2015 Mercedes-Benz E400 Tires

The 2015 Mercedes-Benz E400 uses four primary tire sizes: 235/40R18, 255/35R18, 245/40R18, and 245/45R17. The coupe and convertible use a staggered 18-inch setup with 235/40R18 in front and 255/35R18 in the rear, the sedan uses 245/40R18, and the hybrid uses 245/45R17.

Choosing the right one starts with identifying the exact sub-model and whether the car uses a square or staggered arrangement. Wheel diameter matters just as much, since some E400 versions use 18-inch wheels while the hybrid uses a 17-inch fitment.

A 2015 Mercedes-Benz E400 uses either 18-inch or 17-inch rims, depending on the configuration. The coupe, convertible, and sedan fitments covered here use 18-inch wheels, while the E400 Hybrid uses a 17-inch wheel with its 245/45R17 tire size.

That distinction matters before comparing any tire options, because a 17-inch tire cannot be mounted on an 18-inch rim and vice versa. Checking the wheel itself is especially important if the car has been changed from its original wheel setup or fitted with aftermarket wheels.

The 2015 Mercedes-Benz E400 has more than one tire size because the lineup includes different body styles and wheel configurations. Coupe and convertible models use staggered front and rear 18-inch sizes, the sedan uses a single 18-inch size, and the hybrid uses a separate 17-inch fitment.

That means tire selection is tied to the exact version of the car, not just the model name. Buyers should confirm body style, axle position where applicable, and wheel diameter before replacing a single tire or ordering a full set.

Start with the correct size for the exact E400 configuration, since this model uses different fitments across sedan, hybrid, coupe, and convertible versions. After size, compare radial construction details such as tire series, sidewall style, and rim-width range where that specification is given.

The intended use of the car should guide the final choice. A buyer may prefer a straightforward blackwall performance radial, while another may want a redline or raised white letter presentation on sedan or hybrid applications where those styles are available.

Sidewall style depends on the exact tire size. Blackwall choices are available across all of the E400 fitments here, while redline and RWL options appear in 245/40R18 and 245/45R17 through Pro-Trac Street Pro III products.

That makes sidewall appearance more of a factor on the sedan and hybrid sizes than on the staggered coupe and convertible setup shown here. Matching the sidewall style to the overall look of the car can be worthwhile, but size, wheel diameter, and application still come first.

Tires for the 2015 Mercedes-Benz E400 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on the size. The selection includes g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, NT555 G2, Drag Radial, and Street Pro III series.

The most useful way to compare those choices is by the exact fitment you need and the style of tire you want on the car. Some sizes lean toward blackwall performance radials, while others also open the door to redline or raised white letter appearance options.

A period-style approach for a 2015 Mercedes-Benz E400 usually begins with keeping the correct original fitment pattern for the exact version of the car, especially the staggered 18-inch coupe and convertible setup versus the square sedan or 17-inch hybrid fitment. After that, the visible character of the tire becomes the next decision.

Blackwall radials maintain the most understated modern luxury presentation, while certain 245/40R18 and 245/45R17 options add redline or RWL styling. Appearance preferences should be balanced against the correct size, the actual wheel on the car, and the way the vehicle will be driven.

On the 2015 Mercedes-Benz E400, tire construction does not create a bias-ply-versus-radial appearance decision because the primary fitments here are radial. The visible differences come more from tire series, sidewall treatment, and whether the car carries a plain blackwall look or a more assertive redline or RWL presentation.

That means appearance planning should focus on the exact size and how the tire complements the body style and wheel choice. On a modern collector-era Mercedes-Benz, keeping the proper staggered or square setup often matters more visually than chasing a dramatic sidewall treatment.

Yes, modifications can affect tire fitment on a 2015 Mercedes-Benz E400 even when the tire size looks close on paper. Wheel changes, altered offsets, suspension lowering, or body modifications can all change the space available around the tire and the way the car handles a staggered or square setup.

Any modified E400 should have its actual wheel diameter and width checked before replacement tires are chosen. Front and rear positions matter on coupe and convertible models, and even the sedan or hybrid should be inspected for clearance at full steering lock and full suspension movement.

Before driving a 2015 Mercedes-Benz E400 on new tires, inspect the wheel for the correct diameter and any damage, confirm the tires are mounted in the proper positions, and check air pressure carefully. It is also smart to verify that no rubbing occurs at steering lock or under normal suspension movement.

A quick follow-up inspection after the first miles can catch issues early. Looking for uneven wear, vibration, air loss, or signs that a front tire and rear tire were mixed on a staggered application helps confirm that the setup is working as intended.

Before a longer drive in a 2015 Mercedes-Benz E400, check tire pressure, tread condition, and the sidewalls for cuts, cracking, bulges, or impact damage. A car with staggered coupe or convertible fitment also deserves a quick review to make sure the front and rear sizes remain correctly matched.

Longer drives put more emphasis on stability and heat management, so even low-mileage tires should be inspected if the car sits often. Any E400 with aftermarket wheels, suspension changes, or a recent tire replacement should have its clearance and wheel compatibility reviewed before heading out.
