The 2010 Mercedes-Benz CL600 sits in a distinctive grand touring niche, combining the presence of a flagship coupe with the torque-rich character expected from a top-tier V12 Mercedes-Benz of its era. Tire fitment matters here because this car uses a staggered radial setup, with different front and rear sizes and either 18-inch or 19-inch wheel diameters depending on the wheel package. That makes the choice less about vintage-style construction and more about matching the correct front and rear sizes, wheel diameter, and the kind of sidewall presentation or performance-oriented series you want. Before selecting tires, confirm the actual wheel set on the car and keep appearance, handling balance, and clearance in view.
Which Tire Size Is Right for The 2010 Mercedes-Benz CL600
The 2010 Mercedes-Benz CL600 uses four primary tire sizes, and the right one depends first on whether you are selecting for the front or rear axle and whether the car is on 18-inch or 19-inch wheels. This is a staggered radial fitment, so confirming the exact wheel diameter on the car is the first step before comparing brands, series, sidewall styles, or specialized rear-tire options.
255/40R19 is a metric radial size in which 255 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2010 Mercedes-Benz CL600, this size is part of the front fitment on 19-inch wheels. Available choices include BFGoodrich and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments appearing in this size, along with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Street Pro III. This size is worth evaluating carefully when maintaining the car's staggered setup and 19-inch wheel package.
255/45R18 is a metric radial size that uses a 255-millimeter nominal section width, a 45-series profile, and an 18-inch rim diameter. For the 2010 Mercedes-Benz CL600, it serves as the front size when the car is equipped with the 18-inch wheel setup. BFGoodrich, Nitto, and Pro-Trac options appear here, with blackwall, raised white letter, and redline sidewall choices and series including g-Force Sport Comp 2, g-Force Comp 2 AS, Nitto NT555 G2, and Street Pro III. This size becomes the correct direction only after confirming that the car is running the 18-inch front wheel combination.
275/40R19 is a metric radial size where 275 gives the nominal section width in millimeters, 40 is the aspect ratio, and 19 is the wheel diameter. On the 2010 Mercedes-Benz CL600, this size belongs to the rear position on cars using the 19-inch staggered setup. Product choices in this size include BFGoodrich and Nitto blackwall radials across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2. This is the size to focus on when preserving the wider rear fitment and wheel diameter used with the 19-inch package.
275/45R18 is a metric radial size with a 275-millimeter nominal section width, a 45-series profile, and an 18-inch rim diameter. For the 2010 Mercedes-Benz CL600, it is the rear size when the car is equipped with the 18-inch staggered arrangement. The available product in this size is an M&H Racemaster Radial Drag Rear with a blackwall sidewall and Drag Radial series character, which gives this fitment a much narrower product path than the other CL600 sizes. That makes wheel confirmation and intended use especially important before choosing this rear size.
Fitment on the 2010 Mercedes-Benz CL600 is straightforward in one sense and specific in another: the car uses distinct front and rear tire sizes rather than trim-level variation. Checking whether you are selecting for the front or rear axle, and whether the wheels are 18-inch or 19-inch, is what matters most.

2010 Mercedes-Benz CL600 Base Front
The Base Front position uses a 255-section radial tire, with either an 18-inch or 19-inch wheel depending on the wheel package. That means front tire selection centers on matching wheel diameter first, then choosing among available brands, series, and sidewall treatments within the correct size.
The Base Rear position uses a wider 275-section radial tire, again split between 18-inch and 19-inch wheel diameters. Rear selection should preserve the staggered setup, with special attention to the actual wheel size on the car and the intended use of the tire chosen.
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 questions for the 2010 Mercedes-Benz CL600 usually come down to staggered front and rear sizing, 18-inch versus 19-inch wheel fitment, radial tire selection, sidewall style, and what to inspect before putting a heavy luxury coupe back on the road.
Tire Size & Fitment
What tire size fits a 2010 Mercedes-Benz CL600?
The 2010 Mercedes-Benz CL600 uses a staggered radial fitment rather than one tire size at all four corners. Front sizes are 255/40R19 or 255/45R18, while rear sizes are 275/40R19 or 275/45R18, depending on whether the car has 19-inch or 18-inch wheels.
The key is matching both axle position and wheel diameter before choosing a tire. A front 255-section size should not be confused with the wider rear 275-section size, and an 18-inch tire cannot be used on a 19-inch wheel. Confirm the actual wheel set on the car, especially if it has ever been changed from its original-style configuration.
What size rim does a 2010 Mercedes-Benz CL600 use?
A 2010 Mercedes-Benz CL600 uses either 18-inch or 19-inch rims, depending on the tire size fitted to the car. The 255/45R18 and 275/45R18 sizes pair with 18-inch wheels, while the 255/40R19 and 275/40R19 sizes pair with 19-inch wheels.
Wheel diameter should be confirmed before anything else because it determines which tire sizes are even possible. This car also uses different front and rear widths, so the wheel setup matters beyond diameter alone. Looking at the sidewall size marking and measuring the actual wheel package is smart if the CL600 has aftermarket wheels or a mixed replacement history.
Why does the 2010 Mercedes-Benz CL600 have more than one tire size?
The 2010 Mercedes-Benz CL600 has more than one tire size because it uses a staggered setup and was fitted with either an 18-inch or 19-inch wheel package. That creates two front sizes and two rear sizes: one pair for 18-inch wheels and one pair for 19-inch wheels.
That does not mean every size fits every position on the car. The practical decision is to identify the axle and wheel diameter first, then choose within the correct size for that location. Once that is settled, attention can shift to brand, tire series, sidewall appearance, and whether the car is being kept close to a factory-style presentation or tailored to a different use.
Choosing the Right Tire
What should I consider when choosing a 2010 Mercedes-Benz CL600 tire?
Start with the correct axle position and wheel diameter, because the 2010 Mercedes-Benz CL600 uses different front and rear sizes and either 18-inch or 19-inch wheels. After that, compare construction, tire series, sidewall style, rim-width suitability, and load figures where they are given for the exact size you need.
This is a heavy, high-speed grand touring coupe, so tire selection should support the way the car is actually used. Some sizes offer broader choices across BFGoodrich, Nitto, and Pro-Trac, while the 275/45R18 rear path is much narrower. Keeping the staggered layout intact and matching the tire to the wheel is more important than chasing appearance alone.
What sidewall styles are available for 2010 Mercedes-Benz CL600 tires?
Sidewall choices for the 2010 Mercedes-Benz CL600 include blackwall, raised white letter, and redline, depending on the size selected. The widest variety appears in the front sizes, where Pro-Trac Street Pro III adds raised white letter and redline alternatives alongside more contemporary blackwall performance radials.
Sidewall style affects the visual character of the car much more than the fitment basics. A blackwall keeps a more understated modern look, while raised white letter and redline treatments create a stronger custom or muscle-era visual cue. The important thing is to choose the sidewall only after the correct tire size and wheel diameter have been confirmed.
What brands offer tires for the 2010 Mercedes-Benz CL600?
Tires for the 2010 Mercedes-Benz CL600 are available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. Brand availability depends on the exact size, with the 255/40R19, 255/45R18, and 275/40R19 sizes offering the broadest spread of choices and the 275/45R18 rear size being much more specialized.
Brand comparison is most useful after the fitment is narrowed down to the exact front or rear size. At that point, look at tire series, sidewall style, rim-width details, and the intended use of the car rather than assuming every brand offers the same character. The narrowest product range appears at the 275/45R18 rear, so selection there requires extra attention.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Mercedes-Benz CL600?
A period-style 2010 Mercedes-Benz CL600 usually starts with keeping the correct staggered sizing and wheel diameter intact, then choosing a tire that supports the visual tone you want. Blackwall performance radials maintain a more original-era luxury coupe look, while some front sizes also open the door to redline or raised white letter alternatives.
Appearance should be balanced against how the car is actually driven and how closely it is being kept to a factory-inspired presentation. Since sidewall treatments can shift the look significantly, it helps to decide whether the goal is subtle authenticity, a custom edge, or a more performance-themed stance. Matching front and rear proportions remains central to the car's visual balance.
How does tire construction affect the appearance of a restored 2010 Mercedes-Benz CL600?
On a 2010 Mercedes-Benz CL600, construction is less about bias-ply versus radial and more about the visual character of the radial tire chosen. This car uses radial sizes throughout, so the appearance difference usually comes from series styling and sidewall treatment rather than from a change in basic construction type.
That makes details like blackwall, raised white letter, and redline more important than many buyers first expect. A blackwall keeps the coupe more restrained and formal, while the other treatments introduce a stronger enthusiast or custom flavor. For a restoration-oriented result, preserve the correct front and rear size relationship before making any appearance-driven sidewall decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Mercedes-Benz CL600?
Yes. Modifications can change tire fitment on a 2010 Mercedes-Benz CL600, especially if the car has aftermarket wheels, altered offsets, suspension changes, or lowering work. Because the CL600 uses a staggered setup and two possible wheel diameters, even a small departure from the original-style wheel package can change what clears properly.
A modified car should be checked for wheel diameter, wheel width, tire-to-suspension clearance, and fender or inner-liner space before finalizing a replacement tire. Steering travel and rear clearance both matter. On a car with prior changes, the size printed on the current tire is useful, but the wheel itself and the available space are what need confirmation.
What should I inspect before driving a 2010 Mercedes-Benz CL600 on new tires?
Before driving a 2010 Mercedes-Benz CL600 on new tires, inspect the wheels for damage, confirm the correct front and rear sizes are installed, and check inflation pressure carefully. It also makes sense to look over suspension and alignment condition, since a heavy grand touring coupe can reveal problems quickly through uneven wear or poor straight-line behavior.
A short road test should follow, with attention to vibration, rubbing, pull, or any sign that the staggered setup has been mismatched. Recheck pressure after the tires have settled in and look again for clearance at full steering lock if front wheels or tire sizes were changed previously. Catching those issues early protects both the tire and the car.
What should I check before a longer drive in a 2010 Mercedes-Benz CL600?
Before a longer drive, verify that the 2010 Mercedes-Benz CL600 has the correct front and rear tire sizes, stable pressure, sound tread condition, and no visible cuts, bulges, or sidewall damage. On a lower-use luxury coupe, age and storage condition deserve as much attention as tread depth, especially if the car spends long periods parked.
It is also worth confirming that the tires are wearing evenly and that nothing is contacting the tire under steering or suspension movement. A longer trip puts more heat and load into the setup, so any weak point becomes more obvious. Checking the spare strategy, roadside tools, and overall wheel condition adds useful peace of mind before departure.
