The 2008 Mercedes-Benz S600 sits at the top of the W221 flagship sedan range, combining long-wheelbase luxury with the kind of effortless V12 character buyers expect from an S-Class of this era. Tire fitment on this car is not a one-size decision, because the standard setup uses 18-inch front and rear sizes while the Sport Package moves to a staggered 19-inch arrangement. All four fitments are modern metric radial sizes, so the real choice is confirming whether the car is standard or Sport Package and then comparing available brands, series, and sidewall treatments. That matters for appearance, wheel compatibility, and how the car will actually be used on the road.
Which Tire Size Is Right for The 2008 Mercedes-Benz S600
The 2008 Mercedes-Benz S600 uses four tire sizes across two staggered front-and-rear setups. Standard cars use 18-inch tires, while the Sport Package uses 19-inch tires, so the first step is confirming both the package and the wheel diameter on the car before choosing a tire. Once that is settled, the decision shifts to front versus rear sizing and the available product styles within each fitment.
A 255/45R18 tire uses a 255-millimeter section width, a 45-series profile, radial construction, and an 18-inch rim. On the 2008 Mercedes-Benz S600, this size serves the front position in the standard 18-inch setup and reflects the modern staggered fitment used on high-end performance luxury sedans. Available choices include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, raised white letter, and Redline sidewall treatments plus several series options. This size is the one to evaluate when the car has standard 18-inch front wheels and the owner wants to compare appearance and tire character within that fitment.
A 275/45R18 tire is a wider metric radial that combines a 275-millimeter section width with a 45-series profile on an 18-inch rim. On the 2008 Mercedes-Benz S600, this is the rear size for the standard staggered 18-inch arrangement, so it should be matched to the correct rear wheel rather than treated as a universal four-corner fitment. The available product selection here is more specialized, with a Blackwall M&H Racemaster Drag Radial offering a very different character than the front-size street-oriented assortment. This size deserves close attention when confirming rear-wheel width and intended use on a standard-wheel car.
A 255/40R19 tire carries a 255-millimeter section width, a lower 40-series profile, radial construction, and a 19-inch rim diameter. On the 2008 Mercedes-Benz S600, this size is used at the front on cars equipped with the Sport Package, giving the car a lower-profile 19-inch front fitment than the standard setup. Product choices include BFGoodrich and Pro-Trac offerings in multiple series, with Blackwall, raised white letter, and Redline sidewall presentations. This is the front size to focus on when the car has Sport Package wheels and the buyer is balancing modern tire selection with the desired visual style.
A 275/40R19 tire pairs a 275-millimeter section width with a 40-series profile in radial construction for a 19-inch rim. On the 2008 Mercedes-Benz S600, it serves as the rear size for the Sport Package staggered setup, making it the companion fitment to the 255/40R19 front rather than a stand-alone choice. BFGoodrich and Nitto options are available here, primarily in Blackwall form and across several performance-oriented tire series. This size matters most when confirming a genuine 19-inch rear-wheel setup and comparing rear tire specifications that suit the car's package and intended driving use.
Sub-model fitment on the 2008 Mercedes-Benz S600 is tied directly to wheel package and axle position. Standard cars and Sport Package cars use different front and rear sizes, so confirming both the package and whether you are selecting a front or rear tire is essential before moving forward.

2008 Mercedes-Benz S600 Base Front
The Base Front position uses the standard 18-inch front fitment rather than the lower-profile Sport Package setup. That makes front-wheel diameter confirmation especially important before comparing the available tire series, sidewall styles, and brand choices in this size.
The Base Rear position uses the wider rear tire in the standard 18-inch staggered arrangement. Rear selection should focus on the actual rear wheel setup and intended use, since this fitment is separate from the front and has a more specialized product offering.
The Sport Package Front position moves to a 19-inch front tire with a lower-profile metric radial size. That means the buyer should confirm the car still has its 19-inch Sport Package wheels before comparing Blackwall, raised white letter, or Redline options in this fitment.
The Sport Package Rear position uses the wider 19-inch rear tire that completes the staggered sport setup. Tire choice here should be made alongside the matching front size and after checking rear wheel width, since this fitment is specific to the Sport Package rear axle.
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.

These FAQs focus on the fitment details that matter before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 2008 Mercedes-Benz S600?
The 2008 Mercedes-Benz S600 uses a staggered tire setup, so front and rear sizes are different. Standard cars use 255/45R18 in front and 275/45R18 in the rear, while S600 models with the Sport Package use 255/40R19 in front and 275/40R19 in the rear.
The key step is identifying whether the car has the standard 18-inch setup or the 19-inch Sport Package setup before buying tires. Front and rear sizes should also be matched to their proper wheel positions, and any car with replacement wheels should have its actual wheel diameter and width checked before a new set is chosen.
What size rim does a 2008 Mercedes-Benz S600 use?
A 2008 Mercedes-Benz S600 uses either 18-inch or 19-inch rims, depending on the wheel package. The standard staggered setup uses 18-inch rims front and rear, while the Sport Package uses 19-inch rims front and rear with lower-profile tire sizes.
Rim diameter should be confirmed before tire selection because the S600 uses both 18-inch and 19-inch fitments within the same model year. Since the car also uses different front and rear sizes, it helps to verify the wheel size at each axle and confirm that no aftermarket wheel change has altered the original setup.
Why does the 2008 Mercedes-Benz S600 have more than one tire size?
The 2008 Mercedes-Benz S600 has more than one tire size because it uses staggered front-and-rear fitment and was offered with more than one wheel package. Standard cars use one pair of 18-inch sizes, while Sport Package cars use a different pair of 19-inch sizes.
That means tire selection starts with the exact wheel package on the car, not just the year and model name. A buyer should also separate front and rear fitment carefully, since the wider rear size is not meant to be treated as the front size, and the 18-inch and 19-inch setups are not interchangeable without wheel changes.
Choosing the Right Tire
What should I consider when choosing a 2008 Mercedes-Benz S600 tire?
Start by confirming whether the car uses the standard 18-inch setup or the 19-inch Sport Package setup, then match the correct front and rear sizes. From there, compare radial construction details such as tire series, sidewall style, rim-width compatibility where stated, and load information when it is available.
The available choices vary noticeably by size. The 255 front sizes offer the broadest range of appearance options, including Blackwall, raised white letter, and Redline treatments, while some rear fitments are more specialized. That makes it useful to think about how the S600 will be used, how closely the owner wants to control visual presentation, and whether the wheels remain original.
What sidewall styles are available for 2008 Mercedes-Benz S600 tires?
Sidewall styles for the 2008 Mercedes-Benz S600 include Blackwall across all four sizes, with raised white letter and Redline options appearing in the 255 front fitments. Those added appearance choices are available in both the 18-inch standard front size and the 19-inch Sport Package front size.
That means sidewall choice depends partly on which axle and wheel package you are shopping for. Buyers looking for a cleaner modern look may focus on Blackwall options, while those wanting a stronger visual accent may prefer raised white letter or Redline where available. The rear size should still be selected first for fitment, then narrowed by appearance if multiple options exist.
What brands offer tires for the 2008 Mercedes-Benz S600?
Tire choices for the 2008 Mercedes-Benz S600 include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on the size. BFGoodrich appears across several 18-inch and 19-inch fitments, Nitto appears in select front and rear sizes, Pro-Trac covers the 255 front sizes, and M&H Racemaster appears in the 275/45R18 rear fitment.
Brand choice should come after the fitment is narrowed to the correct wheel package and axle position. Once the size is confirmed, compare each brand's available series, sidewall presentation, rim-width specification where shown, and any published load information. That approach keeps the process centered on the actual S600 setup rather than choosing a tire by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Mercedes-Benz S600?
A period-style approach for a 2008 Mercedes-Benz S600 starts with keeping the correct staggered size and wheel-package layout in place. That means using the standard 18-inch front and rear sizes on a standard car or the 19-inch front and rear sizes on a Sport Package car, then selecting a radial tire that suits the car's visual tone.
Appearance comes down to how understated or expressive the finished car should look. Blackwall tires maintain the most restrained presentation, while raised white letter or Redline options in the 255 front sizes create a more customized look. Buyers pursuing strict originality should compare the car against marque-specific references before settling on a sidewall treatment.
How does tire construction affect the appearance of a restored 2008 Mercedes-Benz S600?
On a 2008 Mercedes-Benz S600, construction does not create a bias-ply-versus-radial appearance decision because the primary fitments are all radial. The visual difference comes more from wheel diameter, tire profile, and sidewall treatment than from switching between construction types within the proper fitment family.
An 18-inch standard setup presents differently than the lower-profile 19-inch Sport Package arrangement, so the restored look should begin with the wheel package already on the car. After that, sidewall style becomes the main appearance choice, especially in the 255 front sizes where Blackwall, raised white letter, and Redline options are available.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mercedes-Benz S600?
Yes. Modifications can affect tire fitment on a 2008 Mercedes-Benz S600, especially because the car already uses staggered sizing and two different rim diameters depending on package. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body-clearance changes can all alter how a tire sits and clears the car.
A modified S600 should be checked at all four corners before new tires are selected. Confirm the actual wheel diameter and width, make sure the front and rear sizes still match the wheel positions, and inspect clearance at full steering lock and normal suspension travel. That is particularly important when replacing only two tires on a staggered setup.
What should I inspect before driving a 2008 Mercedes-Benz S600 on new tires?
Before driving a 2008 Mercedes-Benz S600 on new tires, inspect wheel condition, valve stems, and the mounting direction and placement of each tire. The car's staggered layout makes it especially important to confirm that the correct front and rear sizes were installed on the proper 18-inch or 19-inch wheels.
A short follow-up inspection after the first miles is worthwhile on a large luxury sedan like the S600. Check inflation pressure, look for any sign of rubbing, and pay attention to vibration, pull, or uneven stance that could point to wheel or installation issues. Any car with replacement wheels should also have lug hardware and wheel seating reviewed carefully.
How should tires on a 2008 Mercedes-Benz S600 be maintained?
Tires on a 2008 Mercedes-Benz S600 should be maintained with regular pressure checks, visual inspections, and routine monitoring for uneven wear, cuts, bulges, or sidewall cracking. Because the car uses staggered fitment, maintenance begins with keeping the correct size on each axle and paying attention to condition at both the front and rear.
Collector or low-mileage use can hide age-related problems even when tread still looks good. The car should be inspected before longer drives, and stored vehicles benefit from protection against prolonged sun, heat, moisture, and ozone exposure. Any loss of air, unusual vibration, or visible damage deserves attention before the S600 is put back into regular road use.
