The 2022 Mercedes-Benz Trucks GLA35 AMG blends compact crossover packaging with AMG tuning, giving it a modern performance character that depends heavily on the right tire and wheel combination. On this exact model, tire fitment centers on three radial sizes: 235/50R19, 255/40R20, and 255/35R21, all tied to different wheel diameters rather than old-style bias-ply sizing questions. That makes wheel confirmation the first step before comparing tire options. For owners focused on road manners, appearance, or replacing a worn set after a wheel change, the real task is matching the correct size to the actual 19-, 20-, or 21-inch setup already on the vehicle.
Which Tire Size Is Right for The 2022 Mercedes-Benz Trucks GLA35 AMG
The 2022 Mercedes-Benz Trucks GLA35 AMG uses three primary tire sizes, and the first thing to confirm is the wheel diameter on the vehicle. All three are radial metric sizes, but they correspond to different 19-, 20-, and 21-inch wheel setups, so selecting the right tire starts with identifying the actual wheel package on the GLA35 AMG 4Matic.
235/50R19 is a modern metric radial size in which 235 is the section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2022 Mercedes-Benz Trucks GLA35 AMG, this size belongs to a 19-inch wheel setup and reflects a contemporary low-profile performance-oriented fitment rather than a vintage sizing system. It should be chosen only when the vehicle is already equipped with the corresponding 19-inch wheels. Checking the wheel itself before replacement is more important here than comparing by appearance alone.
255/35R21 is a metric radial size with a 255-millimeter section width, a 35-series profile, and a 21-inch rim diameter. For the 2022 Mercedes-Benz Trucks GLA35 AMG, it represents the most aggressive wheel-diameter fitment of the three primary sizes and belongs to a distinct 21-inch wheel package. The lower profile makes size accuracy especially important because there is less visual sidewall to mask a mismatch. This size should be evaluated by confirming the actual wheel diameter and making sure the replacement matches the existing setup rather than another GLA35 AMG wheel option.
255/40R20 is a metric radial size that uses a 255-millimeter section width, a 40-series aspect ratio, and a 20-inch rim diameter. On the 2022 Mercedes-Benz Trucks GLA35 AMG, this size fits a 20-inch wheel package and is available in BFGoodrich's g-Force Phenom T/A series with a Blackwall sidewall treatment. That gives buyers at least one clearly performance-oriented product choice in this exact size. It is the right path only for vehicles already running 20-inch wheels, and the wheel width should also be checked against the tire's stated compatibility range before replacement.
Fitment is straightforward here because the covered sub-model uses the same three primary tire sizes tied to different wheel packages. The important check is not trim hierarchy, but which wheel diameter is actually on the vehicle before selecting a replacement tire.

Tire Size & Fitment
What tire size fits a 2022 Mercedes-Benz Trucks GLA35 AMG?
The 2022 Mercedes-Benz Trucks GLA35 AMG uses three primary tire sizes: 235/50R19, 255/40R20, and 255/35R21. All three are radial metric sizes, and each one corresponds to a different wheel diameter rather than a universal fitment shared across one rim size.
The key step is matching the tire to the wheels actually installed on the vehicle. A GLA35 AMG 4Matic may have 19-, 20-, or 21-inch wheels, so checking the sidewall of the current tire or the wheel itself is the safest way to avoid ordering the right width and profile on the wrong rim diameter.
What size rim does a 2022 Mercedes-Benz Trucks GLA35 AMG use?
A 2022 Mercedes-Benz Trucks GLA35 AMG can use 19-inch, 20-inch, or 21-inch rims depending on the tire size fitted to the vehicle. The matching tire sizes are 235/50R19 for 19-inch rims, 255/40R20 for 20-inch rims, and 255/35R21 for 21-inch rims.
That means rim diameter has to be confirmed before any tire comparison begins. Sidewall markings make this easy to verify, and the wheel itself should also be checked if the vehicle has had a previous wheel swap, aftermarket package, or seasonal setup change that may not match the original delivery configuration.
Does the 2022 Mercedes-Benz Trucks GLA35 AMG 4Matic use the same tire size?
The 2022 Mercedes-Benz Trucks GLA35 AMG 4Matic is associated with all three primary tire sizes used on this model: 235/50R19, 255/40R20, and 255/35R21. That does not mean all three sizes fit the same wheel at once; it means the sub-model appears with different wheel and tire packages.
For replacement purposes, the practical question is which wheel package is on the vehicle today. A 4Matic wearing 20-inch wheels needs a 20-inch tire, not simply any size used somewhere on the same sub-model, so checking the mounted tire and wheel diameter prevents a costly mismatch.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Mercedes-Benz Trucks GLA35 AMG?
Start with the exact tire size already fitted to the vehicle: 235/50R19, 255/40R20, or 255/35R21. On a modern AMG-tuned crossover, that size match matters because width, profile, and rim diameter work together as a package rather than as loosely interchangeable dimensions.
After size is confirmed, compare construction, load specification, sidewall style, and any wheel-width guidance tied to the tire. Driving use also matters, since a road-focused daily driver, a carefully kept low-mile example, and a vehicle with aftermarket wheels may each call for a different balance of appearance, response, and fitment caution.
What sidewall styles are available for 2022 Mercedes-Benz Trucks GLA35 AMG tires?
Among the currently available options for this fitment, the visible sidewall style is Blackwall. The 255/40R20 BFGoodrich g-Force Phenom T/A uses that presentation, which suits the modern performance character of the 2022 Mercedes-Benz Trucks GLA35 AMG without introducing a vintage-style sidewall treatment.
Sidewall style does not change the need to match the correct tire size and wheel diameter, but it can affect the overall look of the vehicle. Buyers replacing only two tires or trying to maintain a consistent appearance across a full set should compare sidewall presentation just as carefully as size, load specification, and wheel compatibility.
What brands offer tires for the 2022 Mercedes-Benz Trucks GLA35 AMG?
Current product availability for this exact fitment includes BFGoodrich in the 255/40R20 size. That option appears in the g-Force Phenom T/A series, giving owners of the 20-inch wheel setup a clearly defined brand and series combination to evaluate.
Brand should be considered alongside the exact size on the vehicle, not as a shortcut to fitment. A strong brand option in one wheel package does not make it appropriate for the 19-inch or 21-inch setups, so confirming the mounted tire size remains the first step before comparing product details or replacing part of a set.
Restoration & Appearance
Which tire should I choose for a period-style 2022 Mercedes-Benz Trucks GLA35 AMG?
A 2022 Mercedes-Benz Trucks GLA35 AMG sits firmly in the modern performance era, so a period-style choice usually means staying true to its contemporary wheel-and-tire presentation rather than chasing vintage styling cues. That starts by keeping the correct metric radial size already matched to the vehicle's 19-, 20-, or 21-inch wheel package.
Appearance still matters, especially on a well-kept enthusiast vehicle, but the cleaner route is to preserve the intended stance and profile of the existing setup. Matching the original wheel diameter, maintaining an appropriate sidewall shape, and avoiding improvised size substitutions will usually do more for the vehicle's look than changing to an unrelated style.
Does correct tire fitment matter for a 2022 Mercedes-Benz Trucks GLA35 AMG restoration or preservation project?
Yes, correct tire fitment matters even on a modern collector or preservation-minded 2022 Mercedes-Benz Trucks GLA35 AMG. The visual balance of the vehicle depends on the right relationship between wheel diameter, tire width, and sidewall profile, and this model's three primary sizes create noticeably different presentations.
Preservation work benefits from consistency as much as mechanical correctness. Keeping the proper 19-, 20-, or 21-inch fitment helps maintain the vehicle's intended stance and avoids the awkward look that can come from a mismatched profile, especially when replacing a damaged tire after a previous owner changed wheels or mixed sizes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Mercedes-Benz Trucks GLA35 AMG?
Yes, modifications can affect tire fitment on a 2022 Mercedes-Benz Trucks GLA35 AMG. Wheel changes, altered offset, suspension lowering, spacer use, or body modifications can all influence whether the original 235/50R19, 255/40R20, or 255/35R21 sizing still clears properly under steering and suspension movement.
A vehicle that has been changed from stock should be measured rather than assumed. Confirm wheel diameter first, then check width, clearance at full lock, and any signs of rubbing around the inner fender or suspension before choosing replacement tires, especially when trying to match a setup installed by a previous owner.
What should I inspect before driving a 2022 Mercedes-Benz Trucks GLA35 AMG on new tires?
Before driving, inspect tire pressure, tread seating, valve stems, and the overall condition of the wheels. It also makes sense to verify that all four tires match the intended wheel diameters and that the installed size is the correct one for the specific 19-, 20-, or 21-inch package on the vehicle.
A short visual check can prevent larger problems once the vehicle is moving. Look for sidewall damage, uneven gap to suspension parts, fresh rub marks, or any sign that a wheel was bent or incorrectly mounted, and pay close attention after the first few miles for vibration, air loss, or steering pull.
How often should tires on a 2022 Mercedes-Benz Trucks GLA35 AMG be inspected?
Tires on a 2022 Mercedes-Benz Trucks GLA35 AMG should be inspected regularly, not just when tread looks low. A quick check every month and a closer inspection before longer trips helps catch air loss, irregular wear, cuts, sidewall damage, or impact issues that can matter on low-profile performance-oriented tire sizes.
Inspection becomes even more important when the vehicle is driven infrequently or parked for long periods. Modern performance tires can age, lose pressure, or develop damage that is easy to miss at a glance, so checking condition, pressure, and wear pattern routinely is a smart habit even on a clean, low-mile example.
