The 2018 Mercedes-Benz E43 AMG blends midsize luxury sedan refinement with AMG-tuned performance and 4Matic traction, making tire fitment an important part of how the car looks and drives. On this model, the key decision is not a vintage bias-ply versus radial question, but confirming whether the car is on the 19-inch or 20-inch wheel setup and matching the front and rear staggered sizes correctly. The front uses either 245/40R19 or 245/35R20, while the rear uses either 275/35R19 or 275/30R20. Available choices center on blackwall radial performance tires from BFGoodrich and Nitto, so wheel size, axle position, and intended road use should guide the selection.
Which Tire Size Is Right for The 2018 Mercedes-Benz E43 AMG
The 2018 Mercedes-Benz E43 AMG uses four primary tire sizes across a staggered front-and-rear setup, and those sizes are split between 19-inch and 20-inch wheel packages. The first step is confirming wheel diameter, then matching the correct front and rear sizes to the car. Once that is settled, the choice becomes selecting the right radial tire by series, brand, and fitment details for the wheel in use.
245/35R20 is a metric radial size in which 245 is the section width in millimeters, 35 is the aspect ratio, and 20 is the wheel diameter in inches. On the 2018 Mercedes-Benz E43 AMG, this is a front tire size used with the 20-inch wheel setup and it keeps the staggered fitment matched to the wider rear tire. Available options include blackwall radial tires from BFGoodrich and Nitto across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size is the right one to evaluate when the car has 20-inch front wheels and performance-oriented tire choice matters.
245/40R19 is a metric radial size that identifies a 245-millimeter section width, a 40-series profile, and a 19-inch rim diameter. On the 2018 Mercedes-Benz E43 AMG, it serves as the front tire size for the 19-inch staggered setup, paired with a wider rear tire size on the same wheel diameter. BFGoodrich offers this size in blackwall form through the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A lines. This size deserves attention when the car is equipped with 19-inch front wheels and the goal is to keep the proper front-to-rear sizing relationship intact.
275/30R20 is a metric radial size with a 275-millimeter section width, a 30-series profile, and a 20-inch wheel diameter. On the 2018 Mercedes-Benz E43 AMG, this is a rear tire size for the 20-inch staggered configuration, giving the car the wider rear footprint that belongs with the matching 20-inch front size. In this fitment, the available product choice is a blackwall Nitto NT555 G2 radial. This size should be evaluated as part of a matched rear fitment whenever the E43 AMG is running the 20-inch wheel package rather than the 19-inch setup.
275/35R19 is a metric radial size where 275 is the nominal section width in millimeters, 35 is the aspect ratio, and 19 is the wheel diameter in inches. For the 2018 Mercedes-Benz E43 AMG, it is the rear tire size used with the 19-inch staggered arrangement, complementing the narrower 245/40R19 front tire. Available blackwall choices come from BFGoodrich and Nitto, with series including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to compare when confirming 19-inch rear fitment and weighing product differences within that wheel package.
Sub-model fitment on the 2018 Mercedes-Benz E43 AMG is straightforward once axle position is identified, because the front and rear use different sizes in a staggered arrangement. Checking whether the tire is for the front or rear, and whether the car has 19-inch or 20-inch wheels, is what matters most here.

Tire Size & Fitment
What tire size fits a 2018 Mercedes-Benz E43 AMG?
The 2018 Mercedes-Benz E43 AMG uses a staggered tire setup, so the front and rear sizes are different. Front fitments are 245/40R19 or 245/35R20, while rear fitments are 275/35R19 or 275/30R20. All of these are radial sizes.
The right choice depends on two things: axle position and wheel diameter. A front tire should not be selected from the rear sizes, and a 19-inch tire should not be mixed onto a 20-inch wheel. Checking the existing wheel and reading the current tire size is the quickest way to confirm which pair belongs on the car.
What size rim does a 2018 Mercedes-Benz E43 AMG use?
The 2018 Mercedes-Benz E43 AMG uses either 19-inch or 20-inch rims, depending on the wheel package on the car. The 245/40R19 and 275/35R19 sizes belong to 19-inch wheels, while the 245/35R20 and 275/30R20 sizes belong to 20-inch wheels.
That rim diameter is the first fitment detail to confirm before comparing tires. Once wheel size is verified, the next step is matching the correct front and rear tire sizes to that diameter. On a car with replacement wheels, the wheel itself should be checked rather than assuming the original setup is still in place.
Why does the 2018 Mercedes-Benz E43 AMG have more than one tire size?
The 2018 Mercedes-Benz E43 AMG has more than one tire size because it uses a staggered layout and was fitted with more than one wheel diameter. The front axle uses narrower 245-width tires, while the rear axle uses wider 275-width tires, with both 19-inch and 20-inch combinations available.
That means tire selection is based on the car’s exact wheel setup, not just the year, make, and model. Owners should confirm whether the car has 19-inch or 20-inch wheels and then keep the front and rear sizes properly paired. Mixing unmatched staggered sizes can complicate handling balance, clearance, and overall fitment.
Choosing the Right Tire
What should I consider when choosing a 2018 Mercedes-Benz E43 AMG tire?
Start with the basics: confirm whether the tire is for the front or rear and verify whether the car is on 19-inch or 20-inch wheels. The 2018 Mercedes-Benz E43 AMG uses a staggered radial setup, so the correct size must match both axle position and rim diameter.
After size is settled, compare the available tire series, brand, rim-width suitability where shown, and any load information that appears with the product. It also helps to think about how the car is used, since some owners want a more performance-focused feel while others may prefer an all-season-oriented option within the proper fitment.
What brands offer tires for the 2018 Mercedes-Benz E43 AMG?
Tires for the 2018 Mercedes-Benz E43 AMG are available from BFGoodrich and Nitto in the sizes covered here. Depending on the exact front or rear fitment, the available choices include several BFGoodrich g-Force series options and Nitto NT555 G2 fitments.
Brand choice should still come after size confirmation, because the available assortment differs by wheel diameter and axle position. A 20-inch rear fitment has fewer choices than some of the other sizes, while the 19-inch front and rear sizes offer a broader comparison. That makes the exact tire size just as important as the brand name.
What tire series are available for the 2018 Mercedes-Benz E43 AMG?
The tire series available for the 2018 Mercedes-Benz E43 AMG include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Availability varies by the specific front or rear size and by whether the car uses 19-inch or 20-inch wheels.
Comparing tire series is useful once the fitment is narrowed to the correct size. Some sizes offer several series choices, while others are much more limited. Looking at the series alongside wheel compatibility, load figures where listed, and the intended use of the car gives a more practical basis for selection than choosing by series name alone.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Mercedes-Benz E43 AMG restoration?
Yes, correct tire fitment still matters on a 2018 Mercedes-Benz E43 AMG restoration, even though this is a modern AMG sedan rather than an older collector car with bias-ply concerns. The car’s staggered radial setup and its 19-inch or 20-inch wheel package are part of its proper visual stance and mechanical fitment.
A restoration-minded owner should first confirm which wheel package belongs on the car and then keep the front and rear sizing relationship correct. Since the available tires here are blackwall radials, the appearance decision is more about maintaining the intended modern performance look than choosing among vintage sidewall treatments or period-style construction changes.
How does tire construction affect the appearance of a restored 2018 Mercedes-Benz E43 AMG?
On the 2018 Mercedes-Benz E43 AMG, tire construction is straightforward because the primary fitments are radial. That means the appearance difference is not a bias-ply-versus-radial issue, but rather how the correct radial size, profile, and staggered front-to-rear proportions preserve the car’s intended visual balance.
Using the wrong profile or mixing 19-inch and 20-inch fitments can change the way the car sits and how the wheel openings appear filled. For a restoration-oriented result, focus on keeping the correct front and rear size pairing, matching the proper wheel diameter, and selecting a blackwall tire that suits the car’s original modern AMG presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Mercedes-Benz E43 AMG?
Yes, modifications can affect tire fitment on a 2018 Mercedes-Benz E43 AMG. Aftermarket wheels, suspension changes, altered ride height, spacers, or brake upgrades can all change the clearance relationship around a staggered setup, even when the tire size itself looks close to the original fitment.
A modified car should be checked at full steering lock and through normal suspension movement before new tires are chosen. Wheel diameter is only part of the picture; wheel width and placement matter too. On an AMG sedan with wide rear tires, even small setup changes can alter fender, liner, or suspension clearance enough to matter.
What should I inspect before driving a 2018 Mercedes-Benz E43 AMG on new tires?
Before driving a 2018 Mercedes-Benz E43 AMG on new tires, inspect the wheels for damage, confirm the correct front and rear sizes were installed, and make sure inflation is set appropriately for the tire and vehicle application. It also helps to check valve stems, balance, and general condition around the mounting surfaces.
A quick walk-around after installation is worthwhile, especially on a staggered car with low-profile tires. Look for any sign of rubbing, uneven seating, or contact near the fender liners. After the first drives, recheck pressure and pay attention to vibration or pull, since those symptoms can point to balance, alignment, or clearance issues.
How should tires on a 2018 Mercedes-Benz E43 AMG be maintained?
Tires on a 2018 Mercedes-Benz E43 AMG should be maintained with regular pressure checks, routine visual inspections, and prompt attention to uneven wear. Because this car uses low-profile staggered radial tires, keeping the correct size on each axle and watching for cuts, bulges, punctures, or sidewall damage is especially important.
Owners should also inspect tread wear patterns over time, since they can reveal alignment or suspension issues before they become more serious. A car that sits for long periods still deserves periodic tire inspection for aging and air loss. Keeping the wheels clean and the tires properly inflated helps preserve both road manners and overall fitment integrity.
