The 2013 Mercedes-Benz CLS63 AMG sits at the intersection of luxury coupe styling and serious AMG performance, blending high-output power with the long, low proportions that made the CLS a standout in the modern performance-sedan world. Tire fitment on this car is not a one-size decision, because it uses a staggered 19-inch setup with 255/35R19 in front and 285/30R19 in the rear, both in radial construction. That makes the real choice less about whether two sizes apply and more about matching each position correctly. For owners focused on road use, wheel compatibility, and preserving the car’s intended stance, confirming front-to-rear placement is the key first step.
Which Tire Size Is Right for The 2013 Mercedes-Benz CLS63 AMG
The 2013 Mercedes-Benz CLS63 AMG uses two primary tire sizes, and they serve different positions on the car rather than different trim levels. Both are radial tires for 19-inch rims, with 255/35R19 used at the front and 285/30R19 used at the rear. Before choosing a tire, the first step is confirming whether you are replacing a front or rear tire so the staggered setup stays properly matched.
255/35R19 is a modern metric radial size in which 255 refers to nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2013 Mercedes-Benz CLS63 AMG, this size is used at the front, where proper steering response and clearance depend on keeping the correct front fitment. Available choices in this size come from BFGoodrich, all in Blackwall form, with g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series options. This is the size to evaluate when replacing the front pair or correcting a mismatched setup.
285/30R19 is also a modern metric radial size, with 285 indicating nominal section width in millimeters, 30 describing the aspect ratio, R for radial construction, and 19 for the wheel diameter. On the 2013 Mercedes-Benz CLS63 AMG, this size belongs at the rear as part of the factory-style staggered arrangement. Its role is distinct from the front tire, so it should be treated as a rear-position fitment rather than an interchangeable alternative to 255/35R19. This is the size to verify when replacing rear tires or checking whether the car still has the proper front-to-rear balance.
Fitment on the 2013 Mercedes-Benz CLS63 AMG is straightforward once the tire position is identified, because the covered configuration uses a staggered setup rather than multiple trim-specific combinations. Checking front versus rear matters here, since each end of the car uses a different 19-inch radial size.

2013 Mercedes-Benz CLS63 AMG Base Front
The 2013 Mercedes-Benz CLS63 AMG Base Front uses its own dedicated front tire size in radial construction on a 19-inch rim. That means front tire replacement should focus on maintaining the correct steering-end fitment and comparing options within the proper size rather than mixing front and rear applications.
The 2013 Mercedes-Benz CLS63 AMG Base Rear uses a separate rear tire size, also in radial construction on a 19-inch rim. Rear tire selection should keep the staggered layout intact and should be checked carefully if the car has aftermarket wheels or any changes that could affect width or clearance.
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.
Best 2013 Mercedes-Benz CLS63 AMG Tires for Sale
Current 255/35R19 choices center on BFGoodrich radial performance tires in Blackwall styling, including the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. The main comparisons are tire series, load-related specifications, weight, and rim-width compatibility.
Owners of a 2013 Mercedes-Benz CLS63 AMG usually need clarity on the staggered front-and-rear tire sizes, 19-inch rim fitment, available radial choices, and what to inspect before putting a high-performance car back on the road.
Tire Size & Fitment
What tire size fits a 2013 Mercedes-Benz CLS63 AMG?
The 2013 Mercedes-Benz CLS63 AMG uses a staggered tire setup with 255/35R19 at the front and 285/30R19 at the rear. Both are radial sizes mounted on 19-inch wheels, so the car does not use the same tire size at all four corners.
That means tire selection starts with position, not just year and model. A front replacement should match the 255/35R19 fitment, while a rear replacement should match 285/30R19. If the car has changed wheels, confirm actual wheel width and clearance before assuming the original staggered sizing is still in place.
What size rim does a 2013 Mercedes-Benz CLS63 AMG use?
The primary tire fitments for the 2013 Mercedes-Benz CLS63 AMG both use a 19-inch rim diameter. The front 255/35R19 and rear 285/30R19 sizes are both built around that same wheel diameter, even though the section widths and profiles differ.
Rim diameter is only one part of the fitment picture on a staggered performance car. Wheel width also matters, especially if replacement wheels have been installed. Checking the actual wheel dimensions before mounting new tires helps avoid problems with sidewall shape, handling balance, and clearance at either end of the car.
Why does the 2013 Mercedes-Benz CLS63 AMG have more than one tire size?
The 2013 Mercedes-Benz CLS63 AMG uses more than one tire size because it has a staggered setup, with one size for the front axle and a wider one for the rear. In this configuration, 255/35R19 is used in front and 285/30R19 is used in back.
That arrangement means tire choice is tied to location on the car rather than trim variation. Keeping the correct front-to-rear sizing preserves the intended wheel-and-tire relationship. If the car has been modified with different wheels, lowered suspension, or nonstandard offsets, measure carefully before replacing tires by original size alone.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2013 Mercedes-Benz CLS63 AMG?
Choosing a 255/35R19 front tire for a 2013 Mercedes-Benz CLS63 AMG starts with confirming the car still uses the original front size on a 19-inch wheel. Available options in this size include BFGoodrich radial tires in Blackwall styling across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series.
After size confirmation, compare the details that affect how the tire suits the car and wheel. Rim-width compatibility, load-related specifications, tire weight, and the intended use of the vehicle all matter. A regularly driven car may call for a different choice than one used occasionally or kept close to a stock-style presentation.
What sidewall styles are available for 2013 Mercedes-Benz CLS63 AMG tires?
The currently available 255/35R19 tire choices for the 2013 Mercedes-Benz CLS63 AMG use Blackwall sidewalls. That keeps the appearance clean and modern, which suits the car’s AMG-era performance character without introducing whitewall, redline, or other vintage-style sidewall treatments.
Sidewall style is mostly an appearance decision, but it also helps narrow the product field quickly. On this application, Blackwall keeps the focus on selecting the right tire series and specifications rather than choosing among decorative sidewall variations. Front and rear fitment still need to be confirmed separately because the car uses different sizes at each end.
What tire series are available for the 2013 Mercedes-Benz CLS63 AMG?
For the 255/35R19 front size, the 2013 Mercedes-Benz CLS63 AMG has BFGoodrich options in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. All of them are radial Blackwall tires, but they are still distinct product lines within the same basic fitment category.
Series names help separate one product from another when the size itself is already settled. Comparing series is useful when looking at wheel-width compatibility, weight, and load-related details, or when trying to match how the car will be driven. The important first step is still making sure the tire being compared is for the correct axle position.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Mercedes-Benz CLS63 AMG?
Yes, modifications can affect tire fitment on a 2013 Mercedes-Benz CLS63 AMG even when the original sizes are known. Changes such as aftermarket wheels, altered offsets, suspension lowering, spacer use, or bodywork changes can alter the space available for a 255/35R19 front tire or a 285/30R19 rear tire.
A car with modifications should be measured rather than treated like a stock setup automatically. Wheel width, wheel position in the fender opening, and clearance at full steering lock all deserve attention before mounting replacement tires. That is especially important on a staggered performance application where front and rear sizing already differ by design.
What should I inspect before driving a 2013 Mercedes-Benz CLS63 AMG on new tires?
Before driving a 2013 Mercedes-Benz CLS63 AMG on new tires, inspect wheel condition, verify that front and rear sizes were mounted in the correct positions, and confirm inflation is set appropriately for the installed tires and vehicle use. A visual check for damage, bead seating, and any immediate interference is also worthwhile.
The first road test should be short and deliberate rather than a long highway run. Pay attention to steering feel, vibration, rubbing, and whether the car tracks evenly under normal driving. Any sign of contact with suspension parts or fender liners should be addressed immediately, especially on a low-profile 19-inch staggered setup.
How often should tires on a 2013 Mercedes-Benz CLS63 AMG be inspected?
Tires on a 2013 Mercedes-Benz CLS63 AMG should be inspected regularly, not just when tread appears worn. A quick visual check before driving and a more thorough inspection at routine service intervals helps catch uneven wear, sidewall damage, cuts, punctures, or air loss before they become larger problems.
Regular inspection matters even more on a performance car with low-profile front and rear tires. The staggered setup means each axle can wear differently, so front and rear condition should be reviewed separately. Cars that sit for longer periods also deserve checks for age-related cracking, flat spotting, and pressure loss before being driven again.
