The 2005 Mercedes-Benz Trucks G500 sits at an interesting point in G-Class history, combining the long-running military-rooted design with a more luxurious road-going personality. Buyers are usually balancing utility, collector appeal, and the unmistakable squared-off look that defines this truck. For this model year, the primary fitment is a 265/60R18 radial tire on an 18-inch rim, so the main decision is less about multiple factory sizes and more about choosing the right tire within that fitment. That means paying attention to road-use goals, overall stance, and any wheel or suspension changes that may affect how an 18-inch radial setup works on the truck today.
Which Tire Size Is Right for The 2005 Mercedes-Benz Trucks G500
The 2005 Mercedes-Benz Trucks G500 uses one primary tire size: 265/60R18. It is a radial fitment on an 18-inch rim, and the covered Base sub-model uses that same size, so the real choice is selecting the right tire style and specification within that fitment while confirming the truck still has the intended wheel setup.
A 265/60R18 tire uses a modern metric sizing format: 265 indicates nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 18 is the rim diameter in inches. On the 2005 Mercedes-Benz Trucks G500, this radial format suits the truck's later-era combination of everyday road use and substantial utility presence. Because this is a modern radial size, buyers typically focus on choosing the right tire character within the size rather than decoding an older bias-ply designation. It is still worth confirming wheel dimensions and clearance if the truck has aftermarket wheels, suspension changes, or a stance different from stock.
Fitment is straightforward for the covered 2005 Mercedes-Benz Trucks G500 sub-models. The Base model uses the same primary tire size, so tire selection centers on choosing the right 265/60R18 radial and verifying that the truck's current wheels still match the intended setup.

Frequently Asked Questions
These FAQs focus on 2005 Mercedes-Benz Trucks G500 tire size, 18-inch rim fitment, choosing the right 265/60R18 radial, and the checks that matter before putting a collector-used or modified G500 back on the road.
Tire Size & Fitment
What tire size fits a 2005 Mercedes-Benz Trucks G500?
The 2005 Mercedes-Benz Trucks G500 uses a 265/60R18 tire. This is a modern metric radial size, and it is the primary fitment for the covered vehicle configuration. The Base sub-model uses that same 265/60R18 radial size, which makes the basic size question more straightforward than on vehicles with multiple factory tire options.
The practical next step is confirming that the truck still has 18-inch wheels in the intended setup. A G500 with aftermarket wheels, altered suspension height, or body modifications may need closer clearance checks even when the tire size itself is correct. Tire selection should start with 265/60R18, then move to wheel compatibility, intended use, and the condition of the current chassis and steering components.
What size rim does a 2005 Mercedes-Benz Trucks G500 use?
The primary tire fitment for the 2005 Mercedes-Benz Trucks G500 is built around an 18-inch rim. That rim diameter matches the 265/60R18 tire size, where the final number in the size code indicates the wheel diameter in inches. For this vehicle, confirming 18-inch wheels is a key part of selecting the correct replacement tire.
Wheel diameter is only one part of the fitment picture, so it helps to check wheel width and overall wheel setup before mounting new tires. A truck that has changed hands over the years may no longer have its original-style wheel package. Verifying the actual wheel dimensions on the vehicle helps avoid selecting the right tire size for the wrong wheel configuration.
Does the 2005 Mercedes-Benz Trucks G500 Base use the same tire size?
Yes. The 2005 Mercedes-Benz Trucks G500 Base uses the same 265/60R18 radial tire size. That means the covered G500 fitment does not branch into separate primary sizes by sub-model here, which simplifies replacement planning and keeps the focus on choosing the right tire within one established size.
Even with shared fitment, it is still smart to inspect the truck itself before ordering or mounting tires. Older G-Class trucks are often personalized with different wheels, ride heights, or off-road accessories, and those changes can influence clearance. Matching the 265/60R18 size is the starting point, but the actual wheel and suspension setup should still be checked on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 265/60R18 tire for a 2005 Mercedes-Benz Trucks G500?
Start with the correct size, which is 265/60R18, and make sure the tire is intended for an 18-inch wheel. Since this G500 uses a modern radial fitment, the main considerations are choosing a tire that suits how the truck is driven, confirming wheel compatibility, and keeping the overall look and stance appropriate to the vehicle.
A careful buyer should also think about whether the truck is mostly road driven, stored for long periods, or used in a way that puts extra demand on tires and suspension. It helps to compare wheel dimensions, inspect for rubbing at full steering lock, and make sure the chosen tire matches the current configuration rather than assuming every G500 still wears its original-style wheel setup.
How do I choose between the available 265/60R18 tires for a 2005 Mercedes-Benz Trucks G500?
Choosing between 265/60R18 tires for a 2005 Mercedes-Benz Trucks G500 starts with fitment, then moves to use case and presentation. The correct size and 18-inch wheel match come first. After that, the better choice depends on whether the truck is driven regularly, kept as a collector vehicle, or expected to preserve a more traditional G-Class appearance.
Looking beyond the size code is important because two tires in the same nominal size can still differ in character and how they suit the truck. Compare construction details, confirm the wheel setup on the vehicle, and think about how the G500 will actually be used. That approach is more useful than choosing by appearance alone or assuming every 265/60R18 behaves the same.
What rim-fitment details should I compare when choosing 2005 Mercedes-Benz Trucks G500 tires?
The first rim-fitment detail to verify is diameter, since the 2005 Mercedes-Benz Trucks G500 uses an 18-inch wheel with its 265/60R18 tire size. After that, check the actual wheel width and overall wheel setup on the truck. Those details affect how appropriately a tire seats on the rim and whether the combination remains suitable for the vehicle.
It also helps to inspect wheel condition and confirm that the current wheels are the ones you intend to keep. Replacement or aftermarket wheels can change the fitment picture even when the rim diameter remains 18 inches. Taking measurements from the truck itself reduces the chance of selecting a tire that matches the size code but not the vehicle's actual wheel and clearance situation.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Mercedes-Benz Trucks G500?
A period-style starting point for a 2005 Mercedes-Benz Trucks G500 is the correct primary size, 265/60R18, on the proper 18-inch wheel diameter. Because this is a newer collector-era truck with a modern radial fitment, maintaining the intended size does more for preserving its visual balance than trying to force an older-looking tire format onto it.
Appearance still needs to be weighed against how the truck will be driven and whether it retains its original-style wheel package. A G500 that has been modified can look quite different even with the right nominal tire size. Buyers focused on authenticity should confirm wheel and vehicle presentation against marque-specific references before deciding that any one tire appearance is the right restoration choice.
Does correct tire fitment matter for a 2005 Mercedes-Benz Trucks G500 restoration?
Yes, correct tire fitment matters because the 2005 Mercedes-Benz Trucks G500 has a very defined stance and wheel-to-body relationship. Staying with the proper 265/60R18 radial size helps preserve the truck's proportions and keeps the visual presentation closer to what enthusiasts expect from this era of G-Class road model.
Fitment also affects more than looks. The wrong wheel or tire combination can create rubbing, alter the truck's stance, or make the vehicle appear noticeably off even at a glance. For a restoration-minded owner, correct size, proper 18-inch wheel diameter, and a careful check of the truck's current setup usually matter more than chasing a tire choice based only on style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Mercedes-Benz Trucks G500?
Yes, modifications can affect tire fitment on a 2005 Mercedes-Benz Trucks G500 even when the intended size is still 265/60R18. Changes such as aftermarket wheels, suspension lifts or lowering, body trim differences, and steering or brake alterations can all influence how much space the tire has at full lock and through suspension travel.
That is why the size code alone should not be the only check on a modified truck. Verifying wheel dimensions, observing clearance at the fenders and suspension, and confirming there is no rubbing under real driving movement are sensible steps. A G500 that has been changed from its original setup may need more fitment attention than an unmodified example.
What should I inspect before driving a 2005 Mercedes-Benz Trucks G500 on new tires?
Before driving a 2005 Mercedes-Benz Trucks G500 on new tires, inspect the wheels, lug hardware, tire pressure, and visible clearance around the fenders and suspension. It is also wise to check steering response at low speed and confirm there is no contact at full turn. New tires should never be treated as the only part of the truck worth examining.
A broader pre-drive inspection helps catch problems that new tires will not solve, such as worn steering parts, alignment issues, or aged suspension components. The truck should also be checked for side-to-side consistency, proper inflation retention, and any signs that the wheel setup is not centered correctly. That extra inspection matters on collector-used vehicles that may sit for long periods.
How should 265/60R18 tires on a collector 2005 Mercedes-Benz Trucks G500 be maintained?
Collector-used 265/60R18 tires on a 2005 Mercedes-Benz Trucks G500 should be kept properly inflated, inspected regularly, and protected from long periods of harsh storage conditions. Even a truck that is driven sparingly can develop age-related issues such as cracking, flat spotting, air loss, or sidewall deterioration if it sits too long without attention.
Routine checks should include tread condition, sidewall surfaces, valve stems, and any bulges or cuts that suggest the tire should not remain in service. Storage habits matter too, especially around heat, direct sunlight, and ozone sources. A G500 that sees occasional use benefits from periodic movement and inspection so the tires stay roadworthy rather than merely looking acceptable.
