The 2018 Mercedes-Benz S560 sits in the modern flagship luxury class, where long-wheelbase comfort, high-speed composure, and strong V8 performance all depend on the right tire setup. Whether the car is a sedan, coupe, or cabriolet, tire selection centers on a staggered radial fitment with different front and rear sizes and either 19-inch or 20-inch wheel diameters. That makes this page less about finding one universal tire and more about confirming the exact wheel package first. Available choices include Blackwall sport radials as well as select RWL and Redline options in the 20-inch sizes. The right pick should match the car's front-to-rear sizing, wheel diameter, appearance goals, and real road use.
Which Tire Size Is Right for The 2018 Mercedes-Benz S560
The 2018 Mercedes-Benz S560 uses four primary tire sizes across a staggered front-and-rear setup, and the first step is confirming whether the car has 19-inch or 20-inch wheels. Front tires are 245-section sizes and rear tires are 275-section sizes, so choosing the right tire means matching both wheel diameter and axle position before comparing brands, sidewall treatments, or tire series.
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 with a 245 millimeter section width, a 40-series aspect ratio, and a 20-inch rim diameter. On the 2018 Mercedes-Benz S560, this size serves the front position on 20-inch wheel setups, so it should be treated as part of a staggered fitment rather than a stand-alone all-around size. Available choices include BFGoodrich, Nitto, and Pro-Trac offerings, with Blackwall, RWL, and Redline sidewall treatments represented. This size makes sense when the car already runs 20-inch front wheels and the goal is to preserve the intended front axle sizing and overall stance.
Fit(s): 4Matic Coupe Front, 4Matic Sedan Front, Cabriolet Front, and Sedan Front
Construction: Radial|Rim: 19 in
245/45R19 is a metric radial size that combines a 245 millimeter section width with a 45-series profile on a 19-inch rim. For the 2018 Mercedes-Benz S560, it is the front tire size used with the 19-inch staggered package, pairing with a wider rear tire rather than matching front to rear. BFGoodrich and Nitto options are available here, all in Blackwall form across several sport-oriented radial series. This is the size to evaluate when the car retains 19-inch front wheels and the priority is staying with the proper front fitment for that wheel diameter.
Fit(s): 4Matic Coupe Rear, 4Matic Sedan Rear, Cabriolet Rear, and Sedan Rear
Construction: Radial|Rim: 20 in
275/35R20 is a metric radial size with a 275 millimeter section width, a 35-series profile, and a 20-inch rim diameter. On the 2018 Mercedes-Benz S560, this is the rear tire size for the 20-inch staggered arrangement, giving the car a wider rear footprint than the front axle uses. Product choices include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, RWL, and Redline styles available depending on the tire series. This size should be chosen only after confirming a 20-inch rear wheel, since rear axle sizing on the S560 is separate from the front fitment.
Fit(s): 4Matic Coupe Rear, 4Matic Sedan Rear, Cabriolet Rear, and Sedan Rear
Construction: Radial|Rim: 19 in
275/40R19 is a metric radial size that uses a 275 millimeter section width, a 40-series aspect ratio, and a 19-inch rim diameter. For the 2018 Mercedes-Benz S560, it fills the rear position on 19-inch wheel setups and works as the wider half of the factory-style staggered arrangement. BFGoodrich and Nitto offerings cover this size, with Blackwall sidewalls across several g-Force and NT555 G2 series choices. It is the correct rear size to review when the car has 19-inch rear wheels and the tire package needs to stay properly matched front to rear.
Sub-model fitment on the 2018 Mercedes-Benz S560 follows the same basic pattern across sedan, 4Matic sedan, 4Matic coupe, and cabriolet configurations: narrower front tires and wider rear tires, with either 19-inch or 20-inch wheels. Checking the exact front or rear position still matters, because the car does not use one square tire size at all four corners.

2018 Mercedes-Benz S560 4Matic Coupe Front
The 2018 Mercedes-Benz S560 4Matic Coupe Front uses a 245-section radial front tire and may be equipped with either a 19-inch or 20-inch front wheel. Tire selection starts with wheel diameter confirmation, then moves to comparing available sport-radial series and sidewall treatments within the matching front size.
The 2018 Mercedes-Benz S560 4Matic Coupe Rear uses a wider 275-section radial rear tire, again tied to either a 19-inch or 20-inch rear wheel package. That makes rear tire choice dependent on the installed wheel diameter and on keeping the staggered relationship with the corresponding front tire.
The 2018 Mercedes-Benz S560 4Matic Sedan Front follows the same staggered radial strategy, using a 245-section tire on the front axle in either 19-inch or 20-inch form. The practical step is confirming the wheel size on the car, then selecting among the available front-tire brands and series in that exact fitment.
The 2018 Mercedes-Benz S560 4Matic Sedan Rear uses the wider rear half of the staggered setup, with a 275-section radial tire on either a 19-inch or 20-inch wheel. Rear tire selection should stay matched to the correct axle position and wheel diameter rather than treating rear sizing as interchangeable with the front.
The 2018 Mercedes-Benz S560 Cabriolet Front uses a 245-section radial front size and can be equipped with either 19-inch or 20-inch front wheels. Choosing the right tire means matching the installed wheel package first, then deciding whether a Blackwall, RWL, or Redline presentation matters for the overall look.
The 2018 Mercedes-Benz S560 Cabriolet Rear uses a 275-section radial tire on the rear axle, with sizing tied to either 19-inch or 20-inch wheels. That wider rear fitment should be kept in step with the front axle setup so the car's staggered layout remains consistent.
The 2018 Mercedes-Benz S560 Sedan Front uses a 245-section radial tire and may carry either the 19-inch or 20-inch front size depending on wheel package. The main buying decision is confirming the actual front wheel diameter before comparing the available tire series and sidewall styles.
The 2018 Mercedes-Benz S560 Sedan Rear uses the wider 275-section radial rear fitment, available in 19-inch or 20-inch sizes to match the wheel package.

Best 2018 Mercedes-Benz S560 Tires for Sale
Available 2018 Mercedes-Benz S560 tires center on 19-inch and 20-inch sport-radial fitments from BFGoodrich, Nitto, and Pro-Trac. Buyers can compare tire series such as g-Force, NT555 G2, and Street Pro III, with Blackwall choices throughout and RWL or Redline treatments in select 20-inch sizes.
These FAQs focus on the staggered tire sizing used on the 2018 Mercedes-Benz S560, along with wheel-diameter confirmation, front-versus-rear fitment, construction, sidewall choices, and the basic checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2018 Mercedes-Benz S560?
The 2018 Mercedes-Benz S560 uses a staggered radial tire setup rather than one size at all four corners. Front fitment is either 245/45R19 or 245/40R20, while rear fitment is either 275/40R19 or 275/35R20, depending on the wheel package installed on the car.
That means the first step is identifying both axle position and wheel diameter before choosing a tire. A front 245-section tire is not the same fitment as the rear 275-section tire, and a 19-inch setup should not be mixed casually with a 20-inch setup without checking the full wheel-and-tire package.
What size rim does a 2018 Mercedes-Benz S560 use?
A 2018 Mercedes-Benz S560 uses either 19-inch or 20-inch rims, depending on the tire size installed. The 245/45R19 and 275/40R19 sizes mount on 19-inch wheels, while the 245/40R20 and 275/35R20 sizes mount on 20-inch wheels.
Rim diameter is the most important fitment check on this car because every tire size is tied directly to either a 19-inch or 20-inch wheel. Before comparing brands or sidewall styles, confirm the actual wheel diameter on the front and rear of the car, especially if the vehicle has changed hands or received aftermarket wheels.
Do all 2018 Mercedes-Benz S560 sub-models use the same tire size?
The covered 2018 Mercedes-Benz S560 sub-models share the same general staggered pattern, but they do not use one single tire size across every position. Front applications use either 245/45R19 or 245/40R20, while rear applications use either 275/40R19 or 275/35R20.
That makes sub-model identification helpful, but wheel package and axle position are the real deciding factors. A sedan, coupe, or cabriolet still needs the correct front size and the correct rear size for its installed 19-inch or 20-inch wheels, so checking the current setup on the car is essential before purchase.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Mercedes-Benz S560?
Start with the exact front or rear tire size and confirm whether the car has 19-inch or 20-inch wheels. The 2018 Mercedes-Benz S560 uses only radial tires in these fitments, so the main choices are matching the correct staggered size, selecting a tire series, and deciding whether appearance details such as Blackwall, RWL, or Redline matter.
After size confirmation, compare the tire's intended character and wheel compatibility. Rim-width recommendations, load figures where stated, and the visual style of the sidewall can all influence the final choice, especially on a premium car where stance, steering feel, and overall presentation matter as much as raw fitment.
What sidewall styles are available for 2018 Mercedes-Benz S560 tires?
Blackwall is the most common sidewall style available for the 2018 Mercedes-Benz S560 tire sizes. In the 20-inch front and rear sizes, select Pro-Trac Street Pro III options also appear with RWL and Redline sidewall treatments, giving the car a more customized look than a standard Blackwall presentation.
Sidewall style does not change the need to match the exact size and wheel diameter, but it can change the visual character of the car significantly. A Blackwall look keeps things understated, while RWL or Redline creates a more assertive appearance, particularly on a coupe or cabriolet with large-diameter wheels and a sportier stance.
What brands offer tires for the 2018 Mercedes-Benz S560?
Tires for the 2018 Mercedes-Benz S560 are available from BFGoodrich, Nitto, and Pro-Trac across the covered 19-inch and 20-inch sizes. Depending on the exact fitment, choices include g-Force series tires from BFGoodrich, NT555 G2 from Nitto, and Street Pro III from Pro-Trac.
Brand selection should come after the size, axle position, and wheel diameter are confirmed. Once those basics are settled, the comparison becomes more about the tire series available in that exact fitment, the sidewall treatment offered, and any published rim-width or load information that helps narrow the right match for the car.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Mercedes-Benz S560?
A period-style approach on a 2018 Mercedes-Benz S560 usually starts with preserving the proper staggered sizing and wheel diameter rather than changing the fitment theme. That means staying with the correct 19-inch or 20-inch front and rear radial sizes first, then selecting a tire series and sidewall style that suit the car's luxury-performance character.
Blackwall tires keep the presentation closer to the understated look many late-model luxury cars wear, while RWL or Redline choices create a more customized visual statement in the 20-inch sizes. When exact appearance authenticity matters, compare the car against original sales literature, period photos, or marque-specific guidance before making a visual change.
How does tire construction affect the appearance of a restored 2018 Mercedes-Benz S560?
Construction is straightforward on the 2018 Mercedes-Benz S560 because the primary fitments are all radial. The appearance differences come less from bias-ply versus radial decisions and more from sidewall treatment, tread presentation, and keeping the correct front-to-rear proportions that the staggered layout gives the car.
A mismatched wheel diameter or incorrect front and rear pairing can alter the car's visual balance more than many buyers expect. Keeping the proper 245-section front and 275-section rear sizing for the installed wheel package helps preserve the intended stance, while sidewall choices such as Blackwall, RWL, or Redline fine-tune the final look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Mercedes-Benz S560?
Yes. Any change to wheel diameter, wheel width, offset, ride height, or suspension settings can affect tire fitment on a 2018 Mercedes-Benz S560. Because the car uses a staggered setup with different front and rear sizes, even a small change can influence inner clearance, fender clearance, and the relationship between the front and rear tire package.
A modified S560 should be checked carefully before replacing tires by size alone. Confirm the actual wheels on the car, make sure the axle positions still match the intended tire sizes, and inspect clearance at full steering lock and through suspension travel so the new tires suit the current setup rather than the original wheel package.
What should I inspect before driving a 2018 Mercedes-Benz S560 on new tires?
Before road use, inspect inflation pressure, lug torque, tread and sidewall condition, and the tire's seating on the wheel. On a 2018 Mercedes-Benz S560, it is also important to confirm that the correct 19-inch or 20-inch front and rear sizes were installed in the proper positions, since the car uses a staggered arrangement.
A short initial check can prevent a larger fitment problem later. Look for rubbing near liners or suspension components, confirm that the steering turns freely, and watch for any unusual vibration after installation. Even with the correct size, wheel condition, alignment, and prior modifications can influence how the new tires behave on the road.
How often should tires on a 2018 Mercedes-Benz S560 be inspected?
Tires on a 2018 Mercedes-Benz S560 should be inspected regularly, not just when tread looks low. A quick visual check for air loss, uneven wear, cuts, bulges, or sidewall damage is worthwhile before routine driving, and a more careful inspection makes sense before longer highway trips or after the car has been parked for extended periods.
Low-use luxury cars can age tires quietly even when mileage stays modest. Keeping pressures consistent, watching for wear differences between front and rear, and inspecting for signs of aging helps protect ride quality and fitment integrity. The staggered layout also makes tire rotation patterns less straightforward, so condition checks become even more important.
