2013 Mercedes-Benz S550 Tires

The 2013 Mercedes-Benz S550 uses several radial tire sizes depending on configuration. Base and 4Matic models use 255/45R18, while Sport Package cars use staggered sizes with 255/40R19 front and 275/40R19 rear, or 255/35R20 front and 275/35R20 rear.

That means the right answer starts with confirming whether the car is standard or Sport Package, and then checking whether it wears 19-inch or 20-inch wheels. On Sport models, front and rear sizes are different, so replacement should be matched by axle position rather than ordered as one universal four-corner size.

A 2013 Mercedes-Benz S550 appears on 18-inch, 19-inch, or 20-inch wheels depending on the configuration. The standard Base and 4Matic setup uses 18-inch rims with 255/45R18 tires, while Sport Package versions use either 19-inch or 20-inch staggered wheel and tire combinations.

Wheel diameter is the first fitment checkpoint on this car because the tire sizes are tied directly to those rim sizes. It also helps to confirm wheel width before final selection, especially on Sport Package tires, since some available products carry specific rim-width ranges that should match the wheels already installed.

The 2013 Mercedes-Benz S550 has more than one tire size because different sub-models use different wheel packages. Standard Base and 4Matic versions use a single 255/45R18 size, while Sport Package versions use staggered front-and-rear combinations in either 19-inch or 20-inch fitments.

That difference matters because a Sport Package S550 is not set up like the standard car. Front and rear tires must be chosen by position, and the correct wheel diameter has to be verified first. A quick check of the existing tire sidewall or wheel size is often the most reliable way to avoid mixing the wrong sizes.

Start with the exact size and wheel setup on the car, because the 2013 Mercedes-Benz S550 can use a standard 18-inch size or staggered 19-inch or 20-inch Sport Package sizes. After size is settled, compare radial tire series, sidewall style, rim-width compatibility, and any load information shown for the tire.

A standard S550 owner may be choosing mainly between brand and appearance options, while a Sport Package owner also needs to keep front and rear sizing straight. Matching the tire to the car's actual wheel diameter, axle position, and intended driving use is more important than choosing by appearance alone.

Sidewall choice depends on the size, but the 2013 Mercedes-Benz S550 has more than just plain Blackwall options in several fitments. Blackwall appears across many BFGoodrich and Nitto products, while selected Pro-Trac Street Pro III tires are also available with RWL and Redline sidewall treatments.

That gives the S550 owner some flexibility in appearance, especially if the goal is a more custom or enthusiast look rather than a purely understated presentation. The key is to make the sidewall choice only after confirming the exact tire size, since style options can vary between the 18-inch, 19-inch, and 20-inch fitments.

Tires for the 2013 Mercedes-Benz S550 are available from BFGoodrich, Nitto, and Pro-Trac across the supported radial sizes. Depending on the exact fitment, the selection includes several BFGoodrich g-Force series, Nitto NT555 G2 applications, and Pro-Trac Street Pro III options in selected sizes.

Brand choice is only one part of the decision on this car. It still makes sense to compare the specific size required, the wheel diameter involved, the sidewall style offered, and any rim-width or load details that matter to the wheel and driving setup already on the S550.

A period-style 2013 Mercedes-Benz S550 still starts with the correct original-type fitment pattern for the car's configuration. That means 255/45R18 on standard Base or 4Matic models, or the proper staggered 19-inch or 20-inch front-and-rear sizes on Sport Package versions.

Appearance then comes down to how closely the tire presentation suits the car's character. Blackwall gives the most restrained luxury-sedan look, while RWL or Redline creates a more customized visual statement in sizes where those options exist. For a highly detail-focused preservation project, vehicle-specific historical references are worth consulting.

On the 2013 Mercedes-Benz S550, tire construction is straightforward because the primary fitments are radial. The bigger appearance difference comes from profile, wheel diameter, and sidewall treatment, especially when comparing the standard 18-inch setup to the lower-profile 19-inch or 20-inch Sport Package combinations.

A standard-wheel S550 tends to present a fuller sidewall look, while Sport Package sizing gives the car a more aggressive stance. Sidewall style changes the visual effect further, with Blackwall keeping things understated and RWL or Redline shifting the car toward a more personalized presentation where those options are offered.

Yes. A 2013 Mercedes-Benz S550 can be affected by aftermarket wheels, altered wheel widths, suspension changes, lowering, or body modifications just like any other vehicle. Those changes matter even more on Sport Package cars because the factory-style setup already uses staggered front-and-rear tire sizes on larger wheel diameters.

A modified S550 should be checked for wheel diameter, wheel width, and tire clearance at the front and rear before choosing replacements. Even when the tire size looks familiar, the actual wheel and suspension setup may no longer match the original fitment pattern, so measuring what is on the car is the safest next step.

Before driving a 2013 Mercedes-Benz S550 on new tires, inspect the wheel condition, confirm the front and rear sizes match the car's configuration, and make sure the tires are seated and inflated properly. It also helps to check for any rubbing risk at full steering lock and through normal suspension movement.

A road-ready inspection should include looking over the suspension and alignment condition as well, since worn components can affect how a large sedan uses its tires. On staggered Sport Package cars, confirm the front pair and rear pair have been installed in the proper positions before putting serious miles on the car.

Tires on a 2013 Mercedes-Benz S550 should be inspected regularly, not just when tread wear becomes obvious. A quick visual check for air loss, uneven wear, sidewall damage, cuts, or bulges is worthwhile before longer drives, and a closer inspection should be part of normal maintenance intervals.

That habit is especially important on a heavy luxury sedan with multiple possible wheel and tire combinations. Sport Package cars also benefit from routine front-to-rear visual comparison, since the staggered setup means the tires are different sizes and can show different wear patterns that point to alignment or suspension concerns.
