The 2011 Mercedes-Benz CL63 AMG blends full-size coupe luxury with the hard-edged performance character AMG was known for in the early 2010s. It is a heavy, fast grand touring car, so tire choice matters not just for appearance, but for how the car sits, responds, and puts power down. This model uses staggered radial fitments, with 255-section front tires and 275-section rear tires, offered in either 19-inch or 20-inch wheel diameters. Available choices include blackwall performance radials as well as RWL and redline options in selected sizes. The key step is confirming whether the car is on its 19-inch or 20-inch wheel setup before selecting front and rear tires.
Which Tire Size Is Right for The 2011 Mercedes-Benz CL63 AMG
The 2011 Mercedes-Benz CL63 AMG uses four primary tire sizes because fitment is staggered front to rear and also split between 19-inch and 20-inch wheel packages. The first thing to confirm is wheel diameter, since the front and rear sizes change together between those two setups. Once that is settled, the decision shifts to matching the proper front and rear pair and choosing among available radial tire series, sidewall styles, and brand options.
255/35R20 is a metric radial size with a 255-millimeter section width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2011 Mercedes-Benz CL63 AMG, this size serves the front position on the 20-inch setup and keeps the low-profile, performance-oriented stance expected from a staggered AMG fitment. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, RWL, and redline sidewall treatments depending on the tire series. This is the right front size to evaluate when the car is equipped with 20-inch wheels and the rear uses the matching 275/35R20 size.
255/40R19 is a metric radial size that indicates a 255-millimeter section width, a 40-series aspect ratio, and fitment on a 19-inch wheel. For the 2011 Mercedes-Benz CL63 AMG, it is the front tire size used with the 19-inch staggered arrangement, paired with a wider rear tire. Product choices include BFGoodrich and Pro-Trac options, with blackwall, RWL, and redline treatments available across different series. This size belongs on the front only when the car is set up with 19-inch wheels and should be matched with the corresponding 275/40R19 rear size.
275/35R20 is a metric radial size with a 275-millimeter section width, a 35-series profile, and a 20-inch rim diameter. On the 2011 Mercedes-Benz CL63 AMG, this wider size is used at the rear with the 20-inch wheel package, supporting the car’s staggered front-to-rear fitment. BFGoodrich, Nitto, and Pro-Trac offer options in this size, including blackwall, RWL, and redline presentations depending on the series. It is the rear size to consider when the car carries 20-inch wheels and should be selected alongside the matching 255/35R20 front tire.
275/40R19 is a metric radial size that uses a 275-millimeter section width, a 40-series profile, and a 19-inch wheel diameter. This size is the rear fitment for the 2011 Mercedes-Benz CL63 AMG when the car is equipped with the 19-inch staggered wheel setup. Available options come from BFGoodrich and Nitto, primarily in blackwall performance-oriented series with varying rim-width specifications and load capacities. This is the correct rear size to review only after confirming a 19-inch wheel package, since it is intended to work with the matching 255/40R19 front tire.
Sub-model fitment on the 2011 Mercedes-Benz CL63 AMG is straightforward in one sense and critical in another: the car uses a staggered setup with different front and rear tire sizes. Checking whether you are selecting for the front or rear position, and whether the car has 19-inch or 20-inch wheels, matters more than trim variation.

2011 Mercedes-Benz CL63 AMG Base Front
The Base Front position uses either a 255/35R20 or 255/40R19 radial, depending on whether the car carries the 20-inch or 19-inch wheel setup. Tire selection here centers on confirming wheel diameter first, then choosing among the available front-fitment brands, series, and sidewall treatments that match the rear setup.
The Base Rear position uses either a 275/35R20 or 275/40R19 radial, again determined by the wheel package on the car. That wider rear fitment means the rear tires should be selected as part of a proper staggered pair, with attention to wheel diameter and the overall character of the front tires being used.
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 2011 Mercedes-Benz CL63 AMG?
The 2011 Mercedes-Benz CL63 AMG uses a staggered radial setup rather than one tire size at all four corners. Front fitment is either 255/35R20 or 255/40R19, while rear fitment is either 275/35R20 or 275/40R19, depending on whether the car is equipped with 20-inch or 19-inch wheels.
That means the first step is confirming the wheel diameter actually on the car, then matching the correct front and rear pair. A CL63 AMG on 20-inch wheels needs 255/35R20 front and 275/35R20 rear, while a 19-inch setup uses 255/40R19 front and 275/40R19 rear.
What size rim does a 2011 Mercedes-Benz CL63 AMG use?
The 2011 Mercedes-Benz CL63 AMG uses either 19-inch or 20-inch rims, depending on the wheel setup on the car. The 255/40R19 and 275/40R19 sizes belong to the 19-inch arrangement, while 255/35R20 and 275/35R20 belong to the 20-inch arrangement.
Wheel diameter is the key fitment checkpoint because the tire size changes with it at both ends of the car. Checking the actual wheels before ordering matters, especially on a used CL63 AMG where wheels may have been changed or replaced since new.
Why does the 2011 Mercedes-Benz CL63 AMG have more than one tire size?
More than one tire size appears because the 2011 Mercedes-Benz CL63 AMG uses a staggered setup with narrower front tires and wider rear tires, and it was also fitted with either 19-inch or 20-inch wheel diameters. That creates four primary sizes across the two wheel packages.
The practical takeaway is that tire selection is not just a matter of year, make, and model. The front or rear position and the wheel diameter both need to be confirmed first so the correct pair is chosen and the staggered relationship is preserved.
Choosing the Right Tire
What should I consider when choosing a 2011 Mercedes-Benz CL63 AMG tire?
Start with the basics: front versus rear position, 19-inch versus 20-inch wheel diameter, and the exact tire size that belongs to that corner of the car. Every primary fitment on the 2011 Mercedes-Benz CL63 AMG is radial, so the real comparison is among tire series, sidewall styling, rim-width compatibility, load figures where stated, and overall intended use.
A grand touring AMG benefits from keeping the staggered setup consistent, so front and rear choices should complement each other rather than be chosen in isolation. It also helps to think about whether the goal is a modern blackwall performance look or a more distinctive appearance using RWL or redline sidewalls.
What sidewall styles are available for 2011 Mercedes-Benz CL63 AMG tires?
Sidewall choices for the 2011 Mercedes-Benz CL63 AMG include blackwall across all four primary sizes, with RWL and redline offerings available in 255/35R20, 255/40R19, and 275/35R20. That gives the car either a more contemporary understated look or a more pronounced custom-style presentation, depending on the tire selected.
Sidewall style does not change the need to stay with the correct front and rear sizes for the wheel package on the car. Appearance should be chosen only after fitment is settled, especially on a staggered setup where keeping the front and rear tires visually balanced makes a noticeable difference.
What brands offer tires for the 2011 Mercedes-Benz CL63 AMG?
Tires for the 2011 Mercedes-Benz CL63 AMG are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across all four primary sizes, Nitto is available in several of the performance-oriented applications, and Pro-Trac provides options in selected 19-inch and 20-inch front and rear sizes.
Brand is only one part of the decision. The more useful comparison is how each offering lines up with the correct wheel diameter, the front or rear position, the sidewall style you want, and any rim-width or load specification that matters for the specific size being selected.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Mercedes-Benz CL63 AMG?
A period-style choice for a 2011 Mercedes-Benz CL63 AMG starts with keeping the correct staggered sizing and the proper 19-inch or 20-inch wheel diameter already on the car. From there, a blackwall radial generally preserves the modern AMG character, while selected RWL or redline offerings create a more custom appearance that changes the car’s visual emphasis.
Because this is a late-model performance luxury coupe rather than an early collector car, appearance decisions often come down to how original or personalized the car is meant to look. The safest starting point is correct size and wheel match first, then sidewall style and tire series second.
How does tire construction affect the appearance of a restored 2011 Mercedes-Benz CL63 AMG?
Construction is straightforward on the 2011 Mercedes-Benz CL63 AMG because the primary fitments are radial throughout. The visible appearance difference comes less from construction type than from the tire’s profile, the way it fills a 19-inch or 20-inch wheel, and whether the sidewall is blackwall, RWL, or redline.
That makes wheel diameter and sidewall treatment more influential than a bias-ply-versus-radial decision on this particular car. Anyone pursuing a highly original presentation should compare the current wheel setup and overall look of the vehicle before choosing a sidewall style that changes its visual character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Mercedes-Benz CL63 AMG?
Yes, modifications can affect tire fitment on a 2011 Mercedes-Benz CL63 AMG, especially because the car already uses a staggered setup and two possible wheel diameters. Aftermarket wheels, altered wheel widths, suspension changes, or body modifications can all change the clearance relationship around the front and rear tires.
Checking the actual wheel diameter is only the first step on a modified car. Wheel width, offset, steering clearance, and fender space should also be verified before changing tire sizes or choosing among available tires, since a size that belongs to the model generally may still need closer review on an altered setup.
What should I inspect before driving a 2011 Mercedes-Benz CL63 AMG on new tires?
Before road use, inspect tire pressure, wheel condition, valve stems, tread and sidewalls, and confirm that the correct front and rear sizes were installed for the car’s 19-inch or 20-inch setup. On a staggered CL63 AMG, it also helps to verify that the wider rear tires and narrower front tires are mounted in the proper positions.
A quick clearance check is worthwhile as well, especially if the car has different wheels or suspension parts than it originally carried. Turning the steering from lock to lock and looking for any interference can catch problems early before the car is driven at highway speeds.
What should I check before a longer drive in a 2011 Mercedes-Benz CL63 AMG?
Before a longer drive, make sure the 2011 Mercedes-Benz CL63 AMG has the correct staggered tire sizes for its wheel package, proper inflation, and no visible cracking, bulges, cuts, or irregular wear. On a powerful grand touring coupe, even a small mismatch between front and rear sizing can undermine confidence on the road.
It is also smart to confirm that the tires have been holding air and that the wheels show no damage. A car that has sat for extended periods deserves extra attention, since collector and occasional-use vehicles can look fine at a glance while still having age or storage-related tire issues.
