The 2014 Mercedes-Benz CLS63 AMG S blends four-door grand touring style with the sharper edge of AMG performance, making tire choice especially important to how the car looks and responds on the road. On this model, fitment centers on a staggered 19-inch radial setup with 255/35R19 in front and 285/30R19 in the rear. That means the main decision is not whether one size fits all corners, but whether the correct front or rear size is being matched to the car's wheel position. For owners replacing worn tires, it is worth confirming wheel placement, maintaining the intended staggered stance, and checking any modifications before selecting a replacement.
Which Tire Size Is Right for The 2014 Mercedes-Benz CLS63 AMG S
The 2014 Mercedes-Benz CLS63 AMG S uses two primary tire sizes, and they are position-specific rather than interchangeable. Both are radial tires mounted on 19-inch rims, with 255/35R19 used at the front and 285/30R19 used at the rear. Before choosing a tire, confirm whether the wheel being fitted is on the front or rear axle, since the staggered setup is the key fitment detail on this car.
255/35R19 is a metric radial size in which 255 refers to nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2014 Mercedes-Benz CLS63 AMG S, this size is used on the front of the 4Matic setup and plays a central role in preserving the intended staggered fitment. Available choices in this size include BFGoodrich options in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, all with Blackwall styling. This is the size to evaluate when replacing front tires and confirming front-wheel width compatibility.
285/30R19 is a metric radial size where 285 identifies nominal section width in millimeters, 30 is the aspect ratio, R denotes radial construction, and 19 identifies the wheel diameter. On the 2014 Mercedes-Benz CLS63 AMG S, this size is used at the rear to complete the staggered tire arrangement. Its role is different from the front size, so it should be selected specifically for the rear axle rather than treated as part of a square setup. Owners replacing rear tires should confirm the actual rear wheel dimensions and check clearance carefully if the car has aftermarket wheels or suspension changes.
Fitment on the 2014 Mercedes-Benz CLS63 AMG S is straightforward once the wheel position is identified, because the covered sub-model entries separate front and rear tire sizes. Checking the exact front or rear application matters here, since this car uses a staggered setup rather than the same size at all four corners.

Tire Size & Fitment
What tire size fits a 2014 Mercedes-Benz CLS63 AMG S?
The 2014 Mercedes-Benz CLS63 AMG S uses a staggered tire setup with 255/35R19 on the front and 285/30R19 on the rear. Both are radial sizes mounted on 19-inch wheels, so this car does not use one universal tire size at all four corners.
The key step is matching the tire to the correct axle position before ordering or mounting anything. A front tire and rear tire on this model serve different fitment roles, so wheel location, wheel width, and any prior modifications should be checked before replacement.
What size rim does a 2014 Mercedes-Benz CLS63 AMG S use?
The 2014 Mercedes-Benz CLS63 AMG S uses 19-inch rims with both primary tire sizes. The front 255/35R19 and rear 285/30R19 each share the same rim diameter, even though the tire widths and aspect ratios differ as part of the staggered layout.
Rim diameter is only one part of fitment, so it is still important to confirm actual wheel width before choosing a replacement tire. That matters even more if the car has been fitted with aftermarket wheels, since a correct 19-inch diameter alone does not confirm full compatibility.
Why does the 2014 Mercedes-Benz CLS63 AMG S have more than one tire size?
The 2014 Mercedes-Benz CLS63 AMG S has more than one tire size because it uses a staggered fitment. The front position takes 255/35R19, while the rear position uses 285/30R19, giving the car different tire dimensions at each axle rather than a square four-corner setup.
That arrangement means replacement decisions start with wheel position, not just rim diameter. Owners should avoid assuming the front and rear sizes can be mixed freely, and should confirm the actual wheel setup on the car if anything has been changed from the standard staggered configuration.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2014 Mercedes-Benz CLS63 AMG S?
Start with the fact that 255/35R19 is the front tire size for the 2014 Mercedes-Benz CLS63 AMG S 4Matic. Available options in this size use radial construction and Blackwall styling, so the main differences come from tire series, load details, weight, and the wheel-width range each tire is built to support.
Selection should match how the car is actually used and the wheel it is mounted on. A careful comparison of rim-width compatibility, sidewall profile, and other published specifications will help narrow the choices without treating every 255/35R19 tire as identical in character or application.
What brands offer tires for the 2014 Mercedes-Benz CLS63 AMG S?
BFGoodrich offers available tire choices in the 255/35R19 fitment used on the front of the 2014 Mercedes-Benz CLS63 AMG S. Within that size, the brand appears across multiple g-Force series, giving buyers several ways to compare tires while staying within the correct front fitment.
The real comparison is not just brand name, but which series best matches the intended use and wheel specification. Looking at details such as rim-width range, load figures where shown, and overall product character is more useful than assuming every tire from the same brand serves the same purpose.
What tire series are available for the 2014 Mercedes-Benz CLS63 AMG S?
In the available 255/35R19 fitment for the 2014 Mercedes-Benz CLS63 AMG S, the tire series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. All are radial Blackwall tires, but they give the buyer different product families to compare within the same size.
That makes series selection an important part of choosing a replacement, especially when the goal is to match use and wheel setup rather than simply match the printed size. Comparing the series alongside rim-width specifications and other product details helps narrow the right front-tire option more effectively.
Restoration & Appearance
Does correct tire fitment matter for a 2014 Mercedes-Benz CLS63 AMG S restoration?
Correct tire fitment still matters on a 2014 Mercedes-Benz CLS63 AMG S even though it is a newer collector-era performance sedan rather than an older restoration car. The car uses a staggered 19-inch setup, so keeping the proper front 255/35R19 and rear 285/30R19 relationship is part of preserving its intended stance and overall presentation.
Appearance is only one part of that decision, because an incorrect front-to-rear match can also change how the wheel openings are visually filled. Owners pursuing an accurate presentation should confirm the car's current wheel setup and compare replacement tires carefully before moving away from the established staggered sizing.
How does tire construction affect the appearance of a restored 2014 Mercedes-Benz CLS63 AMG S?
Tire construction is less about bias-ply versus radial on a 2014 Mercedes-Benz CLS63 AMG S, since its primary fitments are radial. The visible appearance difference comes more from maintaining the correct low-profile front and rear sizing, along with choosing a sidewall treatment that suits the car's modern AMG character.
Blackwall presentation is available in the front fitment, which keeps the look clean and contemporary rather than overtly vintage. For owners focused on appearance, preserving the staggered proportions and confirming wheel width usually has a greater visual effect than chasing cosmetic changes that move away from the car's intended layout.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Mercedes-Benz CLS63 AMG S?
Yes, modifications can affect tire fitment on a 2014 Mercedes-Benz CLS63 AMG S, especially because the car already uses a staggered setup with different front and rear sizes. Changes such as aftermarket wheels, altered offsets, suspension lowering, or body modifications can influence clearance even when the tire size itself looks correct on paper.
A modified car should be checked at the wheel, not judged by size designation alone. Steering clearance, fender clearance, and actual wheel width all matter, particularly with low-profile 19-inch tires, so it is smart to confirm the complete setup before installing replacement tires.
What should I inspect before driving a 2014 Mercedes-Benz CLS63 AMG S on new tires?
Before driving a 2014 Mercedes-Benz CLS63 AMG S on new tires, inspect wheel condition, verify that the correct front and rear sizes were mounted, and confirm that air pressure is set appropriately for the tires in use. It is also worth checking for any visible damage, uneven seating, or interference at full steering lock.
A short initial check can prevent fitment surprises once the car is back on the road. Recheck for rubbing, unusual vibration, and signs of air loss after the first drive, and pay special attention if the car has non-standard wheels or suspension changes that could affect clearance.
What should I check before a longer drive in a 2014 Mercedes-Benz CLS63 AMG S?
Before a longer drive in a 2014 Mercedes-Benz CLS63 AMG S, confirm tire pressure, inspect tread and sidewalls for cuts or bulges, and make sure the staggered front and rear sizes are still matched to the proper wheel positions. On a low-use performance car, age and condition can matter just as much as remaining tread.
A longer trip puts more emphasis on consistency and heat buildup, so it helps to start with a careful visual inspection and a pressure check on all four tires. Any sign of cracking, repeated air loss, or contact with suspension or bodywork should be addressed before the car is driven at distance.
