2013 Mercedes-Benz CL63 AMG Tires

The 2013 Mercedes-Benz CL63 AMG uses a staggered radial tire setup, so front and rear sizes are different. Front fitment is either 255/40R19 or 255/35R20, while rear fitment is either 275/40R19 or 275/35R20. The correct combination depends on whether the car is equipped with 19-inch wheels or 20-inch wheels.

That means the first fitment check is not simply the year and model, but also the wheel package and axle position. A CL63 AMG with 19-inch wheels needs the 19-inch front-and-rear pair, while a 20-inch-equipped car needs the 20-inch pair. Mixing diameters or using the front size on the rear can upset the staggered setup, so checking the actual wheels on the car matters before ordering.

The 2013 Mercedes-Benz CL63 AMG uses either 19-inch or 20-inch rims, depending on the wheel setup. The 255/40R19 front and 275/40R19 rear sizes fit 19-inch wheels, while the 255/35R20 front and 275/35R20 rear sizes fit 20-inch wheels.

Wheel diameter needs to be confirmed at both ends of the car before selecting tires, especially on a performance coupe with a staggered arrangement. It also helps to verify wheel width, since available tires carry different approved rim-width ranges by size. If the car has aftermarket wheels, measure and inspect the actual setup rather than assuming it still carries its original diameter.

The 2013 Mercedes-Benz CL63 AMG has more than one tire size because it uses a staggered layout and was fitted with either a 19-inch or 20-inch wheel package. Front tires are 255-section widths and rear tires are 275-section widths, with profile changes tied to wheel diameter.

This matters because tire selection starts with identifying both the wheel size and whether the tire is for the front or rear. Two sizes may look close on paper, but they are not interchangeable across different rim diameters or axle positions. Matching the correct pair helps preserve the intended proportions and avoids clearance or wheel-compatibility issues during replacement.

Start with the exact axle position and wheel diameter, since the 2013 Mercedes-Benz CL63 AMG uses different front and rear sizes in either a 19-inch or 20-inch setup. After size is confirmed, compare tire construction, rim-width compatibility, load figures where stated, sidewall style, and the intended character of the tire series.

A buyer focused on a clean modern presentation may prefer a blackwall performance radial, while someone looking for a more distinctive custom look may consider RWL or redline options where available. It also helps to compare product weight and approved wheel-width range within the correct size. Those details become especially important if the car has non-stock wheels or is driven regularly.

Sidewall choices for the 2013 Mercedes-Benz CL63 AMG include blackwall, RWL, and redline, depending on the tire size and series selected. Blackwall appears across the full size range, while RWL and redline treatments are available in the Pro-Trac Street Pro III line for several front and rear sizes.

That gives the CL63 AMG owner a real appearance choice without changing the basic radial sizing format. Blackwall keeps a more understated look, while raised white letter or redline sidewalls create a more custom visual statement. The important step is to choose the sidewall treatment only after confirming the correct front or rear size and the matching rim diameter.

The 2013 Mercedes-Benz CL63 AMG tire sizes are available from BFGoodrich, Nitto, and Pro-Trac. Depending on the exact size, choices include BFGoodrich g-Force series, Nitto NT555 G2, BFGoodrich g-Force Phenom T/A, and Pro-Trac Street Pro III options.

Brand alone should not make the decision. It is more useful to compare how each brand's offering lines up with the correct size, wheel-width range, sidewall style, and the kind of look you want on the car. Some sizes have broader brand coverage than others, so the final comparison may come down to tire series and appearance once fitment is confirmed.

A period-style approach for a 2013 Mercedes-Benz CL63 AMG usually starts by keeping the correct staggered radial size set for the wheel package already on the car. That means using either the 19-inch front-and-rear pair or the 20-inch front-and-rear pair, then selecting a tire series and sidewall treatment that suits the car's appearance goals.

Because this is a modern AMG coupe rather than an earlier whitewall-era collector car, the visual decision is more about presentation than strict historical restoration. Blackwall tires preserve a restrained, contemporary look, while RWL or redline can push the car toward a more personalized style. Buyers pursuing exact originality should compare against vehicle-specific historical references before settling on appearance details.

On a 2013 Mercedes-Benz CL63 AMG, construction is straightforward because the primary fitments are radial tires in all four applicable sizes. That keeps the visual character closer to the car's original era, with the main appearance differences coming from sidewall treatment and tire series rather than a choice between bias-ply and radial construction.

The larger visual decision is whether the car should wear a subtle blackwall look or something more expressive such as RWL or redline. Tire profile also changes slightly between the 19-inch and 20-inch setups, so wheel package affects the stance as much as sidewall style does. Appearance choices work best when they follow the correct front and rear sizing layout.

Yes. Wheel changes, altered offsets, suspension modifications, and body or brake clearance differences can all affect tire fitment on a 2013 Mercedes-Benz CL63 AMG. That matters even when the replacement tire is one of the correct primary sizes, because this car already uses a staggered setup and has separate front and rear fitment requirements.

A modified CL63 AMG should be checked for actual wheel diameter, width, and clearance at full steering lock and suspension travel before settling on a tire. Lowering the car or switching to aftermarket wheels can change how much room is available around the fenders and inner suspension points. Measuring the existing setup is safer than relying on assumptions.

Before road use, inspect wheel condition, verify that the correct front and rear sizes were installed, and confirm that each tire is seated properly on the intended rim diameter. Tire pressure, valve stems, tread condition, and any visible cuts, bulges, or shipping damage should also be checked before putting miles on the car.

It is also smart to make a quick clearance inspection with the wheels turned and the suspension loaded normally, especially if the CL63 AMG has non-stock wheels. A short, careful test drive can reveal vibration, rubbing, or pull that deserves attention. Catching those issues early helps protect both the tires and the car's suspension and steering components.

Tires on a 2013 Mercedes-Benz CL63 AMG should be maintained with regular pressure checks, visual inspections, and close attention to wear across all four positions. Because the car uses a staggered setup, front and rear tires are not the same size, so maintenance should focus on each axle's condition rather than treating the set as interchangeable.

Low-use performance cars still need periodic inspection for age-related cracking, flat spotting, air loss, or damage from long storage. Keep the tires away from prolonged sunlight, heat, moisture, and ozone sources when possible, and inspect them before longer drives. Any unusual wear pattern should prompt a check of alignment, suspension condition, and wheel setup.
