The 2008 Mercedes-Benz Trucks ML350 sits in the era when luxury SUVs were expected to balance all-weather confidence, everyday comfort, and a more athletic road feel than earlier utility vehicles. For owners keeping one on the road today, tire fitment is less about sorting through multiple factory-era sizing systems and more about getting the correct modern radial setup back under the vehicle. The 2008 Mercedes-Benz Trucks ML350 uses a 255/50R19 radial tire, and the covered 4Matic fitment follows that same size. That makes the main decision one of tire selection, wheel confirmation, and overall condition rather than deciphering several vintage fitments before road use.
Which Tire Size Is Right for The 2008 Mercedes-Benz Trucks ML350
The 2008 Mercedes-Benz Trucks ML350 uses one primary tire size: 255/50R19. This is a modern metric radial fitment on a 19-inch rim, and the covered 4Matic sub-model uses the same size, so the decision is less about choosing between fitments and more about confirming the wheel setup and selecting the right tire within that specification.
255/50R19 is a modern metric radial size in which 255 identifies the nominal section width in millimeters, 50 is the aspect ratio, R designates radial construction, and 19 is the wheel diameter in inches. On the 2008 Mercedes-Benz Trucks ML350, this format reflects a contemporary SUV fitment rather than an older bias-ply or alphanumeric system. The key buying factors are proper wheel diameter, compatibility with the existing wheel width and vehicle setup, and the condition of the suspension and alignment. It is the right starting point for restoring correct-size road manners on an unmodified ML350.
Tire fitment is straightforward for the covered 2008 Mercedes-Benz Trucks ML350 sub-model. The 4Matic version uses the same primary size, so the main task is confirming that the vehicle still has the proper 19-inch wheel setup before choosing a replacement tire.

Frequently Asked Questions
These FAQs focus on 2008 Mercedes-Benz Trucks ML350 tire size, 19-inch rim fitment, sub-model consistency, choosing the right 255/50R19 tire, and the checks worth making before putting a collector-aged luxury SUV back into regular road use.
Tire Size & Fitment
What tire size fits a 2008 Mercedes-Benz Trucks ML350?
The 2008 Mercedes-Benz Trucks ML350 uses a 255/50R19 tire size. That is a modern metric radial fitment, with 255 indicating nominal section width in millimeters, 50 indicating aspect ratio, and 19 indicating the wheel diameter in inches.
Using the correct size starts with confirming that the vehicle still has its 19-inch wheels and has not been changed to an aftermarket setup. If the SUV has replacement wheels, suspension changes, or uneven tire wear, it is worth checking wheel width, clearance, and alignment before choosing a new set of 255/50R19 tires.
What size rim does a 2008 Mercedes-Benz Trucks ML350 use?
The primary tire fitment for the 2008 Mercedes-Benz Trucks ML350 is built around a 19-inch rim. That rim diameter is reflected directly in the 255/50R19 size, where the final number identifies the wheel diameter the tire is designed to mount on.
Rim diameter should be confirmed before ordering tires, especially on an SUV that may have seen wheel upgrades over the years. A 19-inch tire should only be matched to a 19-inch wheel, and it also helps to verify wheel width and overall condition so the new tire works properly with the vehicle's existing setup.
Do all 2008 Mercedes-Benz Trucks ML350 sub-models use the same tire size?
The covered 2008 Mercedes-Benz Trucks ML350 sub-model fitment is consistent. The ML350 4Matic uses the same 255/50R19 radial tire size, so there is no separate alternate size to sort through within the covered fitment.
That consistency makes tire shopping simpler, but the vehicle should still be checked as it sits today. SUVs in this age range are often found with replacement wheels or non-original tire sizes, so matching the correct 255/50R19 size to the actual wheel on the vehicle remains an important final step.
Choosing the Right Tire
What should I consider when choosing a 255/50R19 tire for a 2008 Mercedes-Benz Trucks ML350?
Start with the correct size and construction. The 2008 Mercedes-Benz Trucks ML350 uses a 255/50R19 radial tire, so the first priority is staying within that fitment and confirming the tire matches the vehicle's 19-inch wheel setup.
After size is confirmed, compare the tires in terms of how the ML350 is actually used. Daily road use, fair-weather driving, long parked periods, and the condition of the wheels and suspension all matter. A properly sized radial tire will only perform as intended if alignment, air pressure, and wheel condition are also in good order.
How do I choose between the available 255/50R19 tires for a 2008 Mercedes-Benz Trucks ML350?
The best comparison point is whether each tire keeps the vehicle within its correct 255/50R19 radial fitment. Once that is settled, the differences that matter most are wheel compatibility, intended road use, and whether the vehicle remains stock or has been altered over time.
A lightly used ML350 that sees weekend driving may call for a different emphasis than one used regularly in changing weather. It also helps to inspect current wear patterns before replacing tires, since unusual wear can point to alignment or suspension issues that should be corrected before installing another set in the same size.
What rim-fitment details should I compare when choosing 2008 Mercedes-Benz Trucks ML350 tires?
The first rim-fitment detail is diameter, and the 2008 Mercedes-Benz Trucks ML350 uses a 19-inch wheel with its 255/50R19 tire size. The next step is making sure the wheel itself is appropriate for that tire and is free from damage, corrosion, or previous repair issues.
Wheel width and the actual wheel installed on the vehicle matter just as much as diameter, especially if the SUV has aftermarket wheels. A tire can be the right nominal size yet still need a closer look at wheel condition, clearance, and setup before installation, particularly on a heavier vehicle used for everyday road service.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Mercedes-Benz Trucks ML350?
A period-style approach for a 2008 Mercedes-Benz Trucks ML350 starts by keeping the correct 255/50R19 radial size in place. Because this ML350 already uses a modern metric radial fitment, preserving the intended look usually means avoiding off-size replacements that visually change the stance or sidewall profile.
Owners aiming for a clean, era-appropriate presentation should also confirm that the wheels remain true to the vehicle's current setup and that ride height has not been altered. On a newer collector vehicle, accurate size and proper overall proportion often matter more to appearance than chasing a dramatically different tire style.
Does correct tire fitment matter for a 2008 Mercedes-Benz Trucks ML350 restoration?
Correct tire fitment matters because it affects both appearance and function on a 2008 Mercedes-Benz Trucks ML350. Staying with the proper 255/50R19 radial size helps preserve the vehicle's intended proportions while also supporting normal wheel, steering, and road-use behavior.
Restoration-minded owners should treat tire size as part of the overall presentation, not just a maintenance item. Even on a modern-era SUV, an incorrect size can change how the vehicle sits and can complicate clearance or handling. Checking the actual wheels on the vehicle is especially important before trying to return it to a more original-looking stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mercedes-Benz Trucks ML350?
Yes, modifications can affect tire fitment on a 2008 Mercedes-Benz Trucks ML350 even when the target tire size remains 255/50R19. Wheel changes, altered offsets, suspension lowering, and other non-stock changes can influence clearance at the fender, suspension, and steering components.
That is why the actual vehicle should be checked before replacing tires. A stock-size radial may still need closer review if the ML350 has aftermarket wheels or suspension work, and uneven wear on the current tires can also signal that alignment or suspension condition should be addressed along with the replacement.
What should I inspect before driving a 2008 Mercedes-Benz Trucks ML350 on new tires?
Before road use, inspect wheel condition, tire pressure, lug hardware, and the basic state of the suspension and steering. It also helps to check for old alignment problems, because a fresh set of 255/50R19 tires can wear quickly if the ML350 already has uneven camber, toe, or worn components.
A careful visual inspection should include the current wheels for bends or damage and the surrounding suspension for looseness or leakage. On an older luxury SUV that may have spent time parked, seals, bushings, and air retention deserve attention as well, since tire replacement alone does not correct neglected chassis issues.
How often should tires on a 2008 Mercedes-Benz Trucks ML350 be inspected?
Tires on a 2008 Mercedes-Benz Trucks ML350 should be inspected regularly, especially if the vehicle is driven infrequently or stored for long periods. Check for air loss, sidewall cracking, cuts, bulges, tread wear, and any signs that the 255/50R19 tires are wearing differently from one side of the vehicle to the other.
Low-use vehicles can age their tires even when tread still looks usable, so condition matters as much as mileage. A quick inspection before routine driving and a more thorough look before longer trips is a sensible habit, particularly on an SUV where weight, storage time, and suspension wear can all influence tire condition.
