The 2017 Mercedes-Benz S550e blends full-size S-Class luxury with plug-in hybrid efficiency, so tire fitment needs to support both the car’s substantial presence and its refined road manners. On this model, the key decision is not simply brand selection but confirming whether the car is on the 19-inch or 20-inch wheel setup, because front and rear sizes are staggered. The front uses either 245/45R19 or 245/40R20, while the rear uses either 275/40R19 or 275/35R20, all in radial construction. Available choices include blackwall, raised white letter, and redline sidewall treatments across several performance-oriented series. Getting the right combination starts with matching the exact front and rear fitment already on the car.
Which Tire Size Is Right for The 2017 Mercedes-Benz S550e
The 2017 Mercedes-Benz S550e uses four primary tire sizes because fitment is staggered front to rear and also varies by wheel diameter. The first step is confirming whether the car has the 19-inch or 20-inch setup, since the front and rear sizes must stay properly matched. Once wheel diameter is verified, the real comparison becomes tire series, sidewall style, and the character of the available radial options.
A 245/40R20 tire is a metric radial size with a 245-millimeter section width, a 40-series aspect ratio, and a 20-inch rim diameter. On the 2017 Mercedes-Benz S550e, this is one of the front tire sizes used with the 20-inch staggered setup, so it needs to be paired with the corresponding 20-inch rear size rather than mixed with the 19-inch package. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, raised white letter, and redline sidewall treatments. This size makes the most sense when the car is already equipped with 20-inch front wheels and the owner wants to compare appearance and tire-series differences within that setup.
A 245/45R19 tire uses the same 245-millimeter nominal width as the 20-inch front size, but with a 45-series profile and a 19-inch rim diameter. For the 2017 Mercedes-Benz S550e, it serves as the front tire size on the 19-inch staggered arrangement, so it belongs with the matching 19-inch rear fitment. BFGoodrich and Nitto options are available in this size, primarily in blackwall form across g-Force and NT555 G2 series. This is the size to evaluate when the car has 19-inch front wheels and the goal is staying within the correct front fitment while comparing product character.
A 275/35R20 tire is a wider metric radial size with a 275-millimeter section width, a 35-series profile, and a 20-inch rim diameter. On the 2017 Mercedes-Benz S550e, this size is used at the rear with the 20-inch staggered wheel package, so it works as part of a front-to-rear matched combination rather than as a stand-alone choice. Available products include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall styles. This rear size should be considered when confirming a complete 20-inch setup and comparing how different tire series support the look and use of the car.
A 275/40R19 tire keeps the same nominal 275-millimeter rear width but uses a 40-series profile on a 19-inch rim. For the 2017 Mercedes-Benz S550e, this is the rear size paired with the 19-inch front fitment, making it part of the 19-inch staggered package rather than an all-purpose rear substitute. BFGoodrich and Nitto choices are available here, with blackwall sidewalls and several g-Force and NT555 G2 series options. This size is the right place to focus when the car is on 19-inch rear wheels and the buyer wants to compare series, load-related specs, and rim-width compatibility.
Sub-model fitment on the 2017 Mercedes-Benz S550e is straightforward once the car is understood as a staggered front-and-rear setup. Checking whether a tire is for the front or rear position matters just as much as confirming whether the car uses the 19-inch or 20-inch wheel package.

2017 Mercedes-Benz S550e Base Front
The 2017 Mercedes-Benz S550e Base Front uses one of two front radial sizes, depending on whether the car is equipped with 19-inch or 20-inch wheels. Tire selection here starts with wheel-diameter confirmation, then moves to comparing blackwall or specialty sidewall treatments and the available performance-oriented series.
The 2017 Mercedes-Benz S550e Base Rear uses one of two wider rear radial sizes that correspond to the same 19-inch or 20-inch package as the front. Choosing the rear tire means preserving the correct staggered combination and verifying that the selected tire matches the wheel diameter already on the car.
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 Size & Fitment
What tire size fits a 2017 Mercedes-Benz S550e?
The 2017 Mercedes-Benz S550e uses a staggered radial tire setup rather than one universal size. Front fitment is either 245/45R19 or 245/40R20, and rear fitment is either 275/40R19 or 275/35R20, depending on which wheel package is on the car.
That means tire selection starts with confirming both wheel diameter and axle position. A front size should stay paired with the corresponding rear size from the same 19-inch or 20-inch setup, and any car with replacement wheels should be checked carefully before choosing tires.
What size rim does a 2017 Mercedes-Benz S550e use?
A 2017 Mercedes-Benz S550e uses either 19-inch or 20-inch rims, depending on the setup on the car. The 19-inch package uses 245/45R19 front and 275/40R19 rear tires, while the 20-inch package uses 245/40R20 front and 275/35R20 rear tires.
Rim diameter is the first thing to verify because the tire sizes are tied directly to it. Looking at the existing tire sidewall and confirming the actual wheel size on both axles helps prevent mixing 19-inch and 20-inch fitments or ordering a front and rear combination that does not belong together.
Why does the 2017 Mercedes-Benz S550e have more than one tire size?
The 2017 Mercedes-Benz S550e has more than one tire size because it uses a staggered arrangement, with narrower tires in front and wider tires in back, and it was fitted with either a 19-inch or 20-inch wheel package. That creates four primary sizes across the complete vehicle fitment.
The practical takeaway is that the car does not have a single all-around tire size. Matching the correct front and rear pair matters, and the buyer should confirm wheel diameter first so the chosen tires maintain the intended staggered relationship already built into the setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Mercedes-Benz S550e?
Start with the basics: confirm whether the car has 19-inch or 20-inch wheels, then verify whether the tire is for the front or rear position. The 2017 Mercedes-Benz S550e uses staggered radial sizing, so correct axle placement and wheel diameter matter before brand or series comparisons begin.
Once fitment is confirmed, compare the available tire series, sidewall presentation, and rim-width compatibility where stated. Buyers also benefit from checking load-related specifications, intended driving use, and whether the car still has its original wheel setup or has been changed with aftermarket wheels.
What sidewall styles are available for 2017 Mercedes-Benz S550e tires?
Sidewall choice depends on size, but the 2017 Mercedes-Benz S550e has blackwall options throughout its fitments. Select 20-inch sizes also offer raised white letter and redline sidewall treatments through Pro-Trac Street Pro III, giving the car a more customized visual presentation than a standard blackwall tire.
That makes sidewall style a meaningful appearance decision once the correct size is established. A blackwall tire keeps the look restrained and contemporary, while redline or raised white letter changes the character noticeably, so owners should choose the presentation that suits the car’s wheel design and overall look.
What brands offer tires for the 2017 Mercedes-Benz S550e?
Tires for the 2017 Mercedes-Benz S550e are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. Across the four fitments, the main series include BFGoodrich g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice should be treated as one part of the decision, not the whole decision. The better approach is to compare the correct size first, then look at sidewall style, series character, rim-width compatibility, and any stated load specification so the tire matches both the wheel package and the way the car is used.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Mercedes-Benz S550e?
A period-style choice for a 2017 Mercedes-Benz S550e starts with staying in the proper staggered 19-inch or 20-inch fitment rather than changing the car’s basic sizing. Since this is a modern luxury sedan, blackwall radial tires are the most natural visual starting point across the available selections.
Appearance still leaves room for preference, especially on the 20-inch setup where specialty sidewalls are available. Owners who want the car to retain a more understated original-era presence will usually focus on the correct front and rear sizes first, then choose a tread and sidewall treatment that does not overpower the car’s styling.
How does tire construction affect the appearance of a restored 2017 Mercedes-Benz S550e?
On a 2017 Mercedes-Benz S550e, construction is straightforward because the primary fitments are radial tires across all four sizes. That means the appearance decision is shaped less by bias-ply versus radial questions and more by sidewall treatment, tire series, and whether the car is on 19-inch or 20-inch wheels.
A blackwall radial keeps the visual presentation closest to the restrained look most buyers expect on a late-model S-Class. Redline or raised white letter sidewalls can create a more customized impression, so owners aiming for a restoration-oriented result should consider how strongly the sidewall style changes the car’s overall presence.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz S550e?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz S550e, especially because the car already uses a staggered setup with two possible wheel diameters. Aftermarket wheels, suspension changes, altered ride height, or spacer use can change clearance, wheel-width suitability, and the relationship between the front and rear tire package.
Any S550e with changes from stock should be checked closely before replacing tires. Wheel diameter, wheel width, and available clearance at steering lock and suspension travel all matter, and those checks become more important when matching wider rear tires to a modified wheel or suspension setup.
What should I inspect before driving a 2017 Mercedes-Benz S550e on new tires?
Before driving a 2017 Mercedes-Benz S550e on new tires, confirm that the front and rear sizes match the wheel package on the car and that all four tires are seated correctly on the rims. Tire pressure, valve condition, balance, visible sidewall damage, and any sign of rubbing should be checked before regular road use.
A short initial drive followed by a second inspection is a practical habit on a staggered setup. Rechecking pressure, looking for clearance issues, and confirming that the car tracks properly helps catch installation or fitment problems early, especially if the vehicle has non-original wheels or recent suspension work.
What should I check before a longer drive in a 2017 Mercedes-Benz S550e?
Before a longer drive, a 2017 Mercedes-Benz S550e should have its tire pressures checked cold, along with tread condition, air retention, and any visible cracking, cuts, or bulges. On a staggered setup, it is also smart to confirm that the front and rear tire sizes are still correctly matched to the wheel diameters on the car.
Longer trips put more emphasis on consistency and condition than casual local use. Owners should also look for uneven wear, listen for vibration during the first miles, and inspect the wheels for damage, since a low-profile 19-inch or 20-inch tire package can be more sensitive to wheel issues and previous impact damage.
