The 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG takes the already distinctive G-Class formula into far more specialized territory, blending luxury SUV presence with portal-axle stance, serious ground clearance, and a highly visual off-road character. On a vehicle like this, tire fitment is part of both the look and the functional package. The primary fitment is a 325/55R22 radial on a 22-inch rim, giving this exact model one clear modern-size reference point. That makes the real decision less about sorting through multiple factory sizes and more about preserving the intended proportions, confirming wheel compatibility, and making sure any replacement matches the vehicle's substantial stance and road-use needs.
Which Tire Size Is Right for The 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG
The 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG uses one primary tire size: 325/55R22 radial on a 22-inch rim. The Base sub-model uses this same size, so the main choice is not between different factory fitments but between replacement tires that maintain the correct sizing, wheel compatibility, and overall presence expected on this high-clearance AMG platform.
A 325/55R22 size uses a modern metric radial format: 325 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 22 is the rim diameter in inches. On the 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG, that sizing supports the vehicle's large-scale proportions and specialized wheel-and-tire presentation. Because this is a single primary fitment rather than one of several factory sizes, selection centers on staying true to the intended dimensions and confirming the actual wheel setup on the vehicle. That becomes especially important if the truck has seen wheel, suspension, or ride-height changes.
Sub-model fitment is straightforward for this vehicle. The covered G63 4x4 Squared AMG Base uses the same primary tire size, so the key step is confirming the truck still carries the correct 22-inch wheel setup before choosing a replacement tire.

Frequently Asked Questions
Owners researching tires for a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG usually need clear answers on the 325/55R22 size, 22-inch rim fitment, replacement selection, and the checks that matter before road use on a specialized high-clearance SUV.
Tire Size & Fitment
What tire size fits a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG?
The 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG uses a 325/55R22 radial tire. That is the primary fitment for this model and it matches a 22-inch rim, making it the central reference point when replacing worn tires or evaluating the wheel-and-tire package already on the truck.
Using the correct size matters because this vehicle's stance, clearance, and visual proportions are closely tied to its large tire package. A replacement should be checked against the actual wheels on the vehicle, especially if it has aftermarket rims, suspension changes, or other modifications that could affect clearance and fitment.
What size rim does a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG use?
The primary tire fitment for the 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG is built around a 22-inch rim. The 325/55R22 size confirms that wheel diameter, since the final number in the tire size identifies the rim diameter in inches for this modern metric radial format.
Rim diameter should be confirmed before shopping because a tire meant for a 22-inch wheel cannot be mounted on a different diameter rim. It is also worth verifying the actual wheel setup on the vehicle, since custom SUVs are often changed from stock-style configurations after delivery.
Does the 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG Base use the same tire size?
Yes. The 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG Base uses the same 325/55R22 radial tire size as the core model fitment. That keeps sub-model selection simple, since there is not a separate alternate primary tire size to sort through within the covered configuration.
Even with a shared size, it still helps to inspect the actual truck before buying replacements. Wheel changes, suspension alterations, and aggressive offset choices can change how a correctly sized tire behaves at full steering lock or under compression, so the mounted setup deserves a quick verification.
Choosing the Right Tire
What should I consider when choosing a 325/55R22 tire for a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG?
Start with the basics that define the fitment: 325/55R22 size, radial construction, and a 22-inch wheel. On this vehicle, staying with the proper dimensions is important because the tire contributes to both the truck's intended proportions and its practical clearance relationship with the wheels, suspension, and body.
After size is confirmed, compare the actual wheel setup and how the vehicle is used. A mostly road-driven truck, a lightly used collector example, and a customized build may all call for slightly different priorities, but the safest starting point is preserving the established size and checking wheel compatibility carefully.
How do I choose between replacement tires for a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG?
The first filter is fitment accuracy rather than brand comparison. A replacement tire for a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG should match the 325/55R22 size and 22-inch rim requirement, since that is the known primary specification for this model.
From there, selection becomes a matter of matching the tire to the truck's actual setup and intended use. Look closely at wheel dimensions, any modifications already made to the vehicle, and the kind of driving expected, then confirm that the replacement preserves adequate clearance and the visual balance of the original package.
Why is the exact 325/55R22 size important on a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG?
The 325/55R22 size is important because it establishes the basic width, profile, radial construction, and rim diameter used on the 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG. On a highly specialized vehicle with a tall stance and large wheel package, the tire is a major part of the engineered overall setup.
Changing away from that baseline without careful measurement can affect more than appearance. Steering clearance, fender space, and wheel compatibility should all be reviewed before any size change is considered, particularly on a vehicle that may already sit differently because of custom wheels or suspension work.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG?
Yes. Modifications can affect tire fitment on a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG even when the tire size itself remains 325/55R22. Wheel offset changes, aftermarket wheels, suspension alterations, and body modifications can all influence how much space the tire has during steering and suspension movement.
That matters because a size that is correct on paper still needs room to operate on the actual vehicle. Any truck with custom hardware should be checked for wheel diameter, wheel width, clearance at full lock, and interference points near the fenders or suspension before replacement tires are put into service.
What should I inspect before driving a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG on new tires?
Before road use, inspect tire pressure, bead seating, visible sidewall condition, tread surfaces, and lug hardware on the mounted wheels. On a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG, it also makes sense to confirm that the 325/55R22 tires have adequate clearance around the suspension and body through the steering range.
A quick walkaround is not enough on a vehicle with this kind of height and tire scale. Recheck inflation after the first drives, watch for rubbing or unusual wear, and make sure the truck tracks normally. Any vibration, air loss, or contact marks deserve attention before extended road use.
How often should tires on a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG be inspected?
Tires on a 2023 Mercedes-Benz Trucks G63 4x4 Squared AMG should be inspected regularly, not just when tread looks low. Pressure, cuts, bulges, cracking, irregular wear, and signs of air loss are all worth checking, especially on a vehicle with large, visually exposed tires where small issues can become easier to miss in daily use.
A monthly inspection is a sensible habit, with an extra check before longer trips or after the truck has been parked for extended periods. Low-use specialty vehicles can age their tires without accumulating many miles, so condition matters just as much as tread depth when deciding whether the tires remain roadworthy.
