The 2000 Mercedes-Benz Trucks ML320 came from the first-generation M-Class era, when Mercedes-Benz brought luxury-brand engineering into the midsize SUV market with a vehicle built for everyday road use and light utility duty. That combination makes tire choice less about chasing novelty and more about preserving the balance the ML320 was designed around. This model uses a 255/65R16 radial tire on a 16-inch rim. For most owners, the decision centers on choosing the right tire within that size and confirming the vehicle still has its original wheel setup. A careful match supports ride quality, appearance, and predictable fitment on a two-decade-old SUV.
Which Tire Size Is Right for The 2000 Mercedes-Benz Trucks ML320
The 2000 Mercedes-Benz Trucks ML320 uses one primary tire size: 255/65R16, and it is a radial fitment for a 16-inch rim. The covered sub-model shares that same size, so the main decision is not which primary size fits, but which 255/65R16 tire best suits the vehicle's current wheel setup, use, and overall condition.
A 255/65R16 tire uses a metric sizing system: 255 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. Radial construction is the primary fitment for the 2000 Mercedes-Benz Trucks ML320 and matches the vehicle's modern SUV design and road-oriented character. The practical focus with this size is selecting a tire that matches the existing wheel diameter and overall vehicle setup. It is also wise to confirm the ML320 has not been changed to a different wheel package before settling on a replacement.
Sub-model fitment is straightforward here because the covered ML320 configuration uses the same primary tire size. Checking the exact sub-model still helps confirm that a Base model remains on the expected 16-inch wheel setup before choosing a replacement tire.

Frequently Asked Questions
These FAQs focus on 2000 Mercedes-Benz Trucks ML320 tire size, 16-inch rim fitment, choosing the right 255/65R16 radial tire, and the checks that matter before putting an older M-Class back into regular road use.
Tire Size & Fitment
What tire size fits a 2000 Mercedes-Benz Trucks ML320?
The 2000 Mercedes-Benz Trucks ML320 uses a 255/65R16 tire size. That is a radial tire fitment, and it is the primary size associated with this model for the covered configuration.
That means the first step is confirming the ML320 still has 16-inch wheels and has not been switched to a different wheel and tire package over the years. Once the wheel setup is confirmed, the decision moves to selecting the right 255/65R16 tire for the vehicle's condition, use, and overall presentation.
What size rim does a 2000 Mercedes-Benz Trucks ML320 use?
The 2000 Mercedes-Benz Trucks ML320 uses a 16-inch rim with its primary 255/65R16 tire size. In that size code, the final number, 16, is the wheel diameter in inches.
Rim diameter is critical because a 16-inch tire must be mounted on a 16-inch wheel. Before replacing tires, check the actual wheels on the vehicle, especially if it has changed owners or has been customized, since a different wheel diameter changes the tire size required.
Does the 2000 Mercedes-Benz Trucks ML320 Base use the same tire size?
Yes. The 2000 Mercedes-Benz Trucks ML320 Base uses the same 255/65R16 radial tire size. That keeps fitment simple within the covered sub-model range for this vehicle.
Even with shared fitment, it is still smart to inspect the actual wheel and tire combination on the SUV before ordering replacements. Older vehicles are often fitted with aftermarket wheels, and verifying the current setup helps avoid choosing a tire size that matches the model on paper but not the vehicle in front of you.
Choosing the Right Tire
What should I consider when choosing a 255/65R16 tire for a 2000 Mercedes-Benz Trucks ML320?
Start with the correct primary size, which is 255/65R16, and confirm the vehicle still uses the original 16-inch wheel diameter. Since this ML320 uses a radial fitment, the goal is choosing a tire in that size that suits the SUV's intended road use and present-day condition.
Beyond size, pay attention to how the vehicle is actually used, whether it is driven regularly, kept as a clean older SUV, or sees occasional long trips. Wheel condition, suspension wear, alignment condition, and any previous modifications can all influence how well a new set of tires works once installed.
How do I choose between the available 255/65R16 tires for a 2000 Mercedes-Benz Trucks ML320?
The main comparison point is not the basic fitment, since 255/65R16 is the established size, but how each tire suits the vehicle's setup and purpose. On an older luxury SUV like the ML320, buyers often weigh ride character, appearance, and compatibility with the existing wheels.
A careful selection starts with confirming the wheels are true 16-inch units in good condition and that the vehicle has no clearance issues from previous changes. It also helps to inspect the suspension and steering components, because worn parts can affect how any replacement tire feels and wears in service.
Why is it important to keep the correct tire size on a 2000 Mercedes-Benz Trucks ML320?
Keeping the correct 255/65R16 size on a 2000 Mercedes-Benz Trucks ML320 helps preserve the fitment relationship between the tire, the 16-inch wheel, and the vehicle's chassis. This size is the baseline for choosing a replacement tire for the covered ML320 configuration.
Moving away from the established size without a complete fitment review can introduce clearance, wheel-compatibility, or overall setup issues. On an SUV that may already have aging suspension parts or prior modifications, staying with the proper size is the simplest way to begin with a sound and predictable tire selection.
Restoration & Appearance
Which tire should I choose for a period-style 2000 Mercedes-Benz Trucks ML320?
A period-style approach starts by staying with the primary 255/65R16 size used on the 2000 Mercedes-Benz Trucks ML320. Keeping the correct size on the correct 16-inch wheel helps maintain the vehicle's intended proportions and avoids giving the first-generation M-Class an overly altered look.
For an appearance-focused ML320, the best choice is usually the tire that respects the original sizing rather than chasing a dramatically different profile. It is also worth confirming the SUV has not been changed to aftermarket wheels, since the right visual result depends as much on the wheel-and-tire relationship as the tire size itself.
Does correct tire fitment matter for a 2000 Mercedes-Benz Trucks ML320 restoration?
Yes, correct tire fitment matters because the 255/65R16 size helps preserve the stance and visual balance expected on a 2000 Mercedes-Benz Trucks ML320. Even on a newer collector-era SUV, tire size has a noticeable effect on how authentic and settled the finished vehicle looks.
A restoration-minded owner should verify the wheel diameter, inspect the wheels for condition, and avoid assuming that whatever is currently mounted is the right setup. If exact historical accuracy is especially important, period photos, marque resources, and original vehicle literature can help confirm the appearance target before final tire selection.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2000 Mercedes-Benz Trucks ML320?
Yes. Modifications can affect tire fitment on a 2000 Mercedes-Benz Trucks ML320 even when the original size is 255/65R16. Changes to wheel diameter, wheel width, suspension height, or alignment can alter how a replacement tire sits and clears under the vehicle.
That is why the actual SUV should be checked before replacing tires, especially if it has aftermarket wheels or a suspension change from a previous owner. Clearance at full steering lock, overall wheel condition, and the relationship between the tire and bodywork all deserve attention before committing to a new set.
What should I inspect before driving a 2000 Mercedes-Benz Trucks ML320 on new tires?
Before putting a 2000 Mercedes-Benz Trucks ML320 back on the road with new tires, inspect the wheels, valve stems, suspension, steering components, and alignment condition. Tire pressure should also be set correctly, and the vehicle should be checked for any signs of rubbing or unusual tire wear patterns.
An older SUV can hide age-related issues that new tires alone will not solve. Cracked bushings, loose front-end parts, worn shocks, or poor alignment can shorten tire life and affect road manners, so it makes sense to view a tire change as part of a broader road-readiness inspection.
How often should tires on a 2000 Mercedes-Benz Trucks ML320 be inspected?
Tires on a 2000 Mercedes-Benz Trucks ML320 should be inspected regularly, not just when tread appears worn. On a vehicle of this age, condition checks matter because time, storage, and light use can affect a tire even if mileage is relatively low.
Look for sidewall cracking, bulges, cuts, uneven wear, and signs of gradual air loss, and inspect them before longer drives as well as during routine maintenance. A low-use collector-era SUV also benefits from proper storage away from prolonged heat, sunlight, and ozone-producing equipment that can accelerate tire aging.
