The 2019 Mercedes-Benz E300 sits in the modern luxury-sport sedan space, blending the E-Class reputation for refinement with contemporary chassis technology and everyday road manners. Buyers usually approach this car expecting comfort, precise response, and a polished highway feel, which makes correct tire sizing especially important. The 2019 Mercedes-Benz E300 uses radial tire fitments in 225/55R17, 245/45R18, and 245/40R19, all tied to different wheel diameters rather than vintage construction choices. Available tires range from blackwall performance-oriented series to Silvertown Radial options with wide whitewall or redline styling in 17-inch fitment. The key decision is confirming the wheel size already on the car, then matching tire character to road use and appearance goals.
Which Tire Size Is Right for The 2019 Mercedes-Benz E300
Three tire sizes apply to the 2019 Mercedes-Benz E300, and the first step is confirming which wheel diameter is on the car: 17, 18, or 19 inches. Both the E300 Sedan and E300 4Matic Sedan can use these sizes, so the real fitment decision centers on the actual wheel setup, then on the type of radial tire you want within that size.
225/55R17 is a metric radial size that uses a 225 millimeter section width, a 55-series aspect ratio, and a 17-inch rim diameter. On the 2019 Mercedes-Benz E300, this size stays within the modern radial format expected for current road use while also offering the widest appearance variety in the group. Available choices include BFGoodrich performance-oriented g-Force series as well as Silvertown Radial options in blackwall, wide whitewall, and redline form. This size is the one to study closely if the car has 17-inch wheels and appearance matters as much as everyday drivability.
245/40R19 is a metric radial size with a 245 millimeter section width, a 40-series profile, and a 19-inch rim diameter. For the 2019 Mercedes-Benz E300, it represents a lower-profile modern fitment that keeps the vehicle in a contemporary radial tire category rather than any vintage sizing convention. Product choices in this size are centered on BFGoodrich g-Force series tires, all in blackwall form, with distinctions coming from series selection and individual product specifications. This size deserves careful confirmation because the 19-inch rim requirement is specific and cannot be assumed from the other E300 fitments.
245/45R18 is a metric radial size combining a 245 millimeter section width with a 45-series profile on an 18-inch rim. On a 2019 Mercedes-Benz E300, it offers another modern radial fitment choice and sits between the 17-inch and 19-inch options in wheel diameter. Available products include several BFGoodrich g-Force series tires and a Nitto NT555 G2, all in blackwall configuration, so comparison usually comes down to tire series, brand, rim-width compatibility, and other product-level details. This is the size to evaluate when the car is already equipped with 18-inch wheels and you want a straightforward modern performance presentation.
Tire fitment is straightforward across the covered 2019 Mercedes-Benz E300 sub-models because both use the same three radial tire sizes. The important step is not choosing between Sedan and 4Matic Sedan fitment, but confirming whether the car is on 17-inch, 18-inch, or 19-inch wheels.

2019 Mercedes-Benz E300 4Matic Sedan
The 2019 Mercedes-Benz E300 4Matic Sedan uses the same range of radial tire sizes as the other covered E300 configuration, so sub-model naming alone does not narrow the fitment to one size. Tire selection comes down to verifying the wheel diameter on the car and then choosing the right series, sidewall style, and product specifications within that size.
The 2019 Mercedes-Benz E300 Sedan shares the same radial fitment range found across the covered E300 lineup, with 17-inch, 18-inch, and 19-inch wheel-based tire choices. That makes wheel confirmation the key step, followed by deciding whether the goal is a blackwall performance look or a more distinctive 17-inch wide whitewall or redline presentation.
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 E300 Tires for Sale
Available 2019 Mercedes-Benz E300 tires center on 225/55R17, 245/45R18, and 245/40R19 radial fitments from BFGoodrich and Nitto. The main differences in the product grid are tire series, blackwall versus 17-inch wide whitewall or redline styling, and the rim-width ranges tied to each size.
Common questions for the 2019 Mercedes-Benz E300 usually come down to confirming the right wheel-based tire size, understanding the modern metric radial formats, and comparing series, sidewall style, and maintenance considerations before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2019 Mercedes-Benz E300?
The 2019 Mercedes-Benz E300 uses three radial tire sizes: 225/55R17, 245/45R18, and 245/40R19. Both the E300 Sedan and E300 4Matic Sedan can use those sizes, so fitment is tied to the wheel diameter on the car rather than to a unique sub-model-only tire size.
The practical next step is checking the actual wheel setup before choosing a tire. A 17-inch wheel requires 225/55R17, an 18-inch wheel requires 245/45R18, and a 19-inch wheel requires 245/40R19. If the car has been changed from its original wheel package, verify the wheel diameter and width before selecting a replacement tire.
What size rim does a 2019 Mercedes-Benz E300 use?
A 2019 Mercedes-Benz E300 can use 17-inch, 18-inch, or 19-inch rims, depending on which tire size is on the car. The matching tire sizes are 225/55R17 for 17-inch rims, 245/45R18 for 18-inch rims, and 245/40R19 for 19-inch rims.
Rim diameter is the first fitment point to confirm because these tire sizes are not interchangeable across different wheel diameters. After that, compare the tire’s approved rim-width range with the wheel that is actually installed. That matters even when the diameter is correct, especially if the car has aftermarket wheels or a changed wheel-and-tire package.
Do all 2019 Mercedes-Benz E300 sub-models use the same tire size?
The covered 2019 Mercedes-Benz E300 sub-models share the same overall fitment range rather than a single exclusive tire size. Both the E300 Sedan and E300 4Matic Sedan can use 225/55R17, 245/45R18, or 245/40R19, depending on the wheel package installed on the car.
That means the sub-model name alone does not settle the tire purchase. The important check is the wheel diameter currently on the vehicle, because each of the three sizes matches a different rim size. Looking at the sidewall of the existing tire or measuring the wheel is often the quickest way to confirm which fitment applies.
Choosing the Right Tire
What should I consider when choosing a 2019 Mercedes-Benz E300 tire?
Start with the correct size for the wheel already on the car: 225/55R17, 245/45R18, or 245/40R19. From there, compare construction details within the radial category, approved rim-width range, tire series, brand, sidewall style, and any load information that matters to the way the car is used.
A buyer focused on a clean modern look may stay with blackwall performance-oriented options, while someone using 17-inch wheels may also consider wide whitewall or redline styling. It also helps to compare how the car is driven, whether it spends more time cruising or covering daily miles, and whether the wheel setup is still standard.
What sidewall styles are available for 2019 Mercedes-Benz E300 tires?
Sidewall style depends on the size you choose. Blackwall options are available across all three E300 tire sizes, while the 225/55R17 fitment also offers Silvertown Radial choices with a 1.50-inch wide whitewall or a redline sidewall treatment.
That makes the 17-inch fitment the most flexible if appearance is part of the decision. Buyers who want a more traditional or custom-inspired presentation have more room to choose there, while 18-inch and 19-inch choices stay focused on blackwall performance styling. Matching the sidewall treatment to the car’s wheels and overall look usually matters as much as the brand.
What brands offer tires for the 2019 Mercedes-Benz E300?
BFGoodrich appears across all three 2019 Mercedes-Benz E300 sizes, and Nitto is available in 245/45R18. Within BFGoodrich, the available lines include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Silvertown Radial in the 17-inch fitment.
Brand choice is only one part of the comparison. It is just as important to look at which size the tire is offered in, whether the sidewall is blackwall, wide whitewall, or redline, and whether the wheel width on the car matches the tire’s approved range. Those details shape the final choice more than the brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Mercedes-Benz E300?
A period-style approach on a 2019 Mercedes-Benz E300 starts with the wheel diameter already on the car, then moves to sidewall presentation. Among the available choices, 225/55R17 offers the strongest appearance variation because it is available not only in blackwall form but also in Silvertown Radial wide whitewall and redline versions.
That does not make those styles factory-original for every E300, but it does give the car a more distinctive visual direction than the strictly blackwall 18-inch and 19-inch options. Buyers concerned with preserving a specific showroom-era appearance should compare the tire choice against the vehicle’s original wheel and trim presentation before making the change.
Does correct tire fitment matter for a 2019 Mercedes-Benz E300 restoration or preservation project?
Correct tire fitment matters because the E300’s three applicable sizes are tied directly to different wheel diameters. Choosing 225/55R17, 245/45R18, or 245/40R19 is not just a styling decision; it affects whether the tire matches the wheel package that belongs on the car and how the finished vehicle presents itself.
Preservation-minded owners should confirm the actual wheels on the vehicle before selecting tires, especially if the car has changed hands or has seen cosmetic upgrades. Keeping the diameter, profile, and sidewall style aligned with the intended look helps the car feel cohesive, whether the goal is clean modern presentation or a more individualized appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mercedes-Benz E300?
Yes, modifications can affect tire fitment on a 2019 Mercedes-Benz E300 even when the tire size itself looks close to stock. Aftermarket wheels, changes in wheel width, altered offsets, suspension lowering, or body modifications can all change the clearance picture around 225/55R17, 245/45R18, or 245/40R19 tires.
That is why the tire size should be checked against the wheel and the car’s actual stance, not just the model name. Steering clearance, inner-fender space, and suspension travel all deserve attention when a modified car is being re-tired. A careful visual inspection before purchase helps prevent avoidable fitment problems once the tires are mounted.
What should I inspect before driving a 2019 Mercedes-Benz E300 on new tires?
Before road use, inspect the wheel diameter and width, confirm that the new tire size matches the wheel, and look over the car for any signs of rubbing or clearance issues. It also makes sense to check the old tires and wheels for uneven wear patterns, impact damage, or other clues about alignment or suspension condition.
Routine safety checks still matter on a modern E-Class. Set tire pressures correctly, watch for air loss after installation, and inspect the sidewalls and tread area after the first few drives. A short test drive with attention to steering feel, vibration, and noise can reveal whether the tire and wheel package is settled properly.
How often should tires on a 2019 Mercedes-Benz E300 be inspected?
Tires on a 2019 Mercedes-Benz E300 should be inspected regularly, not just when replacement time arrives. A quick visual check every month and a closer inspection before longer drives helps catch uneven wear, cuts, bulges, embedded debris, or pressure loss before those issues become more serious.
Low-mileage cars still need attention because time and storage conditions can age a tire even when tread wear is limited. Looking at sidewall condition, tread depth, and inflation habits is especially useful on a vehicle that may alternate between daily use and long parked periods. Consistent inspection supports ride quality as much as basic tire safety.
