The 2011 Mercedes-Benz S600 sits at the top of the W221 S-Class range, combining long-wheelbase luxury with the kind of power and weight that make tire selection more than a cosmetic decision. On this car, fitment centers on staggered radial sizes, with front and rear tires differing in width and with separate wheel packages depending on whether the car is in Base or Sport Package form. That makes the real choice less about whether the S600 uses radial tires and more about matching the exact front and rear sizes, wheel diameter, and preferred sidewall presentation. For a well-kept road car, appearance, load capability, and wheel compatibility all deserve close attention.
Which Tire Size Is Right for The 2011 Mercedes-Benz S600
The 2011 Mercedes-Benz S600 uses six primary tire sizes, and the correct fitment depends first on whether the car is Base or w/Sport Pkg., then on whether you are selecting a front or rear tire. This is also a multi-diameter fitment, covering 18-inch, 19-inch, and 20-inch wheels, so confirming the actual wheel diameter on the car is essential before choosing a tire. Every primary fitment here is radial, and the main decision is matching the correct staggered size pair while comparing brands, series, and sidewall style options where available.
255/45R18 is a metric radial size that uses a 255-millimeter nominal section width, a 45-series profile, and an 18-inch rim diameter. On the 2011 Mercedes-Benz S600, this size serves as a front fitment in Base form and keeps the car in a modern radial construction. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with Blackwall, RWL, and Redline sidewall treatments appearing in this size. It is the size to evaluate when the car retains the standard 18-inch front wheel setup and the goal is to match that configuration rather than move to a sport wheel package.
275/45R18 is a metric radial size with a 275-millimeter nominal section width, a 45-series profile, and an 18-inch rim diameter. On the 2011 Mercedes-Benz S600, it functions as the rear companion to the Base front fitment, creating the correct staggered width relationship for that wheel package. Product choice in this size is much narrower than in several of the front and sport-package sizes, so the decision is more about confirming the correct rear wheel and intended use than comparing several sidewall styles. This size matters when the car still uses the standard 18-inch rear setup and needs the matching rear tire width.
255/35R20 is a metric radial size with a 255-millimeter nominal section width, a 35-series profile, and a 20-inch rim diameter. On the 2011 Mercedes-Benz S600, it is one of the front tire sizes used on the w/Sport Pkg. configuration, so it should not be treated as a Base-model fitment. BFGoodrich, Nitto, and Pro-Trac options are available here, including Blackwall, RWL, and Redline presentations across several tire series. This size is the right one to examine when the car has the 20-inch sport front wheel and the buyer wants to stay with that lower-profile, larger-diameter setup.
255/40R19 is a metric radial size that combines a 255-millimeter nominal section width with a 40-series profile on a 19-inch rim. For the 2011 Mercedes-Benz S600 w/Sport Pkg., this is the alternate front fitment when the car uses 19-inch sport wheels instead of the 20-inch package. Available tires include several BFGoodrich series along with Pro-Trac options, and sidewall choices extend beyond Blackwall to RWL and Redline. This size deserves attention when the car has the sport front wheel setup but not the 20-inch version, making wheel-diameter confirmation especially important.
275/35R20 is a metric radial size with a 275-millimeter nominal section width, a 35-series profile, and a 20-inch rim diameter. On the 2011 Mercedes-Benz S600, it is the rear counterpart to the 255/35R20 front size on the 20-inch Sport Package setup, so it belongs to a staggered pair rather than a stand-alone rear choice. BFGoodrich, Nitto, and Pro-Trac products are available, with Blackwall, RWL, and Redline sidewall treatments represented. It is the rear size to verify when the car is equipped with 20-inch sport wheels and the goal is to preserve that specific front-to-rear relationship.
275/40R19 is a metric radial size that uses a 275-millimeter nominal section width, a 40-series profile, and a 19-inch rim diameter. On the 2011 Mercedes-Benz S600 w/Sport Pkg., this size serves as the rear match to the 255/40R19 front fitment, keeping the sport-package staggered setup together on 19-inch wheels. Product selection includes BFGoodrich and Nitto choices, with Blackwall as the sidewall style shown in this size. It is the size to consider when the car runs the 19-inch sport rear wheel and needs the corresponding rear width rather than the 18-inch Base or 20-inch sport arrangement.
Sub-model fitment on the 2011 Mercedes-Benz S600 is not one-size-fits-all, because the Base setup and the w/Sport Pkg. setup use different staggered front and rear tire combinations. Checking the exact sub-model and confirming whether the car carries 18-inch, 19-inch, or 20-inch wheels is the key first step before comparing tire choices.

2011 Mercedes-Benz S600 Base Front
The 2011 Mercedes-Benz S600 Base Front uses the standard front fitment for the non-sport setup, paired with a different rear size to create the car's staggered arrangement. Tire selection here centers on matching the correct 18-inch front wheel while choosing among available radial series and sidewall presentations.
The 2011 Mercedes-Benz S600 Base Rear uses the wider rear companion size for the standard 18-inch wheel package. Choosing for this position is mainly about confirming the correct rear wheel setup and intended use, since product variety is more limited than in several of the front and sport-package sizes.
The 2011 Mercedes-Benz S600 w/Sport Pkg. Front uses one of two sport front sizes depending on whether the car has 19-inch or 20-inch wheels. That makes wheel-diameter confirmation especially important before selecting a tire, even though both choices remain radial sport-oriented fitments.
The 2011 Mercedes-Benz S600 w/Sport Pkg. Rear uses one of two wider rear sport sizes, matched to the corresponding 19-inch or 20-inch front setup. Tire choice here should keep the staggered package intact and account for the actual rear wheel diameter on the car before comparing brands or sidewall style.
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 questions for the 2011 Mercedes-Benz S600 usually come down to staggered front and rear sizing, 18-inch versus 19-inch or 20-inch wheel packages, and choosing among available radial tire series and sidewall styles. The FAQs below focus on exact fitment, wheel confirmation, product selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2011 Mercedes-Benz S600?
The 2011 Mercedes-Benz S600 uses staggered radial tire sizes, and the correct pair depends on the wheel package. Base fitment uses 255/45R18 in front and 275/45R18 in the rear. The w/Sport Pkg. setup uses either 255/40R19 and 275/40R19 or 255/35R20 and 275/35R20, again with separate front and rear sizes.
That means the first step is not choosing a brand but confirming whether the car is Base or w/Sport Pkg. and verifying the actual wheel diameter on the vehicle. A previous owner may have changed wheels, so matching the tire to the front and rear positions separately is important before comparing series, sidewall style, or other product details.
What size rim does a 2011 Mercedes-Benz S600 use?
A 2011 Mercedes-Benz S600 uses 18-inch, 19-inch, or 20-inch rims depending on the specific setup. The Base front and rear fitments are built around 18-inch wheels, while the w/Sport Pkg. fitments use either 19-inch or 20-inch wheels in staggered front and rear combinations.
Rim diameter should be confirmed before anything else because each listed tire size is tied to one of those wheel diameters. Wheel width also matters when comparing individual tire products, especially on a staggered luxury-performance car, so checking the actual wheel dimensions on the car helps avoid choosing a tire that matches the size code but not the wheel itself.
Why does the 2011 Mercedes-Benz S600 have more than one tire size?
The 2011 Mercedes-Benz S600 has more than one tire size because it uses staggered front and rear fitments, and those fitments change with the wheel package. Base models use one 18-inch front and rear pairing, while the w/Sport Pkg. uses different 19-inch or 20-inch front and rear pairings.
That combination means the car should be approached as a front-and-rear fitment problem rather than as a single tire-size search. Once the exact wheel package is confirmed, the remaining decision becomes comparing the available radial products in the correct size for each axle, including construction details, series differences, and sidewall treatments where those are offered.
Choosing the Right Tire
What should I consider when choosing a 2011 Mercedes-Benz S600 tire?
Start with the exact front or rear size and the wheel diameter already on the car, because the 2011 Mercedes-Benz S600 uses staggered radial fitments in 18-inch, 19-inch, and 20-inch configurations. From there, compare product series, sidewall style, and wheel-width compatibility within the correct size rather than trying to treat all S600 tires as interchangeable.
The best choice depends on how the car is used and how closely the tire should match the vehicle's overall presentation. A standard Base setup, a sport-wheel car, and a custom appearance goal can all point toward different products even within the same size, so confirm wheel specs first and then narrow the decision by brand, series, and sidewall treatment.
What sidewall styles are available for 2011 Mercedes-Benz S600 tires?
Sidewall style depends on the tire size. Blackwall appears across all of the S600 fitments shown here, while RWL and Redline options appear in selected front and rear sport and standard sizes through the Pro-Trac Street Pro III line. That gives some owners the option to move beyond a plain modern black sidewall presentation.
Appearance choice should still come after correct fitment. On a 2011 Mercedes-Benz S600, the right front and rear sizes and wheel diameters matter first, then the sidewall style can be used to shape the car's look. A more traditional or custom-oriented presentation may lead toward RWL or Redline, while Blackwall keeps the visual treatment more understated.
What brands offer tires for the 2011 Mercedes-Benz S600?
Tires for the 2011 Mercedes-Benz S600 are available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on the exact size. Brand availability is not identical across all six fitments, so the front and rear positions or the standard and sport wheel packages may open up different product choices.
Brand is only one part of the decision. A BFGoodrich g-Force series tire, a Nitto NT555 G2, a Pro-Trac Street Pro III, or an M&H Racemaster product can represent very different tire character and presentation even when the size is correct, so compare the actual size-specific options before deciding what belongs on the car.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Mercedes-Benz S600?
A period-style 2011 Mercedes-Benz S600 tire choice usually starts by keeping the car in its proper front and rear size pair and in the wheel diameter it actually uses. Since every primary fitment here is radial, the appearance decision comes from the specific product series and sidewall treatment rather than from choosing between vintage bias-ply and radial construction.
For a more restrained luxury-sedan presentation, Blackwall keeps the look close to a contemporary factory-era theme. RWL or Redline can shift the car toward a more personalized appearance, but exact originality should be checked against marque-specific references and the car's own equipment history if that level of detail matters to the build.
How does tire construction affect the appearance of a restored 2011 Mercedes-Benz S600?
On a 2011 Mercedes-Benz S600, construction changes the look less dramatically than on an earlier collector car because the primary fitments are already modern radial tires. The visible appearance difference comes more from sidewall style, tread presentation, and maintaining the proper staggered proportions than from switching between fundamentally different construction types.
That makes size accuracy especially important to the finished look. A front tire that is too wide, a rear tire that does not match the intended stagger, or a wheel diameter that differs from the actual setup can change the car's stance more than the brand name on the sidewall, so appearance goals should follow exact fitment confirmation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Mercedes-Benz S600?
Yes. Modifications can affect tire fitment on a 2011 Mercedes-Benz S600, especially because the car already uses staggered front and rear sizing and may be equipped with 18-inch, 19-inch, or 20-inch wheels. Aftermarket wheels, offset changes, suspension lowering, or body and brake changes can alter the clearances that the original size package depends on.
That makes it important to verify the actual wheel diameter and width on the car before choosing tires, then check steering and fender clearance once the correct size pair is selected. Even when a tire matches the nominal size code, the overall setup should still be reviewed if the car no longer sits on its original wheel and suspension configuration.
What should I inspect before driving a 2011 Mercedes-Benz S600 on new tires?
Before driving a 2011 Mercedes-Benz S600 on new tires, inspect wheel condition, confirm that the front and rear sizes match the actual wheel package, and check inflation carefully. It also helps to look over suspension components, alignment condition, and brake or fender clearances so the new tires begin service on a sound chassis.
A short initial road test is a smart next step. Listen for rubbing, feel for vibration, and recheck pressure after the first miles, especially on a staggered setup with lower-profile sport sizes. On a heavy luxury-performance sedan, small fitment issues become noticeable quickly, so catching them early helps protect both the tires and the wheels.
How should tires on a 2011 Mercedes-Benz S600 be maintained?
Tires on a 2011 Mercedes-Benz S600 should be maintained with regular pressure checks, visual inspection for cuts, bulges, or sidewall cracking, and close attention to tread wear across both axles. Because the car uses staggered sizing, front and rear tires should be monitored as separate fitments rather than assumed to wear or behave the same way.
Storage habits matter too, especially on a low-mileage car that may sit for long periods. Keeping the S600 away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, while periodic inspections help catch age-related issues before road use. Any sign of repeated air loss, uneven wear, or clearance contact deserves prompt correction.
