The 2006 Mercedes-Benz S500 belongs to the W220 generation, a full-size luxury sedan shaped around quiet high-speed touring, technology, and long-wheelbase composure. Buyers looking at one today are often balancing original character with practical road use, especially on cars that may have seen wheel, suspension, or appearance changes over time. Tire fitment on the 2006 Mercedes-Benz S500 centers on radial construction, with 225/55R17 on standard applications and 18-inch sport-package sizing in 245/45R18 front and 265/40R18 rear form. Available choices range from blackwall performance-oriented radials to Silvertown Radial whitewall and redline styles. The key is matching the exact sub-model and wheel setup before choosing appearance or performance character.
Which Tire Size Is Right for The 2006 Mercedes-Benz S500
Three primary tire sizes apply to the 2006 Mercedes-Benz S500, and the correct choice depends on the exact sub-model and wheel package. Standard cars and 4Matic models use a 17-inch radial, while sport-package fitments move to 18-inch sizes, including a staggered front and rear setup on the rear-wheel-drive sport model. Confirming both the sub-model and actual wheel diameter should come before comparing brands, sidewall style, or tire series.
225/55R17 is a metric radial size: 225 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2006 Mercedes-Benz S500, this size serves the standard 17-inch setup rather than the sport-package applications. Available choices include BFGoodrich performance-oriented blackwall tires as well as Silvertown Radial options in wide whitewall and redline form. It is the size to evaluate when maintaining the standard-wheel look or when a restoration-inspired sidewall treatment is part of the plan.
Fit(s): 4Matic w/Sport Pkg. and w/Sport Pkg. Front
Construction: Radial|Rim: 18 in
245/45R18 is a metric radial size with a 245-millimeter nominal width, a 45-series profile, radial construction, and an 18-inch rim diameter. This size is used on sport-package front fitments and also appears on the 4Matic sport-package application, so it belongs to specific 18-inch configurations rather than every S500. Product choices here focus on blackwall radials from BFGoodrich and Nitto across several performance-oriented series. It is the right size to investigate when the car carries the sport wheel package and calls for a front or all-around 245/45R18 fitment.
265/40R18 uses the same metric radial format, with a wider 265-millimeter nominal section and a lower 40-series profile on an 18-inch wheel. On the 2006 Mercedes-Benz S500, this is the rear size for the sport-package staggered setup, so it works as part of a matched front-and-rear arrangement rather than as a universal S500 fitment. The available choice in this size is a BFGoodrich g-Force Phenom T/A blackwall radial. This size matters most when keeping the intended rear sport stance and confirming that the car still has the correct 18-inch rear wheels.
Sub-model fitment on the 2006 Mercedes-Benz S500 is not one-size-fits-all. Standard and 4Matic applications share the 17-inch setup, while sport-package versions move to 18-inch sizing, making the exact sub-model and wheel arrangement the first thing to verify before selecting tires.

2006 Mercedes-Benz S500 4Matic
The 2006 Mercedes-Benz S500 4Matic uses the standard 225/55R17 radial fitment rather than the sport-package 18-inch setup. That keeps tire selection centered on the correct 17-inch size, with the main choice becoming blackwall performance styling versus more traditional wide whitewall or redline presentation.
The 2006 Mercedes-Benz S500 4Matic w/Sport Pkg. uses 245/45R18 radial tires. This makes wheel confirmation especially important, then the decision shifts to comparing available blackwall tire series and their rim-width suitability within the correct 18-inch fitment.
The 2006 Mercedes-Benz S500 Base uses the same 225/55R17 radial size as the standard all-wheel-drive version. Buyers with this sub-model can focus less on fitment variation and more on choosing the tire character they want, whether that means a contemporary blackwall or a more distinctive restoration-oriented sidewall style.
The front fitment for the 2006 Mercedes-Benz S500 w/Sport Pkg. is 245/45R18 radial. That front-specific size should be matched carefully within a staggered setup, especially if the car has had wheel changes or if the goal is to preserve the intended sport-package tire relationship front to rear.
The rear fitment for the 2006 Mercedes-Benz S500 w/Sport Pkg. is 265/40R18 radial. Tire selection here is tied to the rear half of the staggered sport-package arrangement, so the practical focus is confirming rear wheel width and maintaining the proper front-to-rear size pairing.
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 S500?
The 2006 Mercedes-Benz S500 uses three possible tire sizes: 225/55R17, 245/45R18, and 265/40R18. Standard S500 Base and S500 4Matic models use 225/55R17, the S500 4Matic w/Sport Pkg. uses 245/45R18, and the rear-wheel-drive S500 w/Sport Pkg. uses a staggered 18-inch setup with 245/45R18 in front and 265/40R18 in the rear.
The important first step is identifying the exact sub-model and then confirming the actual wheels on the car. Many S-Class sedans have seen wheel swaps over the years, so the correct answer comes from matching the sub-model and measured rim diameter before choosing a tire series or sidewall style.
What size rim does a 2006 Mercedes-Benz S500 use?
A 2006 Mercedes-Benz S500 uses either 17-inch or 18-inch rims, depending on configuration. The 225/55R17 fitment uses a 17-inch wheel, while the 245/45R18 and 265/40R18 sport-package sizes use 18-inch wheels. On the staggered sport-package setup, the front and rear both share the 18-inch diameter even though the tire widths differ.
Rim diameter needs to be confirmed before anything else because a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is equally true. Once diameter is settled, check wheel width as well, especially on sport-package cars where front and rear fitments may not be the same.
Do all 2006 Mercedes-Benz S500 sub-models use the same tire size?
No, the 2006 Mercedes-Benz S500 does not use one tire size across every sub-model. Base and 4Matic versions share 225/55R17, the 4Matic sport-package version uses 245/45R18, and the rear-wheel-drive sport-package car uses a staggered combination of 245/45R18 front and 265/40R18 rear.
That variation means the badge on the trunk is only part of the story. A quick check of the sub-model, wheel diameter, and whether the car has a staggered sport setup will keep a buyer from choosing the wrong tire width or ordering a square set for a car that needs separate front and rear sizes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Mercedes-Benz S500?
Start with the exact fitment: 225/55R17 for standard models, 245/45R18 for certain sport-package applications, and 265/40R18 for the rear of the staggered sport setup. From there, compare construction, rim-width compatibility, load figures where stated, and the intended character of the tire, whether that is a blackwall performance-style radial or a more appearance-driven Silvertown Radial.
The right choice depends on how the car is used and how original-looking it needs to be. A touring-oriented owner may focus on preserving the proper size and wheel relationship, while an appearance-minded buyer may care more about sidewall presentation on a standard 17-inch S500.
What sidewall styles are available for 2006 Mercedes-Benz S500 tires?
Sidewall choice varies by size. Blackwall tires are available across all three S500 fitments, while 225/55R17 also offers more distinctive treatments in BFGoodrich Silvertown Radial form, including wide whitewall and redline versions. Those options give the standard-wheel S500 a broader appearance range than the 18-inch sport-package sizes.
Sidewall style affects the visual character of the car more than fitment itself, but it still needs to be chosen within the correct tire size. Buyers interested in a more customized or restoration-inspired look should confirm they are working with the 17-inch 225/55R17 application before focusing on whitewall or redline styling.
What brands offer tires for the 2006 Mercedes-Benz S500?
BFGoodrich appears across all three primary S500 sizes, covering series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Silvertown Radial. Nitto is also available in 245/45R18 with the NT555 G2, which gives the 18-inch front or sport-package fitment an additional brand choice.
Brand comparison should come after size and wheel setup are confirmed. On this vehicle, the available brands also track with the type of presentation: BFGoodrich covers both performance-style blackwalls and vintage-inspired sidewall treatments, while the Nitto option stays focused on a blackwall sport-oriented look.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Mercedes-Benz S500?
A period-style approach starts with keeping the correct original fitment pattern for the exact sub-model, whether that is 225/55R17 on a standard S500 or the 18-inch sport-package sizing. Among the available options, the 225/55R17 BFGoodrich Silvertown Radial choices in wide whitewall or redline create the most appearance-driven departure from a plain blackwall presentation.
For a more restrained look, a blackwall radial in the correct size usually suits the W220’s original luxury-sedan character better than an obviously custom sidewall. Buyers chasing exact historical presentation should compare tire appearance against period Mercedes-Benz sales materials, dealer literature, or marque-specific restoration references before deciding.
How does tire construction affect the appearance of a restored 2006 Mercedes-Benz S500?
All primary fitments for the 2006 Mercedes-Benz S500 are radial, so construction choice here is less about bias-ply versus radial appearance and more about the visual style within radial offerings. Blackwall tires maintain a modern luxury-sedan look, while the Silvertown Radial whitewall and redline versions on 225/55R17 create a more customized or nostalgic presentation.
Appearance also depends on wheel diameter and whether the car uses the standard or sport-package setup. A restored S500 will usually look most cohesive when the tire profile, sidewall treatment, and wheel package all match the car’s intended theme rather than mixing standard and sport-package visual cues.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Mercedes-Benz S500?
Yes, modifications can change tire fitment on a 2006 Mercedes-Benz S500. Aftermarket wheels, altered offsets, suspension lowering, and non-original sport-package conversions can all affect which size works cleanly, especially on cars moving between 17-inch and 18-inch setups or on models using the staggered 245/45R18 front and 265/40R18 rear arrangement.
A modified S500 should be checked at the car, not just by model name. Measure wheel diameter and width, look for clearance at the fender and suspension, and confirm that front and rear tires match the actual wheel layout before selecting replacements in any of the factory S500 sizes.
What should I inspect before driving a 2006 Mercedes-Benz S500 on new tires?
Before road use, inspect wheel condition, valve stems, tire pressure, and basic clearance at full steering lock and normal ride height. It is also smart to verify that the tires match the vehicle’s actual front and rear wheel setup, especially on a sport-package S500 where the rear size differs from the front.
A car that has spent long periods parked deserves extra attention. Look over suspension wear, signs of rubbing, and any old alignment issues that may have affected the previous tires, because a fresh set can only perform as intended when the wheels, chassis, and tire sizing are all working together properly.
How often should tires on a 2006 Mercedes-Benz S500 be inspected?
Tires on a 2006 Mercedes-Benz S500 should be inspected regularly, not just when tread looks low. A visual check for air loss, cracking, bulges, cuts, and uneven wear is a sensible routine on any older luxury sedan, and it matters even more on collector-owned or low-mileage cars that may sit for extended periods.
The inspection routine should also include pressure checks and a quick look at age-related condition, since stored cars can develop problems without accumulating many miles. Sport-package cars deserve added attention because staggered front and rear sizes make it easier to overlook a mismatch after past service or wheel changes.
