The 2016 Mercedes-Benz Trucks GLC300 sits in the modern luxury crossover era, where ride quality, road manners, and wheel-and-tire presentation all play a visible role in how the vehicle feels and looks. On this exact model, tire fitment centers on radial construction, but the real question is not whether it uses radial tires; it is which of the three factory-size paths matches the wheel package on the vehicle now. The GLC300 uses 235/60R18, 235/55R19, or 255/45R20, each tied to a different rim diameter. That makes wheel confirmation the first step, followed by comparing available sidewall styles, brands, and tire character within the correct size.
Which Tire Size Is Right for The 2016 Mercedes-Benz Trucks GLC300
The 2016 Mercedes-Benz Trucks GLC300 uses three primary tire sizes, and the correct choice depends first on wheel diameter. This model appears with 18-inch, 19-inch, or 20-inch rims, all using radial construction, so the first step is confirming the wheel package actually on the vehicle. Once that is settled, the decision shifts to selecting the right tire within that size based on fitment, appearance, and product style.
235/55R19 is a metric radial size in which 235 identifies the section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 19 is the rim diameter in inches. For the 2016 Mercedes-Benz Trucks GLC300, this size represents one of the core factory wheel-and-tire combinations and should be matched to a 19-inch wheel. Its overall proportions keep it close in diameter to the other GLC300 sizes, but that does not make it interchangeable without checking the actual wheel setup. This is the right size to evaluate when the vehicle is equipped with 19-inch rims.
235/60R18 follows the same modern metric radial format, with a 235-millimeter section width, a 60-series profile, radial construction, and an 18-inch rim diameter. On the 2016 Mercedes-Benz Trucks GLC300, it serves as one of the original fitment paths and belongs on an 18-inch wheel, not simply any GLC300 wheel. Its section width is similar to 235/55R19, but the profile and rim combination are different enough that wheel confirmation still matters. Buyers considering this size should start by verifying the current wheel diameter before comparing tire choices.
255/45R20 is a metric radial size with a 255-millimeter section width, a 45-series profile, radial construction, and a 20-inch rim diameter. For the 2016 Mercedes-Benz Trucks GLC300, it is the widest of the three primary sizes and the one with the strongest visible product variety, including BFGoodrich, Nitto, and Pro-Trac options in blackwall, raised white letter, and redline styles across several series. That makes this size especially relevant when appearance plays a role alongside fitment. It should be evaluated only for GLC300s already running the correct 20-inch wheel package.
Tire fitment is straightforward across the covered 2016 Mercedes-Benz Trucks GLC300 sub-models because both use the same three primary sizes. The key check is not the trim name, but which 18-inch, 19-inch, or 20-inch wheel package is on the vehicle before choosing a tire.

The 2016 Mercedes-Benz Trucks GLC300 4Matic uses the same three radial tire sizes found across this model range: 235/60R18, 235/55R19, and 255/45R20. Tire selection starts with confirming the installed wheel diameter, then comparing the available tire choices within that exact size.
The 2016 Mercedes-Benz Trucks GLC300 Base follows the same fitment pattern, with 235/60R18, 235/55R19, and 255/45R20 all applying depending on wheel package. That means the practical decision is centered on wheel confirmation first, followed by selecting the appropriate tire style and brand in the matching size.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2016 Mercedes-Benz Trucks GLC300?
The 2016 Mercedes-Benz Trucks GLC300 uses three primary tire sizes: 235/60R18, 235/55R19, and 255/45R20. All three are radial sizes, and each one corresponds to a different wheel diameter rather than a separate bias-ply or radial decision.
The practical step is to confirm whether the vehicle has 18-inch, 19-inch, or 20-inch wheels before choosing a tire. Even though these sizes are close in overall diameter, the wrong rim diameter will stop installation immediately, and aftermarket wheel changes can affect which size is appropriate now.
What size rim does a 2016 Mercedes-Benz Trucks GLC300 use?
A 2016 Mercedes-Benz Trucks GLC300 can use 18-inch, 19-inch, or 20-inch rims, depending on the wheel-and-tire package on the vehicle. Those rim diameters align with the three primary tire sizes: 235/60R18, 235/55R19, and 255/45R20.
Rim diameter should be verified before anything else because tire size selection starts there. Checking the sidewall marking helps, but physically confirming the wheel size is smart on vehicles that may have had wheel swaps, seasonal wheel sets, or appearance upgrades after they left the showroom.
Do all 2016 Mercedes-Benz Trucks GLC300 sub-models use the same tire size?
The 2016 Mercedes-Benz Trucks GLC300 Base and GLC300 4Matic share the same three tire-size options: 235/60R18, 235/55R19, and 255/45R20. Fitment does not split into a separate size list by those two sub-model names.
That does not mean every GLC300 on the road uses the same tire size at the same time. The deciding factor remains the wheel package actually installed, so the sub-model name helps less here than confirming whether the vehicle is sitting on 18-inch, 19-inch, or 20-inch wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Mercedes-Benz Trucks GLC300?
Start with the correct primary size for the wheel package on the vehicle: 235/60R18, 235/55R19, or 255/45R20. After that, compare construction details that matter for your use, including the specific tire series, sidewall treatment, rim-width compatibility where stated, and any load information supplied with the product.
A GLC300 used mainly for normal road driving may call for a different tire character than one built around a stronger visual statement. Matching the tire to the vehicle’s current wheels, intended use, and preferred appearance will usually matter more than choosing by brand name alone.
What sidewall styles are available for 2016 Mercedes-Benz Trucks GLC300 tires?
Among the available 255/45R20 products for the 2016 Mercedes-Benz Trucks GLC300, sidewall styles include blackwall, raised white letter, and redline. Those treatments can change the visual character of the vehicle even when the size remains the same.
Sidewall choice is mainly an appearance decision, but it still needs to stay within the correct size and wheel fitment. A blackwall keeps the look understated, while raised white letter or redline adds more visual emphasis, especially on vehicles with larger-diameter wheel packages.
What brands offer tires for the 2016 Mercedes-Benz Trucks GLC300?
Current product choices for the 2016 Mercedes-Benz Trucks GLC300 in 255/45R20 include BFGoodrich, Nitto, and Pro-Trac. Those options span several radial tire series rather than a single product pattern or sidewall presentation.
Brand is only one part of the decision. It helps to compare the exact tire series, sidewall style, rim-width specification where given, and any load details shown with the product so the final choice matches both the vehicle setup and the kind of look you want.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mercedes-Benz Trucks GLC300?
Yes. A 2016 Mercedes-Benz Trucks GLC300 may have the correct original tire size range of 235/60R18, 235/55R19, or 255/45R20, but aftermarket wheels, suspension changes, spacers, or altered ride height can change how well a given tire package works on the vehicle.
Wheel diameter is the first check, but width and clearance still matter once modifications enter the picture. It is wise to inspect steering clearance, inner-fender space, and suspension travel before replacing tires, especially when the vehicle no longer carries its original wheel-and-suspension setup.
What should I inspect before driving a 2016 Mercedes-Benz Trucks GLC300 on new tires?
Before road use, inspect the wheel diameter and tire size match, confirm proper inflation, and look over the vehicle for any rubbing concerns around the fenders, suspension, and steering components. Lug hardware, valve stems, and overall wheel condition also deserve attention.
A short test drive followed by a second visual check can catch issues early. Watching for vibration, pull, unexpected contact marks, or pressure loss helps confirm that the chosen tire size suits the actual wheel package and that the vehicle is ready for regular road use.
How often should tires on a 2016 Mercedes-Benz Trucks GLC300 be inspected?
Tires on a 2016 Mercedes-Benz Trucks GLC300 should be inspected regularly, not just at replacement time. Pressure, tread wear, cuts, punctures, sidewall damage, and any visible bulges should be checked routinely, especially before longer drives or seasonal travel.
Vehicles that see mixed use or sit for stretches between drives still benefit from frequent inspection because underinflation and age-related issues can develop quietly. Looking over the tires once a month and before road trips is a sensible routine, particularly if the wheel or tire setup has been changed.
