The 2008 Mercedes-Benz CL600 sits at the high end of the modern grand touring coupe market, blending substantial luxury with the kind of effortless speed and road presence expected from a V12 flagship. Its long-wheelbase coupe layout and sophisticated chassis make tire choice more than a simple replacement exercise, because the car uses a staggered radial setup with different front and rear sizes and two possible wheel diameters. Front fitment is 255-width and rear fitment is 275-width, in either 19-inch or 18-inch form. Available choices range from blackwall performance radials to raised white letter and redline options on some sizes. The key is confirming whether the car is on 18-inch or 19-inch wheels before comparing appearance, series, and intended use.
Which Tire Size Is Right for The 2008 Mercedes-Benz CL600
The 2008 Mercedes-Benz CL600 uses four primary tire sizes because fitment is split by both axle position and wheel diameter. The first step is confirming whether the car is on 19-inch or 18-inch wheels, since the front and rear sizes change together as part of a staggered radial setup. Once wheel diameter is confirmed, the real decision becomes selecting the right tire series, sidewall treatment, and performance character for that front or rear position.
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 rim diameter in inches. On the 2008 Mercedes-Benz CL600, this size serves the front position when the car is equipped with 19-inch wheels. Available choices include BFGoodrich and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall treatments across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Street Pro III. This is the size to evaluate when keeping the car on its 19-inch front wheel setup.
255/45R18 is a metric radial size that uses the same 255-millimeter nominal width as the 19-inch front size, but with a 45-series profile on an 18-inch rim. On the 2008 Mercedes-Benz CL600, it applies to the front position when the car is fitted with 18-inch wheels. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline appearances depending on the tire series. This size is the correct front starting point only after confirming that the car is using the 18-inch staggered wheel package rather than the 19-inch setup.
275/40R19 is a metric radial size in which 275 is the nominal section width in millimeters, 40 is the aspect ratio, and 19 is the wheel diameter in inches. On the 2008 Mercedes-Benz CL600, this is the rear size for cars running the 19-inch staggered arrangement, giving the rear axle a wider tire than the front. BFGoodrich and Nitto options are available in this size, primarily in blackwall performance-oriented series including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. Use this size when matching a 19-inch rear wheel and preserving the front-to-rear stagger built into that setup.
275/45R18 is a metric radial size that pairs a 275-millimeter nominal width with a 45-series profile on an 18-inch rim. On the 2008 Mercedes-Benz CL600, it fills the rear position when the car is equipped with 18-inch wheels, maintaining the wider rear fitment of the staggered arrangement. The available product in this size is an M&H Racemaster radial drag rear with a blackwall sidewall and Drag Radial series construction. This size deserves extra scrutiny because tire character matters as much as size, especially on a heavy, powerful coupe that may be driven very differently than a drag-focused application.
Sub-model fitment on the 2008 Mercedes-Benz CL600 is straightforward in one sense and critical in another: the car uses separate front and rear sizes, and both positions change with wheel diameter. Checking whether the tire is for the Base Front or Base Rear position is essential before selecting a replacement.

2008 Mercedes-Benz CL600 Base Front
The 2008 Mercedes-Benz CL600 Base Front uses a 255-width radial tire, with either a 255/40R19 or 255/45R18 depending on wheel diameter. Front tire selection should focus on confirming the wheel first, then comparing available series and sidewall styles that suit the car’s road use and appearance goals.
The 2008 Mercedes-Benz CL600 Base Rear uses a wider 275-width radial tire, either 275/40R19 or 275/45R18 depending on the rear wheel package. Rear tire choice should account for the staggered setup, with attention to matching the correct wheel diameter and selecting a tire type that fits how the car is actually driven.
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)

Tire Size & Fitment
What tire size fits a 2008 Mercedes-Benz CL600?
The 2008 Mercedes-Benz CL600 uses a staggered radial tire setup, so front and rear sizes are different. Front fitment is either 255/40R19 or 255/45R18, while rear fitment is either 275/40R19 or 275/45R18. The correct combination depends on whether the car is equipped with 19-inch or 18-inch wheels.
That means the first job is not picking a brand but confirming wheel diameter and axle position. A front tire size should not be selected for the rear, and a 19-inch fitment should not be mixed with an 18-inch wheel. If the car has been modified with aftermarket wheels, verify the actual wheel size and width before comparing tire options.
What size rim does a 2008 Mercedes-Benz CL600 use?
A 2008 Mercedes-Benz CL600 uses either 19-inch or 18-inch rims, depending on the tire setup on the car. The 19-inch combination pairs 255/40R19 in front with 275/40R19 in the rear, while the 18-inch combination pairs 255/45R18 in front with 275/45R18 in the rear.
Rim diameter needs to be confirmed before any tire order is considered, because the size codes are tied directly to the wheel. It also helps to check wheel width, especially when comparing performance-oriented radials across different series. A quick look at the sidewall markings and a direct measurement of the wheel can prevent an expensive mismatch.
Why does the 2008 Mercedes-Benz CL600 have more than one tire size?
The 2008 Mercedes-Benz CL600 has more than one tire size because it uses a staggered setup with narrower tires in front and wider tires in the rear, and it appears with both 18-inch and 19-inch wheel diameters. That creates four primary sizes across the vehicle: two fronts and two rears.
This matters because the decision starts with identifying both the wheel diameter and the position on the car. The front axle uses 255-width tires and the rear uses 275-width tires, so replacing a single tire without checking placement can lead to the wrong fitment. Keeping the front and rear pairing consistent is especially important on a high-performance luxury coupe.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Mercedes-Benz CL600?
Start with the basics: confirm whether the car is on 18-inch or 19-inch wheels, then match the correct front or rear size. The 2008 Mercedes-Benz CL600 uses a staggered radial arrangement, so size, wheel diameter, and axle position all matter before brand or series is considered.
After that, compare the tire’s intended character and specifications. Some options lean toward all-season or performance street use, while others focus more narrowly on specialty use. Sidewall style may also influence the decision, especially where blackwall, redline, or raised white letter choices exist. Rim-width compatibility and load figures are worth reviewing before making a final selection.
What sidewall styles are available for 2008 Mercedes-Benz CL600 tires?
Sidewall choices for the 2008 Mercedes-Benz CL600 include blackwall across all four primary sizes, with raised white letter and redline options available on the 255/40R19 and 255/45R18 front sizes. Those appearance differences come through specific tire series rather than through a single uniform look across every size.
That means sidewall style can shape the car’s presentation, but it also needs to be matched to the actual fitment you are replacing. A blackwall tire keeps a more understated modern look, while redline or raised white letter options create a more custom or enthusiast-oriented appearance. Rear-size availability is narrower, so front and rear visual balance should be considered before mixing styles.
What brands offer tires for the 2008 Mercedes-Benz CL600?
Tires for the 2008 Mercedes-Benz CL600 are available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on the specific size. BFGoodrich covers several of the front and rear fitments, Nitto appears in selected sizes, Pro-Trac adds appearance-oriented front options, and M&H Racemaster is present in the 275/45R18 rear size.
Brand choice should be guided by the exact wheel package and how the car is used. Some series are better suited to general street driving or performance-oriented road use, while others have a more specialized purpose. Once the correct size is confirmed, compare series, sidewall style, rim-width requirements, and any load information tied to that particular tire.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Mercedes-Benz CL600?
A period-style approach for a 2008 Mercedes-Benz CL600 usually starts with keeping the correct staggered size relationship and the correct 18-inch or 19-inch wheel diameter already on the car. From there, the most restrained visual choice is typically a blackwall radial, while some front sizes also open the door to more expressive styling.
Because this is a modern luxury coupe rather than an earlier collector-era car, appearance usually comes down to preserving the car’s original character rather than chasing vintage sidewall themes. The safest path is to confirm wheel size, retain the front-to-rear stagger, and choose a tire series that suits both the look and the road use expected from the car.
How does tire construction affect the appearance of a restored 2008 Mercedes-Benz CL600?
On a 2008 Mercedes-Benz CL600, tire construction does not involve a bias-ply-versus-radial appearance decision because the primary fitments are radial. The visual difference comes more from sidewall treatment and tire series than from construction type, especially where blackwall, redline, or raised white letter options are available in certain front sizes.
That makes the appearance decision more subtle than on an older restoration. A blackwall radial keeps the car looking closer to its original-era luxury performance character, while redline or raised white letter styling creates a more personalized presentation. Matching the visual tone from front to rear is important, since the car’s staggered setup already gives the wheels a purposeful stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mercedes-Benz CL600?
Yes, modifications can affect tire fitment on a 2008 Mercedes-Benz CL600. If the car has aftermarket wheels, altered offsets, suspension changes, or body modifications, the original staggered size relationship may no longer tell the whole story. Even when the tire size looks correct on paper, wheel width and clearance can change the real fitment outcome.
A modified car should be checked at full steering lock in front and through normal suspension travel at both ends. It also helps to confirm that the wheel diameter and width match the tire being considered. On a heavy, powerful coupe, small changes in wheel setup can affect both clearance and the way the car feels on the road.
What should I inspect before driving a 2008 Mercedes-Benz CL600 on new tires?
Before driving a 2008 Mercedes-Benz CL600 on new tires, confirm that the front and rear sizes are mounted in the correct positions and that each tire matches the wheel diameter. Then inspect inflation pressure, bead seating, valve stems, and the visible clearance to suspension components, inner liners, and fender edges.
A short initial drive should be followed by another visual check for rubbing, uneven seating, or pressure loss. Since this car uses a staggered setup, it is also worth verifying that the left and right tires on each axle are matched correctly by size and series. Any vibration, pull, or interference deserves immediate attention before longer road use.
How often should tires on a 2008 Mercedes-Benz CL600 be inspected?
Tires on a 2008 Mercedes-Benz CL600 should be inspected regularly, with a quick visual check before driving and a more thorough inspection at routine service intervals. The most important items are pressure retention, tread condition, cuts, bulges, irregular wear, and any cracking that may appear as the tires age.
Low-mileage luxury coupes can spend long periods parked, so age and storage conditions matter as much as tread depth. Cars kept in garages still benefit from periodic pressure checks and sidewall inspections, especially before highway use. Looking over the tires after contact with potholes or road debris is also a smart habit on low-profile 18-inch and 19-inch fitments.
