The 2022 Mercedes-Benz Trucks GLB250 brings modern Mercedes compact-crossover packaging into a vehicle that still places a strong emphasis on road manners, everyday versatility, and upscale presentation. For owners, tire choice is less about vintage-style construction and more about matching the exact wheel setup already on the vehicle. The 2022 Mercedes-Benz Trucks GLB250 uses radial tires in three fitments: 235/55R18, 235/50R19, and 235/45R20. Those sizes keep a very similar overall diameter while changing sidewall height to suit 18-, 19-, or 20-inch wheels. The key step is confirming the actual rim diameter before selecting a replacement tire for appearance, ride character, and daily road use.
Which Tire Size Is Right for The 2022 Mercedes-Benz Trucks GLB250
Three tire sizes apply to the 2022 Mercedes-Benz Trucks GLB250, and the first step is confirming which wheel diameter is on the vehicle. All three fitments are radial and are used across the covered GLB250 sub-models, but they correspond to different 18-, 19-, and 20-inch wheel setups. Once the wheel size is confirmed, the decision becomes choosing the right replacement within that exact size and profile.
235/45R20 is a metric radial size in which 235 identifies the nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter in inches. On the 2022 Mercedes-Benz Trucks GLB250, this size pairs the largest rim diameter with the shortest sidewall of the three primary fitments. Its overall diameter remains close to the other GLB250 sizes, so the main distinction is the 20-inch wheel requirement rather than a dramatic change in tire height. This is the size to evaluate when the vehicle already has 20-inch wheels and a lower-profile replacement is needed.
235/50R19 is a metric radial size with a 235-millimeter nominal section width, a 50-series profile, radial construction, and a 19-inch rim diameter. For the 2022 Mercedes-Benz Trucks GLB250, it sits between the 18-inch and 20-inch fitments in sidewall height while maintaining a very similar overall diameter. That makes it a straightforward fitment to understand, but it still depends on having the correct 19-inch wheel on the vehicle. This size is the one to select when the GLB250 is equipped with 19-inch rims and the goal is to stay with the original wheel-based fitment path.
235/55R18 is a metric radial size where 235 is the nominal width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2022 Mercedes-Benz Trucks GLB250, this fitment uses the smallest rim diameter and the tallest sidewall among the three primary sizes, while staying close in overall diameter to the 19-inch and 20-inch alternatives. That means wheel diameter remains the deciding factor rather than tire height alone. This size should be considered when the vehicle is running 18-inch wheels and a like-for-like replacement is the priority.
Tire fitment is straightforward across the covered 2022 Mercedes-Benz Trucks GLB250 sub-models because both use the same three size options. The important step is not choosing between trims, but confirming whether the vehicle has 18-, 19-, or 20-inch wheels before ordering replacement tires.

2022 Mercedes-Benz Trucks GLB250 4Matic
The 2022 Mercedes-Benz Trucks GLB250 4Matic uses the same three radial tire fitments found across this model range. Tire selection starts with confirming whether the vehicle is on 18-, 19-, or 20-inch wheels, then choosing a replacement that matches that exact setup.
The 2022 Mercedes-Benz Trucks GLB250 Base shares the same three radial tire sizes as the 4Matic version. That keeps fitment simple at the sub-model level, but the actual wheel diameter still needs to be checked before selecting the correct replacement 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.
Frequently Asked Questions
Common GLB250 tire questions usually center on which of the three sizes belongs on the vehicle, how the 18-, 19-, and 20-inch fitments differ, and what to inspect before replacing tires on a modern Mercedes crossover.
Tire Size & Fitment
What tire size fits a 2022 Mercedes-Benz Trucks GLB250?
The 2022 Mercedes-Benz Trucks GLB250 uses one of three radial tire sizes: 235/55R18, 235/50R19, or 235/45R20. Those sizes correspond to different wheel diameters, and both the Base and 4Matic sub-models can use the same set of fitments depending on how the vehicle is equipped.
The practical step is checking the wheels already on the vehicle rather than choosing by sub-model name alone. A GLB250 with 18-inch rims needs 235/55R18, a 19-inch setup needs 235/50R19, and a 20-inch setup needs 235/45R20. The tire placard, current tire sidewall, and wheel measurement should all agree before replacement.
What size rim does a 2022 Mercedes-Benz Trucks GLB250 use?
A 2022 Mercedes-Benz Trucks GLB250 can use 18-inch, 19-inch, or 20-inch rims, depending on the tire size installed. The matching tire fitments are 235/55R18 for 18-inch wheels, 235/50R19 for 19-inch wheels, and 235/45R20 for 20-inch wheels.
Rim diameter is the most important fitment checkpoint on this vehicle because the three tire sizes are tied directly to three different wheel sizes. Looking only at tread width can be misleading since all three sizes share the same 235-millimeter nominal width. Confirm the actual wheel diameter before comparing tires, especially if the GLB250 has had wheel upgrades or replacement rims.
Do all 2022 Mercedes-Benz Trucks GLB250 sub-models use the same tire size?
The covered 2022 Mercedes-Benz Trucks GLB250 sub-models share the same three tire-size possibilities: 235/55R18, 235/50R19, and 235/45R20. That means the Base and 4Matic versions follow the same overall fitment pattern rather than having separate size families by sub-model.
Even so, that does not mean every GLB250 uses all three sizes at once. The correct replacement still depends on which wheel package is actually on the vehicle. Checking the existing tire sidewall, measuring the wheel diameter, and confirming that all four corners match are worthwhile steps before purchase, particularly on vehicles that may have had previous tire or wheel changes.
Choosing the Right Tire
What should I consider when choosing a 2022 Mercedes-Benz Trucks GLB250 tire?
Start with the exact size already fitted to the vehicle: 235/55R18, 235/50R19, or 235/45R20. On the 2022 Mercedes-Benz Trucks GLB250, the main decision is tied to wheel diameter because all three fitments use the same nominal width but different sidewall profiles and rims.
After size is confirmed, think about how the GLB250 is used. Daily driving, highway travel, ride preferences, and seasonal conditions all matter when comparing replacement tires within the correct size. It also helps to inspect the current wheels for damage, confirm that all four tires match, and make sure no previous owner changed the wheel package from the original setup.
How do I choose between the available 235/55R18, 235/50R19, and 235/45R20 tires for a 2022 Mercedes-Benz Trucks GLB250?
These three sizes are not alternatives to mix casually; each belongs to a different wheel diameter on the 2022 Mercedes-Benz Trucks GLB250. The real choice is selecting the replacement tire that matches the existing 18-inch, 19-inch, or 20-inch wheel setup already on the vehicle.
Once the correct size is identified, compare tires within that size for the kind of use the GLB250 sees most often. An owner may weigh ride comfort, seasonal traction needs, and overall driving feel differently from appearance alone. Staying with the exact size on the sidewall is the safest starting point unless the vehicle is being professionally reconfigured with different wheels.
Should I pick tire size based on sub-model or wheel size for a 2022 Mercedes-Benz Trucks GLB250?
Wheel size is the deciding factor on the 2022 Mercedes-Benz Trucks GLB250. Both the Base and 4Matic versions use the same three tire-size possibilities, so the sub-model name does not narrow the fitment nearly as much as confirming whether the vehicle has 18-, 19-, or 20-inch wheels.
That distinction matters because the tire sizes share a common 235-millimeter width, which can make them look similar at a glance. Reading the full tire code on the current sidewall is the best way to avoid ordering the wrong replacement. It is also smart to verify that the spare, if present, and all four road wheels follow the same intended wheel-and-tire package.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Mercedes-Benz Trucks GLB250 restoration or appearance refresh?
Yes. Even on a modern vehicle like the 2022 Mercedes-Benz Trucks GLB250, correct tire fitment plays a major role in how the vehicle sits, fills the wheel openings, and presents itself overall. The three approved sizes keep a similar overall diameter, but each is designed around a different 18-, 19-, or 20-inch wheel package.
An appearance-focused refresh should still begin with the actual wheel setup on the vehicle. Using the proper size helps preserve the intended proportions between sidewall height and rim diameter, while mismatched sizing can make the GLB250 look off even before clearance or handling issues enter the picture. Matching all four tires is especially important for a clean, cohesive presentation.
How does tire profile affect the appearance of a 2022 Mercedes-Benz Trucks GLB250?
The three GLB250 tire sizes all use the same nominal 235-millimeter width, but the profile changes as wheel diameter changes. A 235/55R18 has the tallest sidewall of the group, 235/50R19 sits in the middle, and 235/45R20 has the shortest sidewall paired with the largest rim.
That profile difference changes the visual balance of the vehicle more than the width does. Taller sidewalls generally give the GLB250 a fuller tire presence, while the 20-inch fitment places more emphasis on the wheel itself. For an appearance refresh, keeping the correct relationship between tire size and wheel diameter is more important than chasing a different look through casual substitutions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Mercedes-Benz Trucks GLB250?
Yes. Wheel changes, suspension lowering, spacer use, or other modifications can affect tire fitment on a 2022 Mercedes-Benz Trucks GLB250 even when the tire size looks close to stock. Because this model uses three different wheel diameters, aftermarket changes can quickly alter the relationship between the tire, fender, and steering components.
A modified GLB250 should be checked for wheel diameter, wheel width, offset, and clearance at full lock and full suspension movement before replacement tires are chosen. It also helps to compare the current tire code on all four corners, since previous owners sometimes stagger wheel changes over time. Verifying the exact setup avoids ordering a tire that suits the model but not the vehicle in front of you.
What should I inspect before driving a 2022 Mercedes-Benz Trucks GLB250 on new tires?
Before putting a 2022 Mercedes-Benz Trucks GLB250 into regular road use on new tires, inspect the wheels for damage, confirm proper mounting size, and make sure tire pressures are set correctly. It is also worth checking alignment-related wear items if the previous tires showed uneven tread wear or edge wear.
A short post-installation review is just as useful as the initial inspection. Recheck pressure after the first drives, listen for rubbing during turns, and make sure the vehicle tracks normally at highway speed. Any vibration, pull, or unusual contact noise deserves attention right away, especially on a GLB250 that may have multiple wheel-size options or prior wheel-package changes.
How often should tires on a 2022 Mercedes-Benz Trucks GLB250 be inspected?
Tires on a 2022 Mercedes-Benz Trucks GLB250 should be inspected regularly, not just when tread looks low. A visual check for uneven wear, cuts, punctures, sidewall damage, and air loss is a smart routine on any modern crossover, especially one that may see a mix of city driving, highway use, and seasonal weather.
Monthly pressure checks and periodic full inspections help catch problems before they turn into ride, handling, or safety concerns. It also makes sense to inspect the tires before longer trips and after impacts with potholes or curbs. On a GLB250, keeping all four tires in matching size and similar condition is an important part of maintaining consistent road manners.
