The 2022 Mercedes-Benz S500 is a modern flagship sedan built around refinement, technology, and high-speed composure, so tire selection matters as much to the driving experience as it does to appearance and fitment. On this model, the first step is identifying the exact wheel and axle setup, because the S500 uses several primary radial tire sizes across 19-, 20-, and 21-inch rims, including staggered front and rear applications. That makes this page less about guessing a single size and more about matching the correct metric radial fitment to the car’s actual configuration. It also helps to compare available sidewall styles, tire series, and wheel-width compatibility before replacing anything.
Which Tire Size Is Right for The 2022 Mercedes-Benz S500
The 2022 Mercedes-Benz S500 uses five primary tire sizes, and the correct one depends on the exact wheel setup and whether the car is using a square or staggered arrangement. Because these fitments span 19-, 20-, and 21-inch rims and include separate front and rear sizes on some configurations, confirming the sub-model and wheel diameter should come before choosing a replacement tire.
255/40R20 is a metric radial size in which 255 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2022 Mercedes-Benz S500, this size is part of the primary fitment range and suits vehicles using a 20-inch wheel setup. Available choices in this size include a BFGoodrich g-Force Phenom T/A with a Blackwall sidewall and an 8.5- to 10-inch rim-width range. This size is worth evaluating when the car is equipped with 20-inch wheels and originality of wheel diameter matters more than changing overall fitment strategy.
255/45R19 is a metric radial size where 255 denotes nominal section width in millimeters, 45 is the aspect ratio, R means radial construction, and 19 identifies the wheel diameter. For the 2022 Mercedes-Benz S500, this size belongs to the 19-inch fitment path rather than the larger 20- or 21-inch wheel combinations. Its overall dimensions stay very close to the other front-size fitments used on this model, but the wheel diameter is different, so it should be matched to the actual rim on the car. This is the size to focus on when the S500 retains its 19-inch setup and the goal is to preserve that wheel configuration.
255/35R21 follows the modern metric radial format: 255 millimeters of nominal section width, a 35-series aspect ratio, radial construction, and a 21-inch rim diameter. On the 2022 Mercedes-Benz S500, this size serves as a front fitment in a 21-inch staggered arrangement, so it should be considered alongside the matching rear tire size rather than by itself. Its lower-profile format gives it a distinct role within the S500 fitment range compared with the 19- and 20-inch alternatives. Choosing this size starts with confirming that the car is running the 21-inch front wheel setup and not a square package.
285/30R21 is a metric radial size in which 285 is the nominal section width in millimeters, 30 is the aspect ratio, R marks radial construction, and 21 is the rim diameter. For the 2022 Mercedes-Benz S500, this is a rear tire size used with the 21-inch staggered setup, making it part of a front-and-rear pairing rather than a stand-alone fitment choice. Compared with the 255-series front sizes, it brings a wider rear footprint and should be matched carefully to the wheel and axle position. This size matters most when confirming a staggered 21-inch arrangement on the rear of the vehicle.
285/35R20 is a modern metric radial size: 285 indicates nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 20 identifies the wheel diameter. On the 2022 Mercedes-Benz S500, this size is used on the rear in a 20-inch staggered setup, so it should be selected with the rear axle application in mind. Product choice is broader here, with BFGoodrich, Nitto, and Pro-Trac options across g-Force Comp 2 AS, NT555 G2, and Street Pro III lines, plus Blackwall, RWL, and Redline sidewall treatments. This size is the one to study closely when the car runs 20-inch staggered wheels and appearance preferences are part of the decision.
Sub-model fitment on the 2022 Mercedes-Benz S500 is not one-size-fits-all, because wheel diameter and front-versus-rear application both affect the correct tire size. Checking the exact sub-model matters here, especially where staggered 20-inch or 21-inch setups separate the front and rear fitments.

Tire Size & Fitment
What tire size fits a 2022 Mercedes-Benz S500?
The 2022 Mercedes-Benz S500 uses several primary tire sizes: 255/45R19, 255/40R20, 255/35R21, 285/35R20, and 285/30R21. These are all radial fitments, and the correct size depends on the exact wheel package and whether the car is using a square setup or a staggered front-and-rear arrangement.
That means the first job is not picking a brand, but confirming the wheel diameter and axle position on the car. A front 255-size and a rear 285-size may both be correct on the same S500, but only within the proper staggered setup, so the existing wheels and current tire markings should be checked before replacement.
What size rim does a 2022 Mercedes-Benz S500 use?
The 2022 Mercedes-Benz S500 uses 19-inch, 20-inch, and 21-inch rim diameters depending on configuration. A 255/45R19 fits a 19-inch rim, 255/40R20 and 285/35R20 fit 20-inch rims, and the 255/35R21 and 285/30R21 sizes fit 21-inch rims.
Rim diameter is the most important fitment checkpoint on this model because several tire sizes have similar overall dimensions while still requiring different wheels. The tire sidewall and the wheel itself should both be verified before ordering, especially if the S500 has been fitted with optional wheels or changed from its original package.
Why does the 2022 Mercedes-Benz S500 have more than one tire size?
The 2022 Mercedes-Benz S500 has more than one tire size because it was fitted with different wheel diameters and, in some configurations, staggered front and rear tires. That is why 255-series front sizes appear alongside wider 285-series rear sizes, and why both 19-, 20-, and 21-inch rim diameters show up within the same model line.
This matters because the right replacement is tied to the car’s actual setup, not simply the model name on the trunk. Looking at the current front and rear tire sizes, checking the wheel diameter, and confirming whether the car has matching or staggered tires will prevent ordering a size that belongs to another S500 configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Mercedes-Benz S500?
Start with the exact tire size already assigned to the car’s wheel setup, since the 2022 Mercedes-Benz S500 uses several radial sizes across 19-, 20-, and 21-inch rims. After size, the next priorities are axle position, wheel-width compatibility where stated, sidewall appearance, tire series, and any load or speed markings shown on the replacement tire.
A square 19- or 20-inch arrangement calls for a different decision than a staggered setup with separate front and rear sizes. Buyers should also think about how the car is used, whether the current wheels are original to the vehicle, and whether appearance details such as Blackwall, RWL, or Redline matter as much as the technical fitment.
What sidewall styles are available for 2022 Mercedes-Benz S500 tires?
Available sidewall styles for the 2022 Mercedes-Benz S500 include Blackwall, RWL, and Redline, depending on the tire size and series being considered. Blackwall appears in both 255/40R20 and 285/35R20 offerings, while RWL and Redline appear among the 285/35R20 Pro-Trac Street Pro III choices.
Sidewall style does not change the required tire size, but it can change the visual character of the car significantly. A Blackwall keeps the presentation understated, while RWL or Redline introduces a more customized look, so buyers should confirm the correct fitment first and then choose the sidewall treatment that best suits the car’s appearance.
What brands offer tires for the 2022 Mercedes-Benz S500?
Tire options for the 2022 Mercedes-Benz S500 include BFGoodrich, Nitto, and Pro-Trac in the sizes currently offered for this model’s fitment range. BFGoodrich appears in both 255/40R20 and 285/35R20 applications, while Nitto and Pro-Trac are available in 285/35R20.
Brand choice should come after confirming the exact size and wheel diameter on the car. Once that is settled, it becomes easier to compare the available tire series, sidewall treatments, and stated wheel-width compatibility so the replacement matches both the S500’s configuration and the owner’s priorities for appearance and use.
Restoration & Appearance
How does tire construction affect the appearance of a 2022 Mercedes-Benz S500?
On the 2022 Mercedes-Benz S500, the primary fitments are radial tires, so construction changes are less about vintage authenticity and more about how modern tire design complements the car’s look. In practical terms, the most visible appearance differences come from profile, wheel diameter, and sidewall treatment rather than from choosing between bias-ply and radial construction.
That makes details such as Blackwall, RWL, and Redline more important to the visual result than construction type on this model. A lower-profile 21-inch setup presents differently from a 19-inch arrangement, so the final appearance depends on keeping the tire size matched to the wheel package already on the car.
Does correct tire fitment matter for the appearance of a 2022 Mercedes-Benz S500?
Correct tire fitment has a major effect on how a 2022 Mercedes-Benz S500 sits and presents. The model uses several carefully proportioned metric radial sizes, and moving away from the intended wheel diameter or front-to-rear relationship can change the visual balance of the car even before any driving differences are considered.
That is especially true on staggered setups, where the wider rear tire is part of the overall look. Keeping the proper 19-, 20-, or 21-inch fitment path and selecting a sidewall style that suits the car’s character will usually do more for appearance than chasing a tire that simply seems close in size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Mercedes-Benz S500?
Yes, modifications can affect tire fitment on a 2022 Mercedes-Benz S500. Aftermarket wheels, suspension changes, altered ride height, spacers, or body modifications can all change the clearance relationship around 255- and 285-series tires, even when the replacement size matches one of the model’s original fitment patterns.
A car with changed wheels may need closer attention to rim width, offset, and steering or fender clearance than a stock example. It is smart to inspect the current setup carefully and compare the tire size on each axle before replacing anything, especially when the S500 is running a staggered front-and-rear arrangement.
What should I inspect before driving a 2022 Mercedes-Benz S500 on new tires?
Before driving a 2022 Mercedes-Benz S500 on new tires, inspect the wheel diameter, confirm the size on each axle, and make sure the tires are mounted in the correct front or rear position where staggered fitment applies. It is also worth checking for visible sidewall damage, uneven tread wear on the old tires, and any wheel damage that could affect mounting.
Air pressure should be set correctly for the new installation, and the vehicle should be checked for rubbing at full steering lock or over suspension movement if anything about the wheel package has changed. A quick look at alignment condition can also help prevent fresh tires from developing uneven wear early.
How often should tires on a 2022 Mercedes-Benz S500 be inspected?
Tires on a 2022 Mercedes-Benz S500 should be inspected regularly, with closer attention any time the car has been parked for extended periods, hits road debris, or shows a change in ride quality. Basic checks include air pressure, tread condition, cuts, bulges, irregular wear, and any sign that the front and rear tires are not wearing evenly.
Routine inspection matters even more on staggered setups because front and rear sizes are different and cannot simply be treated as interchangeable. A consistent walkaround before longer drives helps catch damage or pressure loss early, and it also gives owners a chance to confirm that each tire still matches the wheel position where it belongs.
