The 2018 Mercedes-Benz E63 AMG S blends modern super-sedan performance with the long-running E-Class tradition of combining luxury, technology, and serious road speed in one package. In this generation, the AMG S model stands apart as a high-output 4Matic car with the kind of grip and balance that depend heavily on proper front-to-rear tire fitment. This car uses a staggered radial setup with 265/35R20 in front and 295/30R20 in the rear, both on 20-inch rims. Available choices include performance-oriented blackwall tires as well as Redline and raised white letter alternatives in the front size. The key decision is preserving the intended staggered layout while matching tire style to the car’s appearance and use.
Which Tire Size Is Right for The 2018 Mercedes-Benz E63 AMG S
The 2018 Mercedes-Benz E63 AMG S uses two primary tire sizes, and the difference is tied directly to position on the car rather than trim variation. Both sizes are radial tires for 20-inch rims, so the first step is confirming whether you are replacing the front or rear tires before comparing brands, sidewall styles, and product specifications.
265/35R20 is a metric radial size in which 265 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2018 Mercedes-Benz E63 AMG S, this is the front tire size in the staggered setup. Available choices in this size include blackwall, Redline, and raised white letter sidewalls, with options from Nitto, BFGoodrich, and Pro-Trac across series such as NT555 G2, g-Force Phenom T/A, and Street Pro III. Choosing this size means matching the car’s front fitment while selecting the appearance and specification details that suit your driving and presentation goals.
295/30R20 is a metric radial size where 295 indicates nominal section width in millimeters, 30 is the aspect ratio, R denotes radial construction, and 20 identifies the wheel diameter in inches. On the 2018 Mercedes-Benz E63 AMG S, this size is used at the rear as part of the car’s staggered front-to-rear tire arrangement. Its role is different from the front tire size, so it should be evaluated as a rear-position fitment rather than as an interchangeable match for both ends of the car. Confirming rear wheel position and maintaining the intended staggered layout are the practical priorities when selecting this size.
Sub-model fitment on this application is position-specific rather than trim-based. Checking whether the tire is for the front or rear of the 4Matic setup matters first, because the E63 AMG S uses a staggered arrangement with different sizes at each end.

2018 Mercedes-Benz E63 AMG S 4Matic Front
The 2018 Mercedes-Benz E63 AMG S 4Matic Front uses the smaller of the two 20-inch radial tire sizes in the staggered setup. That makes front tire selection more about choosing the right brand, sidewall treatment, and performance-focused series while keeping the intended front fitment intact.
The 2018 Mercedes-Benz E63 AMG S 4Matic Rear uses its own wider 20-inch radial tire size, separate from the front. Rear replacement should focus on preserving the staggered layout and confirming that the selected tire matches the wheel position, wheel size, and clearance needs at the back of 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.

Common questions for the 2018 Mercedes-Benz E63 AMG S usually center on its staggered tire sizing, 20-inch rim fitment, front-versus-rear replacement, available product styles, and the checks worth making before putting fresh tires into road use.
Tire Size & Fitment
What tire size fits a 2018 Mercedes-Benz E63 AMG S?
The 2018 Mercedes-Benz E63 AMG S uses a staggered tire setup with two different radial sizes: 265/35R20 in front and 295/30R20 in the rear. Both sizes mount on 20-inch rims, but they are assigned to specific positions on the car rather than used interchangeably.
That means the first step is identifying whether you are replacing the front tires, the rear tires, or the full set. A staggered layout affects balance, clearance, and overall appearance, so matching each size to the correct axle is more important than simply choosing any 20-inch tire that looks close.
What size rim does a 2018 Mercedes-Benz E63 AMG S use?
The tire sizes used on the 2018 Mercedes-Benz E63 AMG S are built around a 20-inch rim diameter. Both the 265/35R20 front tire and the 295/30R20 rear tire are intended for 20-inch wheels, even though the front and rear tire widths and profiles are different.
Rim diameter is only one part of fitment, so it helps to confirm wheel width and actual front or rear wheel position before ordering replacements. A 20-inch wheel is required for these sizes, but proper selection still depends on using the right tire at the right end of the car.
Do all 2018 Mercedes-Benz E63 AMG S sub-models use the same tire size?
The covered 2018 Mercedes-Benz E63 AMG S 4Matic fitment does not use the same tire size at all positions. The front uses 265/35R20, while the rear uses 295/30R20, so the car relies on a staggered arrangement rather than a single uniform size.
That distinction matters whenever only two tires are being replaced or when wheels have been changed from stock-style sizing. Verifying front versus rear placement prevents ordering the wrong width and profile, and it helps preserve the intended stance and tire relationship designed into this AMG setup.
Choosing the Right Tire
What should I consider when choosing a 265/35R20 tire for a 2018 Mercedes-Benz E63 AMG S?
Start with the fact that 265/35R20 is the front tire size for the 2018 Mercedes-Benz E63 AMG S. Within that size, available choices vary by brand, tire series, sidewall style, weight, and in some cases rim-width specification, so selection is about more than simply matching the printed size.
A buyer focused on a modern performance look may lean toward blackwall options, while someone after a more distinctive presentation may prefer Redline or raised white letter styling. It also helps to compare wheel compatibility details and use pattern, especially if the car is driven aggressively or wears non-original wheels.
What sidewall styles are available for 2018 Mercedes-Benz E63 AMG S tires?
In the available 265/35R20 front tire selection for the 2018 Mercedes-Benz E63 AMG S, sidewall styles include Blackwall, Redline, and RWL, which is raised white letter. Those options give the same front tire size noticeably different visual character without changing the basic front fitment format.
Sidewall choice is largely an appearance decision, but it should still be made within the correct size and application. A blackwall presentation suits a more understated modern look, while Redline and raised white letter styles create a more custom or enthusiast-oriented appearance on a sedan with strong visual presence.
What brands offer tires for the 2018 Mercedes-Benz E63 AMG S?
Available tires for the 2018 Mercedes-Benz E63 AMG S front size include Nitto, BFGoodrich, and Pro-Trac. Those brands cover several product directions within 265/35R20, including the Nitto NT555 G2, BFGoodrich g-Force Phenom T/A, and Pro-Trac Street Pro III lines.
Brand choice should be compared alongside the rest of the tire details rather than viewed by name alone. The useful differences here include sidewall treatment, tire series, weight, and wheel-compatibility information, all of which can matter when the goal is matching the car’s intended look and front-end fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Mercedes-Benz E63 AMG S?
A period-style approach for a 2018 Mercedes-Benz E63 AMG S still starts with the correct staggered sizing: 265/35R20 in front and 295/30R20 in the rear. Since this is a modern AMG sedan, the choice is less about vintage construction and more about keeping the proper size relationship while selecting a tire that complements the car’s visual character.
Blackwall tires preserve a cleaner contemporary performance look, while specialty sidewall treatments in the front size can create a more personalized presentation. The best path is to keep the correct front-to-rear fitment first, then choose sidewall style and series based on whether the car is being preserved, customized, or regularly driven.
How does tire construction affect the appearance of a restored 2018 Mercedes-Benz E63 AMG S?
On a 2018 Mercedes-Benz E63 AMG S, construction is straightforward because the primary fitment is radial. That means appearance differences come more from sidewall styling, tire profile, and the maintained staggered front-rear proportions than from choosing between bias-ply and radial construction.
Keeping the correct 265/35R20 front and 295/30R20 rear sizing helps preserve the car’s intended stance and visual balance. From there, blackwall, Redline, or raised white letter details can shift the look from understated to more expressive, but the strongest appearance decision is still getting the proper fitment relationship correct.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Mercedes-Benz E63 AMG S?
Yes. Any change to wheels, suspension height, alignment settings, or body clearance can affect tire fitment on a 2018 Mercedes-Benz E63 AMG S, especially because the car uses a staggered 20-inch setup with different front and rear sizes. Even small changes can alter how each tire sits in the wheel opening.
Aftermarket wheels should be checked for correct diameter, width, and position before replacing tires. Lowering, spacer use, or fender modifications can also change clearance at full steering lock or suspension movement, so confirming front and rear space separately is a smart step before mounting a new set.
What should I inspect before driving a 2018 Mercedes-Benz E63 AMG S on new tires?
Before driving on new tires, inspect basic fitment and condition points such as correct front and rear sizing, proper inflation, valve condition, bead seating, and visible clearance around suspension and bodywork. On a staggered 2018 Mercedes-Benz E63 AMG S, it is especially important to confirm that the front and rear tires were not mixed.
A short visual check after installation can prevent avoidable problems. Look for rubbing marks, uneven stance, or any sign of air loss, then recheck pressure after the first miles of use. Cars with aftermarket wheels or suspension changes deserve extra attention because clearance issues may not appear until the car is in motion.
How often should tires on a 2018 Mercedes-Benz E63 AMG S be inspected?
Tires on a 2018 Mercedes-Benz E63 AMG S should be inspected regularly, not just when tread looks worn. A quick check for pressure, cuts, punctures, sidewall damage, and uneven wear is worthwhile before longer drives, and a more careful inspection should be part of normal routine maintenance.
This matters even more on a high-performance staggered setup, where front and rear tires may wear differently and cannot simply be treated as interchangeable. Cars that sit for extended periods should also be checked for flat spotting, age-related cracking, and gradual air loss before being returned to regular road use.
