The 1999 Mercedes-Benz E55 AMG belongs to the era when AMG turned the W210 E-Class into a serious high-speed sport sedan without giving up everyday Mercedes composure. That balance matters when choosing tires, because this car uses a staggered 18-inch radial setup with 245/40R18 in front and 275/35R18 in the rear. Tire choice is less about finding one universal size and more about matching the front and rear fitment while deciding between blackwall performance radials or a more distinctive redline or raised white letter look up front. Wheel dimensions, intended road use, and any suspension or wheel changes should be checked before settling on a set.
Which Tire Size Is Right for The 1999 Mercedes-Benz E55 AMG
The 1999 Mercedes-Benz E55 AMG uses two primary tire sizes, both on 18-inch rims, because the car has a staggered front-and-rear setup. The first step is confirming position on the car, since 245/40R18 is used at the front and 275/35R18 at the rear. Once that is established, the decision shifts to tread type, brand, sidewall style, and wheel compatibility within each size.
245/40R18 is a metric radial size in which 245 identifies nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 1999 Mercedes-Benz E55 AMG, this size is used at the front and supports the car's staggered performance fitment. Available choices include blackwall performance tires from BFGoodrich, Nitto, and M&H Racemaster, along with Pro-Trac Street Pro III versions in redline and RWL form. This is the size to evaluate when preserving correct front fitment while tailoring appearance or intended street-versus-specialty use.
275/35R18 is a metric radial size where 275 refers to nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 18 marks the wheel diameter in inches. This size is used at the rear of the 1999 Mercedes-Benz E55 AMG, giving the car its wider rear stance and completing the staggered layout. Product choices center on blackwall radial performance tires from BFGoodrich and Nitto across several series. This rear size matters when maintaining the intended front-to-rear balance and checking wheel width before selecting among the available tire lines.
Fitment is straightforward once the tire position is identified, because the covered front and rear applications use different sizes on the same 18-inch rim diameter. Checking whether you are replacing the front pair or rear pair matters more here than trim variation.

1999 Mercedes-Benz E55 AMG Base Front
The 1999 Mercedes-Benz E55 AMG Base Front uses the narrower front tire size in the staggered radial setup. That makes front-tire selection a matter of preserving correct front fitment while choosing among available performance-oriented blackwall options or a more distinctive redline or RWL presentation.
The 1999 Mercedes-Benz E55 AMG Base Rear uses the wider rear tire size that completes the car's staggered arrangement. Rear selection should focus on the proper width and wheel compatibility, with available choices centered on blackwall radial performance tires.
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 1999 Mercedes-Benz E55 AMG?
The 1999 Mercedes-Benz E55 AMG uses a staggered tire setup rather than one size at all four corners. The front uses 245/40R18, while the rear uses 275/35R18, and both are radial tires designed for 18-inch wheels.
That means tire selection starts with identifying whether you are replacing the front pair, the rear pair, or the complete set. Mixing up the two sizes can upset the car's intended fitment, so it is worth confirming wheel position, checking the actual wheel dimensions on the car, and verifying that no aftermarket wheel or suspension changes have altered the original setup.
What size rim does a 1999 Mercedes-Benz E55 AMG use?
Both primary tire sizes for the 1999 Mercedes-Benz E55 AMG use an 18-inch rim diameter. The front 245/40R18 and rear 275/35R18 share that same wheel diameter even though the tires differ in width and profile.
Rim diameter is only part of the fitment picture on this car, because wheel width also matters with a staggered setup. Before choosing tires, confirm that the wheels on the car are still the correct 18-inch diameter and that their widths fall within the usable range for the front and rear tire sizes you plan to mount.
Why does the 1999 Mercedes-Benz E55 AMG have more than one tire size?
The 1999 Mercedes-Benz E55 AMG has more than one tire size because it uses a staggered fitment. The front axle carries 245/40R18 tires, while the rear axle uses wider 275/35R18 tires, so the car is not meant to run the same size at all four corners.
That arrangement makes it important to order and mount tires by position rather than treating the car like a square setup sedan. A careful check of front-versus-rear wheel width, clearance, and any prior modifications will help avoid fitment mistakes and preserve the overall stance and balance expected from the E55 AMG layout.
Choosing the Right Tire
What should I consider when choosing tires for a 1999 Mercedes-Benz E55 AMG?
Start with the correct staggered sizes: 245/40R18 for the front and 275/35R18 for the rear. From there, compare tire construction, intended use, brand, tire series, sidewall style, and wheel-width compatibility so the tires match both the car and how it will be driven.
This matters because the available choices are not all aimed at the same purpose. Some options lean toward performance street driving, one 245/40R18 option is a drag-oriented radial, and the front size also includes appearance-driven redline and RWL versions. Matching the tire to the wheel and the role of the car will produce a more coherent result than choosing by size alone.
What sidewall styles are available for 1999 Mercedes-Benz E55 AMG tires?
Blackwall is the main sidewall style offered for the 1999 Mercedes-Benz E55 AMG across both primary tire sizes. In the 245/40R18 front size, there are also Pro-Trac Street Pro III options with redline and RWL sidewall treatments for a more distinctive appearance.
Sidewall style mainly affects presentation rather than the basic fitment, but it can change the personality of the car considerably. A blackwall keeps the look understated and performance-oriented, while redline or raised white letter styling adds a more custom visual statement. It is still important to keep the correct front and rear sizes paired with the right wheel locations.
What brands offer tires for the 1999 Mercedes-Benz E55 AMG?
Tires for the 1999 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 represented in the 245/40R18 front size.
Brand comparison is most useful when it is tied to tire type and intended use rather than name alone. Some options focus on performance street driving, one front tire is drag-oriented, and some front choices also bring specific sidewall styling into the decision. The right choice depends on whether road use, appearance, or specialty use is the priority.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Mercedes-Benz E55 AMG?
Yes, modifications can affect tire fitment on a 1999 Mercedes-Benz E55 AMG even when the tire sizes remain close to the original staggered setup. Aftermarket wheels, altered offsets, suspension changes, or body modifications can all change the clearance available for 245/40R18 front and 275/35R18 rear tires.
A car that sits lower or runs non-original wheels deserves extra checking before new tires are mounted. Measure actual wheel diameter and width, inspect inner and outer clearances, and confirm steering lock and rear suspension travel. Those checks matter more on a staggered performance sedan because a small change in wheel setup can affect fitment at one end of the car first.
What should I inspect before driving a 1999 Mercedes-Benz E55 AMG on new tires?
Before driving, inspect wheel condition, mounting direction if applicable, tire pressure, valve stems, and basic clearance at the front and rear. It is also smart to confirm that the 245/40R18 tires are on the front axle and the 275/35R18 tires are on the rear axle.
A short visual check after installation can prevent simple but costly mistakes on a staggered setup. Look for rubbing at full steering lock, verify that the tires seat evenly on the wheels, and make sure there are no cuts, bulges, or signs of air loss. After the first drive, recheck pressure and inspect for any fresh contact marks.
How often should tires on a 1999 Mercedes-Benz E55 AMG be inspected?
Tires on a 1999 Mercedes-Benz E55 AMG should be inspected regularly rather than only when tread looks worn. Pressure, tread condition, uneven wear, sidewall cracking, cuts, and any slow air loss are worth checking often, especially on a performance sedan that may spend long periods parked between drives.
Routine inspection helps catch age and storage problems that can appear before the car sees many miles. A monthly pressure and condition check is a sensible habit, with a closer inspection before longer trips or spirited road use. Cars stored near heat, sunlight, or ozone-producing equipment also benefit from more careful monitoring between outings.
