The 2013 Mercedes-Benz S63 AMG blends full-size S-Class luxury with the added urgency and visual presence expected from an AMG flagship sedan. It belongs to an era when big power, advanced chassis tuning, and large-diameter wheel packages worked together to give a premium performance car a distinctly aggressive stance. Tire fitment follows that theme with a staggered radial setup: 255/35R20 in front and 275/35R20 in the rear, both on 20-inch rims. That makes the decision less about finding a single universal size and more about matching front and rear positions, sidewall style, and tire series. Wheel confirmation, appearance goals, and intended road use all matter before making a final choice.
Which Tire Size Is Right for The 2013 Mercedes-Benz S63 AMG
The 2013 Mercedes-Benz S63 AMG uses two primary tire sizes, and they are position-specific rather than interchangeable. The front uses 255/35R20 and the rear uses 275/35R20, both in radial construction on 20-inch rims. The first step is confirming whether the tire is for the front or rear axle, since the real decision is choosing the right tire series, sidewall treatment, and product specs within the correct staggered size.
A 255/35R20 size uses a 255-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2013 Mercedes-Benz S63 AMG, this is the front tire size in the staggered setup, so its role is tied to front-end fitment rather than all-around use. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments across several series. It is the size to select when replacing the front tires and when keeping the car's original front-to-rear fitment balance in view.
A 275/35R20 size carries a wider 275-millimeter nominal section width, the same 35-series profile, radial construction, and a 20-inch rim diameter. On the 2013 Mercedes-Benz S63 AMG, this size is used at the rear, making it a key part of the car's staggered performance-oriented tire arrangement. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline options depending on the series. It is the right size to evaluate when replacing the rear tires and preserving the intended front-to-rear difference in width.
Fitment on the 2013 Mercedes-Benz S63 AMG is straightforward in one sense and crucial in another: the covered configuration uses a staggered setup with different front and rear tire sizes. Checking position matters because the correct choice depends on whether the tire is going on the front axle or the rear axle.

2013 Mercedes-Benz S63 AMG Base Front
The Base Front position uses the narrower front fitment in the S63 AMG staggered setup, paired with radial construction on a 20-inch rim. Tire selection here centers on keeping the correct front size while comparing series, sidewall appearance, and wheel-width compatibility within that position.
The Base Rear position uses the wider rear tire size that completes the car's staggered radial fitment on a 20-inch rim. Choosing for the rear means matching the proper rear specification first, then comparing available tire series and sidewall styles without treating the front and rear sizes as interchangeable.
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 2013 Mercedes-Benz S63 AMG?
The 2013 Mercedes-Benz S63 AMG uses a staggered tire setup with 255/35R20 on the front and 275/35R20 on the rear. Both are radial tires designed for 20-inch rims, so the car does not use one universal size at all four corners.
That means the first step is identifying tire position before choosing a replacement. A front tire should be matched to the front size and a rear tire to the rear size, then compared by series, sidewall style, and wheel-width suitability. Any car that has had wheel or suspension changes should be measured carefully before ordering replacement tires.
What size rim does a 2013 Mercedes-Benz S63 AMG use?
The tire fitment for the 2013 Mercedes-Benz S63 AMG uses 20-inch rims at both the front and rear. The front 255/35R20 and rear 275/35R20 sizes share the same rim diameter even though they differ in section width.
Rim diameter is only part of the fitment picture, so the actual wheel width still matters when comparing tire choices. Some products in these sizes include stated rim-width ranges, which can help narrow the selection. On a modified car, wheel width and offset should be checked as closely as rim diameter before mounting new tires.
Why does the 2013 Mercedes-Benz S63 AMG have more than one tire size?
The 2013 Mercedes-Benz S63 AMG has more than one tire size because it uses a staggered setup, with one size assigned to the front axle and a wider size assigned to the rear. In this application, 255/35R20 is used in front and 275/35R20 is used in the rear.
For replacement planning, that means the car should be treated as a front-and-rear fitment rather than a single-size sedan. Tire shopping should start with axle position, then move to details such as tire series, sidewall presentation, and wheel compatibility. Any previous wheel swap or alignment-related modification makes it especially important to verify actual mounted dimensions at each end of the car.
Choosing the Right Tire
What should I consider when choosing a 255/35R20 and 275/35R20 tire for a 2013 Mercedes-Benz S63 AMG?
Start with the basics: front and rear position, correct size, radial construction, and 20-inch rim diameter. After that, compare the available tire series, sidewall treatments, and wheel-width suitability for each size, since the S63 AMG uses different front and rear specifications rather than one uniform fitment.
It also helps to think about how the car is used. A buyer focused on a clean modern look may prefer blackwall options, while someone after a more distinctive appearance may look at raised white letter or redline versions where offered. Load figures and product weight can also matter when comparing otherwise similar choices.
What sidewall styles are available for 2013 Mercedes-Benz S63 AMG tires?
The available sidewall styles for the 2013 Mercedes-Benz S63 AMG include blackwall, RWL, and redline, depending on the tire size and series. Those choices appear in both the 255/35R20 front size and the 275/35R20 rear size, giving the car a range of visual directions without changing the basic staggered fitment.
Sidewall style is mainly an appearance decision, but it still needs to be made within the correct front or rear size. A blackwall usually keeps the presentation understated, while raised white letter and redline versions create a more noticeable visual statement. Matching front and rear sidewall treatment is often just as important as matching the tire series.
What brands offer tires for the 2013 Mercedes-Benz S63 AMG?
BFGoodrich, Nitto, and Pro-Trac all offer tires in the sizes used on the 2013 Mercedes-Benz S63 AMG. Depending on front or rear fitment, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice should be treated as one part of the comparison rather than the whole decision. It still makes sense to confirm the exact axle position, the tire series, the sidewall style, and any stated rim-width or load information before selecting a tire. That approach keeps the choice tied to fitment and intended use, not just the name on the sidewall.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Mercedes-Benz S63 AMG?
A period-style choice for a 2013 Mercedes-Benz S63 AMG starts with preserving the correct staggered radial sizing: 255/35R20 in front and 275/35R20 in the rear. From there, the visual character comes from the tire series and sidewall treatment rather than from changing to an older construction type.
Because this is a modern AMG sedan, appearance decisions often revolve around whether the car should look understated or more expressive. Blackwall tires keep the presentation closest to a contemporary luxury-performance look, while redline or raised white letter options add a stronger custom flavor. The cleanest result usually comes from keeping the sidewall treatment consistent front to rear.
How does tire construction affect the appearance of a restored 2013 Mercedes-Benz S63 AMG?
On the 2013 Mercedes-Benz S63 AMG, the primary fitment is already radial, so construction choice is less about bias-ply versus radial appearance and more about preserving the car's intended modern performance-sedan stance. The visible difference usually comes from tread character, sidewall styling, and how the tire fills the wheel opening.
That makes size discipline especially important during a restoration-minded tire change. Keeping the correct front and rear sizes helps maintain the staggered look that suits the car, while sidewall choices such as blackwall, redline, or raised white letter can shift the visual tone. Any wheel change should be checked carefully so appearance goals do not create clearance issues.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Mercedes-Benz S63 AMG?
Yes. Modifications can affect tire fitment on a 2013 Mercedes-Benz S63 AMG even when the replacement tires match the original front and rear sizes. Wheel width, offset, lowering changes, alignment settings, and body or suspension alterations can all change how a 255/35R20 front or 275/35R20 rear tire sits in the car.
That is why a modified S63 AMG should be measured rather than assumed. Steering clearance up front, inner suspension clearance, and outer fender room all deserve attention before mounting new tires. Even a small change in wheel specification can alter real-world fitment, especially on a car that already uses a staggered low-profile setup.
What should I inspect before driving a 2013 Mercedes-Benz S63 AMG on new tires?
Before driving a 2013 Mercedes-Benz S63 AMG on new tires, inspect wheel condition, valve stems, mounting direction where applicable, and inflation pressure. It also helps to confirm that the front tires are the correct 255/35R20 size and the rear tires are the correct 275/35R20 size after installation.
A short, careful road test should follow the installation to check for rubbing, vibration, or unexpected steering feel. Tire-to-fender and tire-to-suspension clearance are worth rechecking if the car has aftermarket wheels or suspension changes. Lug torque and air pressure should be verified again after initial driving, especially on a heavy, high-performance luxury sedan.
How often should tires on a 2013 Mercedes-Benz S63 AMG be inspected?
Tires on a 2013 Mercedes-Benz S63 AMG should be inspected regularly, not just when tread appears worn. Low-profile performance tires can show damage from impacts, uneven wear, or air loss before the problem is obvious at a glance, so routine checks are especially worthwhile on a staggered 20-inch setup.
Monthly pressure checks and visual inspections are a sensible baseline, with closer inspection before longer drives or after hitting potholes or road debris. Look for cuts, bulges, irregular shoulder wear, and cracking around the sidewall or tread blocks. Because front and rear sizes differ, each axle should be evaluated on its own rather than assuming the same wear pattern everywhere.
