The 2024 Mercedes-Benz Trucks GLB35 AMG blends compact crossover packaging with AMG-tuned performance, so tire choice matters for both stance and road manners. On a vehicle like this, wheel and tire fitment are tied closely to the exact setup, especially when multiple factory-style rim diameters are in play. The 2024 Mercedes-Benz Trucks GLB35 AMG uses radial tire fitments in 235/50R19, 255/40R20, and 255/35R21. That means the main decision is not bias-ply versus radial, but confirming which wheel package is on the vehicle and then choosing a tire that matches the intended balance of appearance, performance character, and everyday use.
Which Tire Size Is Right for The 2024 Mercedes-Benz Trucks GLB35 AMG
Three tire sizes apply to the 2024 Mercedes-Benz Trucks GLB35 AMG, and the first step is confirming which wheel diameter is actually on the vehicle. These fitments are all radial, but they use different rim diameters, so selecting a tire starts with identifying whether the GLB35 AMG is on 19-inch, 20-inch, or 21-inch wheels before comparing product choices within that size.
A 235/50R19 tire uses a 235-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 19-inch rim. On the 2024 Mercedes-Benz Trucks GLB35 AMG, this size represents a modern radial fitment suited to a 19-inch wheel package rather than one of the larger-diameter alternatives. Its metric sizing format is familiar to current buyers and makes it easier to compare like-for-like replacements. This is the size to evaluate if the vehicle is presently equipped with 19-inch wheels and the goal is to stay with that wheel diameter.
A 255/35R21 tire combines a 255-millimeter nominal section width with a lower 35-series profile, radial construction, and a 21-inch rim diameter. For the 2024 Mercedes-Benz Trucks GLB35 AMG, this fitment belongs to the largest wheel diameter used on this model and should be matched carefully to the actual wheel setup on the vehicle. The lower-profile metric format points toward a more modern, performance-oriented tire presentation. This size is the correct path to explore only after verifying that the GLB35 AMG is running 21-inch wheels.
A 255/40R20 tire uses a 255-millimeter nominal section width, a 40-series profile, radial construction, and a 20-inch rim. On the 2024 Mercedes-Benz Trucks GLB35 AMG, this size sits between the 19-inch and 21-inch fitments and is available in at least one BFGoodrich g-Force Phenom T/A Blackwall option. That gives buyers a visible product choice tied to a specific tire series rather than size alone. This is the fitment to review when the vehicle has 20-inch wheels and the goal is to compare actual product specifications within that setup.
The covered sub-model fitment is straightforward, but it still spans three different wheel and tire sizes. Checking the exact wheel package on the 4Matic model matters more than trim identification alone, since tire selection changes with rim diameter.

2024 Mercedes-Benz Trucks GLB35 AMG 4Matic
The 2024 Mercedes-Benz Trucks GLB35 AMG 4Matic uses all three of this model's radial fitments: 235/50R19, 255/40R20, and 255/35R21. That makes wheel confirmation the key step before choosing a replacement tire, since the decision is tied to the installed rim diameter rather than a different sub-model name.
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.
Best 2024 Mercedes-Benz Trucks GLB35 AMG Tires for Sale
Current product coverage centers on the 255/40R20 fitment, where BFGoodrich offers a g-Force Phenom T/A radial in Blackwall form. For buyers comparing product cards, the most useful differences are tire series, sidewall presentation, load specification, and rim-width compatibility within the correct 20-inch setup.
These FAQs focus on the 2024 Mercedes-Benz Trucks GLB35 AMG tire sizes, wheel-diameter fitment, product selection, and the practical checks that matter before road use. The biggest theme on this vehicle is matching the tire to the actual 19-inch, 20-inch, or 21-inch wheel package.
Tire Size & Fitment
What tire size fits a 2024 Mercedes-Benz Trucks GLB35 AMG?
The 2024 Mercedes-Benz Trucks GLB35 AMG uses three radial tire sizes: 235/50R19, 255/40R20, and 255/35R21. Those sizes correspond to three different wheel diameters, so there is not one universal tire size across every wheel setup on this model.
The practical next step is checking the actual wheel diameter on the vehicle before choosing a replacement tire. A GLB35 AMG on 19-inch wheels needs the 19-inch fitment, while 20-inch and 21-inch packages require their matching sizes, and any past wheel changes should be verified before ordering.
What size rim does a 2024 Mercedes-Benz Trucks GLB35 AMG use?
The 2024 Mercedes-Benz Trucks GLB35 AMG uses 19-inch, 20-inch, and 21-inch rim diameters depending on the wheel and tire setup. The matching tire sizes are 235/50R19 for 19-inch wheels, 255/40R20 for 20-inch wheels, and 255/35R21 for 21-inch wheels.
Rim diameter is the first fitment detail to confirm because the tire must match it exactly. After that, it helps to verify the wheel width and overall setup, especially if the vehicle has aftermarket wheels, since the correct tire size on paper still needs to suit the wheel and available clearance.
Why does the 2024 Mercedes-Benz Trucks GLB35 AMG have more than one tire size?
This model has more than one tire size because it is associated with more than one wheel package. The 2024 Mercedes-Benz Trucks GLB35 AMG uses 235/50R19, 255/40R20, and 255/35R21, all in radial construction, with each size tied to a different rim diameter.
That means the buyer decision starts with the wheels already on the vehicle, not with broad model-year fitment alone. Looking at the sidewall of the current tires or measuring the wheel diameter is the quickest way to narrow the choice and avoid selecting a size intended for another GLB35 AMG wheel setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Mercedes-Benz Trucks GLB35 AMG?
Start with the correct tire size for the wheel package on the vehicle: 235/50R19, 255/40R20, or 255/35R21. Because all three fitments are radial, the main decision is matching the installed rim diameter and then comparing the product details that matter within that exact size.
Useful comparison points include tire series, sidewall style, load specification, rim-width compatibility, and how the tire suits the vehicle's intended use. A GLB35 AMG used mainly for daily road driving may call for a different emphasis than one where appearance or a particular performance-oriented tire presentation matters most.
What sidewall styles are available for 2024 Mercedes-Benz Trucks GLB35 AMG tires?
Among the currently covered products for the 2024 Mercedes-Benz Trucks GLB35 AMG, the visible sidewall style is Blackwall. That sidewall treatment appears on the BFGoodrich g-Force Phenom T/A available in the 255/40R20 fitment.
Sidewall style mainly affects appearance, but it can also help narrow the field when several products share the same size. On this vehicle, sidewall choice should still come after confirming the correct wheel diameter, since the right visual treatment does not override the need to match the actual 19-inch, 20-inch, or 21-inch setup.
What brands offer tires for the 2024 Mercedes-Benz Trucks GLB35 AMG?
BFGoodrich is represented in the current product assortment for the 2024 Mercedes-Benz Trucks GLB35 AMG. The available example is a 255/40R20 BFGoodrich g-Force Phenom T/A radial with a Blackwall sidewall treatment.
Brand is only one part of the selection process on a fitment with multiple wheel diameters. It still makes sense to confirm the exact tire size first, then compare how the available brand options line up with the needed rim width, load specification, and the overall driving role of the vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Mercedes-Benz Trucks GLB35 AMG?
Yes. Wheel changes, suspension modifications, lowering, spacer use, or other alterations can affect tire fitment on a 2024 Mercedes-Benz Trucks GLB35 AMG even when the tire size appears close to a stock-style fitment. This matters especially on a vehicle that already uses more than one wheel diameter.
The safest approach is to verify the actual wheel diameter and width on the vehicle, then check clearance at the fenders, struts, and steering range before changing sizes. A modified GLB35 AMG should be evaluated on its present setup rather than by model name alone, since previous changes can shift fitment requirements.
What should I inspect before driving a 2024 Mercedes-Benz Trucks GLB35 AMG on new tires?
Before road use, inspect inflation pressure, bead seating, valve stems, wheel condition, and the tire sidewalls for any shipping or mounting damage. It also helps to confirm that the new tires match the correct size for the vehicle's installed 19-inch, 20-inch, or 21-inch wheels.
A short clearance check is worthwhile before a full drive, especially at full steering lock and over suspension movement. After the first miles, recheck pressure and look for uneven contact, rubbing, or vibration, since those early signs can reveal wheel, balance, or fitment issues that should be addressed promptly.
How often should tires on a 2024 Mercedes-Benz Trucks GLB35 AMG be inspected?
Tires on a 2024 Mercedes-Benz Trucks GLB35 AMG should be inspected regularly, not just when tread looks low. Routine checks for pressure loss, cuts, bulges, uneven wear, and embedded debris help catch problems early, especially on lower-profile fitments such as 255/35R21 and 255/40R20.
Monthly pressure and condition checks are a sensible baseline, with another inspection before longer drives or seasonal changes. Any vibration, pull, or rubbing noise deserves a closer look right away, because those symptoms can point to alignment issues, wheel damage, or a fitment problem that will not correct itself.
