The 2006 Mercedes-Benz CLK350 sits in the modern grand-touring side of the CLK lineup, blending coupe or cabriolet style with the balanced road manners expected from a Mercedes of the era. It is a vehicle where tire fitment plays directly into both appearance and handling feel. This CLK350 uses a staggered radial setup with 225/45R17 in front and 245/40R17 in the rear, both on 17-inch rims. Available choices range from blackwall performance-oriented series to Pro-Trac Street Pro III options with raised white letter or redline sidewalls. The key is matching the correct front and rear sizes first, then choosing the look and driving character that best suits the car.
Which Tire Size Is Right for The 2006 Mercedes-Benz CLK350
The 2006 Mercedes-Benz CLK350 uses two primary tire sizes, and they are tied to position rather than interchangeable across the car. Both are radial tires on 17-inch rims, with 225/45R17 used at the front and 245/40R17 used at the rear. The first step is confirming that the car still has its correct staggered wheel setup, because selecting the right tire depends on matching the size to the proper axle position.
225/45R17 is a modern metric radial size in which 225 represents the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2006 Mercedes-Benz CLK350, this size is used at the front, where correct steering response and clearance depend on keeping the intended front fitment. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, raised white letter, and redline sidewall treatments represented. This is the size to evaluate when the front tires need replacement or when the car's appearance matters as much as its road manners.
245/40R17 is a modern metric radial size that uses a wider 245-millimeter section width, a 40-series profile, radial construction, and a 17-inch rim diameter. On the 2006 Mercedes-Benz CLK350, this size is used at the rear, making it part of the car's staggered fitment rather than a universal all-around size. Current choices center on BFGoodrich performance-oriented series and blackwall presentation, with rim-width specifications varying by product. This rear size should be selected only after confirming the wheel remains the correct rear fitment and has not been changed during previous service or modification.
Fitment on the 2006 Mercedes-Benz CLK350 is straightforward in one sense and easy to misread in another. The covered sub-model positions use a staggered setup, so choosing tires depends on confirming whether the tire is for the front or rear of the car rather than treating both sizes as interchangeable.

2006 Mercedes-Benz CLK350 Base Front
The 2006 Mercedes-Benz CLK350 Base Front uses the smaller of the two primary radial sizes, making front-position fitment distinct from the rear. That means selection should focus on the proper front tire first, then on sidewall style, tire series, and wheel compatibility within that front size.
The 2006 Mercedes-Benz CLK350 Base Rear uses the wider rear radial size that completes the car's staggered 17-inch setup. Rear tire selection should stay tied to that position-specific size, with attention to rim-width suitability and maintaining the intended front-to-rear fitment relationship.
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 2006 Mercedes-Benz CLK350?
The 2006 Mercedes-Benz CLK350 uses a staggered tire setup with 225/45R17 at the front and 245/40R17 at the rear. Both are radial sizes mounted on 17-inch rims, so the car does not use one universal tire size at all four corners in this fitment.
That staggered arrangement means the first step is identifying whether the tire is for the front or rear axle before choosing a replacement. It is also worth confirming that the car still has the proper wheel setup, since aftermarket wheels or previous tire changes can blur the original front-to-rear sizing relationship.
What size rim does a 2006 Mercedes-Benz CLK350 use?
The 2006 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 rim diameter, even though the tire widths and profiles differ between the two positions.
Rim diameter is only one part of the fitment picture, so it helps to check wheel width as well before choosing among available products. A tire can share the correct 17-inch diameter and still require a different wheel-width range, especially on a staggered setup where front and rear tires are not the same size.
Why does the 2006 Mercedes-Benz CLK350 have more than one tire size?
The 2006 Mercedes-Benz CLK350 has more than one tire size because it uses a staggered arrangement, with 225/45R17 in front and 245/40R17 in the rear. The front and rear positions are assigned different sizes, so the tire choice depends on where the tire is being installed.
That matters because the two sizes are not simply alternate fitments for the same wheel position. Replacing tires on this car starts with confirming axle position, then verifying that the wheels and suspension still match the intended staggered configuration if the car has seen wheel changes or other modifications.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 or 245/40R17 tire for a 2006 Mercedes-Benz CLK350?
Start with the correct position-specific size, since the 2006 Mercedes-Benz CLK350 uses 225/45R17 in front and 245/40R17 in the rear. From there, compare radial tire series, sidewall presentation, rim-width compatibility, and product details such as weight or load figures where those specs are relevant to your setup.
Selection usually comes down to how the car is used and how you want it to look. A driver focused on a clean modern appearance may stay with blackwall tires, while someone chasing a more customized presentation may look closely at the front-size Pro-Trac options with raised white letter or redline sidewalls.
What sidewall styles are available for 2006 Mercedes-Benz CLK350 tires?
Sidewall choices for the 2006 Mercedes-Benz CLK350 include blackwall across both primary sizes, with additional raised white letter and redline options appearing in the 225/45R17 front size. That gives the front fitment the widest appearance range among the available products.
Sidewall style affects the car's visual character more than the raw fitment facts, so it should be chosen after the correct front or rear size is confirmed. A blackwall tire keeps the look restrained and contemporary, while raised white letter or redline sidewalls create a more noticeable custom impression on the front axle.
What brands offer tires for the 2006 Mercedes-Benz CLK350?
Tires for the 2006 Mercedes-Benz CLK350 are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across both front and rear fitments in multiple g-Force series, while Nitto and Pro-Trac expand the front 225/45R17 choices with additional series and appearance treatments.
Brand alone should not drive the decision on this car. It makes more sense to compare which brand offers the correct size for the axle position, then look at sidewall style, wheel-width suitability, and the overall character of the tire series so the front and rear selections remain appropriate for the CLK350's staggered setup.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Mercedes-Benz CLK350?
A period-style 2006 Mercedes-Benz CLK350 usually starts with preserving the correct staggered 17-inch sizing, using 225/45R17 in front and 245/40R17 in the rear. Within that fitment, blackwall radial tires typically maintain the most restrained presentation, while different performance series let you tailor the car without leaving the proper size family.
Appearance choices should follow the character you want the car to project rather than a blanket claim of originality. For a cleaner, more factory-inspired look, blackwall options are the natural place to begin, while custom-minded owners may choose a more expressive sidewall treatment on the front if visual distinction matters.
How does tire construction affect the appearance of a restored 2006 Mercedes-Benz CLK350?
Construction is straightforward on the 2006 Mercedes-Benz CLK350 because the primary fitments are radial tires in both front and rear sizes. That means the appearance difference comes less from bias-ply versus radial decisions and more from the tire series and sidewall treatment chosen within the correct radial sizes.
Visual character can still change noticeably even without changing construction type. A blackwall setup keeps the car closer to a restrained grand-touring presentation, while raised white letter or redline sidewalls on the available front-size options give the CLK350 a more customized look that may or may not suit a restoration-oriented goal.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Mercedes-Benz CLK350?
Yes, modifications can affect tire fitment on a 2006 Mercedes-Benz CLK350 even when the tire sizes look close to the original specification. Aftermarket wheels, different wheel widths, suspension changes, or altered ride height can all influence how the 225/45R17 front and 245/40R17 rear sizes sit in the wheel openings.
A modified car should be checked for wheel diameter, wheel width, and clearance at full steering lock and normal suspension travel before new tires are chosen. The CLK350's staggered setup adds another layer, since front and rear positions already differ, so any deviation from stock should be verified carefully rather than assumed.
What should I inspect before driving a 2006 Mercedes-Benz CLK350 on new tires?
Before driving a 2006 Mercedes-Benz CLK350 on new tires, inspect wheel condition, confirm the correct front and rear sizes, and make sure inflation is appropriate for the installed tires. It is also smart to look over valve stems, check for uneven suspension wear, and verify that the wheels are properly balanced and secured.
A short initial road test helps confirm that the tires clear properly and that the car tracks normally without rubbing or vibration. Any CLK350 that has been sitting for a while also deserves a close look at brake condition, alignment behavior, and general chassis health so new tires are not asked to mask another problem.
How often should tires on a 2006 Mercedes-Benz CLK350 be inspected?
Tires on a 2006 Mercedes-Benz CLK350 should be inspected regularly, especially because uneven wear can develop differently on the front 225/45R17 tires and the rear 245/40R17 tires. Routine checks should include tread condition, sidewall damage, air pressure, and any signs of vibration, pulling, or irregular wear.
Cars that are driven infrequently still need attention, since age and storage conditions can affect tire condition even when tread depth looks fine. A quick inspection before longer drives is worthwhile, and any sign of cracking, bulging, repeated air loss, or clearance issues deserves prompt evaluation before the car returns to regular road use.
