The 2017 Mercedes-Benz Trucks G63 AMG blends the long-running G-Class off-road shape with modern AMG performance, giving it a very different character from earlier utility-focused Geländewagen models. By this point, the appeal was as much about presence, power, and everyday luxury as trail heritage. Tire fitment is straightforward here, with a single primary size: 275/50R20 radial. That keeps the focus on selecting the right tire within the correct size rather than sorting through multiple factory fitments. For an owner, the important next steps are confirming the 20-inch wheel setup on the vehicle and choosing a tire that suits its current use, appearance goals, and overall condition.
Which Tire Size Is Right for The 2017 Mercedes-Benz Trucks G63 AMG
The 2017 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 this same fitment, so the main decision is not which primary size applies, but how to confirm the wheel setup on the vehicle and choose the right tire within that size for its intended use.
275/50R20 is a modern metric radial size in which 275 identifies the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2017 Mercedes-Benz Trucks G63 AMG, this size matches the vehicle's contemporary high-performance luxury 4x4 character and its 20-inch wheel fitment. Modern metric sizing is familiar to late-model buyers and makes it easier to compare replacement tires within the same general dimensions. The practical priority is confirming that the vehicle still has the correct wheel diameter and a compatible overall setup before choosing a replacement tire.
Fitment is simple across the covered 2017 Mercedes-Benz Trucks G63 AMG sub-models, because the same primary tire size is used throughout. Checking the exact sub-model still helps confirm that the vehicle has not been changed to a different wheel or tire package over time.

Frequently Asked Questions
These FAQs focus on 2017 Mercedes-Benz Trucks G63 AMG tire size, 20-inch rim fitment, radial construction, selection considerations, and the checks that matter before putting a high-performance luxury SUV back on the road.
Tire Size & Fitment
What tire size fits a 2017 Mercedes-Benz Trucks G63 AMG?
The 2017 Mercedes-Benz Trucks G63 AMG uses a 275/50R20 tire size. This is a radial tire mounted on a 20-inch rim, and it is the primary fitment for the covered model.
That makes the buying decision fairly straightforward, but it is still important to confirm what is actually on the vehicle before replacing tires. If the G63 AMG has aftermarket wheels, a suspension change, or a previous owner-installed tire package, the current setup may differ from the original size and wheel diameter.
What size rim does a 2017 Mercedes-Benz Trucks G63 AMG use?
The 2017 Mercedes-Benz Trucks G63 AMG uses a 20-inch rim with its 275/50R20 tire size. In the size code itself, the final number, 20, identifies the wheel diameter in inches.
Wheel diameter is the first thing to verify before ordering replacement tires, especially on a vehicle that may have seen custom wheel upgrades. A tire built for a different rim diameter cannot be used safely, so checking the wheel markings and confirming the full tire size already mounted on the SUV is a smart first step.
Does the 2017 Mercedes-Benz Trucks G63 AMG Base use the same tire size?
Yes. The 2017 Mercedes-Benz Trucks G63 AMG Base uses the same 275/50R20 radial tire size. There is no separate primary size here for the Base sub-model.
That consistency simplifies replacement planning, because there is no need to sort through multiple stock tire sizes by trim. The practical check is making sure the vehicle still carries its proper 20-inch wheel setup and that no wheel, brake, or suspension changes have altered the space available for the tire currently on the truck.
Choosing the Right Tire
What should I consider when choosing a 275/50R20 tire for a 2017 Mercedes-Benz Trucks G63 AMG?
Start with the correct size and construction: 275/50R20 radial on a 20-inch wheel. From there, compare the tire's intended use, overall design character, and compatibility with the wheel and vehicle setup already on the G63 AMG.
This model blends heavy-duty SUV proportions with AMG performance, so replacement tires should be chosen with both fitment and use in mind. Confirm the actual wheel size on the vehicle, check for any modifications, and inspect for clearance around suspension and body components before settling on a specific tire in this size.
How do I choose between available 275/50R20 tires for a 2017 Mercedes-Benz Trucks G63 AMG?
Choose between 275/50R20 tires by first matching the exact size, then comparing how each option suits the vehicle's role. A G63 AMG used mainly on pavement may call for a different tire character than one expected to see mixed-use driving or more aggressive conditions.
It also helps to look at the vehicle as it sits today. Factory-style wheels, custom wheels, suspension changes, and appearance priorities can all influence which tire feels most appropriate. Staying with the correct size keeps the fitment question narrow, while careful comparison helps avoid selecting a tire that clashes with the truck's current setup.
What rim-fitment details should I compare when choosing tires for a 2017 Mercedes-Benz Trucks G63 AMG?
The key rim-fitment detail is wheel diameter, and for the 2017 Mercedes-Benz Trucks G63 AMG that means a 20-inch wheel to match 275/50R20 tires. Beyond diameter, the actual wheel dimensions and the vehicle's present hardware still matter when comparing replacement options.
Owners should confirm that the wheels on the vehicle are the expected size and not an aftermarket substitute with different width or offset characteristics. That becomes especially important on a high-profile, modified, or custom-finished G-Class, where small wheel changes can affect clearance, steering feel, and the way the tire sits within the fender opening.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Mercedes-Benz Trucks G63 AMG?
A period-style approach on a 2017 Mercedes-Benz Trucks G63 AMG starts by staying with the correct 275/50R20 radial size and 20-inch wheel fitment. Since this is a modern AMG-era vehicle, the right look usually comes from preserving the intended proportions rather than moving to an older vintage tire style.
Appearance still depends on the vehicle's exact presentation. A stock-looking G63 AMG, a customized truck, and a collector-kept example may call for different visual priorities even within the same size. The most useful path is to keep the proper dimensions first, then choose a tire that complements the SUV's existing wheels and stance.
Does correct tire fitment matter for a 2017 Mercedes-Benz Trucks G63 AMG restoration?
Yes, correct tire fitment matters because the 2017 Mercedes-Benz Trucks G63 AMG has a very specific visual and mechanical presence built around its 275/50R20 radial size. Changing size or wheel diameter can quickly alter the stance, fender fill, and overall look of the vehicle.
Fitment also affects more than appearance. A restoration-oriented owner should verify wheel diameter, check the current suspension height, and make sure the tire remains appropriate for the truck's actual configuration. On a newer collectible like this one, keeping the dimensions consistent is often the cleanest way to preserve the vehicle's character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz Trucks G63 AMG?
Yes. Modifications can change how a 275/50R20 tire fits on a 2017 Mercedes-Benz Trucks G63 AMG, even when the size itself remains the same. Wheel offset changes, wider aftermarket wheels, suspension lifts or lowering, and body alterations can all affect clearance.
That is why it is important to inspect the vehicle as it sits now rather than assuming every G63 AMG still has its original configuration. Check steering clearance, inner fender space, and the relationship between the tire and suspension components before mounting new tires, especially if the truck has been customized for appearance or performance.
What should I inspect before driving a 2017 Mercedes-Benz Trucks G63 AMG on new tires?
Before driving, inspect the wheels for the correct 20-inch diameter, confirm the new tires are the proper 275/50R20 size, and check inflation, valve condition, and visible seating on the rim. It is also wise to look over the suspension and steering for obvious wear or looseness.
A short, careful road check helps confirm that nothing rubs at full steering lock or over suspension movement. On a high-performance SUV like the G63 AMG, uneven wear, vibration, or pull should be addressed early, since those symptoms can point to alignment, wheel, or suspension issues rather than the tire alone.
How often should tires on a 2017 Mercedes-Benz Trucks G63 AMG be inspected?
Tires on a 2017 Mercedes-Benz Trucks G63 AMG should be inspected regularly, not just when tread looks low. Pressure, tread wear, sidewall condition, and any signs of cuts, bulges, or cracking are worth checking before routine use and especially before longer trips.
Collector-owned or lightly driven vehicles deserve extra attention because tire age and storage conditions can matter as much as mileage. A G63 AMG that spends long periods parked should still have its tires checked for air loss, flat spotting, and age-related deterioration, with the vehicle stored away from prolonged heat, sunlight, and ozone sources.
