The 2013 Mercedes-Benz SL65 AMG sits at the high-output end of the R231 SL range, blending grand touring comfort with the kind of torque and top-speed capability that puts real demands on tire choice. On this car, fitment is not a single-size decision, because the front uses 255/35R19 while the rear can use either 285/30R19 or 285/30R20 depending on the wheel setup. That makes this a radial-only fitment question centered on axle position and rim diameter. Available choices also bring in different brands, tire series, and sidewall looks. Before selecting a set, confirm whether the car is running the 19-inch or 20-inch rear wheel arrangement and whether appearance or performance presentation matters most.
Which Tire Size Is Right for The 2013 Mercedes-Benz SL65 AMG
Three tire sizes apply to the 2013 Mercedes-Benz SL65 AMG, and the correct choice depends first on axle position and rear wheel diameter. The front uses one 19-inch radial size, while the rear can be matched to either a 19-inch or 20-inch radial setup. Before comparing products, confirm whether you are replacing the front tires or the rear tires, and verify which rear wheel diameter is currently on the car.
255/35R19 is a metric radial size in which 255 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2013 Mercedes-Benz SL65 AMG, this size serves the front fitment and reflects the modern low-profile performance character of the car. Available options in this size come from BFGoodrich in blackwall form across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This is the size to evaluate when replacing front tires and comparing series, load specification, and intended road use.
285/30R19 is a metric radial size with a 285-millimeter nominal section width, a 30-series profile, and a 19-inch rim diameter. On the 2013 Mercedes-Benz SL65 AMG, it belongs to the rear fitment when the car is equipped with the 19-inch rear wheel arrangement. Its low-profile radial construction suits the staggered front-to-rear layout typical of modern high-performance grand touring cars. This is the rear size to verify if the car runs 19-inch wheels at both ends, because confusing it with the 20-inch rear option can lead to an obvious diameter mismatch.
285/30R20 is a metric radial size where 285 gives the nominal section width in millimeters, 30 is the aspect ratio, and 20 is the wheel diameter in inches. On the 2013 Mercedes-Benz SL65 AMG, this size is used at the rear on cars with the 20-inch rear wheel setup. Available products include blackwall, raised white letter, and redline presentations from Nitto and Pro-Trac, giving this rear size more visible appearance variety than the front. It is the right size to compare when the car already has 20-inch rear wheels and the goal is to balance look, construction details, and rear-wheel compatibility.
Fitment on the 2013 Mercedes-Benz SL65 AMG is straightforward once axle position is identified, but the rear does require extra attention because two rear sizes are used. Checking the exact front or rear application matters more here than trim level, especially when confirming 19-inch versus 20-inch rear wheels.

2013 Mercedes-Benz SL65 AMG Base Front
The Base Front position uses a 255/35R19 radial tire, making front replacement a focused size-and-series decision rather than a construction change. Tire selection here comes down to choosing among the available radial performance options and confirming the wheel remains the original 19-inch front setup.
The Base Rear position can use either a 285/30R19 radial or a 285/30R20 radial, so rear tire selection starts with wheel-diameter confirmation. Once the rear wheel size is verified, the remaining choice is between the available brand, series, and sidewall treatments offered in the correct rear size.
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 SL65 AMG?
The 2013 Mercedes-Benz SL65 AMG uses a staggered tire setup. The front size is 255/35R19, while the rear uses either 285/30R19 or 285/30R20 depending on the rear wheel arrangement. All of these are radial tire sizes, and they are not interchangeable across positions simply because they belong to the same vehicle.
The important step is to identify whether you are replacing the front or rear tires and then confirm the actual wheel diameter on the rear axle. Many fitment mistakes happen when a buyer assumes every SL65 AMG uses the same rear size, so measuring or checking the wheel before ordering is the safest approach.
What size rim does a 2013 Mercedes-Benz SL65 AMG use?
The 2013 Mercedes-Benz SL65 AMG uses 19-inch rims at the front with its 255/35R19 tire size. At the rear, the car may use either a 19-inch rim with 285/30R19 or a 20-inch rim with 285/30R20. That means this model uses more than one wheel diameter across the covered fitments.
Rim diameter is the first thing to verify before selecting a rear tire, because a 19-inch tire and a 20-inch tire cannot be mounted on the same wheel. It is also worth confirming that the car still has its intended wheel package, especially if wheels were changed at some point during previous ownership.
Why does the 2013 Mercedes-Benz SL65 AMG have more than one tire size?
The 2013 Mercedes-Benz SL65 AMG has more than one tire size because it uses a staggered fitment and also appears with two different rear wheel diameters. The front is 255/35R19, while the rear is wider and can be either 285/30R19 or 285/30R20. That combination supports the car's performance-oriented layout.
For the owner, this means tire selection starts with position and wheel confirmation rather than brand preference alone. Front and rear tires serve different roles, and the rear size must match the actual wheel on the car. A quick visual check of the sidewall marking or wheel diameter can prevent ordering the wrong rear tire.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2013 Mercedes-Benz SL65 AMG?
A 255/35R19 front tire for the 2013 Mercedes-Benz SL65 AMG should first match the correct wheel diameter and intended front-axle application. In this size, BFGoodrich options include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all in blackwall form. Some also include load details and rim-width guidance that help narrow the choice.
Selection usually comes down to how the car is driven and what specifications matter most on the front axle. Compare tire series, sidewall presentation, weight, and any stated load information, then make sure the wheel width falls within the tire's usable range. Staying focused on front-specific fitment keeps the choice much cleaner.
What sidewall styles are available for 2013 Mercedes-Benz SL65 AMG tires?
Sidewall style varies by size on the 2013 Mercedes-Benz SL65 AMG. The available 255/35R19 front options are blackwall tires, while the 285/30R20 rear options include blackwall, raised white letter, and redline treatments. Those sidewall differences affect appearance more than basic fitment, but they can noticeably change how the car presents from the side.
That makes sidewall choice especially relevant if the SL65 AMG has a custom visual direction or if the goal is a cleaner, more understated look. The key is to separate appearance from fitment: choose the correct size and wheel diameter first, then compare sidewall style within the products that match the rear or front position.
What brands offer tires for the 2013 Mercedes-Benz SL65 AMG?
Available tire brands for the 2013 Mercedes-Benz SL65 AMG include BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in the 255/35R19 front size, while Nitto and Pro-Trac appear in the 285/30R20 rear size. Brand choice here is tied closely to the exact tire size and axle position rather than to the model as a whole.
That means the best way to compare brands is to start with the size the car actually needs at that corner of the vehicle. Once the position and wheel diameter are confirmed, compare each brand's available series, sidewall treatment, and any useful specification details instead of assuming every brand is offered in every SL65 AMG fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Mercedes-Benz SL65 AMG?
A period-style tire choice for a 2013 Mercedes-Benz SL65 AMG starts with keeping the correct modern low-profile radial size at each axle position. The front uses 255/35R19, while the rear requires either 285/30R19 or 285/30R20 depending on the wheel setup. On a car from this era, preserving the intended staggered stance usually matters more than chasing a vintage-looking construction.
Appearance choice then becomes a matter of tire series and sidewall style within the proper size. A blackwall presentation tends to maintain a more understated modern luxury-performance look, while raised white letter or redline sidewalls on certain rear tires push the car toward a more personalized visual statement. Wheel diameter should still be confirmed before anything else.
How does tire construction affect the appearance of a restored 2013 Mercedes-Benz SL65 AMG?
On the 2013 Mercedes-Benz SL65 AMG, tire construction is straightforward because the applicable fitments are radial. That suits the car's original-era visual character, since its low-profile modern wheel-and-tire proportions depend on radial sizing rather than vintage bias-ply styling. In practical terms, the appearance difference comes more from sidewall profile and sidewall treatment than from construction type.
For an owner refreshing the car cosmetically, the visible choices are more about maintaining the correct front-to-rear stagger and selecting blackwall, raised white letter, or redline where available. A tire that matches the proper diameter and profile helps preserve the SL65 AMG's intended stance, while an incorrect rear size can make the car look visibly off even before it is driven.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Mercedes-Benz SL65 AMG?
Yes, modifications can affect tire fitment on a 2013 Mercedes-Benz SL65 AMG. Aftermarket wheels, altered offsets, suspension changes, lowering, or body modifications can all change the space available for a 255/35R19 front tire or either rear size. That matters even when the tire size itself looks correct on paper.
A modified car should be checked for wheel diameter, wheel width, inner clearance, and fender clearance before replacing tires. The rear axle deserves extra attention because both 19-inch and 20-inch fitments are used on this model. Looking at the existing tire size and wheel markings before purchase is a simple way to avoid an expensive mismatch.
What should I inspect before driving a 2013 Mercedes-Benz SL65 AMG on new tires?
Before driving a 2013 Mercedes-Benz SL65 AMG on new tires, inspect that each tire matches the intended axle position, that the wheel diameter is correct, and that the tires are seated and inflated properly. It is also smart to look over the wheels themselves for damage, confirm valve-stem condition, and make sure there is no rubbing at full steering lock or under suspension movement.
A quick post-installation check can prevent small issues from becoming costly ones. Recheck tire pressure after the first drives, pay attention to any vibration or pull, and verify that front and rear sizes have not been mixed incorrectly. On a staggered car with multiple rear fitments, that final confirmation is especially important.
How often should tires on a 2013 Mercedes-Benz SL65 AMG be inspected?
Tires on a 2013 Mercedes-Benz SL65 AMG should be inspected regularly, especially because this model uses low-profile performance sizes that can be more sensitive to impact damage and uneven wear. Check tread condition, sidewalls, and pressure on a routine basis, and look closely after pothole strikes or any curb contact. Regular inspection matters just as much on a lightly used collector car as on a frequently driven one.
Cars that spend long periods parked deserve extra attention because aging, air loss, and flat spotting can appear even when mileage stays low. A simple habit of checking pressure and visual condition before longer drives helps protect both ride quality and wheel health. Any cracking, bulging, or persistent pressure loss should be addressed before road use.
