The 2013 Mercedes-Benz C300 sits in the modern sport-luxury sedan era where balanced road manners, precise steering, and year-round drivability were central to the car’s appeal. That makes tire fitment especially important, because this C300 uses several radial sizes across 17-inch and 18-inch wheel setups, including both square and staggered arrangements depending on sub-model position. Choices within those sizes include blackwall, raised white letter, and redline presentations, along with several performance-oriented tire series from BFGoodrich, Nitto, and Pro-Trac. The right selection starts with identifying the exact sub-model and wheel package, then matching the tire’s size, profile, and appearance to how the car is actually equipped and driven.
Which Tire Size Is Right for The 2013 Mercedes-Benz C300
The 2013 Mercedes-Benz C300 uses four primary tire sizes, and the right one depends on the exact sub-model and whether the car has 17-inch or 18-inch wheels. Some versions use the same size front and rear, while the Sport setup can use different front and rear sizes, so the first step is confirming both the sub-model and the wheel position before choosing a tire.
225/45R17 is a metric radial size where 225 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2013 Mercedes-Benz C300, this size is part of the 17-inch fitment and is used on the 4Matic Luxury as well as some Sport front applications. Available choices include blackwall, RWL, and redline sidewall treatments, along with tire series such as g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, g-Force Phenom T/A, and Street Pro III. It is the key size to verify when the car retains a 17-inch front or square-wheel setup.
225/40R18 follows the same metric radial format, with a 225-millimeter section width, a 40-series profile, and fitment on an 18-inch wheel. This size serves the front position on the 2013 Mercedes-Benz C300 4Matic Sport when equipped with the 18-inch setup, giving the buyer a lower-profile tire than the 17-inch alternative. Product choices center on blackwall performance-oriented radials from BFGoodrich and Nitto, including the g-Force Comp 2 AS, g-Force Sport Comp 2, NT555 G2, and g-Force Phenom T/A. It should be evaluated as a front Sport fitment rather than as a universal C300 size.
245/40R17 is a wider metric radial size, with 245 millimeters of section width, a 40-series profile, and a 17-inch rim diameter. On the 2013 Mercedes-Benz C300, this size belongs to the rear position on the 4Matic Sport when the car is using the 17-inch staggered arrangement. Available tires in this size are blackwall radials from BFGoodrich, with series including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. It matters most when matching rear fitment on a Sport car, since width and wheel position are part of the decision.
255/35R18 is a wider, lower-profile metric radial with a 255-millimeter section width, a 35-series profile, and an 18-inch wheel diameter. This size is used at the rear of the 2013 Mercedes-Benz C300 4Matic Sport when equipped with the 18-inch staggered package, pairing with a narrower front tire. Blackwall options are available from BFGoodrich and Nitto in several performance-focused series, including g-Force Sport Comp 2, g-Force Comp 2 AS, NT555 G2, and g-Force Phenom T/A. It is the rear size to confirm when the car has 18-inch Sport wheels rather than the 17-inch setup.
Tire fitment on the 2013 Mercedes-Benz C300 changes by sub-model and, in the Sport application, by front and rear wheel position as well. Checking the exact 4Matic Luxury or 4Matic Sport configuration is the easiest way to avoid choosing the wrong wheel diameter or mismatching a staggered setup.

2013 Mercedes-Benz C300 4Matic Luxury
The 2013 Mercedes-Benz C300 4Matic Luxury uses a straightforward 17-inch tire fitment with 225/45R17. Tire selection here is less about sorting through multiple primary sizes and more about choosing the right radial product, sidewall treatment, and overall driving character for the car’s current wheel setup.
The 2013 Mercedes-Benz C300 4Matic Sport Front can use either a 17-inch or 18-inch front tire size depending on the wheel package. The practical step is confirming wheel diameter first, then selecting a front tire that matches the profile and construction intended for that specific Sport arrangement.
The 2013 Mercedes-Benz C300 4Matic Sport Rear uses a wider rear tire than the front, with different sizes tied to 17-inch or 18-inch wheels. That means rear replacement should be handled as part of a staggered fitment check, especially if the car has had wheel changes or mixed tire replacements in the past.
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.
Best 2013 Mercedes-Benz C300 Tires for Sale
Available C300 tire choices cover all four primary sizes and include radial options from BFGoodrich, Nitto, and Pro-Trac. Buyers can compare blackwall designs across several g-Force and NT555 series, while 225/45R17 also adds RWL and redline sidewall alternatives for a more distinctive look.
Owners usually need to sort out exact tire size, 17-inch versus 18-inch wheel fitment, Sport front and rear differences, and how to compare the available radial tire lines. The questions below focus on those model-specific decisions, along with appearance choices, setup checks, and road-use inspection points.
Tire Size & Fitment
What tire size fits a 2013 Mercedes-Benz C300?
The 2013 Mercedes-Benz C300 uses four primary tire sizes: 225/45R17, 225/40R18, 245/40R17, and 255/35R18. The exact fitment depends on the sub-model and, on the 4Matic Sport, whether the tire is for the front or rear position.
That means there is not one universal C300 tire size for every car. The 4Matic Luxury uses 225/45R17, while the 4Matic Sport can use either a 17-inch or 18-inch front and rear combination. Check the wheel diameter and whether the car has a staggered setup before replacing a single tire or ordering a full set.
What size rim does a 2013 Mercedes-Benz C300 use?
A 2013 Mercedes-Benz C300 uses either 17-inch or 18-inch rims, depending on the sub-model and wheel package. The 225/45R17 and 245/40R17 sizes mount on 17-inch wheels, while 225/40R18 and 255/35R18 mount on 18-inch wheels.
Wheel diameter is the first thing to confirm because a tire for a 17-inch rim cannot be mounted on an 18-inch wheel, and vice versa. On Sport models, front and rear wheel positions may also use different tire widths, so it helps to confirm both the wheel size and whether the car is using a square or staggered arrangement.
Why does the 2013 Mercedes-Benz C300 have more than one tire size?
The 2013 Mercedes-Benz C300 has more than one tire size because fitment changes with the sub-model and wheel package. The 4Matic Luxury uses a 17-inch setup, while the 4Matic Sport can use either 17-inch or 18-inch front and rear combinations with wider rear tires.
That variation is typical of cars offered with different wheel packages and staggered Sport layouts. It is important not to assume that a size from one C300 configuration applies to another. Matching the tire to the actual wheel diameter, axle position, and current setup is especially important if the car has replacement wheels or a mixed set from previous service work.
Choosing the Right Tire
What should I consider when choosing a 2013 Mercedes-Benz C300 tire?
Start with the correct primary size for the car’s exact configuration, then compare tire construction, series, and wheel compatibility within that size. On the 2013 Mercedes-Benz C300, all primary fitments are radial, but the available choices still vary by profile, rim-width specification, load figures where stated, and overall product character.
A 4Matic Luxury owner may focus on 225/45R17 choices, while a 4Matic Sport owner needs to confirm front and rear sizing first. After that, compare the intended use of the car, the wheel package, and whether appearance matters as much as performance. That approach helps narrow the options without mixing 17-inch and 18-inch fitments or front and rear sizes.
What sidewall styles are available for 2013 Mercedes-Benz C300 tires?
Most available 2013 Mercedes-Benz C300 tires use a blackwall sidewall, which is the dominant presentation across all four primary sizes. In 225/45R17, there are also RWL and redline choices, giving that size more visual variety than the other C300 fitments.
Sidewall style matters mostly when the car uses 225/45R17 and the owner wants a more distinctive appearance. The other sizes center on blackwall performance radials, so the decision there is more about the tire series and wheel package than the sidewall look. It is worth confirming the actual front or rear size before choosing based on appearance alone.
What brands offer tires for the 2013 Mercedes-Benz C300?
Tires for the 2013 Mercedes-Benz C300 are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich covers all four primary sizes, Nitto appears in several of the C300 fitments, and Pro-Trac is offered in 225/45R17 with appearance-focused sidewall options.
Brand choice should come after confirming the correct tire size and wheel setup. A buyer comparing 225/45R17 has the broadest mix of brands and sidewall treatments, while some of the wider Sport rear sizes are more concentrated in blackwall offerings. Looking at brand together with tire series, rim-width fitment, and intended use gives a better comparison than brand alone.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Mercedes-Benz C300?
A period-style approach on a 2013 Mercedes-Benz C300 starts with keeping the correct factory-era sizing format for the car’s actual wheel package. Since this C300 uses modern metric radial sizes, the visual decision is usually less about changing construction and more about staying with the proper 17-inch or 18-inch profile and stance.
For owners who want a less anonymous look, 225/45R17 offers more sidewall character through RWL and redline options. Sport models with staggered front and rear sizes need extra care so the appearance remains balanced from axle to axle. If exact showroom-era presentation matters, compare the current setup against vehicle-specific photos or marque references before choosing a sidewall style.
How does tire construction affect the appearance of a restored 2013 Mercedes-Benz C300?
On the 2013 Mercedes-Benz C300, construction is less of an appearance divide than it would be on an older collector car because the primary fitments are already radial. The visible difference comes more from tire profile, width, and sidewall treatment than from choosing between bias-ply and radial construction.
That makes size accuracy especially important to the finished look. A mismatched front-to-rear setup, the wrong wheel diameter, or an unintended low-profile change can alter the car’s stance quickly. If the goal is a clean restoration-oriented presentation, keep the original sizing format for the sub-model and choose a sidewall style that suits the car without assuming every styling option is era-specific.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Mercedes-Benz C300?
Yes, modifications can affect tire fitment on a 2013 Mercedes-Benz C300. Aftermarket wheels, suspension changes, altered ride height, or spacer use can change the relationship between the tire, fender, and suspension, even when the tire size matches one of the original C300 fitments.
That matters most on 4Matic Sport models using wider rear tires or 18-inch wheels, where small setup changes can have a bigger effect on clearance. It is smart to confirm wheel diameter, width, and the car’s current front and rear arrangement before replacing tires. Checking lock-to-lock steering clearance and rear inner clearance helps avoid surprises after installation.
What should I inspect before driving a 2013 Mercedes-Benz C300 on new tires?
Before driving a 2013 Mercedes-Benz C300 on new tires, inspect the wheel size, verify that each tire is mounted in the correct front or rear position, and make sure inflation is set properly for the vehicle’s use. It also helps to look for any rubbing, uneven seating, or visible sidewall damage before road use.
A short, careful test drive is useful after installation, especially on a Sport model with staggered sizing. Listen for contact over turns or bumps, and recheck pressure once the tires have settled. If the car has recently had alignment work, suspension repairs, or wheel changes, a second inspection afterward can catch issues before they become irregular wear patterns.
How often should tires on a 2013 Mercedes-Benz C300 be inspected?
Tires on a 2013 Mercedes-Benz C300 should be inspected regularly for pressure loss, tread wear, cuts, bulges, and sidewall cracking. A monthly visual check is a sensible baseline, and the tires should also be checked before longer drives, after impacts, or anytime the car begins to feel different on the road.
Inspection is especially important if the C300 is driven infrequently or has a staggered Sport setup, because uneven wear can be easier to miss when front and rear sizes differ. Looking at the inside shoulder as well as the outer tread helps catch problems early. Consistent inspection also makes it easier to spot alignment or suspension issues before they damage a tire.
