The 2007 Mercedes-Benz Trucks ML320 sits in the era when luxury SUVs were expected to blend highway comfort, all-weather confidence, and a more substantial road presence than a traditional passenger car. For owners keeping one of these diesel-powered ML320 models in proper driving condition, tire fitment starts with identifying the exact wheel package on the vehicle. The standard ML320 CDI uses 235/65R17 radial tires, while the ML320 CDI w/AMG Sport Pkg. uses 255/50R19 radials. That makes this page less about choosing between bias-ply and radial construction, and more about matching the correct metric size, wheel diameter, and overall stance to the specific sub-model.
Which Tire Size Is Right for The 2007 Mercedes-Benz Trucks ML320
Two tire sizes apply to the 2007 Mercedes-Benz Trucks ML320, and the correct choice depends on the specific sub-model and wheel diameter. The ML320 CDI uses a 17-inch radial tire, while the ML320 CDI w/AMG Sport Pkg. uses a 19-inch radial tire. Before comparing tire choices, confirm whether the vehicle has the standard wheel setup or the AMG Sport Package configuration.
235/65R17 is a metric radial size in which 235 identifies the tire's nominal section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2007 Mercedes-Benz Trucks ML320, this size belongs to the ML320 CDI configuration rather than the AMG Sport Package version. Its dimensions point to a taller-sidewall SUV fitment that suits the vehicle's standard wheel setup. Buyers considering this size should confirm that the vehicle still carries its original 17-inch wheel package before selecting a replacement tire.
255/50R19 is a metric radial size where 255 indicates nominal section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 19 designates the wheel diameter in inches. This size is used on the 2007 Mercedes-Benz Trucks ML320 CDI w/AMG Sport Pkg., making it specific to the sport-oriented wheel package rather than the standard setup. Compared with the 17-inch fitment, the decision here begins with wheel confirmation, not just tread preference. Owners should verify that the SUV still has its 19-inch AMG Sport Package wheels before moving forward with tire selection.
Tire fitment for the 2007 Mercedes-Benz Trucks ML320 varies by sub-model, so identifying the exact configuration matters before anything else. The key difference is wheel diameter, with one version using a 17-inch setup and the other using a 19-inch setup.

Frequently Asked Questions
ML320 tire questions usually come down to sub-model identification, wheel diameter, and understanding the difference between the standard CDI setup and the AMG Sport Package fitment. The FAQs below focus on exact size selection, wheel compatibility, appearance, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2007 Mercedes-Benz Trucks ML320?
The 2007 Mercedes-Benz Trucks ML320 uses two possible tire sizes, depending on sub-model. The ML320 CDI uses 235/65R17, while the ML320 CDI w/AMG Sport Pkg. uses 255/50R19. Both are radial tire sizes, but they are tied to different wheel packages rather than being interchangeable primary fitments across the model range.
Choosing the right size starts with identifying the exact version of the vehicle and confirming the wheel diameter currently on it. A standard CDI and an AMG Sport Package truck do not use the same rim size, so checking the sidewall of the existing tire and verifying the wheel setup is the safest first step before comparing replacement options.
What size rim does a 2007 Mercedes-Benz Trucks ML320 use?
A 2007 Mercedes-Benz Trucks ML320 uses either a 17-inch rim or a 19-inch rim, depending on sub-model. The ML320 CDI uses a 17-inch wheel with 235/65R17 tires, and the ML320 CDI w/AMG Sport Pkg. uses a 19-inch wheel with 255/50R19 tires.
Rim diameter needs to be confirmed before selecting any tire, because a 17-inch tire cannot be mounted on a 19-inch wheel and vice versa. Owners of used ML320s should also keep in mind that wheel changes are common, so the best approach is to verify the actual wheel on the vehicle rather than assuming it still matches the original sub-model configuration.
Do all 2007 Mercedes-Benz Trucks ML320 sub-models use the same tire size?
No. The 2007 Mercedes-Benz Trucks ML320 has sub-model-specific tire sizing. The ML320 CDI uses 235/65R17, while the ML320 CDI w/AMG Sport Pkg. uses 255/50R19. Both fitments are radial, but the difference in wheel diameter means the tire choice changes with the sub-model.
That distinction matters because the first buying decision is not tread style or brand preference, but identifying which version of the ML320 is being fitted. It is also wise to check whether the truck still carries its original wheels, since a previous owner may have changed the package, affecting the size needed for safe and proper fitment.
Choosing the Right Tire
What should I consider when choosing a 235/65R17 or 255/50R19 tire for a 2007 Mercedes-Benz Trucks ML320?
Start with the exact size that matches the sub-model and wheel diameter on the vehicle. A 2007 Mercedes-Benz Trucks ML320 CDI uses 235/65R17, while the ML320 CDI w/AMG Sport Pkg. uses 255/50R19. Since both fitments are radial, the main decision is selecting the correct metric size for the actual wheel package on the truck.
After confirming size, compare replacement tires based on intended use, ride preference, and the vehicle's current setup. A truck that still has factory-style wheels is a different case from one with aftermarket wheels or suspension changes. Clearance, wheel width, and overall tire condition on the vehicle should all be reviewed before settling on a final replacement choice.
How do I choose between the available 2007 Mercedes-Benz Trucks ML320 tire sizes?
The two tire sizes are not alternate choices for the same setup. They correspond to different ML320 configurations: 235/65R17 for the ML320 CDI and 255/50R19 for the ML320 CDI w/AMG Sport Pkg. The correct size is determined by sub-model and wheel diameter, not by personal preference alone.
Once the wheel package is verified, the selection process becomes much simpler because you are comparing tires within the proper size instead of trying to move between two fitments. On a used SUV, checking the sidewall markings on the current tires and measuring the wheel diameter can prevent ordering a tire that matches the model name but not the actual truck.
What tire size should I use for my 2007 Mercedes-Benz Trucks ML320 sub-model?
The 2007 Mercedes-Benz Trucks ML320 CDI uses 235/65R17, and the 2007 Mercedes-Benz Trucks ML320 CDI w/AMG Sport Pkg. uses 255/50R19. Those sizes reflect two different wheel setups, so the right answer depends on the exact sub-model and the wheels currently installed on the vehicle.
Owners should verify both the sub-model designation and the actual wheel diameter before replacing tires. That matters especially on older luxury SUVs, where wheel swaps are common. Matching the tire to the wheel is only part of the job; it also helps to inspect steering clearance and suspension condition so the replacement choice suits the truck's present-day configuration.
Restoration & Appearance
Does correct tire fitment matter for a 2007 Mercedes-Benz Trucks ML320 restoration?
Yes. Correct tire fitment plays an important role in how a 2007 Mercedes-Benz Trucks ML320 sits, drives, and presents itself. The standard ML320 CDI uses 235/65R17, while the ML320 CDI w/AMG Sport Pkg. uses 255/50R19, so preserving the proper sub-model fitment helps maintain the intended look of the vehicle.
Appearance-focused work on a modern collectible SUV still begins with the right wheel-and-tire relationship. A truck restored around its standard wheels should not be treated the same as one retaining its AMG Sport Package setup. Owners pursuing a highly exact presentation may also want to compare the vehicle against original sales literature or marque-specific reference material.
Which tire should I choose for a period-style 2007 Mercedes-Benz Trucks ML320?
A period-style choice starts with the original size format used by the specific ML320 configuration. That means 235/65R17 for the ML320 CDI or 255/50R19 for the ML320 CDI w/AMG Sport Pkg. Both are modern metric radial sizes, so the visual goal is usually preserving the proper stance and wheel-to-tire proportion for the vehicle.
The best approach is to avoid treating the two sizes as cosmetic substitutes for one another. The standard and AMG Sport Package setups create different visual character, and each depends on the wheel package underneath it. Checking the actual wheel diameter and making sure the replacement tire maintains the correct overall presentation will usually matter more than chasing an arbitrary style preference.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mercedes-Benz Trucks ML320?
Yes. Modifications can change tire fitment on a 2007 Mercedes-Benz Trucks ML320 even when the truck originally used either 235/65R17 or 255/50R19. Aftermarket wheels, suspension changes, altered ride height, or body modifications can all affect the relationship between the tire, wheel, and available clearance.
That is why fitment should be checked on the vehicle as it sits today, not just by model name. A previous owner may have changed wheel width, offset, or overall package diameter. Before replacing tires, inspect for rubbing marks, verify steering clearance at full lock, and make sure the wheel diameter matches the tire size being considered.
What should I inspect before driving a 2007 Mercedes-Benz Trucks ML320 on new tires?
Before putting a 2007 Mercedes-Benz Trucks ML320 into regular road use on new tires, inspect the wheels, valve stems, and overall tire condition after installation. It also helps to confirm that the vehicle has the correct 17-inch or 19-inch wheel setup for its tire size and that the tires are seated and inflated properly.
A road-ready check should also include suspension condition, alignment behavior, and basic clearance around fenders and steering components. Uneven wear on the old tires can point to issues that a fresh set will not solve by itself. After the first drives, recheck air pressure and look for any signs of rubbing, vibration, or irregular contact.
How often should tires on a 2007 Mercedes-Benz Trucks ML320 be inspected?
Tires on a 2007 Mercedes-Benz Trucks ML320 should be inspected regularly, especially on a vehicle that may see seasonal or low-mileage use. Routine checks should include tread wear, sidewall cracking, cuts, bulges, and any signs of air loss. Both the 235/65R17 and 255/50R19 fitments deserve the same basic attention.
Inspection becomes even more important as these SUVs age, because storage habits and infrequent driving can hide tire deterioration until the truck is back on the road. Looking over the tires before longer trips, checking pressure consistently, and watching for uneven wear patterns can help catch wheel, alignment, or suspension issues before they become larger fitment problems.
