The 2007 Mercedes-Benz CLK350 belongs to the later years of the elegant CLK line, blending Mercedes-Benz grand touring character with a more modern performance-oriented stance. It is a car that balances everyday drivability with coupe refinement, so tire fitment matters for both appearance and road manners. This CLK350 uses a staggered radial setup with 225/45R17 in front and 245/40R17 in the rear on 17-inch rims. Available choices include blackwall performance radials, along with raised white letter and redline treatments in the front size. The key decision is matching the correct front and rear sizes while confirming wheel width and overall setup before replacement.
Which Tire Size Is Right for The 2007 Mercedes-Benz CLK350
The 2007 Mercedes-Benz CLK350 uses two primary tire sizes, and the difference is tied to position on the car rather than unrelated trim variations. Both are radial tires on 17-inch rims, so the first step is confirming whether you are replacing the front or rear tire, then checking that the wheel width and current vehicle setup still match the intended size.
225/45R17 is a metric radial size where 225 identifies section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 2007 Mercedes-Benz CLK350, this size serves the front position and supports the car's staggered 17-inch setup. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall styles joined by raised white letter and redline treatments in this size. It is the size to evaluate when front-end response, appearance, and proper wheel-width compatibility are the immediate replacement concerns.
245/40R17 is a metric radial size with a 245-millimeter section width, a 40-series profile, radial construction, and a 17-inch rim diameter. On the 2007 Mercedes-Benz CLK350, this size is used at the rear, giving the car a wider rear fitment than the front. Product choices in this size center on BFGoodrich performance-oriented series, all in blackwall form, with variations in rim-width compatibility and load specification. It deserves separate attention any time rear tires are being replaced, especially on a car that may have aftermarket wheels or suspension changes.
The covered CLK350 fitment is straightforward in layout but not identical at all four corners. Tire selection depends on confirming whether the tire is for the Base Front or Base Rear position, since each uses a different 17-inch radial size.

2007 Mercedes-Benz CLK350 Base Front
The 2007 Mercedes-Benz CLK350 Base Front uses the narrower of the two radial sizes in the staggered setup. That makes front-tire replacement a matter of choosing the correct 17-inch metric size, then comparing sidewall style, tire series, and wheel-width compatibility within that front application.
The 2007 Mercedes-Benz CLK350 Base Rear uses a wider radial size than the front, which is typical of a staggered performance-oriented arrangement. Rear tire selection should focus on the correct 17-inch size first, then on matching the wheel and overall vehicle setup rather than assuming the front and rear tires are interchangeable.
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 2007 Mercedes-Benz CLK350?
The 2007 Mercedes-Benz CLK350 uses a staggered tire setup with 225/45R17 in the front and 245/40R17 in the rear. Both are radial sizes mounted on 17-inch rims, so the car does not use the same size at all four corners.
That means replacement starts with confirming tire position before anything else. A front tire should be matched to the front size, and a rear tire should be matched to the rear size, while also checking that the current wheels are still the proper diameter and width if the car has been modified from its original-style setup.
What size rim does a 2007 Mercedes-Benz CLK350 use?
The 2007 Mercedes-Benz CLK350 uses 17-inch rims with both of its primary tire sizes. The front 225/45R17 and rear 245/40R17 are both built around the same 17-inch wheel diameter, even though the tire widths and profiles differ.
Wheel diameter is only one part of fitment, so it is still important to verify actual wheel width before choosing a replacement tire. Some available products support different rim-width ranges, and that matters on a staggered car where front and rear wheels may not be identical beyond sharing the same 17-inch diameter.
Why does the 2007 Mercedes-Benz CLK350 have more than one tire size?
The 2007 Mercedes-Benz CLK350 has more than one tire size because it uses a staggered fitment. The front position uses 225/45R17, while the rear uses 245/40R17, giving the rear a wider tire than the front.
That layout affects replacement planning because tire rotation and interchange assumptions do not apply the same way they would on a square setup. The practical approach is to identify the axle being serviced, confirm the wheel dimensions on that end of the car, and choose a tire that matches the intended front or rear application.
Choosing the Right Tire
What should I consider when choosing a 2007 Mercedes-Benz CLK350 tire?
Start with the correct position-specific size, since the 2007 Mercedes-Benz CLK350 uses 225/45R17 in front and 245/40R17 in the rear. From there, compare radial construction details such as wheel-width compatibility, load figures where stated, tire series, and the overall character of the available performance-oriented options.
Appearance may matter too, especially in the front size where blackwall, raised white letter, and redline treatments are available. A sensible choice depends on whether the goal is a more understated modern look, a sportier visual statement, or a balanced replacement that still suits the CLK350's grand touring personality.
What sidewall styles are available for 2007 Mercedes-Benz CLK350 tires?
Sidewall style depends on size. In the 225/45R17 front size, choices include blackwall, raised white letter, and redline, while the 245/40R17 rear size is represented by blackwall options.
That matters because a staggered setup can limit appearance matching if a distinctive sidewall treatment is only offered in one position. Anyone trying to maintain a consistent visual presentation should compare front and rear availability together before selecting a tire, rather than choosing one axle first and discovering a mismatch later.
What brands offer tires for the 2007 Mercedes-Benz CLK350?
Available tire brands for the 2007 Mercedes-Benz CLK350 include BFGoodrich, Nitto, and Pro-Trac, although the mix varies by size. The front 225/45R17 size has the widest spread of brand and sidewall choices, while the rear 245/40R17 size is centered on BFGoodrich offerings.
Brand should be considered alongside the actual tire series, sidewall style, and wheel-width compatibility rather than by name alone. On a staggered car, it is also worth deciding whether the goal is a matched brand front to rear or simply the right specification and appearance for each end of the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Mercedes-Benz CLK350?
A period-style choice for a 2007 Mercedes-Benz CLK350 usually begins with keeping the proper staggered 17-inch sizing in place: 225/45R17 front and 245/40R17 rear. Staying with the correct size relationship preserves the car's intended stance more effectively than choosing a visually interesting tire in the wrong dimensions.
From there, appearance comes down to sidewall treatment and overall presentation. Blackwall suits a restrained modern look, while raised white letter or redline in the front size can create a more customized visual effect, so buyers focused on authenticity should compare those choices against period photos, marque references, and the car's own history.
How does tire construction affect the appearance of a restored 2007 Mercedes-Benz CLK350?
On the 2007 Mercedes-Benz CLK350, the primary fitment is radial, so construction changes are less about converting from an older bias-ply format and more about selecting the right modern radial presentation. The visible effect comes mostly from profile, sidewall styling, and maintaining the proper front-to-rear stagger.
A restored or carefully kept CLK350 can look noticeably different if the stance is altered by mismatched sizes or inconsistent sidewall treatments. Keeping the correct 17-inch front and rear sizing relationship helps the car retain its intended proportions, while the sidewall choice determines whether the final look stays subtle or leans more toward custom styling.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz CLK350?
Yes, modifications can affect tire fitment on a 2007 Mercedes-Benz CLK350 even when the replacement tire size is correct on paper. Aftermarket wheels, changes in wheel width or offset, lowered suspension, and brake or body alterations can all change clearance at the fender, suspension, or steering components.
That is especially important on a staggered setup because the front and rear tires already serve different roles. A careful fitment check should include the actual wheel dimensions, tire-to-body clearance through steering and suspension travel, and enough room for safe operation before assuming any 17-inch tire in the correct nominal size will suit the car.
What should I inspect before driving a 2007 Mercedes-Benz CLK350 on new tires?
Before driving a 2007 Mercedes-Benz CLK350 on new tires, inspect mounting direction, tire pressure, valve stems, and basic clearance at both axles. It is also worth confirming that the front received 225/45R17 tires and the rear received 245/40R17 tires, since the car uses different sizes.
A short initial road check can reveal rubbing, vibration, or steering issues before the car is taken on a longer drive. Looking again after the first few miles for air loss, unusual contact marks, or uneven seating on the wheel helps confirm that the staggered setup was installed correctly and is working with the vehicle's current condition.
How often should tires on a 2007 Mercedes-Benz CLK350 be inspected?
Tires on a 2007 Mercedes-Benz CLK350 should be inspected regularly, especially if the car is driven seasonally or spends long periods parked. Pressure, tread wear, sidewall cracking, bulges, cuts, and signs of slow air loss are all worth checking even when the car has not covered many miles.
Regular inspection matters because low-use touring and collector-minded cars can age tires long before they look worn out. Looking over the front and rear tires separately is also smart on this staggered setup, since uneven wear patterns may point to alignment, suspension, or inflation issues that affect one axle differently than the other.
