The 2017 Mercedes-Benz SLC300 carries the compact roadster formula into Mercedes-Benz’s modern turbo era, blending open-top touring manners with a sharper, more contemporary chassis feel than earlier generations. Buyers looking at this exact model are usually balancing appearance, wheel setup, and the car’s staggered front-to-rear fitment rather than hunting for a single universal tire size. The SLC300 uses radial tires in either a 17-inch or 18-inch package, with narrower 225-section front sizes and wider 245-section rear sizes. Available choices include blackwall performance radials, with select 17-inch front options also offered in raised white letter or redline form. The key is confirming which wheel package is on the car before comparing series, sidewall style, and rim-width compatibility.
Which Tire Size Is Right for The 2017 Mercedes-Benz SLC300
The 2017 Mercedes-Benz SLC300 uses four primary tire sizes because it carries a staggered fitment and was offered with either 17-inch or 18-inch wheels. Front tires use a 225-section size and rear tires use a wider 245-section size, so the first step is confirming both your exact wheel diameter and whether you are selecting for the front or rear axle before comparing tire choices.
225/40R18 is a metric radial size in which 225 identifies the nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 18 is the rim diameter in inches. On the 2017 Mercedes-Benz SLC300, this size serves the front axle on the 18-inch setup and reflects the car’s lower-profile, modern roadster fitment. Available choices include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when the car has 18-inch front wheels and you want to compare performance-oriented radial options within the correct front fitment.
225/45R17 is a metric radial size with a 225-millimeter nominal section width, a 45-series profile, radial construction, and a 17-inch rim diameter. On the 2017 Mercedes-Benz SLC300, it is the front tire size for the 17-inch wheel package, so it should be treated as a front-axle fitment rather than a universal size for the whole car. Product choice is broader here, with BFGoodrich, Nitto, and Pro-Trac options as well as blackwall, raised white letter, and redline sidewall treatments. This size deserves extra attention if your SLC300 runs 17-inch wheels and you want the widest appearance and series selection on the front axle.
245/35R18 is a metric radial size where 245 is the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter. For the 2017 Mercedes-Benz SLC300, this is the rear tire size used with the 18-inch package, pairing a wider section width with a low-profile sidewall to match the car’s staggered setup. The available product range in this size centers on a blackwall BFGoodrich g-Force Phenom T/A, keeping the selection straightforward but still focused on correct rear fitment. This size matters when confirming the car’s 18-inch rear wheels and preserving the intended front-to-rear size relationship.
245/40R17 follows the same metric radial sizing format, with 245 millimeters of nominal section width, a 40-series profile, radial construction, and a 17-inch rim diameter. On the 2017 Mercedes-Benz SLC300, it is the rear size paired with the 17-inch front fitment, making it part of the car’s staggered 17-inch package rather than a stand-alone all-around choice. BFGoodrich offers this size in blackwall form across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This is the rear size to compare when the car has 17-inch wheels and you want to keep the proper width balance between front and rear tires.
Fitment on the 2017 Mercedes-Benz SLC300 is straightforward once the front-versus-rear layout is understood, but wheel diameter still matters because both 17-inch and 18-inch packages are used. Checking the exact sub-model position keeps the narrower front and wider rear sizes from being mixed during replacement.

2017 Mercedes-Benz SLC300 Base Front
The 2017 Mercedes-Benz SLC300 Base Front uses the 225-section front tire sizes, with one fitment for 17-inch wheels and another for 18-inch wheels, both in radial construction. Tire selection here starts with confirming wheel diameter, then comparing available series and sidewall treatments within the correct front size.
The 2017 Mercedes-Benz SLC300 Base Rear uses the wider 245-section rear tire sizes, again split between 17-inch and 18-inch radial fitments. That means rear replacement should focus first on wheel diameter, then on maintaining the staggered relationship and checking the product options offered in the matching 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 2017 Mercedes-Benz SLC300?
The 2017 Mercedes-Benz SLC300 uses a staggered tire setup rather than one universal size. Front fitments are 225/45R17 or 225/40R18, while rear fitments are 245/40R17 or 245/35R18, and all four sizes are radial tires.
The important step is matching the tire to both wheel diameter and axle position. A 17-inch front tire should not be selected for an 18-inch wheel, and the narrower front sizes should remain paired with the wider rear sizes unless the car has been modified and the full wheel-and-clearance setup has been checked.
What size rim does a 2017 Mercedes-Benz SLC300 use?
A 2017 Mercedes-Benz SLC300 uses either 17-inch or 18-inch rims, depending on the wheel package on the car. The 17-inch setup pairs 225/45R17 front and 245/40R17 rear, while the 18-inch setup pairs 225/40R18 front and 245/35R18 rear.
Rim diameter is the first fitment detail to confirm before choosing tires. Once that is settled, make sure the front and rear positions stay in the correct staggered arrangement, then compare the tire’s rim-width specification against the actual wheel to avoid choosing a tire that falls outside the wheel’s usable range.
Why does the 2017 Mercedes-Benz SLC300 have more than one tire size?
The 2017 Mercedes-Benz SLC300 has more than one tire size because it uses a staggered setup and was offered with two wheel diameters. The front axle uses a 225-section tire, the rear axle uses a wider 245-section tire, and each axle can be matched to either a 17-inch or 18-inch wheel package.
That means tire selection starts with identifying the exact wheels on the car, not simply the model name. Owners replacing only two tires should be especially careful, since the correct front and rear sizes are different, and mixing 17-inch and 18-inch fitments on the same axle would create an immediate mismatch.
Choosing the Right Tire
What should I consider when choosing a 2017 Mercedes-Benz SLC300 tire?
Start with the basics: front or rear position, 17-inch or 18-inch wheel diameter, and the exact size required for that axle. The 2017 Mercedes-Benz SLC300 uses radial tires throughout, so the decision usually comes down to choosing the right size first and then comparing the available tire series, sidewall style, and rim-width compatibility.
From there, think about how the car is used and how you want it to look. Some sizes offer broader brand and series selection than others, and the 225/45R17 front size adds sidewall appearance choices beyond blackwall. Matching the tire to the wheel and preserving the staggered setup matters more than choosing by brand name alone.
What sidewall styles are available for 2017 Mercedes-Benz SLC300 tires?
Most 2017 Mercedes-Benz SLC300 tire options are offered as blackwalls, which suits the car’s modern performance-roadster character. In the 225/45R17 front size, there are also raised white letter and redline choices, giving that specific fitment a broader appearance range than the other sizes used on the car.
Sidewall style should be chosen after the correct size and wheel diameter are confirmed. A blackwall keeps the look understated and contemporary, while raised white letter or redline can add a more distinctive visual accent. Since those alternate sidewall treatments appear in a front size only, owners should also consider how that look will pair with the rear tires.
What brands offer tires for the 2017 Mercedes-Benz SLC300?
Tire choices for the 2017 Mercedes-Benz SLC300 include BFGoodrich, Nitto, and Pro-Trac, depending on the exact size. BFGoodrich appears across all four primary fitments, Nitto is offered in select front sizes, and Pro-Trac appears in the 225/45R17 front size with alternate sidewall treatments.
Brand comparison is most useful after confirming the car’s wheel package and axle position. Some sizes have several series to choose from, while others are much more limited, so the real decision may be driven by size availability, sidewall appearance, or wheel compatibility rather than by trying to force the same brand or series at every corner.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Mercedes-Benz SLC300?
A period-style approach on a 2017 Mercedes-Benz SLC300 still begins with the correct staggered radial size for the wheel package on the car. Since this is a modern roadster, the most natural visual starting point is usually a blackwall radial in the proper front and rear sizes, especially on cars retaining their standard overall appearance.
Appearance choice becomes more personal in the 225/45R17 front size, where raised white letter and redline versions are also available. Those options create a more customized presentation rather than a strictly original-looking one, so buyers concerned with exact historical authenticity should compare their choice against vehicle literature, photos, or marque-specific reference material.
How does tire construction affect the appearance of a restored 2017 Mercedes-Benz SLC300?
On a 2017 Mercedes-Benz SLC300, tire construction is straightforward because the primary fitments are radial across all four sizes. That keeps the visual decision centered less on bias-ply versus radial shape and more on profile, wheel diameter, and sidewall treatment within the correct front and rear fitment.
The biggest appearance differences come from the 17-inch versus 18-inch package and from blackwall, raised white letter, or redline presentation where available. Keeping the correct axle-specific sizing preserves the car’s intended stance, while changing sidewall style can move the look from contemporary and restrained to noticeably more personalized.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz SLC300?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz SLC300 even when the tire size itself is correct. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and brake or body changes can all alter the space available for the car’s staggered front and rear radial tires.
That makes it worth checking more than just the numbers on the sidewall. The wheel’s actual diameter and width, the front-versus-rear position, and the clearance at full steering lock and suspension movement should all be confirmed. A tire that suits one SLC300 setup may need extra scrutiny on another that no longer retains stock wheel or suspension dimensions.
What should I inspect before driving a 2017 Mercedes-Benz SLC300 on new tires?
Before driving a 2017 Mercedes-Benz SLC300 on new tires, inspect inflation pressure, confirm that each tire is mounted on the correct axle and wheel diameter, and look over the wheels for damage or irregular seating. It also helps to verify that the staggered layout has been maintained from front to rear.
A quick clearance check is worthwhile before normal road use, especially if the car has aftermarket wheels or suspension changes. Look for any sign of rubbing at the fender, inner wheelhouse, or steering components, and recheck pressures after the first drives. Catching a fitment or mounting issue early is far easier than diagnosing uneven wear later.
How often should tires on a 2017 Mercedes-Benz SLC300 be inspected?
Tires on a 2017 Mercedes-Benz SLC300 should be inspected regularly, not just when tread appears low. A visual check for cuts, cracking, punctures, uneven wear, and air loss is smart before routine driving, and a closer inspection is especially worthwhile on cars that spend long periods parked between outings.
Roadsters often see seasonal or occasional use, so tire age and condition can matter as much as mileage. Checking pressure consistently and watching for wear differences between the front and rear axle can also reveal alignment or setup issues. Regular inspection helps preserve the handling balance expected from the car’s staggered radial tire arrangement.
