The 2017 Mercedes-Benz CLS63 AMG S blends the four-door coupe shape of the CLS line with the harder-edged character expected from an AMG flagship. It sits firmly in the modern high-performance luxury category, where wheel and tire fitment play a major role in both appearance and road manners. This model uses a staggered radial setup, with 255/35R19 at the front and 285/30R19 at the rear on 19-inch rims. Current choices in the front size center on blackwall BFGoodrich performance radials across several g-Force series. The key decision is matching the correct front or rear position, then confirming wheel specs and overall setup before selecting a tire.
Which Tire Size Is Right for The 2017 Mercedes-Benz CLS63 AMG S
The 2017 Mercedes-Benz CLS63 AMG S uses two primary tire sizes, both in radial construction on 19-inch rims. Fitment is position-specific rather than interchangeable, so the first step is confirming whether the tire is for the front or rear of the vehicle before comparing product choices, wheel compatibility, and overall setup.
255/35R19 is a metric radial size in which 255 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2017 Mercedes-Benz CLS63 AMG S, this size is used at the front, where precise fitment matters on a staggered setup. Available choices in this size include BFGoodrich blackwall radials from the 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 front tires and confirming wheel width compatibility.
285/30R19 is a metric radial size in which 285 is the nominal section width in millimeters, 30 is the aspect ratio, R means radial construction, and 19 indicates the wheel diameter in inches. On the 2017 Mercedes-Benz CLS63 AMG S, this size is used at the rear as part of the factory-style staggered arrangement. Its wider section and lower-profile format make rear-position confirmation especially important before choosing a replacement. Use this size only after verifying the rear wheel setup, since front and rear fitments are different on this model.
Fitment on the 2017 Mercedes-Benz CLS63 AMG S is straightforward once the tire position is identified. The covered front and rear 4Matic fitments use different sizes, so selecting the correct tire depends on confirming which end of the vehicle needs replacement.

Tire Size & Fitment
What tire size fits a 2017 Mercedes-Benz CLS63 AMG S?
The 2017 Mercedes-Benz CLS63 AMG S uses a staggered tire setup with 255/35R19 at the front and 285/30R19 at the rear. Both are radial tire sizes mounted on 19-inch rims, and each size is tied to a specific position on the vehicle rather than used universally at all four corners.
That means the first fitment step is identifying whether the tire is for the front or rear axle. A staggered setup affects width and profile, so replacement should also account for the actual wheel dimensions on the car, especially if aftermarket wheels or suspension changes have been made.
What size rim does a 2017 Mercedes-Benz CLS63 AMG S use?
The 2017 Mercedes-Benz CLS63 AMG S uses 19-inch rims with both of its primary tire sizes. The front 255/35R19 and rear 285/30R19 fitments share the same rim diameter, even though the tire widths and aspect ratios differ between the front and rear positions.
Rim diameter is only one part of the fitment picture on this model. Wheel width and the vehicle's staggered front-to-rear arrangement still need to match the tire being selected, so it is important to confirm the actual wheel setup before ordering replacement tires for either axle.
Why does the 2017 Mercedes-Benz CLS63 AMG S have more than one tire size?
The 2017 Mercedes-Benz CLS63 AMG S has more than one tire size because it uses a staggered fitment. The front position uses 255/35R19, while the rear uses 285/30R19, so the vehicle is designed around different tire widths and profiles at each end.
For the buyer, that changes the tire decision from simply choosing one size to confirming axle position first. It also means front and rear replacements should be checked carefully for wheel width, clearance, and overall balance, particularly on a high-performance sedan that may have seen wheel or suspension changes.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2017 Mercedes-Benz CLS63 AMG S?
Choosing a 255/35R19 tire for the 2017 Mercedes-Benz CLS63 AMG S starts with confirming that the tire is for the front position. Available options in this size are radial blackwall BFGoodrich tires, and they differ by g-Force series, weight, and load specification where stated.
The practical comparison points are wheel-width compatibility, intended driving use, and how closely the tire's character matches the rest of the setup on the car. A front tire choice should also be checked against the rear pairing already on the vehicle so the staggered arrangement remains consistent and predictable.
What sidewall styles are available for 2017 Mercedes-Benz CLS63 AMG S tires?
Current options for the 2017 Mercedes-Benz CLS63 AMG S in the available 255/35R19 product range use a blackwall sidewall style. That gives the tire a modern, understated appearance that suits the car's contemporary AMG presentation without adding whitewall, raised-letter, or stripe treatments.
Sidewall choice on this vehicle is less about vintage appearance and more about maintaining the clean, performance-oriented look expected from a late-model Mercedes-Benz performance sedan. The larger decision is usually the correct front or rear size and the tire series that best matches the car's wheel and use profile.
What tire series are available for the 2017 Mercedes-Benz CLS63 AMG S?
In the available 255/35R19 fitment, the 2017 Mercedes-Benz CLS63 AMG S can be matched with BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A tire series. All are radial blackwall tires built for a 19-inch rim in the correct front size format.
Series choice matters because it gives the buyer a way to compare the overall character of one tire against another without changing the fitment itself. Once the front size is confirmed, it helps to compare series details alongside rim-width suitability and the rear tire already installed on the vehicle.
Restoration & Appearance
Does correct tire fitment matter for a 2017 Mercedes-Benz CLS63 AMG S restoration?
Correct tire fitment still matters on a 2017 Mercedes-Benz CLS63 AMG S, even though the focus is more modern performance presentation than traditional restoration. The proper staggered layout uses 255/35R19 in front and 285/30R19 in the rear, both on 19-inch rims, so size accuracy remains central to the car's stance.
Appearance on a late-model AMG is closely tied to proportion, wheel fill, and preserving the intended front-to-rear visual balance. Any departure from the original-style sizing approach should be checked carefully against wheel dimensions, overall profile, and body clearance so the finished look stays cohesive.
How does tire construction affect the appearance of a restored 2017 Mercedes-Benz CLS63 AMG S?
Tire construction is straightforward on the 2017 Mercedes-Benz CLS63 AMG S because the primary fitments are radial rather than bias-ply. That keeps the visual character aligned with the car's modern design language, where low-profile metric radials and a staggered arrangement are part of the vehicle's overall appearance.
On this model, appearance differences are more likely to come from size, sidewall profile, and wheel pairing than from choosing between older and newer construction types. Keeping the correct front and rear sizes in place usually has the biggest effect on preserving the intended stance and road-ready presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz CLS63 AMG S?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz CLS63 AMG S. Even with the correct 19-inch rim diameter, aftermarket wheels, altered wheel widths, suspension changes, lowering, or alignment changes can influence how a 255/35R19 front or 285/30R19 rear tire sits in the wheel opening.
A modified setup should be checked for steering clearance, inner clearance, and fender room before replacement tires are selected. On a staggered car, changes at one axle do not always translate cleanly to the other, so front and rear fitment should be verified separately rather than assumed to match.
What should I inspect before driving a 2017 Mercedes-Benz CLS63 AMG S on new tires?
Before driving a 2017 Mercedes-Benz CLS63 AMG S on new tires, inspect the wheel condition, confirm the correct front and rear sizes, and check that each tire is mounted in the proper position. Tire pressure, visible sidewall damage, bead seating, and any signs of interference should also be reviewed before regular road use.
A short initial drive followed by a second inspection is a sensible step on a high-performance vehicle with staggered fitment. That follow-up look can reveal rubbing, uneven clearance, or air loss early, especially if the car has aftermarket wheels or has been stored for long periods between drives.
How often should tires on a 2017 Mercedes-Benz CLS63 AMG S be inspected?
Tires on a 2017 Mercedes-Benz CLS63 AMG S should be inspected regularly, not just when tread appears worn. A performance sedan with low-profile radials benefits from routine checks for air pressure, uneven wear, cuts, punctures, sidewall bulges, and any signs that the front and rear tires are not wearing evenly.
Regular inspection becomes even more important when the car is driven infrequently or stored for extended periods. Checking condition before longer trips and after seasonal storage helps catch age-related cracking, pressure loss, or wheel-related issues before they become more serious on the road.
