The 2020 Mercedes-Benz CLS53 AMG blends the coupe-like roofline of the CLS with AMG six-cylinder performance and 4Matic all-wheel-drive traction, making tire fitment more than a cosmetic decision. On this model, fitment centers on a staggered radial setup, with different front and rear sizes and either 19-inch or 20-inch wheel diameters depending on the wheel package. That means the key question is not simply width, but confirming both axle position and rim diameter before choosing tires. Available options focus on modern blackwall performance radials from BFGoodrich and Nitto, with several series choices up front and in the 19-inch rear size. For daily road use, replacement planning starts with matching the exact front or rear size to the wheels currently on the car.
Which Tire Size Is Right for The 2020 Mercedes-Benz CLS53 AMG
The 2020 Mercedes-Benz CLS53 AMG uses four primary tire sizes because it runs a staggered setup and was fitted with either 19-inch or 20-inch wheels. Front tires use a 245-section size and rear tires use a wider 275-section size, so the first step is confirming both axle position and wheel diameter before selecting a replacement radial.
245/35R20 is a metric radial size with a 245-millimeter section width, a 35-series aspect ratio, and a 20-inch rim diameter. On the 2020 Mercedes-Benz CLS53 AMG, this size is used on the front axle when the car is equipped with the 20-inch wheel setup, so it should be matched to the correct wheel package rather than treated as a universal fitment. Available choices include BFGoodrich and Nitto blackwall radials across g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. This size is the one to evaluate when replacing front 20-inch tires while keeping the staggered relationship intact.
245/40R19 is a metric radial size that uses a 245-millimeter section width, a 40-series profile, and a 19-inch rim diameter. On this CLS53 AMG, it serves as the front tire size for the 19-inch wheel configuration, making wheel diameter confirmation essential before ordering a replacement. BFGoodrich offers this size in several blackwall performance radial series, including g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A. It is the correct front-size path to compare when the car wears 19-inch wheels and the goal is to preserve the proper front-to-rear stagger.
275/30R20 is a metric radial size with a wider 275-millimeter section width, a 30-series profile, and a 20-inch rim diameter. On the 2020 Mercedes-Benz CLS53 AMG, this size is used on the rear axle with the 20-inch wheel setup, giving the car a broader rear tire than the front. Current choices in this size are focused on a blackwall performance radial from Nitto in the NT555 G2 series. This is the size to verify for rear 20-inch fitment, especially on a car where the front and rear wheels must remain properly matched by diameter and position.
275/35R19 is a metric radial size that pairs a 275-millimeter section width with a 35-series profile on a 19-inch rim. For the 2020 Mercedes-Benz CLS53 AMG, it is the rear tire size used with the 19-inch wheel package, so it belongs only at the back of a 19-inch staggered setup. Available blackwall radials include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. This size gives the rear axle the wider footprint intended for the car's staggered layout, making it the right comparison point for 19-inch rear replacement.
Fitment on the 2020 Mercedes-Benz CLS53 AMG is straightforward once axle position is identified, because the front and rear use different tire sizes. Checking whether the tire is for the front or rear of the car matters just as much as confirming whether the wheels are 19-inch or 20-inch.

2020 Mercedes-Benz CLS53 AMG 4Matic Front
The 2020 Mercedes-Benz CLS53 AMG 4Matic Front uses the narrower front axle sizes in either a 19-inch or 20-inch radial configuration. Tire selection here centers on matching the wheel diameter already on the car and choosing among the available blackwall performance radial series.
The 2020 Mercedes-Benz CLS53 AMG 4Matic Rear uses the wider rear axle sizes, again split between 19-inch and 20-inch wheel packages. That means rear tire replacement should account for the staggered setup and avoid mixing a front-size casing onto the back of the vehicle.
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 2020 Mercedes-Benz CLS53 AMG?
The 2020 Mercedes-Benz CLS53 AMG uses a staggered radial setup rather than one universal tire size. Front fitments are 245/40R19 or 245/35R20, while rear fitments are 275/35R19 or 275/30R20, depending on whether the car has 19-inch or 20-inch wheels.
The practical step is to confirm both wheel diameter and axle position before choosing a tire. A front size should stay on the front and a rear size should stay on the rear, and the 19-inch and 20-inch packages should not be mixed unless the entire wheel and tire setup has been changed accordingly.
What size rim does a 2020 Mercedes-Benz CLS53 AMG use?
A 2020 Mercedes-Benz CLS53 AMG uses either 19-inch or 20-inch rims, depending on the wheel package on the car. The 245/40R19 front and 275/35R19 rear sizes pair with 19-inch rims, while the 245/35R20 front and 275/30R20 rear sizes pair with 20-inch rims.
Checking the actual wheel on the car matters more than assuming one diameter from the model name alone. Many buyers start with the door opening or sidewall, but a visual check of the wheel and the existing tire size is the safest way to avoid ordering a 19-inch tire for a 20-inch wheel, or the other way around.
Why does the 2020 Mercedes-Benz CLS53 AMG have more than one tire size?
This model has more than one tire size because it uses a staggered setup and was fitted with two different wheel diameters. The front axle uses a 245-section tire, the rear axle uses a wider 275-section tire, and each axle can be paired with either a 19-inch or 20-inch rim package.
That layout means tire selection starts with identifying whether the replacement is for the front or rear, then confirming wheel diameter. It also means a complete set should preserve the intended front-to-rear relationship, since the wider rear size is part of the car's original staggered fitment strategy and affects how the tire package is balanced across the vehicle.
Choosing the Right Tire
What should I consider when choosing a 245/35R20 tire for a 2020 Mercedes-Benz CLS53 AMG?
A 245/35R20 tire for the 2020 Mercedes-Benz CLS53 AMG should match the front axle 20-inch fitment and remain a radial construction. In this size, choices include BFGoodrich and Nitto blackwall tires, with series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2.
Selection comes down to matching the actual wheel package and comparing details such as tire series, rim-width compatibility, and load figures where they are stated. It also helps to think about how the car is used, since a front replacement should complement the rear tire setup already on the car rather than simply matching section width alone.
What brands offer tires for the 2020 Mercedes-Benz CLS53 AMG?
BFGoodrich and Nitto both offer tires for the 2020 Mercedes-Benz CLS53 AMG across its covered sizes. BFGoodrich appears in the front 19-inch and 20-inch sizes as well as the 19-inch rear size, while Nitto is available in the 20-inch front size and both rear sizes.
Brand comparison should stay secondary to getting the exact size and axle position right. Once the fitment is confirmed, the useful differences are found in the series available within that size, along with any stated rim-width range, load capacity, and how the chosen tire fits the car's current front and rear setup.
What tire series are available for the 2020 Mercedes-Benz CLS53 AMG?
The available tire series for the 2020 Mercedes-Benz CLS53 AMG include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2. Series availability varies by size, so the front and rear positions do not always share the same range of options.
That matters when replacing a pair or a full set, because a series offered in one front size may not appear in a particular rear size. Buyers should compare the exact tire size first, then see which series are offered in that position so the final choice reflects the wheel diameter and staggered layout already on the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Mercedes-Benz CLS53 AMG?
Yes, modifications can affect tire fitment on a 2020 Mercedes-Benz CLS53 AMG. Changes such as aftermarket wheels, altered offsets, suspension lowering, or body modifications can change how much room is available around a 245-section front tire or a wider 275-section rear tire, even when the nominal size remains the same.
A car with any wheel or suspension change should be checked for steering clearance, fender clearance, and rear axle room before replacement tires are chosen. The staggered layout also means front and rear positions need to be evaluated separately, since a modified setup can create rubbing or mismatch issues on one axle while the other still appears normal.
What should I inspect before driving a 2020 Mercedes-Benz CLS53 AMG on new tires?
Before driving a 2020 Mercedes-Benz CLS53 AMG on new tires, inspect the wheel diameter, verify the front and rear sizes are in the correct positions, and confirm that inflation is set properly for the installed tires. It is also smart to check for visible issues such as sidewall damage, tread irregularity, or air loss after installation.
A quick clearance check is worthwhile with the steering turned and the suspension loaded normally, especially on a staggered car with low-profile tires. Lug hardware should be secure, the wheels should seat properly, and any vibration or pull during the first miles should be addressed promptly rather than dismissed as a normal break-in issue.
What should I check before a longer drive in a 2020 Mercedes-Benz CLS53 AMG?
Before a longer drive in a 2020 Mercedes-Benz CLS53 AMG, make sure the tire sizes match the car's actual front and rear wheel setup and that all four tires are in sound condition. Pressure, tread condition, sidewall health, and any sign of uneven wear deserve attention before putting sustained highway miles on the car.
Longer trips place more emphasis on consistency across the full staggered set, so it helps to confirm that the front pair and rear pair are matched properly by size and construction. Any vibration, slow air loss, prior curb damage, or rubbing at full steering lock should be resolved ahead of time rather than discovered once the trip is underway.
