The 2008 Mercedes-Benz CLK350 sits in the final years of the elegant CLK coupe and cabriolet era, blending Mercedes grand-touring character with a more athletic stance than a traditional luxury coupe. Its tire fitment reflects that balance, using a staggered 17-inch radial setup with 225/45R17 in front and 245/40R17 in the rear. That means the real decision is not just finding a 17-inch tire, but choosing the correct front and rear sizes while considering brand, series, and sidewall presentation. For an original-style roadgoing setup or a more personalized look, wheel width, front-to-rear placement, and the car's current suspension and wheel configuration all deserve a careful check.
Which Tire Size Is Right for The 2008 Mercedes-Benz CLK350
The 2008 Mercedes-Benz CLK350 uses two primary tire sizes, both on 17-inch rims, with one size assigned to the front and a wider size assigned to the rear. The first step is confirming that the car still retains its staggered setup, because choosing the right tire depends on front-versus-rear position rather than trim variation. Once that is settled, the main comparison becomes brand, tire series, sidewall style, and wheel-width compatibility within each size.
225/45R17 is a metric radial size in which 225 indicates nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2008 Mercedes-Benz CLK350, this size is used at the front, where maintaining the correct front fitment is important to preserving the intended staggered arrangement. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, raised white letter, and redline sidewall treatments depending on the tire series. This size should be evaluated with attention to wheel width and front-end clearance, especially if the car has been altered from stock wheel or suspension specifications.
245/40R17 is a metric radial size with a wider nominal section width than the front tire, a 40-series profile, radial construction, and a 17-inch rim fitment. On the 2008 Mercedes-Benz CLK350, this size is used at the rear as part of the factory-style staggered arrangement, so it should be selected as a rear-position tire rather than treated as an all-around fitment. BFGoodrich offers this size across several g-Force series, all in blackwall form, with differences in series character and wheel-width specifications. Choosing this size starts with confirming rear placement and checking that the wheel matches the tire's rim-width requirements.
Fitment on the 2008 Mercedes-Benz CLK350 is straightforward once the position on the car is identified, because the covered front and rear applications use different tire sizes. Checking whether you are replacing a front or rear tire matters more than comparing trim differences.

2008 Mercedes-Benz CLK350 Base Front
The 2008 Mercedes-Benz CLK350 Base Front uses the narrower front tire size in the staggered 17-inch radial setup. Tire selection here centers on choosing the right 225/45R17 option for the front wheels while confirming wheel width and preserving front-end clearance.
The 2008 Mercedes-Benz CLK350 Base Rear uses the wider rear tire size that completes the car's staggered radial arrangement. Selection at the rear means choosing the correct 245/40R17 tire and verifying that the rear wheels and any suspension changes still suit that wider fitment.
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 2008 Mercedes-Benz CLK350?
The 2008 Mercedes-Benz CLK350 uses a staggered tire setup with 225/45R17 in front and 245/40R17 in the rear. Both are radial tire sizes designed for 17-inch wheels, so the car does not use the same size at all four corners in this covered configuration.
That makes front-versus-rear identification the first step before ordering replacements. A buyer should confirm the position of the tire being replaced, then verify that the car still has its original staggered wheel arrangement and has not been changed to a square setup, aftermarket wheel package, or altered suspension that could affect fitment.
What size rim does a 2008 Mercedes-Benz CLK350 use?
The 2008 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 a 17-inch wheel diameter, so rim diameter remains consistent even though the front and rear tire widths differ.
Rim diameter is only one part of the fitment picture, however, because wheel width also matters. Before choosing a tire, it is smart to confirm the actual width of the front and rear wheels on the car, especially if the CLK350 has aftermarket wheels or if one axle has been changed separately from the other.
Why does the 2008 Mercedes-Benz CLK350 have more than one tire size?
The 2008 Mercedes-Benz CLK350 uses more than one tire size because it has a staggered setup, with one size for the front axle and a wider size for the rear axle. In this arrangement, 225/45R17 serves the front and 245/40R17 serves the rear.
A staggered setup means tire selection is position-specific rather than interchangeable front to rear. That is why replacement starts with confirming where the tire is mounted, then checking the wheel width and any changes to ride height or suspension condition that could influence clearance with the correct front or rear size.
Choosing the Right Tire
What should I consider when choosing tires for a 2008 Mercedes-Benz CLK350?
Start with the correct staggered sizing: 225/45R17 for the front and 245/40R17 for the rear. From there, compare radial tire series, wheel-width compatibility, sidewall style where offered, and any product differences such as load figures or overall tire weight if those details matter for your intended use.
The best choice depends on how the CLK350 is driven and how closely the current car matches its original wheel setup. A daily-driven coupe with stock wheels may call for a different emphasis than a weekend car with appearance-focused sidewalls, so it pays to match the tire to both the axle position and the car's actual configuration.
What sidewall styles are available for 2008 Mercedes-Benz CLK350 tires?
Blackwall is the main sidewall style available for the 2008 Mercedes-Benz CLK350 tire sizes, and the front 225/45R17 also includes options in raised white letter and redline. Those sidewall choices appear within the available radial product lineup rather than as separate fitment categories for the car.
Sidewall style mainly affects presentation, so the right choice depends on whether the goal is a restrained modern look or a more customized appearance. It still needs to be the correct front or rear size, and buyers should confirm that the selected tire's wheel-width range suits the wheel it will actually be mounted on.
What brands offer tires for the 2008 Mercedes-Benz CLK350?
Available tires for the 2008 Mercedes-Benz CLK350 come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both front and rear sizes across several g-Force series, while Nitto and Pro-Trac are available in the front 225/45R17 size with different series and sidewall presentations.
Brand choice should be weighed alongside size position, tire series, and wheel compatibility rather than treated as the only decision. A useful approach is to narrow the correct front or rear size first, then compare the available brand offerings by series character, sidewall treatment, and any rim-width or load details that apply.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Mercedes-Benz CLK350?
A period-style 2008 Mercedes-Benz CLK350 tire choice starts with preserving the correct staggered 17-inch setup: 225/45R17 in front and 245/40R17 in the rear. Within that sizing, a blackwall radial usually maintains the cleanest era-appropriate presentation, while front-size RWL or redline options create a more customized look.
Because this is a modern Mercedes coupe rather than an early collector-era car, appearance usually comes down to how closely the car is being kept to its original visual character. Matching the front and rear sizes properly matters more than chasing a dramatic sidewall treatment, especially on a car meant to retain a balanced factory-inspired stance.
Does correct tire fitment matter for a 2008 Mercedes-Benz CLK350 restoration?
Correct tire fitment matters on a 2008 Mercedes-Benz CLK350 restoration because the car's stance and proportions depend on the proper staggered relationship between front and rear sizes. Using 225/45R17 in front and 245/40R17 in the rear keeps the tire presentation aligned with the way this CLK350 was configured.
Restoration-minded buyers should also pay attention to wheel diameter, wheel width, and sidewall appearance before making a final selection. If exact originality is a priority, marque-specific references and vehicle history are worth consulting, but even without that level of research, maintaining the correct front-rear size pairing is an important baseline.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mercedes-Benz CLK350?
Yes, modifications can affect tire fitment on a 2008 Mercedes-Benz CLK350 even when the tire size itself is correct. Aftermarket wheels, altered wheel widths, suspension changes, lowering, or previous alignment-related changes can all influence how a 225/45R17 front or 245/40R17 rear tire sits in the wheel opening.
A tire that matches the intended size still needs suitable wheel dimensions and adequate clearance in actual use. It is wise to inspect steering clearance at the front, check rear fender and suspension space, and confirm that both axle positions still reflect the staggered setup before replacing only one tire or one pair.
What should I inspect before driving a 2008 Mercedes-Benz CLK350 on new tires?
Before driving a 2008 Mercedes-Benz CLK350 on new tires, confirm that the front tires are 225/45R17 and the rear tires are 245/40R17, then check tire pressure, wheel hardware, and visible clearance around the suspension and fenders. A quick inspection for mounting direction and overall seating on the wheel is also worthwhile.
After installation, a short careful drive can reveal rubbing, vibration, or pull that was not obvious while the car was stationary. It also helps to recheck air pressure and visually inspect the tires again once the car has settled, especially if the CLK350 has not been driven recently or uses non-original wheels.
How often should tires on a 2008 Mercedes-Benz CLK350 be inspected?
Tires on a 2008 Mercedes-Benz CLK350 should be inspected regularly, not just when tread appears worn. Because this car uses a staggered setup, both front and rear tires deserve separate attention for pressure, uneven wear, cuts, bulges, cracking, and signs of air loss that may develop differently from axle to axle.
A practical routine is to look over the tires before longer drives and to give them a closer inspection at regular intervals during normal ownership. Cars that spend long periods parked benefit from extra checks, since age, flat spotting, and gradual pressure loss can matter just as much as mileage on a collector-minded coupe.
