The 2006 Mercedes-Benz S65 AMG sits at the top of the W220 S-Class range, combining full-size luxury sedan presence with the kind of power and speed that made AMG flagships so distinctive in the 2000s. On a car like this, tire fitment is tied as much to chassis balance and high-speed composure as it is to appearance. The 2006 Mercedes-Benz S65 AMG uses a staggered radial setup with 245/40R19 in front and 275/35R19 in the rear, both on 19-inch wheels. Available choices center on blackwall performance-oriented radial tires from BFGoodrich and Nitto across several series. The key is matching the correct front and rear sizes while confirming wheel width, vehicle condition, and any modifications before replacement.
Which Tire Size Is Right for The 2006 Mercedes-Benz S65 AMG
The 2006 Mercedes-Benz S65 AMG uses two primary tire sizes, and the difference is front-to-rear rather than trim-to-trim. Both are radial tires for 19-inch wheels, so the first step is confirming whether you are replacing the front axle tires, the rear axle tires, or a full staggered set while keeping the correct wheel position matched to the right size.
245/40R19 is a metric radial size in which 245 represents nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2006 Mercedes-Benz S65 AMG, this size is used at the front, where proper fitment helps preserve the intended balance of steering response and clearance. Available choices include blackwall radial tires from BFGoodrich in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This is the size to focus on when replacing front tires or building a matched staggered set.
275/35R19 is a metric radial size with a 275-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2006 Mercedes-Benz S65 AMG, this size is used at the rear, giving the car its wider back tire fitment and making rear wheel width especially important during replacement. Product choices include blackwall radial tires from BFGoodrich and Nitto, with series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the correct size to evaluate when replacing rear tires or maintaining the original staggered layout.
Fitment on the 2006 Mercedes-Benz S65 AMG is straightforward in one sense and specific in another, because the covered configuration uses a staggered setup rather than different trim packages. Checking whether the tire is for the front or rear position matters more than anything else before comparing products.

2006 Mercedes-Benz S65 AMG Base Front
The Base Front position uses the narrower of the two radial sizes on a 19-inch wheel, making it the front-axle fitment rather than a universal size for the whole car. Tire selection here centers on choosing the right front-position radial tire series while keeping wheel-width compatibility and matched staggered fitment in mind.
The Base Rear position uses the wider 19-inch radial size, so rear tire replacement should be handled as a distinct fitment choice rather than grouped with the front. Selection usually comes down to choosing among the available rear tire series and confirming the wheel setup remains correct for the wider rear tire.
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 S65 AMG?
The 2006 Mercedes-Benz S65 AMG uses a staggered tire setup with 245/40R19 on the front and 275/35R19 on the rear. Both are radial tire sizes for 19-inch wheels, so this car does not use the same size at all four corners.
That means replacement starts with identifying wheel position first. A front tire and a rear tire are not interchangeable just because they share the same rim diameter. Confirm whether the car still has its original wheel layout, then match the correct size to the correct axle before comparing tire series, load specifications, and brand choices.
What size rim does a 2006 Mercedes-Benz S65 AMG use?
Both primary tire sizes for the 2006 Mercedes-Benz S65 AMG are built for 19-inch wheels. The front size, 245/40R19, and the rear size, 275/35R19, share the same rim diameter even though the tire widths and profiles differ.
Rim diameter is only part of the fitment picture on a staggered setup. Front and rear wheel widths may differ, and the available tires reflect different recommended rim-width ranges by size. Before replacing tires, check the actual wheel dimensions on the car, especially if it has aftermarket wheels or if a previous owner changed the original setup.
Why does the 2006 Mercedes-Benz S65 AMG have more than one tire size?
The 2006 Mercedes-Benz S65 AMG uses more than one tire size because it has a staggered fitment, with one size for the front and a wider size for the rear. In this case, 245/40R19 is used in front and 275/35R19 is used in back.
A staggered layout affects how the car looks, how the tires sit on the wheels, and how replacements should be handled. The practical takeaway is simple: do not assume four matching tires are correct for this application. Check wheel position, confirm the wheel setup on the car, and keep the front and rear sizes properly separated when selecting replacements.
Choosing the Right Tire
What should I consider when choosing a 245/40R19 or 275/35R19 tire for a 2006 Mercedes-Benz S65 AMG?
Start with the correct axle position, since the 2006 Mercedes-Benz S65 AMG uses 245/40R19 in front and 275/35R19 in the rear. From there, compare radial tire series, rim-width compatibility, load figures where stated, and whether you want a matched set from one line or different front and rear selections.
Appearance is straightforward here because the available options are blackwall tires, so the real differences are in sizing suitability and product character. Check the actual wheel widths on the car, especially at the rear, and make sure the chosen tires suit the vehicle's current setup if suspension, wheels, or alignment settings have been changed.
What sidewall styles are available for 2006 Mercedes-Benz S65 AMG tires?
The available tires for the 2006 Mercedes-Benz S65 AMG are blackwall radials in both 245/40R19 and 275/35R19. That keeps the presentation clean and modern, which suits the car's original performance-luxury character without introducing vintage-style sidewall treatments.
Since sidewall style does not vary here, the more useful comparison is between tire series, wheel-width compatibility, and front-versus-rear fitment. Buyers focused on appearance can concentrate on keeping a uniform look across the staggered setup, while buyers focused on function should verify that both axle sizes remain matched correctly to the car's wheel arrangement.
What brands offer tires for the 2006 Mercedes-Benz S65 AMG?
BFGoodrich and Nitto offer tires in the sizes used by the 2006 Mercedes-Benz S65 AMG. BFGoodrich appears in both the front and rear sizes through several g-Force series, while Nitto is available in the rear 275/35R19 size through the NT555 G2 line.
That mix gives you the option to keep the same brand across the staggered setup or compare rear-only alternatives if you are replacing the wider back tires separately. Brand alone should not drive the decision, though. Confirm the correct front and rear sizes, wheel-width suitability, and the kind of road use you expect before narrowing the choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Mercedes-Benz S65 AMG?
Yes. Modifications can change tire fitment on a 2006 Mercedes-Benz S65 AMG even when the tires remain 245/40R19 in front and 275/35R19 in the rear. Aftermarket wheels, altered offsets, suspension changes, or ride-height adjustments can all affect how those sizes sit and clear the body and chassis.
A car with factory-style wheel and suspension dimensions is easier to match than one that has been lowered or re-wheeled. Check actual wheel width, offset, inner clearance, and fender clearance before replacement, especially at the rear. That extra verification matters more on a staggered high-performance sedan than it would on a simple same-size four-corner setup.
What should I inspect before driving a 2006 Mercedes-Benz S65 AMG on new tires?
Inspect the wheel condition, confirm the front and rear sizes are mounted in the correct positions, and check tire pressure before road use. It is also smart to look over the suspension, alignment condition, and brake components so the new tires are not immediately affected by underlying wear or setup problems.
A careful walk-around should include looking for sidewall damage, bead seating issues, rubbing marks, and any sign that the tire is too close to suspension or body components. On a powerful sedan with a staggered setup, a short low-speed test drive followed by a second inspection can reveal clearance or vibration issues before the car is driven harder.
How often should tires on a 2006 Mercedes-Benz S65 AMG be inspected?
Tires on a 2006 Mercedes-Benz S65 AMG should be inspected regularly, not just at installation or seasonal service. Check them before longer drives and make a habit of looking for uneven wear, cracking, cuts, punctures, bulges, and pressure loss, especially since front and rear tires do different jobs on a staggered setup.
Routine inspection is especially important on enthusiast-owned cars that may spend time parked between drives. A vehicle can have good tread depth and still have aging or condition issues that deserve attention. Consistent pressure checks, visual inspection, and prompt correction of alignment or suspension problems help the tires deliver the fitment and road manners the chassis expects.
