The 2018 Mercedes-Benz Trucks GLA250 blends compact luxury crossover packaging with the road manners expected from a modern Mercedes-Benz platform. Buyers looking at this exact model are usually balancing everyday drivability with keeping the vehicle’s stance, wheel fitment, and overall look in line with its original character. The GLA250 uses radial tires in two primary sizes, 235/50R18 and 235/45R19, so the first decision is confirming which wheel diameter is on the vehicle. From there, the available choices branch into blackwall performance-oriented radials and select redline or raised white letter styles in 18-inch fitment. Wheel size, appearance goals, and any aftermarket changes should all be checked before choosing.
Which Tire Size Is Right for The 2018 Mercedes-Benz Trucks GLA250
The 2018 Mercedes-Benz Trucks GLA250 uses two primary tire sizes, and both are radial fitments. The key difference is wheel diameter: 235/50R18 fits 18-inch wheels, while 235/45R19 fits 19-inch wheels. Since both the Base and 4Matic versions can use either size, the first thing to confirm is the actual wheel package currently on the vehicle before comparing tire style, series, or sidewall treatment.
A 235/45R19 size uses a 235-millimeter section width, a 45-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2018 Mercedes-Benz Trucks GLA250, this size represents the larger-wheel fitment and should be matched to an actual 19-inch wheel before anything else is considered. Its lower-profile metric radial format is familiar to modern buyers and aligns with contemporary crossover tire sizing. This size is the right starting point for a GLA250 already equipped with 19-inch wheels, especially when keeping the existing wheel diameter is part of the plan.
A 235/50R18 size also uses a 235-millimeter section width and radial construction, but with a taller 50-series profile on an 18-inch rim. For the 2018 Mercedes-Benz Trucks GLA250, this size offers the broadest visible product variety, including BFGoodrich, Nitto, and Pro-Trac options with blackwall, redline, and raised white letter sidewalls across several tire series. That makes it a useful fitment for buyers who want more choice in appearance and product character. It is the correct size to evaluate only when the vehicle is running 18-inch wheels.
Tire fitment is straightforward across the covered 2018 Mercedes-Benz Trucks GLA250 sub-models because both the Base and 4Matic versions use the same two primary radial sizes. The important detail is not the trim name so much as confirming whether the vehicle has 18-inch or 19-inch wheels.

2018 Mercedes-Benz Trucks GLA250 4Matic
The 2018 Mercedes-Benz Trucks GLA250 4Matic uses the same two radial tire sizes found elsewhere in the model line, so wheel diameter remains the deciding factor. Tire selection comes down to verifying whether the vehicle is on 18-inch or 19-inch wheels and then choosing the right style and series for that setup.
The 2018 Mercedes-Benz Trucks GLA250 Base shares the same overall fitment pattern, with both 18-inch and 19-inch radial tire sizes in use. That means a Base model owner should confirm the actual wheel package on the vehicle first, then compare available tire choices within the correct 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.

These FAQs focus on the exact tire sizes used on the 2018 Mercedes-Benz Trucks GLA250, how 18-inch and 19-inch wheel fitments differ, and what to compare when choosing tires for road use, appearance, and overall compatibility.
Tire Size & Fitment
What tire size fits a 2018 Mercedes-Benz Trucks GLA250?
The 2018 Mercedes-Benz Trucks GLA250 uses two primary radial tire sizes: 235/50R18 and 235/45R19. Both the Base and 4Matic sub-models can use either size, so the fitment difference is tied to the wheel package rather than to a separate tire size reserved for one trim.
The practical step is to confirm the wheel diameter currently on the vehicle before choosing a tire. An 18-inch wheel takes the 235/50R18 size, while a 19-inch wheel takes the 235/45R19 size. If the GLA250 has been fitted with aftermarket wheels, checking the wheel markings and current tire sidewall is the safest place to start.
What size rim does a 2018 Mercedes-Benz Trucks GLA250 use?
A 2018 Mercedes-Benz Trucks GLA250 uses either an 18-inch or 19-inch rim, depending on which tire size is on the vehicle. The 235/50R18 tire is matched to an 18-inch rim, and the 235/45R19 tire is matched to a 19-inch rim.
That makes wheel confirmation more important than trim name when replacing tires on this model. Looking at the sidewall of the current tire or the stamping on the wheel will usually answer the question quickly. A buyer should not assume a Base or 4Matic model automatically uses one rim diameter or the other without checking the actual vehicle.
Do all 2018 Mercedes-Benz Trucks GLA250 sub-models use the same tire size?
The 2018 Mercedes-Benz Trucks GLA250 Base and 2018 Mercedes-Benz Trucks GLA250 4Matic share the same overall fitment pattern. Both sub-models use the same two radial tire sizes, 235/50R18 and 235/45R19, so there is no separate size split between those two covered versions.
That means the real fitment question is which wheel package is on the vehicle now. Once the wheel diameter is confirmed, tire selection becomes much simpler because you can compare products within the correct size instead of trying to decode trim-level differences. Any wheel swap, appearance package change, or aftermarket setup should be treated as a reason to verify before purchasing.
Choosing the Right Tire
What should I consider when choosing a 235/50R18 tire for a 2018 Mercedes-Benz Trucks GLA250?
Start with the basics: the tire must be the correct 235/50R18 size for an 18-inch-wheel GLA250, and it should match the kind of driving and appearance you want. Within this size, available options differ by brand, tire series, sidewall style, rim-width specification, weight, and in some cases published load information.
A buyer comparing 235/50R18 tires should look at more than the size alone. BFGoodrich, Nitto, and Pro-Trac options bring different visual presentations and product personalities, including blackwall, redline, and raised white letter styles. Checking the wheel width on the vehicle is also worthwhile, since several 18-inch products include rim-width guidance that helps narrow the right choice.
What sidewall styles are available for 2018 Mercedes-Benz Trucks GLA250 tires?
For the 2018 Mercedes-Benz Trucks GLA250 in 235/50R18, available sidewall styles include blackwall, redline, and RWL, which stands for raised white letter. That gives the 18-inch fitment a wider appearance range than many modern crossover tire selections, especially for buyers who want something more distinctive than a plain black sidewall.
Sidewall treatment does not change the need to stay with the correct size and wheel diameter, but it can change the vehicle’s visual character significantly. A blackwall tends to keep a cleaner contemporary look, while redline or raised white letter options add more visual emphasis. Appearance should be balanced with the tire series, wheel setup, and how the GLA250 is actually used.
What brands offer tires for the 2018 Mercedes-Benz Trucks GLA250?
Available 235/50R18 tires for the 2018 Mercedes-Benz Trucks GLA250 come from BFGoodrich, Nitto, and Pro-Trac. Those brands appear across several 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 choice matters less than making sure the tire matches the correct wheel diameter, size, and intended character of the vehicle. Some buyers will focus on a straightforward blackwall radial, while others may want a redline or raised white letter presentation. Comparing rim-width guidance, sidewall style, and series details will usually be more useful than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Mercedes-Benz Trucks GLA250?
A period-style choice for a 2018 Mercedes-Benz Trucks GLA250 still begins with the correct modern radial size for the wheel on the vehicle: 235/50R18 or 235/45R19. Among the visible options, the 18-inch fitment offers the most appearance variety, including blackwall, redline, and raised white letter styles that can shift the vehicle’s look noticeably.
The right direction depends on what kind of presentation you want the GLA250 to have. A blackwall keeps the look closer to a standard modern crossover appearance, while redline or raised white letters create a more custom visual effect. If exact as-delivered appearance matters, checking original vehicle literature or marque-specific references is a smart extra step.
How does tire construction affect the appearance of a restored 2018 Mercedes-Benz Trucks GLA250?
On the 2018 Mercedes-Benz Trucks GLA250, the primary fitments are radial tires, so construction does not create a bias-ply versus radial appearance decision the way it would on an older collector vehicle. The visual difference here comes more from wheel diameter, sidewall profile, and sidewall treatment than from a change in basic tire construction.
That makes the 18-inch versus 19-inch setup especially important to the finished look. A 235/50R18 and a 235/45R19 both belong to the vehicle, but they present differently because of the wheel and profile combination. Within the 18-inch size, blackwall, redline, and raised white letter options offer additional ways to shape the appearance without departing from radial construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Mercedes-Benz Trucks GLA250?
Yes, modifications can affect tire fitment on a 2018 Mercedes-Benz Trucks GLA250 even when the tire size looks close to stock. Wheel swaps, offset changes, suspension lowering, and body modifications can all alter clearance around the fenders, struts, and steering range, which matters on both the 235/50R18 and 235/45R19 fitments.
A modified GLA250 should be checked as an individual vehicle rather than assumed to match an unmodified setup. Confirm the actual wheel diameter and width, then look at clearance with the steering turned and the suspension loaded. Uneven tire wear can also point to alignment or suspension issues that need attention before a fresh set of tires goes into service.
What should I inspect before driving a 2018 Mercedes-Benz Trucks GLA250 on new tires?
Before driving a 2018 Mercedes-Benz Trucks GLA250 on new tires, inspect the wheels for the correct diameter, look for any visible damage, and confirm the tires match the intended size for the vehicle’s setup. It is also worth checking valve stems, lug torque, and basic suspension condition so the new tires are not being asked to compensate for another problem.
After installation, watch for rubbing, vibration, pull, or unusual noise during the first miles. Tire pressure should be set correctly and monitored closely as the tires seat in. A quick recheck of clearance at full steering lock is especially helpful if the vehicle has aftermarket wheels or if the GLA250 has recently been changed from one wheel package to another.
How often should tires on a 2018 Mercedes-Benz Trucks GLA250 be inspected?
Tires on a 2018 Mercedes-Benz Trucks GLA250 should be inspected regularly, not just when replacement time comes around. A simple visual check for cracking, cuts, punctures, bulges, irregular wear, and pressure loss can catch problems early, whether the vehicle is driven daily or spends long periods parked between uses.
Monthly checks are a sensible habit, and an extra inspection before a longer trip is even better. Vehicles that sit can develop age-related issues that are easy to miss until road speed and heat bring them out. Looking at tread wear across the full width of the tire can also reveal alignment or inflation issues before they shorten the life of the replacement set.
