The 2017 Mercedes-Benz SL63 AMG blends long-hood SL roadster luxury with serious AMG performance, making tire fitment more than a cosmetic detail. This is a modern high-powered grand touring car with a staggered radial setup, using 255/35R19 up front and either 285/30R19 or 285/30R20 at the rear depending on the wheel configuration. That means the first step is confirming whether the car is on a 19-inch or 20-inch rear wheel, then narrowing the choice by tire series and sidewall style. For an owner balancing road manners, appearance, and proper fitment, the right decision starts with the exact front-and-rear combination on the car.
Which Tire Size Is Right for The 2017 Mercedes-Benz SL63 AMG
Three tire sizes apply to the 2017 Mercedes-Benz SL63 AMG, and the fitment is split by position and rear wheel diameter rather than by unrelated trim differences. The front uses one size, while the rear uses either a 19-inch or 20-inch fitment, so the first step is confirming whether the car has a 19-inch or 20-inch rear wheel before selecting a tire.
255/35R19 is a modern metric radial size in which 255 identifies nominal section width in millimeters, 35 is the aspect ratio, R designates radial construction, and 19 is the wheel diameter in inches. On the 2017 Mercedes-Benz SL63 AMG, this size serves the front position and reflects the lower-profile, performance-oriented setup expected on a staggered application. Available choices in this size come from BFGoodrich in several g-Force series, all with Blackwall styling. This is the size to match when replacing the SL63 AMG's front tires and maintaining the intended front fitment.
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. On the 2017 Mercedes-Benz SL63 AMG, this is one of the rear tire sizes, so it belongs only on cars using the 19-inch rear wheel setup. Its role is tied to the staggered rear fitment, not the front axle. Before choosing this size, confirm that the car actually carries a 19-inch rear wheel, since rear fitment on this model can also step up to a 20-inch diameter.
285/30R20 follows the same modern metric radial sizing format, with 285 as the nominal section width in millimeters, 30 as the aspect ratio, R for radial construction, and 20 for wheel diameter. On the 2017 Mercedes-Benz SL63 AMG, this size is used at the rear on cars equipped with the 20-inch rear wheel configuration. Available products in this size include Nitto and Pro-Trac, with Blackwall, raised white letter, and Redline sidewall treatments. This rear size is the one to evaluate when the car carries 20-inch rear wheels and appearance choice matters alongside fitment.
Fitment on the 2017 Mercedes-Benz SL63 AMG is straightforward in name but not identical at all four corners. The key distinction is front versus rear, with the rear tire size changing according to rear wheel diameter, so confirming axle position and wheel size matters before choosing a replacement.

2017 Mercedes-Benz SL63 AMG Base Front
The Base Front position uses a single radial front fitment, which keeps front-tire selection focused on matching the correct size and choosing among the available tire series in that application. That makes the main decision less about fitment variation and more about selecting the product characteristics that suit the car's use.
The Base Rear position uses two possible radial sizes, with the correct choice determined by whether the car has a 19-inch or 20-inch rear wheel. Rear-tire selection starts with wheel confirmation, then moves to comparing the available tire options and sidewall treatments within 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.

Owners of a 2017 Mercedes-Benz SL63 AMG usually need to confirm the staggered front-and-rear sizing first, then sort through rear wheel diameter, product selection, and appearance choices. These FAQs focus on exact size fitment, radial-only construction, sidewall options, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2017 Mercedes-Benz SL63 AMG?
The 2017 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 the correct choice is not just about year, make, and model. The front fitment is fixed, but the rear requires a wheel-diameter check before ordering replacement tires. Matching the exact front-and-rear combination already on the car is the safest way to keep sizing consistent, especially if the car may have had wheel changes at some point.
What size rim does a 2017 Mercedes-Benz SL63 AMG use?
The 2017 Mercedes-Benz SL63 AMG uses 19-inch front rims with the 255/35R19 front tire. At the rear, the car may use either a 19-inch rim with 285/30R19 tires or a 20-inch rim with 285/30R20 tires.
Front rim diameter is straightforward, but the rear must be verified on the car before selecting tires. Check the wheel itself or the existing rear tire size rather than assuming all four corners match. Because this is a staggered application, using the wrong rear diameter can stop the tire from mounting correctly and complicate overall fitment.
Why does the 2017 Mercedes-Benz SL63 AMG have more than one tire size?
The 2017 Mercedes-Benz SL63 AMG has more than one tire size because it uses a staggered setup with a dedicated front size and alternate rear sizes. The front is 255/35R19, while the rear is either 285/30R19 or 285/30R20 depending on the wheel arrangement.
This kind of fitment places the first decision on wheel position and rear wheel diameter, not just the vehicle nameplate. A front tire should be chosen from the front size, and a rear tire should be chosen only after confirming whether the car carries a 19-inch or 20-inch rear wheel. That check becomes especially important on vehicles with aftermarket wheel packages.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2017 Mercedes-Benz SL63 AMG?
For the 255/35R19 front fitment, start with the exact size, radial construction, and 19-inch wheel diameter. Then compare the available BFGoodrich choices by tire series, stated rim-width range, load specification where shown, and the overall character of each g-Force offering.
Selection becomes easier once the fitment is confirmed. A buyer looking for a straightforward Blackwall presentation can focus on appearance consistency, while another owner may compare series details and construction labeling within the same size. Since this tire serves the front position, it also helps to replace it in a way that keeps the front axle properly matched side to side.
What sidewall styles are available for 2017 Mercedes-Benz SL63 AMG tires?
Sidewall styling varies by size on the 2017 Mercedes-Benz SL63 AMG. Blackwall options are available in the front 255/35R19 size, while the 285/30R20 rear size is available in Blackwall, raised white letter, and Redline versions depending on the tire line.
That gives the rear 20-inch fitment more visual variety than the front. If appearance matters, make sure the sidewall treatment suits the look of the car without overlooking the basic fitment requirements first. Tire style can change the visual tone of the SL63 AMG considerably, but wheel diameter and the correct staggered sizing still need to lead the decision.
What brands offer tires for the 2017 Mercedes-Benz SL63 AMG?
Available tires for the 2017 Mercedes-Benz SL63 AMG come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in the 255/35R19 front fitment, while Nitto and Pro-Trac appear in the 285/30R20 rear fitment.
Brand choice should be considered alongside the actual tire size, axle position, and wheel diameter already on the car. A front tire brand cannot simply be moved into a rear fitment if the size is different, and the 19-inch and 20-inch rear setups should not be mixed casually. Start with the correct location on the car, then compare the available brand and series options within that exact size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz SL63 AMG?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz SL63 AMG. Aftermarket wheels, suspension changes, altered ride height, or non-original front-to-rear wheel combinations can all change which tire size is appropriate and whether the existing staggered setup has been preserved.
Checking the actual wheel diameter and the tire size currently mounted is the best starting point before replacing anything. Clearance at the fender, inner wheelhouse, and steering range also matters on a low-profile performance application. Even when the vehicle name is correct, a modified wheel and suspension package can change what fits safely and what maintains proper overall balance.
What should I inspect before driving a 2017 Mercedes-Benz SL63 AMG on new tires?
Before driving a 2017 Mercedes-Benz SL63 AMG on new tires, inspect mounting direction, inflation pressure, valve condition, wheel condition, and basic clearance at both front and rear. It also helps to confirm that the correct staggered sizes are mounted in the correct positions and that both rear tires match each other.
A short visual and road check can prevent larger issues later. Look for sidewall contact, uneven seating on the rim, vibration, or any sign that the car has a mixed rear-wheel setup. On a performance roadster with low-profile radials, proper pressure and a clean, damage-free wheel are just as important as choosing the right tire size.
How often should tires on a 2017 Mercedes-Benz SL63 AMG be inspected?
Tires on a 2017 Mercedes-Benz SL63 AMG should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Check tread wear, air pressure, cuts, bulges, cracking, and any uneven wear pattern that could point to alignment, wheel, or suspension issues.
Collector and seasonal-use cars can age their tires without adding many miles, so appearance alone is not enough. A routine inspection before drives and at regular intervals during storage helps catch slow air loss or sidewall deterioration early. It is also a useful time to verify that the front and rear tires still match the staggered setup intended for the car.
