The 2019 Mercedes-Benz E450 sits in the modern E-Class sweet spot, blending luxury-car refinement with the stronger pace and road presence that buyers expect from a contemporary Mercedes grand touring platform. Whether in sedan, wagon, coupe, or cabriolet form, the tire decision centers on radial fitments in 18-inch and 19-inch sizes, with a staggered rear setup appearing on coupe and cabriolet rear positions. Available choices range across BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall treatments depending on size. The right selection comes down to confirming the exact sub-model and wheel diameter, then matching the tire's character to daily use, appearance goals, and the vehicle's current setup.
Which Tire Size Is Right for The 2019 Mercedes-Benz E450
The 2019 Mercedes-Benz E450 uses four primary tire sizes, and the correct one depends on sub-model position and wheel diameter. Both 18-inch and 19-inch fitments are used, so the first step is confirming whether the car is on 18s or 19s and whether you are selecting a front or rear tire on coupe and cabriolet applications. Once that is clear, the real comparison becomes tire series, brand, sidewall style, and the intended balance between appearance and road use.
Fit(s): 4Matic Coupe & Cabriolet, 4Matic Sedan, 4Matic Wagon, Coupe & Cabriolet, and Coupe & Cabriolet Front
Construction: Radial|Rim: 19 in
245/40R19 is a metric radial size: 245 is the section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2019 Mercedes-Benz E450, this size serves as a front-size or all-around fitment depending on the sub-model and wheel package, making wheel confirmation especially important. Available choices are centered on BFGoodrich in g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series, all in blackwall form. This size is the right place to start when your E450 is equipped with 19-inch wheels and you want a modern performance-oriented radial selection.
Fit(s): 4Matic Coupe & Cabriolet, 4Matic Sedan, 4Matic Wagon, Coupe & Cabriolet, and Coupe & Cabriolet Front
Construction: Radial|Rim: 18 in
245/45R18 is a metric radial size with a 245-millimeter section width, a 45-series profile, radial construction, and an 18-inch rim diameter. It is used across several 2019 Mercedes-Benz E450 sub-models as a front-size or square-fitment option, so it is common on cars equipped with 18-inch wheels. Product choices include BFGoodrich and Nitto, with blackwall options across the g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. This size makes sense when the car is on 18-inch wheels and the goal is to compare multiple radial options without changing the original wheel diameter.
275/35R19 is a wider metric radial size: 275 is the section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. On the 2019 Mercedes-Benz E450, this size is used at the rear on coupe and cabriolet applications that carry a staggered 19-inch setup. BFGoodrich and Nitto options are available here, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2, all with blackwall styling. This is the size to evaluate when a rear-position E450 tire needs the correct wider 19-inch fitment rather than a front-size substitute.
275/40R18 is a metric radial size with a 275-millimeter section width, a 40-series profile, radial construction, and an 18-inch rim diameter. It serves as the rear tire size on coupe and cabriolet applications using the staggered 18-inch setup, so it should be matched carefully to the front wheel and tire package already on the car. Available options include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and RWL sidewall treatments depending on the tire series. This size is especially relevant when rear fitment, sidewall appearance, and wheel-width compatibility all matter in the final choice.
Tire fitment on the 2019 Mercedes-Benz E450 varies by sub-model and, in some cases, by axle position. Checking the exact body style and whether the vehicle uses 18-inch or 19-inch wheels is the key step before comparing specific tires.

2019 Mercedes-Benz E450 4Matic Coupe & Cabriolet
This sub-model uses the front-size fitments shared with other E450 configurations, with radial options available in both 18-inch and 19-inch wheel diameters. Tire selection starts with confirming which wheel package is on the car, then comparing the available tire series and overall driving character within the correct size.
The 2019 Mercedes-Benz E450 4Matic Sedan uses the narrower E450 fitments rather than the wider rear staggered sizes used on coupe and cabriolet rear positions. Choosing a tire here is mainly a matter of confirming 18-inch versus 19-inch wheels and selecting among the available radial product lines.
The 4Matic Wagon follows the same primary front-size pattern seen on other non-rear-position E450 applications, with radial fitments available for 18-inch and 19-inch wheels. That makes wheel-diameter confirmation the main fitment step before comparing brand, series, and blackwall tire options.
This sub-model uses the front-size E450 fitments and shares the same radial sizing family found across other front-position applications. The important decision is matching the tire to the actual wheel diameter on the car, especially if the vehicle has been changed from its original wheel package.
Front-position fitment on the coupe and cabriolet uses the narrower E450 tire sizes, with radial options in both 18-inch and 19-inch formats. Tire choice here should stay coordinated with the rear setup so the car keeps the intended staggered relationship and overall fitment balance.
Rear-position fitment on the coupe and cabriolet uses the wider E450 tire sizes, making this the sub-model entry where staggered fitment matters most. Selecting the correct rear tire means confirming 18-inch versus 19-inch wheels first, then comparing the available series and sidewall treatments within that exact rear size.
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.
Best 2019 Mercedes-Benz E450 Tires for Sale
Available 2019 Mercedes-Benz E450 tire choices span BFGoodrich, Nitto, and Pro-Trac depending on size. Buyers can compare blackwall options across several g-Force and NT555 G2 series, while 275/40R18 also adds redline and raised white letter styling for a more distinctive presentation.
Common 2019 Mercedes-Benz E450 tire questions usually come down to identifying the right size for the exact sub-model, confirming 18-inch versus 19-inch wheels, and understanding staggered rear fitment on coupe and cabriolet applications.
Tire Size & Fitment
What tire size fits a 2019 Mercedes-Benz E450?
The 2019 Mercedes-Benz E450 uses four primary tire sizes: 245/45R18, 245/40R19, 275/40R18, and 275/35R19. The narrower 245-section sizes are used on several E450 applications, while the wider 275-section sizes appear at the rear on coupe and cabriolet rear positions with staggered fitment.
The practical step is to confirm the exact sub-model, axle position, and wheel diameter before choosing a tire. A front-position 245 size and a rear-position 275 size are not interchangeable simply because they belong to the same model family, and an 18-inch tire cannot be mounted on a 19-inch wheel.
What size rim does a 2019 Mercedes-Benz E450 use?
A 2019 Mercedes-Benz E450 uses either an 18-inch or 19-inch rim, depending on the tire size and vehicle configuration. The 245/45R18 and 275/40R18 sizes are for 18-inch wheels, while the 245/40R19 and 275/35R19 sizes are for 19-inch wheels.
Wheel diameter is the first fitment detail to verify because it immediately narrows the correct tire choices. After that, check whether the car uses the same size front and rear or a staggered arrangement, especially on coupe and cabriolet applications where the rear tire is wider than the front.
Why does the 2019 Mercedes-Benz E450 have more than one tire size?
The 2019 Mercedes-Benz E450 has more than one tire size because fitment changes with wheel package and, on some versions, by axle position. Some configurations use 18-inch sizes, others use 19-inch sizes, and coupe and cabriolet rear positions use wider 275-section tires than the front.
That means tire selection is not just a year-make-model exercise. Looking at the wheel itself, checking the size already mounted, and confirming whether the car has a staggered setup will keep the replacement process on track and help avoid choosing a tire that matches the model name but not the actual vehicle setup.
Choosing the Right Tire
What should I consider when choosing a 2019 Mercedes-Benz E450 tire?
Start with the exact tire size, wheel diameter, and axle position used on the car. A 2019 Mercedes-Benz E450 may need a 245-section front or square-fitment tire, or a wider 275-section rear tire on coupe and cabriolet applications, and each size has its own range of radial tire choices.
After fitment is confirmed, compare the available tire series, brand options, sidewall style, and wheel-width compatibility for that size. A buyer focused on a clean modern appearance may stay with blackwall options, while someone wanting a more expressive look in 275/40R18 may also consider redline or raised white letter presentations.
What brands offer tires for the 2019 Mercedes-Benz E450?
Tires for the 2019 Mercedes-Benz E450 are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears across all four primary sizes, Nitto is available in several 18-inch and 19-inch applications, and Pro-Trac appears in 275/40R18.
Brand choice should still come after confirming the correct size and wheel diameter. Once the fitment is right, the comparison becomes more useful: some sizes have a broader mix of tire series, while others add appearance choices such as redline or raised white letter sidewalls that may matter as much as the brand name.
What sidewall styles are available for 2019 Mercedes-Benz E450 tires?
Most 2019 Mercedes-Benz E450 tire options are blackwall radials, which is the sidewall style available across the 245/40R19, 245/45R18, and 275/35R19 sizes. The 275/40R18 size expands the appearance choices by adding redline and RWL, or raised white letter, options.
Sidewall treatment will not change the required tire size, but it can strongly affect how the car presents visually. That makes the rear 275/40R18 fitment especially interesting for buyers who want something other than a standard blackwall, provided the tire still matches the car's wheel diameter and rear-position requirements.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Mercedes-Benz E450?
A period-style approach on a 2019 Mercedes-Benz E450 usually means staying with the correct modern radial size for the exact wheel package rather than trying to reinterpret the car with an unrelated fitment. For most applications, that points to blackwall radial tires in the proper 18-inch or 19-inch size.
Appearance still leaves room for choice within the correct fitment. The 275/40R18 rear size offers blackwall, redline, and raised white letter options, but the best visual match depends on whether the goal is a restrained factory-inspired look or a more customized presentation built around the car's current wheels and stance.
Does correct tire fitment matter for a 2019 Mercedes-Benz E450 restoration?
Correct tire fitment matters because the 2019 Mercedes-Benz E450 uses multiple sizes, two rim diameters, and staggered rear applications on certain coupe and cabriolet setups. A tire that is close in appearance but wrong in diameter or position can upset the proportions of the car and complicate proper mounting.
Restoration-minded buyers should verify the actual wheel package on the vehicle before choosing a tire on looks alone. If originality is an important goal, compare the current wheels and tire sizes against vehicle-specific references so the final choice supports both the intended appearance and the car's proper front-to-rear fitment layout.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mercedes-Benz E450?
Yes. A 2019 Mercedes-Benz E450 can be affected by aftermarket wheels, suspension changes, altered ride height, or previous tire substitutions. Those changes matter even more on versions that use wider rear tires, because the front and rear fitments are already different before any modification is introduced.
Checking the actual wheel diameter and width on the car is the best starting point. It also helps to inspect inner clearance, fender clearance, and steering travel before replacing tires, especially if the vehicle no longer sits at stock height or if a previous owner changed the original wheel package.
What should I inspect before driving a 2019 Mercedes-Benz E450 on new tires?
Inspect wheel condition, verify that each tire matches the correct front or rear position, and confirm inflation before road use. It is also wise to look over the suspension and alignment condition, since uneven wear patterns or steering pull can shorten the life of a new tire quickly.
A short initial drive followed by a second inspection is a sensible habit on any E450, especially one with staggered fitment. Recheck pressure, look for any signs of rubbing, and make sure the car tracks cleanly at normal road speeds so the new tires are working with the vehicle setup rather than against it.
How often should tires on a 2019 Mercedes-Benz E450 be inspected?
Tires on a 2019 Mercedes-Benz E450 should be inspected regularly, not just when tread looks low. Routine checks should include air pressure, tread wear across the full width, cuts, bulges, punctures, and any sidewall damage, with extra attention paid to wider rear tires on staggered applications.
A monthly visual inspection is a practical baseline, and any long drive deserves a closer look beforehand. Cars that are driven less often can still develop tire issues from age, storage, or pressure loss, so mileage alone is not enough reason to assume the tires are ready for road use.
