The 2001 Mercedes-Benz CL55 AMG blends the pillarless coupe luxury of the C215 chassis with AMG V8 performance, making it a grand touring car that asks more of its tires than a typical luxury coupe. Its stance and road manners depend on a staggered setup, with 245/45R18 at the front and 275/40R18 at the rear, both in radial construction on 18-inch wheels. That gives the tire decision a clear structure: preserve the intended front-to-rear sizing while choosing among available brands, series, and sidewall treatments. The right choice comes down to maintaining proper fitment, matching the car's use, and balancing appearance with modern road manners.
Which Tire Size Is Right for The 2001 Mercedes-Benz CL55 AMG
The 2001 Mercedes-Benz CL55 AMG uses two primary tire sizes, and the distinction matters because this is a staggered fitment rather than two interchangeable options. Both sizes are radial tires for 18-inch wheels, but the first step is confirming position on the car: 245/45R18 belongs at the front, while 275/40R18 belongs at the rear.
245/45R18 is a metric radial size in which 245 identifies the nominal section width in millimeters, 45 is the aspect ratio, R designates radial construction, and 18 is the wheel diameter in inches. On the 2001 Mercedes-Benz CL55 AMG, this size serves the front position and supports the car's intended staggered setup. Available choices center on blackwall radials from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. Selecting this size means preserving the correct front fitment while comparing series character, load figures where shown, and wheel-width compatibility.
275/40R18 is a metric radial size where 275 refers to nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On the 2001 Mercedes-Benz CL55 AMG, this is the rear tire size and is part of the car's wider rear fitment. Product choices include blackwall options from BFGoodrich and Nitto, along with Pro-Trac Street Pro III versions in redline and raised white letter styling. Choosing this size is about maintaining the proper rear footprint while deciding how much sidewall presentation and series selection matter for the car's look and use.
Sub-model fitment on the 2001 Mercedes-Benz CL55 AMG is straightforward in one sense and position-sensitive in another. The covered Base setup keeps the same 18-inch radial construction throughout, but front and rear tire sizes are different, so identifying wheel position matters before choosing a tire.

2001 Mercedes-Benz CL55 AMG Base Front
The 2001 Mercedes-Benz CL55 AMG Base Front uses the narrower of the two primary radial sizes in the staggered arrangement. That makes front tire selection less about choosing between fitments and more about keeping the proper front size while comparing available blackwall performance-oriented product lines.
The 2001 Mercedes-Benz CL55 AMG Base Rear uses the wider rear radial size that completes the car's staggered setup. Rear tire selection should stay focused on the correct rear fitment, with added room to consider blackwall, redline, or raised white letter sidewall presentation where appearance matters.
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 2001 Mercedes-Benz CL55 AMG?
The 2001 Mercedes-Benz CL55 AMG uses a staggered tire setup with 245/45R18 on the front and 275/40R18 on the rear. Both are radial tire sizes for 18-inch wheels, and they are meant for different positions on the car rather than as two interchangeable choices.
That means the first step is identifying whether you are replacing front tires, rear tires, or a complete set. A staggered arrangement should also prompt a check of the actual wheel setup on the car, especially if it has had aftermarket wheel changes, because correct diameter is only part of the fitment picture.
What size rim does a 2001 Mercedes-Benz CL55 AMG use?
The 2001 Mercedes-Benz CL55 AMG uses 18-inch rims with both of its primary tire sizes. The front 245/45R18 and rear 275/40R18 share the same rim diameter, which keeps wheel diameter consistent even though the car uses a wider tire at the rear.
Shared diameter does not make the front and rear tires interchangeable, since width and wheel-width requirements still differ by position. It is worth confirming the actual wheel width and setup already on the car before selecting replacements, particularly when replacing only one axle or when prior owners may have changed wheels.
Why does the 2001 Mercedes-Benz CL55 AMG have more than one tire size?
The 2001 Mercedes-Benz CL55 AMG has more than one tire size because it uses a staggered setup. The front position takes 245/45R18, while the rear uses 275/40R18, giving the car different tire widths at each end while retaining the same 18-inch rim diameter.
From a buying standpoint, that means tire choice starts with wheel position, not just year, make, and model. A car with the correct front size but the wrong rear size can still create fitment or handling mismatches, so owners should confirm that the vehicle still carries its intended staggered arrangement before mixing products or replacing only part of the set.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 and 275/40R18 tire set for a 2001 Mercedes-Benz CL55 AMG?
Start with the correct staggered fitment: 245/45R18 for the front and 275/40R18 for the rear. From there, compare radial tire series, wheel-width suitability, load figures where shown, and whether you want a coordinated look and character across all four tires.
A complete set should make sense as a system, not just as four matching diameters. Owners replacing one axle should pay close attention to remaining tire age, tread condition, and overall balance between front and rear, while anyone considering a style-driven rear tire should also think about whether the sidewall treatment complements the car's overall presentation.
What sidewall styles are available for 2001 Mercedes-Benz CL55 AMG tires?
Sidewall style depends on tire size and product line. Blackwall choices are available in both 245/45R18 and 275/40R18, while the 275/40R18 rear size also appears in Pro-Trac Street Pro III versions with redline and raised white letter sidewalls.
That gives the rear tire more room for appearance-based selection, but it is still important to keep the correct rear size and make sure the overall combination suits the car. A buyer focused on a uniform, understated look may stay with blackwalls, while a more custom presentation can make the alternate rear sidewall styles worth considering.
What brands offer tires for the 2001 Mercedes-Benz CL55 AMG?
The 2001 Mercedes-Benz CL55 AMG has tire options from BFGoodrich, Nitto, and Pro-Trac in its primary sizes. BFGoodrich appears in multiple g-Force series, Nitto offers the NT555 G2, and Pro-Trac covers part of the 275/40R18 rear fitment with Street Pro III options.
Brand choice should be tied to the exact tire size and the role that tire plays on the car. Since the CL55 AMG uses a staggered layout, it helps to verify that the selected front and rear products create a combination that makes sense for wheel-width compatibility, intended use, and the visual style you want from the finished setup.
Restoration & Appearance
Which tire should I choose for a period-style 2001 Mercedes-Benz CL55 AMG?
A period-style 2001 Mercedes-Benz CL55 AMG still starts with the proper staggered sizing: 245/45R18 in front and 275/40R18 in back. Since the car is a modern AMG luxury-performance coupe, the most natural appearance usually comes from keeping the correct proportions and selecting radial products that suit the original 18-inch presentation.
Appearance decisions then move to tire series and sidewall treatment rather than changing the basic fitment. Owners pursuing a more historically faithful result should compare the car to period photography, original sales material, or marque-specific references, especially before choosing more attention-grabbing rear sidewall styles such as redline or raised white letter.
How does tire construction affect the appearance of a restored 2001 Mercedes-Benz CL55 AMG?
On a 2001 Mercedes-Benz CL55 AMG, tire construction is less about a bias-ply-versus-radial debate and more about selecting the right type of radial within the car's intended modern fitment. The primary sizes are radial, so the visual effect comes mostly from sidewall shape, width relationship, and whether the rear sidewall stays blackwall or shifts to a styled treatment.
That makes proportion especially important on a restored or carefully presented car. Keeping the proper front and rear sizes preserves the staggered look the coupe was designed around, while changes in sidewall styling can either maintain a restrained luxury-performance appearance or push the car toward a more customized visual statement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2001 Mercedes-Benz CL55 AMG?
Yes. Wheel changes, altered offsets, suspension lowering, and other modifications can affect tire fitment on a 2001 Mercedes-Benz CL55 AMG even when the tire size itself appears correct. That matters even more on a staggered car, because front and rear clearances are already built around different widths.
A modified CL55 AMG should be checked for wheel width, brake clearance, inner suspension clearance, and outer fender room before replacement tires are chosen. Cars with aftermarket wheels also deserve a close look at the actual front and rear setup, since the factory-style 18-inch diameter alone does not confirm that every 245/45R18 or 275/40R18 arrangement will suit the car.
What should I inspect before driving a 2001 Mercedes-Benz CL55 AMG on new tires?
Before driving a 2001 Mercedes-Benz CL55 AMG on new tires, inspect tire pressure, wheel condition, lug hardware, and visible clearance at both the front and rear. It also makes sense to verify that the correct 245/45R18 front and 275/40R18 rear positions were maintained during installation.
A short, careful road test should follow, with attention to vibration, rubbing, pull, or unusual noise. Since this is a heavy, high-performance luxury coupe, any signs of uneven suspension wear, alignment issues, or old rubber elsewhere on the car are worth addressing early so the new tires are not asked to compensate for an unrelated chassis problem.
How often should tires on a 2001 Mercedes-Benz CL55 AMG be inspected?
Tires on a 2001 Mercedes-Benz CL55 AMG should be inspected regularly, especially because many examples are driven less often than ordinary daily vehicles. Pressure, tread wear, cracking, cuts, punctures, and signs of air loss all deserve routine attention, even when the car sees limited seasonal use.
Collector and specialty cars can age their tires out before they wear them out, so visual checks between drives are a smart habit. It is also helpful to inspect for uneven wear that may point to alignment or suspension issues, since the car's staggered front-and-rear setup makes it important to evaluate each axle on its own terms.
