The 2007 Mercedes-Benz SLK350 sits in the era when compact luxury roadsters blended sharp handling, folding-hardtop convenience, and everyday drivability in one package. It is a modern performance-oriented SLK, so tire selection is less about vintage sizing systems and more about preserving the car’s staggered front-and-rear balance. This model uses 225/45R17 tires in front and 245/40R17 tires in back, both in radial construction on 17-inch wheels. Available choices include blackwall performance radials, plus raised white letter and redline treatments in the front size. The key is matching the correct axle position, wheel dimensions, and the appearance or driving character you want from the car.
Which Tire Size Is Right for The 2007 Mercedes-Benz SLK350
The 2007 Mercedes-Benz SLK350 uses two primary tire sizes, with 225/45R17 up front and 245/40R17 at the rear. Both are metric radial sizes on 17-inch rims, so the first step is confirming whether you are replacing a front tire or a rear tire, especially on a staggered-wheel setup where the sizes are not interchangeable side to side.
245/40R17 is a metric radial size where 245 represents nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2007 Mercedes-Benz SLK350, this size is used at the rear, giving the car its wider rear tire fitment. Product choice in this size centers on BFGoodrich performance-oriented series in blackwall form, with differences in rim-width compatibility, load specification, and series character. This is the size to confirm when replacing rear tires or restoring the intended front-to-rear stagger.
Fitment remains straightforward because the covered SLK350 configurations use the same staggered sizing pattern. Checking the exact sub-model still matters so the front and rear tire positions stay aligned with the wheel setup already on the car.

2007 Mercedes-Benz SLK350 Base Front
The 2007 Mercedes-Benz SLK350 Base Front uses the 225/45R17 radial size. Front tire selection should focus on maintaining the correct staggered setup while comparing available sidewall treatments, tire series, and wheel-width compatibility.
The 2007 Mercedes-Benz SLK350 Base Rear uses the 245/40R17 radial size. Rear tire choice is mainly about preserving the wider rear fitment and confirming that the wheel width and overall setup match the tire being considered.
The 2007 Mercedes-Benz SLK350 w/AMG Sport Pkg. Front also uses the 225/45R17 radial size. That keeps front fitment consistent, so the main decision becomes choosing the right tire series and appearance for the way the car is driven and presented.
The 2007 Mercedes-Benz SLK350 w/AMG Sport Pkg. Rear uses the same 245/40R17 radial size as the standard rear position. Tire selection here should keep the rear axle’s wider sizing intact and confirm compatibility with the actual wheel 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.

Tire Size & Fitment
What tire size fits a 2007 Mercedes-Benz SLK350?
The 2007 Mercedes-Benz SLK350 uses a staggered tire setup with 225/45R17 on the front and 245/40R17 on the rear. Both sizes are radial tires designed for 17-inch wheels, and that same front-and-rear sizing pattern applies to the Base and w/AMG Sport Pkg. configurations covered here.
That means the main fitment question is axle position, not just overall model year. Front and rear sizes should not be mixed accidentally, so check the tire being replaced, confirm the wheel diameter, and verify that the car still has its intended staggered-wheel arrangement before choosing a replacement.
What size rim does a 2007 Mercedes-Benz SLK350 use?
The 2007 Mercedes-Benz SLK350 uses 17-inch rims with both of its primary tire sizes. The front 225/45R17 and rear 245/40R17 are both built around a 17-inch wheel diameter, which keeps rim diameter consistent even though the front and rear tire widths and profiles differ.
Rim diameter is only one part of the fitment picture on a staggered car. Wheel width still matters, especially when comparing different tire series, so it is smart to confirm the actual front and rear wheel sizes on the car if the wheels may have been changed from the original setup.
Do all 2007 Mercedes-Benz SLK350 sub-models use the same tire size?
The covered 2007 Mercedes-Benz SLK350 sub-models use the same staggered sizing pattern rather than one universal tire at all four corners. The Base and w/AMG Sport Pkg. versions both use 225/45R17 in front and 245/40R17 in the rear, all in radial construction.
That makes sub-model fitment straightforward, but tire position still matters every time replacements are ordered or mounted. A quick check of the current wheel and tire arrangement helps confirm that the car has not been rotated into a mismatched setup or altered with aftermarket wheels that change the fitment requirements.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 and 245/40R17 tire set for a 2007 Mercedes-Benz SLK350?
Start with the correct staggered sizes: 225/45R17 for the front and 245/40R17 for the rear. From there, compare radial tire series, wheel-width compatibility, sidewall treatment, and any load figures that appear on the tire options being considered for each axle.
A good choice depends on how the SLK350 is actually used. Some owners want a straightforward blackwall performance radial, while others want a more distinctive look on the front through raised white letter or redline styling. Matching the tire to the wheel and maintaining the front-to-rear balance are more important than choosing by name alone.
What sidewall styles are available for 2007 Mercedes-Benz SLK350 tires?
The available sidewall styles for the 2007 Mercedes-Benz SLK350 include blackwall, raised white letter, and redline, depending on tire size and series. Blackwall choices appear in both primary sizes, while raised white letter and redline options appear in the 225/45R17 front size through the Pro-Trac Street Pro III line.
Sidewall style affects presentation more than fitment, but it can change the overall personality of the car. A blackwall keeps a cleaner modern appearance, while raised white letter or redline adds a more custom visual touch. The practical step is making sure the preferred sidewall style is offered in the correct axle-specific size.
What brands offer tires for the 2007 Mercedes-Benz SLK350?
Tires for the 2007 Mercedes-Benz SLK350 are available from BFGoodrich, Nitto, and Pro-Trac in the covered 17-inch sizes. BFGoodrich appears in both the front and rear fitments across multiple g-Force series, while Nitto and Pro-Trac add additional choices in the 225/45R17 front size.
Brand is only one part of the decision. It helps to compare each tire’s series, sidewall style, and wheel-width suitability so the tire matches both the car’s setup and the owner’s goals. On a staggered SLK350, keeping the front and rear choices properly aligned matters more than simply choosing a familiar brand name.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz SLK350?
Yes, modifications can affect tire fitment on a 2007 Mercedes-Benz SLK350 even when the tire sizes themselves look correct. Aftermarket wheels, altered wheel widths, suspension changes, lowering, or changes in alignment can all influence how 225/45R17 front and 245/40R17 rear tires sit in the car.
The safest approach is to confirm the actual wheel diameter and width on each axle before replacing tires. Clearance at the fender, inner wheelhouse, and steering range should also be checked, especially if the car has been customized. A staggered roadster leaves less room for guesswork than a square four-tire setup.
What should I inspect before driving a 2007 Mercedes-Benz SLK350 on new tires?
Before driving a 2007 Mercedes-Benz SLK350 on new tires, inspect inflation pressure, wheel hardware, valve stems, and the mounting direction if the tire design requires one. It also helps to confirm that the 225/45R17 tires are on the front and the 245/40R17 tires are on the rear.
A short visual check can prevent common problems after installation. Look for any rubbing at full steering lock, make sure the tires seat evenly on the wheels, and recheck pressure after the first drives. On a low-mileage car, it is also wise to inspect suspension bushings and alignment if the old tires showed uneven wear.
How often should tires on a 2007 Mercedes-Benz SLK350 be inspected?
Tires on a 2007 Mercedes-Benz SLK350 should be inspected regularly, not just when tread looks low. Collector-kept or fair-weather cars can still develop age-related concerns such as sidewall cracking, flat spotting, or slow air loss, especially if they spend long periods parked between drives.
A routine check of pressure, tread wear pattern, and general sidewall condition is worthwhile before normal use and especially before a longer trip. Any signs of bulges, cuts, repeated pressure loss, or contact marks deserve attention right away. Consistent inspection is particularly important on a staggered setup, since front and rear tires do different jobs.
