In 2005 Mercedes-Benz Trucks combined luxury SUV engineering with serious road presence, spanning the rugged, upright G-Class and the more modern, comfort-focused ML range. Buyers shopping this year often arrive knowing they have a Mercedes-Benz truck, but tire choice changes noticeably once you separate a G500 from a G55 AMG or an ML350 from an ML500. Four radial sizes were used across four models, and they are not shared universally across the lineup, so the real starting point is identifying the exact model and its wheel diameter before narrowing down the right tire. Once that is confirmed, choosing the correct size becomes much more straightforward.
Which Tire Size Is Right for Your 2005 Mercedes-Benz Trucks
Four tire sizes were used across 2005 Mercedes-Benz Trucks models, and they vary by model rather than carrying across the entire lineup. Because these sizes span both 17-inch and 18-inch wheel fitments, the first step is confirming the correct model and rim diameter before comparing tire options. Understanding that distinction before choosing a product saves time and helps match the tire to the right vehicle.
Year(s): 2005|Fit(s): G500|Construction: Radial|Rim: 18-in rim
A 265/60R18 uses a 265-millimeter section width, a 60-series aspect ratio, radial construction, and fits an 18-inch wheel. This is a model-specific size for the 2005 Mercedes-Benz Trucks G500 rather than a universal fitment across the full range. It is the right starting point for a G500 owner who wants to stay with the factory-style dimensional approach used on that model.
Year(s): 2005|Fit(s): G55 AMG|Construction: Radial|Rim: 18-in rim
A 285/55R18 carries a 285-millimeter section width, a 55-series aspect ratio, radial construction, and mounts on an 18-inch wheel. This size is specific to the 2005 Mercedes-Benz Trucks G55 AMG, so it should be matched to that AMG application rather than treated as interchangeable with the rest of the lineup. Buyers with a G55 AMG should confirm the vehicle is still on its correct 18-inch wheels before moving ahead.
Year(s): 2005|Fit(s): ML350|Construction: Radial|Rim: 17-in rim
A 255/60R17 means a 255-millimeter section width, a 60-series aspect ratio, radial construction, and a 17-inch wheel diameter. This size is used on the 2005 Mercedes-Benz Trucks ML350 and is not shared across every model in the year-and-make range. It suits ML350 owners who are confirming the narrower of that model's two fitment paths before selecting a tire.
Year(s): 2005|Fit(s): ML350, ML500|Construction: Radial|Rim: 17-in rim
A 275/55R17 uses a 275-millimeter section width, a 55-series aspect ratio, radial construction, and fits a 17-inch wheel. This size is shared by the 2005 Mercedes-Benz Trucks ML350 and ML500, making it one of the crossover fitments within the lineup rather than a whole-range size. It is the size to focus on when comparing those two ML models or confirming whether an ML350 uses the wider 17-inch application.
Four Mercedes-Benz truck models are covered for 2005. Tire size varies by model, and in the case of the ML350, more than one size enters the picture, so identifying the exact model matters before choosing a tire.

2005 Mercedes-Benz Trucks G500
The 2005 Mercedes-Benz Trucks G500 carried the classic G-Class formula of a boxy body, upscale interior appointments, and genuine off-road heritage. Its tire fitment mounts on an 18-inch wheel, which separates it from the 17-inch ML models and gives G500 owners a clear model-specific starting point.
The 2005 Mercedes-Benz Trucks G55 AMG took the rugged G-Class platform and added AMG power and a more aggressive personality. Its tires mount on 18-inch wheels as well, but the size is distinct from the G500, so AMG owners should verify they are matching the tire to the performance-oriented G55 application.
The 2005 Mercedes-Benz Trucks ML350 was the more mainstream luxury SUV in the range, blending everyday comfort with Mercedes-Benz utility. It uses 17-inch wheel fitments, and it is the only model here that appears with two different tire sizes, making model-level confirmation especially important before ordering.
The 2005 Mercedes-Benz Trucks ML500 sat higher in the ML lineup, offering a more premium and powerful take on the same general platform. Its tires mount on 17-inch wheels and use the wider of the two ML-family sizes, which it shares with certain ML350 applications.
These FAQs focus on the model-by-model size split within 2005 Mercedes-Benz Trucks, how the 17-inch and 18-inch fitments differ, and what to verify before putting collector or daily-driven G-Class and ML vehicles back on the road.
Size Basics & Fitment
What tire sizes fit 2005 Mercedes-Benz Trucks vehicles?
2005 Mercedes-Benz Trucks models use four sizes: 265/60R18 for the G500, 285/55R18 for the G55 AMG, 255/60R17 for the ML350, and 275/55R17 for the ML350 and ML500. That means the lineup does not share one universal size. The G-Class models use 18-inch wheel diameters in these applications, while the ML models here use 17-inch wheel diameters.
The practical takeaway is that year and make alone are not enough for this Mercedes-Benz group. You need to confirm whether you have a G500, G55 AMG, ML350, or ML500, and ML350 owners should also verify which of the two 17-inch sizes belongs on the vehicle. Checking the tire sidewall currently on the vehicle and confirming the wheel diameter before ordering is the safest starting point.
What does 265/60R18 mean on a 2005 Mercedes-Benz Trucks tire?
On a 2005 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, R means radial construction, and 18 is the wheel diameter in inches. Within this year-and-make range, that size belongs to the G500.
That code matters because it tells you both the tire's general proportions and the wheel diameter it must fit. A tire with the wrong final number will not mount on the wheel, even if the vehicle is from the same year and make. G500 owners should use 265/60R18 as the baseline size reference, then confirm the exact wheel and current fitment before choosing a specific replacement.
Do all 2005 Mercedes-Benz Trucks models use the same tire size?
No, 2005 Mercedes-Benz Trucks models do not all use the same tire size. The G500 uses 265/60R18, the G55 AMG uses 285/55R18, the ML350 appears with either 255/60R17 or 275/55R17, and the ML500 uses 275/55R17. Only the ML350 and ML500 overlap on one size, and the rest are model-specific.
That difference reflects the fact that these vehicles serve different purposes within the Mercedes-Benz lineup, from the traditional G-Class to the more crossover-like ML range. If you are unsure which size belongs on your truck, start by identifying the model and confirming the wheel diameter already on the vehicle. That step prevents mixing an 18-inch G-Class fitment with a 17-inch ML fitment that will not interchange.
Buying the Right Tire
What brands make tires for 2005 Mercedes-Benz Trucks vehicles?
Tire brand coverage cannot be generalized across the full 2005 Mercedes-Benz Trucks lineup without first narrowing the vehicle to its exact size. The important point at the year-and-make level is that each size stands on its own fitment path: G500 on 265/60R18, G55 AMG on 285/55R18, ML350 on 255/60R17 or 275/55R17, and ML500 on 275/55R17.
Once you know the size, brand comparison becomes much more meaningful because construction, sidewall design, and intended use can be weighed within the correct fitment category. For buyers who want to stay close to factory dimensions, the size should be chosen first and the brand second. That approach keeps the search focused on tires that actually belong on the correct Mercedes-Benz application.
What sidewall styles are available for 2005 Mercedes-Benz Trucks tires?
Sidewall style matters on 2005 Mercedes-Benz Trucks because these vehicles sit at the intersection of luxury and utility, and sidewall appearance can change the truck's overall character. G-Class owners often want a purposeful look that still suits the upright body and premium trim, while ML owners may prefer a more understated appearance that fits a modern luxury SUV profile.
The best approach is to choose the correct size first, then compare sidewall styling within that size so the appearance stays consistent with the truck's personality and intended use. A G55 AMG may call for a different visual tone than a standard G500, and an ML350 may not be styled exactly like an ML500. Matching the sidewall to the vehicle's role is often just as important as matching the dimensions.
How do I choose the right tire for my 2005 Mercedes-Benz Trucks model?
Choosing the right tire for a 2005 Mercedes-Benz Trucks model starts with identifying the exact model and its wheel diameter. The G500 uses 265/60R18, the G55 AMG uses 285/55R18, the ML350 uses either 255/60R17 or 275/55R17, and the ML500 uses 275/55R17. All four sizes are radial, so the main question is correct application rather than a bias-ply versus radial decision.
After the size is confirmed, think about how the truck is used. A lightly driven collector G-Class, a regularly exercised ML, and a more performance-minded G55 AMG can all call for different priorities in ride feel, appearance, and speed capability even when the dimensions are fixed. Matching the tire to the model first, then to your driving habits, leads to a much better result than choosing by appearance alone.
Fitting & Setup
Do 2005 Mercedes-Benz Trucks tires require inner tubes?
2005 Mercedes-Benz Trucks fitments in this group are all modern radial sizes, which generally point buyers toward tubeless-style applications rather than early tube-type collector formats. The sizes themselves are 265/60R18, 285/55R18, 255/60R17, and 275/55R17, all of which belong to a modern SUV era rather than a vintage tube-type era.
Even so, the wheel itself still matters. If a wheel has been changed, repaired, or adapted from its original configuration, tube requirements should be confirmed against the exact wheel and the tire's own sidewall marking before installation. That is especially important on older used vehicles where wheel history may not be obvious from the outside.
Can the original 2005 Mercedes-Benz Trucks wheels be used with all tire sizes?
No, the original 2005 Mercedes-Benz Trucks wheels cannot be treated as universal across all four sizes. The G500 and G55 AMG sizes fit 18-inch wheels, while the ML350 and ML500 sizes here fit 17-inch wheels. A tire's final diameter number must match the wheel diameter exactly.
That means an 18-inch G-Class tire cannot simply be mounted on a 17-inch ML wheel, and a 17-inch ML tire cannot be stretched onto an 18-inch wheel. ML350 owners should be especially careful because that model appears with two sizes that share the same wheel diameter but differ in width and profile. Confirm the actual wheel and current fitment before making any change.
Maintenance, Storage & Longevity
How should I store a 2005 Mercedes-Benz Trucks when the tires are fitted?
A 2005 Mercedes-Benz Trucks vehicle should be stored away from direct sunlight, standing moisture, and ozone-producing sources such as electric motors, battery chargers, and some shop equipment. Clean, dry concrete or a barrier under the tires is better than letting the tires sit in damp conditions for long periods. Keeping the tires properly inflated during storage also helps them hold their shape.
Moving the vehicle occasionally is helpful because it changes the loaded section of the tire and reduces the chance of temporary flat spotting. If the truck will sit for an extended season, many owners use tire cradles or support the vehicle in a way that reduces static load while staying appropriate to the suspension design. That is especially worthwhile for collector G-Class trucks and low-use ML models.
How long do tires on a 2005 Mercedes-Benz Trucks typically last?
Tires on a 2005 Mercedes-Benz Trucks vehicle should be judged by age and condition at least as much as by tread depth. A common collector-vehicle rule is to begin evaluating closely around five to seven years of age and to give serious replacement consideration as a tire approaches about ten years, even if the tread still looks usable. The DOT date code on the sidewall is the key age reference.
That matters because many G-Class and ML vehicles are driven far less than modern daily transportation, so mileage can look low while rubber aging continues. Heat cycles, storage conditions, inflation history, and exposure to sunlight all affect tire life. If the truck is newly purchased, checking the age of all five tires, including the spare, is one of the smartest first inspections you can make.
How often should tires on a 2005 Mercedes-Benz Trucks be inspected?
Tires on a 2005 Mercedes-Benz Trucks vehicle should be inspected before every drive and more carefully before any longer road trip. Look for sidewall cracking, cuts, punctures, irregular tread wear, bulges, and any sign that the tire has been run low. Pressure should also be checked regularly, not just by appearance.
That routine is especially important on vehicles that alternate between long storage periods and occasional highway use. A truck can seem fine around town and still reveal age-related issues only after heat builds at speed. If the steering suddenly feels different, the vehicle pulls, or vibration increases, stop and inspect the tires before continuing rather than assuming it is only an alignment or suspension quirk.
Safety & Road Use
Are 2005 Mercedes-Benz Trucks tires safe for highway driving?
A correctly sized, properly maintained tire in the right condition can be suitable for highway driving on a 2005 Mercedes-Benz Trucks vehicle. These are all modern radial SUV sizes, which align with the highway use expected of the G500, G55 AMG, ML350, and ML500. Tire condition, age, inflation, and proper matching to the vehicle matter more than the year alone.
Highway safety should be viewed as a whole-vehicle question, not just a tire question. A powerful G55 AMG or a heavy luxury SUV places real demands on brakes, suspension, alignment, and load control, so tires should be only one part of the pre-drive evaluation. If the tires are old, unevenly worn, or of uncertain history, replacing them before regular highway use is the prudent move.
What inflation pressure should I use for 2005 Mercedes-Benz Trucks tires?
Inflation pressure for 2005 Mercedes-Benz Trucks tires should follow the vehicle's factory recommendation for the exact model and size, typically found on the driver's door placard or in the owner's literature. That matters here because the lineup uses four different sizes across different models, and pressure should never be copied casually from one size to another just because the vehicles share a make.
Once the correct baseline pressure is confirmed, recheck it with the tires cold and adjust for the vehicle's normal load and use. A G500, G55 AMG, ML350, and ML500 can have different weight distribution and operating expectations, so correct pressure is part of preserving handling, tread wear, and ride quality. Pressure checks should be a routine habit rather than a seasonal afterthought.
What should I check before taking a 2005 Mercedes-Benz Trucks on a longer drive?
Before taking a 2005 Mercedes-Benz Trucks vehicle on a longer drive, inspect every tire for cracking, cuts, bulges, embedded debris, and uneven wear, then verify cold inflation pressure. Check that the spare is present and usable, and make sure the tire size on the vehicle matches the correct model application. A quick visual inspection is not enough if the truck has been sitting for a long time.
Longer trips are where age, storage history, and neglected maintenance tend to surface. Beyond the tires, older premium SUVs and specialty models benefit from a broader check of brakes, fluids, suspension, and steering before sustained highway use. Spending a few minutes on those basics helps a 2005 G-Class or ML feel composed and dependable instead of turning a simple trip into a roadside problem.
