The 2010 Mercedes-Benz CL65 AMG sits at the intersection of grand touring luxury and hand-built AMG performance, giving the full-size CL coupe an unmistakably serious road presence. It is the kind of modern collector Mercedes that depends on correct staggered fitment to preserve both stance and driving balance. This car uses 255/35R20 tires up front and 275/35R20 tires at the rear, both in radial construction on 20-inch wheels. Available choices include blackwall performance radials along with RWL and redline presentations in select series. The key decision is matching the proper front and rear sizes while choosing a tire style that suits either original character or a more personalized look.
Which Tire Size Is Right for The 2010 Mercedes-Benz CL65 AMG
The 2010 Mercedes-Benz CL65 AMG uses two primary tire sizes, with a staggered setup that places 255/35R20 at the front and 275/35R20 at the rear. Both are radial tires for 20-inch wheels, so the first step is confirming whether you are selecting a front or rear tire. Once that is established, the real comparison is among tire series, sidewall style, and wheel-width compatibility within the correct size.
255/35R20 is a metric radial size in which 255 refers to nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2010 Mercedes-Benz CL65 AMG, this size serves the front position in the staggered setup. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, RWL, and redline sidewall treatments across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, NT555 G2, and Street Pro III. Choosing this size correctly means preserving the front fitment while comparing appearance and wheel-width suitability within the available offerings.
275/35R20 is a metric radial size where 275 indicates nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 20 identifies the wheel diameter in inches. On the 2010 Mercedes-Benz CL65 AMG, this is the rear tire size and it works with the car's staggered front-to-rear arrangement. Product choices include BFGoodrich, Nitto, and Pro-Trac tires in blackwall, RWL, and redline form, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, and Street Pro III. This size should be selected when replacing the rear tires and when confirming that the wheel width matches the tire's intended range.
Fitment is straightforward here, but it is position-specific rather than interchangeable. The covered CL65 AMG setup uses one tire size for the front and a different tire size for the rear, so confirming which end of the car you are servicing matters before choosing a tire.

2010 Mercedes-Benz CL65 AMG Base Front
The Base Front position uses the narrower of the two primary sizes in the CL65 AMG staggered setup, and it remains a 20-inch radial fitment. Tire selection here is mainly about choosing the correct front size first, then comparing sidewall style, tire series, and wheel-width compatibility among the available options.
The Base Rear position uses the wider rear tire in the staggered arrangement, also on a 20-inch radial fitment. That makes rear tire selection less about alternate sizing and more about confirming the proper rear size, then evaluating available series and sidewall treatments without mixing front and rear specifications.
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 Size & Fitment
What tire size fits a 2010 Mercedes-Benz CL65 AMG?
The 2010 Mercedes-Benz CL65 AMG uses a staggered tire setup rather than one size at all four corners. The front tire size is 255/35R20, and the rear tire size is 275/35R20. Both are radial tires designed for 20-inch wheels, so front and rear fitment need to be treated separately when replacing tires.
That means the first step is identifying whether you need front tires, rear tires, or a full set. Mixing the two sizes by mistake can upset the intended stance and fitment, so it is smart to confirm the wheel location, check the wheel width, and verify that the car has not been altered with aftermarket wheels or suspension changes before making a selection.
What size rim does a 2010 Mercedes-Benz CL65 AMG use?
The 2010 Mercedes-Benz CL65 AMG uses 20-inch rims with both of its primary tire sizes. The front 255/35R20 and rear 275/35R20 each share the same 20-inch rim diameter, even though the rear tire is wider. That common diameter keeps wheel size consistent while allowing the car to use a staggered front-and-rear tire arrangement.
Rim diameter is only one part of fitment, so the wheel width still matters when choosing among available tires. Some 255/35R20 and 275/35R20 products include stated rim-width ranges, which are worth checking against the wheels on the car, especially if the CL65 AMG has custom wheels, replacement wheels, or any changes from its original setup.
Why does the 2010 Mercedes-Benz CL65 AMG have more than one tire size?
The 2010 Mercedes-Benz CL65 AMG has more than one tire size because it uses a staggered setup, with 255/35R20 in front and 275/35R20 at the rear. That means the front and rear tires are intentionally different widths while sharing the same 20-inch rim diameter and radial construction. It is a position-specific fitment, not a case of interchangeable alternate sizes.
For the buyer, that changes the tire decision from simply choosing one size to matching the correct size to each axle. Checking the front and rear wheels individually helps prevent ordering two front sizes or two rear sizes by mistake, and it also makes it easier to compare the right sidewall style and tire series once the wheel position is confirmed.
Choosing the Right Tire
What should I consider when choosing a 255/35R20 or 275/35R20 tire for a 2010 Mercedes-Benz CL65 AMG?
Start with the correct position-specific size, since the 2010 Mercedes-Benz CL65 AMG uses 255/35R20 in front and 275/35R20 at the rear. From there, compare radial construction details such as wheel-width suitability, tire series, sidewall style, and any available load information. The available choices span several performance-oriented product lines rather than one uniform tire type.
Appearance and intended use should guide the final choice once the size is correct. A blackwall presentation keeps things understated, while RWL or redline options create a more custom look. It also helps to compare the actual wheels on the car against any stated rim-width range, particularly if the CL65 AMG has replacement wheels or a setup that differs from stock.
What sidewall styles are available for 2010 Mercedes-Benz CL65 AMG tires?
Tires for the 2010 Mercedes-Benz CL65 AMG are available in more than one sidewall style. Blackwall options appear in both the front 255/35R20 and rear 275/35R20 sizes, and select Pro-Trac Street Pro III tires are also offered with RWL and redline sidewalls. That gives the car owner a choice between a more understated look and a more pronounced visual treatment.
Sidewall style does not change the need for correct staggered sizing, so appearance choices should always come after confirming whether the tire is for the front or rear axle. Once the proper size is established, sidewall selection becomes a styling decision that can either preserve a cleaner modern presentation or add a more customized visual accent to the CL65 AMG.
What brands offer tires for the 2010 Mercedes-Benz CL65 AMG?
BFGoodrich, Nitto, and Pro-Trac all offer tires in the sizes used by the 2010 Mercedes-Benz CL65 AMG. Across the 255/35R20 front size and 275/35R20 rear size, available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III. All of these are radial tire options for 20-inch applications.
Brand choice is best handled as part of a larger fitment comparison rather than as a standalone decision. Once the correct front or rear size is confirmed, compare the available series, sidewall treatment, and wheel-width specifications that matter for the car's actual setup. That approach keeps the focus on proper fit and the appearance you want rather than simply choosing by brand name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Mercedes-Benz CL65 AMG?
Yes, modifications can affect tire fitment on a 2010 Mercedes-Benz CL65 AMG, especially because the car already uses staggered 20-inch sizing. Aftermarket wheels, altered wheel widths, different offsets, lowered suspension, or body changes can all influence how a 255/35R20 front or 275/35R20 rear tire sits in the wheel opening. Even when the tire size stays the same, the overall setup may change clearance.
That makes it important to inspect the actual wheel and suspension combination before replacing tires. Steering clearance at the front, inner clearance near suspension components, and outer clearance at the fender edge are all worth checking. A car with modifications may still use the same nominal tire size, but fitment should be verified against the current configuration rather than assumed.
What should I inspect before driving a 2010 Mercedes-Benz CL65 AMG on new tires?
Before driving a 2010 Mercedes-Benz CL65 AMG on new tires, confirm that the front and rear sizes are mounted in the correct positions and that all four tires are properly inflated. It is also wise to look over the wheels for damage, check that the tires seat evenly, and make sure there is no rubbing at full steering lock or under normal suspension movement.
A careful first inspection helps catch fitment issues early, especially on a staggered 20-inch setup. After a short initial drive, recheck air pressure and look for any signs of contact on the inner fender, liner, or suspension area. Uneven wear, vibration, or visible interference should be addressed promptly before putting more road miles on the car.
How often should tires on a 2010 Mercedes-Benz CL65 AMG be inspected?
Tires on a 2010 Mercedes-Benz CL65 AMG should be inspected regularly rather than only when tread looks low. A quick visual check before longer drives and a more thorough inspection at routine service intervals helps catch air loss, uneven wear, cuts, bulges, or sidewall damage early. That matters on a staggered setup because front and rear tires are doing different jobs and cannot simply be rotated front to back.
Consistent inspection also helps protect the wheels and suspension from problems that start with tire condition. Pay attention to changes in ride feel, steering response, or vibration, and keep an eye on tread wear patterns at both axles. Cars that are driven infrequently still need periodic checks, since age, storage conditions, and low use can affect tire condition over time.
