Mercedes-Benz S560 Tires

Mercedes-Benz S560 uses five tire sizes across the 2018 to 2021 production span: 245/40R20, 245/45R19, 275/35R20, 275/40R19, and 245/50R18. The 245/40R20 and 275/35R20 sizes use 20-inch rims, the 245/45R19 and 275/40R19 sizes use 19-inch rims, and the 245/50R18 size uses an 18-inch rim. The 18-inch size appears in 2019 and 2020, while the 19-inch and 20-inch combinations run through all four model years.

That size spread means a Mercedes-Benz S560 owner should not rely on model year alone. Start by reading the tire size placard or the tires currently on the car, then confirm the wheel diameter and whether the car uses a staggered setup with narrower front tires and wider rear tires. That step matters because the 19-inch and 20-inch combinations each use matched front and rear sizes, while the 18-inch option is limited to selected 2019 and 2020 cars.

A 2019 Mercedes-Benz S560 has 5 tire sizes listed because the model year includes more than one wheel package and more than one rim diameter. That year can fall into 18-inch, 19-inch, or 20-inch fitments, and the 19-inch and 20-inch arrangements also use staggered front-and-rear sizing with a narrower 245-section tire up front and a wider 275-section tire at the rear.

The practical takeaway is that a 2019 Mercedes-Benz S560 owner needs to identify the exact wheel package on the car rather than choosing by year alone. Check all four tires, because front and rear sizes may differ, and verify the wheel diameter directly from the wheel or the existing size code. Once the wheel diameter is confirmed, the correct front and rear pairing becomes much easier to sort out.

Mercedes-Benz S560 uses three rim diameters across the years covered here: 18-inch, 19-inch, and 20-inch. The 19-inch and 20-inch sizes appear from 2018 through 2021, while the 18-inch size appears in 2019 and 2020. Each tire size is tied directly to one rim diameter, so 245/50R18 is only for an 18-inch wheel, 245/45R19 and 275/40R19 are for 19-inch wheels, and 245/40R20 and 275/35R20 are for 20-inch wheels.

Wheel diameter is the first fitment checkpoint on a Mercedes-Benz S560 because no tire can compensate for the wrong rim size. Confirm the wheel diameter on the actual car before comparing widths and aspect ratios, especially if the car has had wheels changed during its life. After that, verify whether the car uses the same size all around or a staggered arrangement with different front and rear tires.

On a Mercedes-Benz S560, 245/40R20 means the tire has a nominal section width of 245 millimeters, a sidewall height equal to 40 percent of that width, radial construction, and a 20-inch rim diameter. The same logic applies to the other metric sizes in the range, so 245/45R19 and 245/50R18 remain 245 mm wide but use taller sidewalls and different wheel diameters, while 275/35R20 and 275/40R19 are wider rear-fitment sizes.

Reading the code correctly helps a Mercedes-Benz S560 owner understand why two tires can share the same width but still fit very different wheel packages. Width, aspect ratio, and rim diameter all work together, and changing one number changes the tire’s overall dimensions and intended application. That is why the full size code should always match the car’s required fitment rather than only matching one part of the number.

A 2020 Mercedes-Benz S560 can use 245/40R20, 275/35R20, 245/45R19, 275/40R19, or 245/50R18 depending on wheel package and axle position. The 20-inch setup uses a 245-section front tire and a 275-section rear tire, the 19-inch setup does the same with different aspect ratios, and the 18-inch size is a separate 245/50R18 fitment for selected cars in that year.

The cleanest way to confirm a 2020 Mercedes-Benz S560 fitment is to compare the existing tire codes on the car and note whether the front and rear match or differ. Then verify the wheel diameter directly. That process prevents the most common mistake on modern luxury sedans, which is ordering a front size for the rear axle or choosing the correct width with the wrong aspect ratio and rim diameter.

Mercedes-Benz S560 tire options include Blackwall, RWL, and Redline sidewall styles. Blackwall appears across the BFGoodrich and Nitto offerings in the 19-inch and 20-inch sizes, while RWL and Redline are available in Pro-Trac Street Pro III sizes including 245/40R20, 275/35R20, and 245/50R18. That gives the S560 a broader visual range than many late-model luxury fitments.

A Mercedes-Benz S560 owner choosing by appearance should still treat fitment as the priority and sidewall style as the finishing detail. Blackwall is the most understated and closest to the original luxury-sedan presentation, while RWL and Redline create a more custom or performance-oriented look. Once the correct size and wheel diameter are confirmed, sidewall style becomes the main aesthetic decision within the available options.

Mercedes-Benz S560 tires in these sizes are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in several g-Force series offerings, Nitto is represented by the NT555 G2, and Pro-Trac offers Street Pro III fitments in selected sizes. Together they cover the full spread of 18-inch, 19-inch, and 20-inch applications listed for the S560.

Brand choice on a Mercedes-Benz S560 usually comes after the fitment is settled, because not every brand appears in every size. Owners who want a uniform brand on all four corners should first confirm the exact front and rear sizes required, then compare which makers offer both positions. Buyers who are more focused on visual style may also find that sidewall treatment varies by brand and series.

Mercedes-Benz S560 tire series here include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, BFGoodrich g-Force Sport Comp 2, Nitto NT555 G2, and Pro-Trac Street Pro III. All are radial tires, but they differ in brand family, tread design line, and available sidewall presentation. Street Pro III also appears in RWL and Redline versions, while the BFGoodrich and Nitto options shown here are Blackwall.

For a Mercedes-Benz S560 owner, the practical difference between series is less about basic fitment and more about visual preference and the brand line available in the needed size. Start with the correct wheel diameter and axle-specific size, then compare which series are offered in that position. If the goal is a matched look front to rear, make sure the same series is available in both required sizes before finalizing the choice.

A Mercedes-Benz S560 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and large temperature swings when the tires are fitted. Because the car is heavy and often sits for long periods in collector or low-use ownership, maintaining proper inflation is especially important to reduce flat spotting and sidewall stress. Clean tires and wheels before storage so brake dust and road residue do not remain on the rubber.

If a Mercedes-Benz S560 will sit for extended stretches, moving the car periodically can help prevent one section of the tread from carrying the load continuously. Owners who keep the car on its tires rather than on stands should inspect pressures regularly during storage, not just before the next drive. That small routine goes a long way toward preserving ride quality and keeping an expensive wheel-and-tire package in better condition.

Tires on a Mercedes-Benz S560 should be inspected at regular intervals even if the car covers very few miles. Look for irregular wear, damage to the sidewall, punctures, cracking, and signs that the front and rear tires may have been rotated improperly on a staggered setup. Pressure should also be checked routinely, because a luxury sedan with low-profile tires can feel the effects of inflation changes quickly.

A useful habit is to inspect a Mercedes-Benz S560 before each extended drive and again after periods of storage. Since this model can use different sizes front and rear, confirm that the correct tire remains on each axle whenever the car has had service or wheel work. Frequent visual checks often catch small issues early, before they become ride, handling, or wheel-protection problems.

Tires on a Mercedes-Benz S560 should be replaced when age, cracking, impact damage, or structural changes appear, even if the tread still looks deep. Low-mileage collector use can disguise age-related deterioration because the tire may look presentable while the rubber has hardened or weakened over time. Uneven wear, persistent vibration, or visible sidewall distress are also strong reasons to move past tread depth as the deciding factor.

A Mercedes-Benz S560 owner should think of replacement in terms of condition and age as much as mileage, especially on cars that spend long periods parked. The car’s weight and speed capability put meaningful demands on the tires, so old rubber should not be kept in service simply because it has seen limited use. Periodic evaluation by a knowledgeable tire professional is a sensible part of long-term ownership.

These Mercedes-Benz S560 tire options are modern radial tires sized for public-road use when they are fitted in the correct size, mounted on the correct rim diameter, and kept in sound condition. The available sizes cover 18-inch, 19-inch, and 20-inch applications, and several options include high-speed style sizing with ZR markings in the product descriptions. Safety begins with matching the exact front and rear fitment required by the car.

A Mercedes-Benz S560 owner should treat correct sizing and condition as inseparable parts of road safety. The wrong axle placement, wrong rim diameter, or an aged tire can compromise how the car rides and responds even if the tire physically mounts. Before regular road use, confirm that all four tires are appropriate for the wheel package and that none show age-related or impact-related issues.

Before driving a Mercedes-Benz S560, check tire pressure, visible tread and sidewall condition, and confirm that the front and rear tires are the correct sizes for their positions. On this model, that matters because 245-section and 275-section sizes are paired on staggered 19-inch and 20-inch setups, while some 2019 and 2020 cars use an 18-inch fitment. Also look for cuts, bulges, and any sign of uneven wear.

That quick walk-around is especially valuable after the car has been parked for a while or after any service involving wheels and brakes. A Mercedes-Benz S560 can mask early tire issues with its refinement, so visual and pressure checks should come before relying on how the car feels on the road. Catching a mismatch or pressure problem before moving the car is far better than discovering it at speed.

A Mercedes-Benz S560 should only be driven at speeds appropriate to the exact tire fitted, its current condition, and the overall condition of the car. The sizes offered here are modern radial fitments rather than period-style antique tires, but speed capability still depends on using the correct specification in good condition and maintaining proper inflation. A luxury performance sedan places more sustained load on its tires than a casual cruiser does.

For practical ownership, a Mercedes-Benz S560 driver should avoid treating age, appearance, or brand name as a substitute for condition and proper fitment. If the tires are older, have been stored for long periods, or show any irregularities, moderate use and inspection come first. Matching the car’s capabilities starts with respecting the limits of the tire package that is actually on the car at that moment.
