The 2015 Mercedes-Benz S600 sits at the top of the modern S-Class range, blending long-wheelbase luxury with the effortless power and road presence expected of a flagship Mercedes sedan. Buyers looking at this car usually care as much about composed highway behavior and proper stance as they do outright performance. Tire fitment centers on a staggered radial setup, with 245-section front sizes and wider 275-section rear sizes, offered in either 19-inch or 20-inch wheel diameters. That means the real decision is not just size, but matching the correct front and rear combination, wheel diameter, and sidewall treatment to the car's current setup and intended look.
Which Tire Size Is Right for The 2015 Mercedes-Benz S600
The 2015 Mercedes-Benz S600 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 wheel diameter and whether you are selecting for the front or rear axle, since the car uses a staggered radial arrangement rather than one universal size at all four corners.
245/40R20 is a metric radial size in which 245 represents section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2015 Mercedes-Benz S600, this size serves the front position when the car is equipped with the 20-inch wheel setup. Available choices include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, raised white letter, and Redline sidewall treatments depending on the tire series. This size is worth evaluating carefully if the car already wears 20-inch front wheels and you want to balance modern performance character with the sidewall appearance that suits the car best.
245/45R19 is a metric radial size with a 245-millimeter section width, a 45-series profile, radial construction, and a 19-inch rim diameter. On the 2015 Mercedes-Benz S600, this is the front tire size used with the 19-inch wheel package rather than the 20-inch setup. BFGoodrich and Nitto offerings appear in this size, largely in Blackwall form and across different g-Force and NT555 G2 series. This size becomes the right choice when the sedan retains its 19-inch front wheels and you want to stay aligned with the proper front fitment for that wheel diameter.
275/35R20 is a metric radial size where 275 is the nominal section width in millimeters, 35 is the aspect ratio, R means radial, and 20 is the wheel diameter. On the 2015 Mercedes-Benz S600, this wider size belongs at the rear when the car is fitted with the 20-inch staggered package. Product choices include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, raised white letter, and Redline sidewall treatments represented among the available series. This is the size to compare when confirming a 20-inch rear fitment and selecting the look and tire character that best matches the sedan's stance and current wheel package.
275/40R19 is a metric radial size that uses a 275-millimeter section width, 40-series profile, radial construction, and a 19-inch rim diameter. For the 2015 Mercedes-Benz S600, this size is used at the rear with the 19-inch staggered setup, pairing with a narrower 19-inch front tire rather than the 20-inch combination. BFGoodrich and Nitto options are available here, including several g-Force series and Blackwall sidewall presentations. This rear size should be chosen only after confirming that the car is on 19-inch wheels and that the front and rear pair remain matched as a proper staggered set.
Sub-model fitment on the 2015 Mercedes-Benz S600 is straightforward in one sense and critical in another: the car uses dedicated front and rear sizes rather than one tire size all around. Checking whether you are replacing front or rear tires, and whether the car has 19-inch or 20-inch wheels, matters before any tire is selected.

2015 Mercedes-Benz S600 Base Front
The 2015 Mercedes-Benz S600 Base Front uses a narrower front radial tire, with fitment split between a 19-inch and a 20-inch wheel package. Tire selection at the front is mainly about confirming wheel diameter first, then choosing among the available brands, series, and sidewall treatments that suit the car's current setup.
The 2015 Mercedes-Benz S600 Base Rear uses the wider rear half of the staggered radial combination, again divided between 19-inch and 20-inch wheel diameters. Rear tire selection should keep that staggered arrangement intact, while also accounting for the available series and sidewall styles that shape the car's finished appearance.
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 2015 Mercedes-Benz S600 usually need clarity on staggered tire sizing, front-versus-rear fitment, 19-inch versus 20-inch wheels, and how sidewall style or tire series affects the final choice. These answers focus on those exact issues, along with maintenance and road-use checks.
Tire Size & Fitment
What tire size fits a 2015 Mercedes-Benz S600?
The 2015 Mercedes-Benz S600 uses a staggered radial setup rather than one tire 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 which wheel package is on the car.
That means the first step is identifying both wheel diameter and axle position before choosing tires. A front size should stay with the matching rear size for the same 19-inch or 20-inch setup, and any car with changed wheels should have actual wheel dimensions and clearances checked before replacement.
What size rim does a 2015 Mercedes-Benz S600 use?
The 2015 Mercedes-Benz S600 uses either 19-inch or 20-inch rims. The 19-inch package pairs 245/45R19 front tires with 275/40R19 rear tires, while the 20-inch package pairs 245/40R20 front tires with 275/35R20 rear tires.
Rim diameter is the quickest way to narrow the correct tire size for this car, but it is not the only check. Front and rear widths are different on a staggered setup, so replacement tires should match both the wheel diameter and the correct axle position rather than being selected by diameter alone.
Why does the 2015 Mercedes-Benz S600 have more than one tire size?
Multiple tire sizes appear on the 2015 Mercedes-Benz S600 because the car uses a staggered arrangement with narrower front tires and wider rear tires, and because it was fitted with either a 19-inch or 20-inch wheel package. That creates two matched front-and-rear combinations instead of one universal size.
The practical takeaway is that tire selection starts with the car's actual wheel package, not the model name alone. Looking at the existing tire sidewalls or measuring wheel diameter helps avoid mixing a 19-inch front with a 20-inch rear fitment or pairing the wrong rear size with the correct front size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Mercedes-Benz S600?
Start with the basics that matter most on this car: front or rear position, 19-inch or 20-inch wheel diameter, and the correct staggered size for that setup. From there, compare the available radial tire series, sidewall style, and wheel-width compatibility where those specifications are given.
A buyer focused on a clean modern look may stay with Blackwall, while someone wanting more visual distinction may consider raised white letter or Redline options in certain 20-inch sizes. It also helps to compare load figures and intended use, especially on a large luxury-performance sedan that should keep balanced front and rear fitment.
What sidewall styles are available for 2015 Mercedes-Benz S600 tires?
Sidewall choices for the 2015 Mercedes-Benz S600 include Blackwall across all four primary sizes, with raised white letter and Redline treatments appearing in the 20-inch sizes. Those appearance options are tied to specific tire series rather than being available in every size and brand combination.
That makes sidewall style a secondary choice after fitment is confirmed. Owners staying close to the sedan's understated luxury presentation often prefer Blackwall, while raised white letter or Redline can add a more custom or sport-oriented visual accent, particularly if the car already carries a personalized wheel and tire look.
What brands offer tires for the 2015 Mercedes-Benz S600?
Tires for the 2015 Mercedes-Benz S600 are available from BFGoodrich, Nitto, and Pro-Trac, depending on the exact size. BFGoodrich appears across all four fitments, Nitto is also represented in each main size, and Pro-Trac options are present in the 20-inch front and rear sizes.
Brand selection should be weighed alongside tire series, sidewall treatment, and the actual wheel package on the car. Since this S600 uses a staggered setup, the goal is not just finding a preferred brand, but making sure the chosen front and rear sizes remain properly matched for the same 19-inch or 20-inch combination.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Mercedes-Benz S600?
A period-style approach on a 2015 Mercedes-Benz S600 usually starts with preserving the correct staggered sizing and the proper 19-inch or 20-inch wheel package already on the car. Since all primary fitments are modern radials, the visual decision tends to center more on sidewall presentation and tire series than on vintage-style construction.
Blackwall is the most understated choice and generally keeps the large Mercedes sedan looking closest to its original design era, while certain 20-inch sizes also allow more expressive raised white letter or Redline treatments. Buyers pursuing exact originality should compare their car against window-sticker, dealer, or marque-specific references before deciding on appearance details.
Does correct tire fitment matter for a 2015 Mercedes-Benz S600 restoration?
Correct tire fitment matters on a 2015 Mercedes-Benz S600 because the car's stance, wheel-to-fender balance, and front-to-rear proportion all depend on keeping the intended staggered relationship intact. Even on a newer collector-oriented sedan, the wrong axle pairing or wrong wheel diameter can change the car's visual balance immediately.
Using the proper front and rear sizes for the wheel package already on the car helps preserve both appearance and fitment discipline. That is especially important if the vehicle has had wheel changes over time, since a restoration-minded owner should confirm actual wheel dimensions instead of assuming every S600 uses the same combination.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Mercedes-Benz S600?
Yes, modifications can affect tire fitment on a 2015 Mercedes-Benz S600, especially because the car already uses a staggered setup with different front and rear sizes. Aftermarket wheels, suspension changes, lowering, or body alterations can change the clearance relationship that the original 19-inch or 20-inch tire combinations were built around.
That makes it wise to verify actual wheel diameter and width before replacing tires on a modified car. Steering clearance at the front, fender clearance at both ends, and rear fitment under load all deserve attention so the selected tire size still works with the vehicle's current configuration.
What should I inspect before driving a 2015 Mercedes-Benz S600 on new tires?
Before road use, inspect the 2015 Mercedes-Benz S600 for correct front and rear tire placement, proper inflation, valve-stem condition, and even seating on the wheels. A quick visual check for rubbing marks, sidewall contact, or unusual suspension clearance is especially important on a staggered luxury sedan with wide rear tires.
A short, careful test drive can reveal vibration, pulling, or interference that is not obvious while the car is parked. Rechecking pressure after installation and confirming the tires match the intended 19-inch or 20-inch front-and-rear combination helps catch setup errors before the car is driven at normal highway speeds.
How often should tires on a 2015 Mercedes-Benz S600 be inspected?
Tires on a 2015 Mercedes-Benz S600 should be inspected regularly, with a quick visual check before routine use and a more careful inspection at intervals throughout the driving season. On a low-mileage or collector-kept example, aging and condition can matter just as much as tread depth.
Pay attention to air loss, uneven wear between front and rear positions, sidewall cracking, cuts, bulges, and any signs of contact inside the wheelhouse. Since the car uses staggered sizes, tire rotation patterns are limited, so catching wear early helps prevent a front or rear pair from being replaced unexpectedly.
