The 2021 Mercedes-Benz S560 sits at the luxury end of the grand touring spectrum, blending big-coupe and cabriolet style with the kind of speed, weight, and refinement that make tire choice especially important. On this model, fitment centers on staggered radial sizes, with 19-inch and 20-inch front and rear pairings depending on the wheel setup. That means the real decision is not just size, but matching the correct front and rear combination while choosing among blackwall, redline, or raised white letter styles in several performance-oriented tire series. Before selecting tires, confirm the wheel diameter on the car and keep the car's appearance goals and road-use expectations in mind.
Which Tire Size Is Right for The 2021 Mercedes-Benz S560
The 2021 Mercedes-Benz S560 uses four primary tire sizes because fitment is split between front and rear positions and also between 19-inch and 20-inch wheel packages. The first step is confirming the wheel diameter on the car, then matching the correct front and rear staggered sizes for that setup. Once that is settled, the choice shifts to tire series, sidewall style, and brand within the proper radial sizes.
245/40R20 is a metric radial size in which 245 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2021 Mercedes-Benz S560, this size serves the front position on 20-inch wheel applications. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter styling depending on the tire series. This size is the right place to start when the car has 20-inch front wheels and the goal is to preserve the proper staggered setup.
245/45R19 is a metric radial size with a 245-millimeter nominal section width, a 45-series profile, and a 19-inch rim diameter. On the 2021 Mercedes-Benz S560, it is the front tire size for 19-inch wheel configurations rather than a rear fitment. Product choices in this size include BFGoodrich and Nitto in blackwall designs across several g-Force and NT555 G2 series options. This size should be considered when the car is running 19-inch front wheels and you want to keep the intended front-to-rear sizing relationship intact.
275/35R20 is a wider metric radial size, with 275 indicating nominal section width in millimeters, 35 representing the aspect ratio, and 20 showing the required rim diameter. On the 2021 Mercedes-Benz S560, this size is used at the rear with 20-inch wheel packages, pairing with a narrower 20-inch front tire for a staggered arrangement. BFGoodrich, Nitto, and Pro-Trac offer choices here, with blackwall, redline, and raised white letter sidewall treatments available. This is the rear size to evaluate when the car wears 20-inch wheels and you want the proper staggered rear proportion.
275/40R19 is a metric radial tire size that combines a 275-millimeter nominal section width with a 40-series profile on a 19-inch rim. For the 2021 Mercedes-Benz S560, this is the rear size used with 19-inch wheel setups, so it belongs in a matched front-and-rear combination rather than as a stand-alone choice. Available options center on BFGoodrich and Nitto, mostly in blackwall form, with g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series coverage. It is the correct rear size to review when confirming a 19-inch staggered package.
Fitment on the 2021 Mercedes-Benz S560 is straightforward once the exact body style and axle position are identified. Both the 4Matic Coupe and Cabriolet use the same front and rear size pattern, but tire selection still depends on confirming whether the car has 19-inch or 20-inch wheels.

2021 Mercedes-Benz S560 4Matic Coupe Front
The 2021 Mercedes-Benz S560 4Matic Coupe Front uses a radial front tire in either a 19-inch or 20-inch fitment. That means the main selection step is confirming wheel diameter, then choosing among the available front-tire brands, series, and sidewall treatments that suit the car's overall look and use.
The 2021 Mercedes-Benz S560 4Matic Coupe Rear uses a wider radial rear tire matched to the front in a staggered setup, with 19-inch and 20-inch options. Rear tire choice should stay coordinated with the front wheel package so the car keeps the intended front-to-rear balance and visual proportion.
The 2021 Mercedes-Benz S560 Cabriolet Front follows the same radial front fitment pattern as the coupe, using either a 19-inch or 20-inch size depending on the wheel package. Once the wheel diameter is confirmed, the decision becomes a matter of selecting the right tire series and sidewall presentation for the car's appearance and driving use.
The 2021 Mercedes-Benz S560 Cabriolet Rear uses the same wider radial rear fitment pattern as the coupe, again split between 19-inch and 20-inch staggered combinations. Tire choice here should focus on keeping the rear size matched to the front setup while comparing the available blackwall or custom-style sidewall options where offered.
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:

Tire Size & Fitment
What tire size fits a 2021 Mercedes-Benz S560?
The 2021 Mercedes-Benz S560 uses a staggered radial setup rather than one universal size. Front fitment is 245/45R19 or 245/40R20, and rear fitment is 275/40R19 or 275/35R20, depending on whether the car has a 19-inch or 20-inch wheel package.
That means tire selection starts with confirming the wheel diameter on the car and then matching the proper front and rear pair. A front size should not be chosen as a rear tire, and a 19-inch setup should not be mixed casually with a 20-inch setup. If the car has aftermarket wheels, verify the actual wheel dimensions before choosing replacement tires.
What size rim does a 2021 Mercedes-Benz S560 use?
The 2021 Mercedes-Benz S560 uses either 19-inch or 20-inch rims, depending on the wheel package. The 19-inch setup pairs 245/45R19 fronts with 275/40R19 rears, while the 20-inch setup pairs 245/40R20 fronts with 275/35R20 rears.
Rim diameter is the first fitment detail to confirm because it determines which tire sizes belong on the car at all. After that, wheel width still matters when comparing specific tire options, especially on a staggered luxury coupe or cabriolet. A quick check of the wheel markings or the currently mounted tire size usually clarifies whether the car is on the 19-inch or 20-inch arrangement.
Do all 2021 Mercedes-Benz S560 sub-models use the same tire size?
The 2021 Mercedes-Benz S560 4Matic Coupe and Cabriolet follow the same basic fitment pattern, with narrower front tires and wider rear tires in a staggered radial setup. Both body styles use either the 19-inch combination or the 20-inch combination, rather than different size patterns for coupe versus cabriolet.
What changes the tire choice is not the body style so much as wheel diameter and axle position. Front and rear sizes are different, so the correct pair has to stay together. Checking the actual wheels on the car is still important, especially if the vehicle has been changed from its original wheel package or fitted with a different seasonal or aftermarket setup.
Choosing the Right Tire
What should I consider when choosing a 2021 Mercedes-Benz S560 tire?
Start with the correct size for the car's wheel package and axle position, since the 2021 Mercedes-Benz S560 uses staggered front and rear fitment in either 19-inch or 20-inch form. After size is settled, compare construction, brand, tire series, sidewall style, and any rim-width or load details that apply to the specific tire.
The best choice depends on how the car is used and how you want it to look. A blackwall performance-oriented radial keeps a modern presentation, while redline or raised white letter options can change the visual character on select 20-inch sizes. It also helps to confirm that the wheel width falls within the tire's usable range before making a final selection.
What sidewall styles are available for 2021 Mercedes-Benz S560 tires?
Sidewall style depends on the exact size. Blackwall options are available across all four primary sizes, while redline and raised white letter choices appear on select 20-inch sizes, including 245/40R20 and 275/35R20 through the Pro-Trac Street Pro III line.
That gives the S560 owner a real appearance choice beyond size alone. Blackwall keeps the most understated late-model luxury look, while redline or raised white letter styling creates a more customized presentation. Since those alternate sidewall treatments are tied to certain sizes, confirm the car's wheel diameter and front or rear position first before narrowing the style decision.
What brands offer tires for the 2021 Mercedes-Benz S560?
Available brands for the 2021 Mercedes-Benz S560 include BFGoodrich, Nitto, and Pro-Trac, depending on the tire size. BFGoodrich appears across all four sizes in several g-Force series, Nitto offers NT555 G2 choices, and Pro-Trac appears on select 20-inch fitments with Street Pro III options.
Brand matters mainly as part of the overall tire package rather than as a stand-alone decision. It is more useful to compare which brand offers the correct size, the sidewall style you want, and any rim-width or load details that suit the car's setup. On a staggered vehicle, it also helps to check whether the preferred series is available in both front and rear sizes.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2021 Mercedes-Benz S560?
On a 2021 Mercedes-Benz S560, tire construction is radial throughout, so the appearance question is less about bias-ply versus radial and more about the sidewall treatment and tire series. Blackwall tires keep a contemporary luxury-performance look, while redline or raised white letter options create a more customized visual statement on certain 20-inch sizes.
For an owner focused on preserving the car's original character, the safest starting point is the correct staggered size paired with a restrained sidewall presentation. A more personalized build may lean toward the available style accents instead. Since appearance can vary noticeably between front and rear tires, choose the full set with the car's overall visual balance in mind.
Does correct tire fitment matter for a 2021 Mercedes-Benz S560 restoration or preservation project?
Correct tire fitment matters on the 2021 Mercedes-Benz S560 because the car uses a staggered front-and-rear arrangement tied to either a 19-inch or 20-inch wheel package. Keeping the proper width and rim-diameter relationship preserves the intended stance and avoids the mismatched look that can come from mixing incorrect front and rear sizes.
Appearance is only part of the equation. The wrong size can also complicate wheel-to-tire proportion, clearance, and overall presentation on a modern grand touring Mercedes. A preservation-minded owner should verify the actual wheel package on the car first, then choose a tire style that supports the look being pursued without straying from the correct front and rear fitment pattern.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Mercedes-Benz S560?
Yes. Wheel changes, suspension alterations, lowering, spacers, or body modifications can all affect tire fitment on a 2021 Mercedes-Benz S560, especially because the car already uses staggered front and rear sizing. Even when the tire size matches one of the accepted 19-inch or 20-inch combinations, the surrounding setup can still change clearance.
A modified car should be checked for wheel diameter, wheel width, and enough room at the fenders and suspension before replacement tires are chosen. Steering clearance up front and inner clearance at the rear both matter. On a luxury coupe or cabriolet with large wheels, small setup changes can alter what works comfortably, so it pays to verify the actual configuration instead of assuming stock dimensions remain.
What should I inspect before driving a 2021 Mercedes-Benz S560 on new tires?
Before driving a 2021 Mercedes-Benz S560 on new tires, inspect the wheel diameter and tire size pairing to make sure the correct front and rear staggered combination has been installed. It is also worth checking inflation pressure, valve condition, visible tread and sidewall integrity, and whether the tires sit cleanly on the wheels without rubbing or uneven clearance.
A short road test should follow, paying attention to steering feel, vibration, and any contact sounds during turns or over suspension movement. Recheck pressures after the initial drive and look again for signs of interference. Since the S560 can wear either 19-inch or 20-inch combinations, a quick visual confirmation of front-versus-rear size is a smart final step before regular road use.
How often should tires on a 2021 Mercedes-Benz S560 be inspected?
Tires on a 2021 Mercedes-Benz S560 should be inspected regularly, especially on a vehicle that may see seasonal use, long storage periods, or intermittent driving. A routine check should include tread condition, cuts, cracking, bulges, uneven wear, air loss, and confirmation that the front and rear tires remain in the proper staggered positions.
Storage and low annual mileage do not eliminate tire aging, so visual condition matters just as much as tread depth on a collector-kept luxury car. It also helps to check pressures before longer drives and after the car has been sitting. Consistent inspection is particularly important on large-diameter 19-inch and 20-inch fitments, where underinflation or clearance issues can become noticeable quickly.
