The 2013 Mercedes-Benz Trucks G63 AMG blends the long-running G-Class off-road shape with the more aggressive character and road presence expected from AMG. Even with its upright, utility-rooted design, tire choice on this vehicle is centered on a modern performance-oriented fitment rather than a vintage sizing system. The 2013 Mercedes-Benz Trucks G63 AMG uses a 275/50R20 radial tire, putting the focus on matching the correct metric size and 20-inch wheel diameter. That makes the main decision less about decoding multiple fitments and more about selecting the right radial tire for appearance, road use, and the actual wheel setup on the truck.
Which Tire Size Is Right for The 2013 Mercedes-Benz Trucks G63 AMG
The 2013 Mercedes-Benz Trucks G63 AMG uses one primary tire size: 275/50R20. It is a radial fitment on a 20-inch rim, and the covered Base sub-model uses that same size, so the key step is confirming that the truck still has the proper 20-inch wheel setup before choosing a tire within that specification.
275/50R20 is a metric radial size. The 275 indicates nominal section width in millimeters, the 50 is the aspect ratio, the R identifies radial construction, and the 20 is the wheel diameter in inches. On the 2013 Mercedes-Benz Trucks G63 AMG, this size keeps tire selection in a modern format familiar to current buyers rather than an older bias-ply or alphanumeric system. The practical goal is to stay with the correct size and verify the actual wheel dimensions and vehicle clearance if the truck has had wheel, suspension, or stance changes over time.
Fitment is straightforward across the covered 2013 Mercedes-Benz Trucks G63 AMG sub-models. The tire size remains consistent, so checking the sub-model is mainly a way to confirm that the truck still matches its original wheel and tire configuration.

Frequently Asked Questions
Common questions for the 2013 Mercedes-Benz Trucks G63 AMG usually center on the 275/50R20 tire size, 20-inch rim fitment, radial-tire selection, and what to inspect before driving a heavy, high-performance luxury truck on fresh or existing tires.
Tire Size & Fitment
What tire size fits a 2013 Mercedes-Benz Trucks G63 AMG?
The 2013 Mercedes-Benz Trucks G63 AMG uses a 275/50R20 radial tire. That is the primary fitment for this vehicle and it matches a 20-inch wheel diameter, which makes the size itself the starting point for any replacement search.
The next step is confirming that the truck still has the correct wheel setup, especially if a previous owner changed wheels or altered the suspension. Staying with the proper size helps preserve the intended relationship between tire width, sidewall height, and wheel diameter while avoiding unnecessary clearance and fitment guesswork.
What size rim does a 2013 Mercedes-Benz Trucks G63 AMG use?
The 2013 Mercedes-Benz Trucks G63 AMG uses a 20-inch rim with its 275/50R20 tire size. In practical terms, the tire is built around a 20-inch wheel diameter, so matching that diameter is essential before comparing replacement tires.
Wheel diameter should be checked directly on the vehicle if there is any doubt about modifications. A truck that has been changed to a different wheel size may require a different tire size, and simply selecting a 275/50R20 without confirming the current wheels can create an immediate mismatch between tire and rim.
Does the 2013 Mercedes-Benz Trucks G63 AMG Base use the same tire size?
Yes. The 2013 Mercedes-Benz Trucks G63 AMG Base uses the same 275/50R20 radial tire size as the covered model fitment. That keeps selection simple because there is no separate alternate size to sort through at the sub-model level.
Even with consistent sub-model sizing, it still helps to inspect the actual truck before ordering tires. Aftermarket wheels, previous tire substitutions, or suspension changes can alter what is currently installed, so the smartest approach is to confirm the wheel diameter and compare the existing setup against the intended 275/50R20 fitment.
Choosing the Right Tire
What should I consider when choosing a 275/50R20 tire for a 2013 Mercedes-Benz Trucks G63 AMG?
Start with the correct size: 275/50R20 on a 20-inch wheel. Since this truck uses a radial tire in a modern metric format, the main selection factors are keeping the proper sizing, matching the wheel diameter, and choosing a tire suited to how the vehicle is actually driven and presented.
It also helps to compare the truck's current wheel setup and overall condition before making a final choice. A G63 AMG that remains close to stock may call for a different approach than one with aftermarket wheels or stance changes, and a careful check of clearance, load needs, and road-use expectations makes the selection more reliable.
How do I choose between the available 275/50R20 tires for a 2013 Mercedes-Benz Trucks G63 AMG?
The best comparison points are size accuracy, radial construction, wheel compatibility, and the role the truck plays in your garage. A mostly road-driven G63 AMG may lead you toward one kind of replacement decision, while a truck focused on appearance or occasional-use storage may shift the priority toward a different balance of look and use.
Selection becomes easier when the current setup is inspected first. Looking at the existing tire wear, confirming the wheels have not been changed, and deciding whether originality of appearance or everyday drivability matters more will narrow the field without relying on guesswork or choosing a tire that only matches the size on paper.
Why is the 275/50R20 size important on a 2013 Mercedes-Benz Trucks G63 AMG?
The 275/50R20 size is important because it defines the tire's width, sidewall profile, radial construction, and required 20-inch wheel diameter. On a vehicle like the 2013 Mercedes-Benz Trucks G63 AMG, that combination plays a major role in how the truck sits, clears the body, and matches the wheel size it was built around.
Changing away from that specification without a full fitment review can affect more than appearance. The owner should verify current wheel dimensions, inspect steering and fender clearance, and consider whether any suspension or wheel modifications have already altered the truck before deciding to remain with the original size or explore a different setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Mercedes-Benz Trucks G63 AMG?
Yes. Modifications can affect tire fitment on a 2013 Mercedes-Benz Trucks G63 AMG even when the original size is 275/50R20. Changes to wheel diameter, wheel width, offset, ride height, or suspension components can alter how much room the tire has at the fender, steering components, and inner wheelhouse.
A modified truck should be checked carefully before any replacement purchase. Measuring the current wheels, inspecting clearance at full steering lock, and looking for rubbing marks or uneven tire wear will give a much clearer picture than relying only on the original fitment size, especially on a vehicle that may have changed hands more than once.
What should I inspect before driving a 2013 Mercedes-Benz Trucks G63 AMG on new tires?
Before driving on new tires, inspect the wheels for damage, confirm the tire size matches 275/50R20, and make sure the tires are mounted on the correct 20-inch rims. It is also wise to look over valve stems, check inflation, and verify that there is no immediate interference with suspension or body components.
A short test drive should be followed by another visual inspection. Watching for rubbing, listening for contact at low-speed turns, and checking that the truck tracks normally can catch setup problems early. On a heavy, high-performance vehicle, small fitment issues are worth addressing right away before they become wear, handling, or clearance problems.
How often should tires on a 2013 Mercedes-Benz Trucks G63 AMG be inspected?
Tires on a 2013 Mercedes-Benz Trucks G63 AMG should be inspected regularly, especially if the truck sees occasional use, long periods of storage, or mixed driving conditions. Routine checks should include tread wear, sidewall cracking, cuts, bulges, punctures, and any sign of slow air loss.
Collector-minded or low-mileage vehicles can still develop tire problems even when tread looks good. A monthly pressure check and a closer inspection before longer drives help catch age-related issues, flat spotting, or damage from storage. That habit matters on a vehicle with large 20-inch tires, where weight and performance can make condition problems show up quickly.
