The 2013 Mercedes-Benz SL550 belongs to a generation of SL roadsters that blended grand touring comfort with modern performance, using wide staggered tires to support the car’s balance, grip, and visual stance. For this exact model, tire selection starts with confirming whether the car is on the 18-inch or 19-inch wheel setup, because the front and rear sizes differ as part of the staggered arrangement. All primary fitments are radial, with 255-section front tires and 285-section rear tires. Available choices focus less on vintage-style appearance and more on matching the correct wheel package, tire series, and road-use priorities before replacing a set.
Which Tire Size Is Right for The 2013 Mercedes-Benz SL550
The 2013 Mercedes-Benz SL550 uses four primary tire sizes because it has a staggered front-and-rear setup offered in both 18-inch and 19-inch wheel configurations. The first step is confirming wheel diameter, then matching the correct front and rear pair, since the front sizes differ from the rear sizes and all of them are radial fitments.
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 rim diameter in inches. On the 2013 Mercedes-Benz SL550, this size serves the front position on the 19-inch setup and keeps the staggered relationship with the wider rear tire. Available choices in this size come from BFGoodrich in Blackwall form across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size should be matched to the correct rear companion and the actual wheel package on the car.
255/40R18 is a metric radial size with a 255-millimeter nominal section width, a 40-series profile, and an 18-inch rim diameter. On the 2013 Mercedes-Benz SL550, it is the front tire size used with the 18-inch wheel setup, again as part of a staggered arrangement rather than a square setup. BFGoodrich offers this size in Blackwall construction across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. It is a useful starting point for owners confirming an 18-inch front wheel before selecting the matching rear size and comparing tire series characteristics.
285/30R19 is a metric radial size where 285 represents nominal section width in millimeters, 30 indicates a lower-profile sidewall, and 19 identifies the rim diameter. For the 2013 Mercedes-Benz SL550, this size belongs at the rear on the 19-inch wheel package and provides the wider rear fitment that completes the factory-style staggered layout. Its role is not interchangeable with the front tire size, even though both are mounted on 19-inch wheels in that package. Choosing this size starts with verifying that the car has the 19-inch rear wheel setup and that the replacement tire suits the wheel width and rear clearance requirements.
285/35R18 is a metric radial size with a 285-millimeter nominal section width, a 35-series profile, and an 18-inch rim diameter. On the 2013 Mercedes-Benz SL550, it is the rear tire size paired with the 18-inch front fitment, maintaining the car’s staggered front-to-rear setup. The available product choice in this size is a Blackwall Nitto NT555 G2, giving the buyer a focused rear replacement option rather than a broad mix of brands and sidewall styles. This size matters most when confirming the 18-inch rear wheel and preserving the intended front-and-rear tire relationship.
Fitment on the 2013 Mercedes-Benz SL550 is straightforward once the tire position is identified, because the covered sub-models separate front and rear sizing rather than trim-level variations. Checking whether the tire is for the front axle or rear axle matters first, and wheel diameter still has to match the 18-inch or 19-inch setup on the car.

These FAQs focus on the exact tire sizes used on the 2013 Mercedes-Benz SL550, how the staggered front-and-rear fitment works, and what to check when choosing replacement tires for either the 18-inch or 19-inch wheel setup.
Tire Size & Fitment
What tire size fits a 2013 Mercedes-Benz SL550?
The 2013 Mercedes-Benz SL550 uses a staggered radial tire setup with different front and rear sizes. Front fitments are 255/40R18 or 255/35R19, while rear fitments are 285/35R18 or 285/30R19, depending on which wheel package is on the car.
That means the right answer is not one single size for every SL550. The first check is whether the car has 18-inch or 19-inch wheels, then the replacement tire has to match the correct axle position. Front and rear sizes should not be mixed casually, and a previous owner may have changed wheels, so reading the current tire sidewall and confirming wheel diameter is the safest starting point.
What size rim does a 2013 Mercedes-Benz SL550 use?
A 2013 Mercedes-Benz SL550 uses either 18-inch or 19-inch rims, depending on the wheel setup installed on the car. The 18-inch package uses 255/40R18 front and 285/35R18 rear tires, while the 19-inch package uses 255/35R19 front and 285/30R19 rear tires.
Rim diameter has to be confirmed before choosing replacement tires because each tire size is built around a specific wheel diameter. The front and rear sizes also remain staggered, so confirming only one tire is not enough. Checking the markings on both the wheel and tire sidewall helps avoid ordering an 18-inch tire for a 19-inch wheel, or selecting a front size when the car needs a rear.
Why does the 2013 Mercedes-Benz SL550 have more than one tire size?
The 2013 Mercedes-Benz SL550 has more than one tire size because it uses a staggered setup, with narrower tires in front and wider tires in back, and it was fitted with either an 18-inch or 19-inch wheel package. That creates four primary sizes across the full vehicle fitment.
In practical terms, the tire choice depends on two things: axle position and wheel diameter. A front tire size is not a rear replacement, and an 18-inch size is not a substitute for a 19-inch wheel. Owners should confirm whether they are replacing a front or rear tire, then verify the wheel setup currently on the car, especially if it has had wheel, suspension, or appearance modifications.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Mercedes-Benz SL550?
Start with the exact size, wheel diameter, and axle position. The 2013 Mercedes-Benz SL550 uses staggered radial fitments, so the correct choice depends on whether the tire is for the front or rear and whether the car is on the 18-inch or 19-inch setup.
After that, compare the tire series and the wheel-width compatibility of the product you are considering. Front sizes have BFGoodrich choices in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, while the 18-inch rear fitment includes the Nitto NT555 G2. Matching the intended use, wheel dimensions, and full front-to-rear set relationship matters more than choosing by size name alone.
What sidewall styles are available for 2013 Mercedes-Benz SL550 tires?
The available tires for the 2013 Mercedes-Benz SL550 fitments shown here use a Blackwall sidewall style. That applies across the BFGoodrich front-size options and the Nitto rear 18-inch option, giving the car a clean modern presentation rather than a decorative collector-style sidewall treatment.
Since sidewall appearance is consistent, most of the real selection happens in tire series, wheel compatibility, and matching the correct front or rear size. For owners replacing only one axle, keeping sidewall style consistent helps preserve the car’s overall appearance. It is also worth checking that the chosen tire maintains the proper staggered setup and suits the wheel width on the car before installation.
What brands offer tires for the 2013 Mercedes-Benz SL550?
BFGoodrich and Nitto offer tires in the fitments covered for the 2013 Mercedes-Benz SL550. BFGoodrich supplies the available front-size options in both 18-inch and 19-inch fitments, while Nitto appears in the available 285/35R18 rear size.
Brand alone should not drive the decision, because each size and axle position has its own role in the SL550’s staggered layout. A better approach is to confirm the exact size first, then compare the available series within that fitment. That keeps the selection focused on wheel diameter, axle position, and tire characteristics instead of assuming every brand option appears in every size used on the car.
Restoration & Appearance
Does correct tire fitment matter for a 2013 Mercedes-Benz SL550 restoration?
Yes, correct tire fitment matters on a 2013 Mercedes-Benz SL550 because the car uses a staggered modern radial setup tied to specific 18-inch or 19-inch wheel packages. Using the wrong front-to-rear pairing can change the car’s stance and compromise the intended relationship between the wheel and tire proportions.
For a restoration-oriented project, preserving the proper size family is usually more important than chasing decorative sidewall details, since the available tires here are Blackwall performance radials. Owners seeking exact appearance accuracy should confirm the wheel package actually installed on the car and compare it against model-specific references, especially if the SL550 has had aftermarket wheels fitted at some point in its life.
How does tire construction affect the appearance of a restored 2013 Mercedes-Benz SL550?
On a 2013 Mercedes-Benz SL550, tire construction is straightforward because the primary fitments are radial. That suits the car’s modern design language, low-profile proportions, and wide staggered stance, so the right radial size contributes more to the restored appearance than switching to a different construction type would.
Appearance is influenced most by getting the correct front and rear size pairing for the wheel package on the car. A 19-inch setup presents differently than an 18-inch setup, even though both belong to this model. Keeping the proper axle-specific sizes, matching sidewall style across the set, and avoiding mismatched wheel diameters will usually do more for the finished look than changing brands alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Mercedes-Benz SL550?
Yes, modifications can affect tire fitment on a 2013 Mercedes-Benz SL550. Wheel changes, altered offsets, suspension lowering, replacement springs, or bodywork changes can all influence how a 255-section front or 285-section rear tire sits within the wheel opening and how much clearance remains during steering or suspension travel.
That is especially important on a car with low-profile staggered tires. Even when the sidewall size matches one of the original fitments, wheel width and wheel position can change the result. Any SL550 with aftermarket wheels should be checked carefully for inner clearance, fender clearance, and full-lock steering clearance before assuming a replacement tire in the correct nominal size will behave the same as the previous setup.
What should I inspect before driving a 2013 Mercedes-Benz SL550 on new tires?
Before driving a 2013 Mercedes-Benz SL550 on new tires, inspect wheel condition, verify that the front and rear sizes are mounted in the correct positions, and confirm inflation is appropriate for the tires installed. It is also smart to look for uneven wear patterns that could point to alignment or suspension issues.
A short recheck after initial driving is worthwhile because staggered low-profile tires can reveal vibration, rubbing, or clearance issues quickly if the setup is not quite right. Owners should also make sure lug hardware is properly secured and watch for any air loss during the first days of use. A clean inspection before road use helps protect both the tires and the wheels from avoidable problems.
How often should tires on a 2013 Mercedes-Benz SL550 be inspected?
Tires on a 2013 Mercedes-Benz SL550 should be inspected regularly, not just when tread looks low. A visual check for cuts, bulges, cracking, uneven wear, and pressure loss is a good habit before longer drives, and it is especially useful on performance-oriented low-profile tires that can be more sensitive to impact damage.
Cars that see occasional use still need routine inspection because aging and underinflation can develop even when mileage stays low. Looking at both front and rear tires matters since the SL550 uses different sizes at each axle and they may not wear the same way. Frequent checks also help catch alignment, balance, or suspension issues before they shorten the life of a new set.
