The 2014 Mercedes-Benz E400 sits in the modern luxury-sport portion of the E-Class lineup, blending everyday comfort with the composed road manners buyers expect from a Mercedes sedan. At this level, tire choice matters as much for ride character and steering response as it does for appearance. The 2014 Mercedes-Benz E400 uses a 245/45R17 radial tire on a 17-inch rim, giving this page a very focused fitment story. Within that size, choices range from performance-oriented blackwall radials to specialty styles such as raised white letter and redline. The real decision is matching the tire to the car's intended use, wheel setup, and visual direction.
Which Tire Size Is Right for The 2014 Mercedes-Benz E400
The 2014 Mercedes-Benz E400 uses one primary tire size: 245/45R17. It is a radial fitment on a 17-inch rim, and the covered E400 Hybrid sub-model uses the same size. That means the main decision is not which primary size fits, but which 245/45R17 tire best suits the car's road use, performance expectations, and preferred sidewall appearance.
A 245/45R17 tire uses a 245-millimeter section width, a 45-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2014 Mercedes-Benz E400, this is the core fitment and it reflects a modern performance-oriented sizing format rather than a vintage bias-ply system. Available choices in this size include blackwall options from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, along with RWL and redline variations in the Pro-Trac Street Pro III series. Choosing among them comes down to intended use, wheel-width compatibility, and whether the car is being kept visually understated or given a more distinctive look.
Sub-model fitment is straightforward here because the covered E400 Hybrid uses the same primary tire size as the 2014 Mercedes-Benz E400. Checking the exact sub-model still matters before purchase, especially if the car has had wheel, suspension, or appearance changes over time.

Tire Size & Fitment
What tire size fits a 2014 Mercedes-Benz E400?
The 2014 Mercedes-Benz E400 uses a 245/45R17 radial tire. That size combines a 245-millimeter section width, a 45-series profile, and a 17-inch rim diameter, making it a modern metric performance fitment rather than a vintage sizing format.
Using the correct size is the starting point, but it is not the only fitment check that matters. The wheel on the car should still be confirmed as a 17-inch setup, and any aftermarket wheel or suspension change should be reviewed before choosing among available 245/45R17 tires.
What size rim does a 2014 Mercedes-Benz E400 use?
The primary tire fitment for the 2014 Mercedes-Benz E400 is built around a 17-inch rim. That rim diameter matches the 245/45R17 tire size, where the final number in the size code identifies the wheel diameter the tire is intended to mount on.
Rim diameter should be confirmed before anything else, especially on a car that may have been changed from its original wheel package. Some 245/45R17 products also call for specific rim-width ranges, so wheel width matters too when comparing one tire option against another.
Does the 2014 Mercedes-Benz E400 Hybrid use the same tire size?
Yes. The covered 2014 Mercedes-Benz E400 Hybrid uses the same 245/45R17 radial tire size as the 2014 Mercedes-Benz E400. That keeps sub-model fitment simple and lets the buying decision focus more on tire type, sidewall style, and intended driving use.
Shared size does not automatically mean every car is wearing the same wheels today. A used or modified E400 Hybrid should still be checked for wheel changes, stance changes, or clearance issues before selecting a replacement tire from the available 245/45R17 options.
Choosing the Right Tire
What should I consider when choosing a 245/45R17 tire for a 2014 Mercedes-Benz E400?
Start with the required 245/45R17 size and radial construction, then compare the tire's intended role. The available choices include street-performance radials, an all-season radial, and a drag-race-oriented radial, so the right pick depends on whether the car is driven mainly on the street or used in a more specialized way.
Appearance can matter just as much as category on a car like the E400. Some options stay understated with a blackwall sidewall, while others add a raised white letter or redline presentation, and wheel-width compatibility should be checked before narrowing the field.
What sidewall styles are available for 2014 Mercedes-Benz E400 tires?
The available 245/45R17 tires for the 2014 Mercedes-Benz E400 include blackwall, RWL, and redline sidewall styles. Blackwall keeps the look subtle and modern, while RWL gives the tire a raised white letter appearance and redline adds a more distinctive visual accent.
Sidewall choice does not change the vehicle's required tire size, but it can change the overall presentation of the car quite a bit. Choosing among those styles usually comes down to whether the E400 is being kept close to a restrained luxury look or given a more personalized appearance.
What brands offer tires for the 2014 Mercedes-Benz E400?
Available 245/45R17 tires for the 2014 Mercedes-Benz E400 include options from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Those brands cover several product types, from performance street radials and all-season designs to drag-race and style-focused choices.
Brand alone should not be the only filter. It helps to compare the tire series, sidewall treatment, intended use, and wheel-width specification so the tire suits both the way the car is driven and the appearance the owner wants from the finished setup.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Mercedes-Benz E400?
A period-style approach on a 2014 Mercedes-Benz E400 usually starts with staying in the correct 245/45R17 size and choosing a radial that matches the car's intended visual direction. Blackwall tires preserve the most restrained late-model luxury look, while RWL or redline options create a more customized presentation.
Because this is a modern E-Class rather than a vintage bias-ply application, appearance choices are more about taste than historical restoration rules. Matching the tire to the wheel design, ride height, and overall look of the car will usually matter more than chasing a single style formula.
How does tire construction affect the appearance of a restored 2014 Mercedes-Benz E400?
On the 2014 Mercedes-Benz E400, tire construction is straightforward because the primary fitment is radial. That means appearance differences come less from bias-ply versus radial shape and more from sidewall treatment, tread category, and the overall stance created by the wheel-and-tire package.
A clean blackwall usually gives the car a contemporary factory-inspired look, while RWL or redline sidewalls shift it toward a more individualized style. Keeping the correct 245/45R17 size helps preserve proportion, especially if the goal is a balanced, well-finished restoration or presentation car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Mercedes-Benz E400?
Yes. Even though the primary size is 245/45R17, modifications can change whether a given tire works comfortably on the car. Aftermarket wheels may alter width or offset, and suspension changes can affect fender, inner-wheelhouse, or steering clearance in ways the original setup did not.
That is why the car's actual wheel-and-tire package should be checked before replacing tires. Measuring the installed wheel, confirming the 17-inch diameter, and looking for any signs of rubbing during full steering lock or suspension movement can prevent an expensive mismatch.
What should I inspect before driving a 2014 Mercedes-Benz E400 on new tires?
Before putting a 2014 Mercedes-Benz E400 back into regular use on new tires, inspect the wheels for damage, confirm proper inflation, and make sure the tires are seated correctly on the rims. A quick visual check for sidewall damage, unusual tread wear, and valve-stem condition is also worthwhile.
The rest of the chassis deserves attention too. Alignment condition, suspension wear, and brake issues can affect how a new set of 245/45R17 tires behaves, and a short test drive should be used to confirm smooth tracking, no vibration, and no interference at turning or compression points.
How often should tires on a 2014 Mercedes-Benz E400 be inspected?
Tires on a 2014 Mercedes-Benz E400 should be inspected regularly rather than only when tread looks low. Pressure loss, shoulder wear, sidewall cuts, and impact damage can develop well before a tire appears worn out, especially on a performance-oriented 45-series radial.
A practical routine is to look them over before longer drives and to check pressure on a consistent schedule. Cars that sit for extended periods still need attention, since age, storage conditions, and long static loads can affect tire condition even when mileage stays relatively low.
