The 2016 Mercedes-Benz CLS550 blends four-door luxury with the long-hood, coupe-like profile that made the CLS a standout in modern Mercedes-Benz design. In this generation, the car carries a distinctly performance-oriented stance, and its tire setup reflects that with a staggered front-and-rear radial fitment. Front positions use either 255/35R19 or 255/40R18, while the rear uses either 285/30R19 or 285/35R18, so wheel diameter is the first thing to confirm. Available choices lean toward blackwall performance radials from BFGoodrich and Nitto, with differences in tire series and rim-width compatibility that matter when replacing a matched set.
Which Tire Size Is Right for The 2016 Mercedes-Benz CLS550
The 2016 Mercedes-Benz CLS550 uses four primary tire sizes, and the right one depends on both wheel diameter and axle position. Front tires are 255-section sizes, while rear tires are wider 285-section sizes, with fitment split between 18-inch and 19-inch rims. Before choosing a tire, confirm whether the car is wearing its 18-inch or 19-inch wheels and make sure the front and rear sizes stay properly matched.
255/35R19 is a metric radial size with a 255-millimeter section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2016 Mercedes-Benz CLS550, this size serves the front axle on 19-inch wheel setups and supports the car's low-profile, performance-oriented stance. Available choices in this size come from BFGoodrich in blackwall form across 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 the car has 19-inch front wheels and you want to compare series character, load specification, and rim-width compatibility within the correct fitment.
255/40R18 is a metric radial size that uses the same 255-millimeter nominal width as the 19-inch front option, but with a 40-series profile on an 18-inch rim. For the 2016 Mercedes-Benz CLS550, it is the front tire size used with 18-inch wheel packages. BFGoodrich offers this size in blackwall form through the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, giving the buyer several performance-radial choices within the same basic front fitment. It is the right starting point when replacing front tires on an 18-inch setup and comparing tire series without changing wheel diameter.
285/30R19 is a wide metric radial with a 285-millimeter section width, a 30-series profile, and a 19-inch rim diameter. On the 2016 Mercedes-Benz CLS550, this size belongs at the rear when the car is equipped with 19-inch wheels, creating the staggered fitment that matches the narrower 255/35R19 front. Its role is not interchangeable with the front tire size, so rear-wheel width and overall matched-set setup need to stay consistent. Choose this size only when confirming a 19-inch rear wheel package and maintaining the proper front-to-rear relationship on the car.
285/35R18 is a metric radial rear size with a 285-millimeter width, a 35-series profile, and an 18-inch rim diameter. It is the rear fitment for 2016 Mercedes-Benz CLS550 models running the 18-inch staggered setup, pairing with 255/40R18 on the front. In available product choices, this size appears as a blackwall Nitto NT555 G2, giving the rear axle a clear performance-radial option with its own rim-width range and load specification. This is the size to review when replacing rear tires on an 18-inch car and keeping the staggered package aligned with the correct wheel diameter.
Fitment is straightforward across the covered CLS550 configurations because both Base and 4Matic models use the same front-and-rear tire pattern. The important step is confirming whether the car has 18-inch or 19-inch wheels, since front and rear sizes both change with rim diameter.

2016 Mercedes-Benz CLS550 4Matic Front
The 2016 Mercedes-Benz CLS550 4Matic Front uses a 255-section radial tire, with fitment split between 255/35R19 and 255/40R18 depending on wheel diameter. Tire selection here starts with confirming the front rim size, then comparing available blackwall performance-radial options within the correct series and wheel-width range.
The 2016 Mercedes-Benz CLS550 4Matic Rear uses the wider rear half of the staggered setup, either 285/30R19 or 285/35R18. That means the rear tire choice should stay matched to the car's actual wheel diameter and front fitment rather than treating the rear size as a stand-alone substitution.
The 2016 Mercedes-Benz CLS550 Base Front follows the same front fitment pattern as the 4Matic, using either 255/35R19 or 255/40R18 radial tires. The practical decision is confirming whether the car wears 18-inch or 19-inch front wheels and then choosing among the available blackwall performance series in that exact size.
The 2016 Mercedes-Benz CLS550 Base Rear uses a staggered rear fitment of either 285/30R19 or 285/35R18. Rear replacement should be approached as part of the full axle pairing, with wheel diameter and the corresponding front size checked first so the overall setup remains consistent.
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.

These FAQs focus on the exact tire sizes used on the 2016 Mercedes-Benz CLS550, including staggered front-and-rear fitment, 18-inch versus 19-inch wheel confirmation, product selection, and the checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2016 Mercedes-Benz CLS550?
The 2016 Mercedes-Benz CLS550 uses a staggered radial setup rather than one universal tire size. Front fitment is either 255/35R19 or 255/40R18, and rear fitment is either 285/30R19 or 285/35R18. The 19-inch package pairs 255/35R19 front with 285/30R19 rear, while the 18-inch package pairs 255/40R18 front with 285/35R18 rear.
That makes wheel diameter the first thing to confirm before ordering replacements. The front and rear sizes are not interchangeable, and the car should keep a matched staggered setup based on its actual wheels. A quick check of the tire sidewall and wheel diameter usually settles the question before comparing brands, tire series, or load specifications.
What size rim does a 2016 Mercedes-Benz CLS550 use?
The 2016 Mercedes-Benz CLS550 uses either 18-inch or 19-inch rims, depending on the wheel package on the car. The 255/40R18 and 285/35R18 sizes are built for 18-inch rims, while 255/35R19 and 285/30R19 are built for 19-inch rims. Both Base and 4Matic configurations follow that same basic front-and-rear pattern.
Rim diameter needs to be confirmed before anything else because the CLS550 has different front and rear tire sizes at each wheel diameter. It also helps to check wheel width when comparing replacement tires, especially on a staggered performance setup. If the car has been fitted with aftermarket wheels, verify the actual wheel dimensions instead of relying on model name alone.
Do all 2016 Mercedes-Benz CLS550 sub-models use the same tire size?
Base and 4Matic versions of the 2016 Mercedes-Benz CLS550 follow the same fitment pattern, but that pattern still includes multiple sizes. Both use 255-section front tires and 285-section rear tires, with the exact size changing according to whether the car has 18-inch or 19-inch wheels. So the sub-model does not create a different tire strategy by itself.
The more important distinction is front versus rear and 18-inch versus 19-inch wheel diameter. A buyer choosing tires should confirm which wheels are actually on the car rather than assuming every CLS550 uses one set of dimensions. That matters especially when replacing only two tires, because the correct front or rear companion size still has to match the existing setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Mercedes-Benz CLS550?
Start with the exact axle position and wheel diameter, because the 2016 Mercedes-Benz CLS550 uses staggered sizes and two different rim diameters. Once the correct size is confirmed, compare construction, rim-width range, load specification, and tire series. The available choices are all radial performance tires, but they still differ in details that affect how well they suit the wheel and intended use.
A front 255 size and rear 285 size should stay in their proper positions, and the 18-inch and 19-inch packages should not be mixed casually. Beyond size, the decision usually comes down to the tire line that best matches the car's use, whether that means an all-season-oriented option or a more performance-focused series. Wheel measurements and existing setup should guide that final choice.
What sidewall styles are available for 2016 Mercedes-Benz CLS550 tires?
The available tires for the 2016 Mercedes-Benz CLS550 are offered in blackwall form. That applies across the BFGoodrich front-size choices and the Nitto rear-size option shown for the 18-inch rear fitment. For this vehicle, the sidewall decision is simpler than it is on many vintage applications because the main variation comes from tire series and size, not decorative sidewall treatments.
That simplicity helps keep the focus on correct staggered fitment and wheel compatibility. Instead of choosing between whitewalls, redlines, or similar appearance options, the buyer is comparing modern blackwall performance radials within the correct front or rear size. It is still worth checking that the replacement tire's overall presentation matches the look you want, especially if the car has aftermarket wheels.
What brands offer tires for the 2016 Mercedes-Benz CLS550?
BFGoodrich and Nitto are represented in the available tire choices for the 2016 Mercedes-Benz CLS550. BFGoodrich covers the 255/35R19 and 255/40R18 front sizes through several g-Force series, while Nitto appears in the 285/35R18 rear size with the NT555 G2. Brand choice here is tied closely to the exact size and axle position rather than being the same across all four fitments.
That means the practical comparison starts with size and wheel diameter, then moves to the brand and series available in that fitment. A buyer replacing only front tires may have different brand options than someone replacing rear tires, especially on the 18-inch setup. Matching the correct size to the correct wheel remains the first priority before comparing brand-specific specifications.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Mercedes-Benz CLS550 restoration or preservation project?
Yes, correct tire fitment still matters on a 2016 Mercedes-Benz CLS550 even though it is a newer collector-era Mercedes compared with classic restorations. The car's visual stance depends heavily on its staggered front-and-rear setup, and the difference between 18-inch and 19-inch packages changes that presentation. Using the proper front and rear sizes helps preserve the intended proportions of the car.
Appearance is only part of the picture. Correct fitment also supports proper wheel compatibility and avoids introducing unnecessary clearance questions by mixing sizes or diameters casually. Anyone aiming for a preservation-minded result should confirm the wheel package currently on the car and keep tire choices aligned with that setup before focusing on brand or tire series.
How does tire construction affect the appearance of a 2016 Mercedes-Benz CLS550?
On the 2016 Mercedes-Benz CLS550, tire construction is straightforward because the primary fitment is radial throughout. That keeps the appearance discussion centered less on bias-ply-versus-radial differences and more on profile, wheel diameter, and sidewall shape within the correct metric sizes. A low-profile 19-inch setup presents a different visual character than the 18-inch package even when both are correct fitments.
For an owner focused on preserving the car's intended look, the key is maintaining the proper front and rear size pairing for the wheel package already in use. Blackwall styling keeps the presentation modern and restrained, while the exact tire series influences the final look more subtly. The safest approach is to confirm the existing wheel diameter before choosing replacement tires on appearance alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mercedes-Benz CLS550?
Yes, modifications can affect tire fitment on a 2016 Mercedes-Benz CLS550, especially because the car already uses a staggered setup with low-profile radial sizes. Changes such as aftermarket wheels, different wheel widths, offset changes, suspension lowering, or body alterations can all influence whether the intended front and rear tire sizes have proper clearance and support on the wheel.
A car that no longer has its original wheel setup should be measured rather than assumed to match standard CLS550 fitment. Check the actual rim diameter, wheel width, and tire-to-fender or tire-to-suspension clearance before replacing tires. That step matters most when moving between 18-inch and 19-inch packages or when only one axle is being updated after earlier modifications.
What should I inspect before driving a 2016 Mercedes-Benz CLS550 on new tires?
Before road use, inspect the wheel and tire installation carefully on all four corners. Confirm that the front tires are the correct 255 size, the rear tires are the correct 285 size, inflation is set properly for the application, and there is no visible interference at full steering lock or through normal suspension travel. Lug torque, valve condition, and overall mounting quality also deserve attention.
A short initial drive followed by a recheck is a smart habit on a staggered setup like the CLS550's. Watch for vibration, rubbing, uneven seating, or any sign of air loss after installation. It also helps to inspect the old tires before disposal, since irregular wear can point to alignment or suspension issues that may affect the life of the new set.
How often should tires on a 2016 Mercedes-Benz CLS550 be inspected?
Tires on a 2016 Mercedes-Benz CLS550 should be inspected regularly, not just when tread appears low. A visual check for cracking, punctures, bulges, cuts, irregular wear, and pressure loss is worthwhile every month and before longer drives. Because the car uses low-profile staggered sizes, uneven wear or impact damage can be easier to overlook than on taller sidewall applications.
Inspection becomes even more important if the car is driven infrequently or stored for long periods. Performance-oriented radial tires can age out long before they wear out, so tread depth alone is not enough. Keeping the tires clean, properly inflated, and away from prolonged heat, sunlight, and ozone sources helps preserve condition between drives and supports more predictable road behavior.
