The 2009 Mercedes-Benz Trucks ML350 sits in the era when luxury SUVs were expected to blend everyday comfort, confident road manners, and year-round utility in one package. Buyers looking at this exact ML350 are usually balancing practical replacement needs with the desire to preserve the vehicle’s original stance and driving character. This model uses a 255/50R19 radial tire, giving it a modern metric fitment on a 19-inch wheel. That keeps the tire decision focused less on decoding vintage sizing and more on choosing the right construction, dimensions, and road-use suitability. Careful wheel confirmation and condition checks still matter, especially on vehicles that may have seen wheel upgrades or suspension changes.
Which Tire Size Is Right for The 2009 Mercedes-Benz Trucks ML350
The 2009 Mercedes-Benz Trucks ML350 uses one primary tire size: 255/50R19. It is a radial tire fitment on a 19-inch rim, and that same size is used across the covered ML350 sub-models here. With fitment consistency already established, the real decision becomes selecting a tire that matches the vehicle’s wheel setup, intended road use, and overall condition rather than sorting through multiple original sizes.
A 255/50R19 size uses modern metric radial sizing: 255 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2009 Mercedes-Benz Trucks ML350, this is a contemporary SUV fitment that supports the vehicle’s intended combination of ride quality, handling, and utility. Because the size itself is straightforward, the important selection factors shift to wheel confirmation, overall tire condition, and matching the replacement tire to the way the vehicle is actually driven. Any ML350 with aftermarket wheels or altered suspension should be checked carefully before replacement.
Tire fitment is straightforward across the covered 2009 Mercedes-Benz Trucks ML350 sub-models because both use the same 255/50R19 radial size. Checking the sub-model still helps confirm that the vehicle remains on the expected wheel setup before choosing a replacement tire.

2009 Mercedes-Benz Trucks ML350 4Matic
The 2009 Mercedes-Benz Trucks ML350 4Matic uses the same 255/50R19 radial tire size as the other covered ML350 configuration. That keeps tire selection centered on proper wheel fit, road-use needs, and confirming the vehicle has not been changed to a different wheel package.
The 2009 Mercedes-Benz Trucks ML350 Base also uses 255/50R19 radial tires. Since the primary size does not change at this sub-model level, the main task is verifying the actual wheels on the vehicle and choosing a tire that suits its present-day use.
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.
Frequently Asked Questions
Owners researching 2009 Mercedes-Benz Trucks ML350 tires usually want clear answers on 255/50R19 fitment, 19-inch wheel compatibility, replacement selection, and the condition checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2009 Mercedes-Benz Trucks ML350?
The 2009 Mercedes-Benz Trucks ML350 uses a 255/50R19 tire size. This is a modern metric radial size, and it is the primary fitment used across the covered ML350 sub-models here, including the Base and 4Matic configurations.
That consistency makes the size question simple, but the vehicle should still be checked before purchase. Confirm that the ML350 is still wearing 19-inch wheels and has not been changed to an aftermarket wheel and tire package, since replacement decisions should follow the wheel setup actually on the vehicle rather than assumption.
What size rim does a 2009 Mercedes-Benz Trucks ML350 use?
The primary tire fitment for the 2009 Mercedes-Benz Trucks ML350 is built around a 19-inch rim. The 255/50R19 size places the 19 at the end of the tire code, which identifies the wheel diameter in inches for that fitment.
Rim diameter is the first wheel measurement to confirm because a tire must match it exactly. It is also wise to verify the actual wheels on the SUV if it has changed hands, since many used luxury SUVs receive wheel upgrades that alter replacement tire needs even when the original vehicle fitment was straightforward.
Do all 2009 Mercedes-Benz Trucks ML350 sub-models use the same tire size?
The covered 2009 Mercedes-Benz Trucks ML350 sub-models use the same tire size. Both the ML350 Base and ML350 4Matic use 255/50R19 radial tires, so there is no split here between those two configurations at the primary fitment level.
That shared fitment removes much of the confusion that can come with sub-model-based tire shopping. Even so, buyers should still confirm the wheels currently on the vehicle, because prior owners sometimes install different diameters or widths, and those changes can affect what tire size should be used going forward.
Choosing the Right Tire
What should I consider when choosing a 255/50R19 tire for a 2009 Mercedes-Benz Trucks ML350?
Start with the correct size and construction: the 2009 Mercedes-Benz Trucks ML350 uses a 255/50R19 radial tire. Since there is one primary size across the covered sub-models, the main selection factors are matching the tire to the vehicle’s wheel setup, expected use, and the condition of the ML350 itself.
A practical choice should account for whether the SUV is used mainly for commuting, highway travel, or occasional collector-style use. It also helps to inspect the current tires and wheels for uneven wear, damage, and prior modifications, because those clues often reveal alignment, suspension, or wheel-fit issues that matter before replacement.
How do I choose between the available 255/50R19 tires for a 2009 Mercedes-Benz Trucks ML350?
Choosing between 255/50R19 tires for a 2009 Mercedes-Benz Trucks ML350 starts with staying in the correct size and radial construction. From there, the meaningful differences usually come down to how the vehicle is driven, the wheel setup it currently has, and whether the goal is a standard road-going replacement or a more appearance-conscious selection.
It is helpful to compare the tire against the ML350’s present condition rather than shopping by size alone. A vehicle with altered wheels, uneven tread wear, or suspension changes may need additional fitment review first, while a well-maintained example on stock-style 19-inch wheels can usually be evaluated more simply.
What rim-fitment details matter when choosing tires for a 2009 Mercedes-Benz Trucks ML350?
The most important rim-fitment detail is wheel diameter, because the 2009 Mercedes-Benz Trucks ML350’s primary tire size is 255/50R19 and therefore requires a 19-inch wheel. Correct wheel width and the overall wheel setup also matter, even when the tire size itself is already known.
A careful check is especially worthwhile on a used SUV. Wheel changes, offset differences, and suspension alterations can all affect how a replacement tire sits in the wheel opening and how much clearance remains during steering and suspension movement, so fitment should be confirmed on the actual vehicle before final selection.
Restoration & Appearance
Does correct tire fitment matter for a 2009 Mercedes-Benz Trucks ML350 restoration?
Yes, correct tire fitment still matters on a 2009 Mercedes-Benz Trucks ML350 restoration or refurbishment project. Using the proper 255/50R19 size helps preserve the vehicle’s intended stance and keeps the appearance in line with the original 19-inch wheel fitment used on the covered ML350 configurations.
Appearance is only part of the picture. Returning the SUV to the correct size also provides a more reliable starting point for checking wheel clearance, overall condition, and drivability, especially if the vehicle has spent time on oversized wheels or mismatched replacement tires during its later used-vehicle life.
Which tire should I choose for a period-appropriate 2009 Mercedes-Benz Trucks ML350?
A period-appropriate starting point for a 2009 Mercedes-Benz Trucks ML350 is the original-size format itself: 255/50R19 radial on a 19-inch wheel. Because this is a modern SUV fitment rather than a vintage bias-ply application, staying with the correct size and overall proportions does more for the vehicle’s appearance than chasing an older-style construction.
The best visual result usually comes from a tire that complements the ML350’s wheel design and maintains the proper stance. Any SUV that has been lowered, lifted, or fitted with non-original wheel diameters should be reviewed carefully, since those changes can alter the way a replacement tire looks and fits.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Mercedes-Benz Trucks ML350?
Yes, modifications can affect tire fitment on a 2009 Mercedes-Benz Trucks ML350 even though the primary size is a straightforward 255/50R19. Changes such as aftermarket wheels, altered wheel offsets, suspension lowering, ride-height changes, or body modifications can all influence what will work properly on the vehicle.
A modified ML350 should be checked at the wheel itself rather than relying on original-size assumptions. Wheel diameter, width, and clearance at full steering lock are especially important, and visible rubbing marks, uneven wear, or limited clearance in the fender opening are signs that the current setup needs closer review before replacement.
What should I inspect before driving a 2009 Mercedes-Benz Trucks ML350 on new tires?
Before putting a 2009 Mercedes-Benz Trucks ML350 back into regular use on new tires, inspect the wheels, valve stems, and existing suspension condition along with the replacement size itself. The correct baseline fitment is 255/50R19, but roadworthiness also depends on the rest of the vehicle supporting that tire properly.
Pay close attention to alignment-related wear, steering response, air retention, and any signs of rubbing or contact inside the wheel opening. It also helps to check for cracked rubber components, worn shocks, or sagging suspension parts, since those issues can shorten tire life quickly even when the new tires are the correct size.
How often should tires on a 2009 Mercedes-Benz Trucks ML350 be inspected?
Tires on a 2009 Mercedes-Benz Trucks ML350 should be inspected regularly, not just when replacement time arrives. A 255/50R19 radial tire can look acceptable at a glance while still developing uneven wear, pressure loss, sidewall damage, or age-related deterioration that affects how the SUV drives.
A consistent routine is more useful than waiting for an obvious problem. Checking tread condition, sidewalls, and air pressure on a regular basis helps catch issues early, and it becomes even more important if the ML350 is driven infrequently, stored for stretches, or fitted with wheels and suspension components that differ from stock.
