The 2022 Mercedes-Benz Trucks G550 carries the long-running G-Class formula into the modern era with serious off-road hardware, upright styling, and the kind of road presence that makes wheel and tire choice especially noticeable. On this exact model, tire selection starts with confirming which wheel package is on the truck, because three radial sizes apply: 265/60R18, 275/55R19, and 275/50R20. That means the real decision is not vintage bias-ply versus radial, but matching the correct rim diameter and choosing a tire that suits the vehicle’s intended look and use. For any G550, wheel size, overall dimensions, and clearance should be checked before replacement.
Which Tire Size Is Right for The 2022 Mercedes-Benz Trucks G550
The 2022 Mercedes-Benz Trucks G550 uses three primary tire sizes, and the right one depends first on the wheel diameter already on the vehicle. All three are metric radial sizes, but they pair with different 18-inch, 19-inch, or 20-inch rims, so confirming the actual wheel setup is the first step before comparing tire choices.
A 265/60R18 tire uses a 265-millimeter section width, a 60-series aspect ratio, radial construction, and an 18-inch rim. On the 2022 Mercedes-Benz Trucks G550, this size is part of the vehicle’s modern radial fitment rather than an older bias-ply sizing system. Its dimensions place it in the same general height range as the other G550 fitments while using the smallest rim diameter of the three. This size should be chosen only when the vehicle is already equipped with 18-inch wheels or when a verified wheel-and-clearance plan supports that setup.
A 275/50R20 tire combines a 275-millimeter section width with a 50-series profile, radial construction, and a 20-inch rim. For the 2022 Mercedes-Benz Trucks G550, it represents the largest wheel-diameter fitment among the three primary sizes. The lower profile compared with the other G550 sizes changes the tire’s visual balance by placing more emphasis on the wheel. This size makes sense only for a G550 running 20-inch wheels, and buyers should confirm wheel dimensions and surrounding clearance before moving into product selection.
A 275/55R19 tire has a 275-millimeter section width, a 55-series sidewall profile, radial construction, and a 19-inch rim. On the 2022 Mercedes-Benz Trucks G550, this size sits between the 18-inch and 20-inch options in rim diameter while staying close to them in overall tire height. That makes it a distinct fitment tied to the wheel package rather than a casual substitute for the other two sizes. It should be evaluated as the correct choice for a G550 already using 19-inch wheels, with wheel width and clearance checked before replacement.
Fitment is straightforward at the sub-model level because the 2022 Mercedes-Benz Trucks G550 Base is associated with all three primary tire sizes. The key is not trim identification so much as confirming which wheel diameter the vehicle actually has before selecting a replacement tire.

Frequently Asked Questions
Owners usually need to confirm the correct G550 wheel diameter first, then sort out size meaning, rim fitment, replacement strategy, and basic road-use checks for a modern collector-grade luxury 4x4.
Tire Size & Fitment
What tire size fits a 2022 Mercedes-Benz Trucks G550?
A 2022 Mercedes-Benz Trucks G550 uses one of three radial tire sizes: 265/60R18, 275/55R19, or 275/50R20. Those sizes are all associated with the G550 Base, so the correct choice depends on which wheel diameter is on the vehicle rather than on a separate trim-level split.
The most important step is checking the wheel itself before ordering tires. An 18-inch tire will not work on a 19-inch or 20-inch rim, even though the overall tire heights are fairly close. If the vehicle has had aftermarket wheel changes, confirm the actual wheel diameter and width on the truck rather than relying on assumptions.
What size rim does a 2022 Mercedes-Benz Trucks G550 use?
The 2022 Mercedes-Benz Trucks G550 uses 18-inch, 19-inch, or 20-inch rims, depending on which of its three primary tire sizes is installed. The matching tire sizes are 265/60R18 for 18-inch rims, 275/55R19 for 19-inch rims, and 275/50R20 for 20-inch rims.
Rim diameter is the first fitment checkpoint because the tire bead must match the wheel exactly. Once that is confirmed, it is also worth checking wheel width, especially on a vehicle that may have been modified. A replacement tire should be selected around the real wheel setup and the space available at the fenders, steering, and suspension.
Why does the 2022 Mercedes-Benz Trucks G550 have more than one tire size?
The 2022 Mercedes-Benz Trucks G550 has more than one tire size because it is associated with multiple wheel diameters. Its primary fitments include 265/60R18, 275/55R19, and 275/50R20, all of them radial sizes and all tied to different wheel packages rather than to a change from bias-ply to radial construction.
That means the right replacement is determined by the wheel package already on the truck. The sizes are close in overall height, but they are not interchangeable by default because each one is built around a different rim diameter. Any G550 with aftermarket wheels, suspension changes, or nonstandard offsets deserves a fresh measurement before tire selection.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Mercedes-Benz Trucks G550?
Start with the exact tire size already fitted to the vehicle: 265/60R18, 275/55R19, or 275/50R20. On a 2022 Mercedes-Benz Trucks G550, correct sizing comes before any other decision because all three are primary radial fitments, but each one is built for a different wheel diameter.
After confirming the size, focus on how the G550 is actually used. Daily road use, occasional off-pavement driving, and appearance goals can all influence the type of tire you want within that size. It also makes sense to inspect wheel width, current clearance, and any modifications so the replacement matches the vehicle’s real-world setup rather than an assumed stock configuration.
How do I choose between the available 2022 Mercedes-Benz Trucks G550 tire sizes?
The three tire sizes for a 2022 Mercedes-Benz Trucks G550 are not simply style choices; they correspond to different rim diameters. A truck on 18-inch wheels needs 265/60R18, a truck on 19-inch wheels needs 275/55R19, and a truck on 20-inch wheels needs 275/50R20.
Selection becomes much easier once the wheel diameter is confirmed. From there, compare the replacement tire’s intended use, sidewall profile, and how closely it matches the setup already on the vehicle. A G550 with changed wheels or suspension should be measured carefully so the replacement tire works with the actual wheel package and available clearance.
What does 275/50R20 mean on a 2022 Mercedes-Benz Trucks G550?
On a 2022 Mercedes-Benz Trucks G550, 275/50R20 means the tire is 275 millimeters wide, has a 50-series aspect ratio, uses radial construction, and fits a 20-inch rim. It is a modern metric radial size, not an older alphanumeric or numeric bias-ply designation.
Understanding that code helps avoid one of the most common fitment mistakes: matching section width while overlooking rim diameter. The 20 at the end is what ties the tire to a 20-inch wheel. Even on a G550 where other fitments are similar in height, the wheel diameter must still match exactly before moving on to any clearance or appearance considerations.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Mercedes-Benz Trucks G550 restoration?
Correct tire fitment still matters on a 2022 Mercedes-Benz Trucks G550, even though it is a modern vehicle rather than a vintage restoration project. Using the proper size for the wheel diameter preserves the truck’s intended stance, keeps proportions consistent, and avoids the mismatched look that comes from forcing the wrong tire format onto the wrong wheel.
Appearance and fitment are closely linked on a G550 because the body shape makes wheel-and-tire balance highly visible. Anyone aiming for a clean, original-style presentation should confirm whether the truck is on 18-inch, 19-inch, or 20-inch wheels and stay close to that setup. Modified vehicles deserve extra attention so visual changes do not create practical clearance problems.
How does tire construction affect the appearance of a restored 2022 Mercedes-Benz Trucks G550?
On a 2022 Mercedes-Benz Trucks G550, tire construction is straightforward because the primary fitments are radial sizes: 265/60R18, 275/55R19, and 275/50R20. The visual difference is less about bias-ply versus radial and more about the sidewall profile and wheel diameter that each metric radial size creates.
An 18-inch setup leaves more visible sidewall, while a 20-inch setup places more emphasis on the wheel itself. That changes the truck’s presentation even when overall tire height remains close. Anyone refining the look of a G550 should compare the current wheel package carefully and avoid changing tire profile casually without considering stance, proportions, and available space.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Mercedes-Benz Trucks G550?
Yes, modifications can affect tire fitment on a 2022 Mercedes-Benz Trucks G550. Wheel changes, offset differences, suspension lifts or lowering, and body alterations can all change how a 265/60R18, 275/55R19, or 275/50R20 tire sits in the wheel opening and how much room it has during steering and suspension movement.
A G550 that looks stock may still have nonstandard wheels, so measuring the actual setup is worthwhile before replacement. Check wheel diameter first, then confirm width and surrounding clearance at full steering lock. That extra step helps prevent a new tire from creating rubbing issues that were not part of the original wheel-and-tire package.
What should I inspect before driving a 2022 Mercedes-Benz Trucks G550 on new tires?
Before driving a 2022 Mercedes-Benz Trucks G550 on new tires, inspect the wheel diameter match, bead seating, air pressure, valve stems, and visible clearance around the tire. It is also smart to look at the suspension and steering components so the new tires are working with a sound chassis rather than masking another issue.
A short, careful road test is the practical next step. Listen for rubbing, feel for vibration, and recheck pressure after the first drive. Since the G550 can use three different rim diameters, confirming that the installed tire truly matches the wheel and has adequate room through the full steering range is especially important.
How often should tires on a 2022 Mercedes-Benz Trucks G550 be inspected?
Tires on a 2022 Mercedes-Benz Trucks G550 should be inspected regularly, with a quick visual check before driving and a more thorough inspection at routine service intervals. Look for uneven wear, cuts, punctures, sidewall damage, air loss, and any signs that the tire is contacting suspension or bodywork.
That habit is especially useful on a vehicle with multiple possible wheel-and-tire combinations, since previous wheel changes can alter clearance in ways that are easy to miss at a glance. A G550 that sits for periods between drives also deserves pressure checks and age-related inspection, because low-use vehicles can still develop condition problems long before the tread looks worn out.
