2013 Mercedes-Benz S400 Tires

The 2013 Mercedes-Benz S400 uses several tire sizes rather than one universal fitment. The standard S400 Hybrid uses 255/45R18, while Sport Package applications use staggered front and rear sizes: either 255/40R19 front with 275/40R19 rear, or 255/35R20 front with 275/35R20 rear.

That means the correct choice depends on the exact wheel package and, on Sport Package cars, the axle position. Checking only the model year and name is not enough. Confirm the wheel diameter on the car and whether you are replacing front tires, rear tires, or a complete matched set before selecting a size.

A 2013 Mercedes-Benz S400 can use 18-inch, 19-inch, or 20-inch rims depending on configuration. The standard S400 Hybrid uses an 18-inch fitment, while Sport Package setups use either 19-inch or 20-inch wheel diameters with different front and rear tire sizes.

Wheel diameter is the first thing to verify because it determines which tire size family even belongs on the car. A quick check of the sidewall or the wheel itself usually confirms that. On Sport Package cars, also confirm whether the vehicle has a staggered setup so the front and rear tire sizes are matched to the correct rims.

The 2013 Mercedes-Benz S400 has more than one tire size because the standard Hybrid and the Sport Package versions do not share the same wheel and tire setup. The standard car uses a square 255/45R18 arrangement, while Sport Package versions use wider rear tires and come in either 19-inch or 20-inch staggered combinations.

That variation means tire replacement starts with identifying the actual setup on the vehicle, not just the model name. Cars that have had wheel changes over time deserve an extra look at the current front and rear sizes. Replacing a staggered arrangement with the wrong pairing can upset both appearance and basic fitment.

Start with the exact tire size and axle position, because the 2013 Mercedes-Benz S400 may be a standard 18-inch Hybrid setup or a staggered 19-inch or 20-inch Sport Package arrangement. Every primary fitment here is radial, so the main comparison points become size accuracy, wheel compatibility, tire series, sidewall style, and any published load figures.

After the size is confirmed, think about how the car is used. A square 18-inch setup can be approached differently than a sport staggered combination. Some owners will want a straightforward blackwall performance radial, while others may prefer a more distinctive sidewall treatment. Matching the tire to the car’s current wheels is just as important as picking a preferred look.

Sidewall choices for the 2013 Mercedes-Benz S400 include blackwall on many BFGoodrich and Nitto radial options, plus raised white letter and redline versions in the Pro-Trac Street Pro III line for several applicable sizes. The exact sidewall styles available depend on the specific tire size being replaced.

That gives the S400 owner a real appearance decision once the correct fitment is pinned down. Blackwall keeps the look understated and contemporary, while raised white letter or redline adds more visual emphasis. Since availability changes by size, confirm the front or rear dimension first and then compare sidewall treatments within that exact fitment.

Tires for the 2013 Mercedes-Benz S400 are available from BFGoodrich, Nitto, and Pro-Trac across the applicable radial sizes. Depending on the size, choices include BFGoodrich g-Force series products, Nitto NT555 G2 options, and Pro-Trac Street Pro III tires with multiple sidewall treatments.

The practical difference is not simply brand name, but how each option lines up with the size, wheel package, and presentation you want. Some products also publish rim-width ranges or load-capacity figures, which can help narrow the field. Once the correct size is confirmed, compare those details instead of choosing only by brand recognition.

A period-style approach on a 2013 Mercedes-Benz S400 starts with keeping the correct wheel diameter and fitment layout already on the car. That means 255/45R18 for the standard Hybrid, or the proper staggered 19-inch or 20-inch sport sizes for Sport Package cars, before narrowing the choice to a suitable radial tire series.

Appearance then comes down to how subtle or expressive you want the finished look to be. Blackwall tires keep the presentation closest to a restrained luxury-sedan style, while some sizes also allow raised white letter or redline alternatives. Preserving the proper front-to-rear sizing relationship is usually more important than adding a decorative sidewall treatment.

On the 2013 Mercedes-Benz S400, the primary fitments are all radial, so the construction question is less about bias-ply versus radial appearance and more about choosing the right radial style within the correct size. The visual difference usually comes from sidewall treatment, overall stance, and whether the car keeps its intended square or staggered layout.

That makes correct sizing a major part of the finished appearance. A standard Hybrid with 18-inch fitment presents differently from a Sport Package car with wider rear tires on 19-inch or 20-inch wheels. Owners focused on a clean restoration-style result should verify the actual wheel package first, then compare sidewall style and tire series second.

Yes. Modifications can change tire fitment on a 2013 Mercedes-Benz S400, especially if the car has aftermarket wheels, altered wheel widths, suspension changes, or a different front-to-rear setup than it originally carried. Those changes matter more on Sport Package cars because the fitment is already staggered and tied closely to wheel diameter.

Any time the wheels or suspension have been changed, compare the current rim diameter and tire size at each axle before ordering replacements. Clearance at the fender, inner wheelhouse, and steering range should also be checked. A tire that matches the model name on paper still needs to suit the actual wheel and chassis setup on the car.

Before driving a 2013 Mercedes-Benz S400 on new tires, confirm that the correct sizes were installed in the correct positions, especially on Sport Package cars with wider rear tires. Then inspect inflation pressure, wheel condition, valve stems, and overall clearance so the new tires sit and operate properly on the car.

A short visual check after installation can prevent common issues. Look for any contact near suspension components, fender liners, or body edges, and make sure the steering turns freely lock to lock on front tires. After the first miles, recheck pressure and inspect for any uneven seating or air loss so the setup is ready for normal road use.

Tires on a 2013 Mercedes-Benz S400 should be maintained with regular pressure checks, routine inspection for cuts, bulges, cracking, and uneven wear, and close attention to front-versus-rear placement on staggered Sport Package setups. Because the S400 may use different front and rear sizes, tire service should always begin with confirming position and size.

Low-use luxury cars can age their tires before they wear them out, so storage conditions matter as much as mileage. Keep the vehicle away from prolonged sunlight, excess heat, and ozone sources when possible, and inspect the sidewalls closely before longer drives. Staying ahead of age and condition issues is especially important on a heavy sedan with multiple wheel-package options.
