The 2013 Mercedes-Benz SL63 AMG blends grand-touring luxury with modern AMG performance, making tire selection more than a routine replacement decision. This generation of SL balances high-speed composure, sharp response, and the visual presence expected from a top-tier roadster. Fitment centers on staggered radial sizes, with 255/35R19 used at the front and either 285/30R19 or 285/30R20 at the rear depending on wheel setup. That means the real choice is not only size, but also confirming rear rim diameter and comparing available series and sidewall treatments. For owners focused on road use, appearance, or preserving the car's intended stance, getting the exact front-to-rear combination right matters.
Which Tire Size Is Right for The 2013 Mercedes-Benz SL63 AMG
The 2013 Mercedes-Benz SL63 AMG uses three primary tire sizes, and the correct choice depends on position and rear wheel diameter. The front uses a 19-inch radial, while the rear may use either a 19-inch or 20-inch radial setup. Before selecting tires, confirm whether the car has the 19-inch rear wheel or the 20-inch rear wheel, then match the staggered front and rear sizes accordingly.
255/35R19 is a modern metric radial size in which 255 represents nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2013 Mercedes-Benz SL63 AMG, this size serves as the front fitment and supports the car's staggered performance setup. Available choices in this size come from BFGoodrich across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, all in Blackwall form. The key decision here is choosing a front tire that matches the car's intended use while staying compatible with the existing 19-inch wheel width.
285/30R19 is a modern metric radial size with a 285-millimeter nominal section width, a 30-series profile, radial construction, and a 19-inch rim diameter. For the 2013 Mercedes-Benz SL63 AMG, this size applies at the rear on a 19-inch rear-wheel configuration and should be paired with the correct 255/35R19 front size. Its role is specific to the rear of the car, so it is important not to confuse it with the 20-inch rear alternative. Choosing this size starts with confirming that the car still carries the proper 19-inch rear wheels rather than an alternate rear setup.
285/30R20 follows the same modern metric radial format, with 285 indicating nominal width in millimeters, 30 as the aspect ratio, R for radial construction, and 20 for the rim diameter in inches. On the 2013 Mercedes-Benz SL63 AMG, this is the alternate rear fitment used with a 20-inch rear wheel, so wheel diameter confirmation is essential before ordering. Available options include Nitto and Pro-Trac, with Blackwall, raised white letter, and Redline sidewall treatments represented in the product mix. This size is the one to evaluate when the car's rear-wheel setup emphasizes the larger 20-inch rear presentation.
Fitment on the 2013 Mercedes-Benz SL63 AMG is straightforward in layout but still requires attention to front and rear position. The front uses one size, while the rear can use two different sizes depending on rear wheel diameter, so identifying the exact wheel setup matters before selecting tires.

2013 Mercedes-Benz SL63 AMG Base Front
The Base Front position uses a 255/35R19 radial tire on a 19-inch wheel. Tire selection here is mainly about matching the correct front size and comparing the available BFGoodrich performance-oriented series within that fitment.
The Base Rear position uses either 285/30R19 or 285/30R20 radial tires, depending on which rear wheel diameter is on the car. That makes rear wheel confirmation the first step, followed by choosing the appropriate sidewall style and tire series for the intended look and road use.
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 2013 Mercedes-Benz SL63 AMG?
The 2013 Mercedes-Benz SL63 AMG uses a staggered radial tire setup. The front size is 255/35R19, while the rear uses either 285/30R19 or 285/30R20 depending on the rear wheel configuration on the car.
That means tire selection starts with position as well as size. The front is fixed at 19 inches, but the rear requires confirming whether the car has a 19-inch or 20-inch wheel before ordering. Matching the correct front-to-rear combination is important for maintaining the intended stance and avoiding a size mismatch across the staggered setup.
What size rim does a 2013 Mercedes-Benz SL63 AMG use?
The 2013 Mercedes-Benz SL63 AMG uses a 19-inch front rim with its 255/35R19 front tire. At the rear, the car uses either a 19-inch rim with 285/30R19 tires or a 20-inch rim with 285/30R20 tires.
Rear rim diameter is the key item to verify before replacing tires. A 285/30R19 and a 285/30R20 are both rear fitments for this model, but they are not the same wheel diameter. Checking the wheel itself is the safest first step, especially if the car has had wheel changes or if its current setup differs from another SL63 AMG you may be comparing it to.
Why does the 2013 Mercedes-Benz SL63 AMG have more than one tire size?
The 2013 Mercedes-Benz SL63 AMG has more than one tire size because it uses a staggered fitment. The front and rear tires are different sizes, and the rear also appears in both 19-inch and 20-inch versions depending on the wheel arrangement.
That combination is common on performance-oriented cars where front and rear tire duties are not the same. The practical result is that a buyer should identify both axle position and rear wheel diameter before choosing tires. It also helps to inspect the existing wheel and tire markings on the car rather than relying only on a general model description.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 front tire for a 2013 Mercedes-Benz SL63 AMG?
Start with the correct front size, 255/35R19, and keep the tire radial to match the car's original construction type. In this size, the available choices come from BFGoodrich and vary by series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A.
Beyond size, compare the stated rim-width compatibility and the type of use the tire lineup suggests. All of the listed front options are Blackwall, so the main differences come from series selection and related specifications rather than sidewall styling. It also makes sense to choose a front tire that complements the rear setup already on the car.
What sidewall styles are available for 2013 Mercedes-Benz SL63 AMG tires?
Sidewall style depends on the tire size you are shopping. The 255/35R19 front options appear in Blackwall form, while the 285/30R20 rear options include Blackwall, RWL, and Redline treatments.
That makes sidewall choice part of the visual decision, especially on the rear where the tire is more noticeable. A Blackwall presentation keeps the look understated, while raised white letter or Redline options create a more customized appearance. Style should still come after confirming the exact rear rim diameter, since a sidewall treatment in 20-inch form does not make it a substitute for the 19-inch rear fitment.
What brands offer tires for the 2013 Mercedes-Benz SL63 AMG?
Tires for the 2013 Mercedes-Benz SL63 AMG are available from BFGoodrich, Nitto, and Pro-Trac in the sizes represented here. BFGoodrich appears in the 255/35R19 front size, while Nitto and Pro-Trac appear in the 285/30R20 rear size.
Brand selection should be considered alongside the exact size and wheel position, not as a standalone decision. A front tire and a rear tire on this car serve different fitment roles, so the first step is matching the correct size to the correct axle. Once that is settled, comparing series names, sidewall style, and any stated load or wheel-width details becomes more useful.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Mercedes-Benz SL63 AMG?
A period-style approach for a 2013 Mercedes-Benz SL63 AMG starts with preserving the proper staggered sizing and the correct rear wheel diameter. That means using 255/35R19 at the front and then confirming whether the rear calls for 285/30R19 or 285/30R20.
Once the sizing is correct, appearance comes from the sidewall treatment and overall presentation rather than from changing construction type, since the fitment is already radial. A restrained Blackwall look suits a clean contemporary presentation, while some rear 20-inch options add more visual character. Owners pursuing exact delivery-day appearance should compare against marque references and the car's original wheel setup.
How does tire construction affect the appearance of a restored 2013 Mercedes-Benz SL63 AMG?
On a 2013 Mercedes-Benz SL63 AMG, construction is less of an appearance divide than it is on older collector cars because the fitment is radial throughout. The visual differences here are more likely to come from wheel diameter, tire profile, and sidewall treatment than from switching between bias-ply and radial construction.
That makes correct sizing especially important to the car's finished look. A 19-inch rear and a 20-inch rear do not present the same way, even though both are valid rear fitments for this model. Keeping the front and rear sizes properly matched will do more for the car's stance and proportions than chasing an appearance cue that does not belong to this generation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Mercedes-Benz SL63 AMG?
Yes, modifications can affect tire fitment on a 2013 Mercedes-Benz SL63 AMG. Aftermarket wheels, altered offsets, suspension changes, ride-height adjustments, or body modifications can all change how a 255/35R19 front or 285/30 rear tire sits in the wheel opening.
A car with changes from stock should be checked carefully before replacing tires by size alone. Wheel diameter is only one part of the picture, especially at the rear where both 19-inch and 20-inch fitments exist. It is smart to verify wheel width, clearance at full steering lock, and room around the fender and suspension before finalizing a replacement.
What should I inspect before driving a 2013 Mercedes-Benz SL63 AMG on new tires?
Before driving a 2013 Mercedes-Benz SL63 AMG on new tires, inspect the wheel condition, confirm that the front and rear sizes are matched correctly, and check inflation pressure once the tires are mounted. It also helps to look over valve stems, lug hardware, and the visible condition of the suspension and brake components.
A short initial road test is a sensible next step. Pay attention to vibration, rubbing, unusual noise, or any sign that the rear tires do not match the wheel diameter on the car. Rechecking pressure after the first drive and confirming that there is no contact under steering or suspension movement adds a useful layer of confidence before regular use.
How often should tires on a 2013 Mercedes-Benz SL63 AMG be inspected?
Tires on a 2013 Mercedes-Benz SL63 AMG should be inspected regularly, especially if the car is driven seasonally or spends long periods parked. Pressure, tread condition, uneven wear, cuts, bulges, and sidewall aging are all worth checking as part of routine care.
Performance-oriented, low-profile tires can reveal alignment or suspension issues quickly, so visual inspection should become a habit rather than an occasional task. It is also wise to inspect before a longer drive, after storage, or any time the car feels different on the road. Staying ahead of small issues helps protect both the wheels and the overall driving character of the car.
