The 2024 Mercedes-Benz Trucks GLA35 AMG blends compact luxury crossover packaging with AMG performance character, making tire fitment a more configuration-specific decision than a simple one-size answer. On this exact model, the primary tire choices span 235/50R19, 255/40R20, and 255/35R21, all in radial construction. That means the first step is confirming which wheel package is on the vehicle, since rim diameter changes with the tire size. From there, the focus shifts to matching the right modern metric radial size, checking wheel compatibility, and choosing a tire that suits the vehicle's road use, appearance, and any changes from the original wheel and suspension setup.
Which Tire Size Is Right for The 2024 Mercedes-Benz Trucks GLA35 AMG
The 2024 Mercedes-Benz Trucks GLA35 AMG uses three primary tire sizes, and the correct one depends on the wheel package installed on the vehicle. All three are radial metric sizes, but they fit different rim diameters: 19, 20, or 21 inches. Before selecting a tire, confirm the actual wheel diameter on the vehicle, especially if it has been fitted with aftermarket wheels or a different AMG-style package.
235/50R19 is a metric radial size where 235 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2024 Mercedes-Benz Trucks GLA35 AMG, this size represents one of the standard modern radial fitments and is tied to a 19-inch wheel. It is the more moderate sidewall profile among the available sizes, which makes wheel confirmation especially important before purchase. Choose this size only when the vehicle is actually running the 19-inch setup and the rest of the wheel specifications match the tire requirement.
255/35R21 is a metric radial size with a 255-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 21-inch rim diameter. For the 2024 Mercedes-Benz Trucks GLA35 AMG, this is the largest rim-diameter fitment of the three primary sizes and carries a shorter sidewall profile than the 19-inch option. That makes wheel size and clearance verification especially important if the vehicle has seen any wheel, suspension, or alignment changes. This size should be evaluated as a 21-inch package fitment rather than as a general alternative for every GLA35 AMG.
255/40R20 is a modern metric radial in which 255 describes nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 20 is the wheel diameter in inches. On the 2024 Mercedes-Benz Trucks GLA35 AMG, it is one of the primary fitments and uses a 20-inch rim. Available product choice in this size includes the BFGoodrich g-Force Phenom T/A in Blackwall form, giving buyers at least one clearly performance-oriented option. This size is the right path when the vehicle is equipped with 20-inch wheels and the wheel width and overall setup match the tire's requirements.
Fitment is straightforward here because the covered sub-model uses the same three tire-size pathways tied to different wheel diameters. Checking the exact wheel setup still matters, since the tire choice on this GLA35 AMG 4Matic depends on whether it is running 19-inch, 20-inch, or 21-inch wheels.

The 2024 Mercedes-Benz Trucks GLA35 AMG 4Matic uses radial tire fitments across three wheel-diameter configurations rather than one universal size. Tire selection starts with confirming the actual wheel package on the vehicle, then matching that setup to the correct metric radial size and checking compatibility if the wheels or suspension have been changed.
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.

These FAQs focus on the tire sizes used on the 2024 Mercedes-Benz Trucks GLA35 AMG, how wheel diameter affects fitment, and what to check when choosing, inspecting, and driving on the correct radial setup.
Tire Size & Fitment
What tire size fits a 2024 Mercedes-Benz Trucks GLA35 AMG?
The 2024 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 setup rather than serving as a universal fitment for every vehicle configuration.
The most important step is confirming which wheels are actually on the vehicle before choosing tires. A GLA35 AMG running 19-inch wheels needs a different tire than one equipped with 20-inch or 21-inch wheels, and that remains true even when the overall tire diameters are close. If the vehicle has aftermarket wheels, check wheel diameter and width carefully before moving forward.
What size rim does a 2024 Mercedes-Benz Trucks GLA35 AMG use?
The 2024 Mercedes-Benz Trucks GLA35 AMG appears with three rim diameters: 19 inches, 20 inches, and 21 inches. Those diameters correspond to the three primary tire sizes used on this model, so rim size is a core part of identifying the correct fitment.
A tire's final number tells you the rim diameter it is built to fit, so 235/50R19 belongs on a 19-inch rim, 255/40R20 on a 20-inch rim, and 255/35R21 on a 21-inch rim. It is worth checking the wheel itself rather than assuming by appearance alone, especially on a performance crossover where optional wheels and later wheel changes are common.
Why does the 2024 Mercedes-Benz Trucks GLA35 AMG have more than one tire size?
More than one tire size appears on the 2024 Mercedes-Benz Trucks GLA35 AMG because this model can be equipped with different wheel packages. The tire sizes are tied to 19-inch, 20-inch, or 21-inch rims, so the variation comes from wheel diameter rather than from a separate non-AMG model line.
That means the right choice is not about picking the size you prefer visually. It is about matching the tire to the actual wheel package on the vehicle. Even when two sizes have similar overall diameters, the wrong rim diameter will not work. Owners should also account for any past modifications, since wheel swaps can change the fitment path completely.
Choosing the Right Tire
What should I consider when choosing a 255/40R20 tire for a 2024 Mercedes-Benz Trucks GLA35 AMG?
Start with the basics: confirm that the vehicle is actually using the 20-inch wheel setup and that 255/40R20 is the correct fitment for that wheel package. In this size, available selection includes a radial Blackwall BFGoodrich g-Force Phenom T/A with a stated rim-width range of 8.5 to 10 inches and a maximum load capacity of 1819 pounds at 50 psi.
The practical comparison points are wheel-width compatibility, load specification, tire series character, and how the tire suits the way the vehicle is driven. A 20-inch AMG application can be sensitive to wheel changes, so checking wheel width and overall clearance matters just as much as ordering the right nominal size. That helps avoid mismatch between the tire and the vehicle's current setup.
What sidewall styles are available for 2024 Mercedes-Benz Trucks GLA35 AMG tires?
Among the currently visible product options for this vehicle's covered sizes, Blackwall is the sidewall style that appears. It is shown on the available 255/40R20 BFGoodrich g-Force Phenom T/A, giving the GLA35 AMG a straightforward modern performance presentation rather than a decorative sidewall treatment.
Sidewall style matters mainly for appearance, but it should still be secondary to correct fitment. On a current AMG crossover, most buyers will begin with the proper size and wheel compatibility, then decide whether the tire's look suits the vehicle's visual style. If more than one wheel package is in circulation on the vehicle, size confirmation should happen before appearance becomes the deciding factor.
What brands offer tires for the 2024 Mercedes-Benz Trucks GLA35 AMG?
BFGoodrich is represented among the currently available products for the 2024 Mercedes-Benz Trucks GLA35 AMG, specifically in the 255/40R20 fitment. The tire series shown in that size is the g-Force Phenom T/A, a radial Blackwall performance-oriented offering for the 20-inch wheel setup.
Brand choice should be considered alongside the exact size, wheel diameter, and wheel-width requirement rather than as a separate decision. On this vehicle, fitment varies by wheel package, so a brand available in one size does not automatically solve every GLA35 AMG configuration. Confirm the vehicle's current wheel setup first, then compare the available options within that exact size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Mercedes-Benz Trucks GLA35 AMG?
Yes. Modifications can affect tire fitment on a 2024 Mercedes-Benz Trucks GLA35 AMG even when the tire size appears close to a stock configuration. Aftermarket wheels, changes in wheel width or offset, lowered suspension, alignment changes, or body alterations can all influence how a 19-inch, 20-inch, or 21-inch tire package sits on the vehicle.
That is especially important on a model with multiple factory-style wheel diameters. A tire that belongs to one wheel package should not be assumed to work on another without checking the full setup. Owners should verify wheel diameter first, then confirm wheel width, clearance at full steering lock, and any signs of rubbing under load before committing to a replacement tire.
What should I inspect before driving a 2024 Mercedes-Benz Trucks GLA35 AMG on new tires?
Before road use, inspect inflation pressure, bead seating, valve condition, and overall visual condition of each tire. It also makes sense to confirm that all four tires match the intended wheel package and that there is no interference with suspension parts, inner liners, or fender edges once the vehicle is on the ground.
A short check at low speed can reveal vibration, rubbing, or steering issues before a longer drive. Performance-oriented crossovers place real demands on tires, so it is smart to recheck pressure after installation and watch for uneven wear as the first miles accumulate. Any unusual pull, noise, or clearance concern should be addressed before regular road use continues.
How often should tires on a 2024 Mercedes-Benz Trucks GLA35 AMG be inspected?
Tires on a 2024 Mercedes-Benz Trucks GLA35 AMG should be inspected regularly, not just when tread looks low. A routine monthly pressure and condition check is a sensible habit, and the tires should also be looked over before longer trips or anytime the vehicle has encountered potholes, curb strikes, or noticeable changes in handling.
Inspection should include tread wear pattern, cuts, bulges, punctures, and sidewall damage, along with any signs that the tire is not sitting correctly on the wheel. Because this model may run low-profile 20-inch or 21-inch combinations, impact damage can be easier to miss at a glance. Staying ahead of small issues helps protect both ride quality and fitment integrity.
