The 2015 Mercedes-Benz Trucks G63 AMG blends the long-running G-Class shape with modern AMG performance, giving this hand-built SUV a very different mission from the utilitarian roots that made the platform famous. Its upright body, substantial curb presence, and high-output character make tire choice especially important to both appearance and road manners. This model uses a 275/50R20 radial tire on a 20-inch rim. Because there is one primary fitment, the focus shifts from identifying size to choosing the right tire within that size and confirming wheel compatibility on any modified vehicle. That matters whether the goal is maintaining the stock-style stance or preparing the truck for confident street use.
Which Tire Size Is Right for The 2015 Mercedes-Benz Trucks G63 AMG
The 2015 Mercedes-Benz Trucks G63 AMG uses one primary tire size: 275/50R20 in radial construction on a 20-inch rim. The Base sub-model uses that same fitment, so the main decision is not which size applies, but which 275/50R20 tire best suits the vehicle's wheel setup, intended use, and overall presentation.
The size 275/50R20 identifies a metric radial tire that is 275 millimeters wide, uses a 50-series aspect ratio, and mounts on a 20-inch wheel. On the 2015 Mercedes-Benz Trucks G63 AMG, that modern radial sizing matches the vehicle's contemporary performance-oriented character and substantial wheel package. This format is familiar to late-model SUV owners and centers the selection process on proper wheel compatibility, overall tire condition, and the intended balance of appearance and street use. It is the fitment to confirm first before comparing product details or evaluating any changes made to wheels or suspension.
Sub-model fitment is straightforward for this vehicle. The covered G63 AMG configuration uses the same primary tire size, so confirming the exact sub-model mainly helps ensure the wheel and tire setup has not been changed from its expected 20-inch radial fitment.

Frequently Asked Questions
These FAQs for the 2015 Mercedes-Benz Trucks G63 AMG focus on 275/50R20 fitment, 20-inch rim considerations, tire selection factors, and the checks worth making before putting a high-performance luxury SUV back on the road.
Tire Size & Fitment
What tire size fits a 2015 Mercedes-Benz Trucks G63 AMG?
The 2015 Mercedes-Benz Trucks G63 AMG uses a 275/50R20 radial tire. That is the primary fitment for this model and it matches a 20-inch wheel diameter, making it the starting point for any replacement tire search on this exact vehicle.
Size should still be confirmed against the truck's actual wheel setup before ordering, especially if it has aftermarket wheels or previous suspension changes. Even when the vehicle is a G63 AMG, wheel width, offset, and clearance around the fenders and steering components still matter when selecting a new 275/50R20 tire.
What size rim does a 2015 Mercedes-Benz Trucks G63 AMG use?
The primary tire fitment for the 2015 Mercedes-Benz Trucks G63 AMG is built around a 20-inch rim. That rim diameter is reflected directly in the 275/50R20 tire size, where the final number indicates the wheel diameter the tire is designed to mount on.
Rim diameter is only one part of the fitment picture, so it is smart to verify the wheel's actual width and overall setup as well. A 20-inch wheel that differs in width or offset from the intended setup can affect clearance, stance, and how the tire sits on the vehicle.
Does the 2015 Mercedes-Benz Trucks G63 AMG Base use the same tire size?
Yes. The 2015 Mercedes-Benz Trucks G63 AMG Base uses the same 275/50R20 radial tire size as the core model fitment. That makes sub-model selection straightforward, since there is no alternate primary size to sort through for the Base configuration.
The practical next step is confirming that the truck still carries its expected 20-inch wheel setup. A previous owner may have changed wheels, ride height, or tire sizing, and those changes can alter what works in service even when the original G63 AMG Base fitment is clear.
Choosing the Right Tire
What should I consider when choosing a 275/50R20 tire for a 2015 Mercedes-Benz Trucks G63 AMG?
Start with the correct 275/50R20 size and confirm that the tire is intended for a 20-inch wheel. From there, the key considerations are wheel compatibility, the truck's current setup, and how the vehicle will be used, since a G63 AMG places different demands on tires than a lightly driven collector SUV.
A careful buyer should also inspect whether the truck remains at stock ride height and factory-style wheel dimensions. Changes in offset, wheel width, or suspension position can influence clearance at the fenders and steering range, so those details matter before settling on any new 275/50R20 tire.
How do I choose between the available 275/50R20 tires for a 2015 Mercedes-Benz Trucks G63 AMG?
The best way to narrow the choice is to keep the correct size first and then compare tires by the demands of the vehicle. On a 2015 Mercedes-Benz Trucks G63 AMG, that means looking at overall wheel compatibility, intended street use, and whether the vehicle is expected to preserve a stock-style appearance.
Selection also becomes easier when the truck is evaluated as it sits today rather than as-built years ago. A vehicle with non-original wheels, altered suspension, or visible clearance limits around the inner fenders may need extra attention, even though 275/50R20 remains the proper fitment size to begin with.
What rim-fitment details should I compare when choosing 2015 Mercedes-Benz Trucks G63 AMG tires?
The first rim-fitment detail is diameter, because the 2015 Mercedes-Benz Trucks G63 AMG uses a 20-inch wheel with its 275/50R20 tire size. After that, wheel width and offset become important because they affect how the tire sits, clears suspension components, and tracks through full steering movement.
Those checks matter even more on a performance SUV with a wide tire footprint. A tire can match the correct diameter and still create problems if the wheel dimensions are not appropriate, so the wheel itself should be inspected closely before mounting replacement tires for regular road use.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Mercedes-Benz Trucks G63 AMG?
A period-style approach on a 2015 Mercedes-Benz Trucks G63 AMG starts with keeping the original fitment format intact, which means staying with the 275/50R20 radial size on a 20-inch wheel. Because this is a modern AMG-era vehicle, preserving the correct size and stance usually matters more than chasing older-style construction themes.
Appearance should still be judged alongside the truck's actual condition and intended use. A G63 AMG that retains its expected wheel setup will usually benefit from a tire that supports its original visual proportion, while heavily modified examples should be checked carefully so the stance does not come at the expense of clearance.
Does correct tire fitment matter for a 2015 Mercedes-Benz Trucks G63 AMG restoration?
Yes, correct tire fitment matters because the 2015 Mercedes-Benz Trucks G63 AMG was built around a specific modern radial size, 275/50R20. The right size helps preserve the vehicle's intended visual balance and keeps the wheel-and-tire package aligned with the way this AMG luxury SUV was meant to sit on the road.
For restoration-minded owners, that makes fitment accuracy more useful than improvising with a similar-looking size. Any departure from the expected wheel diameter or tire profile should be checked closely against the vehicle's current wheels, suspension, and body clearance so the finished truck looks right and remains usable.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Mercedes-Benz Trucks G63 AMG?
Yes. Modifications can change how a 275/50R20 tire fits on a 2015 Mercedes-Benz Trucks G63 AMG, even when the size itself is correct for the model. Aftermarket wheels, altered offset, suspension changes, lowering, or body modifications can all influence steering clearance, fender clearance, and the tire's position in the wheel opening.
That is why the current vehicle setup should be inspected before replacing tires. A G63 AMG that no longer uses its expected wheel dimensions may need more than a simple size match, and checking clearance at full lock and full suspension travel can prevent unwanted rubbing or uneven wear.
What should I inspect before driving a 2015 Mercedes-Benz Trucks G63 AMG on new tires?
Before road use, inspect tire pressure, wheel fastener security, visible clearance around the suspension and fenders, and the general condition of the wheels themselves. It is also smart to look over the old tires that came off the vehicle, since uneven wear can point to alignment or suspension issues on the 2015 Mercedes-Benz Trucks G63 AMG.
A short, careful test drive helps confirm that the new tires track properly and do not contact body or steering components. Any vibration, pull, unusual noise, or rubbing should be addressed immediately, particularly on a heavy, high-performance SUV where tire behavior can reveal setup issues quickly.
How often should tires on a 2015 Mercedes-Benz Trucks G63 AMG be inspected?
Tires on a 2015 Mercedes-Benz Trucks G63 AMG should be inspected regularly rather than only when replacement becomes obvious. Frequent checks for pressure loss, cuts, bulges, abnormal tread wear, and sidewall damage are especially important on a vehicle that may see periods of storage mixed with spirited road use.
Inspection should also become routine before longer drives or after the truck has been sitting. Vehicles that are used less often can still develop flat spotting, aging concerns, or pressure changes over time, so a quick walkaround and pressure check can make a meaningful difference before heading out.
