The 2016 Mercedes-Benz CLS400 blends four-door luxury with coupe-like proportions, making tire fitment more than a simple replacement decision. Its stance and road manners depend on a staggered radial setup, with narrower front sizes and wider rear sizes, and wheel diameter changes the exact fitment. This CLS400 uses 18-inch or 19-inch metric radial tire sizes depending on the wheel package, so the first step is confirming whether the car has the 18-inch or 19-inch arrangement. Available choices center on performance-oriented blackwall radials from BFGoodrich and Nitto. For owners focused on preserving the car’s intended balance, matching the correct front and rear sizing is just as important as selecting the right tire series.
Which Tire Size Is Right for The 2016 Mercedes-Benz CLS400
The 2016 Mercedes-Benz CLS400 uses four primary tire sizes because fitment is staggered front to rear and also varies between 18-inch and 19-inch wheel setups. The first thing to confirm is wheel diameter, then whether you are selecting a front or rear tire. Once that is established, the decision becomes choosing the right radial tire within the correct size, rim-width range, and performance-oriented product lineup.
255/35R19 is a metric radial size with a 255-millimeter section width, a 35-series profile, and a 19-inch rim diameter. On the 2016 Mercedes-Benz CLS400, this size serves the front position on the 19-inch staggered setup, where maintaining the proper front-to-rear balance matters. 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 the goal is to stay with the intended low-profile radial fitment.
255/40R18 is a metric radial size that uses a 255-millimeter section width, a 40-series aspect ratio, and an 18-inch rim. For the 2016 Mercedes-Benz CLS400, it is the front tire size on the 18-inch staggered arrangement, pairing with a wider rear tire for the car’s planted look and handling balance. BFGoodrich offers this size in blackwall performance-oriented lines including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. It is the right front-size path to review when the car retains 18-inch wheels and needs a properly matched radial setup.
285/30R19 is a metric radial size with a 285-millimeter section width, a 30-series profile, and a 19-inch rim diameter. On the 2016 Mercedes-Benz CLS400, this is the wider rear size used with the 19-inch staggered wheel package, so it should be matched with the corresponding 19-inch front size rather than selected in isolation. Its low-profile format reflects the larger-wheel setup and the rear-biased width typical of this application. Choosing this size starts with confirming the rear wheel diameter and making sure the car still uses the staggered arrangement it was set up around.
285/35R18 is a metric radial tire size with a 285-millimeter section width, a 35-series profile, and an 18-inch rim diameter. It serves the rear position on the 18-inch staggered setup for the 2016 Mercedes-Benz CLS400, where the wider rear tire complements the narrower front size. In this fitment, Nitto offers a blackwall NT555 G2 option with a broader rear-wheel rim-width range than the front sizes use. This size is the one to focus on when the car has 18-inch rear wheels and the goal is to maintain the correct staggered radial relationship.
Fitment on the 2016 Mercedes-Benz CLS400 is straightforward once the car is broken down by front and rear positions. Both Base and 4Matic versions follow the same staggered pattern, but the correct tire still depends on wheel diameter and whether the tire is for the front or rear axle.

2016 Mercedes-Benz CLS400 4Matic Front
The 2016 Mercedes-Benz CLS400 4Matic Front uses either the 255/35R19 or 255/40R18 radial size, depending on which wheel package is on the car. Tire selection here starts with confirming 18-inch versus 19-inch front wheels, then choosing among the available blackwall performance radial options in the matching size.
The 2016 Mercedes-Benz CLS400 4Matic Rear uses either 285/30R19 or 285/35R18, matching the staggered rear fitment to the wheel diameter on the vehicle. Rear tire choice should stay aligned with the front setup so the car keeps the intended staggered sizing rather than mixing 18-inch and 19-inch fitments.
The 2016 Mercedes-Benz CLS400 Base Front follows the same front-tire pattern as the 4Matic version, using either 255/35R19 or 255/40R18 in radial construction. The practical decision is confirming the actual front wheel diameter and then comparing the available BFGoodrich series that suit the car’s preferred road use and tire character.
The 2016 Mercedes-Benz CLS400 Base Rear uses the wider rear staggered sizes, either 285/30R19 or 285/35R18, depending on the wheels installed. That means rear-tire selection should be treated as part of a matched front-and-rear package, with wheel size and rear rim-width compatibility checked before choosing a replacement.
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.

Owners usually need to sort out front versus rear sizing first, then confirm 18-inch or 19-inch wheels. The questions below cover staggered fitment, rim size, tire selection, appearance, and the checks worth making before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2016 Mercedes-Benz CLS400?
The 2016 Mercedes-Benz CLS400 uses a staggered radial tire setup rather than one size at all four corners. Front fitment is 255/35R19 or 255/40R18, while rear fitment is 285/30R19 or 285/35R18. The correct combination depends on whether the car has the 19-inch or 18-inch wheel package.
That means the first step is not just reading the sidewall, but confirming both wheel diameter and axle position. A front tire and a rear tire are not interchangeable on this application, and the 18-inch and 19-inch setups should not be mixed casually. If the car has aftermarket wheels, verify the actual installed wheel size before selecting replacements.
What size rim does a 2016 Mercedes-Benz CLS400 use?
The 2016 Mercedes-Benz CLS400 uses either 18-inch or 19-inch rims, depending on the wheel setup on the car. The 255/40R18 front and 285/35R18 rear sizes fit 18-inch rims, while the 255/35R19 front and 285/30R19 rear sizes fit 19-inch rims.
Rim diameter should be confirmed before anything else because the tire sizes are tied directly to it. Wheel width also matters once the correct diameter is established, especially on the wider rear tires. If the car has been changed from its original wheel package, check the stamping on the wheel or verify the installed tire size before choosing a new set.
Do all 2016 Mercedes-Benz CLS400 sub-models use the same tire size?
Base and 4Matic versions of the 2016 Mercedes-Benz CLS400 follow the same front and rear size pattern. Both use either 255-width front tires with 285-width rear tires on 18-inch wheels or the same staggered layout on 19-inch wheels, depending on the wheel package installed.
The important distinction is front versus rear and 18-inch versus 19-inch, not Base versus 4Matic. That simplifies sub-model selection, but it does not remove the need to confirm the actual wheel setup on the car. Matching the correct front and rear sizes helps preserve proper staggered fitment and avoids ordering the right width on the wrong rim diameter.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2016 Mercedes-Benz CLS400?
A 255/35R19 tire on the 2016 Mercedes-Benz CLS400 is a front-position fitment, so the main considerations are correct size, radial construction, and compatibility with the car’s 19-inch staggered setup. Available choices in this size include BFGoodrich blackwall tires in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series.
Selection usually comes down to the kind of tire character you want within the correct fitment, along with wheel-width suitability and load details where they are published. Because this size belongs on the front axle of the 19-inch arrangement, it should be paired with the corresponding 285/30R19 rear size rather than treated as a standalone all-around fitment.
What brands offer tires for the 2016 Mercedes-Benz CLS400?
BFGoodrich and Nitto both appear in the available tire choices for the 2016 Mercedes-Benz CLS400. BFGoodrich covers the 255/35R19 and 255/40R18 front sizes through several g-Force series, while Nitto appears in the 285/35R18 rear fitment with the NT555 G2.
Brand choice matters less than making sure the exact front or rear size matches the wheel diameter already on the car. After that, compare the tire series, blackwall presentation, published load figures where available, and the rim-width range that suits your wheel. That approach keeps the focus on correct fitment first and product character second.
What tire series are available for the 2016 Mercedes-Benz CLS400?
The available series for the 2016 Mercedes-Benz CLS400 include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. These are all radial blackwall tire options, but they are spread across different fitment sizes rather than appearing in every size used on the car.
That makes it important to start with the exact tire size and axle position before comparing series names. A front 255-size and a rear 285-size do different jobs on this staggered setup, and not every series is available at both ends. Once the correct size is confirmed, the series comparison becomes a practical way to narrow the choices.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Mercedes-Benz CLS400?
A period-style approach for a 2016 Mercedes-Benz CLS400 usually means keeping the original staggered proportions and the wheel diameter the car already uses. That points back to the correct 18-inch or 19-inch front-and-rear radial size combination rather than changing to a non-matching fitment that alters the car’s stance.
Since the available products here are blackwall radials, appearance choice is more about preserving the car’s clean modern luxury-performance look than recreating an older sidewall treatment. Owners chasing exact showroom-era presentation should also confirm whether the car still wears its original wheel package, because wheel design and diameter influence the finished look as much as the tire itself.
Does correct tire fitment matter for a 2016 Mercedes-Benz CLS400 restoration?
Correct tire fitment matters on a 2016 Mercedes-Benz CLS400 because the car uses staggered front and rear sizing, and that proportion is part of its intended appearance and road stance. Using the proper 18-inch or 19-inch combination keeps the visual balance of the wider rear tire and lower-profile wheel package intact.
A restoration-oriented tire decision should look beyond simple diameter and include front-versus-rear placement, sidewall profile, and whether the car still has the wheels it was set up around. Even on a newer collector car, a mismatched tire setup can change both appearance and fitment. Matching the correct size family is the cleanest starting point.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mercedes-Benz CLS400?
Yes, modifications can affect tire fitment on a 2016 Mercedes-Benz CLS400, especially because it uses staggered front and rear sizes tied to either 18-inch or 19-inch wheels. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all change how much room the tire has at the fender, suspension, and steering points.
A car that still uses stock-sized tires may still need extra checking if the wheel itself has changed. Before replacing tires, confirm the installed wheel diameter and width, then look at clearance with the steering turned and the suspension loaded. On a staggered setup, front and rear should be checked separately because they do not share the same size.
What should I inspect before driving a 2016 Mercedes-Benz CLS400 on new tires?
Before driving a 2016 Mercedes-Benz CLS400 on new tires, inspect wheel condition, confirm that each tire matches the correct front or rear position, and verify inflation pressure once the tires are mounted. It is also smart to check for uneven suspension wear, damaged wheels, and any signs that the previous tires rubbed under steering or suspension movement.
A short, careful road test helps confirm that the car tracks cleanly and that there is no contact at full steering lock or over bumps. Because this Mercedes uses a staggered layout, double-check that the front pair and rear pair are not accidentally swapped. Rechecking pressure after the initial drive is a sensible final step.
How often should tires on a 2016 Mercedes-Benz CLS400 be inspected?
Tires on a 2016 Mercedes-Benz CLS400 should be inspected regularly, not just when tread looks worn. A quick visual check for cuts, bulges, cracking, punctures, and uneven wear is worthwhile before routine driving, and a more thorough inspection should happen any time the car has been stored, driven over rough pavement, or feels different on the road.
Low-use luxury cars can develop age-related tire issues even when tread depth still appears acceptable. Pay close attention to shoulder wear, air loss, and any signs of inner-edge wear that may be harder to see on wide low-profile tires. Routine pressure checks matter as much as visual inspection, especially on staggered setups where front and rear sizes differ.
