The 2004 Mercedes-Benz E55 AMG sits at the point where executive luxury and supercharged V8 performance came together in a remarkably understated package. Built on the W211 platform, it is the kind of sedan that rewards careful attention to chassis setup, and tires are a big part of that equation. This car uses a staggered radial fitment with 245/40R18 in front and 265/35R18 in the rear, both on 18-inch wheels. Available choices include blackwall performance radials along with select redline and raised white letter options in the front size. The right decision comes down to preserving the staggered setup, matching the car’s intended look, and confirming wheel compatibility before changing anything.
Which Tire Size Is Right for The 2004 Mercedes-Benz E55 AMG
The 2004 Mercedes-Benz E55 AMG uses two primary tire sizes, and they are tied to position rather than trim variation. This is a staggered 18-inch radial setup, with one size for the front and a different size for the rear, so the first step is confirming that the car still has the correct wheel layout before selecting tires. Once that is established, the real choice becomes brand, tire series, sidewall style, and intended use.
245/40R18 is a metric radial size in which 245 represents section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2004 Mercedes-Benz E55 AMG, this is the front tire size in the staggered factory-style layout, so it plays a key role in steering response and front-end clearance. Available choices include blackwall performance tires from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III options in redline and RWL form. This size should be selected when the front wheel setup remains true to the original 18-inch staggered arrangement.
265/35R18 is also a metric radial size, with 265 indicating section width in millimeters, 35 identifying the aspect ratio, and 18 denoting the rim diameter in inches. On the 2004 Mercedes-Benz E55 AMG, this is the rear tire size, giving the car its wider back tire as part of the staggered performance fitment. Available products in this size center on blackwall radials from BFGoodrich and Nitto across several performance-oriented series. This size belongs on the rear axle when the car retains the correct staggered wheel package and has not been changed to a square setup.
Fitment on the 2004 Mercedes-Benz E55 AMG is straightforward in one sense and critical in another. The covered front and rear positions use different tire sizes, so identifying which end of the car you are replacing matters more than trim naming.

2004 Mercedes-Benz E55 AMG Base Front
The Base Front position uses the narrower front tire in the E55 AMG’s staggered radial setup. Tire selection here centers on maintaining the correct front size while comparing blackwall, redline, or raised white letter options where appearance and intended use matter.
The Base Rear position uses the wider rear tire that completes the car’s staggered 18-inch fitment. Choosing for the rear means matching the proper back size and reviewing performance-oriented radial options that suit the wheel width and intended road use.
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 2004 Mercedes-Benz E55 AMG?
The 2004 Mercedes-Benz E55 AMG uses a staggered tire setup with 245/40R18 on the front and 265/35R18 on the rear. Both sizes are radial tires designed for 18-inch wheels, and they are meant to work together as a matched front-to-rear fitment rather than as a single all-around size.
That means the first thing to confirm is whether the car still has its staggered wheel arrangement. If a previous owner changed wheels or converted the car to a square setup, the correct replacement tire choice may differ from the original front-and-rear sizing pattern.
What size rim does a 2004 Mercedes-Benz E55 AMG use?
The 2004 Mercedes-Benz E55 AMG uses 18-inch rims with both of its primary tire sizes. The front 245/40R18 and rear 265/35R18 each mount on an 18-inch wheel, which keeps overall fitment consistent while allowing the car to use a wider rear tire than front tire.
Rim diameter is only one part of the fitment picture, so wheel width still matters when choosing among available tires. It is smart to verify the actual front and rear wheel widths on the car before ordering replacement tires, especially if the car has aftermarket wheels.
Why does the 2004 Mercedes-Benz E55 AMG have more than one tire size?
The 2004 Mercedes-Benz E55 AMG has more than one tire size because it uses a staggered setup. The front axle carries 245/40R18 tires, while the rear axle uses 265/35R18 tires, giving the car a narrower front tire and a wider rear tire on the same 18-inch rim diameter.
For tire replacement, that means front and rear positions should not be treated as interchangeable just because both tires fit 18-inch wheels. Matching each axle to its proper size helps preserve the intended balance of clearance, wheel compatibility, and overall stance.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 tire for a 2004 Mercedes-Benz E55 AMG?
Choosing a 245/40R18 tire for a 2004 Mercedes-Benz E55 AMG starts with confirming that you are replacing a front tire in the original staggered setup. From there, the main differences are brand, tire series, sidewall style, and intended use, with options ranging from blackwall performance radials to redline and RWL selections.
Wheel width is also worth checking because the available products do not all share the same rim-width guidance. A buyer focused on a stock-style presentation may prioritize appearance, while a buyer more concerned with road manners or specialized use may focus more heavily on series and tire attributes.
What sidewall styles are available for 2004 Mercedes-Benz E55 AMG tires?
Sidewall choices for the 2004 Mercedes-Benz E55 AMG include blackwall across both primary sizes, with added redline and RWL options in the 245/40R18 front size. Blackwall is the dominant style in the available product range, while the appearance-oriented alternatives give the front size a more customized visual presentation.
That distinction matters because sidewall style affects the car’s look much more than its fitment category. Anyone trying to preserve a restrained modern AMG appearance may lean toward blackwalls, while a more personalized build may justify redline or raised white letter styling on the front axle.
What brands offer tires for the 2004 Mercedes-Benz E55 AMG?
Tires for the 2004 Mercedes-Benz E55 AMG are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. BFGoodrich and Nitto appear in both primary sizes, while M&H Racemaster and Pro-Trac are present in the 245/40R18 front size for buyers comparing specialized or appearance-oriented options.
Brand alone should not make the whole decision. It helps to compare the exact tire series, sidewall treatment, rim-width suitability, and the way each option aligns with how the car is actually driven, whether that means regular street use, a customized look, or a more specialized purpose.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Mercedes-Benz E55 AMG?
Yes, modifications can affect tire fitment on a 2004 Mercedes-Benz E55 AMG even when the tire sizes sound close to stock. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body or fender changes can all alter how a 245/40R18 front or 265/35R18 rear tire sits in the car.
A modified E55 AMG should be checked for steering clearance up front and inner and outer clearance at the rear before replacement tires are chosen. Verifying the actual wheel specifications on the car is especially important, because the original staggered arrangement may no longer be in place.
What should I inspect before driving a 2004 Mercedes-Benz E55 AMG on new tires?
Before driving a 2004 Mercedes-Benz E55 AMG on new tires, inspect wheel condition, confirm that front and rear sizes are mounted in the correct positions, and make sure inflation is set properly for the tire being used. It is also wise to look over suspension and alignment condition so the new tires begin service on a sound setup.
A quick clearance check is worthwhile before regular driving, especially on a staggered performance sedan. Turning the front wheels lock to lock and checking for rubbing, air loss, or abnormal contact points can help catch fitment issues early rather than after the tires have already been put into use.
How often should tires on a 2004 Mercedes-Benz E55 AMG be inspected?
Tires on a 2004 Mercedes-Benz E55 AMG should be inspected regularly, not just when tread looks low. Pressure, tread wear, sidewall condition, and any signs of cuts, bulges, cracking, or air loss all deserve routine attention, particularly on a car that may see seasonal use or long periods parked between drives.
A staggered setup makes inspection even more important because front and rear tires often wear differently. Checking the car before longer drives and after storage helps catch age-related issues or uneven wear early, giving the owner a better chance to correct alignment, inflation, or clearance problems before they become more serious.
