The 2017 Mercedes-Benz C63 AMG blends compact executive-car proportions with serious AMG performance, making tire fitment especially important to how the car looks and responds on the road. This generation is known for a powerful rear-drive character and a staggered stance, so front and rear tire choices deserve equal attention. The 2017 Mercedes-Benz C63 AMG uses radial tires in four metric sizes, with either 18-inch or 19-inch wheel fitments depending on the setup. Available choices range from blackwall performance radials to select redline and raised white letter options in 18-inch front sizing. The key is confirming both wheel diameter and front-versus-rear size before comparing appearance, series, and intended use.
Which Tire Size Is Right for The 2017 Mercedes-Benz C63 AMG
The 2017 Mercedes-Benz C63 AMG uses four primary tire sizes, and the first step is confirming whether the car is running the 18-inch or 19-inch wheel setup. Fitment also follows a staggered pattern, with one size for the front and a wider size for the rear. Once wheel diameter and axle position are confirmed, the real choice becomes comparing radial tire series, sidewall styling, and product specifications within the correct size.
A 245/35R19 tire is a metric radial size with a 245-millimeter nominal section width, a 35-series profile, and fitment on a 19-inch rim. On the 2017 Mercedes-Benz C63 AMG, this size serves the front position on the 19-inch setup, so it should be matched to the correct axle rather than treated as a universal four-corner size. Available choices include BFGoodrich and Nitto blackwall radials in performance-oriented series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size is the right place to focus when keeping the car on a 19-inch front wheel while comparing brand and series differences.
A 245/40R18 tire uses the same 245-millimeter nominal width as the 19-inch front size, but with a 40-series profile sized for an 18-inch rim. On the 2017 Mercedes-Benz C63 AMG, it fits the front position when the car is equipped with the 18-inch staggered setup. Product choices are broader here, with blackwall options from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III versions in redline and raised white letter form. This size deserves a closer look when front-wheel diameter is 18 inches and sidewall presentation matters alongside performance and rim-width compatibility.
A 265/35R19 tire is a wider metric radial with a 265-millimeter nominal section width, a 35-series profile, and a 19-inch rim diameter. On the 2017 Mercedes-Benz C63 AMG, this is the rear size for the 19-inch setup, reflecting the car's staggered arrangement and the need to distinguish rear fitment from the narrower front tire. BFGoodrich and Nitto offer blackwall choices in series such as g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when confirming a 19-inch rear wheel and comparing available rear-tire options within the proper width range.
A 265/40R18 tire keeps the 265-millimeter nominal rear width but uses a taller 40-series profile on an 18-inch rim. On the 2017 Mercedes-Benz C63 AMG, it is the rear fitment for the 18-inch staggered setup, so it works as part of a front-and-rear combination rather than as a standalone sizing decision. The currently available product choice in this size is a blackwall BFGoodrich g-Force Phenom T/A radial. This size becomes the correct focus when the car has 18-inch rear wheels and the goal is to maintain the proper staggered relationship with the matching front tire.
Sub-model fitment on the 2017 Mercedes-Benz C63 AMG is straightforward in one sense and specialized in another: the distinction is front versus rear rather than separate trim levels. Checking the exact wheel diameter and axle position matters because the front uses a narrower tire and the rear uses a wider one.

2017 Mercedes-Benz C63 AMG Base Front
The Base Front position uses the narrower front tire sizing, with either an 18-inch or 19-inch radial depending on the wheel setup. That means the main selection step is confirming wheel diameter, then comparing front-tire series and sidewall treatments within the correct size.
The Base Rear position uses the wider rear tire sizing, again split between 18-inch and 19-inch radial fitments. Rear selection should stay tied to the matching staggered setup, with attention to wheel diameter and the available product choices in 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.
Best 2017 Mercedes-Benz C63 AMG Tires for Sale
Available 2017 Mercedes-Benz C63 AMG tire choices center on radial performance fitments from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Depending on size, buyers can compare blackwall options across several series, with redline and raised white letter choices appearing in 245/40R18.
Owners of a 2017 Mercedes-Benz C63 AMG usually need to sort out front-versus-rear sizing, 18-inch versus 19-inch wheels, and the differences between available radial tire series and sidewall styles. These FAQs focus on exact fitment, product selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2017 Mercedes-Benz C63 AMG?
The 2017 Mercedes-Benz C63 AMG uses a staggered tire setup with four primary sizes: 245/40R18 and 245/35R19 for the front, plus 265/40R18 and 265/35R19 for the rear. All of these are radial metric sizes, and the correct combination depends on whether the car is using 18-inch or 19-inch wheels.
That makes wheel diameter the first thing to confirm before choosing tires. Once that is settled, the next step is matching the narrower front size and wider rear size to the correct axle, since the C63 AMG does not use the same tire at all four corners in these fitments.
What size rim does a 2017 Mercedes-Benz C63 AMG use?
The 2017 Mercedes-Benz C63 AMG uses either 18-inch or 19-inch rims, depending on the tire size fitted to the car. The 245/40R18 and 265/40R18 sizes are for 18-inch rims, while 245/35R19 and 265/35R19 are for 19-inch rims.
A quick wheel check matters because the same car can appear with either diameter, and front and rear widths are different within each setup. Verifying the actual wheel diameter on the vehicle prevents ordering the right staggered pattern in the wrong rim size, especially on cars with replacement wheels.
Why does the 2017 Mercedes-Benz C63 AMG have more than one tire size?
The 2017 Mercedes-Benz C63 AMG has more than one tire size because it uses a staggered arrangement and two possible wheel diameters. The front position takes a 245-width tire, the rear takes a wider 265-width tire, and each axle can be paired with either an 18-inch or 19-inch version of that size family.
This means tire selection is not just about finding a size that mentions C63 AMG. The correct choice depends on the exact wheel setup on the car and whether the tire is intended for the front or rear, so checking both points before comparing brands or sidewall styles is essential.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 tire for a 2017 Mercedes-Benz C63 AMG?
A 245/40R18 tire on a 2017 Mercedes-Benz C63 AMG belongs on the front of the 18-inch setup, so size position is the first consideration. From there, the choice comes down to radial tire series, brand, sidewall style, and product details such as rim-width guidance, load figures where stated, and intended use.
This size has the broadest visible variety, including blackwall performance tires plus redline and raised white letter options. That makes it a good size for buyers balancing appearance with use, but the tire still needs to match the front axle, the 18-inch wheel, and the rest of the staggered setup.
What sidewall styles are available for 2017 Mercedes-Benz C63 AMG tires?
Sidewall style depends on size. Blackwall choices appear across all four primary sizes for the 2017 Mercedes-Benz C63 AMG, while redline and raised white letter options are available in 245/40R18 through the Pro-Trac Street Pro III series.
That means appearance options are broader on the 18-inch front fitment than on the other three sizes. Choosing a sidewall style should still begin with the correct axle and wheel diameter, then move to the look you want, whether that is a modern blackwall presentation or a more custom-oriented visual treatment.
What brands offer tires for the 2017 Mercedes-Benz C63 AMG?
Tires for the 2017 Mercedes-Benz C63 AMG are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on the size. BFGoodrich appears across all four primary sizes, while Nitto covers several of the 18-inch and 19-inch fitments, and M&H Racemaster and Pro-Trac appear in 245/40R18.
Brand choice should be filtered through the exact tire size first, because the same brand spread is not available in every fitment. Once the correct size is confirmed, compare the available series, sidewall style, and product specs within that size instead of assuming every brand offers the same configuration.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Mercedes-Benz C63 AMG?
A period-style approach on a 2017 Mercedes-Benz C63 AMG still starts with the correct staggered modern metric size for the wheel setup on the car. Since this is a late-model AMG performance sedan, the appearance decision is less about vintage construction and more about choosing a tire series and sidewall treatment that suits the car's visual direction.
Blackwall radials keep the most contemporary presentation, while 245/40R18 opens the door to redline or raised white letter styling for a more individualized look. Any appearance choice should stay secondary to correct front and rear sizing, proper wheel diameter, and the overall balance of the staggered setup.
How does tire construction affect the appearance of a restored 2017 Mercedes-Benz C63 AMG?
On the 2017 Mercedes-Benz C63 AMG, construction is simpler than on older collector cars because the primary fitments are radial throughout. That means the visual character comes more from profile, wheel diameter, and sidewall treatment than from choosing between bias-ply and radial construction.
For an appearance-conscious build, an 18-inch setup with available redline or raised white letter front options creates a different look than a blackwall-only 19-inch arrangement. The important thing is keeping the front and rear sizes aligned with the intended wheel package so the car's stance remains cohesive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz C63 AMG?
Yes, modifications can affect tire fitment on a 2017 Mercedes-Benz C63 AMG, even when the tire size itself is correct. Aftermarket wheels, altered offsets, suspension changes, lowering, or body modifications can change how a 245-width front tire or 265-width rear tire sits within the available space.
That matters most on a staggered car because front and rear tires already differ by width and may also differ by wheel diameter. Any modified setup should be checked for steering clearance, inner-wheel clearance, and fender room before settling on a tire choice, especially when the vehicle no longer carries its original wheel package.
What should I inspect before driving a 2017 Mercedes-Benz C63 AMG on new tires?
Before driving a 2017 Mercedes-Benz C63 AMG on new tires, inspect wheel condition, confirm the tires are mounted in the correct front and rear positions, and verify inflation pressure. It is also worth checking for bead seating issues, visible sidewall damage, and any rubbing at full steering lock or over suspension movement.
A short road test should follow, paying attention to vibration, pull, or contact noise. Since this car uses a staggered setup, a final check of front-versus-rear sizing is especially important, and any mismatch in diameter or axle placement should be corrected before regular road use.
How often should tires on a 2017 Mercedes-Benz C63 AMG be inspected?
Tires on a 2017 Mercedes-Benz C63 AMG should be inspected regularly, not just when tread appears low. Frequent checks for air loss, uneven wear, cuts, bulges, and sidewall damage are worthwhile on a performance-oriented car that uses low-profile radial tires in different front and rear sizes.
Monthly pressure checks and visual inspections are a sensible routine, with closer attention before longer drives or after seasonal storage. Because the C63 AMG may use either 18-inch or 19-inch staggered fitments, inspection is also a good time to confirm the axle positions remain correct after rotation errors or other service work.
