2020 Mercedes-Benz E450 Tires

The 2020 Mercedes-Benz E450 uses four tire sizes: 245/45R18, 245/40R19, 275/40R18, and 275/35R19. The 245-width sizes are used on 18-inch and 19-inch applications across several E450 sub-models, while the wider 275-width sizes appear on rear staggered coupe and cabriolet setups.

The right choice depends on more than the model name alone. Check whether the car has 18-inch or 19-inch wheels and whether it uses the same size front and rear or a wider rear tire. Matching the existing wheel diameter and axle position is the first step before comparing brands, tire series, or sidewall presentation.

The 2020 Mercedes-Benz E450 uses either 18-inch or 19-inch rims, depending on the tire size and vehicle configuration. The 245/45R18 and 275/40R18 sizes use 18-inch rims, while 245/40R19 and 275/35R19 use 19-inch rims.

That rim difference matters because the same model can appear with two wheel diameters and, on some coupe and cabriolet applications, different sizes front and rear. Before ordering tires, verify the wheel size stamped on the wheel or confirm the current tire size already installed. A correct diameter match comes before any decision about brand, tread style, or appearance.

No, not every 2020 Mercedes-Benz E450 sub-model uses the same tire size. Sedan, wagon, and several coupe or cabriolet applications share the 245-width sizes on either 18-inch or 19-inch wheels, while coupe and cabriolet rear positions use the wider 275/40R18 or 275/35R19 sizes.

That makes the sub-model and wheel setup important, especially on cars with staggered front-and-rear fitment. A sedan or wagon owner may simply need to confirm wheel diameter, but a coupe or cabriolet owner should check front and rear sizes separately. Using the correct axle-specific size helps preserve the intended stance and avoids mixing front and rear fitments incorrectly.

Start with the exact tire size already used on the car: 245/45R18, 245/40R19, 275/40R18, or 275/35R19. From there, compare construction, rim-width compatibility, load figures where shown, tire weight, and whether the car uses a square setup or a wider rear staggered arrangement.

After size is confirmed, the real choice becomes product character. Some options are all-season oriented, while others sit in more performance-focused series such as g-Force Sport Comp 2, g-Force Phenom T/A, or Nitto NT555 G2. Sidewall appearance can matter too, especially in 275/40R18 where blackwall, redline, and raised white letter options are available.

Tires for the 2020 Mercedes-Benz E450 are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across all four fitment sizes, Nitto is available in several 18-inch and 19-inch applications, and Pro-Trac appears in 275/40R18.

Brand choice should follow fitment, not replace it. Once the correct size is confirmed, compare each brand's available series, sidewall style, and rim-width range for that specific size. That approach is especially useful on staggered coupe and cabriolet setups, where the front and rear tires may not have the same product mix or visual treatment.

Blackwall is the standard sidewall style across most available 2020 Mercedes-Benz E450 tire sizes. In the 275/40R18 rear fitment, sidewall choices expand to include redline and RWL, which is a raised white letter presentation.

That means appearance choices are broader on some 18-inch rear staggered applications than on the front sizes or the 19-inch options. If visual balance matters, confirm the exact rear size before selecting a style. A blackwall keeps a more understated modern look, while redline or raised white letters create a more pronounced custom or enthusiast-oriented presentation.

Tire construction is straightforward on the 2020 Mercedes-Benz E450 because the applicable fitments are radial sizes in modern metric form. That means the visual difference is less about bias-ply versus radial styling and more about profile, wheel diameter, and whether the car uses a square or staggered setup.

Appearance changes most noticeably when moving between 18-inch and 19-inch fitments or selecting different rear sidewall styles in 275/40R18. A lower-profile 19-inch package gives the car a sharper visual stance, while 18-inch fitments read slightly fuller at the sidewall. Matching front and rear sizing correctly is important if the goal is to preserve the intended proportion of the car.

For a 2020 Mercedes-Benz E450, blackwall is the most restrained and contemporary-looking sidewall style among the available fitments. It is offered across the full range of 18-inch and 19-inch sizes, while redline and raised white letter choices appear in 275/40R18 for a more assertive rear presentation.

The right look depends on whether the goal is to keep the car visually close to a modern luxury-touring presentation or to add a more customized accent. On an E450 with 18-inch staggered rear fitment, sidewall styling can have a larger visual effect because the rear tire is already wider. Keeping the front and rear appearance coordinated usually gives the cleaner result.

Yes, modifications can affect tire fitment on a 2020 Mercedes-Benz E450. Aftermarket wheels, changes in wheel width, altered offset, lowering, suspension work, or body modifications can all change how 245-width and 275-width tires sit within the wheelwell and how much steering or fender clearance remains.

That is especially important on staggered coupe and cabriolet setups, where the rear tire is already wider than the front. A size that matches the original fitment on paper still needs to be checked against the actual wheel and suspension setup on the car. Clearance at full steering lock and under compression deserves attention before regular road use.

Before driving a 2020 Mercedes-Benz E450 on new tires, inspect the wheel diameter, confirm the exact size at each axle, and check air pressure once the tires are mounted. It is also smart to look over valve stems, wheel condition, and any signs that the car has been fitted with non-stock wheels or suspension parts.

A short road test should include listening for rubbing and watching for vibration or pull, especially if the car uses staggered front and rear sizes. Recheck inflation after the initial drive and keep an eye on tread wear as the tires begin service. Uneven wear early on can point to alignment or setup issues rather than a problem with the tire itself.

Tires on a 2020 Mercedes-Benz E450 should be inspected regularly for pressure, tread condition, cuts, bulges, and signs of uneven wear. On a vehicle that sees seasonal use or longer periods parked, sidewall condition and gradual air loss deserve extra attention before the next drive.

Inspection matters even more when the car uses wider rear tires, because staggered setups can mask wear differences between axles if they are not checked individually. Looking at front and rear tires separately helps catch alignment, inflation, or clearance concerns earlier. Any vibration, rubbing, or repeated pressure loss is a sign to stop and review the tire and wheel setup closely.
