The 2017 Mercedes-Benz Trucks G550 carries the long-running G-Class character into a modern luxury off-road era, blending upright styling, serious four-wheel-drive heritage, and everyday road presence. Buyers looking at this exact model usually already know that wheel and tire choices affect both stance and drivability more than almost any visual detail. For this G550, the primary fitment is a 275/55R19 radial on a 19-inch rim. That keeps the tire decision focused on selecting the right modern metric radial rather than sorting through multiple original-style vintage formats. The key is confirming the actual wheel setup, then choosing a tire that suits the vehicle's road use, appearance, and overall condition.
Which Tire Size Is Right for The 2017 Mercedes-Benz Trucks G550
The 2017 Mercedes-Benz Trucks G550 uses one primary tire size: 275/55R19. It is a radial fitment on a 19-inch rim, and the covered G550 Base sub-model uses that same size. That means the main decision is not which factory size applies, but choosing the right 275/55R19 tire for the vehicle's current wheel setup, intended use, and overall tire condition.
The 275/55R19 size is a modern metric radial format in which 275 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2017 Mercedes-Benz Trucks G550, this is the primary fitment and it matches the vehicle's modern wheel-and-tire layout. Because the format is already contemporary, selection tends to center on tire design, load suitability, and real-world use rather than converting from an older sizing system. It is worth confirming the actual wheel dimensions and any modifications before final tire selection.
Fitment is straightforward for the covered 2017 Mercedes-Benz Trucks G550 sub-models. The G550 Base uses the same primary tire size, so the focus shifts from size differences to confirming the vehicle still has the correct 19-inch wheel setup.

Frequently Asked Questions
Common questions for the 2017 Mercedes-Benz Trucks G550 usually center on the 275/55R19 tire size, 19-inch wheel fitment, choosing the right radial tire, and checking wheel, suspension, and tire condition before regular road use.
Tire Size & Fitment
What tire size fits a 2017 Mercedes-Benz Trucks G550?
The 2017 Mercedes-Benz Trucks G550 uses a 275/55R19 tire size. This is a radial fitment and it is the primary size for the covered model, including the G550 Base.
That makes the first step fairly simple: confirm that the vehicle still has 19-inch wheels and a stock-style wheel-and-tire setup. If the G550 has aftermarket wheels, changed offset, suspension modifications, or non-original tire sizing already on it, those changes should be checked before selecting a replacement 275/55R19 tire.
What size rim does a 2017 Mercedes-Benz Trucks G550 use?
The primary tire fitment for the 2017 Mercedes-Benz Trucks G550 is built around a 19-inch rim. The 275/55R19 size uses that 19-inch wheel diameter as part of the size designation.
Wheel diameter is only one part of fitment, so it is still smart to confirm the actual wheel width and overall setup on the vehicle before replacing tires. A G550 that has been changed from its original wheel package may still use a 19-inch diameter, but width, offset, and clearance can affect which tire is appropriate.
Does the 2017 Mercedes-Benz Trucks G550 Base use the same tire size?
Yes. The 2017 Mercedes-Benz Trucks G550 Base uses the same 275/55R19 radial tire size. There is no separate primary size for that covered sub-model.
That consistency makes replacement simpler, but it does not remove the need to inspect the actual vehicle. Older or modified examples may have different wheels, and even a matching size should be checked against wheel condition, current tire age, and any signs of rubbing, uneven wear, or suspension issues before regular driving.
Choosing the Right Tire
What should I consider when choosing a 275/55R19 tire for a 2017 Mercedes-Benz Trucks G550?
Start with the correct size, which is 275/55R19 for the covered 2017 Mercedes-Benz Trucks G550. Since this is already a modern radial fitment, the main considerations are matching the 19-inch wheel setup, choosing a tire suited to how the vehicle is driven, and making sure overall condition and load needs are taken seriously.
A G550 used mainly on pavement may call for a different tread character than one that sees rougher surfaces or more seasonal use. It also helps to compare the current wheel package, inspect for uneven wear that could point to alignment or suspension issues, and replace old or weathered tires even if tread depth still looks acceptable.
How do I choose between available 275/55R19 tires for a 2017 Mercedes-Benz Trucks G550?
The best way to compare 275/55R19 tires for a 2017 Mercedes-Benz Trucks G550 is to begin with fitment and intended use rather than appearance alone. Tire choice should support the correct 19-inch wheel diameter, the vehicle's weight and driving conditions, and the kind of ride and road manners the owner expects.
A careful comparison usually includes load-related specifications, tread design, construction details, and how the vehicle is actually used. It is also helpful to inspect the current tires for shoulder wear, center wear, or age cracking, since those clues can point to pressure or chassis issues that should be addressed before a new set goes on.
What rim-fitment details should I compare when choosing 2017 Mercedes-Benz Trucks G550 tires?
Rim diameter is the starting point, and the 2017 Mercedes-Benz Trucks G550 uses a 19-inch setup with the 275/55R19 tire size. Beyond diameter, wheel width and the overall wheel package matter because they affect how the tire sits, clears suspension components, and behaves under load.
Checking the actual wheels on the vehicle is especially important if it has been customized at any point. A different offset, a non-stock wheel width, or a suspension change can alter fender and steering clearance even when the tire size itself appears correct, so those details should be verified before replacement.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Mercedes-Benz Trucks G550?
A period-style approach on a 2017 Mercedes-Benz Trucks G550 still begins with the correct primary fitment, which is 275/55R19. Because this model uses a modern metric radial size rather than a vintage bias-ply format, maintaining the proper modern proportions and wheel diameter is usually the closest match to the vehicle's intended visual character.
Appearance should be balanced with practicality, especially on a heavy, road-capable luxury utility vehicle like the G550. Keeping the correct size relationship matters more than chasing an aggressive look, and owners concerned with exact presentation should also compare the tire's tread and sidewall style with period photos or marque-specific reference material.
Does correct tire fitment matter for a 2017 Mercedes-Benz Trucks G550 restoration?
Yes, correct tire fitment matters because tire size has a strong effect on how a 2017 Mercedes-Benz Trucks G550 sits, fills the wheel openings, and drives. Using the proper 275/55R19 size helps preserve the vehicle's intended stance and keeps the wheel-and-tire package in line with the covered fitment.
A restoration-minded owner should still inspect the actual wheels and verify that no previous owner changed the setup. Even on a newer collector vehicle, oversized tires, wheel swaps, or suspension changes can alter the presentation noticeably, so returning to the correct size is often one of the simplest ways to improve both appearance and usability.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Mercedes-Benz Trucks G550?
Yes. Modifications can affect tire fitment on a 2017 Mercedes-Benz Trucks G550 even when the intended size is still 275/55R19. Wheel width, offset changes, suspension lifts or lowering, and body alterations can all influence clearance at the fenders, steering components, and suspension.
That is why replacement should begin with the vehicle as it sits today, not just the original fitment alone. A quick check of lock-to-lock clearance, ride height, and wheel specifications can help prevent rubbing issues, and any signs of uneven wear may point to geometry changes that deserve attention before new tires are installed.
What should I inspect before driving a 2017 Mercedes-Benz Trucks G550 on new tires?
Before regular driving, inspect tire pressure, wheel hardware, valve stems, and the visible condition of the wheels themselves. It is also wise to look for alignment-related wear, damaged suspension parts, and any evidence that the previous tires contacted the inner fender or steering components.
A 2017 Mercedes-Benz Trucks G550 places real demands on its tires, so the surrounding chassis condition matters. New tires cannot correct worn shocks, poor alignment, or bent wheels, and those problems can shorten tire life quickly. A careful road test and recheck after the first miles can help confirm that everything is seated and wearing normally.
How often should tires on a 2017 Mercedes-Benz Trucks G550 be inspected?
Tires on a 2017 Mercedes-Benz Trucks G550 should be inspected regularly, not just when replacement is due. Pressure, tread wear, sidewall condition, and any signs of cuts, bulges, or air loss deserve attention on a consistent schedule, especially if the vehicle sees mixed road conditions or long periods of storage.
Routine inspection helps catch problems before they become expensive or inconvenient. It is smart to look over the tires before longer drives and any time the vehicle's ride, steering feel, or stance seems different. Collector-use vehicles also benefit from checking age and storage effects, since low mileage does not always mean a tire is still roadworthy.
