The 2017 Mercedes-Benz C350e blends the familiar comfort and refinement of the C-Class with plug-in hybrid technology, making it a more specialized modern Mercedes than a standard gasoline sedan. That mix of efficiency, luxury, and composed road manners puts extra importance on staying with the correct front and rear tire sizing. This car uses a staggered radial setup with 225/45R18 in front and 245/40R18 in the rear, both on 18-inch rims. Available choices include performance-oriented radial series, primarily in blackwall form, with additional redline and raised white letter styling on some rear-fitment options. The key is confirming front-versus-rear placement and matching the tire choice to the car's intended appearance and road use.
Which Tire Size Is Right for The 2017 Mercedes-Benz C350e
The 2017 Mercedes-Benz C350e uses two primary tire sizes, both in radial construction on 18-inch rims. The deciding factor is position on the car, since the front and rear fitments differ. Before choosing a tire, confirm whether you are replacing the front 225/45R18 or the rear 245/40R18, then compare the available series, sidewall treatments, and wheel-width compatibility within that exact size.
225/45R18 is a metric radial size in which 225 indicates nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2017 Mercedes-Benz C350e, this is the front tire size, so it needs to be selected as a front-position fitment rather than treated as an all-around setup. Available choices include BFGoodrich and Nitto options in blackwall styling across g-Force and NT555 G2 series. The main buying decision here is choosing the right front tire character while keeping the correct size and wheel fitment relationship intact.
245/40R18 is a metric radial size where 245 is the nominal width in millimeters, 40 is the aspect ratio, R marks radial construction, and 18 identifies the rim diameter in inches. On the 2017 Mercedes-Benz C350e, this size is used at the rear, making it part of the car's staggered front-to-rear fitment. Rear tire choices span BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and raised white letter sidewall treatments available depending on the series. This is the size to evaluate when rear traction, appearance, and wheel-width compatibility are the priority.
Fitment on the 2017 Mercedes-Benz C350e is straightforward once the position on the car is identified, because the covered front and rear configurations use different tire sizes. Checking the exact front-versus-rear application matters before ordering, since both sizes share the same 18-inch rim diameter but are not the same fitment.

2017 Mercedes-Benz C350e Base Front
The 2017 Mercedes-Benz C350e Base Front uses the 225/45R18 radial size. That makes the front-tire decision less about alternate sizing and more about selecting the right series and brand while keeping the intended staggered setup in place.
The 2017 Mercedes-Benz C350e Base Rear uses the 245/40R18 radial size. Rear selection adds more visible variety, including blackwall, redline, and raised white letter options, so appearance and intended use can influence the final choice within the correct 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 C350e?
The 2017 Mercedes-Benz C350e uses a staggered tire setup with 225/45R18 in the front and 245/40R18 in the rear. Both are radial tires mounted on 18-inch wheels, but they are different sizes for different positions on the car.
That means the first step is identifying whether you need front or rear tires rather than assuming one size fits the whole vehicle. A matched front-to-rear relationship matters on a staggered setup, so check the current wheel position, confirm the wheel diameter, and compare the replacement tire to the intended axle before making a final selection.
What size rim does a 2017 Mercedes-Benz C350e use?
Both primary tire sizes for the 2017 Mercedes-Benz C350e are built around an 18-inch rim diameter. The front 225/45R18 and rear 245/40R18 share that same wheel diameter even though the section width and profile differ.
Rim diameter is only part of the fitment picture, so it still helps to verify actual wheel width before choosing among available tires. Front products commonly fit a narrower wheel range than rear products, and any aftermarket wheel change can affect how the tire sits, clears the suspension, and maintains the intended staggered layout.
Why does the 2017 Mercedes-Benz C350e have more than one tire size?
The 2017 Mercedes-Benz C350e has more than one tire size because it uses a staggered setup: 225/45R18 at the front and 245/40R18 at the rear. The two sizes work together on the car rather than serving as interchangeable all-position fitments.
That distinction matters whenever only two tires are being replaced. Mixing up front and rear sizes can create fitment problems and alter the visual balance of the car, so check the sidewall on each wheel position and confirm whether the vehicle still has its original wheel arrangement or has been changed to a square setup by a previous owner.
Choosing the Right Tire
What should I consider when choosing tires for a 2017 Mercedes-Benz C350e?
Start with the correct position-specific size: 225/45R18 for the front and 245/40R18 for the rear. From there, compare tire series, brand, sidewall treatment, and wheel-width compatibility so the tire matches both the car's staggered layout and the way it will be driven.
A performance-oriented street car may call for a different product choice than a lightly used weekend vehicle, even within the same size. It also helps to compare details such as maximum load figures where stated, overall product character, and whether a purely blackwall appearance or a more stylized rear sidewall better suits the look you want.
What sidewall styles are available for 2017 Mercedes-Benz C350e tires?
Blackwall is the most common sidewall style across the available 2017 Mercedes-Benz C350e tire choices. On the rear 245/40R18 size, additional options include redline and RWL, or raised white letter, within the Pro-Trac Street Pro III line.
Sidewall style affects appearance more than basic fitment, so the first priority is still choosing the correct front or rear size. Once that is confirmed, blackwall keeps a cleaner modern look, while redline or raised white letter styling gives the rear fitment a more distinct visual presence without changing the required 18-inch tire size.
What brands offer tires for the 2017 Mercedes-Benz C350e?
Available tires for the 2017 Mercedes-Benz C350e come from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. BFGoodrich and Nitto appear in both front and rear sizes, while M&H Racemaster and Pro-Trac are part of the rear 245/40R18 product mix.
Brand selection matters less than matching the tire to the axle position, wheel size, and intended use. Some lines emphasize general street performance, while others bring a more specialized character or a stronger styling statement, so compare the tire series and specifications within the correct size instead of choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Mercedes-Benz C350e?
A period-style approach on a 2017 Mercedes-Benz C350e still begins with the correct staggered sizing: 225/45R18 front and 245/40R18 rear. Since this is a modern luxury-performance hybrid, a blackwall radial usually preserves the most natural contemporary appearance while staying close to the car's original visual character.
The decision becomes more appearance-driven on the rear size, where redline and raised white letter options are also available. Those can create a more customized presentation, but buyers pursuing an especially authentic look should compare against original delivery literature, marque references, or other vehicle-specific documentation before treating any sidewall treatment as historically exact.
How does tire construction affect the appearance of a restored 2017 Mercedes-Benz C350e?
Tire construction is simple on the 2017 Mercedes-Benz C350e because the primary fitment is radial front and rear. That means the appearance decision is shaped more by sidewall treatment and tire series than by choosing between bias-ply and radial construction.
For a restoration-oriented or preservation-minded car, the most restrained presentation usually comes from blackwall radials in the correct staggered sizes. Redline and raised white letter options on the rear can shift the look toward a more personalized style, so they are best chosen intentionally rather than simply because they share the same basic size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz C350e?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz C350e even when the tire size itself appears correct. Aftermarket wheels, suspension changes, altered ride height, or spacers can change how 225/45R18 front and 245/40R18 rear tires sit relative to fenders, steering components, and suspension parts.
A car that still uses its original wheel and suspension layout is easier to match, but any changed setup deserves a closer check. Measure wheel width, verify wheel diameter, look for clearance at full steering lock, and inspect rear fender and inner-suspension space before assuming that a standard replacement size will behave the same way.
What should I inspect before driving a 2017 Mercedes-Benz C350e on new tires?
Before driving a 2017 Mercedes-Benz C350e on new tires, inspect tire pressure, wheel condition, valve stems, and the basic condition of the suspension and brakes. It also helps to confirm that the front 225/45R18 tires and rear 245/40R18 tires are mounted in the correct positions.
A short visual check can prevent easy-to-miss problems such as rubbing, uneven stance, or a wheel-width mismatch. After installation, look for adequate clearance around the front strut area and rear inner wheelhouse, then drive cautiously at first and recheck inflation and lug torque after the initial road miles.
What should I check before a longer drive in a 2017 Mercedes-Benz C350e?
Before a longer drive, check tread condition, tire pressure, signs of air loss, and any visible sidewall damage on all four tires. On a 2017 Mercedes-Benz C350e, it is also important to confirm that the staggered front and rear sizes remain correctly matched and that no tire has been rotated into the wrong position.
Longer trips put more emphasis on heat, load, and sustained road speed, so a careful pre-drive inspection is worthwhile even on lightly used vehicles. Pay attention to irregular wear, vibration, or steering pull from previous drives, since those clues can point to alignment, balance, or suspension issues that should be addressed before extended use.
