The 2001 Mercedes-Benz S55 AMG sits at an interesting point in AMG history, pairing full-size S-Class luxury with the kind of V8 performance that made these sedans genuine autobahn bruisers. Buyers looking at one today usually care about more than simple replacement tires, because the car’s staggered setup is part of how it delivers its balance of grip, stance, and high-speed composure. This application uses radial 245/45R18 tires in front and 275/40R18 tires in the rear. Available choices include blackwall performance radials up front and a wider mix of blackwall, redline, and raised white letter styling in the rear. The right choice starts with preserving the correct front-to-rear sizing and confirming the exact wheel setup on the car.
Which Tire Size Is Right for The 2001 Mercedes-Benz S55 AMG
The 2001 Mercedes-Benz S55 AMG uses two primary tire sizes, with 245/45R18 on the front and 275/40R18 on the rear. Both are radial fitments on 18-inch rims, so the first step is confirming that the car still has its proper staggered wheel and tire arrangement rather than a modified square setup. Once that is established, the real decision becomes choosing the right product character, sidewall style, and performance-oriented series for each axle position.
275/40R18 is a metric radial size where 275 is the 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 S55 AMG, this is the rear tire size and it provides the wider half of the factory-style staggered arrangement. Product choices include blackwall performance tires from BFGoodrich and Nitto, along with Pro-Trac Street Pro III options in redline and raised white letter form. This size belongs on the rear position, so wheel width and axle placement should be confirmed before selecting among the available styles.
Fitment on the 2001 Mercedes-Benz S55 AMG is straightforward in one sense and very specific in another, because the covered positions use a staggered front and rear setup. Checking whether you are matching the front or rear application matters more here than choosing between trim variations.

2001 Mercedes-Benz S55 AMG Base Front
The 2001 Mercedes-Benz S55 AMG Base Front uses the narrower front tire fitment in radial construction on an 18-inch wheel. That makes front-axle selection mainly a matter of preserving the correct staggered setup and choosing among the available blackwall performance tire series.
The 2001 Mercedes-Benz S55 AMG Base Rear uses the wider rear tire fitment in radial construction on an 18-inch wheel. Rear tire selection therefore centers on keeping the proper axle-specific size while deciding whether a blackwall, redline, or raised white letter presentation suits the car best.
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.

Common questions for the 2001 Mercedes-Benz S55 AMG usually center on its staggered tire sizing, 18-inch wheel fitment, front-versus-rear selection, and how to choose between the available radial tire brands, series, and sidewall treatments.
Tire Size & Fitment
What tire size fits a 2001 Mercedes-Benz S55 AMG?
The 2001 Mercedes-Benz S55 AMG uses a staggered tire setup with 245/45R18 on the front and 275/40R18 on the rear. Both are radial sizes designed for 18-inch wheels, and they are not meant to be treated as interchangeable front-to-rear fitments on this application.
That means the first step is identifying which axle you are buying for and confirming that the car still has the intended staggered wheel arrangement. If the vehicle has been changed to aftermarket wheels or a square setup, wheel width and clearance should be checked before choosing either size.
What size rim does a 2001 Mercedes-Benz S55 AMG use?
The 2001 Mercedes-Benz S55 AMG uses 18-inch rims with both of its primary tire sizes. The front 245/45R18 and rear 275/40R18 fitments share the same rim diameter even though the rear tire is wider and lower in profile.
Matching the 18-inch diameter is only part of the fitment picture on this car. Front and rear wheel widths can differ on a staggered setup, so it is smart to confirm the actual wheel dimensions on the vehicle before selecting tires, especially if the car has had wheel changes over the years.
What does 245/45R18 mean on a 2001 Mercedes-Benz S55 AMG?
245/45R18 is a metric radial tire size. The 245 refers to nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2001 Mercedes-Benz S55 AMG, this size is used on the front.
Understanding that code helps prevent ordering the rear size by mistake, since the S55 AMG uses a wider 275/40R18 tire at the back. It also helps when comparing products, because two tires may share the same basic size while differing in series, sidewall treatment, load specification, and approved wheel-width range.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 and 275/40R18 tire setup for a 2001 Mercedes-Benz S55 AMG?
Start with the correct staggered arrangement, since the 2001 Mercedes-Benz S55 AMG uses 245/45R18 in front and 275/40R18 in the rear. After that, compare the available radial tire series by axle position, along with wheel-width compatibility, sidewall style, and any load figures shown for the specific tire.
A good choice depends on how the car is used and how original or personalized you want it to look. A buyer keeping the car close to its traditional performance-sedan presentation may stay with blackwalls, while someone after a more custom appearance may focus on the rear redline or raised white letter offerings.
What sidewall styles are available for 2001 Mercedes-Benz S55 AMG tires?
Sidewall choice varies by axle size on the 2001 Mercedes-Benz S55 AMG. The available 245/45R18 front tires are blackwall radials, while the 275/40R18 rear size is offered in blackwall as well as redline and raised white letter styles.
That difference matters if appearance is part of the decision, because the rear tire size offers much more styling variety than the front. Before mixing styles, make sure the overall look matches the character of the car and that the selected rear tire still suits the wheel width and intended use.
What brands offer tires for the 2001 Mercedes-Benz S55 AMG?
Tires for the 2001 Mercedes-Benz S55 AMG are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size and axle position. BFGoodrich and Nitto cover the blackwall performance-oriented front and rear fitments, while Pro-Trac appears in the rear size with additional sidewall styling choices.
Brand alone should not decide the purchase on this car. It is more useful to compare each tire by the exact front or rear size, series, wheel-width specification, sidewall presentation, and any load information attached to that individual product so the setup stays balanced and appropriate.
Restoration & Appearance
Which tire should I choose for a period-style 2001 Mercedes-Benz S55 AMG?
A period-style 2001 Mercedes-Benz S55 AMG starts with keeping the correct staggered 18-inch radial sizing, using 245/45R18 in front and 275/40R18 in the rear. From there, blackwall performance radials usually give the most restrained, factory-inspired presentation for an early-2000s AMG sedan.
That said, period-style and exact originality are not always the same thing. If appearance accuracy matters at a higher level, compare the car against marque references, period photos, and vehicle-specific documentation, then choose a tire series and sidewall treatment that supports the car’s intended restoration standard.
How does tire construction affect the appearance of a restored 2001 Mercedes-Benz S55 AMG?
On a restored 2001 Mercedes-Benz S55 AMG, construction is less about bias-ply versus radial and more about selecting the right kind of radial tire for the car’s era and character. This application is radial-only, so the visual difference comes from tread and sidewall presentation rather than from changing construction type.
That makes sidewall style especially important when the goal is a restoration-oriented or period-inspired look. Blackwalls usually keep the appearance understated, while redline or raised white letter treatment on the rear size moves the car toward a more personalized presentation than many owners want for a traditional S-Class AMG.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2001 Mercedes-Benz S55 AMG?
Yes. Wheel changes, suspension lowering, spacer use, or a move away from the original staggered setup can all affect tire fitment on a 2001 Mercedes-Benz S55 AMG. Even when the tire size remains close to stock, wheel width and position can alter clearance at the fender, suspension, and steering components.
That is why the actual setup on the car matters more than the model name alone. A modified S55 AMG should have its front and rear wheel dimensions checked before tire selection, especially if the car has wider aftermarket wheels or has been converted from staggered to square fitment.
What should I inspect before driving a 2001 Mercedes-Benz S55 AMG on new tires?
Before road use, inspect the wheels for damage, confirm that the front and rear tire sizes are mounted in the correct positions, and check inflation pressure carefully. It is also smart to verify that the tires clear suspension and body components through steering movement and normal ride height.
An older high-performance luxury sedan can hide issues that affect tire behavior, including worn suspension parts or alignment problems. After installation, watch for vibration, uneven wear, or rubbing, and recheck pressure regularly so the new tires can deliver the balanced front-to-rear behavior this staggered setup is meant to provide.
How often should tires on a 2001 Mercedes-Benz S55 AMG be inspected?
Tires on a 2001 Mercedes-Benz S55 AMG should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Look for air loss, uneven tread wear, sidewall cracking, cuts, bulges, and any signs that front and rear tires may have been rotated or mounted in the wrong positions.
Inspection matters even more on collector-minded or low-mileage examples because age and storage conditions can affect a tire long before the tread looks worn out. A quick check before longer drives and a more thorough inspection at regular service intervals helps catch fitment or condition issues before they turn into road-use problems.
