The 2006 Mercedes-Benz CLK55 AMG blends the polished shape of the CLK coupe with the muscular character that defined AMG performance cars in the 2000s. It is the kind of car where stance, steering response, and road manners all depend on getting the tire setup right. This model uses a staggered radial fitment with 225/40R18 up front and 255/35R18 at the rear, both on 18-inch wheels. Available choices center on modern blackwall performance radials from BFGoodrich and Nitto across several series. The key decision is matching the correct front and rear sizes while keeping wheel width, overall setup, and intended use in mind.
Which Tire Size Is Right for The 2006 Mercedes-Benz CLK55 AMG
The 2006 Mercedes-Benz CLK55 AMG uses two primary tire sizes, and the difference is tied directly to its front and rear staggered setup. Both are radial tires for 18-inch wheels, so the first step is confirming which axle you are replacing before choosing a tire. Once that is settled, the decision shifts to tire series, brand preference, and wheel-width compatibility within the correct size.
225/40R18 is a metric radial size in which 225 denotes nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2006 Mercedes-Benz CLK55 AMG, this size serves the front position in the staggered setup and helps preserve the intended balance between steering feel and overall stance. Available choices include BFGoodrich and Nitto blackwall performance radials in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to focus on when replacing the front tires and confirming compatibility with the actual wheel width in use.
255/35R18 is a metric radial size where 255 represents nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 18 marks the wheel diameter. On the 2006 Mercedes-Benz CLK55 AMG, this is the rear tire size and it is visibly wider than the front, reflecting the car’s staggered performance fitment. BFGoodrich and Nitto both offer blackwall options in this size, with series including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. Choose this size only for the rear axle, and verify wheel width before moving between tire series.
Fitment is straightforward once the position on the car is identified, because this CLK55 AMG uses a staggered front-and-rear setup rather than multiple trim-specific tire packages. Checking whether you need the front or rear tire matters more than choosing between sub-model variations.

2006 Mercedes-Benz CLK55 AMG Base Front
The Base Front position uses the 225/40R18 radial size on an 18-inch wheel. Tire selection here is mainly about choosing among the available blackwall performance radial series while keeping the front wheel width and overall matched set in mind.
The Base Rear position uses the wider 255/35R18 radial size on an 18-inch wheel. That makes rear tire selection a matter of choosing the correct performance radial in the proper width range and keeping the staggered front-to-rear relationship intact.
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 CLK55 AMG?
The 2006 Mercedes-Benz CLK55 AMG uses a staggered tire setup with 225/40R18 on the front and 255/35R18 on the rear. Both are radial sizes for 18-inch wheels, so this car does not use the same tire size at all four corners in its standard fitment pattern.
That front-to-rear difference matters when replacing one pair or a full set. Matching the correct axle position is the first step, then the wheel width and the specific tire series should be checked so the new tires suit the actual wheel and overall setup on the car.
What size rim does a 2006 Mercedes-Benz CLK55 AMG use?
The 2006 Mercedes-Benz CLK55 AMG uses 18-inch rims with both of its primary tire sizes. The front 225/40R18 and rear 255/35R18 are both built around the same 18-inch wheel diameter, even though the two tires differ in width and profile.
Rim diameter is only part of the fitment picture on a staggered setup. Wheel width also needs to match the tire being considered, especially at the rear, and any car with replacement wheels should be checked carefully rather than assuming every 18-inch wheel is suitable.
Why does the 2006 Mercedes-Benz CLK55 AMG have more than one tire size?
The 2006 Mercedes-Benz CLK55 AMG uses more than one tire size because it has a staggered setup, with a narrower 225/40R18 tire in front and a wider 255/35R18 tire in the rear. Both sizes are part of the intended radial fitment for the car’s 18-inch wheel package.
That means tire selection starts with identifying the axle, not just the model year and nameplate. A wider rear tire can affect wheel compatibility and rear clearance, so maintaining the correct front and rear sizing relationship is important when replacing tires on a performance-oriented CLK55 AMG.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Mercedes-Benz CLK55 AMG?
Start by choosing the correct size for the correct axle: 225/40R18 for the front and 255/35R18 for the rear. After that, compare radial tire series, wheel-width compatibility, and useful specifications such as load figures where they are stated for the tire you are considering.
This car’s staggered setup makes balanced selection important, especially if replacing only one pair. Tire choice should also reflect how the CLK55 AMG is used, whether that means regular road driving, fair-weather use, or maintaining a matched performance-oriented appearance with blackwall tires.
What sidewall styles are available for 2006 Mercedes-Benz CLK55 AMG tires?
The available tires for the 2006 Mercedes-Benz CLK55 AMG use a blackwall sidewall style in both 225/40R18 and 255/35R18. That keeps the visual presentation consistent across the front and rear sizes and aligns with the modern performance character of this AMG coupe.
Since sidewall treatment does not vary here, the more useful comparison points are tire series, brand, and wheel-width range. Buyers looking for a matched appearance can focus on selecting the same family of front and rear tires rather than sorting through multiple whitewall or stripe options.
What brands offer tires for the 2006 Mercedes-Benz CLK55 AMG?
BFGoodrich and Nitto both offer tires for the 2006 Mercedes-Benz CLK55 AMG in its 225/40R18 front and 255/35R18 rear sizes. Within those brands, the available choices include several performance-oriented radial series rather than a single one-style-fits-all option.
Brand alone should not decide the purchase on a staggered setup like this. It is worth comparing the front and rear tire series together, checking wheel-width compatibility for each size, and making sure the combination supports the way the car is driven and the look you want to maintain.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Mercedes-Benz CLK55 AMG?
A period-style approach for a 2006 Mercedes-Benz CLK55 AMG starts with keeping the original staggered format intact: 225/40R18 in front and 255/35R18 in the rear, both as blackwall radials on 18-inch wheels. That preserves the car’s modern AMG-era stance more faithfully than changing to a non-staggered layout.
Within those sizes, the choice becomes one of tire series and overall presentation rather than vintage sidewall ornamentation. Buyers pursuing a highly exact restoration standard should still compare the finished look against marque references or period photos, since correct size alone does not settle every appearance detail.
Does correct tire fitment matter for a 2006 Mercedes-Benz CLK55 AMG restoration?
Correct tire fitment matters on a 2006 Mercedes-Benz CLK55 AMG because the car’s appearance is closely tied to its staggered 18-inch setup. The proper front 225/40R18 and rear 255/35R18 sizes help maintain the intended proportions, wheel fill, and front-to-rear visual balance of the car.
Fitment also matters beyond appearance, especially when replacement wheels or suspension changes entered the car’s history. A restoration-minded owner should verify wheel width, tire-to-body clearance, and a consistent front-and-rear tire family so the finished car looks coherent and remains usable on the road.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Mercedes-Benz CLK55 AMG?
Yes, modifications can affect tire fitment on a 2006 Mercedes-Benz CLK55 AMG even when the tire sizes remain 225/40R18 front and 255/35R18 rear. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or bodywork changes can all influence how those sizes sit and clear.
A car that still carries its original-style setup is easier to evaluate than one with changed hardware. Before ordering tires, measure the actual wheels on the car and check for steering, inner-fender, and suspension clearance so the staggered fitment continues to work as intended.
What should I inspect before driving a 2006 Mercedes-Benz CLK55 AMG on new tires?
Before driving a 2006 Mercedes-Benz CLK55 AMG on new tires, inspect the wheels for damage, confirm that the front and rear sizes were mounted in the correct positions, and check tire pressure carefully. It is also wise to look over suspension and steering components that influence how a staggered performance setup behaves.
A short road test should be used to catch any rubbing, vibration, or alignment-related pull early. On a car like the CLK55 AMG, proper condition of the wheels and chassis matters almost as much as the tire itself, especially when the front and rear sizes are different.
How often should tires on a 2006 Mercedes-Benz CLK55 AMG be inspected?
Tires on a 2006 Mercedes-Benz CLK55 AMG should be inspected regularly, not just when tread looks worn. Frequent checks for pressure loss, uneven wear, cuts, bulges, and sidewall aging are especially important on a performance car that may see seasonal or lower-mileage use.
The staggered layout makes it useful to inspect front and rear tires as separate working positions rather than assuming they wear the same way. A quick visual check before longer drives and a closer inspection at routine service intervals can help catch fitment or condition issues before they become more serious.
