2025 Buick Trucks Tire Fitment Guide

2025 Buick Trucks vehicles use seven tire sizes across four models: 275/45R22 and 255/55R20 for Enclave, 245/45R19 and 225/55R18 for Encore GX, 245/45R20 and 235/60R18 for Envision, and 245/45R19, 225/60R17, and 225/55R18 for Envista. The shared sizes are 245/45R19 between Encore GX and Envista, and 225/55R18 between Encore GX and Envista. Rim diameters span 17, 18, 19, 20, and 22 inches depending on model and wheel package.

That spread means year and make alone are not enough to choose a tire for 2025 Buick Trucks. The practical first check is the exact model, then the wheel diameter already on the vehicle, and then the sidewall size molded on the current tire. If the vehicle has been fitted with non-original wheels, confirm the actual installed size before moving on to brand or tread-pattern comparisons.

On a 2025 Buick Trucks tire, 275/45R22 is a metric radial size code. The 275 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 22 is the wheel diameter in inches. Within the 2025 Buick Trucks range, this size belongs to the Enclave and pairs a wide tread section with a large-diameter wheel.

For an Enclave owner, the main value of decoding 275/45R22 is avoiding confusion with the model’s alternate 255/55R20 package. Those two sizes do not interchange casually, because the wheel diameter changes from 20 to 22 inches. Before choosing a replacement, compare the sidewall marking on the current tire to the vehicle’s wheel package so the new tire matches the hardware already on the vehicle.

No, 2025 Buick Trucks models do not all use the same tire size. Enclave uses either 275/45R22 or 255/55R20, Encore GX uses 245/45R19 or 225/55R18, Envision uses 245/45R20 or 235/60R18, and Envista uses 245/45R19, 225/55R18, or 225/60R17. Only two sizes are shared between models, and both of those are shared only by Encore GX and Envista.

That matters because a Buick crossover owner cannot safely assume that another 2025 Buick Trucks model uses the same wheel diameter or sidewall profile. Even when two models share a size, another trim or wheel package within the same showroom family may not. Matching the tire to the actual wheel on the vehicle is the right approach, especially on late-model crossovers where wheel-package changes are common.

Sidewall styles for 2025 Buick Trucks are mainly blackwall, with a narrow whitewall option also appearing in 225/60R17. The 245/45R19 and 245/45R20 fitments are available as blackwall radials from BFGoodrich and Nitto, while the 225/60R17 fitment for Envista is available as a Travelstar radial with a 9-millimeter narrow whitewall. That means appearance changes with size, not just with brand.

For most 2025 Buick Trucks owners, blackwall remains the expected modern look and the easiest way to stay visually in step with current crossover styling. The narrow whitewall on 225/60R17 creates a more distinctive custom appearance and is most relevant to an Envista owner keeping that exact 17-inch fitment. Choosing between them comes down to the look you want on the vehicle, after the size has been confirmed.

Three brands currently cover the 2025 Buick Trucks sizes with available products here: BFGoodrich, Nitto, and Travelstar. BFGoodrich and Nitto cover the 245/45R19 and 245/45R20 radial fitments, while Travelstar covers 225/60R17. Within those sizes, BFGoodrich appears in multiple g-Force series, Nitto appears in the NT555 G2 line, and Travelstar appears in the UN106 line.

Brand choice matters most after the exact tire size is settled, because not every brand appears in every 2025 Buick Trucks fitment. A buyer with 19-inch or 20-inch applications has broader performance-oriented brand selection, while the 17-inch Envista size shown here centers on a single narrow-whitewall option. Comparing brands within the correct size is the sensible path, rather than starting from brand preference alone.

For 2025 Buick Trucks 245/45R20 tires, both BFGoodrich and Nitto offer blackwall radial choices, but their published details are not identical. BFGoodrich options include W- and Y-rated versions, with load figures reaching 1,929 to 1,930 pounds at 50 psi on products where that specification is stated, and they show a 7.5- to 9-inch rim width range. The Nitto NT555 G2 in this size is W-rated and weighs 30.38 pounds.

That makes the comparison less about basic fitment and more about the specific balance of published load information, speed rating, and series preference within the same 20-inch Envision application. Owners who want to compare more closely should review the exact product-side sidewall marking and match it to how the vehicle is used. Staying inside the 245/45R20 size remains the non-negotiable first step.

Published rim-width guidance appears for several 2025 Buick Trucks sizes. The 245/45R19 size fits 7.5- to 9-inch rims on BFGoodrich examples, the 245/45R20 size also fits 7.5- to 9-inch rims on BFGoodrich examples, and the 225/60R17 Travelstar application uses a 6.5J rim. Rim diameter must still match the tire exactly at 19, 20, or 17 inches respectively.

Rim width matters because the same diameter wheel can still be too narrow or too wide for a given tire profile. Before replacing tires on 2025 Buick Trucks, confirm both the wheel diameter and the wheel width stamped on the rim or verify it through a trusted wheel reference. That is especially helpful if the vehicle has aftermarket wheels or if the original wheel package has been changed since new.

The available 2025 Buick Trucks fitments shown here are modern radial applications, and one 245/45R20 BFGoodrich product explicitly carries a tubeless marking. No tube-type marking appears in the available 245/45R19, 245/45R20, or 225/60R17 products shown here. That points these late-model Buick crossover sizes toward modern tubeless service rather than traditional tube-type construction.

Even so, the right installation practice is to inspect the wheel itself before mounting a new tire. A damaged bead seat, corrosion, or a problem valve stem can create issues even when the tire is meant for tubeless use. On 2025 Buick Trucks, a fresh valve-stem inspection and proper wheel condition check are usually more relevant than tube selection when setting up a replacement tire.

A 2025 Buick Trucks vehicle stores best on clean, properly inflated tires kept away from direct sunlight, standing moisture, and electric-motor or ozone-producing equipment. Even though these are radial tires rather than older bias-ply constructions, long static periods still encourage flat spotting, pressure loss, and cosmetic sidewall aging. A cool, dry garage is far better than outdoor storage or a damp carport.

If the vehicle sits for weeks at a time, move it periodically so the tires do not rest on the same contact patch continuously. For longer seasonal storage, many owners also use tire cradles or relieve some weight from the tires with stands placed correctly under the chassis. The goal is to reduce stress, sunlight exposure, and slow air loss while keeping the tire shape as stable as possible.

Tire age on a 2025 Buick Trucks vehicle matters more than raw mileage once the vehicle becomes a low-use or second-car crossover. A sound rule is to begin close inspection around five to seven years of age and to treat the ten-year mark as a serious replacement point, even if tread remains. The DOT date code on the tire sidewall is the best way to verify actual age.

That approach protects owners from relying on tread depth alone, which can be misleading on vehicles that spend more time parked than driven. Rubber hardens with time, and aging can affect wet-weather behavior, ride quality, and resistance to cracking. A 2025 Buick Trucks owner who drives infrequently should still track age carefully and not assume low mileage automatically means long remaining service life.

Tires on a 2025 Buick Trucks vehicle should be checked before every drive and again before any longer highway outing. Look for sidewall cracking, punctures, bulges, irregular tread wear, and pressure loss, and make sure the valve stems are in good condition. On modern radial crossover tires, uneven shoulder wear or repeated low-pressure warnings can also signal alignment or suspension issues.

A quick visual check takes only a minute and often catches problems before they become a roadside interruption. It is also wise to inspect the spare, if equipped, because many drivers focus on the four road tires and forget the backup. For owners who cover limited annual mileage, calendar-based inspection discipline is often more useful than waiting for a mileage interval to come due.

2025 Buick Trucks tires in the available 19-, 20-, and 17-inch fitments carry modern radial construction and highway-capable speed ratings. The 225/60R17 Travelstar is T-rated to 118 mph, the 245/45R19 and 245/45R20 performance-oriented products include W-rated options to 168 mph, and some BFGoodrich products in those sizes are Y-rated to 186+ mph. Those ceilings exceed normal U.S. highway use by a wide margin when the tire is correctly installed, inflated, and in sound condition.

Real-world road safety in a 2025 Buick Trucks crossover depends just as much on inflation pressure, alignment, brake condition, and suspension health as it does on the tire’s speed symbol. The best practice is to treat the speed rating as capacity information, not a target. If the vehicle is loaded for travel or sees sustained interstate use, recheck tire pressures cold and inspect each tire before departure.

Inflation pressure on 2025 Buick Trucks should follow the vehicle placard or owner’s manual for normal service, while the tire’s own maximum-pressure marking shows the upper limit tied to a stated load, not the everyday target for every application. Among the available products here, the 225/60R17 Travelstar carries 1,709 pounds at 44 psi, and BFGoodrich 245/45R19 and 245/45R20 examples reach 1,874 pounds at 50 psi and about 1,929 to 1,930 pounds at 50 psi.

Those figures should not be transferred from one 2025 Buick Trucks size to another, because each size and product can have different load and pressure characteristics. Use the factory placard as the baseline for ride, wear, and handling balance, then make sure the tire itself is appropriate for that application. If the vehicle has non-original wheels or a different replacement tire type, a knowledgeable installer can help confirm the correct cold inflation approach.

Before a longer drive in a 2025 Buick Trucks vehicle, inspect each tire for cuts, punctures, bulges, sidewall damage, and uneven wear, then verify cold inflation pressure and valve-stem condition. Make sure the tire size on the vehicle matches the wheel package actually installed, especially on models such as Enclave, Encore GX, Envision, and Envista that can wear more than one factory-style size. Check the spare as well if the vehicle has one.

Tire preparation is only one part of a sensible pre-trip check on a modern crossover. It is also wise to review brake feel, fluid levels, battery condition, and any active warning lights before heading out. Starting with the tires is worthwhile because they reveal a lot about the vehicle’s readiness, from alignment issues to slow leaks, and they are the only part of the vehicle that touches the road.
