The 2008 Mercedes-Benz Trucks ML320 sits in the era when luxury SUVs were expected to balance daily road comfort, all-weather confidence, and the substantial stance buyers wanted from a premium utility vehicle. For owners keeping one on the road today, tire choice is less about sorting through multiple original sizes and more about selecting the right version of the correct fitment. The 2008 Mercedes-Benz Trucks ML320 uses a 255/50R19 radial tire on a 19-inch rim. That keeps the decision centered on tire type, overall road-use priorities, and wheel compatibility rather than vintage bias-ply concerns. A careful match matters most if the vehicle has replacement wheels, suspension changes, or restoration-minded appearance goals.
Which Tire Size Is Right for The 2008 Mercedes-Benz Trucks ML320
The 2008 Mercedes-Benz Trucks ML320 uses one primary tire size: 255/50R19, and it is a radial fitment for a 19-inch rim. The covered ML320 CDI sub-model uses the same size, so the main decision is not which primary size fits, but whether your wheels remain true to spec and which 255/50R19 tire best suits how the vehicle is driven and maintained.
A 255/50R19 size uses a 255-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2008 Mercedes-Benz Trucks ML320, this is the primary modern radial fitment, so buyers are working within a contemporary sizing format rather than an older bias-ply or alphanumeric system. That makes the selection process more familiar, but wheel condition, actual rim size, and overall clearance still matter. This size is the right starting point for maintaining the intended stance and road manners of the ML320.
Fitment is straightforward for the covered 2008 Mercedes-Benz Trucks ML320 sub-model. The ML320 CDI uses the same primary tire size, so the key step is confirming the vehicle still has the proper 19-inch wheel setup before choosing a replacement tire.

Frequently Asked Questions
Owners of a 2008 Mercedes-Benz Trucks ML320 usually want quick answers on the correct 255/50R19 size, 19-inch rim fitment, wheel changes, and the basic checks that matter before putting the vehicle back into regular road use.
Tire Size & Fitment
What tire size fits a 2008 Mercedes-Benz Trucks ML320?
The 2008 Mercedes-Benz Trucks ML320 uses a 255/50R19 tire size. This is a radial tire format, and it is paired with a 19-inch rim diameter for the covered fitment.
That makes 255/50R19 the first specification to confirm when replacing tires on an ML320. It is still worth checking the actual wheels on the vehicle, especially if it has had wheel swaps or previous owner modifications, because matching the correct size code alone does not rule out differences in wheel width, offset, or clearance.
What size rim does a 2008 Mercedes-Benz Trucks ML320 use?
The 2008 Mercedes-Benz Trucks ML320 uses a 19-inch rim with its 255/50R19 tire fitment. The tire size itself confirms that rim diameter through the final number in the size code.
Rim diameter is one of the most important checks before mounting replacement tires. A tire built for a 19-inch wheel cannot be safely mounted on a different rim diameter, and an ML320 with aftermarket wheels may also have width or offset differences that affect how the tire sits in the wheel opening and how it clears steering and suspension components.
Does the 2008 Mercedes-Benz Trucks ML320 CDI use the same tire size?
Yes. The covered 2008 Mercedes-Benz Trucks ML320 CDI uses the same 255/50R19 radial tire size as the core ML320 fitment. That keeps tire selection simple at the sub-model level.
Even with shared fitment, it is smart to inspect the actual wheel and tire package currently on the vehicle before ordering replacements. An ML320 CDI that has seen wheel upgrades, suspension changes, or mixed replacement history may no longer match the original-style setup, so confirming the mounted wheel diameter and the existing tire markings helps avoid fitment surprises.
Choosing the Right Tire
What should I consider when choosing a 255/50R19 tire for a 2008 Mercedes-Benz Trucks ML320?
Start with the correct primary fitment: 255/50R19 on a 19-inch rim. Since the 2008 Mercedes-Benz Trucks ML320 uses a modern radial size, the main selection factors are matching the tire to the existing wheel setup and choosing a replacement that suits the vehicle's current use.
A careful buyer will also look at how the ML320 is driven today. Daily road use, occasional highway trips, long periods of storage, and any wheel changes can all influence what matters most. It also helps to inspect current tire wear patterns, because uneven wear may point to alignment, suspension, or inflation issues that should be addressed before mounting a new set.
How do I choose between available 255/50R19 tires for a 2008 Mercedes-Benz Trucks ML320?
The first filter is simple: stay with the correct 255/50R19 size and confirm the vehicle still uses the proper 19-inch wheels. From there, the decision becomes one of intended use, wheel compatibility, and the overall condition of the vehicle's chassis and suspension.
Comparing replacement tires makes more sense when the rest of the setup is known. An ML320 with original-style wheels may call for a different approach than one with aftermarket wheels or a changed ride height. Looking at tread wear, ride expectations, and how long the vehicle sits between drives will help narrow the field more effectively than focusing on size alone.
What rim-fitment details should I compare when choosing tires for a 2008 Mercedes-Benz Trucks ML320?
The key rim-fitment detail is the 19-inch wheel diameter required by the 255/50R19 tire size. Beyond diameter, the actual wheel width and offset on the vehicle also affect how the tire mounts and how it sits within the fender and suspension space.
That matters most on vehicles that may have had wheel changes over time. A tire in the correct nominal size can still create issues if the wheel is not well matched to it. Verifying wheel measurements, checking inner and outer clearance, and inspecting for any rubbing marks gives a much clearer picture before committing to a replacement tire.
Restoration & Appearance
Does correct tire fitment matter for a 2008 Mercedes-Benz Trucks ML320 restoration?
Yes. Even on a newer collector-interest vehicle such as the 2008 Mercedes-Benz Trucks ML320, correct tire fitment affects stance, wheel-to-tire proportion, and the way the vehicle presents overall. The proper starting point is the 255/50R19 radial size on a 19-inch rim.
Restoration-minded owners should verify what is actually on the vehicle today before replacing tires. Many SUVs pick up wheel changes during their lives, and those changes can alter the look as much as the fitment. Keeping the correct size relationship helps preserve a more authentic appearance, even when the goal is a clean, road-ready presentation rather than strict originality.
Which tire should I choose for a period-style 2008 Mercedes-Benz Trucks ML320?
A period-style approach begins with the correct 255/50R19 radial size, since that preserves the basic proportions intended for the 2008 Mercedes-Benz Trucks ML320. On this vehicle, appearance is shaped more by maintaining the proper modern fitment than by choosing between vintage construction types.
The most important step is making sure the vehicle still wears the appropriate 19-inch wheel setup. If the ML320 has oversized replacement wheels or a nonstandard suspension stance, even a quality tire can look out of character. Keeping the right size and overall wheel package usually does more for a clean, era-appropriate appearance than chasing cosmetic details alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mercedes-Benz Trucks ML320?
Yes. Modifications can change how a 255/50R19 tire fits on a 2008 Mercedes-Benz Trucks ML320, even when the tire size itself is correct. Wheel width, wheel offset, suspension height, and brake or body changes can all influence available space around the tire.
That is why the current setup should be checked rather than assumed. An ML320 with aftermarket wheels may place the tire farther inward or outward than expected, which can affect steering clearance and fender room. Looking at the full wheel-and-suspension package before replacing tires helps prevent rubbing, uneven wear, and appearance issues.
What should I inspect before driving a 2008 Mercedes-Benz Trucks ML320 on new tires?
Before road use, inspect the wheels for damage, confirm the mounted tires are the correct 255/50R19 size, and make sure the tires are inflated properly for the vehicle's needs. It is also wise to check for alignment problems, loose suspension parts, and any signs of brake or hub issues.
A fresh set of tires cannot compensate for worn chassis components. An ML320 that pulls, vibrates, or shows uneven old-tire wear may need attention before the new tires can work as intended. A short inspection drive after installation, along with a recheck for clearance and air pressure, helps confirm everything is settling in correctly.
How often should tires on a 2008 Mercedes-Benz Trucks ML320 be inspected?
Tires on a 2008 Mercedes-Benz Trucks ML320 should be inspected regularly, not just when tread looks low. Pressure, visible cracking, cuts, bulges, uneven wear, and slow air loss are all worth checking, especially on a vehicle that may alternate between frequent use and long parked periods.
Routine inspections matter because aging and storage conditions can affect tires even when mileage stays modest. Looking over the tires before longer drives, after seasonal temperature swings, and any time ride quality changes can help catch problems early. Keeping an eye on wear patterns also helps reveal alignment or suspension concerns before they shorten tire life.
