The 2023 Mercedes-Benz Trucks EQB 300 brings modern electric crossover packaging to a nameplate family known for compact luxury and everyday usability. Its quiet driveline, substantial curb presence, and dual-purpose city-and-highway role make tire choice more than a cosmetic decision. For this exact EQB 300 fitment, the key question is not bias-ply versus radial, but whether the vehicle is running 235/55R18 or 235/50R19 radial tires. Both are modern metric radial sizes with very similar overall diameter, but they depend on the wheel package in use. Selecting the right tire starts with confirming the installed rim diameter, then matching the tire's proportions and road-use priorities to the vehicle.
Which Tire Size Is Right for The 2023 Mercedes-Benz Trucks EQB 300
The 2023 Mercedes-Benz Trucks EQB 300 uses two primary tire sizes, and the difference comes down first to wheel diameter. Both sizes are radial metric fitments with closely matched overall height, but one is built for an 18-inch rim and the other for a 19-inch rim. Before choosing a tire, confirm which wheel package is on the vehicle so the size matches the actual rim.
235/50R19 is a modern metric radial size in which 235 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2023 Mercedes-Benz Trucks EQB 300, this size belongs to a 19-inch wheel setup rather than an 18-inch package. Its overall height stays very close to the alternate fitment, so the main distinction is the wheel diameter and sidewall profile. Choose this size only after confirming that the vehicle is equipped with 19-inch rims.
235/55R18 is also a modern metric radial size, with a 235-millimeter nominal section width, a 55-series aspect ratio, radial construction, and an 18-inch rim requirement. For the 2023 Mercedes-Benz Trucks EQB 300, it serves the alternate wheel package and carries nearly the same overall diameter as the 19-inch fitment. That makes it easy to confuse at a glance, even though it is not meant for the same rim. This is the size to evaluate when the vehicle has 18-inch wheels and you want to keep the intended fitment relationship.
Sub-model fitment is straightforward here, but wheel-package confirmation still matters. The EQB 300 4Matic can use either of the two radial sizes, so the real selection step is identifying whether the vehicle is on 18-inch or 19-inch rims.

Frequently Asked Questions
Common questions for the 2023 Mercedes-Benz Trucks EQB 300 usually center on its two tire sizes, 18-inch versus 19-inch wheel fitment, and how to choose the right modern radial setup for the vehicle's actual wheel package and road use.
Tire Size & Fitment
What tire size fits a 2023 Mercedes-Benz Trucks EQB 300?
The 2023 Mercedes-Benz Trucks EQB 300 uses two primary tire sizes: 235/55R18 and 235/50R19. Both are radial metric sizes, and both are associated with the EQB 300 4Matic, so the correct choice depends on the wheel package installed on the vehicle rather than a simple year-make-model lookup alone.
The practical next step is to confirm the actual rim diameter before buying tires. An 18-inch wheel requires 235/55R18, while a 19-inch wheel requires 235/50R19. Even though the two sizes have very similar overall diameter, they are not intended for the same rim, so wheel confirmation comes first.
What size rim does a 2023 Mercedes-Benz Trucks EQB 300 use?
The 2023 Mercedes-Benz Trucks EQB 300 uses either an 18-inch or 19-inch rim, depending on the wheel setup. The 235/55R18 tire belongs to an 18-inch rim, and the 235/50R19 tire belongs to a 19-inch rim.
Checking the wheel itself is important because the two tire sizes are close in overall height and width, which can make them seem interchangeable when they are not. A quick look at the sidewall of the current tire or the wheel specification can prevent ordering the right proportions in the wrong rim diameter.
Why does the 2023 Mercedes-Benz Trucks EQB 300 have more than one tire size?
More than one tire size appears because the 2023 Mercedes-Benz Trucks EQB 300 was fitted with different wheel diameters. The two sizes, 235/55R18 and 235/50R19, keep the vehicle in a similar overall tire-height range while matching different rim packages.
That means the first fitment decision is not choosing between two unrelated sizes, but identifying which wheels are actually on the vehicle now. If the EQB has had wheel changes since new, use the installed rim diameter as the starting point and then verify clearance and load suitability before replacing tires.
Choosing the Right Tire
What should I consider when choosing a tire for a 2023 Mercedes-Benz Trucks EQB 300?
Start with the correct size for the wheel package: 235/55R18 for 18-inch rims or 235/50R19 for 19-inch rims. Both are modern radial metric fitments, so the main concern is matching the tire to the wheel diameter already on the vehicle rather than selecting between different tire constructions.
After size confirmation, compare the tire's intended use with how the EQB 300 is driven. Daily commuting, highway travel, climate, and ride preference all matter, but none of that overrides basic fitment. Proper wheel diameter, compatible proportions, and adequate clearance should be settled before comparing tread design or brand preferences.
How do I choose between the available 235/55R18 and 235/50R19 tires for a 2023 Mercedes-Benz Trucks EQB 300?
The correct choice is determined by the wheel diameter already on the vehicle. A 2023 Mercedes-Benz Trucks EQB 300 with 18-inch wheels uses 235/55R18, while one with 19-inch wheels uses 235/50R19. Both sizes share a similar section width and closely matched overall height, but they are matched to different rims.
Once the wheel diameter is confirmed, compare tires within that exact size instead of cross-shopping the alternate fitment. That keeps the focus on proper wheel compatibility and avoids unnecessary confusion. On a vehicle like the EQB 300, correct sizing is the foundation for ride quality, clearance, and consistent day-to-day road manners.
What rim-fitment details should I compare when choosing 2023 Mercedes-Benz Trucks EQB 300 tires?
Rim diameter is the most important detail to compare on the 2023 Mercedes-Benz Trucks EQB 300 because the vehicle uses both 18-inch and 19-inch tire fitments. The tire size must match the wheel exactly, so 235/55R18 belongs on an 18-inch rim and 235/50R19 belongs on a 19-inch rim.
It also helps to verify that the wheels on the vehicle are the ones actually being used, especially if there has been any change since new. Sidewall markings, wheel stamping, or the current tire size can confirm that. Once rim diameter is settled, then check clearance and overall condition before final tire selection.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Mercedes-Benz Trucks EQB 300 restoration or preservation project?
Correct tire fitment still matters, even on a modern vehicle like the 2023 Mercedes-Benz Trucks EQB 300. The proper starting point is using the size that matches the wheel package on the vehicle, either 235/55R18 or 235/50R19, rather than treating both sizes as universally interchangeable.
For a preservation-minded owner, keeping the intended wheel-and-tire relationship helps maintain the vehicle's original visual balance and avoids avoidable fitment issues. If the goal is to return the EQB 300 to a previous configuration, confirm the installed wheels carefully before replacing tires so the dimensions stay consistent with the setup being preserved.
How does tire size choice affect the appearance of a 2023 Mercedes-Benz Trucks EQB 300?
On the 2023 Mercedes-Benz Trucks EQB 300, appearance changes mainly with the wheel-and-sidewall combination rather than a change in construction type, since both primary fitments are radial. The 235/55R18 size pairs with an 18-inch wheel, while 235/50R19 pairs with a 19-inch wheel and a shorter sidewall profile.
That means the vehicle's stance can look subtly different depending on which factory-style wheel package is in use, even though the two sizes stay close in overall diameter. For a clean, cohesive presentation, match the replacement tire to the actual wheel diameter and avoid mixing size formats that were not intended for that rim.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Mercedes-Benz Trucks EQB 300?
Yes, modifications can affect tire fitment on a 2023 Mercedes-Benz Trucks EQB 300. Changes such as aftermarket wheels, altered offset, suspension adjustments, or body modifications can change the clearance relationship that originally worked with 235/55R18 or 235/50R19.
That is why the current wheel setup should be checked before replacing tires, especially if the vehicle was purchased used or has been personalized. Even when the sidewall size looks familiar, the wrong wheel dimensions can create rubbing, steering-clearance issues, or an unintended stance that complicates an otherwise straightforward tire replacement.
What should I inspect before driving a 2023 Mercedes-Benz Trucks EQB 300 on new tires?
Before road use, inspect the tire installation, confirm that the size matches the wheel diameter, and look over the wheels for damage or irregularities. It also makes sense to check general tire condition, valve stems, inflation pressure, and whether the tires seat properly on the rims.
A brief clearance check at full steering lock is worthwhile, especially if the EQB 300 has different wheels than expected or any suspension changes. After the first stretch of driving, recheck pressure and look for any signs of rubbing or uneven contact so small issues are caught before they become larger fitment problems.
How often should tires on a 2023 Mercedes-Benz Trucks EQB 300 be inspected?
Tires on a 2023 Mercedes-Benz Trucks EQB 300 should be inspected regularly rather than only when replacement time arrives. Routine checks should include tread condition, visible cuts, sidewall damage, air loss, and any uneven wear pattern that might point to an alignment or suspension concern.
Electric crossovers can accumulate urban miles quietly and smoothly, which sometimes delays attention to tire condition until wear becomes more advanced. A quick visual check and pressure check on a regular schedule helps protect both fitment and drivability. It is also wise to inspect before longer trips or after any wheel or suspension work.
