The 2019 Mercedes-Benz Trucks GLA250 brings compact luxury crossover packaging together with the planted stance and road manners buyers expect from a modern Mercedes-Benz design. It is a contemporary vehicle, but tire choice still matters in a very old-fashioned way: the right size must match the wheel setup already on the vehicle. This GLA250 uses radial tires in two primary sizes, 235/50R18 and 235/45R19, so the first step is confirming whether it wears 18-inch or 19-inch wheels. From there, the decision shifts to sidewall style, tire series, and whether the vehicle is being kept visually understated or given a more performance-oriented look.
Which Tire Size Is Right for The 2019 Mercedes-Benz Trucks GLA250
The 2019 Mercedes-Benz Trucks GLA250 uses two primary tire sizes, and both are radial fitments. The key difference is wheel diameter, since one size fits an 18-inch rim and the other fits a 19-inch rim. Before choosing a tire, confirm which wheel package is on the vehicle, because both the Base and 4Matic versions can use either size.
235/45R19 is a metric radial size in which 235 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2019 Mercedes-Benz Trucks GLA250, this size belongs to the 19-inch wheel setup rather than the 18-inch alternative. Its role is straightforward: it is the correct primary fitment when the vehicle is already equipped with 19-inch wheels. Tire selection in this size should start with wheel confirmation and then move to the product characteristics that best match the vehicle's intended appearance and road use.
235/50R18 is a metric radial size with a 235-millimeter nominal section width, a 50-series profile, radial construction, and an 18-inch rim diameter. For the 2019 Mercedes-Benz Trucks GLA250, this size is used on the 18-inch wheel package and carries the broadest visible product variety. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, Redline, and RWL sidewall treatments across several tire series. This is the size to evaluate when the vehicle already has 18-inch wheels and the buyer wants to compare appearance, brand, and street-oriented tire character.
Tire fitment is straightforward across the covered GLA250 sub-models because both the Base and 4Matic versions use the same two primary sizes. What matters most is not the badge on the vehicle, but whether it is wearing the 18-inch or 19-inch wheel setup.

2019 Mercedes-Benz Trucks GLA250 4Matic
The 2019 Mercedes-Benz Trucks GLA250 4Matic uses the same primary tire-size choices as the rest of the model range, both in radial construction. Tire selection starts by confirming whether the vehicle has 18-inch or 19-inch wheels, then comparing product style and specifications within the correct size.
The 2019 Mercedes-Benz Trucks GLA250 Base also uses the same two primary radial sizes found elsewhere in the lineup. The practical decision is wheel-based rather than trim-based, so verifying the actual wheel diameter on the vehicle should come before choosing among available tire series and sidewall treatments.
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.

Available 235/50R18 tires for the 2019 Mercedes-Benz Trucks GLA250 include BFGoodrich, Nitto, and Pro-Trac options. The main differences are tire series, Blackwall versus Redline or RWL sidewall presentation, and rim-width specifications within this 18-inch radial fitment.
Owners of a 2019 Mercedes-Benz Trucks GLA250 usually need to sort out wheel diameter first, then compare tire size, sidewall style, and product choice. These FAQs focus on 18-inch versus 19-inch fitment, radial selection, appearance, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2019 Mercedes-Benz Trucks GLA250?
The 2019 Mercedes-Benz Trucks GLA250 uses two primary tire sizes: 235/50R18 and 235/45R19. Both are radial fitments, and both the Base and 4Matic sub-models can use either size depending on the wheel package installed on the vehicle.
The important next step is confirming the actual wheel diameter before selecting a tire. A GLA250 with 18-inch wheels needs the 235/50R18 size, while a vehicle with 19-inch wheels needs 235/45R19. Checking the tire sidewall already on the vehicle and verifying wheel size prevents ordering the correct size for the wrong rim.
What size rim does a 2019 Mercedes-Benz Trucks GLA250 use?
A 2019 Mercedes-Benz Trucks GLA250 uses either an 18-inch or 19-inch rim, depending on which primary tire size is on the vehicle. The 235/50R18 fitment uses an 18-inch rim, and the 235/45R19 fitment uses a 19-inch rim.
That wheel-diameter difference is the central fitment issue for this model. The vehicle does not have one universal rim size across every setup, so the wheel itself must be checked before comparing tires. Once the rim diameter is confirmed, the buyer can focus on tire series, sidewall styling, and other product differences within the correct size.
Do all 2019 Mercedes-Benz Trucks GLA250 sub-models use the same tire size?
The Base and 4Matic versions of the 2019 Mercedes-Benz Trucks GLA250 share the same two primary tire sizes, 235/50R18 and 235/45R19. Fitment does not split into different sizes by sub-model alone, since either version can appear with either wheel-and-tire package.
That means the sub-model badge is less important than the wheel setup actually on the vehicle. A buyer should verify whether the GLA250 is wearing 18-inch or 19-inch wheels, especially if it has seen prior wheel changes. Once that is settled, choosing among the available tires becomes much more straightforward.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Mercedes-Benz Trucks GLA250?
Start with the correct primary size for the wheel already on the vehicle, since the 2019 Mercedes-Benz Trucks GLA250 uses either 235/50R18 or 235/45R19. After size is confirmed, compare radial construction details such as tire series, sidewall style, rim-width compatibility, load specification, and the kind of driving the vehicle actually sees.
A GLA250 used mostly for regular street driving may call for a different product emphasis than one being styled for a more aggressive visual effect. It also helps to check whether the vehicle still has its original wheels or has been changed previously. Correct size comes first, but the best match also depends on appearance goals and wheel compatibility.
What sidewall styles are available for 2019 Mercedes-Benz Trucks GLA250 tires?
Within the available 235/50R18 fitment for the 2019 Mercedes-Benz Trucks GLA250, sidewall choices include Blackwall, Redline, and RWL. Blackwall keeps the look more understated, while Redline and raised white letter styling add a stronger visual statement on an otherwise modern radial tire.
Sidewall treatment does not change the need to stay with the correct tire size and wheel diameter. It is mainly an appearance decision once fitment is settled. A buyer trying to keep the GLA250 visually subtle may lean toward Blackwall, while someone looking for a more expressive street look may prefer Redline or RWL.
What brands offer tires for the 2019 Mercedes-Benz Trucks GLA250?
Available 235/50R18 tires for the 2019 Mercedes-Benz Trucks GLA250 come from BFGoodrich, Nitto, and Pro-Trac. Those choices span several radial tire series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand alone should not make the entire decision. It is more useful to compare the correct size, sidewall treatment, rim-width specification, load figures where stated, and the visual character of each series. Once the wheel diameter is confirmed, those details do a better job of narrowing the right tire for the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Mercedes-Benz Trucks GLA250?
A period-style choice for a 2019 Mercedes-Benz Trucks GLA250 still begins with the correct modern radial size for the wheel on the vehicle, either 235/50R18 or 235/45R19. Since this is a late-model vehicle, the appearance decision usually comes down to whether the tire should look subtle and contemporary or more visually assertive.
Blackwall tires suit a clean, restrained presentation, while Redline or RWL options in 235/50R18 create a more customized street look. The goal is to match the tire's appearance to the vehicle's overall character without losing sight of proper wheel diameter and fitment. Exact originality questions are best checked against vehicle-specific references when that level of detail matters.
Which sidewall style suits a period-style 2019 Mercedes-Benz Trucks GLA250?
For a 2019 Mercedes-Benz Trucks GLA250, sidewall style is more about visual direction than historical authenticity. Blackwall gives the most understated presentation, while Redline and RWL on available 235/50R18 tires create a more noticeable custom-performance look that stands out much more strongly at a glance.
The right choice depends on how the vehicle is being presented. A buyer aiming for a cleaner factory-inspired appearance will usually want a quieter sidewall, while a more individualized build may benefit from the extra contrast of Redline or raised white letters. Size and wheel compatibility still come first, because appearance should never override basic fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mercedes-Benz Trucks GLA250?
Yes. On a 2019 Mercedes-Benz Trucks GLA250, wheel changes, altered suspension height, and other modifications can affect which tire size works properly. That matters especially on a model that already uses two different wheel diameters, because an aftermarket setup may no longer match the original 18-inch or 19-inch tire choice.
Wheel width, offset, steering clearance, and fender room should all be checked before changing sizes or replacing tires on a modified vehicle. Even when the sidewall shows one of the standard GLA250 sizes, prior changes can alter how that size behaves on the vehicle. A careful measurement check is worthwhile before committing to a replacement.
What should I inspect before driving a 2019 Mercedes-Benz Trucks GLA250 on new tires?
Before driving a 2019 Mercedes-Benz Trucks GLA250 on new tires, check that the tire size matches the wheel diameter, confirm proper mounting direction where applicable, and make sure inflation is set correctly for the vehicle's requirements. It is also wise to inspect the wheels for damage and verify that the tires seat evenly.
A short follow-up inspection after the first drive can catch issues early. Look for rubbing at full steering lock, unusual vibration, or any sign that the wheel-and-tire package does not sit correctly on the vehicle. Lug torque, air pressure stability, and basic clearance are worth rechecking before normal driving resumes.
How often should tires on a 2019 Mercedes-Benz Trucks GLA250 be inspected?
Tires on a 2019 Mercedes-Benz Trucks GLA250 should be inspected regularly, not only when replacement time arrives. A routine visual check for uneven wear, cuts, bulges, embedded debris, and pressure loss helps catch problems before they become more serious, especially on a vehicle that may switch between seasonal or style-driven wheel setups.
Monthly pressure checks are a sensible habit, and a closer inspection before longer drives adds another margin of confidence. Owners should also pay attention to age-related deterioration if the vehicle is driven infrequently. Even when tread looks acceptable, sidewall condition and stable air retention matter just as much for safe road use.
