The 2008 Mercedes-Benz CL65 AMG sits at the top of the C216 CL lineup, combining grand touring luxury with the kind of twin-turbo V12 power that puts real demands on tire fitment. It is a large, fast coupe built to deliver high-speed stability, braking confidence, and a composed ride without giving up AMG character. Tire selection centers on a staggered radial setup, with 255/35R20 at the front and 275/35R20 at the rear on 20-inch rims. Available choices include blackwall, raised white letter, and redline sidewall treatments across several performance-oriented series. The key is matching the correct front and rear sizes while keeping wheel compatibility, appearance, and intended road use in view.
Which Tire Size Is Right for The 2008 Mercedes-Benz CL65 AMG
The 2008 Mercedes-Benz CL65 AMG uses two primary tire sizes, both in radial construction on 20-inch rims. The front and rear do not use the same size, so the first step is confirming position on the car before choosing a tire. Once that is settled, the real decision becomes comparing available tire series, sidewall styles, and wheel-width compatibility within each size.
255/35R20 is a metric radial size in which 255 identifies nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2008 Mercedes-Benz CL65 AMG, this size is used at the front, where steering response and clearance need to stay true to the car's staggered setup. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, RWL, and redline sidewall treatments depending on the tire series. This is the size to evaluate when replacing front tires while preserving the car's intended front-to-rear balance.
275/35R20 is a metric radial size with a 275-millimeter nominal section width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2008 Mercedes-Benz CL65 AMG, this is the rear tire size, giving the car the wider rear fitment that suits its high-output grand touring layout. BFGoodrich, Nitto, and Pro-Trac offerings are available here as well, with blackwall, RWL, and redline sidewall presentations across different series. This is the size to focus on when replacing rear tires and confirming that wheel width and rear clearance remain consistent with the existing setup.
Fitment on the 2008 Mercedes-Benz CL65 AMG is straightforward in one sense and very specific in another: the covered sub-model positions split between front and rear sizes. Checking which end of the car you are replacing matters more than choosing between trims, because the CL65 AMG uses a staggered tire arrangement.

2008 Mercedes-Benz CL65 AMG Base Front
The 2008 Mercedes-Benz CL65 AMG Base Front uses the narrower of the two primary radial sizes on a 20-inch rim. Front tire selection should stay focused on the correct size for steering-end fitment, then narrow down by tire series, sidewall style, and wheel-width compatibility.
The 2008 Mercedes-Benz CL65 AMG Base Rear uses the wider rear radial size on a 20-inch rim as part of the car's staggered setup. Rear tire selection should account for the proper size first, then compare available series and sidewall treatments while confirming the wheel matches the tire's intended width range.
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:

Tire Size & Fitment
What tire size fits a 2008 Mercedes-Benz CL65 AMG?
The 2008 Mercedes-Benz CL65 AMG uses a staggered tire setup with 255/35R20 at the front and 275/35R20 at the rear. Both are radial sizes mounted on 20-inch rims, and they are not interchangeable from one end of the car to the other as a normal replacement choice.
That means the first step is identifying whether the tires being replaced are on the front or rear axle. It is also worth confirming that the car still has the intended wheel setup, because aftermarket wheels or previous changes can alter width and clearance even when the rim diameter remains 20 inches.
What size rim does a 2008 Mercedes-Benz CL65 AMG use?
Both primary tire sizes for the 2008 Mercedes-Benz CL65 AMG use a 20-inch rim diameter. The front 255/35R20 and rear 275/35R20 share that diameter, so the key distinction is not wheel diameter but the difference in tire width between the front and rear positions.
Rim diameter alone is only part of the fitment picture. Wheel width still matters, especially on a staggered car like the CL65 AMG, because the available tires are intended for specific width ranges. Before replacement, confirm the actual wheel size on the car and make sure the front and rear wheels have not been mixed or changed.
Why does the 2008 Mercedes-Benz CL65 AMG have more than one tire size?
The 2008 Mercedes-Benz CL65 AMG uses more than one tire size because it has a staggered front and rear setup. The front uses 255/35R20 and the rear uses 275/35R20, giving the car a narrower steering tire in front and a wider driven tire at the rear.
For the owner, that means replacement decisions should be made by axle position rather than by looking for one universal size. Keeping the intended size relationship matters for wheel fit, vehicle balance, and clearance. If the car has had wheel, suspension, or alignment changes, confirm the current setup before choosing new tires.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Mercedes-Benz CL65 AMG?
Start with the correct position-specific size: 255/35R20 for the front and 275/35R20 for the rear. From there, compare radial tire series, sidewall style, wheel-width compatibility, and useful product details such as stated load capacity where it appears, especially on a heavy, high-powered coupe like the CL65 AMG.
The best choice depends on how the car is used and how you want it to present visually. A blackwall tire keeps a contemporary performance look, while RWL or redline versions create a more custom appearance. It also helps to confirm whether the car still rides on its original-style wheel dimensions before narrowing down options.
What sidewall styles are available for 2008 Mercedes-Benz CL65 AMG tires?
Tires for the 2008 Mercedes-Benz CL65 AMG are available in blackwall, RWL, and redline sidewall styles, depending on the size and series selected. Blackwall appears across BFGoodrich and Nitto offerings, while Pro-Trac Street Pro III adds raised white letter and redline options in both front and rear sizes.
That gives the car three distinct visual directions without changing the basic staggered fitment. Blackwall is the most understated and performance-oriented look, while RWL and redline introduce a more custom presentation. Appearance should still come second to correct front-versus-rear sizing and wheel compatibility when making the final choice.
What brands offer tires for the 2008 Mercedes-Benz CL65 AMG?
BFGoodrich, Nitto, and Pro-Trac all offer applicable tires for the 2008 Mercedes-Benz CL65 AMG in its 20-inch front and rear sizes. Across those brands, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice should be narrowed by the exact size needed at each end of the car, then by the type of presentation and specifications that matter most to you. Some options stay strictly blackwall, while others add RWL or redline styling. Wheel-width compatibility is also worth checking, especially when the car no longer has its original wheel setup.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Mercedes-Benz CL65 AMG?
A period-style choice for a 2008 Mercedes-Benz CL65 AMG starts with keeping the correct staggered 20-inch sizing, then selecting a sidewall and series that match the look you want. Blackwall maintains the restrained high-performance appearance typical of modern AMG luxury coupes, while RWL or redline options move the car toward a more personalized presentation.
Since this is a newer collector-era Mercedes, appearance decisions often come down to preserving the car's original character rather than recreating a distant vintage look. Owners aiming for close-to-original presentation should compare the tires against surviving examples, factory photography, or marque-specific references before settling on sidewall style.
Does correct tire fitment matter for a 2008 Mercedes-Benz CL65 AMG restoration?
Correct tire fitment matters on a 2008 Mercedes-Benz CL65 AMG because the car uses different front and rear sizes as part of its overall stance and road-going setup. Using the proper 255/35R20 front and 275/35R20 rear sizes helps preserve the proportions and visual balance that belong to the CL65 AMG.
Appearance is only one part of the equation. Correct sizing also helps avoid unnecessary fitment issues when the steering is turned or the suspension is loaded. On a restoration-minded car, tire choice should support both the intended look and the existing wheel dimensions rather than treating any 20-inch tire as close enough.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mercedes-Benz CL65 AMG?
Yes, modifications can affect tire fitment on a 2008 Mercedes-Benz CL65 AMG even when the vehicle still appears to use the correct 20-inch diameter. Aftermarket wheels, altered offsets, suspension lowering, alignment changes, or body modifications can change how a 255/35R20 front or 275/35R20 rear tire sits in the wheel opening.
That is why the actual wheel and suspension setup should be checked before ordering replacement tires. A tire that matches the original size still needs enough clearance at full steering lock and through suspension travel. On a staggered car, it is also important to confirm that the front and rear wheel sets have not been swapped.
What should I inspect before driving a 2008 Mercedes-Benz CL65 AMG on new tires?
Before driving a 2008 Mercedes-Benz CL65 AMG on new tires, inspect wheel condition, verify front and rear sizes, and confirm that inflation is set correctly for the tires being installed. It is also smart to look over the suspension, alignment condition, and any signs of rubbing or prior clearance issues around the fenders and inner wheel housings.
A short initial drive should be used to check for vibration, steering pull, or contact under turning and braking. Recheck pressure after the tires have settled in, and keep an eye on tread wear across the first few hundred miles. On a high-output coupe, small fitment or alignment issues tend to show up quickly.
How often should tires on a 2008 Mercedes-Benz CL65 AMG be inspected?
Tires on a 2008 Mercedes-Benz CL65 AMG should be inspected regularly, not just when tread looks low. A good routine is to check them before longer drives and periodically between trips for pressure loss, irregular wear, cuts, bulges, or sidewall damage, especially on a car with wide, low-profile 20-inch tires.
Low-use collector cars need the same attention because time and storage conditions can age tires even when mileage stays low. Look for cracking, flat spotting, or signs that the car has been sitting on underinflated tires. Consistent inspection helps catch problems early and keeps the staggered front and rear setup performing as intended.
