The 2007 Mercedes-Benz S63 AMG brought full-size luxury and AMG V8 performance together in one sharply modern sedan, making tire fitment a central part of how the car looks and responds on the road. This is a staggered setup rather than a single square size. The front uses 255/35R20 radial tires, while the rear uses 275/35R20 radials on 20-inch rims. That opens up meaningful choice in blackwall performance-oriented tires as well as RWL and redline sidewall treatments in select offerings. For an S63 AMG, the key is matching the correct front and rear sizes first, then choosing the tire series and appearance that best suits the car’s road use and presentation.
Which Tire Size Is Right for The 2007 Mercedes-Benz S63 AMG
The 2007 Mercedes-Benz S63 AMG uses two primary tire sizes, and they are position-specific rather than interchangeable. Both are radial tires for 20-inch rims, with 255/35R20 used on the front and 275/35R20 used on the rear. The first step is confirming that the car still has the proper staggered wheel setup, because tire selection starts with matching the correct size to the correct axle.
255/35R20 is a metric radial size in which 255 indicates nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2007 Mercedes-Benz S63 AMG, this is the front tire size in the staggered setup. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments depending on the tire series. This size matters because it preserves the intended front fitment profile, so it should be matched to the front wheels rather than treated as part of a square setup.
275/35R20 is also a metric radial size, with 275 indicating nominal section width in millimeters, 35 representing the aspect ratio, R for radial construction, and 20 for the wheel diameter in inches. On the 2007 Mercedes-Benz S63 AMG, this size is used at the rear as part of the factory-style staggered arrangement. BFGoodrich, Nitto, and Pro-Trac options are available here as well, with blackwall, raised white letter, and redline styles appearing across different tire series. This is the size to evaluate when confirming rear-wheel width, rear clearance, and the overall stance of the car.
Sub-model fitment on the 2007 Mercedes-Benz S63 AMG is straightforward in one sense and critical in another. The covered front and rear positions each use their own dedicated tire size, so identifying whether you are replacing a front or rear tire matters more than choosing between trim variations.

2007 Mercedes-Benz S63 AMG Base Front
The Base Front position uses the smaller of the two staggered radial sizes on a 20-inch rim. Tire selection here centers on maintaining the correct front fitment while choosing among available performance-oriented series and sidewall treatments.
The Base Rear position uses the wider staggered radial size on a 20-inch rim. That makes rear tire choice especially important when confirming wheel width, preserving the intended front-to-rear relationship, and selecting the sidewall style that suits the car’s 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 2007 Mercedes-Benz S63 AMG?
The 2007 Mercedes-Benz S63 AMG uses a staggered tire setup with 255/35R20 on the front and 275/35R20 on the rear. Both are radial tire sizes for 20-inch wheels, so this is not a single-size arrangement where the same tire belongs at all four corners.
That means the first step is identifying whether the tire being replaced is on the front axle or the rear axle. It is also worth confirming that the car still has the proper staggered wheel package, because aftermarket wheel changes can blur the original front-to-rear sizing relationship and affect what tire size should be used.
What size rim does a 2007 Mercedes-Benz S63 AMG use?
The tire sizes used on the 2007 Mercedes-Benz S63 AMG are built for 20-inch rims. Both the 255/35R20 front tire and the 275/35R20 rear tire share that same rim diameter, even though the rear tire is wider than the front.
Rim diameter is only one part of the fitment picture, so wheel width still matters when comparing actual tire choices. On a staggered car like the S63 AMG, checking both diameter and width helps keep the front and rear tires matched to the correct wheels and avoids ordering a tire that belongs on the opposite axle.
Why does the 2007 Mercedes-Benz S63 AMG have more than one tire size?
The 2007 Mercedes-Benz S63 AMG has more than one tire size because it uses a staggered setup. The front position takes 255/35R20, while the rear position takes 275/35R20, so the car uses a narrower front tire and a wider rear tire on the same 20-inch wheel diameter.
For the owner, that means tire replacement should be handled by axle position rather than by assuming all four tires match. Before choosing a tire, verify the wheel currently on the car, especially if it has been modified, rotated in a nonstandard pattern, or fitted with aftermarket wheels that may not follow the original staggered layout.
Choosing the Right Tire
What should I consider when choosing 255/35R20 and 275/35R20 tires for a 2007 Mercedes-Benz S63 AMG?
Start with the correct axle-specific size, since the 2007 Mercedes-Benz S63 AMG uses 255/35R20 in front and 275/35R20 in the rear. After that, compare tire construction, sidewall style, tire series, and wheel-width compatibility so the tires suit both the car’s layout and the look you want.
It also helps to think about how the car is used. A blackwall performance-style tire gives one appearance, while RWL or redline options create a more customized presentation. Matching the front and rear tires carefully, while checking wheel width and overall condition, usually matters more here than chasing one specification in isolation.
What sidewall styles are available for 2007 Mercedes-Benz S63 AMG tires?
Tires for the 2007 Mercedes-Benz S63 AMG are available in blackwall, RWL, and redline sidewall styles across the correct 255/35R20 front and 275/35R20 rear sizes. Blackwall is the most common presentation, while RWL and redline appear in select Pro-Trac Street Pro III offerings.
Sidewall style does not change the basic need to keep the staggered sizing correct, but it can change the character of the car visually. Blackwall tends to keep a more understated modern look, while RWL and redline move the car toward a more custom presentation, so choosing the style should follow the appearance goal as much as the fitment requirement.
What brands offer tires for the 2007 Mercedes-Benz S63 AMG?
BFGoodrich, Nitto, and Pro-Trac all offer tires in the sizes used by the 2007 Mercedes-Benz S63 AMG. Across the 255/35R20 and 275/35R20 fitments, the available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
The useful comparison is not just brand name, but how each option lines up with your priorities for sidewall treatment, wheel-width compatibility, and overall presentation. Some choices stay firmly in blackwall performance styling, while others add RWL or redline appearance, so the better question is which combination best matches the front and rear setup on your car.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Mercedes-Benz S63 AMG?
A period-style choice for a 2007 Mercedes-Benz S63 AMG starts with preserving the proper staggered fitment: 255/35R20 in front and 275/35R20 in the rear. From there, a blackwall tire usually keeps the most restrained, luxury-performance look, while alternate sidewall treatments move the car toward a more personalized presentation.
Tire series and sidewall treatment should be chosen with the car’s intended personality in mind rather than by assuming one option is historically exact. If originality matters at a detailed level, compare your selection against marque-specific documentation and the actual wheel setup on the car so appearance and fitment stay aligned.
How does tire construction affect the appearance of a restored 2007 Mercedes-Benz S63 AMG?
On a 2007 Mercedes-Benz S63 AMG, tire construction is straightforward because the primary fitment is radial in both front and rear sizes. That means appearance differences are driven less by bias-ply versus radial questions and more by profile, sidewall treatment, and the visual balance created by the staggered 20-inch setup.
A blackwall radial tends to support the car’s original modern luxury-performance character, while RWL or redline choices create a more custom look. Keeping the correct 255/35R20 front and 275/35R20 rear sizing is important visually, because the wrong front-to-rear relationship can change the stance and make the car look off even before it affects road manners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz S63 AMG?
Yes, modifications can affect tire fitment on a 2007 Mercedes-Benz S63 AMG, especially because it uses a staggered 255/35R20 front and 275/35R20 rear setup. Changes to wheel width, wheel offset, ride height, suspension components, or fender clearance can all alter what works safely and cleanly on the car.
Even when the rim diameter remains 20 inches, a modified car may not behave like a standard one from a fitment standpoint. It is wise to confirm the actual wheel dimensions on the car and inspect steering and body clearance before choosing tires, particularly if the S63 AMG has aftermarket wheels or suspension changes.
What should I inspect before driving a 2007 Mercedes-Benz S63 AMG on new tires?
Before driving a 2007 Mercedes-Benz S63 AMG on new tires, inspect that the correct size is mounted at each end of the car, with 255/35R20 in front and 275/35R20 in the rear. It is also smart to check inflation, wheel condition, valve stems, and general clearance around the suspension and inner fender areas.
A quick walkaround after installation can catch rubbing, uneven seating, or an obvious front-to-rear mismatch before the car goes into regular use. On a high-performance luxury sedan, alignment condition also matters, since worn components or poor alignment can shorten tire life quickly and make the new tires feel less settled than they should.
How often should tires on a 2007 Mercedes-Benz S63 AMG be inspected?
Tires on a 2007 Mercedes-Benz S63 AMG should be inspected regularly, not just when tread appears low. Frequent checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage are especially worthwhile on low-profile 20-inch tires, since problems can develop without being obvious from a distance.
A collector-driven or intermittently used car deserves extra attention because age and storage conditions can matter as much as mileage. Looking over the tires before longer drives, after seasonal storage, and whenever the car feels different on the road helps catch issues early and confirms that the staggered front and rear fitment is still in proper condition.
