2002 Mercedes-Benz Trucks Tire Fitment Guide

2002 Mercedes-Benz Trucks used four tire sizes across four model lines: 265/60R18 for the G500, 255/60R17 for the ML320, 275/55R17 for the ML320 and ML500, and 285/50R18 for the ML55 AMG. The range is split between 17-inch and 18-inch rim diameters, so these fitments are not interchangeable across the entire lineup just because the vehicles share the same year and make.

The practical takeaway is that year and make alone are not enough here. Confirm whether you have a G500, ML320, ML500, or ML55 AMG first, and then verify whether your truck is on 17-inch or 18-inch wheels before you compare tire choices. That matters especially on the ML320, since it appears with two different sizes.

On a 2002 Mercedes-Benz Trucks tire, 265/60R18 is a metric radial size. The 265 is the nominal section width in millimeters, 60 is the aspect ratio, the R identifies radial construction, and 18 is the wheel diameter in inches. Within this model range, that size belongs to the G500 rather than carrying across the full Mercedes-Benz Trucks lineup for 2002.

That code matters because it defines both the tire’s proportions and the wheel it mounts on. If you are working with a G500, 265/60R18 keeps you focused on the correct 18-inch fitment from the start. It also helps you avoid comparing it directly with the 17-inch ML sizes, which may look close on paper but are built for a different wheel diameter.

No, 2002 Mercedes-Benz Trucks models do not all use the same tire size. The G500 uses 265/60R18, the ML320 uses either 255/60R17 or 275/55R17, the ML500 uses 275/55R17, and the ML55 AMG uses 285/50R18. That means size choice changes with the model, and in one case it can also change within the same model family.

For a buyer, that means the model name is every bit as important as the year and make. A G500 owner should be looking at 18-inch fitments, while ML320 and ML500 owners generally start with 17-inch options, and the ML55 AMG has its own 18-inch AMG-specific size. Matching the exact model first will narrow the search much faster.

2002 Mercedes-Benz Trucks vehicles in this size range use metric radial tire sizes, but the exact brand selection depends on the specific size and model. A G500 owner shopping 265/60R18 may see a different mix than an ML320 owner shopping 255/60R17, and an ML55 AMG owner in 285/50R18 should expect that same size-specific pattern.

The best way to narrow the brand choice is to identify the model, confirm the exact size on the truck, and then compare the available tires within that size rather than across the whole year-and-make range. That keeps the choice centered on proper fitment first, then lets you sort by tread character, sidewall appearance, and how the truck will actually be driven.

For a 2002 Mercedes-Benz Trucks ML320, the choice between 255/60R17 and 275/55R17 is a fitment question, not a construction question, because both are radial 17-inch sizes. The 255/60R17 is tied specifically to the ML320, while the 275/55R17 is shared between the ML320 and ML500. Neither should be treated as a universal substitute without confirming the wheel and the truck’s current setup.

Start by checking the tire sidewall already on the vehicle and confirming the wheel diameter. If your ML320 is already set up for 255/60R17, stay with that size unless you have a clear reason to match the alternate factory fitment path. If it is equipped with 275/55R17 wheels and tires, continue with that size so the replacement remains consistent with the wheel package in use.

The right tire for a 2002 Mercedes-Benz Trucks starts with identifying the exact model and then matching its proper size: G500 in 265/60R18, ML320 in 255/60R17 or 275/55R17, ML500 in 275/55R17, and ML55 AMG in 285/50R18. All of these are radial sizes, so the decision is less about bias-ply versus radial and more about model-specific fitment, wheel diameter, and the kind of road use the truck sees.

Once size is settled, compare tires within that exact fitment rather than trying to cross over between models. A collector-used G500, a regularly driven ML320, and an ML55 AMG kept for occasional fair-weather use can all have different priorities, but the first non-negotiable is still the correct size and wheel match. That prevents costly mistakes before you even get to tread design.

2002 Mercedes-Benz Trucks use modern metric radial sizes, and these applications are associated with the kind of wheel-and-tire packages buyers normally expect to run without the older tube-type conventions seen on earlier collector vehicles. The more important issue on this year-and-make range is matching the correct tire size to the correct wheel diameter and confirming the wheel’s condition before mounting.

When replacing tires, inspect the wheels carefully for corrosion, bead-seat damage, or prior repairs, especially on older SUVs that may have seen years of service. If you are working with aftermarket wheels or a wheel of uncertain history, confirm the tire’s sidewall marking and the installer’s recommendations before final assembly. That step matters more here than applying early-vehicle tube rules to a 2002 Mercedes-Benz Trucks fitment.

Original 2002 Mercedes-Benz Trucks wheels can only be shared across sizes when the wheel diameter matches the tire size in question. The 255/60R17 and 275/55R17 both mount on 17-inch wheels, while the 265/60R18 and 285/50R18 both require 18-inch wheels. That means you cannot mount a 17-inch tire on an 18-inch wheel, or the reverse, even if the vehicles come from the same year and make.

Within the same diameter, buyers should still confirm the actual wheel width and vehicle setup before making any change from one size to another. That is especially relevant for the ML320, which appears with two different 17-inch fitments. Staying within the correct diameter is only the first step; the wheel itself and the truck’s existing configuration still need to be checked before ordering.

A 2002 Mercedes-Benz Trucks should be stored in a cool, dry area away from direct sunlight, electric motors, battery chargers, and other ozone sources that can accelerate sidewall aging. Keep the tires properly inflated during storage, and if the vehicle sits for long stretches, move it periodically so the same section of tread does not carry the load month after month.

Long stationary periods are hard on any collector or low-use SUV, even with radial tires. If the truck will remain parked for a season, many owners use tire cradles or place the vehicle on stands to reduce prolonged loading. Clean storage conditions and a little periodic movement go a long way toward preserving both ride quality and sidewall appearance.

Tires on a 2002 Mercedes-Benz Trucks should be judged more by age and condition than by mileage alone, especially when the truck is driven infrequently. A good rule is to begin closer inspection once tires reach the five- to seven-year range and to treat ten years as a point where replacement deserves serious consideration, even if tread depth still looks adequate.

The sidewall date code is the first thing to check, followed by cracking, hardening, irregular wear, and how well the tire holds pressure over time. Luxury SUVs and performance-oriented variants can feel stable enough to mask aging rubber, so visual condition and age matter just as much as ride feel. Older tires may still look usable while no longer being ideal for road service.

Tires on a 2002 Mercedes-Benz Trucks should be inspected before every drive and especially before any longer highway outing. Look for sidewall cracking, cuts, bulges, punctures, uneven wear, and pressure loss, and pay close attention to any tire that has spent long periods parked under load. A brief walkaround catches many problems before they become roadside issues.

A more thorough inspection at regular service intervals is also worthwhile, including tread-depth checks and a close look at the inner sidewall where damage can be easier to miss. If the truck has been sitting, drive the first miles gently and watch for vibration, pull, or other signs that a tire has aged poorly. Collector-minded ownership rewards routine tire attention.

A 2002 Mercedes-Benz Trucks ML320 was fitted with modern radial tire sizing rather than older bias-ply or alphanumeric formats, and the ML320 appears with either 255/60R17 or 275/55R17 depending on the setup. That reflects the fact that by 2002, Mercedes-Benz SUVs were firmly in the modern radial era, with fitments tied closely to wheel package and model configuration.

For an accurate restoration or preservation-oriented refresh, the best course is to confirm the original size from the truck’s factory tire placard, owner’s literature, or a marque specialist familiar with M-Class equipment variations. That is especially helpful on the ML320, since more than one factory size path exists. Getting the exact size right matters more here than chasing a period brand name.

Correct tire fitment does matter when showing a 2002 Mercedes-Benz Trucks, even though this is a modern-era collector vehicle rather than a prewar or muscle-car application. Judges and knowledgeable enthusiasts will notice whether the truck is wearing the proper size for the model, whether the sidewall profile looks appropriate, and whether an AMG model or G-Class appears to sit as it should.

The biggest authenticity errors on this year-and-make range usually come from using the wrong diameter or substituting a size from another model because it seems close enough. A G500, ML320, ML500, and ML55 AMG each have their own fitment logic. If show accuracy matters, confirm the exact original size through factory references and marque circles before making a change.

Model-specific tire sizing is important on a 2002 Mercedes-Benz Trucks restoration because the range is not built around one universal fitment. The G500 uses 265/60R18, the ML500 uses 275/55R17, the ML55 AMG uses 285/50R18, and the ML320 can use either 255/60R17 or 275/55R17. Those differences affect wheel diameter, sidewall shape, and the visual stance that helps each model look correct.

That means a restoration-minded owner should treat tire selection as part of the vehicle’s identity, not just a maintenance item. The right size supports the proper appearance and keeps the truck aligned with how that model was equipped in period. If there is any doubt about what belongs on your specific example, factory references and marque communities are the safest next stop.

A properly sized, correctly inflated, and healthy radial tire is entirely appropriate for highway use on a 2002 Mercedes-Benz Trucks, provided it is in good condition and suited to the vehicle’s wheel size. These are modern radial formats rather than early bias-ply collector sizes, so normal highway use is well within the kind of service these applications were designed around when new.

Real-world safety depends just as much on age, condition, suspension health, brakes, and alignment as it does on the size molded into the sidewall. That is especially true for heavier luxury SUVs and performance variants such as the ML55 AMG, where an old tire can undermine an otherwise capable chassis. Before longer drives, focus on fresh rubber, correct pressure, and a sound overall mechanical baseline.

Inflation pressure for 2002 Mercedes-Benz Trucks should be matched to the exact model, tire size, load condition, and the manufacturer guidance for the tire you are using. Because this year-and-make range includes multiple sizes across different models, pressure should not be copied from one fitment to another simply because the trucks are all Mercedes-Benz SUVs from 2002.

Use the factory placard or owner’s manual as your starting point for the vehicle’s intended setup, then confirm that choice against the tire maker’s own recommendations and maximum sidewall figures. A G500 on 265/60R18, an ML320 on either 17-inch size, and an ML55 AMG on 285/50R18 can each call for different pressures in practice. Matching pressure to the exact application is part of safe setup.

Before a longer drive in a 2002 Mercedes-Benz Trucks, inspect each tire for cracking, cuts, bulges, punctures, uneven wear, and proper inflation, and make sure the spare is usable as well. Confirm that the size on the vehicle matches the model’s intended fitment, since this year-and-make range includes multiple model-specific tire sizes across both 17-inch and 18-inch wheels.

Tires are only one part of the pre-trip picture on a twenty-plus-year-old luxury SUV. Check brakes, fluids, steering response, and suspension condition, and listen for vibration or wheel-bearing noise during the first few miles. A careful once-over before departure is especially worthwhile if the truck has spent much of its time in storage or only sees occasional seasonal use.
