The 1998 Mercedes-Benz Trucks ML320 came from the first wave of luxury SUVs that blended everyday utility with the road manners buyers expected from a premium German brand. It occupies an important place in the early modern SUV era, where ride quality, all-season usability, and a confident stance all mattered as much as cargo space. For this exact ML320 fitment, the primary tire size is 255/65R16 in radial construction. That keeps the tire decision focused less on decoding multiple factory sizes and more on choosing the right tire within the correct dimensions for appearance, road use, and wheel compatibility. For original-type fitment, confirming the 16-inch wheel setup is the key first step.
Which Tire Size Is Right for The 1998 Mercedes-Benz Trucks ML320
The 1998 Mercedes-Benz Trucks ML320 uses one primary tire size: 255/65R16, a radial tire fitted to a 16-inch rim. That same size applies to the covered Base sub-model, so the main decision is not between multiple fitments, but between tire choices within the proper size and confirming that the vehicle still retains its correct wheel setup.
255/65R16 is a metric radial size in which 255 refers to the nominal section width in millimeters, 65 is the aspect ratio, R designates radial construction, and 16 identifies the rim diameter in inches. On the 1998 Mercedes-Benz Trucks ML320, this is the primary fitment and it matches the vehicle's modern SUV-era tire format rather than an older bias-ply sizing system. The size delivers a useful balance of width and sidewall profile for an ML320 with its original-type wheel diameter. Choosing this size starts with preserving the intended fitment envelope before comparing individual tire styles or vehicle condition.
Fitment is straightforward for the covered 1998 Mercedes-Benz Trucks ML320 sub-models because the same primary tire size is used throughout. Checking the exact sub-model still matters, but this is a case where tire selection stays centered on the correct 255/65R16 size and 16-inch wheel diameter.

Frequently Asked Questions
These FAQs focus on the exact tire fitment for the 1998 Mercedes-Benz Trucks ML320, including 255/65R16 sizing, 16-inch rim considerations, tire selection, restoration-minded fitment questions, and the basic checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 1998 Mercedes-Benz Trucks ML320?
The 1998 Mercedes-Benz Trucks ML320 uses a 255/65R16 radial tire size. That is the primary fitment for this vehicle, and it is the size used on the covered ML320 Base sub-model as well.
Using the correct size matters because it keeps the vehicle within its intended fitment range for wheel diameter and overall tire proportions. A buyer should still confirm that the SUV has its proper 16-inch wheels and has not been changed to a different wheel and tire package over the years before choosing a replacement.
What size rim does a 1998 Mercedes-Benz Trucks ML320 use?
The 1998 Mercedes-Benz Trucks ML320 uses a 16-inch rim with its primary 255/65R16 tire size. In tire sizing terms, the final number in 255/65R16 identifies the wheel diameter, so the tire is built for a 16-inch wheel.
Wheel diameter is the first fitment point to confirm before purchasing tires, especially on older SUVs that may have received aftermarket wheels. Checking the actual wheel on the vehicle helps avoid ordering the correct tire size for the wrong wheel package and keeps the tire search focused on the proper fitment.
Does the 1998 Mercedes-Benz Trucks ML320 Base use the same tire size?
Yes. The 1998 Mercedes-Benz Trucks ML320 Base uses the same 255/65R16 radial tire size as the main vehicle fitment. That makes tire selection more straightforward than on vehicles that split fitment across several trims or wheel packages.
Even with shared fitment, it is still smart to inspect the vehicle itself before replacing tires. An ML320 that has been modified with different wheels, altered suspension height, or non-original tire sizing should be measured against its current setup so the next tire choice matches both the vehicle and the wheel actually in use.
Choosing the Right Tire
What should I consider when choosing a 255/65R16 tire for a 1998 Mercedes-Benz Trucks ML320?
Start with the correct size, which is 255/65R16 on a 16-inch wheel. Since this ML320 uses a modern metric radial fitment, the key is staying within the proper sizing format and choosing a tire that matches how the vehicle will be driven and presented.
A practical selection process includes confirming the wheel diameter, checking the actual wheel width, and thinking about whether the vehicle is a regular driver or a lower-mile collector SUV. Tire age, suspension condition, and any past wheel changes also matter, because they can affect how well a new tire suits the current vehicle setup.
How do I choose between available 255/65R16 tires for a 1998 Mercedes-Benz Trucks ML320?
The first filter is simple: stay with the proper 255/65R16 size for the 1998 Mercedes-Benz Trucks ML320. After that, the comparison becomes one of overall tire character, including how closely a tire matches the vehicle's intended use and whether the ML320 is being kept in a more original-style presentation.
Looking beyond the size code helps narrow the field. Wheel compatibility, tread style, ride expectations, and how the SUV is stored and driven can all influence the right choice. A vehicle that sees regular road use may call for a different emphasis than one kept primarily for occasional driving and preservation.
What rim-width specifications should I compare when choosing 1998 Mercedes-Benz Trucks ML320 tires?
Rim width should be checked alongside the 255/65R16 size because a tire must suit both the wheel diameter and the actual wheel width. Even when the tire size is correct for the 1998 Mercedes-Benz Trucks ML320, the wheel itself still needs to fall within the tire manufacturer's approved fitment range.
That becomes especially important if the ML320 has replacement wheels or a previous owner changed the setup. Measuring the wheel and comparing it to the tire's approved width range helps prevent mounting issues and supports proper tire shape, clearance, and road behavior without assuming every 16-inch wheel is the same.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Mercedes-Benz Trucks ML320?
A period-style approach for a 1998 Mercedes-Benz Trucks ML320 begins with the correct 255/65R16 radial size on a 16-inch wheel. Because this is a late-1990s luxury SUV, keeping the proper modern metric radial format is an important part of preserving the vehicle's original visual stance and overall fitment character.
Appearance-minded buyers should pay close attention to overall tire proportions and how the tire sits on the wheel, rather than treating any 16-inch SUV tire as visually equivalent. When originality matters beyond basic size, period brochures, marque resources, and surviving reference vehicles can help guide the finer details of a restoration-oriented selection.
Does correct tire fitment matter for a 1998 Mercedes-Benz Trucks ML320 restoration?
Yes, correct tire fitment matters because the 255/65R16 size helps preserve the intended proportions of the 1998 Mercedes-Benz Trucks ML320. A restoration can look noticeably different when the tire width, sidewall profile, or wheel diameter drifts away from the original-style fitment range.
Proper fitment also affects more than appearance. Tire size influences how the SUV sits, how much wheelwell space it fills, and how naturally the wheel-and-tire package suits the body. On a restoration-minded vehicle, confirming the actual wheels and avoiding mismatched substitute sizes helps maintain a more coherent finished result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Mercedes-Benz Trucks ML320?
Yes. Modifications can change how a 255/65R16 tire works on a 1998 Mercedes-Benz Trucks ML320, even when that size is correct for the original setup. Aftermarket wheels, wheel offset changes, suspension alterations, or body modifications can all influence clearance and how the tire sits within the wheel opening.
A modified ML320 should be checked as it currently sits, not just by original catalog fitment. Measuring the wheel diameter and width, checking steering clearance, and looking for any rubbing points at full lock or suspension movement helps confirm that the intended tire choice matches the SUV's present configuration.
What should I inspect before driving a 1998 Mercedes-Benz Trucks ML320 on new tires?
Before road use, inspect the wheels for damage, confirm the tire size matches the wheel, and make sure the tires are mounted and inflated properly. It is also wise to look over the suspension, steering components, and alignment condition so the new 255/65R16 tires are not immediately compromised by existing mechanical issues.
A short initial test drive can reveal vibration, pulling, or clearance concerns that are easier to correct early. Tire pressure should be rechecked after installation, and the vehicle should be inspected for any contact marks inside the fenders or around the suspension, especially if wheel or ride-height changes are part of its history.
How should 255/65R16 tires on a collector 1998 Mercedes-Benz Trucks ML320 be maintained?
Collector-use tires on a 1998 Mercedes-Benz Trucks ML320 should be inspected regularly for air loss, tread wear, sidewall cracking, cuts, and bulges, even if the SUV is driven sparingly. Low annual mileage does not stop tires from aging, so condition matters just as much as tread depth on a preserved vehicle.
Good storage habits also help extend tire life. Keeping the ML320 away from prolonged sunlight, moisture, and ozone-producing equipment can reduce premature deterioration, while periodic pressure checks help the tires hold their shape. An older collector SUV benefits from routine visual inspection before every outing, not just during major service intervals.
