Mercedes-Benz Trucks GL350 Tires
Mercedes-Benz Trucks GL350 models from 2010 through 2016 sit in the modern luxury SUV era, where ride quality, all-weather capability, and wheel package choices all play a direct role in tire selection. The GL350 combined full-size utility with diesel-powered touring manners, so tire fitment is tied as much to factory wheel diameter and equipment package as it is to the model year itself. Tire choice is not completely straightforward here because the Mercedes-Benz Trucks GL350 used more than one size during its production run, and one year carries three different fitment paths. Start by confirming the wheel diameter on the actual Mercedes-Benz Trucks GL350 before narrowing the correct tire size.
Mercedes-Benz Trucks GL350 Tire Size Guide
Mercedes-Benz Trucks GL350 production used 3 distinct tire sizes from 2010 through 2016. Wheel diameter varied during the run, with 20-inch, 18-inch, and 19-inch fitments appearing across different years and configurations, and the first additional wheel diameter appears in 2013. All three sizes use modern metric radial sizing, so the section width, aspect ratio, radial construction, and wheel diameter are all built into the size code itself.
275/50R20 is the longest-running Mercedes-Benz Trucks GL350 tire size and appears throughout 2010 through 2016. The code indicates a 275 millimeter section width, a 50-series aspect ratio, radial construction, and a 20-inch rim diameter. Choose this size for Mercedes-Benz Trucks GL350 models equipped with 20-inch wheels, especially when verifying a vehicle that remained on the same wheel package across the full production span.
265/60R18 applies only to the 2013 Mercedes-Benz Trucks GL350. The code indicates a 265 millimeter section width, a 60-series aspect ratio, radial construction, and an 18-inch rim diameter. Choose this size only for a 2013 Mercedes-Benz Trucks GL350 fitted with 18-inch wheels, since that year includes multiple fitment paths and wheel diameter is the key first check.
275/55R19 fits Mercedes-Benz Trucks GL350 models from 2013 through 2016. The code indicates a 275 millimeter section width, a 55-series aspect ratio, radial construction, and a 19-inch rim diameter. Choose this size for Mercedes-Benz Trucks GL350 vehicles carrying 19-inch wheels, and verify the actual wheel package because it overlaps in years with both 18-inch and 20-inch fitments.
Mercedes-Benz Trucks GL350 buyers with a 2013 model must identify the specific configuration before selecting a tire, because that year includes a rim-diameter split across 18-inch, 19-inch, and 20-inch wheels.
Mercedes-Benz Trucks GL350 Tires by Year
The year listing breaks Mercedes-Benz Trucks GL350 tire sizes out by production year so you can narrow fitment before comparing individual products. Mercedes-Benz Trucks GL350 production expanded beyond 20-inch wheels in 2013, adding 18-inch and 19-inch fitments, so confirm which rim diameter the specific vehicle carries before selecting a tire. In 2013, more than two sizes are listed, which points to a wheel-package split rather than a single across-the-board fitment.

Frequently Asked Questions
The FAQ below focuses on the Mercedes-Benz Trucks GL350 sizing questions that matter most, especially the three-way 2013 wheel split and the overlap between 18-inch, 19-inch, and 20-inch fitments across later years.
Size Basics & Fitment
Mercedes-Benz Trucks GL350 models from 2010 through 2016 use three tire sizes: 275/50R20, 265/60R18, and 275/55R19. The 275/50R20 size spans every year from 2010 to 2016, 265/60R18 appears only in 2013, and 275/55R19 is used from 2013 through 2016. Each size is tied to its matching wheel diameter, so the final number in the code corresponds to an 18-inch, 19-inch, or 20-inch rim.
That means year alone is not always enough to identify the right tire for a Mercedes-Benz Trucks GL350. A 2013 model can legitimately use three different sizes, and later years can overlap between 19-inch and 20-inch fitments. Check the tire sidewall already on the vehicle, confirm the wheel diameter directly, and compare both against the year-specific listing before making a final selection.
The 2013 Mercedes-Benz Trucks GL350 is the one year in this range that shows three separate fitments: 265/60R18, 275/55R19, and 275/50R20. That is a wheel-diameter split, not three interchangeable sizes for the same wheel. Each option corresponds to a different rim size, so the tire must match the wheel actually fitted to the vehicle.
A buyer working with a 2013 Mercedes-Benz Trucks GL350 should treat wheel diameter as the first and most important verification step. Once the vehicle is confirmed to have 18-inch, 19-inch, or 20-inch wheels, the correct tire size follows directly. If the vehicle has changed hands or had wheels replaced, verify what is on the truck now rather than assuming the original configuration stayed in place.
Mercedes-Benz Trucks GL350 fitments in this range use 18-inch, 19-inch, and 20-inch wheel diameters. The earliest years, 2010 through 2012, use 20-inch fitment only with 275/50R20. Beginning in 2013, 18-inch and 19-inch alternatives appear alongside the 20-inch fitment, and 19-inch and 20-inch sizes continue through 2016.
Rim diameter matters because a tire sized for one wheel cannot be mounted correctly on another. The last number in each metric size code gives you that wheel diameter directly, so 265/60R18 fits an 18-inch rim, 275/55R19 fits a 19-inch rim, and 275/50R20 fits a 20-inch rim. Confirm the wheel on the Mercedes-Benz Trucks GL350 itself before comparing tread patterns or brands.
Buying the Right Tire
A 2014 Mercedes-Benz Trucks GL350 uses either 275/50R20 or 275/55R19. The correct choice depends on the wheel diameter fitted to that specific vehicle, not simply the model year. If the wheel is 20 inches, the matching tire size is 275/50R20; if the wheel is 19 inches, the matching tire size is 275/55R19.
The simplest way to verify a 2014 Mercedes-Benz Trucks GL350 is to read the size stamped on the tire sidewall already installed and confirm that it matches the wheel itself. If the truck has had wheel changes at some point, measure the wheel diameter or verify against the factory wheel package information for that individual vehicle. That extra check prevents choosing the right size for the year but the wrong size for the actual wheel.
Maintenance & Longevity
A stored Mercedes-Benz Trucks GL350 should be kept in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and sources of ozone. Tires last better when they are clean, properly inflated, and not carrying unnecessary static load for long periods. If the vehicle will sit for extended stretches, moving it occasionally or supporting it to reduce flat-spotting can help preserve ride quality.
Because Mercedes-Benz Trucks GL350 models are heavy luxury SUVs, storage practices matter more than they do on very light collector cars. Check inflation before and after storage, keep the truck off damp ground, and avoid letting one section of the tread remain compressed for months at a time. If the vehicle is exercised only seasonally, a brief inspection before each outing should become part of the routine.
Tires on a Mercedes-Benz Trucks GL350 should be given a visual inspection before every meaningful drive and a closer hands-on inspection several times خلال the year. Look for cracking, impact damage, irregular shoulder wear, embedded debris, tread separation signs, and pressure loss. Because this model can use multiple wheel and tire packages, checking that all four tires match the intended size and construction is also important.
Collector-oriented use often means long idle periods followed by occasional highway trips, which can hide age-related issues until the vehicle is back in service. Make inspection part of spring recommissioning, fall storage prep, and any pre-trip checklist. If the Mercedes-Benz Trucks GL350 has recently been acquired, a fresh inspection establishes a baseline and can reveal whether the current tires are appropriate for the wheels now on the truck.
Mercedes-Benz Trucks GL350 tires should be replaced when they show age cracking, sidewall damage, vibration from internal deterioration, repeated air loss, impact breaks, or any signs of tread or belt distress, even if usable tread depth remains. Tread alone does not tell the full story on a low-mileage collector or specialty-use vehicle. Time, storage conditions, and exposure can age a tire long before the tread wears out.
That is especially important on a Mercedes-Benz Trucks GL350 because its weight and road-speed capability place meaningful demand on the tires. A truck that looks lightly used may still be riding on old rubber that no longer performs as intended. If there is any uncertainty about age or condition, have the tires evaluated before regular road use and replace them once structural condition becomes questionable, not after a failure.
Restoration & Authenticity
Mercedes-Benz Trucks GL350 fitments in this year range include 275/50R20, 265/60R18, and 275/55R19, depending on year and wheel package. The earliest 2010 through 2012 trucks use 275/50R20, while 2013 introduces 18-inch and 19-inch alternatives, and 2014 through 2016 continue with 19-inch and 20-inch fitments. That means original tire size is tied to the exact vehicle configuration rather than the GL350 name alone.
For an authenticity-minded Mercedes-Benz Trucks GL350 owner, the right approach is to confirm the original wheel and tire package for the individual truck before selecting replacements. Window-sticker information, factory option records, and marque-specific references are more useful than broad model-year assumptions. Matching the vehicle to its original wheel diameter is the first step, and matching the corresponding tire size follows from there.
Correct tire fitment can affect how a Mercedes-Benz Trucks GL350 presents in a preservation, concours, or collector setting because wheel-and-tire proportion is part of the vehicle's overall appearance and specification. A truck wearing the wrong diameter tire or an incorrect overall profile can look visibly off even when the difference seems small on paper. On later collector vehicles, authenticity often starts with matching the proper wheel package and size code.
That practical effect matters even more on a Mercedes-Benz Trucks GL350 because several legitimate fitments overlap within the production run. A buyer, appraiser, or judge may look for consistency between the year, wheel diameter, and tire size. If presentation and historical correctness matter, verify the intended configuration first, then select the tire size that belongs with that wheel rather than choosing only by cosmetic preference.
Mercedes-Benz Trucks GL350 models from 2010 through 2016 belong to a modern luxury SUV era where contemporary blackwall radial presentation is the expected visual direction. The important authenticity point on this model is less about wide whitewalls or prewar-style sidewall treatment and more about keeping the size, profile, and wheel diameter consistent with the truck's original configuration. The three listed GL350 sizes all reflect that later radial-era approach.
For a restoration or preservation-focused Mercedes-Benz Trucks GL350, start with the correct wheel diameter and matching size before worrying about finer cosmetic details. A 20-inch truck should still look like a 20-inch truck, and the same applies to 18-inch and 19-inch versions. Keeping the sidewall profile appropriate to the original fitment helps the vehicle retain the stance and visual balance Mercedes intended.
Safety & Road Use
A Mercedes-Benz Trucks GL350 can be driven on public roads when it is fitted with the correct size for its wheel diameter and the tires are in sound condition. In this range, that means matching 265/60R18 to 18-inch wheels, 275/55R19 to 19-inch wheels, or 275/50R20 to 20-inch wheels. Proper pressure, even wear, and freedom from age-related damage are just as important as choosing the right size.
Road safety begins with fitment accuracy because a wrong-size tire can affect load support, clearance, and handling. Once sizing is confirmed, inspect for cracking, bulges, puncture history, and any vibration that suggests internal damage. A Mercedes-Benz Trucks GL350 is capable of sustained road use, but that capability depends on the actual condition of the tires fitted today, not simply the fact that the size code is correct.
Before driving a Mercedes-Benz Trucks GL350, check the tire size against the wheel diameter, confirm inflation pressure, inspect the sidewalls and tread, and make sure there is no visible damage or unusual wear. Also verify that all four tires are a consistent fitment set appropriate to the truck. On a model with overlapping 19-inch and 20-inch applications, that basic confirmation avoids preventable mismatch issues.
A useful pre-drive routine for a Mercedes-Benz Trucks GL350 also includes watching for signs of age after storage, such as flat spotting, fine cracking, or a pull that was not present before. If the truck has recently been purchased or returned to service after sitting, give it a short, cautious shakedown run before any longer trip. Small issues usually reveal themselves early if the vehicle is checked methodically.
Appropriate speed for a Mercedes-Benz Trucks GL350 depends on the exact tire fitted, its present condition, and whether it is an age-worn original-spec replacement or a more recently manufactured road-use tire in the correct size. The GL350 is a modern-era full-size SUV, so road use expectations are different from antique vehicles, but tire condition still governs safe operation. Even the correct 18-inch, 19-inch, or 20-inch size should not be treated as permission to ignore age or structural condition.
The practical rule is to drive a Mercedes-Benz Trucks GL350 only at speeds suitable for the condition of the tires actually on the truck. Fresh, properly fitted tires in sound condition support normal use more confidently than aged tires with uncertain service history. If there is any question about age, storage history, or internal condition, keep speeds conservative until the tires have been professionally evaluated.
