relationship is the cleanest way to preserve the sedan's designed stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Mercedes-Benz S580?
Yes. Aftermarket wheels, suspension changes, spacers, or body modifications can affect tire fitment on a 2023 Mercedes-Benz S580 even when the tire size appears close to a stock option. That matters most on staggered 20-inch and 21-inch setups, where front and rear sizes already differ by width and profile.
Any modified S580 should be checked for wheel diameter, wheel width, offset, and clearance at full steering lock and suspension movement before a new tire is chosen. A size that belongs on one factory wheel package should not be assumed to suit a modified setup automatically. The more the car has changed, the more important those checks become.
What should I inspect before driving a 2023 Mercedes-Benz S580 on new tires?
Before road use, inspect the new tires for the correct size on the correct axle, proper air pressure, and secure mounting on the intended wheel diameter. It also helps to look for any visible issues such as sidewall damage, bead-seating problems, or interference around suspension and fender areas.
A quick check after the first short drive is worthwhile as well. Reconfirm pressure, make sure there is no rubbing during turns or over bumps, and verify that staggered front and rear sizes were not accidentally crossed. On a vehicle as sensitive to ride quality as the S580, small fitment mistakes tend to show up early.
How often should tires on a 2023 Mercedes-Benz S580 be inspected?
Tires on a 2023 Mercedes-Benz S580 should be inspected regularly, not just when tread looks low. Pressure, tread wear, sidewall condition, and any signs of impact damage deserve routine attention, especially on lower-profile 20-inch and 21-inch fitments that can be more vulnerable to pothole or curb contact.
A practical habit is to check them monthly and again before a longer drive. Uneven wear can also reveal alignment or suspension issues that affect tire life and road manners. On staggered setups, inspect front and rear sizes as separate fitments so wear patterns are judged against the correct axle rather than compared as if all four are identical.
