The 2014 Mercedes-Benz CLS63 AMG blends the four-door coupe shape of the CLS with AMG performance, making tire fitment especially important to both stance and road manners. On this model, the tire decision starts with a staggered 19-inch setup rather than a single all-around size. The front uses 255/35R19 and the rear uses 285/30R19, both in radial construction. Available choices in the front size center on BFGoodrich blackwall performance-oriented series, while the rear size must still be matched correctly to the vehicle's staggered layout. Before choosing a replacement, confirm front-versus-rear position, actual wheel dimensions, and whether the car still retains its original-style wheel and suspension setup.
Which Tire Size Is Right for The 2014 Mercedes-Benz CLS63 AMG
The 2014 Mercedes-Benz CLS63 AMG uses two primary tire sizes, both on 19-inch rims, because the car carries a staggered setup with a narrower front tire and a wider rear tire. The first step is identifying wheel position rather than choosing between alternate fitments, since the front and rear sizes serve different roles and should be matched to the correct end of the car.
255/35R19 is a modern metric radial size in which 255 represents section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2014 Mercedes-Benz CLS63 AMG, this size is used at the front, where precise wheel-position matching matters in a staggered setup. Available choices in this size come from BFGoodrich in blackwall form across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This is the size to evaluate when replacing worn front tires or comparing front-wheel compatibility against the car's current wheel width.
285/30R19 is a modern metric radial size with a 285-millimeter section width, a 30-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2014 Mercedes-Benz CLS63 AMG, this size is used at the rear as part of the car's staggered front-and-rear tire arrangement. Its wider footprint means it should be treated as a rear-position fitment rather than a general replacement size for the whole vehicle. This is the size to confirm when checking rear wheel dimensions, maintaining the intended staggered appearance, or replacing tires on a car that may have seen wheel or suspension changes.
Fitment on the 2014 Mercedes-Benz CLS63 AMG is straightforward once the tire position is identified, because the covered sub-models reflect the front and rear sides of the same staggered setup. Checking the exact front or rear application matters before selecting a replacement, even though both use 19-inch radial tires.

Tire Size & Fitment
What tire size fits a 2014 Mercedes-Benz CLS63 AMG?
The 2014 Mercedes-Benz CLS63 AMG uses a staggered radial setup with 255/35R19 at the front and 285/30R19 at the rear. Both sizes mount on 19-inch rims, but they are not the same tire size used at all four corners.
That means the first step is confirming whether the tire being replaced is on the front or rear axle. A staggered car can also have wheel changes over time, so it is smart to verify the actual wheel width and check current clearance before selecting replacement tires, especially if the vehicle has aftermarket wheels or suspension modifications.
What size rim does a 2014 Mercedes-Benz CLS63 AMG use?
The tire sizes used on the 2014 Mercedes-Benz CLS63 AMG are built for 19-inch rims. Both the 255/35R19 front tire and the 285/30R19 rear tire share that same rim diameter even though the tire widths and profiles differ.
Rim diameter is only one part of fitment, so it should not be the only number checked before replacement. Wheel width still matters, particularly on a performance car with staggered sizing, and a 19-inch wheel that is too narrow or too wide for the intended tire can affect how the tire seats and how the vehicle responds on the road.
Do all 2014 Mercedes-Benz CLS63 AMG sub-models use the same tire size?
The covered 2014 Mercedes-Benz CLS63 AMG sub-model entries do not use the same tire size because they separate the front and rear positions of the 4Matic setup. The front uses 255/35R19, while the rear uses 285/30R19.
That distinction matters because the staggered arrangement is part of how the car is set up. Front and rear tires should be ordered by position, and anyone replacing only one pair should confirm whether the existing tires match the wheel location correctly before moving ahead with a new set or a partial replacement.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2014 Mercedes-Benz CLS63 AMG?
Start with the correct wheel position, since 255/35R19 is the front size on the 2014 Mercedes-Benz CLS63 AMG. Then compare construction, rim-width compatibility, tire weight, and any load information that appears with the specific product, because those details help separate one radial option from another.
Appearance is straightforward in this case because the available front-size products are blackwall tires, so the real choice comes from series and specification differences. BFGoodrich options in this size include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, giving the buyer several front-tire choices without changing the actual fitment size.
What sidewall styles are available for 2014 Mercedes-Benz CLS63 AMG tires?
The available products in the 255/35R19 front size for the 2014 Mercedes-Benz CLS63 AMG use a blackwall sidewall style. That keeps the visual presentation clean and modern, which suits the character of a late-model AMG performance sedan with a staggered wheel-and-tire setup.
Sidewall style still matters because it affects the overall look of the car even when the tire size stays the same. In this fitment, sidewall selection is less about choosing between multiple cosmetic treatments and more about pairing the correct blackwall tire with the proper front position, wheel width, and intended use of the vehicle.
What tire series are available for the 2014 Mercedes-Benz CLS63 AMG?
For the 255/35R19 front size, the 2014 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. Each remains a radial blackwall tire in the correct front size, but the series names indicate different product lines within the same general performance-oriented family.
Choosing between tire series comes down to matching the right size with the right wheel while comparing the specific product details that matter to you. Looking at rim-width range, weight, and any stated load figures can help narrow the choice without losing sight of the larger fitment priority, which is keeping the CLS63 AMG's staggered front-and-rear setup intact.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Mercedes-Benz CLS63 AMG?
A period-style approach for a 2014 Mercedes-Benz CLS63 AMG starts with preserving the staggered radial sizing and the 19-inch wheel presentation rather than searching for a vintage-style tire. Keeping 255/35R19 at the front and 285/30R19 at the rear maintains the car's intended modern high-performance look.
Appearance on a vehicle from this era is shaped more by correct proportions and wheel-to-tire relationship than by whitewalls or other classic sidewall treatments. A buyer focused on visual authenticity should confirm the current wheel setup, avoid mismatched front and rear sizing, and compare blackwall options that suit the car's original-era character without overstepping into unsupported originality claims.
Does correct tire fitment matter for a 2014 Mercedes-Benz CLS63 AMG restoration?
Correct tire fitment matters on a 2014 Mercedes-Benz CLS63 AMG because the vehicle's appearance and stance depend on the proper staggered sizing. Using the right front and rear tire dimensions helps preserve the visual balance that belongs with this generation of AMG four-door coupe design.
It also matters mechanically, since an incorrect size can change how the tire sits on the wheel and how it clears nearby components. Anyone pursuing a restoration-minded result should verify wheel diameter, wheel width, and current front-versus-rear placement first, then compare tire options that respect the original fitment pattern rather than treating all four corners the same.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Mercedes-Benz CLS63 AMG?
Yes, modifications can affect tire fitment on a 2014 Mercedes-Benz CLS63 AMG even when the tire size itself sounds correct. Aftermarket wheels, altered wheel offsets, suspension lowering, alignment changes, or body modifications can all change how a 255/35R19 front or 285/30R19 rear tire sits in the wheel opening.
That is especially important on a staggered setup where front and rear tires already differ in width and profile. Checking actual wheel dimensions and inspecting for steering, fender, and suspension clearance before replacement can prevent buying the right nominal size for a car whose current hardware no longer matches its original-style configuration.
What should I inspect before driving a 2014 Mercedes-Benz CLS63 AMG on new tires?
Before driving a 2014 Mercedes-Benz CLS63 AMG on new tires, inspect tire pressure, confirm front and rear sizes are mounted in the correct positions, and look over the wheels for damage or mismatch. It is also wise to check valve stems, tread seating, and any visible clearance concerns around the suspension and fender areas.
A short road test should follow only after those basics are covered. During that first drive, pay attention to vibration, pulling, unusual rubbing, or signs that the car has a wheel or alignment issue unrelated to the tire itself, since a staggered high-performance setup can reveal small fitment problems quickly.
How often should tires on a 2014 Mercedes-Benz CLS63 AMG be inspected?
Tires on a 2014 Mercedes-Benz CLS63 AMG should be inspected regularly rather than only when tread looks worn. Routine checks for pressure loss, sidewall damage, punctures, uneven wear, and aging are important because low-profile performance tires can show fitment or maintenance issues before they become obvious from a casual glance.
Regular inspection matters even more if the car is driven seasonally or stored for long periods. Looking over the front and rear tires separately makes sense on this model because they are different sizes, and any uneven wear pattern can point to alignment, wheel, or suspension concerns that deserve attention before the next longer drive.
