The 2012 Mercedes-Benz CL600 belongs to the final era of the big pillarless Mercedes coupe, blending long-distance luxury with the kind of V12 grand touring character that makes wheel and tire fitment especially important. On this car, the first decision is not just brand or sidewall style, but whether it is on the 19-inch or 20-inch staggered setup. Front sizes are 255/40R19 or 255/35R20, while the rear uses 275/40R19 or 275/35R20, all in radial construction. Available choices range from blackwall performance-oriented tires to RWL and redline options, so the right selection depends on preserving the car’s intended stance, wheel fit, and road manners.
Which Tire Size Is Right for The 2012 Mercedes-Benz CL600
The 2012 Mercedes-Benz CL600 uses four primary tire sizes because it is a staggered front-and-rear fitment offered in two different rim diameters. Front tires are narrower than rear tires, and the most important first step is confirming whether the car has the 19-inch or 20-inch wheel package before choosing a tire. Once wheel diameter is confirmed, the decision shifts to front versus rear sizing and then to brand, tire series, and sidewall style.
255/35R20 is a modern metric radial size in which 255 identifies the section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2012 Mercedes-Benz CL600, this size is used at the front on the 20-inch setup, where preserving the correct front-to-rear stagger matters. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, RWL, and redline sidewall treatments across several tire series. This size should be evaluated by owners confirming a 20-inch front wheel and looking for the right balance of appearance and road-use character.
255/40R19 follows the same modern metric radial format, with a 255-millimeter section width, a 40-series profile, radial construction, and a 19-inch rim diameter. This is the front tire size for a 2012 Mercedes-Benz CL600 equipped with the 19-inch wheel package, so it is part of a staggered arrangement rather than a universal all-around fitment. BFGoodrich and Pro-Trac options are available here, including blackwall, RWL, and redline styles in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Street Pro III. It is a useful size to focus on when maintaining the original 19-inch front wheel diameter and appearance direction.
275/35R20 is a modern metric radial rear size, with 275 denoting section width in millimeters, 35 showing the aspect ratio, R marking radial construction, and 20 naming the wheel diameter. On the 2012 Mercedes-Benz CL600, this size belongs on the rear when the car is fitted with 20-inch wheels, matching the wider rear stance expected from a staggered setup. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, RWL, and redline sidewall presentations depending on the tire series. This size deserves careful attention from owners who want to keep the intended rear width and visual balance of the 20-inch configuration.
275/40R19 is another modern metric radial size, using a 275-millimeter section width, a 40-series profile, radial construction, and a 19-inch rim. It serves as the rear tire size on a 2012 Mercedes-Benz CL600 with the 19-inch wheel package, so it should be paired with the matching 255/40R19 front size rather than mixed casually with 20-inch fitments. BFGoodrich and Nitto offerings are available in this size, primarily in blackwall form and across several g-Force and Nitto NT555 G2 series choices. This is the size to examine when confirming a 19-inch rear wheel and comparing performance-oriented radial options within that configuration.
Sub-model fitment on the 2012 Mercedes-Benz CL600 is straightforward in layout but still requires attention because the car uses separate front and rear sizes. The key is confirming wheel diameter first, then matching the correct front and rear pair for the Base Front and Base Rear positions.

2012 Mercedes-Benz CL600 Base Front
The 2012 Mercedes-Benz CL600 Base Front uses the narrower front fitment, either 255/40R19 or 255/35R20 depending on the wheel package. Tire selection here centers on confirming 19-inch versus 20-inch wheels, then choosing among radial options with the sidewall and series character that suits the car.
The 2012 Mercedes-Benz CL600 Base Rear uses the wider rear fitment, either 275/40R19 or 275/35R20 to match the staggered setup. That makes rear tire choice especially important for maintaining the intended stance, provided the wheel diameter and overall front-to-rear pairing are kept 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.
Best 2012 Mercedes-Benz CL600 Tires for Sale
Available 2012 Mercedes-Benz CL600 tires cover both 19-inch and 20-inch staggered fitments, with choices from BFGoodrich, Nitto, and Pro-Trac. The product grid is most useful for comparing tire series, blackwall versus RWL or redline sidewalls, and rim-width compatibility within the correct front or rear size.
Common 2012 Mercedes-Benz CL600 tire questions usually come down to staggered sizing, 19-inch versus 20-inch wheel fitment, sidewall choices, and how to choose the right radial tire for front and rear use.
Tire Size & Fitment
What tire size fits a 2012 Mercedes-Benz CL600?
The 2012 Mercedes-Benz CL600 uses a staggered radial tire setup with four primary sizes: 255/40R19 front and 275/40R19 rear on the 19-inch package, or 255/35R20 front and 275/35R20 rear on the 20-inch package. Front and rear sizes are not the same, and the wider rear tire is part of the car’s intended fitment layout.
The practical first step is confirming which wheel diameter is actually on the car. Once that is established, the correct matching front and rear pair should stay together so section width, profile, and overall stance remain consistent with the wheel setup already in place.
What size rim does a 2012 Mercedes-Benz CL600 use?
A 2012 Mercedes-Benz CL600 uses either 19-inch or 20-inch rims, depending on the wheel package. The 19-inch setup pairs 255/40R19 front with 275/40R19 rear, while the 20-inch setup pairs 255/35R20 front with 275/35R20 rear.
Rim diameter is the most important point to verify before selecting tires because the car uses two different diameters across its fitment range. A quick check of the current wheel size prevents ordering the right width and profile in the wrong diameter, especially on a staggered luxury-performance coupe like the CL600.
Why does the 2012 Mercedes-Benz CL600 have more than one tire size?
The 2012 Mercedes-Benz CL600 has more than one tire size because it uses a staggered front-and-rear arrangement and was fitted with either 19-inch or 20-inch wheels. That creates two matched size combinations rather than one uniform size set, with a narrower front tire and a wider rear tire in each package.
This matters because tire choice is tied to both wheel diameter and axle position. A buyer should confirm whether the car has 19-inch or 20-inch wheels, then make sure the front and rear tires are selected as the proper pair rather than treating all four available sizes as interchangeable options.
Choosing the Right Tire
What should I consider when choosing a 2012 Mercedes-Benz CL600 tire?
Start with the correct position and wheel diameter, since the 2012 Mercedes-Benz CL600 uses staggered front and rear sizes in either 19-inch or 20-inch form. After that, compare radial tire series, sidewall style, and rim-width specifications within the exact size needed for that corner of the car.
The best choice depends on how the CL600 is used and how the owner wants it to present. A blackwall performance-oriented tire may suit a modern appearance, while RWL or redline options can shift the visual character, provided the tire still matches the required size and wheel compatibility.
What sidewall styles are available for 2012 Mercedes-Benz CL600 tires?
Sidewall choices for the 2012 Mercedes-Benz CL600 include blackwall, RWL, and redline, depending on the tire size and series. Blackwall appears across all four primary sizes, while RWL and redline options are available in the Pro-Trac Street Pro III line for the 255/35R20, 255/40R19, and 275/35R20 sizes.
That gives the CL600 owner a real appearance decision in addition to basic fitment. Sidewall style does not replace the need to match the correct front or rear size, but it can noticeably change whether the car looks more understated, more performance-oriented, or more custom in presentation.
What brands offer tires for the 2012 Mercedes-Benz CL600?
Tires for the 2012 Mercedes-Benz CL600 are available from BFGoodrich, Nitto, and Pro-Trac across the applicable 19-inch and 20-inch radial sizes. Depending on the exact front or rear fitment, choices include several BFGoodrich g-Force series, the Nitto NT555 G2, and Pro-Trac Street Pro III offerings.
Brand selection should come after confirming the exact tire size and wheel diameter on the car. Once that is settled, the useful comparisons are tire series, sidewall treatment, rim-width compatibility, and other product details that shape how the CL600 will look and be used on the road.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Mercedes-Benz CL600?
A period-style 2012 Mercedes-Benz CL600 tire choice starts with keeping the correct staggered size pair for the car’s actual 19-inch or 20-inch wheel setup. From there, blackwall tires maintain the most understated late-model luxury coupe look, while some sizes also allow RWL or redline variations for a more personalized presentation.
Because this is a modern grand touring coupe rather than an earlier restoration-era car, appearance usually comes down to how closely the owner wants to stay with a restrained factory-era feel. Matching front and rear sizing correctly matters more than chasing a dramatic sidewall treatment that disrupts the car’s overall visual balance.
Does correct tire fitment matter for a 2012 Mercedes-Benz CL600 restoration?
Correct tire fitment matters on a 2012 Mercedes-Benz CL600 because the car’s stance depends on a staggered arrangement with specific front and rear widths tied to either 19-inch or 20-inch wheels. Using the proper size pair helps preserve the coupe’s intended proportions and avoids turning the restoration into a mixed-fitment compromise.
Appearance is only part of the equation. Keeping the correct wheel diameter, front-to-rear relationship, and suitable sidewall profile also helps maintain sensible clearance and overall presentation, which is especially important on a large Mercedes coupe where small sizing changes can alter the car’s visual character quickly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Mercedes-Benz CL600?
Yes, modifications can affect tire fitment on a 2012 Mercedes-Benz CL600, especially because the car already uses a staggered setup with different front and rear widths. Aftermarket wheels, altered offsets, suspension lowering, or body changes can all influence how a 255- or 275-section tire sits within the available space.
That makes it important to verify more than just the size stamped on the sidewall. Wheel diameter, wheel width, clearance at steering lock, and room around the fender and suspension should all be checked whenever the car no longer has its original-style wheel and suspension relationship.
What should I inspect before driving a 2012 Mercedes-Benz CL600 on new tires?
Before driving a 2012 Mercedes-Benz CL600 on new tires, inspect wheel condition, confirm the correct front and rear sizes, and check inflation pressure carefully. It is also wise to look for any suspension or alignment issues that could affect how the new radial tires wear or track once the car is back on the road.
A short test drive should be followed by another look at pressure, visible clearance, and any signs of rubbing or uneven contact. On a staggered coupe with either 19-inch or 20-inch fitment, small setup problems are easier to address early than after miles of unnecessary wear.
How often should tires on a 2012 Mercedes-Benz CL600 be inspected?
Tires on a 2012 Mercedes-Benz CL600 should be inspected regularly, not just when tread appears low. A quick visual check for cuts, bulges, cracking, unusual wear, and air loss is a smart habit, especially on a car that may see seasonal use or long periods parked between drives.
Routine inspection matters because performance-oriented radial tires can age or lose condition even when mileage stays modest. Pressure should be checked before longer trips, and any change in ride feel, steering response, or visible shoulder wear deserves attention before it turns into a larger fitment or maintenance problem.
