The 2010 Mercedes-Benz C300 sits in the W204 generation, a compact luxury sedan known for combining everyday usability with the balanced road manners buyers expect from a modern Mercedes-Benz. Tire choice on this car is more configuration-specific than it first appears, because the C300 can use either a square 225/45R17 setup or a staggered Sport arrangement with 225/40R18 or 225/45R17 in front and 245/40R17 or 255/35R18 in the rear. All primary fitments are radial, so the key decisions center on identifying the exact sub-model, confirming wheel diameter, and choosing the right brand, series, and sidewall treatment for the way the car is used.
Which Tire Size Is Right for The 2010 Mercedes-Benz C300
Four primary tire sizes apply to the 2010 Mercedes-Benz C300, and the correct one depends on whether the car is a Luxury model or a Sport configuration with front and rear staggered fitment. The first step is confirming both the exact sub-model and whether the car is on 17-inch or 18-inch wheels. Once that is settled, the real comparison shifts to tread category, brand, sidewall style, and wheel-width compatibility within the correct radial size.
225/40R18 is a metric radial size that combines a 225-millimeter section width with a lower 40-series profile on an 18-inch wheel. On the 2010 Mercedes-Benz C300, it serves as a front tire size for certain Sport configurations using 18-inch staggered wheels. Product choices center on blackwall performance-oriented radials from BFGoodrich and Nitto across several g-Force and NT555 G2 series offerings. This size is the right one to consider when the car has 18-inch Sport front wheels and the goal is to preserve the intended front-to-rear sizing relationship.
245/40R17 is a metric radial size with a wider 245-millimeter section width, a 40-series profile, and a 17-inch rim diameter. On the 2010 Mercedes-Benz C300, this size is used at the rear on certain 17-inch Sport staggered setups rather than as a universal all-around fitment. Available options are blackwall radials from BFGoodrich in multiple g-Force series, giving buyers a few ways to compare construction details and rim-width requirements within the same size. It is the rear size to evaluate when maintaining a staggered 17-inch Sport wheel package matters more than simply matching front tire dimensions.
255/35R18 is a metric radial size that uses a 255-millimeter section width, a short 35-series profile, and an 18-inch wheel diameter. On the 2010 Mercedes-Benz C300, it functions as the rear tire size for certain 18-inch Sport staggered applications, where it pairs with a narrower front tire. Available choices are blackwall radials from BFGoodrich and Nitto, including multiple g-Force series and the NT555 G2. This is the size to verify when the car has 18-inch rear Sport wheels and the objective is to retain the proper staggered rear fitment rather than convert to a square setup.
Sub-model matters on the 2010 Mercedes-Benz C300 because Luxury versions use a straightforward 17-inch fitment, while Sport versions can use staggered front and rear tire sizes on either 17-inch or 18-inch wheels. Checking the exact sub-model and wheel setup first keeps front and rear sizing from being mixed incorrectly.

2010 Mercedes-Benz C300 4Matic Luxury
The 2010 Mercedes-Benz C300 4Matic Luxury uses a single 225/45R17 radial fitment rather than a staggered front-and-rear arrangement. Tire selection is therefore more about comparing available product lines, sidewall treatments, and rim-width compatibility within that 17-inch size.
The 2010 Mercedes-Benz C300 4Matic Sport Front can use either a 225/45R17 or 225/40R18 radial front tire, depending on the wheel package on the car. Choosing correctly starts with confirming whether the front wheel is 17 or 18 inches before comparing tire series and construction details.
The 2010 Mercedes-Benz C300 4Matic Sport Rear uses a wider rear fitment, with either 245/40R17 or 255/35R18 depending on the wheel diameter. That makes rear wheel confirmation especially important, since staggered sizing should be matched to the actual 17-inch or 18-inch setup on the car.
The 2010 Mercedes-Benz C300 Luxury uses 225/45R17, keeping fitment simple with one primary radial size on a 17-inch wheel. The decision usually comes down to selecting among available brands and sidewall styles while keeping the correct metric size and wheel compatibility.
The 2010 Mercedes-Benz C300 Sport Front uses either 225/45R17 or 225/40R18 at the front, depending on whether the car has 17-inch or 18-inch wheels. Front tire selection should follow the actual wheel diameter on the vehicle so the staggered setup remains properly matched.
The 2010 Mercedes-Benz C300 Sport Rear uses either 245/40R17 or 255/35R18 at the rear, paired with the corresponding front Sport size. Tire choice here is mainly about keeping the correct rear width and rim diameter for the wheel package already on the car.
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.

Common questions for the 2010 Mercedes-Benz C300 usually center on identifying the correct size for Luxury versus Sport fitment, understanding staggered front and rear setups, and comparing available radial tire choices by brand, sidewall style, and wheel compatibility.
Tire Size & Fitment
What tire size fits a 2010 Mercedes-Benz C300?
The 2010 Mercedes-Benz C300 uses four possible primary tire sizes: 225/45R17, 225/40R18, 245/40R17, and 255/35R18. Luxury models use 225/45R17, while Sport configurations can use staggered sizing with one front size and a wider rear size depending on whether the car has 17-inch or 18-inch wheels.
The practical step is to confirm the exact sub-model and the wheel diameter already on the car before selecting a tire. A Luxury setup is much simpler than a Sport staggered arrangement, and front and rear sizes should be matched to the wheel package rather than chosen by appearance alone.
What size rim does a 2010 Mercedes-Benz C300 use?
A 2010 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 the 225/40R18 and 255/35R18 sizes are for 18-inch wheels.
Wheel diameter should be verified before anything else, especially on Sport cars that may use staggered front and rear sizing. It is also worth checking actual wheel width, since the available tires in these sizes have different approved rim-width ranges and that can affect which products are suitable.
Why does the 2010 Mercedes-Benz C300 have more than one tire size?
The 2010 Mercedes-Benz C300 has more than one tire size because Luxury and Sport versions are not fitted the same way. Luxury models use a square 225/45R17 setup, while Sport versions can use staggered combinations with narrower front tires and wider rear tires on either 17-inch or 18-inch wheels.
That means the correct tire is tied to the exact configuration of the car, not just the model name on the trunk. Looking at the sub-model and wheel setup prevents mixing a rear Sport size into a square setup or ordering an 18-inch tire for a 17-inch wheel.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Mercedes-Benz C300?
Start with the exact tire size and wheel diameter your 2010 Mercedes-Benz C300 uses, then narrow the choice by whether the car is a square Luxury setup or a staggered Sport setup. From there, compare radial tire series, sidewall style, approved rim-width range, and any load figures shown for the specific product.
The best comparison is usually between products within the correct size, not across different sizes. A 17-inch Luxury car and an 18-inch Sport rear application call for different priorities, so confirming front and rear fitment first keeps the selection focused on tires that actually suit the wheel package.
What sidewall styles are available for 2010 Mercedes-Benz C300 tires?
Most 2010 Mercedes-Benz C300 tire options in these sizes use a blackwall sidewall. In 225/45R17, there are also Pro-Trac Street Pro III options with raised white letter and redline sidewall treatments, giving that size more appearance variety than the other primary C300 fitments.
Sidewall style should still be chosen within the correct tire size for the specific wheel and sub-model. On a square 225/45R17 setup, appearance options are broader, while staggered Sport combinations are more focused on blackwall performance-style radials that preserve the intended front and rear sizing.
What brands offer tires for the 2010 Mercedes-Benz C300?
Available tires for the 2010 Mercedes-Benz C300 come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across all four primary sizes in several g-Force series, Nitto is available in selected 17-inch and 18-inch sizes through the NT555 G2 line, and Pro-Trac appears in 225/45R17.
Brand choice is best treated as one part of the decision rather than the whole decision. Size, wheel diameter, approved rim width, sidewall presentation, and whether the car uses a square or staggered setup all matter first, and then the available brand and series options can be compared within that fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Mercedes-Benz C300?
A period-style choice for a 2010 Mercedes-Benz C300 usually starts with keeping the correct original-type size format for the car's actual wheel package, since all primary fitments here are modern metric radials. For a Luxury model, that often means focusing on 225/45R17, while Sport cars should retain the proper staggered front and rear sizing.
Appearance then comes from selecting the sidewall and tire series that best suit the look of the car without straying from the correct fitment. Buyers who want exact originality should compare tire choices against vehicle-specific documentation and marque references, especially if wheel packages may have been changed over time.
How does tire construction affect the appearance of a restored 2010 Mercedes-Benz C300?
On the 2010 Mercedes-Benz C300, construction is straightforward because the primary fitments are all radial. That means the visual effect comes less from choosing between bias-ply and radial construction and more from keeping the correct metric size, aspect ratio, and front-to-rear relationship for the sub-model.
Sidewall treatment still changes the presentation of the car, particularly in 225/45R17 where blackwall, raised white letter, and redline options exist. For a cleaner factory-inspired look, many owners stay with blackwall, while buyers aiming for a more individualized appearance may gravitate toward the available sidewall accents.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Mercedes-Benz C300?
Yes, modifications can affect tire fitment on a 2010 Mercedes-Benz C300 even when the tire size itself is one of the correct factory-type options. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, or body modifications can all change how much clearance the tire has at the fender, strut, and steering components.
That is especially important on Sport models with staggered front and rear sizing, where both diameter and width relationships matter. A modified car should be checked at full steering lock and through suspension travel so the tire choice matches the actual setup rather than only the original sub-model specification.
What should I inspect before driving a 2010 Mercedes-Benz C300 on new tires?
Before driving a 2010 Mercedes-Benz C300 on new tires, inspect the wheels for the correct diameter and condition, verify the tires match the front and rear positions, and check inflation pressure once the tires are mounted. It is also smart to look for any signs of rubbing, uneven suspension wear, or alignment issues that may have affected the previous tires.
A short initial drive followed by a second inspection helps catch issues early. Pay attention to steering feel, vibration, and any contact noises, and then recheck pressure and visual clearance. On staggered Sport setups, confirming that front and rear sizes were not accidentally reversed is particularly important.
How often should tires on a 2010 Mercedes-Benz C300 be inspected?
Tires on a 2010 Mercedes-Benz C300 should be inspected regularly, not just when tread looks low. Monthly pressure checks are a sensible baseline, and a visual inspection for cuts, bulges, irregular wear, and sidewall damage should be part of routine care, especially on a car that may sit for stretches between drives.
Longer intervals between inspections can allow small problems to become expensive ones, particularly on staggered setups where front and rear tires do not wear the same way. It also helps to inspect before a longer trip and after any impact with potholes or road debris, since wheel and tire damage is not always obvious immediately.
