The 2016 Mercedes-Benz E400 sits in the later W212 era, blending the composed road manners expected of an E-Class with the stronger character of the coupe, convertible, and sedan body styles. Tire fitment matters here because this model uses three different 18-inch radial sizes depending on whether the car is a sedan or a staggered front-and-rear coupe or convertible setup. That means the real decision is not just size, but also confirming position on the car and then comparing available tire series, brands, and sidewall treatments. A careful match helps preserve the E400’s balanced look, predictable handling, and proper clearance on the wheel package actually installed.
Which Tire Size Is Right for The 2016 Mercedes-Benz E400
The 2016 Mercedes-Benz E400 uses three primary tire sizes, all in radial construction on 18-inch wheels. The key first step is identifying whether the car is a sedan with the same size at all four corners or a coupe or convertible with a staggered setup that uses one size in front and a different size in back. Once that is confirmed, the choice shifts to tire series, brand, sidewall style, and wheel-width compatibility.
Fit(s): 4Matic Coupe Front, Convertible Front, and Coupe Front
Construction: Radial|Rim: 18 in
235/40R18 is a modern metric radial size: 235 denotes nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2016 Mercedes-Benz E400, this size serves the front position on coupe, convertible, and 4Matic coupe applications that use a staggered layout. Available choices include BFGoodrich and Nitto tires in blackwall form across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the right place to focus when the front axle needs to match a staggered 18-inch setup.
Fit(s): 4Matic Coupe Rear, Convertible Rear, and Coupe Rear
Construction: Radial|Rim: 18 in
255/35R18 is also a modern metric radial, with a wider 255-millimeter section width, a 35-series profile, radial construction, and an 18-inch rim diameter. On the 2016 Mercedes-Benz E400, this size is used at the rear of staggered coupe, convertible, and 4Matic coupe fitments rather than across all body styles. Product choices include BFGoodrich and Nitto blackwall tires in several performance-oriented series, giving buyers options within the correct rear size. This is the size to confirm when replacing rear tires on an E400 that does not use the same dimensions front and rear.
245/40R18 follows the same metric radial format, with 245 millimeters of nominal width, a 40-series aspect ratio, radial construction, and fitment on an 18-inch wheel. For the 2016 Mercedes-Benz E400, this is the sedan size, making it the main fitment for both the standard sedan and the 4Matic sedan. The selection range is broader here, with BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac options, mostly in blackwall form but also with redline and raised white letter treatments in Street Pro III. It is the size to evaluate when the car uses a square sedan setup and the owner wants either a contemporary blackwall look or a more distinctive sidewall presentation.
Fitment on the 2016 Mercedes-Benz E400 varies by body style and wheel position rather than following one universal size across the range. Checking the exact sub-model matters because the sedan uses one square setup, while coupe and convertible versions use different front and rear tire sizes.

2016 Mercedes-Benz E400 4Matic Coupe Front
The 2016 Mercedes-Benz E400 4Matic Coupe Front uses the narrower front tire in the staggered coupe setup, making front and rear selection a matched-position decision rather than a single all-around purchase. Tire choice here centers on keeping the correct front size while comparing blackwall radial options across the available performance-oriented series.
The 2016 Mercedes-Benz E400 4Matic Coupe Rear uses the wider rear tire that completes the staggered 18-inch arrangement. Selecting for this position means confirming the rear size specifically and then comparing radial products by brand, tire series, and the wheel-width range that suits the rear wheel.
The 2016 Mercedes-Benz E400 4Matic Sedan uses the same primary tire size at all four corners, which makes replacement more straightforward than the staggered coupe and convertible layout. That leaves the buyer free to focus on radial product differences such as tire series, blackwall versus specialty sidewall styling, and intended road use.
The 2016 Mercedes-Benz E400 Convertible Front uses the front size from the convertible’s staggered arrangement, so front tires should be selected by position rather than by model name alone. The practical goal is maintaining the correct front fitment while choosing among the available blackwall radial series from BFGoodrich and Nitto.
The 2016 Mercedes-Benz E400 Convertible Rear carries the wider rear size used on the staggered convertible setup. Rear replacement should be handled with that position in mind, then narrowed by brand, radial tire series, and wheel compatibility instead of assuming the front and rear use the same dimensions.
The 2016 Mercedes-Benz E400 Coupe Front uses the same front tire size found on the staggered coupe layout, separate from the rear fitment. That makes correct front-position sizing the first step, followed by comparing blackwall radial choices in the available BFGoodrich and Nitto series.
The 2016 Mercedes-Benz E400 Coupe Rear uses the wider rear tire that pairs with the coupe’s front size on a staggered setup. Tire selection for this position should stay centered on the correct rear fitment first, then on series and wheel-width details that suit the rear wheel package.
The 2016 Mercedes-Benz E400 Sedan uses one all-around size instead of the staggered front-and-rear combination found on the coupe and convertible. That simplifies fitment, so the main comparison becomes which radial tire series, brand, and sidewall style best matches the car’s appearance and road use.
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.

Available 18-inch E400 tire choices are all radial, with BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac offerings across several tire series. Most are blackwall, while 245/40R18 also adds redline and raised white letter options for sedan owners who want a more distinctive sidewall look.
These FAQs focus on the exact tire sizes used on the 2016 Mercedes-Benz E400, how fitment changes between sedan and staggered coupe or convertible setups, and what to compare when choosing among available radial tire options.
Tire Size & Fitment
What tire size fits a 2016 Mercedes-Benz E400?
The 2016 Mercedes-Benz E400 uses three primary 18-inch radial sizes: 235/40R18, 255/35R18, and 245/40R18. Sedan and 4Matic sedan models use 245/40R18, while coupe, convertible, and 4Matic coupe versions use a staggered setup with 235/40R18 in front and 255/35R18 in the rear.
The practical question is which body style and wheel position your car actually has. A sedan owner can focus on one square size, but coupe and convertible owners need to match front and rear positions correctly. It is also smart to confirm the wheel package on the car if it has been changed from stock-style sizing.
What size rim does a 2016 Mercedes-Benz E400 use?
The tire sizes associated with the 2016 Mercedes-Benz E400 in this fitment group all use an 18-inch rim diameter. That applies whether the car takes 235/40R18, 255/35R18, or 245/40R18, so the common denominator is an 18-inch wheel rather than multiple rim diameters.
That does not mean every 18-inch wheel is suitable for every E400 tire size. Width still matters, especially on staggered front-and-rear applications where the rear tire is wider. Before replacing tires, verify the actual wheel diameter and width on the car so the chosen tire matches the wheel and the vehicle’s intended setup.
Why does the 2016 Mercedes-Benz E400 have more than one tire size?
More than one tire size appears on the 2016 Mercedes-Benz E400 because the model line includes both sedan fitment and staggered coupe or convertible fitment. The sedan uses 245/40R18 at all four corners, while coupe and convertible versions split tire sizing between the front and rear axles.
That difference changes how replacement should be approached. Sedan owners can usually shop one size for a full set, but staggered cars need the front and rear positions handled separately. Looking only at the model name is not enough, so confirm body style and tire position before choosing a product or comparing specifications.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 tire for a 2016 Mercedes-Benz E400?
Start with the role that 245/40R18 plays on the 2016 Mercedes-Benz E400, since it is the sedan size rather than the staggered coupe or convertible fitment. Then compare radial tire series, brand, sidewall style, rim-width suitability, and any load figures shown for the specific tire you are considering.
The available range in this size is broad enough that appearance and intended use can shape the decision. Blackwall choices give a more understated modern look, while redline and raised white letter options change the car’s visual character. It also helps to confirm that all four wheels on the sedan share the expected width before selecting a set.
What sidewall styles are available for 2016 Mercedes-Benz E400 tires?
Blackwall is the predominant sidewall style across the 2016 Mercedes-Benz E400 tire sizes, especially in 235/40R18 and 255/35R18. In 245/40R18, the selection also includes redline and RWL, which means raised white letter, through Pro-Trac Street Pro III offerings.
Sidewall style mainly affects appearance, so the right choice depends on whether the goal is a subtle modern presentation or a more assertive custom look. It is still important to start with the correct tire size for the car’s body style and wheel position, since sidewall preference comes after fitment is settled.
What brands offer tires for the 2016 Mercedes-Benz E400?
Available tires for the 2016 Mercedes-Benz E400 come from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. BFGoodrich and Nitto appear across the main metric radial sizes, while M&H Racemaster and Pro-Trac are part of the 245/40R18 selection for sedan applications.
Brand alone should not drive the decision. It makes more sense to narrow the choice by the exact size your E400 uses, then compare the tire series within that size and the type of look or use you want. That approach keeps the focus on correct fitment first and product character second.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Mercedes-Benz E400?
A period-style approach for a 2016 Mercedes-Benz E400 usually starts with keeping the correct original-format metric radial size for the specific body style and wheel position. For a sedan, that means 245/40R18 all around, while coupe and convertible models need the proper staggered front and rear sizes preserved.
Appearance can then guide the final choice. Blackwall tires keep the most understated, contemporary presentation for this era of E-Class, while 245/40R18 sedan fitment also opens the door to more expressive redline or raised white letter styling. Buyers chasing exact showroom-era details should compare against model-specific historical references before making a visual statement.
How does tire construction affect the appearance of a restored 2016 Mercedes-Benz E400?
Construction is straightforward on the 2016 Mercedes-Benz E400 because the applicable primary sizes are all radial. That means the appearance difference is less about choosing between bias-ply and radial, and more about how the tire’s tread style, sidewall treatment, and overall visual presence suit the car’s sedan, coupe, or convertible profile.
On this generation of Mercedes-Benz, blackwall radials usually maintain the cleanest era-appropriate look. A sedan fitted with 245/40R18 also has redline and raised white letter options that shift the visual tone away from a stock-style presentation. Matching the tire’s look to the car’s intended finish is just as important as preserving the correct size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mercedes-Benz E400?
Modifications can absolutely affect tire fitment on a 2016 Mercedes-Benz E400, even when the tire size itself is one of the correct primary sizes. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all change clearance at the fender, inner wheelhouse, or steering components.
That matters most on coupe and convertible models with staggered sizing, because front and rear positions already differ. Any E400 with non-original wheels should have both wheel dimensions and available clearance checked before new tires are chosen. A size that suits one setup may need closer review on another car with a different wheel or ride height.
What should I inspect before driving a 2016 Mercedes-Benz E400 on new tires?
Before driving a 2016 Mercedes-Benz E400 on new tires, inspect the wheels for damage, confirm the tire size matches the vehicle’s actual setup, and make sure inflation is set correctly for the installed tires. It is also wise to look over suspension and steering components so the new tires are not being asked to compensate for worn hardware.
A short road test should include listening for rubbing and checking that the car tracks cleanly without vibration. On staggered models, verify that the front and rear tires were mounted in the correct positions. After the first few drives, recheck pressure and take another look at clearances if the car has aftermarket wheels or altered suspension.
How often should tires on a 2016 Mercedes-Benz E400 be inspected?
Tires on a 2016 Mercedes-Benz E400 should be inspected regularly, not just when tread looks low. A quick visual check before routine driving and a closer inspection at service intervals helps catch uneven wear, sidewall damage, punctures, or slow air loss before those issues become more serious.
Cars that sit for longer periods deserve extra attention because age, storage conditions, and underinflation can affect the tires even when mileage stays low. Looking over tread condition, sidewalls, and pressure is especially important on staggered E400 setups, since front and rear tires wear differently and cannot simply be treated as identical all-around fitments.
