2014 Mercedes-Benz E350 Tires

The 2014 Mercedes-Benz E350 does not use one universal tire size across every configuration. Applicable sizes are 245/45R17, 245/40R18, 235/40R18, and 255/35R18, all in radial construction. Sedan and wagon applications use either 245/45R17 or 245/40R18 depending on package, while coupe and cabriolet models use 235/40R18 in front and 255/35R18 in the rear.

The first step is identifying the exact sub-model and checking whether the car has 17-inch or 18-inch wheels. Coupe and cabriolet versions also require attention to front-versus-rear sizing, since those cars use a staggered arrangement rather than the same size at all four corners.

A 2014 Mercedes-Benz E350 uses either a 17-inch or 18-inch rim, depending on the specific configuration. The 245/45R17 fitment uses a 17-inch rim, while 245/40R18, 235/40R18, and 255/35R18 all use 18-inch rims. That means wheel diameter is one of the most important things to confirm before selecting replacement tires.

Checking the tire sidewall is often the quickest way to verify wheel diameter on the car today. Sport Package sedans and wagons move to 18-inch fitment, while coupe and cabriolet models use 18-inch staggered sizing, so rim diameter and axle position both matter before ordering or mounting tires.

The 2014 Mercedes-Benz E350 was offered in several body styles and equipment combinations, and those configurations do not all use the same wheel and tire package. Standard sedans and some wagons use 245/45R17, Sport Package sedan and wagon versions use 245/40R18, and coupe and cabriolet models use a staggered 235/40R18 front and 255/35R18 rear setup.

That variation means replacement tires should be chosen by exact configuration, not by model name alone. A quick check of the current wheel diameter and whether the car uses the same size front and rear will usually prevent the most common ordering mistake on this generation of E350.

Start with the correct primary size for the exact 2014 Mercedes-Benz E350 configuration, then confirm wheel diameter and whether the car uses a square or staggered layout. After that, compare radial tire series, sidewall style, and rim-width suitability within the correct size. The E350 lineup uses multiple fitments, so correct selection begins with matching the vehicle's actual wheel and axle setup.

Once size is confirmed, the real choice becomes intended use and presentation. A blackwall performance radial will suit many drivers, while some 17-inch and 18-inch sizes also offer redline or raised white letter styling for a more distinctive look. Rim-width specs and load figures are also worth comparing before final selection.

Blackwall is the most common sidewall style across the available 2014 Mercedes-Benz E350 tire sizes. In 245/45R17 and 245/40R18, there are also Pro-Trac Street Pro III options with raised white letter and redline sidewalls. The 235/40R18 and 255/35R18 choices shown for coupe and cabriolet staggered applications are blackwall only.

That makes sidewall styling part of the decision mainly on the sedan and wagon fitments that use 245-width tires front and rear. Buyers who want a more understated appearance can stay with blackwall, while those looking for a more custom or enthusiast-oriented presentation may want to compare the redline and RWL alternatives carefully.

Tires for the 2014 Mercedes-Benz E350 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on the size. BFGoodrich appears across all four fitments with several g-Force and Phenom series choices, while Nitto also covers all four sizes. M&H Racemaster and Pro-Trac are present in selected 245-width applications.

Brand choice should be treated as part of the overall tire-selection process rather than the only decision. It still helps to compare each brand's available tire series, sidewall treatments, rim-width ranges, and intended use, especially because the E350 lineup includes both standard 17-inch and sport-oriented 18-inch fitments.

The 2014 Mercedes-Benz E350 uses radial tires across all of its primary fitments, so the main appearance differences come less from construction changes and more from tire series and sidewall treatment. Most available options are blackwall, which suits the clean, modern character of the car. In 245/45R17 and 245/40R18, redline and raised white letter choices create a noticeably different visual statement.

Appearance decisions on a newer collector Mercedes often depend on whether the goal is a stock-looking presentation or a more personalized one. Matching the tire to the car's wheel package matters just as much as sidewall style, because an incorrect rim diameter or staggered setup will look wrong before it ever reaches the road.

Correct tire fitment matters on a 2014 Mercedes-Benz E350 restoration because the car's proportions and stance depend heavily on the right size and wheel combination. This model spans 17-inch standard fitments, 18-inch Sport Package applications, and staggered 18-inch coupe and cabriolet setups. Using the wrong tire size can alter the car's appearance even when the tire physically mounts to the wheel.

Restoration-minded buyers should confirm the exact body style, package, and axle layout before choosing a tire. If originality is especially important, compare the current wheel setup to vehicle-specific records or marque references, then choose among the available sidewall and tire-series options with that visual target in mind.

Yes, modifications can affect tire fitment on a 2014 Mercedes-Benz E350 even when the tire size itself looks close to stock. Aftermarket wheels can change width or offset, suspension changes can alter clearance, and body or fender modifications can affect how much room is available during steering and suspension travel. Those factors matter on both 17-inch and 18-inch E350 setups.

That check becomes even more important on coupe and cabriolet models with staggered 18-inch sizing. An E350 that no longer has its original wheel package should be measured carefully before replacement tires are chosen, especially at full steering lock and under compression where rubbing problems are more likely to appear.

Before driving a 2014 Mercedes-Benz E350 on new tires, inspect wheel condition, confirm proper tire pressure, and make sure each tire size is mounted in the correct position. On staggered cars, verify that 235/40R18 tires are in front and 255/35R18 tires are in the rear. It is also wise to look over alignment condition, valve stems, and overall clearance around the suspension and fenders.

A short, careful test drive helps confirm that the car tracks properly and has no rubbing, vibration, or unusual noise. Rechecking pressure after initial use is worthwhile, especially on collector or low-mileage cars that may have sat for long periods before receiving fresh tires.

Tires on a 2014 Mercedes-Benz E350 should be maintained with regular pressure checks, visual inspections, and periodic review of tread condition and wear pattern. Look for cracking, bulges, cuts, uneven wear, or signs of slow air loss. On cars that are driven infrequently, tire age and storage conditions matter just as much as tread depth because time can degrade rubber even with limited mileage.

Keeping the suspension and alignment in good condition helps the tires wear as intended, especially on 18-inch sport and staggered setups. Storage away from prolonged sunlight, excess heat, and ozone sources can also help preserve tires on a collector-kept E350 that spends more time parked than on the road.
