The 2009 Mercedes-Benz Trucks G55 AMG blends hand-built AMG performance with the upright, military-rooted shape that makes the G-Class so instantly recognizable. By this point, the formula was firmly established: serious road presence, substantial weight, and a tire package that had to support both appearance and capability. This exact model uses a 275/55R19 radial tire on a 19-inch rim, giving the page a very focused fitment story. The real choice is less about multiple factory sizes and more about selecting the right radial tire within that size while keeping wheel compatibility, overall stance, and intended road use in mind.
Which Tire Size Is Right for The 2009 Mercedes-Benz Trucks G55 AMG
The 2009 Mercedes-Benz Trucks G55 AMG uses one primary tire size: 275/55R19, and it is a radial fitment on a 19-inch rim. The Base model uses that same size, so the main decision is not sorting through multiple factory sizes but choosing the right tire within 275/55R19 and confirming that the wheel setup on the vehicle still matches stock dimensions if any modifications have been made.
In 275/55R19, the 275 identifies the nominal section width in millimeters, the 55 is the aspect ratio, the R denotes radial construction, and the 19 indicates the wheel diameter in inches. For the 2009 Mercedes-Benz Trucks G55 AMG, this is the primary fitment format and it suits a modern high-profile SUV tire package rather than a vintage bias-ply setup. With a single size used across the covered model, the buyer's attention shifts to tire design, load suitability, and wheel compatibility. It is also important to confirm that any aftermarket wheels or suspension changes have not altered the vehicle's actual fitment requirements.
Sub-model fitment is straightforward for the 2009 Mercedes-Benz Trucks G55 AMG. The covered sub-model uses the same primary tire size, so selection comes down more to choosing the right tire within that fitment than sorting through different factory size combinations.

Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
These FAQs focus on the exact tire size used on the 2009 Mercedes-Benz Trucks G55 AMG, along with rim fitment, tire selection, appearance considerations, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2009 Mercedes-Benz Trucks G55 AMG?
The 2009 Mercedes-Benz Trucks G55 AMG uses a 275/55R19 radial tire. That size is the primary fitment for this model and gives the buyer a clear starting point when replacing worn tires or evaluating the current setup on the vehicle.
A single factory size does not always mean every truck still wears the original wheel and suspension combination. It is worth checking the installed wheel diameter, wheel width, and clearance if the G55 AMG has aftermarket wheels, a changed ride height, or other modifications that could affect fitment.
What size rim does a 2009 Mercedes-Benz Trucks G55 AMG use?
The 2009 Mercedes-Benz Trucks G55 AMG uses a 19-inch rim with its 275/55R19 tire size. That rim diameter is built into the tire code itself, with the final number showing the wheel diameter the tire is designed to mount on.
Rim diameter is the first fitment point to confirm, but it should not be the only one. Wheel width and the vehicle's actual setup still matter, especially on a performance SUV where aftermarket wheels are common and can change how a tire sits or clears suspension and body components.
Does the 2009 Mercedes-Benz Trucks G55 AMG Base use the same tire size?
Yes. The 2009 Mercedes-Benz Trucks G55 AMG Base uses the same 275/55R19 radial tire size. That makes fitment straightforward across the covered sub-model and avoids the confusion that can come with trim-specific tire packages.
Even with shared fitment, it is still smart to inspect the truck before choosing replacement tires. A previous owner may have changed the wheels or suspension, and that can affect the practical tire choice even when the original size for the Base model remains 275/55R19.
Choosing the Right Tire
What should I consider when choosing a 275/55R19 tire for a 2009 Mercedes-Benz Trucks G55 AMG?
Start with the correct size and construction: 275/55R19 radial on a 19-inch wheel. From there, the important considerations are whether the tire suits the vehicle's actual wheel dimensions, supports the way the truck is driven, and matches the overall look the owner wants to preserve.
The G55 AMG's tall, boxy shape and substantial weight make setup verification especially important. Compare the tire against the installed wheels, inspect clearance at steering lock, and make sure any replacement choice works with the current suspension height and the way the vehicle is used on the road.
How do I choose between the available 275/55R19 tires for a 2009 Mercedes-Benz Trucks G55 AMG?
The right choice comes from balancing fitment, intended use, and presentation rather than looking for a one-answer tire. Since the 2009 Mercedes-Benz Trucks G55 AMG uses a single primary size, the comparison centers on which 275/55R19 option best matches the vehicle's wheel setup and driving expectations.
One truck may be used mostly for occasional street driving, while another may spend more time on longer highway runs or show-oriented use. A careful buyer should compare tire construction details, confirm the mounted wheel dimensions, and look closely at how the chosen tire will sit within the vehicle's existing setup.
What rim-width specifications should I compare when choosing 2009 Mercedes-Benz Trucks G55 AMG tires?
Rim width should be compared alongside the 275/55R19 tire size because diameter alone does not tell the whole fitment story. A tire may share the correct 19-inch wheel diameter yet behave differently depending on the wheel width actually installed on the truck.
That matters on a G55 AMG because many examples have seen wheel changes over time. Measuring the current wheels and matching the replacement tire to those dimensions helps avoid a setup that looks pinched, stretched, or too close to suspension and body clearances during normal driving and steering movement.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Mercedes-Benz Trucks G55 AMG?
A period-style choice for a 2009 Mercedes-Benz Trucks G55 AMG starts with retaining the correct 275/55R19 radial size and the proper 19-inch wheel relationship. Because this is a modern AMG-era fitment, preserving the original overall stance and proportions usually matters more than pursuing an older tire construction style.
Appearance-focused buyers should pay attention to how the tire fills the wheel opening and how closely it suits the truck's existing visual setup. If originality matters at a detailed level, compare the replacement tire against period photos, original sales literature, or marque-specific references before making the final choice.
Does correct tire fitment matter for a 2009 Mercedes-Benz Trucks G55 AMG restoration?
Yes, correct tire fitment matters because the 2009 Mercedes-Benz Trucks G55 AMG has a very defined stance and a tire size that contributes to both its visual balance and road manners. Staying with the proper 275/55R19 radial fitment keeps the restoration grounded in the model's intended wheel-and-tire relationship.
A truck can look noticeably off when tire size, sidewall height, or wheel diameter have been changed without a clear plan. During a restoration, confirm the wheels currently on the vehicle, inspect for prior modifications, and make sure the tire choice supports the look and use the finished G55 AMG is meant to have.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Mercedes-Benz Trucks G55 AMG?
Yes. Modifications can change how a 275/55R19 tire works on a 2009 Mercedes-Benz Trucks G55 AMG even when the nominal size remains the same. Aftermarket wheels, altered offsets, suspension changes, or ride-height adjustments can all influence clearance, steering behavior, and the way the tire sits on the vehicle.
A careful inspection should include wheel diameter, wheel width, and clearance at full steering lock. Looking at inner fender space and suspension proximity is also worthwhile, especially on a modified truck, because a size that is correct in theory can still create practical fitment issues on an altered setup.
What should I inspect before driving a 2009 Mercedes-Benz Trucks G55 AMG on new tires?
Inspect the wheels, valve stems, tire pressures, and visible clearance around the suspension and body before regular road use. It is also worth checking that the tires are seated properly, that there is no rubbing at steering lock, and that the truck tracks normally once the new set is installed.
Collector-oriented and performance SUVs often spend periods parked, so a broader inspection is smart as well. Look for signs of uneven wear, prior alignment issues, or aging components that could affect the new tires, and recheck pressure and wheel fastener torque after the first period of driving.
How often should tires on a 2009 Mercedes-Benz Trucks G55 AMG be inspected?
Tires on a 2009 Mercedes-Benz Trucks G55 AMG should be inspected regularly, not just when tread looks low. A quick visual check before driving and a more careful inspection at routine service intervals helps catch cracking, cuts, bulges, uneven wear, or slow air loss before they become larger problems.
That schedule matters even more when the truck is driven infrequently. Low-use vehicles can age their tires without accumulating many miles, so pressure, sidewall condition, and general tire age deserve attention along with tread condition, especially before a longer highway trip or extended seasonal use.
