Mercedes-Benz E400 Tires

Mercedes-Benz E400 fitment spans eight sizes across the 2013-2018 production run. The sizes are 245/45R17 for 2013-2015, 235/40R18 for 2015-2017, 255/35R18 for 2015-2017, 245/40R18 for 2015-2016, and for 2018 the listings expand to 245/40R19, 245/45R18, 275/35R19, and 275/40R18. The rim diameters tied to those sizes are 17, 18, and 19 inches, depending on year and configuration.

That means the model name alone is not enough to choose correctly. Check the year, verify whether the car uses a square or staggered setup, and physically confirm the wheel diameter before selecting a tire. On 2015 and 2018 cars especially, the correct answer depends on the exact wheel package fitted to the car rather than the year by itself.

The 2015 Mercedes-Benz E400 has four listed sizes because that year bridges more than one wheel package. It includes the earlier 245/45R17 fitment and also several 18-inch sizes: 235/40R18, 255/35R18, and 245/40R18. That kind of split usually reflects different factory wheel combinations rather than one car using all four sizes at the same time.

The practical step is to inspect the actual car instead of relying only on the model year. Read the tire sidewall currently on the car, measure or confirm the wheel diameter, and note whether the front and rear sizes match. Once those details are clear, the 2015 Mercedes-Benz E400 size list becomes much easier to narrow to the correct fitment.

Mercedes-Benz E400 rim diameters vary by year and configuration. Early cars use a 17-inch fitment, 2015 introduces 18-inch sizes, 2016 and 2017 stay within the 18-inch range, and 2018 includes both 18-inch and 19-inch combinations. The tire size itself tells you the wheel diameter in these metric radial sizes, with the final number showing 17, 18, or 19 inches.

That year-to-year change is one of the most important fitment details on this page. If the car has changed hands or wears non-original wheels, verify the actual wheel diameter on the vehicle before selecting tires. A 2018 Mercedes-Benz E400 is the most obvious example, because it can carry either an 18-inch or a 19-inch setup depending on configuration.

On a Mercedes-Benz E400, 245/45R17 is a modern metric radial size. The 245 is the nominal section width in millimeters, 45 is the aspect ratio, meaning the sidewall height is 45 percent of the section width, R identifies radial construction, and 17 is the wheel diameter in inches. That size appears on 2013, 2014, and some 2015 Mercedes-Benz E400 applications.

Understanding the code helps prevent an easy but costly mistake: choosing a size with the right width but the wrong wheel diameter or sidewall profile. If your Mercedes-Benz E400 currently wears 245/45R17, compare that to the wheel on the car and the other tire position before replacing anything, especially on crossover years where 18-inch alternatives were also used.

A 2018 Mercedes-Benz E400 can use either an 18-inch or 19-inch combination, and the listed sizes suggest staggered pairings rather than one universal setup. The 18-inch sizes are 245/45R18 and 275/40R18, while the 19-inch sizes are 245/40R19 and 275/35R19. That means front and rear tire sizes may differ, and the wheel diameter must match exactly.

Start by reading the tire sidewalls currently fitted to the car and confirming the wheel diameter on both axles. Then check whether the front and rear sizes are the same or staggered. On a Mercedes-Benz E400, replacing one axle without confirming the companion size can create a mismatch, so verify the full set before choosing replacements.

Mercedes-Benz E400 tire listings include blackwall, redline, and RWL sidewall styles. Blackwall is available across the full range and is the most common presentation in these sizes. Redline and raised white letter options appear in selected 17-inch and 18-inch sizes through the Pro-Trac Street Pro III line, including 245/45R17, 245/40R18, and 275/40R18.

Sidewall choice is partly visual and partly historical in feel, even on a modern performance sedan. Buyers aiming for a clean factory-style look will usually gravitate toward blackwalls, while redline or RWL options create a more custom or period-performance appearance. The key is to match the sidewall style to the overall look of your Mercedes-Benz E400 rather than choosing by size alone.

Mercedes-Benz E400 tire options here come from M&H Racemaster, BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across the broadest spread of sizes, while Nitto also covers many of the 17-inch, 18-inch, and 19-inch fitments. M&H Racemaster is present in selected sizes with drag-oriented radial offerings, and Pro-Trac adds style-focused radial options in certain applications.

Brand choice should follow how the Mercedes-Benz E400 is actually used. A touring-oriented street car, a weekend performance car, and a custom-built car may all point a buyer toward different tread families or sidewall styles. Once the exact size is confirmed, compare the available brands within that size rather than assuming every brand is offered across the entire model range.

Mercedes-Benz E400 tires are offered in several series, including Drag Radial, g-Force Sport Comp 2, g-Force Comp 2 AS, Nitto NT555 G2, g-Force Phenom T/A, and Street Pro III. All are radial constructions, but they differ in purpose and character: some emphasize street performance, some all-season usability, some drag-race application, and some add distinctive sidewall styling. The available series vary by size, so the choices change across the E400 year range.

That makes the buying process a two-step decision. First confirm the correct size and wheel diameter for your Mercedes-Benz E400, then compare the series available in that size based on how the car is driven and how you want it to look. A car used for normal road driving will be evaluated differently from one built around straight-line performance or custom presentation.

A Mercedes-Benz E400 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and major temperature swings. Keep the tires properly inflated and avoid long periods with one tire carrying a concentrated load in the same contact patch. If the car sits for extended intervals, moving it slightly from time to time can help reduce flat-spotting on low-profile radial tires.

Storage habits matter because the E400 uses performance-oriented sizes with relatively short sidewalls, and those tires can show age or deformation more quickly when neglected. Good storage is not just cosmetic preservation; it directly affects ride quality and road behavior when the car returns to use. A covered, climate-stable garage is far better than a damp or sun-exposed space.

Tires on a Mercedes-Benz E400 should be inspected regularly even if the car is driven only occasionally. Check inflation, sidewall condition, tread wear pattern, and any signs of impact damage or aging before routine use, and inspect again after long storage periods. On staggered or performance wheel packages, uneven wear can develop quickly if alignment or pressure is off.

A practical routine is to look the tires over before every outing and give them a more thorough inspection at least seasonally. Pay close attention to the inner shoulder areas that can be harder to see on wide, low-profile fitments. Catching a pressure loss, sidewall bruise, or abnormal wear early is far easier than discovering it after the Mercedes-Benz E400 is already on the road.

A Mercedes-Benz E400 tire should be replaced when it shows age cracking, sidewall damage, impact injury, persistent vibration, irregular wear, or any loss of structural confidence, even if the tread still looks usable. Collector and weekend-driven cars often age their tires out before they wear them out. Low mileage is not a reliable sign that an older tire remains suitable for road use.

The best approach is to evaluate both age and condition together, especially on a performance sedan that can place real load on its tires. If a Mercedes-Benz E400 has sat for long periods or has unknown tire history, treat visual condition as only part of the picture. A careful inspection by a knowledgeable tire professional is the right next step when any age-related concern appears.

Mercedes-Benz E400 fitment across 2013-2018 includes 245/45R17, several 18-inch sizes, and in 2018 both 18-inch and 19-inch combinations. The available replacement products here are all radial tires, but the exact original tire brand or series for an individual car is not established by the size listings alone. What can be confirmed with confidence is the applicable size range by year and wheel configuration.

For an originality-minded owner, the best path is to verify the factory wheel package and then choose a tire that matches the correct size and visual character for the car. Sidewall appearance can matter nearly as much as size on a preservation-minded modern classic. If your Mercedes-Benz E400 is being kept close to factory presentation, begin with the proper wheel diameter and staggered or square arrangement.

Correct tire fitment can affect both presentation and perceived correctness on a Mercedes-Benz E400, especially as these cars move further into collector territory. The right size, proper front-to-rear relationship, and an appropriate sidewall style all contribute to whether the car looks coherent and properly set up. An obviously incorrect wheel diameter or mismatched staggered pairing can stand out immediately.

For owners concerned with value, the safest course is to keep the tire size aligned with the specific year and wheel package fitted to the car. Judges, marque enthusiasts, and informed buyers tend to notice details such as stance, sidewall profile, and whether the tire package suits the chassis. A Mercedes-Benz E400 presented with correct proportions generally reads as better cared for and more authentic.

Mercedes-Benz E400 tire choices here include blackwall, redline, and RWL sidewall styles, but blackwall is the most broadly available and the most natural fit for a factory-style presentation. Redline and raised white letter versions appear in select sizes and give the car a more customized or retro-performance look. The correct choice depends on whether the goal is restoration-minded restraint or a deliberate visual statement.

If your Mercedes-Benz E400 is being returned to a near-original appearance, blackwall is usually the most conservative and convincing direction. If the car has been modified with custom wheels, suspension, or a more aggressive theme, redline or RWL can be part of that personality. Sidewall style does not change the need to match the exact size and wheel diameter first.

The listed Mercedes-Benz E400 tires are modern radial designs, and many are clearly intended for street use in the appropriate size and wheel diameter. Safety on public roads depends on choosing the exact fitment the car requires and making sure the tires are in sound condition, correctly inflated, and matched properly across the axle or staggered setup. A correct tire in the wrong size is not a safe substitute.

Before regular road use, confirm that the Mercedes-Benz E400 does not have mixed wheel diameters, mismatched tire heights, or uneven wear from an earlier setup. Performance sedans respond noticeably to tire differences, so consistency matters. The right road-use decision starts with exact fitment, then moves to condition, age, inflation, and alignment.

Before driving a Mercedes-Benz E400, check cold tire pressures, inspect the sidewalls and tread for damage, and confirm that the front and rear sizes match the car's intended setup. On years with staggered applications, verify that the companion sizes are paired correctly. Also look for uneven wear, which can point to alignment or suspension issues that affect both handling and tire life.

That quick inspection matters because the E400 uses low-profile performance sizes that can be sensitive to pothole damage, underinflation, and storage-related flat spotting. A minute or two in the garage can reveal issues that are easy to miss once the car is moving. If anything looks questionable, resolve it before taking the Mercedes-Benz E400 out on the road.

Appropriate speed for a Mercedes-Benz E400 always depends on the exact tire fitted, its condition, inflation, and whether the setup is correct for the car. Many of the listed products carry modern performance sizing and are intended for contemporary road use, but age, storage history, and condition still matter more than appearance alone. A tired or damaged performance tire should never be trusted simply because the tread remains deep.

The practical rule is to drive within the limits of the tire's condition and the car's actual setup, not the theoretical capability of the chassis. If the Mercedes-Benz E400 has recently been returned to service or wears older tires of uncertain history, begin cautiously and reassess after inspection. Stable pressures, proper matching, and sound condition come before any high-speed use.
