The 2020 Mercedes-Benz S560 sits at the modern luxury end of the S-Class lineup, where quiet high-speed touring, substantial curb presence, and precise road manners all depend on getting tire fitment right. On this model, tire selection is tied closely to body style and wheel package, with sedan applications using 245/50R18 or staggered front and rear combinations in 19-inch or 20-inch sizes, and coupe and cabriolet configurations using staggered front and rear fitments as well. All primary fitments are radial, and available choices range from blackwall performance-oriented designs to RWL and redline options in certain sizes. The key is matching the exact sub-model and axle position before comparing style, series, and wheel compatibility.
Which Tire Size Is Right for The 2020 Mercedes-Benz S560
The 2020 Mercedes-Benz S560 uses five primary tire sizes, and the right one depends on the exact sub-model, axle position, and wheel diameter. Some sedan versions use a square 245/50R18 setup, while staggered applications pair narrower front tires with wider rear tires in 19-inch or 20-inch sizes. Before choosing a tire, confirm whether the car is a sedan, coupe, or cabriolet and whether it uses front, rear, 18-inch, 19-inch, or 20-inch fitment.
Fit(s): 4Matic Coupe Front, 4Matic Sedan Front, Cabriolet Front, and Sedan Front
Construction: Radial|Rim: 20 in
245/40R20 is a metric radial size in which 245 is the section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2020 Mercedes-Benz S560, this size serves as a front fitment on staggered 20-inch applications rather than a universal size across every configuration. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, RWL, and redline sidewall treatments represented. This size is the one to evaluate when keeping the correct front-to-rear stagger on a 20-inch setup.
Fit(s): 4Matic Coupe Front, 4Matic Sedan Front, Cabriolet Front, and Sedan Front
Construction: Radial|Rim: 19 in
245/45R19 follows the same metric radial format, with a 245-millimeter nominal section width, a 45-series profile, radial construction, and a 19-inch rim diameter. For the 2020 Mercedes-Benz S560, it functions as a front fitment on staggered 19-inch combinations used on certain configurations. BFGoodrich and Nitto choices appear in this size, largely in blackwall performance-oriented series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the front size to confirm when the car uses 19-inch wheels and a wider rear tire.
Fit(s): 4Matic Coupe Rear, 4Matic Sedan Rear, Cabriolet Rear, and Sedan Rear
Construction: Radial|Rim: 20 in
275/35R20 is a wider metric radial size, with 275 indicating the nominal section width in millimeters, 35 identifying the low-profile sidewall, and 20 matching a 20-inch wheel. On the 2020 Mercedes-Benz S560, this size is used as a rear fitment on staggered 20-inch applications, paired with a narrower front tire. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall options joined by RWL and redline versions in the Street Pro III series. This is the size to check when preserving the rear stance and wheel-width relationship of a 20-inch staggered setup.
Fit(s): 4Matic Coupe Rear, 4Matic Sedan Rear, Cabriolet Rear, and Sedan Rear
Construction: Radial|Rim: 19 in
275/40R19 uses a 275-millimeter nominal section width, a 40-series profile, radial construction, and a 19-inch wheel diameter. Within the 2020 Mercedes-Benz S560 range, it serves as the rear tire on staggered 19-inch applications, balancing with a narrower 19-inch front size. BFGoodrich and Nitto offer several choices here, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2, all in blackwall form. This rear size matters when the goal is to maintain the intended staggered arrangement on a 19-inch wheel package.
245/50R18 is a metric radial size with a 245-millimeter nominal section width, a 50-series aspect ratio, and an 18-inch rim diameter. On the 2020 Mercedes-Benz S560, this size appears on sedan applications that use a single tire size rather than a staggered front and rear layout. The available products in this size come from Pro-Trac in the Street Pro III series, with RWL and redline sidewall styles offering two distinct appearance directions. This is the size to focus on when the car uses 18-inch wheels and the same fitment at all four corners.
Tire fitment on the 2020 Mercedes-Benz S560 varies by both body style and axle position, so identifying the exact sub-model matters before comparing tires. Some sedan applications use one size all around, while coupe, cabriolet, and staggered sedan configurations split front and rear sizes across 19-inch or 20-inch wheels.

2020 Mercedes-Benz S560 4Matic Coupe Front
The 2020 Mercedes-Benz S560 4Matic Coupe Front uses a front-specific fitment within a staggered setup, with 19-inch and 20-inch front sizes available. Tire selection here starts with confirming which wheel package is on the car so the front tire matches the intended stagger and rim diameter.
The 2020 Mercedes-Benz S560 4Matic Coupe Rear uses the wider rear half of a staggered arrangement, again split between 19-inch and 20-inch applications. Rear tire choice should preserve the axle-specific size relationship rather than treating the coupe as a square four-corner fitment.
The 2020 Mercedes-Benz S560 4Matic Sedan uses a single-size radial fitment on 18-inch wheels rather than a staggered front and rear combination. That makes size selection more straightforward, shifting the decision toward sidewall style, series choice, and confirming the actual wheel setup on the car.
The 2020 Mercedes-Benz S560 4Matic Sedan Front uses a front-specific tire size when the sedan is equipped with a staggered 19-inch or 20-inch package. Choosing correctly means verifying both axle position and wheel diameter before comparing blackwall, RWL, or redline product options where available.
The 2020 Mercedes-Benz S560 4Matic Sedan Rear uses a wider rear radial tire on staggered wheel-package applications. Tire choice at the rear should be matched to the corresponding front fitment and the actual 19-inch or 20-inch wheel diameter on the vehicle.
The 2020 Mercedes-Benz S560 Cabriolet Front uses a staggered front fitment with either a 19-inch or 20-inch radial size. The practical step is confirming the wheel diameter first, then selecting the front tire that preserves the proper pairing with the wider rear size.
The 2020 Mercedes-Benz S560 Cabriolet Rear uses the wider rear size in a staggered setup, available in 19-inch and 20-inch forms. Rear tire selection should maintain the cabriolet's front-to-rear fitment balance and account for the exact wheel size already on the car.
The 2020 Mercedes-Benz S560 Sedan uses a single radial tire size on 18-inch wheels in this configuration. With no front-to-rear stagger to sort through, the main decision becomes choosing the sidewall presentation and tire series that best suits the car's use and appearance.
The 2020 Mercedes-Benz S560 Sedan Front uses a dedicated front size when equipped with a staggered 19-inch or 20-inch wheel package. The important step is to verify whether the sedan is actually on a staggered setup before selecting a front tire by size and rim diameter.
The 2020 Mercedes-Benz S560 Sedan Rear uses a wider rear tire when the car is equipped with a staggered wheel and tire arrangement. That makes axle position critical, since the rear fitment should be chosen to match the proper 19-inch or 20-inch front-and-rear combination.
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.

Owners of a 2020 Mercedes-Benz S560 usually need to sort out exact tire size by sub-model, axle position, and wheel diameter first. The questions below focus on fitment, staggered setups, product choice, appearance options, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2020 Mercedes-Benz S560?
The 2020 Mercedes-Benz S560 uses five primary tire sizes: 245/40R20, 245/45R19, 275/35R20, 275/40R19, and 245/50R18. The correct choice depends on whether the car is a sedan, coupe, or cabriolet, and whether it uses a square setup or a staggered front-and-rear arrangement.
The practical first step is identifying the exact sub-model and wheel package already on the vehicle. A sedan with 18-inch wheels may use 245/50R18 at all four corners, while staggered applications pair a narrower front tire with a wider rear tire in either 19-inch or 20-inch form.
What size rim does a 2020 Mercedes-Benz S560 use?
The 2020 Mercedes-Benz S560 uses 18-inch, 19-inch, and 20-inch rim diameters, depending on configuration. The 245/50R18 fitment corresponds to 18-inch wheels, the 245/45R19 and 275/40R19 sizes correspond to 19-inch wheels, and the 245/40R20 and 275/35R20 sizes correspond to 20-inch wheels.
Wheel diameter needs to be confirmed before any tire comparison because the S560 does not use one universal rim size across every sub-model. On staggered setups, front and rear wheel diameters match each other, but the tire widths differ by axle, so both rim size and axle position matter.
Why does the 2020 Mercedes-Benz S560 have more than one tire size?
The 2020 Mercedes-Benz S560 has more than one tire size because fitment changes with body style, wheel package, and whether the car uses a square or staggered arrangement. Some sedan applications use a single 245/50R18 size, while other sedan, coupe, and cabriolet versions use separate front and rear sizes in 19-inch or 20-inch form.
That means tire selection is not just a matter of matching the model name. Checking the exact configuration prevents mixing front and rear sizes incorrectly and helps confirm whether the car needs four matching tires or a staggered set with different widths from front to rear.
Choosing the Right Tire
What should I consider when choosing a 2020 Mercedes-Benz S560 tire?
Start with the correct size, axle position, and wheel diameter for the exact 2020 Mercedes-Benz S560 configuration. From there, compare whether the tire is intended for an 18-inch square setup or a 19-inch or 20-inch staggered setup, then look at construction details, series, sidewall style, and any stated rim-width or load specifications.
The right choice depends on how the car is used and how you want it to look. A blackwall performance-style tire may suit a more modern presentation, while RWL or redline options change the visual character noticeably in certain sizes without changing the need to match fitment correctly.
What sidewall styles are available for 2020 Mercedes-Benz S560 tires?
Sidewall style varies by size on the 2020 Mercedes-Benz S560. Blackwall options appear across several 19-inch and 20-inch sizes from BFGoodrich and Nitto, while Pro-Trac offers RWL and redline versions in 245/40R20, 275/35R20, and 245/50R18.
That gives the S560 owner a real appearance choice once the correct size has been confirmed. Blackwall keeps a more understated modern look, while raised white letter or redline sidewalls create a more distinct visual statement, especially on staggered cars where front and rear tires are already different widths.
What brands offer tires for the 2020 Mercedes-Benz S560?
Tires for the 2020 Mercedes-Benz S560 are available from BFGoodrich, Nitto, and Pro-Trac. Brand availability depends on the exact size, with BFGoodrich and Nitto appearing in several 19-inch and 20-inch fitments, and Pro-Trac covering certain 18-inch and 20-inch sizes with RWL and redline sidewall choices.
The useful comparison is less about brand ranking and more about which series, sidewall presentation, and wheel-fit specifications match the car. Once the right size is confirmed, compare the product details within that size so the tire suits both the vehicle setup and the appearance you want.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Mercedes-Benz S560?
A period-style approach on a 2020 Mercedes-Benz S560 starts with preserving the correct size, wheel diameter, and staggered or square layout used on the car. From there, the visual decision usually comes down to whether a blackwall presentation suits the car best or whether an RWL or redline sidewall creates the look you want in the sizes where those styles are offered.
Since this is a modern luxury Mercedes rather than an earlier collector-era fitment, appearance choices are more about taste than strict originality claims. Owners pursuing an exact delivery-style look should compare the car against original sales literature, window sticker details, or marque-specific references before settling on a sidewall treatment.
Does correct tire fitment matter for a 2020 Mercedes-Benz S560 restoration or preservation project?
Correct tire fitment matters because the 2020 Mercedes-Benz S560 uses multiple wheel diameters and, in many configurations, a staggered front-and-rear layout. Preserving the right size relationship helps keep the car visually balanced and avoids turning a carefully kept sedan, coupe, or cabriolet into something that looks obviously mismatched.
The most important details to preserve are the proper wheel diameter and the correct front or rear size for the exact configuration. Even on a newer preservation-minded vehicle, those basics influence both appearance and tire selection far more than brand name alone, especially when several sidewall styles are available.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Mercedes-Benz S560?
Yes, modifications can affect tire fitment on a 2020 Mercedes-Benz S560. Aftermarket wheels, suspension changes, ride-height changes, or body alterations can all change the clearances that matter on a car that may already use staggered front and rear tire sizes in 19-inch or 20-inch form.
That is why the tire size printed for the model should be treated as the starting point, not automatic proof of fit on every individual car. Wheel width, offset, steering clearance, and fender clearance are all worth checking before replacing tires on a modified S560.
What should I inspect before driving a 2020 Mercedes-Benz S560 on new tires?
Before driving a 2020 Mercedes-Benz S560 on new tires, inspect that the correct sizes were installed at the proper axle positions and that inflation is set appropriately for the tire and wheel setup. It also helps to confirm there is no visible rubbing at the fender, suspension, or steering components once the car is on the ground.
A short, careful road test is a sensible follow-up, especially on staggered applications where front and rear sizes differ. Pay attention to vibration, pull, unusual noise, or any sign of contact under steering lock, braking, or suspension movement so fitment issues can be addressed early.
What should I check before a longer drive in a 2020 Mercedes-Benz S560?
Before a longer drive, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or unusual wear. On a 2020 Mercedes-Benz S560, it is also worth confirming that the front and rear tires are the correct sizes for the car's specific configuration, since several versions use staggered fitment.
Cars that see limited use still deserve a close inspection because age, storage conditions, and slow air loss can affect road readiness. A quick look at wheel condition and a recheck for any clearance issue after recent tire installation can help prevent small fitment problems from becoming trip-ending ones.
