2013 Mercedes-Benz S350 Tires

The 2013 Mercedes-Benz S350 uses 255/45R18, 255/40R19, 255/35R20, and 275/35R20 radial tire sizes. The 18-inch and 19-inch sizes apply to the S350 Bluetec 4Matic, while the 20-inch sizes are used in a staggered arrangement with 255/35R20 at the front and 275/35R20 at the rear.

That means the first job is identifying the actual wheel setup on the car rather than choosing by model name alone. A car fitted with 20-inch wheels needs the front and rear sizes kept in their proper positions, while an 18-inch or 19-inch car should stay with the correct single-size fitment for that wheel diameter.

A 2013 Mercedes-Benz S350 appears with 18-inch, 19-inch, and 20-inch rim diameters depending on the configuration. The 255/45R18 fits an 18-inch rim, the 255/40R19 fits a 19-inch rim, and the staggered setup uses 255/35R20 front and 275/35R20 rear on 20-inch rims.

Rim diameter should always be confirmed from the wheel itself before ordering tires, especially on a luxury car that may have been fitted with different factory-style or aftermarket wheels over time. Once diameter is verified, wheel width becomes the next useful check, particularly on the wider 20-inch rear fitment.

The 2013 Mercedes-Benz S350 has more than one tire size because it was fitted with different wheel packages, including 18-inch and 19-inch single-size setups as well as a staggered 20-inch arrangement. In the staggered configuration, the front and rear tires are intentionally different, using 255/35R20 in front and 275/35R20 in back.

That makes the exact wheel arrangement more important than assuming every S350 uses the same tire. Looking at the sidewall size markings or measuring wheel diameter is the safest way to confirm what belongs on the car, and it also helps avoid mixing front and rear sizes incorrectly on a staggered setup.

Start with the correct size and wheel diameter, because the 2013 Mercedes-Benz S350 can use 18-inch, 19-inch, or staggered 20-inch radial fitments. From there, compare the tire series available in that exact size, along with sidewall style, rim-width specification, weight, and any stated load capacity figures that matter to the way the car is used.

A buyer focused on preserving a more understated modern look may prefer a blackwall, while someone after a more customized presentation may look at raised white letter or redline options. It also helps to match the tire to the vehicle’s actual setup, since a front 20-inch tire and a rear 20-inch tire do not serve the same fitment role.

Tires for the 2013 Mercedes-Benz S350 are available in blackwall, RWL, and redline sidewall styles, depending on size and tire series. Blackwall choices appear across BFGoodrich and Nitto products, while Pro-Trac Street Pro III options add RWL, which can be described as raised white letter, and redline alternatives.

The right sidewall choice depends on how the car is being presented. A blackwall generally suits a more restrained contemporary look, while RWL and redline give the S350 a more customized appearance. Sidewall style should always come after confirming the correct size, since not every treatment appears in every fitment used on this model.

BFGoodrich, Nitto, and Pro-Trac offer tires for the 2013 Mercedes-Benz S350 across its 18-inch, 19-inch, and 20-inch sizes. Depending on the fitment, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.

Choosing among those brands is less about picking a name first and more about matching the product to the exact wheel setup and the look you want. Some sizes include only blackwall choices from one brand group, while others also add RWL or redline options, which can materially change the car’s appearance.

A period-style approach for a 2013 Mercedes-Benz S350 starts with keeping the correct wheel diameter and tire size already associated with the car, whether that is 255/45R18, 255/40R19, or the staggered 20-inch combination. From there, a blackwall radial usually keeps the presentation closest to the restrained luxury appearance many owners want on a modern S-Class sedan.

Appearance goals can still vary, especially on cars that have taken on a more personalized look over time. The most important thing is not to let style override fitment basics, since the S350 uses multiple wheel diameters and, in one configuration, different front and rear tire sizes that need to remain properly matched.

On the 2013 Mercedes-Benz S350, tire construction is straightforward because the primary fitments are radial. That means the appearance difference comes less from choosing between bias-ply and radial construction and more from the tire’s sidewall design, profile, brand character, and whether the car sits on 18-inch, 19-inch, or staggered 20-inch wheels.

A blackwall radial tends to preserve a cleaner, more contemporary luxury-sedan presentation, while raised white letter and redline treatments create a more customized visual statement. Owners working toward a restoration-oriented result should confirm the car’s actual wheel package first, then choose a tire that supports the intended look without changing the fundamental fitment.

Yes, modifications can affect tire fitment on a 2013 Mercedes-Benz S350 even when the tire size looks close to the original setup. Aftermarket wheels can change width or offset, and suspension changes can alter clearance at the fender, inner wheelhouse, or steering components, especially on cars using the staggered 20-inch front-and-rear arrangement.

That makes it important to inspect the actual wheel dimensions and available space before replacing tires on a modified car. A size that belongs on one S350 configuration should not be assumed correct for another, and a wider rear 20-inch tire deserves extra attention when checking wheel width and body clearance.

Before driving a 2013 Mercedes-Benz S350 on new tires, confirm that each tire matches the correct position on the car, especially if it uses staggered 20-inch sizes. It is also smart to check inflation pressure, valve stems, wheel condition, and whether the tires seat properly on the rims without signs of damage or air loss.

A short visual inspection after installation can prevent avoidable problems. Look for sidewall contact, uneven spacing inside the wheel opening, and any sign that a front tire and rear tire have been mixed on a staggered setup. After a brief road test, recheck pressure and make sure the car tracks smoothly without vibration.

Tires on a low-use 2013 Mercedes-Benz S350 should be maintained with regular pressure checks, periodic visual inspections, and attention to age-related condition even if tread wear is minimal. Sidewall cracking, bulges, cuts, and slow air loss matter just as much as remaining tread depth on a luxury car that may spend long periods parked.

Storage habits also make a difference. Keeping the car away from prolonged sunlight, excess heat, and ozone sources can help preserve the tires, while occasional movement helps avoid long-term flat spotting. It is also wise to inspect the staggered front and rear tires individually, since each size has its own wear pattern and replacement role.
