The 2022 Mercedes-Benz Trucks GLA250 blends compact luxury crossover packaging with the sharper wheel-and-tire sizing expectations of a modern premium vehicle. Its low-profile radial fitments reflect that balance, giving the GLA250 a contemporary stance while keeping overall tire height closely matched across different wheel packages. This model uses 235/55R18, 235/50R19, and 235/45R20 radial tire sizes, all tied to the exact wheel diameter on the vehicle. The real choice is not vintage-style construction or period appearance, but confirming the wheel setup already on the vehicle and selecting the right radial tire within that size. That matters even more if the GLA250 has had wheel upgrades or other modifications.
Which Tire Size Is Right for The 2022 Mercedes-Benz Trucks GLA250
Three primary tire sizes apply to the 2022 Mercedes-Benz Trucks GLA250, and the difference comes down to wheel diameter rather than a change from bias-ply to radial construction. Both the Base and 4Matic versions use 235/55R18, 235/50R19, or 235/45R20, so the first step is confirming whether the vehicle is on 18-inch, 19-inch, or 20-inch wheels before choosing a tire.
A 235/45R20 size uses a 235-millimeter section width, a 45-series aspect ratio, radial construction, and a 20-inch wheel. On the 2022 Mercedes-Benz Trucks GLA250, this is the lowest-profile of the three primary fitments and belongs on a 20-inch rim only. Its overall dimensions stay very close to the other factory fitment sizes, but the wheel diameter changes the tire choice completely. This size is the one to evaluate when the vehicle already wears 20-inch wheels and you want to keep the same fitment approach.
A 235/50R19 tire keeps the same 235-millimeter section width as the other GLA250 fitments, but uses a 50-series profile on a 19-inch wheel. It is a radial size designed for the wheel package that sits between the 18-inch and 20-inch setups used on this model. Because the tire's overall height remains close to the other approved sizes, the key distinction is wheel diameter rather than a dramatic change in tire proportions. This fitment should be chosen only when the GLA250 is equipped with 19-inch rims.
A 235/55R18 tire combines a 235-millimeter section width with a 55-series aspect ratio and radial construction on an 18-inch wheel. For the 2022 Mercedes-Benz Trucks GLA250, it is the tallest-profile primary fitment in the group, although its overall diameter remains closely aligned with the 19-inch and 20-inch options. That makes it part of the same general sizing strategy, just built around a smaller rim. This is the correct size to consider when the vehicle retains or currently uses 18-inch wheels.
Tire fitment is straightforward across the covered 2022 Mercedes-Benz Trucks GLA250 sub-models because the same three radial sizes appear on both versions. The important check is not trim-specific sizing, but confirming which wheel diameter is actually on the vehicle before selecting a replacement tire.

2022 Mercedes-Benz Trucks GLA250 4Matic
The 2022 Mercedes-Benz Trucks GLA250 4Matic uses the same group of primary radial tire sizes as the other covered GLA250 configuration. Tire selection comes down to matching the vehicle's existing 18-inch, 19-inch, or 20-inch wheel setup and then choosing the right replacement tire within that exact size.
The 2022 Mercedes-Benz Trucks GLA250 Base shares the same primary radial tire-size range as the 4Matic model. That means the practical step is verifying the wheel diameter already fitted to the vehicle, especially if a previous owner changed wheels or tire package 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
These FAQs focus on the exact tire sizes used on the 2022 Mercedes-Benz Trucks GLA250, how wheel diameter affects fitment, and what to check when choosing replacement radial tires for a stock or modified vehicle.
Tire Size & Fitment
What tire size fits a 2022 Mercedes-Benz Trucks GLA250?
The 2022 Mercedes-Benz Trucks GLA250 uses three primary tire sizes: 235/55R18, 235/50R19, and 235/45R20. All three are radial metric sizes, and each one is tied to a specific wheel diameter rather than representing interchangeable primary fitments on the same rim.
Choosing the right one starts with the wheel currently on the vehicle. A GLA250 on 18-inch wheels needs 235/55R18, a 19-inch setup needs 235/50R19, and a 20-inch setup needs 235/45R20. Checking the tire sidewall and measuring wheel diameter is especially worthwhile if the vehicle has been modified or purchased used.
What size rim does a 2022 Mercedes-Benz Trucks GLA250 use?
The 2022 Mercedes-Benz Trucks GLA250 uses three possible rim diameters: 18-inch, 19-inch, and 20-inch. Those wheel diameters correspond directly to the three primary tire sizes used on the vehicle: 235/55R18, 235/50R19, and 235/45R20.
The rim diameter must match the final number in the tire size exactly. A 235/45R20 tire belongs on a 20-inch wheel, while 235/50R19 and 235/55R18 belong on 19-inch and 18-inch wheels respectively. That makes wheel confirmation the first fitment step before comparing tire models, load capability, or other replacement details.
Do all 2022 Mercedes-Benz Trucks GLA250 sub-models use the same tire size?
The covered 2022 Mercedes-Benz Trucks GLA250 sub-models share the same set of tire sizes. Both the GLA250 Base and GLA250 4Matic use 235/55R18, 235/50R19, and 235/45R20 as primary radial fitments depending on the wheel package on the vehicle.
That means the sub-model alone does not narrow the tire choice to one size. The practical check is the actual wheel diameter fitted to the vehicle now. Once that is confirmed, tire selection becomes much simpler, and there is less risk of ordering an 18-inch, 19-inch, or 20-inch tire for the wrong wheel.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Mercedes-Benz Trucks GLA250?
Start with the exact size already on the vehicle: 235/55R18, 235/50R19, or 235/45R20. The 2022 Mercedes-Benz Trucks GLA250 uses radial construction across all three fitments, so the main selection issue is matching the correct wheel diameter and maintaining the intended tire size.
After size confirmation, compare the tire's role in your driving routine, along with wheel compatibility and the condition of the suspension and alignment. A used GLA250 may have different wheels than it left with, so the sidewall marking and actual rim diameter matter more than assumption when choosing the next set.
How do I choose between the available 2022 Mercedes-Benz Trucks GLA250 tire sizes?
The three sizes used on the 2022 Mercedes-Benz Trucks GLA250 are not alternate choices for the same wheel. Each size belongs to a different rim diameter: 235/55R18 for 18-inch wheels, 235/50R19 for 19-inch wheels, and 235/45R20 for 20-inch wheels.
That means the decision is made by the wheel package already on the vehicle, not by personal preference alone. Once the wheel diameter is confirmed, focus on finding a quality radial tire in that exact size. If the vehicle has aftermarket wheels, verify both the wheel markings and the current tire sidewall before replacing anything.
What does 235/45R20 mean on a 2022 Mercedes-Benz Trucks GLA250?
On a 2022 Mercedes-Benz Trucks GLA250, 235/45R20 identifies a metric radial tire with a 235-millimeter section width, a 45-series aspect ratio, and a 20-inch rim diameter. The R indicates radial construction, which is the standard construction type across this model's primary tire fitments.
Understanding that code helps prevent one of the most common replacement mistakes: matching width while missing wheel diameter. A 235-width tire with a different aspect ratio or rim size is not the same fitment. Keeping the full size code intact is the safest way to preserve intended wheel compatibility and overall tire proportions.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Mercedes-Benz Trucks GLA250 restoration or cosmetic refresh?
Yes. Even on a modern luxury crossover like the 2022 Mercedes-Benz Trucks GLA250, correct tire fitment matters for both appearance and function. The three primary sizes keep a similar overall tire height while pairing with different wheel diameters, so the visual balance of the vehicle depends on using the proper size for the wheel.
A cosmetic refresh can be undermined by the wrong aspect ratio or mismatched rim diameter, even if the tire seems close at a glance. Owners aiming for an original-style presentation should verify the wheel package actually fitted to the vehicle and preserve the corresponding 18-inch, 19-inch, or 20-inch tire size.
Which tire size should I keep for a factory-inspired look on a 2022 Mercedes-Benz Trucks GLA250?
A factory-inspired appearance on a 2022 Mercedes-Benz Trucks GLA250 starts with keeping the same tire size that matches the wheel package already on the vehicle. That means 235/55R18 on 18-inch wheels, 235/50R19 on 19-inch wheels, or 235/45R20 on 20-inch wheels.
Each of those sizes preserves the intended relationship between sidewall height and wheel diameter for that setup. Changing to a different primary size without changing wheels is not an option, and changing both wheels and tires can alter the vehicle's stance. Confirming what is on the vehicle now is the best first step for appearance-minded owners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Mercedes-Benz Trucks GLA250?
Yes. Modifications can change tire fitment on a 2022 Mercedes-Benz Trucks GLA250 even when the original primary sizes are known. Aftermarket wheels, different offsets, suspension changes, lowering, or body alterations can all affect how a 235/55R18, 235/50R19, or 235/45R20 tire sits and clears the vehicle.
That makes it important to inspect the actual setup instead of relying only on model-year fitment. Wheel diameter is just the starting point. Owners should also verify clearance at full steering lock, look for rubbing marks, and confirm that the wheel and tire combination currently on the vehicle matches its intended use.
What should I inspect before driving a 2022 Mercedes-Benz Trucks GLA250 on new tires?
Before driving a 2022 Mercedes-Benz Trucks GLA250 on new tires, confirm that the tire size matches the wheel diameter exactly and inspect the wheels for damage or bends. It also makes sense to check alignment condition, valve stems, and whether the new tire clears suspension and body components throughout the steering range.
A careful first inspection helps catch issues that are easy to miss during installation. Pay attention to air pressure, unusual vibration, and any signs of contact after the first miles. On a vehicle with prior wheel or suspension changes, that verification step is especially important before regular commuting or longer highway use.
How often should tires on a 2022 Mercedes-Benz Trucks GLA250 be inspected?
Tires on a 2022 Mercedes-Benz Trucks GLA250 should be inspected regularly, not just when replacement time comes around. Frequent checks for uneven wear, punctures, cuts, bulges, and pressure loss are important on any modern crossover, especially one that may run lower-profile sizes such as 235/45R20.
A quick visual inspection every few weeks and a more thorough check before longer trips is a sensible routine. Tire condition should also be reviewed after pothole impacts or curb contact. Keeping an eye on wear pattern and inflation can reveal alignment or suspension problems before they become a larger fitment issue.
