Mercedes-Benz Trucks G63 AMG Tires

Mercedes-Benz Trucks G63 AMG blends the long-running G-Class off-road shape with modern AMG performance, creating a high-powered luxury utility vehicle produced here from 2013 through 2026. That combination matters because the G63 AMG sits at the intersection of rugged truck-like design and increasingly aggressive wheel and tire packages as the years progress. Tire selection is not completely straightforward, since later Mercedes-Benz Trucks G63 AMG years show multiple fitment choices and a clear shift in wheel diameter across the production run. The first step is to confirm whether the specific Mercedes-Benz Trucks G63 AMG carries 20-inch, 21-inch, or 22-inch wheels before choosing a replacement tire size.

Mercedes-Benz Trucks G63 AMG Tire Size Guide

Mercedes-Benz Trucks G63 AMG production changed from 20-inch to 21-inch wheels in 2018, and 22-inch fitments appear from 2019 onward, so wheel diameter is the first thing to verify on the vehicle itself. Across the 2013 to 2026 production span, this model group uses 4 distinct tire sizes. All of the sizes listed here are metric radial sizes, with the first number showing section width in millimeters, the second number showing aspect ratio, and the last number showing rim diameter in inches.

275/50R202013-2026Metric radial

275/50R20 is the longest-running Mercedes-Benz Trucks G63 AMG size and appears from 2013 through 2026 on versions equipped with 20-inch wheels. In this metric radial code, 275 is the section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 20 is the required rim diameter in inches. Choose this size for Mercedes-Benz Trucks G63 AMG models that retain the 20-inch wheel package, especially when matching the earlier production fitment or a later truck still riding on 20-inch rims.

295/35R212018Metric radial

295/35R21 is a one-year Mercedes-Benz Trucks G63 AMG fitment used in 2018 on 21-inch wheel applications. In this metric radial code, 295 is the section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 21 is the required rim diameter in inches. Choose this size only for a 2018 Mercedes-Benz Trucks G63 AMG that is already fitted with the 21-inch wheel package, since it does not interchange with the 20-inch or 22-inch options.

285/45R212019-2026Metric radial

285/45R21 fits Mercedes-Benz Trucks G63 AMG models from 2019 through 2026 when equipped with 21-inch wheels. In this metric radial code, 285 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 21 is the required rim diameter in inches. Choose this size for later Mercedes-Benz Trucks G63 AMG applications using the 21-inch package, and verify the wheel itself because the same model years can also carry 20-inch or 22-inch fitments.

295/40R222019-2026Metric radial

295/40R22 appears on Mercedes-Benz Trucks G63 AMG models from 2019 through 2026 with the largest wheel option in this listing. In this metric radial code, 295 is the section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 22 is the required rim diameter in inches. Choose this size only for Mercedes-Benz Trucks G63 AMG models already running 22-inch wheels, since later years list multiple wheel diameters under the same model year.

If your Mercedes-Benz Trucks G63 AMG is from 2019 or later, identify the specific wheel package before selecting a tire, because those years split across 20-inch, 21-inch, and 22-inch fitments.

Mercedes-Benz Trucks G63 AMG Tires by Year

Mercedes-Benz Trucks G63 AMG production changed from 20-inch to 21-inch wheels in 2018, and 22-inch wheels appear from 2019 onward, so confirm which rim diameter the specific truck carries before selecting a tire. In 2019, 2020, 2021, 2022, 2023, 2024, 2025, and 2026, more than two sizes are listed because the model spans multiple wheel-diameter packages. Use the year listing to narrow the range first, then match the tire size to the actual wheel diameter on the vehicle.

Frequently Asked Questions

The FAQ below focuses on the wheel-diameter changes that shape Mercedes-Benz Trucks G63 AMG tire selection, along with practical guidance for sorting 20-inch, 21-inch, and 22-inch fitments across overlapping model years.

Size Basics & Fitment

Mercedes-Benz Trucks G63 AMG uses four tire sizes across the 2013 to 2026 span: 275/50R20 for 2013 through 2026, 295/35R21 for 2018, 285/45R21 for 2019 through 2026, and 295/40R22 for 2019 through 2026. Those sizes correspond to 20-inch, 21-inch, and 22-inch wheel diameters, with later years carrying more than one wheel package under the same model name.

The practical takeaway is that the model year alone is not always enough to identify the correct tire. Start with the year, then verify the wheel diameter on the truck and confirm the exact size shown on the current tire placard or wheel-and-tire setup before choosing a replacement.

A 2019 Mercedes-Benz Trucks G63 AMG can have three tire sizes listed because that model year spans three different wheel-diameter packages: 275/50R20 on 20-inch wheels, 285/45R21 on 21-inch wheels, and 295/40R22 on 22-inch wheels. The split is driven by rim diameter rather than by interchangeable tire sizing on one wheel.

That means you should not choose a tire by year alone if you own a 2019 Mercedes-Benz Trucks G63 AMG. Check the wheel diameter stamped on the rim or read the complete size from the tire already mounted, then match the replacement size to that wheel package.

Mercedes-Benz Trucks G63 AMG uses 20-inch, 21-inch, and 22-inch rim diameters in this year range. The early run from 2013 through 2017 stays with 20-inch wheels, 21-inch fitment appears in 2018, and from 2019 onward the model can be found with 20-inch, 21-inch, or 22-inch wheels depending on configuration.

Wheel diameter is the first fitment checkpoint because none of these tire sizes cross over between rim diameters. If you are comparing a later Mercedes-Benz Trucks G63 AMG to an earlier one, confirm the wheel size before looking at width or aspect ratio.

Buying the Right Tire

A 2024 Mercedes-Benz Trucks G63 AMG can use 275/50R20, 285/45R21, or 295/40R22, so the correct size depends on the wheel package installed on that specific truck. All three sizes belong to the same model year, but each one is tied to a different rim diameter.

Check the size molded into the current tire sidewall and confirm the wheel diameter before replacing anything. If the truck has changed hands or has had wheels swapped, that physical verification matters more than assuming every 2024 Mercedes-Benz Trucks G63 AMG used the same tire.

No product brands are listed here for Mercedes-Benz Trucks G63 AMG tires. The fitment information on this page centers on the size range used across the production years rather than on a brand breakdown.

Use the size and wheel-diameter information first, because choosing the correct fitment is more important than starting with a brand name. Once the proper size is confirmed for your Mercedes-Benz Trucks G63 AMG, you can narrow the search by performance category, sidewall profile, and intended road use.

No tire series are identified here for Mercedes-Benz Trucks G63 AMG applications. The key distinctions in this fitment set are size, aspect ratio, and wheel diameter rather than named vintage-style construction families.

For a modern Mercedes-Benz Trucks G63 AMG, the practical comparison is between the 20-inch, 21-inch, and 22-inch fitments and how each affects sidewall height. The 20-inch size carries a taller sidewall than the 21-inch and 22-inch options, while the larger-diameter wheel packages move toward a lower-profile look and feel.

Maintenance & Longevity

A Mercedes-Benz Trucks G63 AMG should be stored on a clean, dry surface away from direct sunlight, ozone sources, and extreme temperature swings. Keep the tires properly inflated, avoid long-term exposure to petroleum products, and move the truck periodically if it will sit for extended periods.

Because Mercedes-Benz Trucks G63 AMG uses large-diameter, lower-profile radial tires in some configurations, flat-spotting and sidewall stress are worth watching during storage. If the truck is parked for months at a time, regular pressure checks and occasional repositioning help preserve ride quality and casing condition.

Tires on a Mercedes-Benz Trucks G63 AMG should be inspected at least monthly and again before any longer drive. Check inflation pressure, tread wear pattern, sidewall condition, and any signs of impact damage, especially on the lower-profile 21-inch and 22-inch fitments.

Frequent inspection matters because an aging collector or specialty-use vehicle may sit for long intervals and then return to service suddenly. On a Mercedes-Benz Trucks G63 AMG, catching pressure loss or sidewall damage early can prevent uneven wear and protect expensive wheel packages from avoidable damage.

Tires on a Mercedes-Benz Trucks G63 AMG should be replaced when they show age cracking, impact damage, bulges, persistent air loss, or other structural concerns even if the tread still looks usable. Tread depth alone is not the full measure of serviceability on a low-mileage or intermittently driven vehicle.

A Mercedes-Benz Trucks G63 AMG that spends long periods parked can age its tires before wearing them out. If there is any question about age or condition, especially on a truck with large wheels and short sidewalls, a professional inspection is the right next step before further road use.

Safety & Road Use

A Mercedes-Benz Trucks G63 AMG can be driven safely on public roads when the tires are the correct size for the wheel, are in sound condition, and are maintained at appropriate pressure. The main fitment risk in this application is selecting a tire for the wrong wheel diameter, since 20-inch, 21-inch, and 22-inch packages all appear in the same later model years.

Before regular road use, inspect the tires for age-related deterioration, damage, and uneven wear, then confirm that all four match the intended setup. On a Mercedes-Benz Trucks G63 AMG, safety starts with correct fitment and condition rather than with model year alone.

Before driving a Mercedes-Benz Trucks G63 AMG, check tire pressure, visible sidewall condition, tread wear, and the overall integrity of the wheel-and-tire package. Also confirm that the truck is riding on the correct tire size for its installed wheel diameter, particularly on 2019 and later models where multiple fitments are possible.

A quick walkaround can prevent the most common problems, including underinflation, impact damage, and mismatched fitment. If the Mercedes-Benz Trucks G63 AMG has aftermarket wheels or a recent wheel swap, give that verification extra attention before heading onto the road.

A Mercedes-Benz Trucks G63 AMG should only be driven at speeds appropriate for the exact tire fitted, its condition, and its load. Since multiple tire sizes and wheel packages are used across these years, the safe operating envelope depends on the specific tire installed rather than on the model name alone.

The sensible approach is to avoid assuming that every Mercedes-Benz Trucks G63 AMG tire setup behaves the same way at speed. Match your road use to the tire's service rating and current condition, and treat older or suspect tires conservatively until they have been fully inspected.
