The 2019 Mercedes-Benz S65 AMG sits at the far end of the modern grand-touring luxury spectrum, combining full-size S-Class refinement with the harder-edged character expected from an AMG flagship. That mix of weight, power, and high-speed road manners makes correct staggered tire fitment especially important. This model uses a 255/40R20 radial in front and a 285/35R20 radial in the rear, both on 20-inch rims. Available choices include blackwall performance tires along with raised white letter and redline rear options in selected series. For this car, the main decision is matching the correct front and rear sizes while choosing the appearance and tire series that suit your intended use.
Which Tire Size Is Right for The 2019 Mercedes-Benz S65 AMG
The 2019 Mercedes-Benz S65 AMG uses two primary tire sizes, with a staggered radial setup that places one size on the front axle and a wider size on the rear, both on 20-inch rims. The first step is confirming whether you are selecting a front or rear tire, because the two positions do not use the same size and should not be treated interchangeably.
255/40R20 is a metric radial size in which 255 identifies the nominal section width in millimeters, 40 is the aspect ratio, and 20 is the rim diameter in inches. On the 2019 Mercedes-Benz S65 AMG, this size serves the front position and supports the car's staggered performance-oriented setup. Available options in this size include a BFGoodrich g-Force Phenom T/A blackwall radial. This is the size to evaluate when replacing the front tires and when confirming wheel width, tire series, and overall compatibility with the car's existing front-end setup.
285/35R20 is a wider metric radial size, with 285 denoting nominal section width in millimeters, 35 indicating the aspect ratio, and 20 identifying the rim diameter. On the 2019 Mercedes-Benz S65 AMG, this size is used at the rear, where the staggered fitment calls for a broader tire than the front. Choices in this size include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, raised white letter, and redline sidewall treatments available. This rear size matters when preserving the intended front-to-rear balance and selecting the appearance or tire series that best suits the car.
Fitment stays consistent in size by axle position across the covered S65 AMG body styles, with the same front and rear tire sizes used on both coupe/cabriolet and sedan applications. Checking the exact sub-model still matters so the correct axle position is matched before selecting a tire.

2019 Mercedes-Benz S65 AMG Coupe & Cabriolet Front
The 2019 Mercedes-Benz S65 AMG Coupe & Cabriolet Front uses the front half of the staggered setup, with a 20-inch radial fitment specific to that axle position. Tire selection here centers on maintaining the proper front size and confirming wheel-width compatibility before comparing available series or sidewall presentation.
The 2019 Mercedes-Benz S65 AMG Coupe & Cabriolet Rear uses the wider rear portion of the staggered 20-inch radial combination. Choosing this position correctly is important because the rear tire lineup includes the broadest variety of brands, tire series, and sidewall styles for this vehicle.
The 2019 Mercedes-Benz S65 AMG Sedan Front follows the same front tire fitment used on the coupe and cabriolet versions, keeping axle-specific sizing consistent across body styles. The key decision is selecting the correct front size first, then comparing available product characteristics within that fitment.
The 2019 Mercedes-Benz S65 AMG Sedan Rear uses the same wider rear tire size found on the coupe and cabriolet rear applications. That gives sedan owners the same need to confirm rear-wheel fitment and the same opportunity to compare blackwall, raised white letter, or redline presentation.
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 2019 Mercedes-Benz S65 AMG?
The 2019 Mercedes-Benz S65 AMG uses a staggered tire setup with 255/40R20 on the front and 285/35R20 on the rear. Both are radial tire sizes mounted on 20-inch rims, so this car does not use the same size at all four corners.
That staggered arrangement makes axle position the first thing to confirm before choosing a tire. A front replacement should stay within the front size, and a rear replacement should stay within the rear size, while wheel width, tire series, and any prior wheel changes should also be checked before installation.
What size rim does a 2019 Mercedes-Benz S65 AMG use?
The 2019 Mercedes-Benz S65 AMG uses 20-inch rims with both of its primary tire sizes. The front 255/40R20 and rear 285/35R20 share the same rim diameter even though the rear tire is wider and lower in profile.
Matching rim diameter alone is not the whole fitment decision, because wheel width also matters on a staggered setup. A 20-inch wheel that is too narrow or too wide for the intended tire can create mounting and clearance issues, so the actual wheel dimensions should be confirmed before selecting a replacement.
Do all 2019 Mercedes-Benz S65 AMG sub-models use the same tire size?
The covered 2019 Mercedes-Benz S65 AMG sub-models share the same axle-based tire sizing. Coupe, cabriolet, and sedan applications all use 255/40R20 in front and 285/35R20 in the rear rather than different sizes by body style.
The practical point is that fitment stays consistent across these versions, but front and rear positions still need to be treated separately. A buyer should confirm which axle the tire is for and verify that the car still retains the proper staggered wheel and tire arrangement if any wheel changes have been made.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Mercedes-Benz S65 AMG?
Start with the correct axle-specific size, since the 2019 Mercedes-Benz S65 AMG uses 255/40R20 in front and 285/35R20 in the rear. After that, compare radial tire series, sidewall style, rim-width compatibility where stated, and product characteristics that match how the car is actually driven.
A useful way to narrow the choice is to decide whether appearance, brand preference, or a particular tire series matters most. Blackwall options keep a contemporary look, while rear choices in raised white letter or redline shift the visual character, and wheel dimensions should always be checked before final selection.
What sidewall styles are available for 2019 Mercedes-Benz S65 AMG tires?
Sidewall choices for the 2019 Mercedes-Benz S65 AMG include blackwall, raised white letter, and redline, depending on tire size and product series. Blackwall is available in both the front and rear fitments, while the rear 285/35R20 size adds the wider appearance choices.
That means the rear axle gives the most room to shape the car's visual presentation without changing the primary tire size. Buyers who want a uniform look should compare front and rear availability carefully, since not every sidewall treatment offered in the rear size is also offered in the front size.
What brands offer tires for the 2019 Mercedes-Benz S65 AMG?
Tires for the 2019 Mercedes-Benz S65 AMG are available from BFGoodrich, Nitto, and Pro-Trac within the covered sizes. BFGoodrich appears in both the front and rear fitments, while Nitto and Pro-Trac are represented in the rear 285/35R20 size.
Brand comparison is most useful after the correct front or rear size has already been confirmed. Once axle position is settled, the next points to compare are tire series, sidewall treatment, and any stated rim-width specification, since those details affect both selection range and how the finished setup will look.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Mercedes-Benz S65 AMG?
A period-style choice for a 2019 Mercedes-Benz S65 AMG starts with keeping the proper staggered radial sizing in place: 255/40R20 front and 285/35R20 rear. From there, the decision becomes less about vintage construction and more about selecting a tire series and sidewall treatment that fits the car's character.
Because this is a modern AMG flagship, appearance choices tend to center on blackwall versus more expressive rear sidewall treatments such as raised white letter or redline. Buyers focused on an original-style presentation should compare current tires against vehicle-specific photos, delivery literature, or marque references before settling on a final look.
How does tire construction affect the appearance of a restored 2019 Mercedes-Benz S65 AMG?
Construction is straightforward on the 2019 Mercedes-Benz S65 AMG because the primary fitment is radial in both front and rear sizes. The larger appearance difference comes from tire series and sidewall style rather than from choosing between bias-ply and radial construction.
That keeps the visual decision focused on whether the car should retain a clean modern blackwall presentation or use a more stylized rear treatment such as raised white letter or redline. Owners building a highly accurate presentation should also consider wheel finish and overall stance so the tires suit the car as a complete package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mercedes-Benz S65 AMG?
Yes, modifications can affect tire fitment on a 2019 Mercedes-Benz S65 AMG even when the nominal tire size remains the same. Aftermarket wheels, altered wheel widths, suspension changes, or ride-height adjustments can all change how a 255/40R20 front or 285/35R20 rear tire sits within the wheelwell.
A car that has been lowered or fitted with different wheels deserves a closer check of clearance at full steering lock and through suspension travel. Tire selection should be based on the vehicle's actual current setup, not just its original size pattern, especially on a staggered performance-luxury platform with tight packaging.
What should I inspect before driving a 2019 Mercedes-Benz S65 AMG on new tires?
Before driving a 2019 Mercedes-Benz S65 AMG on new tires, inspect the wheel condition, confirm the front and rear sizes are mounted in the correct positions, and check inflation pressure carefully. It also makes sense to look over the valve stems, balance, and general mounting quality before the car is put back into regular road use.
A short initial drive should be used to confirm there is no rubbing, vibration, or unexpected steering behavior. Since this car uses a staggered 20-inch setup, even a simple front-to-rear mix-up can create immediate problems, so axle position and wheel compatibility deserve as much attention as the tire itself.
How often should tires on a 2019 Mercedes-Benz S65 AMG be inspected?
Tires on a 2019 Mercedes-Benz S65 AMG should be inspected regularly rather than only at replacement time. Frequent checks for pressure loss, uneven wear, cuts, punctures, sidewall damage, and vibration are especially worthwhile on a heavy, powerful grand-touring car running low-profile 20-inch radial tires.
Inspection matters even more if the car spends long periods parked, because low-use vehicles can still develop age-related issues or flat spotting. A quick look before longer drives and periodic checks of tread condition and wheel alignment can help catch problems early and keep the staggered setup working as intended.
