The 2017 Mercedes-Benz S63 AMG blends full-size S-Class luxury with the kind of power and road presence expected from AMG’s hand-built performance sedans and coupes. It is a modern high-performance car, but one where tire fitment still needs to be approached carefully because the setup is staggered rather than square. This 2017 Mercedes-Benz S63 AMG uses a 255/40R20 radial tire in front and a 285/35R20 radial tire in the rear. Available choices include Blackwall, raised white letter, and Redline sidewall treatments across several radial performance series. The key is matching the correct front and rear sizes while confirming the car still has its intended 20-inch wheel setup.
Which Tire Size Is Right for The 2017 Mercedes-Benz S63 AMG
The 2017 Mercedes-Benz S63 AMG uses two primary tire sizes, with one size assigned to the front and a larger size assigned to the rear. Both are radial fitments on 20-inch wheels, so the first step is confirming whether you are replacing the front tires, the rear tires, or a complete staggered set. Once that is clear, the decision shifts to brand, tire series, sidewall style, and wheel-width compatibility.
255/40R20 is a metric radial size in which 255 identifies the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2017 Mercedes-Benz S63 AMG, this is the front tire size, so it needs to be treated as part of the car’s staggered setup rather than as a universal fitment for all four corners. BFGoodrich offers this size in the g-Force Phenom T/A series with a Blackwall sidewall. Choosing this size correctly matters because front tire dimensions influence steering response, clearance, and the overall balance of the staggered package.
285/35R20 is a metric radial size where 285 gives the nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 20 identifies the wheel diameter in inches. On the 2017 Mercedes-Benz S63 AMG, this is the rear tire size, making it the wider half of the factory-style staggered arrangement. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with Blackwall, RWL, and Redline sidewall styles represented across g-Force, NT555 G2, and Street Pro III series. This is the size to evaluate when rear traction, appearance, and wheel-width compatibility are the main concerns.
Fitment on the 2017 Mercedes-Benz S63 AMG is straightforward once front and rear positions are separated correctly. The important distinction is not trim variation, but the staggered layout, since the front and rear use different radial tire sizes on the same 20-inch wheel diameter.

2017 Mercedes-Benz S63 AMG Base Front
The Base Front position uses the smaller of the two primary tire sizes and sets the steering end of the staggered package. Tire selection here centers on keeping the correct front size, confirming wheel width, and matching the intended appearance and performance character of the rest of the set.
The Base Rear position uses the wider rear tire size that completes the staggered layout of the 2017 Mercedes-Benz S63 AMG. Choosing for this position means comparing rear-specific options by brand, series, and sidewall style while making sure the tire suits the wheel and overall front-to-rear setup.
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 S63 AMG?
The 2017 Mercedes-Benz S63 AMG uses a staggered tire setup with 255/40R20 in the front and 285/35R20 in the rear. Both are radial tire sizes, and both are built for 20-inch wheels, but they are not the same size at all four corners.
That means the first step is identifying which axle needs replacement. A front tire selection should stay with 255/40R20, while the rear should stay with 285/35R20 unless the car has been changed from its intended wheel and tire arrangement. Checking the actual wheel sizes on the car is especially important if it has aftermarket wheels or previous owner modifications.
What size rim does a 2017 Mercedes-Benz S63 AMG use?
The 2017 Mercedes-Benz S63 AMG uses 20-inch rims with both of its primary tire sizes. The front 255/40R20 and the rear 285/35R20 share the same wheel diameter, even though the rear tire is wider and uses a different aspect ratio.
Wheel diameter is only part of the fitment picture, so it is still wise to confirm the wheel width before choosing a replacement tire. One available 255/40R20 product is suited to 8.5 to 10-inch rims, and one available 285/35R20 product is suited to 9.5 to 11.0-inch rims, which shows how width compatibility matters on a staggered performance car.
Why does the 2017 Mercedes-Benz S63 AMG have more than one tire size?
The 2017 Mercedes-Benz S63 AMG has more than one tire size because it uses a staggered fitment. The front position takes 255/40R20, while the rear position takes 285/35R20, giving the car different tire dimensions at each end instead of a square four-corner setup.
For the buyer, that changes the replacement process. Front and rear tires should be matched to their intended positions, and any full set should be chosen with the staggered layout in mind. A mismatch in size, wheel width, or tire type can alter clearance and upset the balanced look and road manners expected from a modern AMG performance luxury car.
Choosing the Right Tire
What should I consider when choosing a 255/40R20 or 285/35R20 tire for a 2017 Mercedes-Benz S63 AMG?
Start with the correct axle position, since the 2017 Mercedes-Benz S63 AMG uses 255/40R20 in front and 285/35R20 in the rear. From there, compare radial tire series, wheel-width suitability, sidewall style, and product characteristics that fit how the car is actually used.
A careful choice balances fitment with the look you want from the car. Some owners will prioritize a clean Blackwall performance presentation, while others may want a more distinctive sidewall treatment at the rear. It also helps to check load information, overall tire construction, and whether the car still has its intended wheel setup before making a final selection.
What sidewall styles are available for 2017 Mercedes-Benz S63 AMG tires?
Sidewall style depends on the tire size and product chosen. Blackwall is available in both the 255/40R20 front size and the 285/35R20 rear size, while the 285/35R20 rear fitment also includes RWL and Redline options in the Pro-Trac Street Pro III series.
That gives the S63 AMG owner a meaningful appearance choice, especially if the goal is something more distinctive than a conventional black sidewall. The practical step is making sure the sidewall treatment is tied to the correct rear size and tire series, rather than selecting on looks alone and overlooking wheel compatibility or the car’s staggered front-to-rear setup.
What brands offer tires for the 2017 Mercedes-Benz S63 AMG?
Available tires for the 2017 Mercedes-Benz S63 AMG come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both front and rear sizes, while Nitto and Pro-Trac are represented in the 285/35R20 rear size.
Brand is only one part of the decision, so it helps to compare by tire series and sidewall treatment at the same time. BFGoodrich covers g-Force Phenom T/A and g-Force Comp 2 AS offerings, Nitto brings the NT555 G2, and Pro-Trac offers Street Pro III choices with alternate sidewall looks for buyers who want more visual character at the rear.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Mercedes-Benz S63 AMG?
A period-style approach on a 2017 Mercedes-Benz S63 AMG usually means staying with the original-type staggered radial sizing of 255/40R20 in front and 285/35R20 in the rear, then choosing a tire whose overall appearance suits the car’s modern AMG character. Blackwall options keep the presentation closest to contemporary performance luxury styling.
The decision becomes more visual once the correct sizes are established. A buyer looking for a cleaner, understated look may lean toward Blackwall, while someone building a more personalized appearance may consider rear options with RWL or Redline. The car’s wheel design and overall finish should guide that choice so the tires complement, rather than overpower, the S63 AMG’s design.
How does tire construction affect the appearance of a restored 2017 Mercedes-Benz S63 AMG?
On the 2017 Mercedes-Benz S63 AMG, construction is straightforward because the primary fitment is radial at both the front and rear. The visual difference comes less from bias-ply versus radial, and more from the specific tire series, sidewall treatment, and how the tire fills the wheel opening within the correct staggered sizing.
For a restoration-minded or preservation-focused owner, keeping the proper 255/40R20 front and 285/35R20 rear layout matters more than chasing novelty. A conventional Blackwall presentation tends to look more in step with the car’s era, while RWL or Redline can create a more customized effect. Wheel condition, ride height, and stance all influence how the finished setup will look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz S63 AMG?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz S63 AMG even when the tire sizes remain 255/40R20 in front and 285/35R20 in the rear. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change clearance and wheel-width requirements.
A car that still wears its intended 20-inch setup is simpler to match, but any changes deserve a closer look before replacing tires. It is smart to verify wheel width, check inner and outer clearance at full steering lock, and make sure the staggered arrangement has not been altered to a nonstandard combination by a previous owner.
What should I inspect before driving a 2017 Mercedes-Benz S63 AMG on new tires?
Before driving a 2017 Mercedes-Benz S63 AMG on new tires, inspect the wheels for damage, confirm the front and rear sizes are mounted in the correct positions, and check inflation pressure carefully. It also helps to look over the suspension and alignment condition so the new tires are not compromised early.
A high-performance luxury car can feel sensitive to setup issues that might be less noticeable on a lower-powered vehicle. Uneven wear, vibration, or steering pull can point to wheel, alignment, or suspension problems rather than a tire defect. A short recheck after initial road use is worthwhile to confirm pressures remain stable and there is no rubbing.
How often should tires on a 2017 Mercedes-Benz S63 AMG be inspected?
Tires on a 2017 Mercedes-Benz S63 AMG should be inspected regularly, especially because the car uses a staggered setup that prevents simple front-to-rear rotation in the usual sense. Pressure, tread wear, sidewall condition, and any signs of impact damage all deserve routine attention.
Inspection matters even more if the car sees limited use or spends long stretches parked. Performance tires can age out before they wear out, so it is wise to watch for cracking, bulges, flat spotting, or gradual air loss. Checking the tires before a longer drive is a practical habit, particularly on a heavy, powerful car riding on low-profile 20-inch radials.
