The 2025 Buick Trucks Encore GX sits in the modern compact crossover space, where everyday drivability, refined road manners, and trim-level presentation all shape the tire decision as much as simple size matching. On this exact model, tire fitment centers on two radial sizes, 225/55R18 and 245/45R19, with the correct choice depending on sub-model and wheel setup. That makes this page less about vintage-style construction choices and more about confirming trim, rim diameter, and the kind of tire character you want from the available blackwall performance-oriented options. For an Encore GX that is driven regularly, selecting the right size starts with the exact sub-model and the wheels currently on the vehicle.
Which Tire Size Is Right for The 2025 Buick Trucks Encore GX
The 2025 Buick Trucks Encore GX uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. Both are radial fitments, but one uses an 18-inch rim and the other uses a 19-inch rim, so the first step is confirming the exact sub-model and verifying which wheels are on the vehicle before choosing a tire.
245/45R19 is a metric radial size in which 245 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2025 Buick Trucks Encore GX, this size belongs on a 19-inch wheel and is used on specific sub-model configurations rather than every version. Available choices in this size include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, Nitto NT555 G2, and g-Force Phenom T/A. It is the size to evaluate when the vehicle already wears 19-inch wheels and a sportier low-profile fitment is part of the package.
225/55R18 is a metric radial size where 225 represents nominal section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2025 Buick Trucks Encore GX, this size is tied to 18-inch wheel applications and appears on different sub-model configurations than the 19-inch fitment. Its role in the lineup is to match the vehicle's 18-inch wheel setup rather than serve as an interchangeable alternative to the 19-inch size. Choosing it starts with confirming that the Encore GX has the correct 18-inch rims and the sub-model fitment that uses this size.
Tire fitment for the 2025 Buick Trucks Encore GX varies by sub-model, and one trim can use either of the two primary sizes depending on wheel setup. Checking the exact trim name matters here because the correct tire begins with confirming whether the vehicle uses 18-inch or 19-inch wheels.

2025 Buick Trucks Encore GX Avenir
The 2025 Buick Trucks Encore GX Avenir uses the 245/45R19 radial size. Tire selection for this trim starts with its 19-inch wheel fitment, then moves to comparing available blackwall tire options by brand, series, and wheel-width compatibility.
The 2025 Buick Trucks Encore GX Preferred uses the 225/55R18 radial size. That keeps the focus on matching the vehicle's 18-inch wheel setup first, then selecting a tire that suits the way the Encore GX is actually driven.
The 2025 Buick Trucks Encore GX Sport Touring can use either 225/55R18 or 245/45R19, depending on the wheel package on the vehicle. Tire choice here begins with confirming actual wheel diameter rather than assuming one size applies to every Sport Touring configuration.
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.

Tire Size & Fitment
What tire size fits a 2025 Buick Trucks Encore GX?
The 2025 Buick Trucks Encore GX uses two primary tire sizes: 225/55R18 and 245/45R19. Both are radial fitments, but they do not apply universally across every trim, so the correct size depends on the exact sub-model and wheel package on the vehicle.
The practical first step is confirming whether the Encore GX has 18-inch or 19-inch wheels. Avenir uses 245/45R19, Preferred uses 225/55R18, and Sport Touring can use either size, so checking the actual wheel setup matters before comparing tire options.
What size rim does a 2025 Buick Trucks Encore GX use?
A 2025 Buick Trucks Encore GX uses either an 18-inch or 19-inch rim, depending on the trim and tire size. The 225/55R18 fitment uses an 18-inch wheel, while the 245/45R19 fitment uses a 19-inch wheel.
That rim diameter difference is the key reason tire selection starts with the wheels already on the vehicle. Tire sizes are built around a specific wheel diameter, so an 18-inch tire cannot be used on a 19-inch rim, and a 19-inch tire cannot be used on an 18-inch rim.
Do all 2025 Buick Trucks Encore GX sub-models use the same tire size?
No. The 2025 Buick Trucks Encore GX uses more than one tire size across its sub-models. Avenir uses 245/45R19, Preferred uses 225/55R18, and Sport Touring can use either 225/55R18 or 245/45R19 depending on the wheel configuration.
That means trim name alone is not always enough, especially on a Sport Touring model. It is smart to confirm both the sub-model and the actual wheel diameter on the vehicle before choosing tires, particularly if wheels have been changed since the vehicle was new.
Choosing the Right Tire
What should I consider when choosing a 245/45R19 tire for a 2025 Buick Trucks Encore GX?
Start with correct size, radial construction, and wheel compatibility. For the 2025 Buick Trucks Encore GX, available 245/45R19 choices include blackwall tires from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, Nitto NT555 G2, and g-Force Phenom T/A.
From there, compare details that affect selection, including rim-width specification, load figure where stated, and the general character suggested by the tire series. The right choice depends on whether the vehicle remains on its original 19-inch wheel setup and how the Encore GX is used in regular driving.
What sidewall styles are available for 2025 Buick Trucks Encore GX tires?
The available 245/45R19 tires for the 2025 Buick Trucks Encore GX use a blackwall sidewall style. That keeps the visual presentation modern and straightforward, which suits the current crossover format of the Encore GX rather than a restoration-oriented appearance choice.
Sidewall style matters mostly when the buyer wants a certain look, but it should still come after confirming the correct size and wheel diameter. Once fitment is settled, blackwall becomes part of the overall product comparison along with brand, tire series, and wheel-width compatibility.
What brands offer tires for the 2025 Buick Trucks Encore GX?
For the 245/45R19 fitment used on certain 2025 Buick Trucks Encore GX configurations, available brands include BFGoodrich and Nitto. BFGoodrich appears in more than one tire series, while Nitto is represented by the NT555 G2 in this size.
Brand should be compared alongside the rest of the specification rather than treated as the only decision point. Once the exact size is confirmed, it helps to look at tire series, sidewall style, rim-width range, and any stated load information to narrow the right match.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Buick Trucks Encore GX?
Yes. Wheel changes, suspension alterations, or previous tire substitutions can affect fitment on a 2025 Buick Trucks Encore GX even when the vehicle started with either 225/55R18 or 245/45R19. The most important variables are wheel diameter, width, and the space available around the tire.
A modified Encore GX should be checked carefully before new tires are selected. Confirm the actual wheel size on the vehicle, then look at clearance around the fenders and suspension and make sure the chosen tire matches the intended rim rather than relying only on trim-level assumptions.
What should I inspect before driving a 2025 Buick Trucks Encore GX on new tires?
Before regular road use, inspect the wheels for correct diameter and condition, verify inflation pressure, and check that each tire has proper clearance at full steering lock. It is also worth looking over the suspension and alignment condition so the new tires start life on a sound chassis setup.
A quick follow-up inspection after the first miles is a good habit. Recheck pressure, confirm there is no rubbing, and watch for uneven wear patterns that could point to alignment or wheel issues rather than a problem with the tire itself.
What should I check before a longer drive in a 2025 Buick Trucks Encore GX?
Before a longer trip, make sure the 2025 Buick Trucks Encore GX is on the correct tire size for its wheels, then check inflation pressure, tread condition, and the sidewalls for cuts, bulges, or signs of impact damage. A quick visual look at wheel condition is worthwhile as well.
Longer drives put more heat and load into the tires than local errands, so basic condition checks matter. It also helps to confirm there has been no slow air loss and that the vehicle tracks normally, since vibration or pull can point to alignment, balance, or tire-condition issues.
