The 2006 Mercedes-Benz S55 AMG sits at an interesting point in AMG history, blending full-size S-Class luxury with supercharged V8 power and a factory performance stance that depends on a staggered tire setup. On this car, tire selection is not just about getting the right 19-inch fitment, but about preserving the balance between front and rear sizing. The primary fitment uses 245/40R19 up front and 275/35R19 in the rear, both in radial construction. Available choices center on blackwall performance radials from BFGoodrich and Nitto across several series. For this S55 AMG, the key is matching the correct axle position, wheel width, and intended road use before choosing a tire.
Which Tire Size Is Right for The 2006 Mercedes-Benz S55 AMG
The 2006 Mercedes-Benz S55 AMG uses two primary tire sizes, both on 19-inch rims, with a staggered layout rather than a single all-around fitment. The first step is confirming whether you are replacing the front or rear tires, because 245/40R19 belongs on the front axle and 275/35R19 belongs on the rear. Once axle position is confirmed, the decision shifts to comparing radial tire series, brand options, and wheel-width compatibility.
245/40R19 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 40 is the aspect ratio, R designates radial construction, and 19 is the rim diameter in inches. On the 2006 Mercedes-Benz S55 AMG, this size serves the front axle and supports the car's staggered high-performance setup. Available choices in this size include BFGoodrich blackwall radials across the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This is the size to evaluate when maintaining correct front-end fitment, steering response, and wheel compatibility.
275/35R19 is a modern metric radial size where 275 indicates nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 19 identifies the rim diameter in inches. On the 2006 Mercedes-Benz S55 AMG, this is the rear tire size and it works with the wider rear wheel position in the car's staggered arrangement. Choices here include blackwall radial options from BFGoodrich and Nitto, with several performance-oriented series available. This is the size to confirm when replacing rear tires so the car retains its intended front-to-rear tire relationship.
Fitment on the 2006 Mercedes-Benz S55 AMG is straightforward in one sense and very specific in another: the covered configuration uses a front size and a separate rear size. Checking the exact axle position matters before selecting a tire, because the front and rear do not share the same dimensions.

2006 Mercedes-Benz S55 AMG Base Front
The Base Front position uses a 245/40R19 radial tire on a 19-inch rim as part of the S55 AMG's staggered setup. Tire selection here is mainly about choosing the right front-axle radial series while confirming wheel width and maintaining the intended front fitment.
The Base Rear position uses a 275/35R19 radial tire on a 19-inch rim and requires a wider fitment than the front. Choosing for this position means focusing on the correct rear size, matching the wheel correctly, and comparing the available blackwall performance radial options.
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 S55 AMG?
The 2006 Mercedes-Benz S55 AMG uses a staggered tire setup with 245/40R19 on the front and 275/35R19 on the rear. Both are radial sizes mounted on 19-inch rims, so this car does not use one tire size at all four corners.
That staggered arrangement means replacement starts with confirming axle position before choosing a tire. Mixing up the front and rear sizes can affect wheel compatibility and the intended balance of the car, especially if the S55 AMG has different wheels than stock or has been modified since new.
What size rim does a 2006 Mercedes-Benz S55 AMG use?
The 2006 Mercedes-Benz S55 AMG uses 19-inch rims with both of its primary tire sizes. The front 245/40R19 and rear 275/35R19 are both built around the same rim diameter, even though the widths differ between front and rear positions.
Rim diameter is only part of the fitment picture on this AMG. Wheel width still matters, particularly on a staggered setup, so it is worth checking the actual wheel installed on each axle before selecting tires, especially if the car has aftermarket wheels or a changed suspension stance.
Why does the 2006 Mercedes-Benz S55 AMG have more than one tire size?
The 2006 Mercedes-Benz S55 AMG uses more than one tire size because it has a staggered setup, with a narrower front tire and a wider rear tire. The front uses 245/40R19, while the rear uses 275/35R19, both in radial construction.
For the owner, that means tire choice is tied to position on the car rather than just year, make, and model. Replacing only one axle or rotating assumptions from a square setup can create confusion, so checking front and rear wheels separately is the practical step before ordering or mounting tires.
Choosing the Right Tire
What should I consider when choosing a 245/40R19 and 275/35R19 tire for a 2006 Mercedes-Benz S55 AMG?
Start with the correct axle size, since the 2006 Mercedes-Benz S55 AMG uses 245/40R19 in front and 275/35R19 in the rear. From there, compare radial construction details, wheel-width compatibility, tire series, and any load information that appears on the tire you are considering.
This car rewards careful matching because the front and rear tires play different roles in a staggered setup. It also helps to think about how the car is used, whether that is occasional fair-weather driving, regular street mileage, or a more performance-focused routine that makes tire series selection more important.
What brands offer tires for the 2006 Mercedes-Benz S55 AMG?
BFGoodrich and Nitto both offer tires for the 2006 Mercedes-Benz S55 AMG within the correct 19-inch fitments. BFGoodrich appears in both front and rear sizes, while Nitto is available in the 275/35R19 rear fitment.
Brand choice should still follow size and wheel compatibility first. Once the correct front or rear position is confirmed, comparing the available series within those brands can help narrow the field by intended use, tire character, and how closely you want the front and rear choices to align.
What tire series are available for the 2006 Mercedes-Benz S55 AMG?
The 2006 Mercedes-Benz S55 AMG has several tire series available in its correct sizes, including BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and the Nitto NT555 G2 in the rear size. All of these are radial blackwall options.
Series choice matters because even within the same size, tires can differ in focus and operating character. Looking at the exact front and rear fitments together is useful on a staggered car, since the best choice often comes from building a matched approach rather than selecting each axle in isolation.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Mercedes-Benz S55 AMG?
A period-style approach for a 2006 Mercedes-Benz S55 AMG starts with preserving its original fitment concept: 245/40R19 in front and 275/35R19 in the rear, both as radials on 19-inch wheels. Keeping the staggered layout intact matters more than chasing a cosmetic look that ignores the car's intended proportions.
Because the available options are blackwall performance radials, the appearance remains consistent with the modern AMG character of the car. Owners pursuing a highly exact presentation should also compare wheel design, ride height, and any prior modifications, since those details affect the finished look just as much as the tire brand.
Does correct tire fitment matter for a 2006 Mercedes-Benz S55 AMG restoration?
Correct tire fitment matters on a 2006 Mercedes-Benz S55 AMG restoration because the car relies on a staggered front-and-rear setup rather than a single universal size. Using 245/40R19 in front and 275/35R19 in the rear helps preserve the stance and visual balance associated with this AMG sedan.
Appearance is only one part of the equation. Proper sizing also affects how the car sits on its wheels and whether the finished restoration feels coherent, so it is smart to verify wheel widths, suspension condition, and any non-original changes before finalizing a tire choice for a restoration-oriented build.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Mercedes-Benz S55 AMG?
Yes, modifications can affect tire fitment on a 2006 Mercedes-Benz S55 AMG, especially because the car already uses a staggered 19-inch setup. Aftermarket wheels, altered wheel widths, suspension changes, or ride-height adjustments can change how a 245/40R19 front or 275/35R19 rear tire sits in the wheelwell.
That makes it important to inspect the actual wheel and chassis setup before replacing tires by size alone. Clearance at full steering lock, fender space, and the relationship between tire width and wheel width are all worth checking if the car no longer sits exactly as it did from the factory.
What should I inspect before driving a 2006 Mercedes-Benz S55 AMG on new tires?
Before driving a 2006 Mercedes-Benz S55 AMG on new tires, inspect the wheels for the correct front and rear sizes, confirm tire pressure, and look over the suspension and alignment condition. It also helps to make sure the front 245/40R19 and rear 275/35R19 tires were mounted in the proper positions.
A quick road-use check should also include sidewall condition, valve stems, and any signs of rubbing once the car is back on the ground. On a powerful, heavy performance sedan like the S55 AMG, small fitment or pressure issues tend to show up quickly, so an early recheck after installation is worthwhile.
How should tires on a 2006 Mercedes-Benz S55 AMG be maintained?
Tires on a 2006 Mercedes-Benz S55 AMG should be maintained with regular pressure checks, visual inspection for cuts or bulges, and periodic review of tread wear across both axles. Because the car uses different front and rear sizes, it is especially important to monitor each axle separately rather than assuming wear patterns will match.
Storage and mileage habits matter too, particularly on lower-use examples that may spend long periods parked. Keeping the car away from prolonged heat, sunlight, and ozone sources helps tire condition, and any sign of unusual wear should prompt a check of alignment, suspension condition, and wheel setup before further road use.
