Mercedes-Benz Trucks ML250 Tires
Mercedes-Benz Trucks ML250 belongs to the modern luxury SUV era, where tire selection matters as much for stance, ride quality, and handling balance as it does for simple fitment. Even within a single model year, Mercedes-Benz Trucks ML250 appears with more than one factory tire size, reflecting different wheel packages rather than one universal setup. That makes tire choice less straightforward than ordering by model name alone, because the same 2015 vehicle can carry different wheel diameters and sidewall proportions. The first thing to verify on a Mercedes-Benz Trucks ML250 is the actual rim diameter on the vehicle, since this model is listed with 18-inch, 19-inch, and 20-inch fitments.
Mercedes-Benz Trucks ML250 Tire Size Guide
Mercedes-Benz Trucks ML250 uses 3 distinct tire sizes across the 2015 to 2015 production span, and the most important fitment fact is that wheel diameter varies within that year. The listed sizes correspond to 18-inch, 19-inch, and 20-inch rims, so confirming which wheel package the vehicle actually has is the first step before choosing a replacement tire. All three sizes use modern metric radial sizing, where the section width is given in millimeters, the aspect ratio is the sidewall height as a percentage of width, and the final number is the rim diameter in inches.
255/50R19 fits 2015 Mercedes-Benz Trucks ML250 applications equipped with the 19-inch wheel package. The code indicates a 255 millimeter section width, a 50 aspect ratio, radial construction, and a 19-inch rim diameter. Choose this size when the vehicle is already fitted with 19-inch wheels and match the replacement to the tire size shown on the vehicle placard and sidewall.
255/55R18 fits 2015 Mercedes-Benz Trucks ML250 applications using the 18-inch wheel package. The code indicates a 255 millimeter section width, a 55 aspect ratio, radial construction, and an 18-inch rim diameter. Choose this size only for ML250 models carrying 18-inch wheels, since the taller sidewall and smaller rim diameter are not interchangeable with the 19-inch or 20-inch options.
265/45R20 fits 2015 Mercedes-Benz Trucks ML250 applications equipped with the 20-inch wheel package. The code indicates a 265 millimeter section width, a 45 aspect ratio, radial construction, and a 20-inch rim diameter. Choose this size when the vehicle has the larger 20-inch wheels and verify wheel width and existing tire markings before replacing a full set.
Buyers with a 2015 Mercedes-Benz Trucks ML250 must identify the specific wheel configuration before selecting a size, because that year includes a rim diameter split between 18-inch, 19-inch, and 20-inch fitments.
Mercedes-Benz Trucks ML250 Tires by Year
Mercedes-Benz Trucks ML250 production changed across 18-inch, 19-inch, and 20-inch wheel fitments in 2015, so confirm which rim diameter the specific vehicle carries before selecting a tire. In 2015, more than two sizes are listed, which points to a wheel-package split rather than one universal size for every ML250.

Frequently Asked Questions
The FAQ below focuses on the key Mercedes-Benz Trucks ML250 fitment questions created by its single-year, multi-size setup, especially how to sort out the 18-inch, 19-inch, and 20-inch wheel options and verify the correct tire before replacement.
Size Basics & Fitment
Mercedes-Benz Trucks ML250 is listed with three tire sizes for 2015: 255/55R18, 255/50R19, and 265/45R20. Those sizes correspond to three different rim diameters: 18 inches, 19 inches, and 20 inches. All three are metric radial sizes, but they are not interchangeable because each one is built around a different wheel diameter and a different sidewall proportion.
The practical step is to match the replacement tire to the wheel package actually fitted to the vehicle, not just the model name. Check the size molded into the current tire sidewall and compare it to the vehicle placard. If the wheels have been changed by a previous owner, use the wheel diameter on the car as the deciding fitment point before selecting tires.
A 2015 Mercedes-Benz Trucks ML250 has 3 tire sizes listed because that model year was offered with different wheel diameters. The three sizes split across 18-inch, 19-inch, and 20-inch rims, so the variation comes from wheel-package differences rather than from one tire fitting every ML250. Each size also carries its own sidewall profile to maintain the intended overall proportions for that wheel setup.
That means year alone is not enough to choose a tire for a 2015 Mercedes-Benz Trucks ML250. You need to identify the actual wheel and tire package on the vehicle before replacing a single tire or a full set. If the vehicle has aftermarket wheels, the current size on the sidewall matters more than assumptions drawn from the original model year.
Mercedes-Benz Trucks ML250 uses more than one rim diameter in the listed fitments. For 2015, the sizes break out to 18-inch rims with 255/55R18, 19-inch rims with 255/50R19, and 20-inch rims with 265/45R20. In metric radial sizing, the final number in the size code is the wheel diameter in inches, so the rim size is built directly into each tire designation.
That makes rim diameter the first fitment check on a Mercedes-Benz Trucks ML250. A tire made for an 18-inch wheel cannot be mounted on a 19-inch or 20-inch rim, even if the width seems close. Verify the wheel diameter on the vehicle itself and then match the replacement tire to the exact size already specified for that wheel package.
Buying the Right Tire
The correct tire size for a 2015 Mercedes-Benz Trucks ML250 is confirmed by the wheel package actually installed on the vehicle. The listed options are 255/55R18, 255/50R19, and 265/45R20, and each one is tied to a different rim diameter. The most reliable identifiers are the size molded on the current tire sidewall and the tire information placard on the vehicle.
Start by checking whether the vehicle has 18-inch, 19-inch, or 20-inch wheels, then match the replacement tire to that exact size. If all four tires are being replaced and the vehicle has had wheel changes in the past, confirm that the wheel diameter and width are appropriate before fitting a new set. That extra check prevents ordering a tire that matches the model but not the wheels.
Maintenance & Longevity
A Mercedes-Benz Trucks ML250 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and long periods of heat exposure. Tire pressure should be kept at the vehicle's specified level during storage so the sidewalls are not left underinflated while the vehicle sits. For a modern SUV with larger wheel packages, maintaining pressure is especially important because low-profile tires can develop flat spotting more readily when neglected.
If the Mercedes-Benz Trucks ML250 will sit for extended periods, move it occasionally to change the tire contact patch or place it on stands if appropriate for the storage plan. Clean the tires with mild soap and water rather than petroleum-based dressings. A quick visual check every few weeks helps catch pressure loss, sidewall cracking, or damage before the vehicle returns to regular use.
Tires on a Mercedes-Benz Trucks ML250 should be inspected at regular intervals even if the vehicle is driven lightly. A monthly inspection is a sensible baseline for checking inflation, tread wear, sidewall condition, punctures, and any signs of uneven wear that could point to alignment or suspension issues. On a vehicle with multiple possible wheel packages, inspection is also a good time to confirm that all four tires match in size and type.
Look closely at the inner and outer shoulders, since low-profile SUV tires can show edge wear before the center tread appears worn. Also check for impact damage from potholes or curbs, especially on the 19-inch and 20-inch fitments. Catching those problems early helps preserve ride quality and reduces the chance of replacing tires prematurely.
Tires on a Mercedes-Benz Trucks ML250 should be replaced when age, structural condition, or visible damage makes continued use questionable, even if tread depth still looks acceptable. Cracking, bulges, repeated pressure loss, vibration that cannot be balanced out, or hardening of the rubber are all stronger warning signs than tread alone on a lightly used collector or secondary vehicle. Age matters because rubber degrades over time whether the vehicle is driven often or not.
A practical approach is to have aging tires evaluated during routine service and to treat calendar age as an important part of replacement planning. If a Mercedes-Benz Trucks ML250 has spent long periods parked outdoors or under low inflation, replace suspect tires sooner rather than later. Safe use depends on the condition of the casing and rubber, not just on how much tread remains.
Safety & Road Use
A Mercedes-Benz Trucks ML250 can be driven safely on public roads when it is fitted with the correct tire size for its wheel package and the tires are in sound condition. The critical point is matching the tire to the proper 18-inch, 19-inch, or 20-inch rim and ensuring the set is evenly matched across the axle, ideally across all four positions. Good condition, proper inflation, and correct fitment matter more than appearance alone.
Before regular road use, inspect the tires for age-related cracking, impact damage, or uneven wear that could affect braking and handling. A Mercedes-Benz Trucks ML250 is sensitive to tire mismatch because changes in overall size can influence ride balance and drivability. If there is any doubt about the condition of an older set, have the tires evaluated before putting the vehicle back into routine service.
Before driving a Mercedes-Benz Trucks ML250, check tire pressure, visible tread and sidewall condition, and whether all four tires are the correct size for the wheel package on the vehicle. Confirm there are no cuts, bulges, punctures, or cords showing, and make sure the tires are wearing evenly. On a model that can carry 18-inch, 19-inch, or 20-inch fitments, size consistency is a basic safety check.
It also helps to look for signs of wheel damage or previous curb impacts, especially on larger-diameter wheel packages with shorter sidewalls. If the steering feels off-center or the vehicle pulls under braking, inspect alignment and suspension rather than assuming the issue is only tire-related. A short walk-around before driving can catch the problems most likely to affect safe road use.
The appropriate speed for a Mercedes-Benz Trucks ML250 depends on the exact tire fitted, its condition, and whether the set matches the proper size for the vehicle's wheel package. Even with modern radial sizing, speed should always reflect real-world condition rather than the model name alone. An older tire or a mismatched set should be treated cautiously regardless of remaining tread.
For practical use, keep speeds conservative until you know the tires are correctly sized, properly inflated, balanced, and free from age-related deterioration. If the Mercedes-Benz Trucks ML250 has recently been returned to service after long storage, begin with lower-speed local driving and evaluate ride, vibration, and braking feel. That approach gives you time to catch fitment or condition issues before extended highway use.
