The 2007 Mercedes-Benz CLK550 sits in the later years of the CLK line, blending Mercedes-Benz grand-touring character with V8 power and a chassis that rewards a properly matched tire setup. On this car, tire selection is not just about finding a 17-inch fitment, because the CLK550 uses a staggered arrangement with 225/45R17 in front and 245/40R17 in the rear. Both are modern metric radial sizes, so the key decision is matching each position correctly while weighing brand, series, and sidewall presentation where available. That matters whether the goal is preserving the car’s intended stance or choosing a road-use setup that suits its current wheels and condition.
Which Tire Size Is Right for The 2007 Mercedes-Benz CLK550
The 2007 Mercedes-Benz CLK550 uses two primary tire sizes, both on 17-inch rims, with 225/45R17 fitted at the front and 245/40R17 at the rear. Because this is a staggered setup rather than two interchangeable sizes, the first step is confirming which axle you are buying for. After that, the decision becomes choosing the right radial tire within each size, along with the brand, series, and sidewall style that best suits the car.
225/45R17 is a metric radial size in which 225 indicates section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2007 Mercedes-Benz CLK550, this size serves the front position in the staggered setup, so it should be treated as a front-axle fitment rather than a universal all-around size. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments across several tire series. It is the size to evaluate when front-end response, appearance, and proper axle-specific fitment are the priorities.
245/40R17 is also a metric radial size, with 245 indicating section width in millimeters, 40 as the aspect ratio, R for radial construction, and 17 for wheel diameter. On the 2007 Mercedes-Benz CLK550, this is the rear tire size in the factory-style staggered arrangement, giving it a different role from the front fitment. Available products in this size come from BFGoodrich in multiple g-Force series, all with blackwall styling. This is the size to focus on when confirming rear-wheel fitment, preserving the staggered stance, and matching the tire to the car’s rear axle requirements.
Fitment on the 2007 Mercedes-Benz CLK550 is straightforward once the wheel position is identified, because the covered sub-models split into front and rear applications rather than different trim-based tire packages. Checking the exact sub-model matters here because the front and rear tires are different sizes even though both use 17-inch radial fitments.

2007 Mercedes-Benz CLK550 Base Front
The 2007 Mercedes-Benz CLK550 Base Front uses the narrower front tire in the staggered setup, making this position-specific fitment important when replacing only one axle pair. Tire selection here centers on choosing the correct front size first, then comparing brand, series, and sidewall options that suit the car’s use and appearance.
The 2007 Mercedes-Benz CLK550 Base Rear uses the wider rear tire size, so it should not be treated as interchangeable with the front fitment. Rear tire selection should focus on the proper rear size and wheel compatibility, especially if the car has aftermarket wheels or any suspension changes that could affect clearance.
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.

Owners usually need to sort out the CLK550’s staggered front-and-rear sizing first, then compare radial choices by brand, sidewall style, and wheel compatibility. The questions below focus on exact size fitment, axle position, product selection, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2007 Mercedes-Benz CLK550?
The 2007 Mercedes-Benz CLK550 uses a staggered tire setup with 225/45R17 on the front and 245/40R17 on the rear. Both sizes are radial tires for 17-inch wheels, but they serve different axle positions and should not be treated as a single all-around fitment.
That means the first question is whether you are replacing the front tires, the rear tires, or the full set. Matching the correct size to the correct axle helps preserve the car’s intended stance and balance, and it is especially important to confirm the actual wheel setup if the CLK550 has been changed from its original 17-inch arrangement.
What size rim does a 2007 Mercedes-Benz CLK550 use?
The primary tire sizes for the 2007 Mercedes-Benz CLK550 both mount on 17-inch rims. The front 225/45R17 and rear 245/40R17 share the same rim diameter even though they use different section widths and profiles.
Rim diameter is only part of the fitment picture, so it is wise to confirm wheel width as well before selecting tires. That matters even more on a staggered car, because front and rear wheels may not be the same width, and aftermarket wheels can change the tire choices that make the most sense for each axle.
Why does the 2007 Mercedes-Benz CLK550 have more than one tire size?
The 2007 Mercedes-Benz CLK550 has more than one tire size because it uses a staggered arrangement, with one size at the front and a wider one at the rear. In this application, 225/45R17 is used on the front and 245/40R17 is used on the rear.
For the buyer, that means tire selection starts with wheel position rather than with a single size for the whole car. Replacing one pair requires care to avoid mixing the wrong size onto the wrong axle, and replacing all four is a good time to confirm that the wheels, suspension height, and current setup still match the intended staggered fitment.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 and 245/40R17 tire for a 2007 Mercedes-Benz CLK550?
Start with the axle-specific fitment, since the 2007 Mercedes-Benz CLK550 uses 225/45R17 in front and 245/40R17 in the rear. From there, compare radial tire series, brand options, sidewall appearance where available, and wheel-width compatibility so the tire matches both the car and the wheel it will be mounted on.
The front size offers broader style variety, including blackwall, raised white letter, and redline choices, while the rear size stays focused on blackwall performance-oriented options. It also helps to compare load figures where they are given, along with the intended use of the car, whether that means casual fair-weather driving, regular road use, or a more appearance-driven setup.
What sidewall styles are available for 2007 Mercedes-Benz CLK550 tires?
Sidewall style depends on tire size for the 2007 Mercedes-Benz CLK550. In 225/45R17, available styles include blackwall, raised white letter, and redline, while the 245/40R17 rear size is represented by blackwall options.
That makes sidewall appearance part of the decision if you want a more custom or period-inspired presentation on the front size. On a staggered car, it is worth thinking about the overall look of the full set, since mixing sidewall styles front to rear can change the visual balance even when the fitment is otherwise correct.
What brands offer tires for the 2007 Mercedes-Benz CLK550?
Available tires for the 2007 Mercedes-Benz CLK550 come from BFGoodrich, Nitto, and Pro-Trac, depending on size. The front 225/45R17 fitment has the widest brand spread, while the rear 245/40R17 choices shown here are centered on BFGoodrich offerings.
Brand is only one part of the comparison, so it helps to look at tire series, sidewall treatment, and rim-width suitability at the same time. A buyer replacing only the front or rear pair should also pay attention to how the chosen tire will visually and functionally match what remains on the opposite axle.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Mercedes-Benz CLK550?
A period-style 2007 Mercedes-Benz CLK550 still starts with the correct staggered fitment: 225/45R17 front and 245/40R17 rear. Since both are modern radial sizes, the appearance decision comes more from the tire series and sidewall treatment than from choosing between vintage bias-ply and radial construction.
Blackwall choices keep the look understated and in keeping with a factory-inspired presentation, while raised white letter or redline options in the front size move the car toward a more customized appearance. Keeping the proper front-to-rear size relationship matters most, because the staggered stance is part of how the CLK550 presents itself on the road.
How does tire construction affect the appearance of a restored 2007 Mercedes-Benz CLK550?
On a 2007 Mercedes-Benz CLK550, tire construction is less about vintage-style bias-ply appearance and more about selecting the right modern radial in each axle position. The visual character of the car is shaped more by sidewall style, tread presentation, and maintaining the proper staggered front and rear sizing.
For a restoration-minded owner, that means appearance choices should stay grounded in the car’s original-era modern performance-touring character rather than in much older styling cues. A clean blackwall setup usually supports that look, while more expressive sidewall treatments can suit a customized build if the wheel and tire proportions still remain consistent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz CLK550?
Yes. Modifications can affect tire fitment on a 2007 Mercedes-Benz CLK550, especially because the car uses a staggered 17-inch setup with different sizes front and rear. Aftermarket wheels, altered offsets, suspension lowering, or body changes can all influence how a 225/45R17 front or 245/40R17 rear tire sits in the wheelwell.
A modified car should be checked for wheel width, steering clearance, inner clearance, and fender clearance before a tire is chosen. Even when the nominal size stays the same, wheel changes can narrow the safe range of suitable tires, so confirming the actual setup on the car is more useful than assuming every CLK550 still matches stock dimensions.
What should I inspect before driving a 2007 Mercedes-Benz CLK550 on new tires?
Before driving a 2007 Mercedes-Benz CLK550 on new tires, inspect the wheels for damage, verify that the front and rear sizes were mounted in the correct positions, and make sure inflation is set properly for the installed tires. It is also wise to confirm that the tires clear the suspension and body through steering and normal ride movement.
A short initial drive should be followed by another look at air pressure and any signs of rubbing or uneven seating. Since this car uses a staggered arrangement, a front-to-rear mix-up is one of the simplest problems to avoid, and it is worth catching before the car is put into regular road use.
How often should tires on a 2007 Mercedes-Benz CLK550 be inspected?
Tires on a 2007 Mercedes-Benz CLK550 should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Look for air loss, uneven wear, cracking, cuts, bulges, and any signs that the front and rear tires are not wearing evenly within the staggered setup.
A quick visual check before driving and a more thorough inspection at routine service intervals is a sensible approach for a car like this. Low-mileage collector use can hide age-related deterioration, so condition matters just as much as tread depth, particularly on a performance-oriented Mercedes-Benz that places different demands on its front and rear tires.
