The 2007 Mercedes-Benz SL55 AMG sits in the era when AMG roadsters blended grand touring comfort with supercharged V8 performance and serious autobahn-style capability. Its retractable-hardtop SL platform gave the car a dual personality, equally at home cruising or covering ground at speed. Tire fitment is staggered, with different front and rear sizes, and the Performance Package changes both size and rim diameter from the standard setup. Available choices stay firmly in modern radial territory, with blackwall performance tires from BFGoodrich and Nitto across several series. For an SL55 AMG owner, the real task is matching the exact wheel package first, then choosing the tire character that best suits the car’s use and presentation.
Which Tire Size Is Right for The 2007 Mercedes-Benz SL55 AMG
The 2007 Mercedes-Benz SL55 AMG uses four primary tire sizes because fitment changes by front or rear position and by whether the car has the standard setup or the Performance Package. The first step is identifying your exact wheel package and confirming whether the car is on 18-inch or 19-inch rims. Once that is settled, the decision becomes choosing the right radial tire within the correct staggered size pair.
In 255/40R18, the 255 identifies nominal section width in millimeters, 40 is the aspect ratio, R designates radial construction, and 18 is the rim diameter in inches. This is the front tire size for the standard 18-inch wheel setup on the 2007 Mercedes-Benz SL55 AMG, giving the car its correct front-side stagger relationship. Available choices center on BFGoodrich blackwall performance radials in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size is the right place to start when the car retains its standard front wheel package and you want to compare tire series within that fitment.
In 285/35R18, the 285 is the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 18 marks the rim diameter in inches. This size serves the rear position on the standard 18-inch SL55 AMG setup, complementing the narrower front tire in the factory-style staggered arrangement. The available product choice here is a blackwall Nitto NT555 G2, which keeps the fitment focused on a dedicated performance-oriented radial. This is the size to verify when the car has standard 18-inch rear wheels and you are confirming the correct rear half of the staggered combination.
In 255/35R19, the 255 gives the nominal section width in millimeters, 35 is the aspect ratio, R means radial construction, and 19 identifies the rim diameter in inches. This size is used at the front on SL55 AMG models equipped with the Performance Package, so it belongs to the 19-inch wheel setup rather than the standard 18-inch arrangement. BFGoodrich offers blackwall options in several g-Force series, including Comp 2 AS, Sport Comp 2, and Phenom T/A. This fitment matters when the car is running the Performance Package front wheels and you want to stay within the correct stagger and rim diameter.
In 285/30R19, the 285 denotes nominal section width in millimeters, 30 is the aspect ratio, R signifies radial construction, and 19 indicates rim diameter in inches. This is the rear tire size paired with the Performance Package front fitment, completing the SL55 AMG’s 19-inch staggered setup. Its shorter-profile rear format distinguishes it clearly from the 18-inch rear arrangement, so wheel diameter must be confirmed before replacement. This size should be evaluated as the correct rear fitment only for cars already using the 19-inch Performance Package wheel package, not as a general substitute across all 2007 SL55 AMG configurations.
Sub-model fitment on the 2007 Mercedes-Benz SL55 AMG is really a wheel-package question, because the front and rear sizes differ and the Performance Package moves the car from 18-inch to 19-inch rims. Checking the exact front or rear position and confirming the wheel package prevents mixing standard and Performance Package sizes.

2007 Mercedes-Benz SL55 AMG Base Front
The Base Front position uses the standard 18-inch front fitment, which is distinct from both the rear tire and the Performance Package front size. Tire selection here centers on choosing among the available blackwall BFGoodrich radial series while keeping the correct front-side stagger intact.
The Base Rear position uses the matching 18-inch rear size for the standard staggered setup, separate from the front fitment and separate from the 19-inch Performance Package rear tire. Selection is more focused here, so the main priority is confirming the standard rear wheel package before replacing the tire.
2007 Mercedes-Benz SL55 AMG w/Performance Pkg. Front
The Performance Package Front position moves to a 19-inch front tire size, making it different from the standard SL55 AMG setup even though it remains a staggered radial arrangement. Tire choice is then about comparing the available BFGoodrich blackwall performance series within the correct 19-inch front fitment.
The Performance Package Rear position uses its own 19-inch rear size, paired specifically with the Performance Package front fitment rather than the standard 18-inch setup. The key step is confirming that the car is on the 19-inch rear wheel package so the stagger, profile, and rim diameter stay consistent.
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.

SL55 AMG tire questions usually come down to staggered sizing, 18-inch versus 19-inch wheel packages, and choosing the right radial tire for the front or rear position. The FAQs below focus on fitment, product selection, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2007 Mercedes-Benz SL55 AMG?
The 2007 Mercedes-Benz SL55 AMG uses a staggered radial setup, so front and rear tires are different. Standard-wheel cars use 255/40R18 in front and 285/35R18 in the rear, while SL55 AMG models with the Performance Package use 255/35R19 in front and 285/30R19 in the rear.
That means there is not one universal tire size for every 2007 SL55 AMG. The first step is confirming whether the car has the standard 18-inch setup or the 19-inch Performance Package wheels, then matching the correct front and rear sizes rather than replacing all four tires by width alone.
What size rim does a 2007 Mercedes-Benz SL55 AMG use?
A 2007 Mercedes-Benz SL55 AMG uses either 18-inch or 19-inch rims, depending on wheel package. The standard staggered setup uses 18-inch rims front and rear, while the Performance Package uses 19-inch rims front and rear with different low-profile tire sizes.
Rim diameter should be checked before looking at tread pattern or brand, because the tire sizes are tied directly to the wheel package. It is also important to confirm front and rear wheel widths and verify the actual wheels on the car if aftermarket replacements have been installed since new.
Why does the 2007 Mercedes-Benz SL55 AMG have more than one tire size?
The SL55 AMG uses more than one tire size because it has a staggered setup, with a narrower front tire and a wider rear tire, and the Performance Package changes the wheel diameter as well. That creates four primary fitments across the model: two for the standard setup and two for the Performance Package.
This matters because a front size is not meant to be treated as a rear size, and an 18-inch fitment should not be confused with a 19-inch fitment. Matching the exact wheel package keeps the tire profile and intended stagger relationship in line with the car’s current configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2007 Mercedes-Benz SL55 AMG?
Start with the exact wheel package and axle position, since the 2007 Mercedes-Benz SL55 AMG uses different front and rear sizes and may be equipped with either 18-inch or 19-inch rims. All primary fitments are radial, so the main selection points are the correct size, rim-width compatibility, tire series, and intended use.
A buyer comparing tires for this car should look at whether the setup is standard or Performance Package, then choose within the available options for that specific size. Load capacity, profile, and wheel-width range are worth reviewing alongside brand and series so the tire matches both the wheel and the car’s purpose.
What sidewall styles are available for 2007 Mercedes-Benz SL55 AMG tires?
The available tires for the 2007 Mercedes-Benz SL55 AMG use a blackwall sidewall style. That keeps the appearance modern and understated, which suits the SL55 AMG’s late-performance-roadster character and matches the type of performance radial commonly chosen for this sort of fitment.
Since sidewall treatment does not vary here, the more meaningful visual and functional decisions come from tire series and wheel package rather than from whitewall or lettered-sidewall choices. Owners focused on presentation can concentrate on maintaining a matched front and rear set with the correct profile for the car’s wheels.
What brands offer tires for the 2007 Mercedes-Benz SL55 AMG?
BFGoodrich and Nitto offer tires for the 2007 Mercedes-Benz SL55 AMG fitments shown here. BFGoodrich covers the 255 front sizes in several g-Force series, while Nitto appears in the 285/35R18 rear fitment with the NT555 G2.
Brand choice should still follow size and position first, because the available brand mix changes by fitment. A practical comparison includes the exact tire series, approved rim-width range, load figure where stated, and whether the tire is intended for the front or rear of the staggered SL55 AMG setup.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Mercedes-Benz SL55 AMG?
A period-style approach for a 2007 Mercedes-Benz SL55 AMG starts with preserving the correct wheel package and staggered sizing rather than chasing a vintage-looking sidewall. That means keeping the proper 18-inch standard setup or 19-inch Performance Package setup, then selecting a blackwall radial that suits the car’s late-performance character.
For an owner who wants the car to look right, consistency matters more than novelty. A matched front and rear set in the correct sizes will usually do more for the overall presentation than mixing profiles or substituting sizes, and marque-specific references are worth consulting when originality details are especially important.
Does correct tire fitment matter for a 2007 Mercedes-Benz SL55 AMG restoration?
Correct tire fitment matters on a 2007 Mercedes-Benz SL55 AMG restoration because the car’s appearance is closely tied to its staggered stance and low-profile wheel package. Using the proper front and rear sizes on the correct 18-inch or 19-inch rims helps preserve the visual balance that defines the car.
Fitment also affects how complete and coherent the finished restoration feels. Even when the goal is road use rather than concours judging, mismatched diameters, incorrect profiles, or mixed wheel-package sizes can make the car look unsettled, so confirming wheel dimensions and tire sizes before purchase is time well spent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz SL55 AMG?
Yes, modifications can affect tire fitment on a 2007 Mercedes-Benz SL55 AMG. Aftermarket wheels, altered wheel widths, suspension changes, lowered ride height, or body modifications can all change the way a 255 or 285 section-width tire sits in the wheelwell and clears suspension or fender components.
A car that no longer has its original wheel package should be measured rather than matched by model name alone. Confirming wheel diameter, wheel width, and available clearance at both the front and rear is especially important on a staggered setup, where each axle already uses a different tire size.
What should I inspect before driving a 2007 Mercedes-Benz SL55 AMG on new tires?
Before driving a 2007 Mercedes-Benz SL55 AMG on new tires, inspect the wheels for correct diameter and condition, verify that the tires are mounted in the proper front and rear positions, and make sure inflation is set appropriately. It is also wise to look for any rubbing points around the fenders, liners, and suspension.
A short test drive should be followed by another visual check, especially on a car with staggered sizes and low-profile fitment. Uneven seating, air loss, or clearance contact is easier to correct early, and a quick recheck helps confirm that the selected tires suit the wheel package actually on the car.
What should I check before a longer drive in a 2007 Mercedes-Benz SL55 AMG?
Before a longer drive, check tread and sidewall condition, confirm stable tire pressure, and inspect for cracking, bulges, cuts, or signs of prior curb damage. On a 2007 Mercedes-Benz SL55 AMG, it is also smart to confirm that the correct staggered front and rear sizes are in place for the car’s wheel package.
Collector and low-use performance cars can sit for long periods, so age and condition matter as much as tread depth. A longer drive is a good reason to look closely at the tires, verify that no slow air loss is present, and make sure the suspension and alignment are not creating uneven wear.
