2022 Buick Trucks Tire Fitment Guide

2022 Buick Trucks vehicles use six different tire sizes across four models. The Enclave uses 255/55R20 or 255/65R18, the Encore uses 215/55R18, the Encore GX uses 225/55R18, and the Envision uses 245/45R20 or 235/60R18. Rim diameter is either 18 inches or 20 inches, depending on the model and wheel package. A confirmed rim width range appears for 245/45R20 at 7.5 to 9.0 inches.

That means year and make alone are not enough for a confident tire choice on 2022 Buick Trucks. Buyers should first identify the exact model, then verify the wheel diameter on the vehicle, and then match the full size from the tire placard or the current tire. That step matters most on Enclave and Envision, since each can appear with either 18-inch or 20-inch fitments.

On a 2022 Buick Trucks tire, 245/45R20 is a metric radial size. The 245 is the nominal section width in millimeters, 45 is the aspect ratio, R means radial construction, and 20 is the wheel diameter in inches. On this year and make, that size belongs to the Envision rather than the full Buick crossover range.

The practical takeaway is that 245/45R20 is tied to a 20-inch Envision application, not to every 2022 Buick Trucks model. It also has the most visible product coverage here, with Blackwall tires from BFGoodrich and Nitto and speed ratings that vary between W and Y depending on the tire. Matching the exact code is more important than choosing a similar-looking 20-inch size.

No, 2022 Buick Trucks models do not all use the same tire size. The compact Encore and Encore GX each use their own 18-inch fitments, while the larger Enclave and midsize Envision each have two possible sizes tied to different wheel packages. All of them use radial construction, but the actual dimensions differ by model.

That difference affects replacement decisions immediately. An Encore owner should not assume Encore GX fitment is interchangeable, and an Envision or Enclave owner should not assume the vehicle has the larger wheel package without checking. The cleanest path is to confirm the model name, then read the size molded into the sidewall or printed on the door-jamb placard before selecting a tire.

The available 2022 Buick Trucks products shown here use a Blackwall sidewall style in 245/45R20. That fits the contemporary character of late-model Buick crossovers, where a clean black sidewall is the normal visual treatment rather than a vintage whitewall or decorative sidewall design. No alternate sidewall style appears within the currently covered 245/45R20 offerings.

For most 2022 Buick Trucks buyers, sidewall appearance is a secondary decision after confirming the correct model and size. If your Envision uses 245/45R20, the choice within this group is more about brand and speed rating than sidewall presentation. Owners focused on maintaining an original late-model look will generally find Blackwall styling appropriate to the vehicle’s era and market position.

For 2022 Buick Trucks fitments covered here, 245/45R20 is available from BFGoodrich and Nitto. BFGoodrich appears in multiple g-Force variants, while Nitto is represented by the NT555 G2. All of these are radial Blackwall tires aimed at modern road use rather than vintage-style replacement needs.

Brand choice matters most once the size is confirmed, especially on a model like the Envision that can use either an 18-inch or 20-inch setup. A buyer comparing BFGoodrich and Nitto in 245/45R20 should pay attention to speed rating, load information, and the intended driving character of the specific tire line. The brand decision comes after the fitment decision, not before it.

In 245/45R20 for 2022 Buick Trucks, BFGoodrich appears in several versions, including g-Force Sport Comp-2, g-Force Comp 2 A/S, and g-Force Phenom T/A, while Nitto appears as the NT555 G2. The BFGoodrich tires shown here include W- and Y-rated versions, and the Nitto carries a W rating. Confirmed rim width guidance of 7.5 to 9.0 inches appears on the BFGoodrich products in this size, and weight sits around 30 pounds across the examples shown.

That makes the comparison less about raw fitment and more about the character of the specific tire line once you know your Envision uses 245/45R20. A buyer should compare the exact series name, speed rating, and load information before choosing among them. When two tires share the same size code, details within the sidewall marking still matter.

A confirmed rim width range is available for one 2022 Buick Trucks size here: 245/45R20 fits rims from 7.5 to 9.0 inches wide. That size belongs to the Envision 20-inch application. The other Buick sizes in this year group are identified by tire size and wheel diameter, but no rim width range is attached to them in the covered products.

For buyers working with 245/45R20, that 7.5-to-9.0-inch range is an important fitment checkpoint before mounting a replacement tire. If your Buick uses one of the other sizes, the safer path is to verify the original wheel specification from the vehicle placard, owner information, or a marque-experienced service source. Tire size and wheel width should always be treated as a pair.

The 2022 Buick Trucks products covered here are modern radial tires, and the 245/45R20 examples do not indicate a tube-type fitment. One BFGoodrich all-season example includes a TL marking, which denotes tubeless construction. That aligns with what most buyers would expect on late-model Buick crossover wheels.

Tube questions usually matter more on vintage wheels and older tire constructions than they do on 2022 Buick Trucks applications. Even so, it is still smart to inspect the wheel condition, valve stem condition, and the exact sidewall marking on the tire you choose. Tubeless fitment depends on both the tire and the wheel being suitable for tubeless service.

Original 2022 Buick Trucks wheels cannot be assumed to work with all six tire sizes, because the lineup uses both 18-inch and 20-inch fitments and the tire widths differ by model. An Enclave or Envision may use either wheel diameter, while Encore and Encore GX each have their own distinct 18-inch specifications. A 20-inch tire must stay with a 20-inch wheel, and an 18-inch tire must stay with an 18-inch wheel.

That makes wheel verification especially important on used vehicles, vehicles with replacement wheels, or models that were available with multiple factory packages. If the current wheels are original, matching the sidewall size to the placard is usually the fastest check. If the wheels have been changed, confirm both wheel diameter and approved tire width before moving ahead.

A 2022 Buick Trucks vehicle should be stored on a clean, dry surface away from direct sunlight, electric motors, battery chargers, and other ozone-producing equipment that can age rubber. Keeping the tires properly inflated during storage helps the sidewalls hold their shape, and moving the vehicle occasionally prevents long static loading in one spot. Because these are radial applications, they generally tolerate normal collector-style storage better than an old bias-ply setup would.

For seasonal or low-mileage use, the biggest enemies are heat, UV exposure, and neglect rather than simple mileage. If the vehicle will sit for an extended period, check inflation before and after storage and avoid letting one tire stay underinflated for months. Clean storage habits make a noticeable difference in tread life, sidewall condition, and ride quality once the Buick returns to the road.

Tires on a 2022 Buick Trucks vehicle should be judged by age as much as by tread depth. A sound rule for collector or low-use service is to begin paying close attention around five to seven years of age and to treat ten years as a point where replacement deserves serious consideration, even if tread remains. The DOT date code on the sidewall is the best way to determine the tire’s age.

That approach matters because many premium and specialty vehicles cover relatively few miles, so a tire can look usable while still aging out. Heat cycles, sun exposure, storage conditions, and inflation habits often matter more than odometer readings. If a 2022 Buick Trucks vehicle spends long periods parked, age-related inspection should become part of the regular maintenance routine.

Tires on a 2022 Buick Trucks vehicle should be inspected before every drive and again before any longer trip. Look for cuts, bulges, embedded objects, irregular tread wear, sidewall cracking, and any sign that the tire is losing pressure. On modern tubeless radial applications like these, valve stem condition also deserves attention because it can become a leak point over time.

Frequent inspection is especially worthwhile on SUVs and crossovers that may carry family passengers or spend time on higher-speed roads. A quick walkaround catches problems early and helps prevent uneven wear from going unnoticed. On a vehicle that is driven infrequently, those visual checks matter just as much as scheduled service intervals.

Yes, the radial tires covered here for 2022 Buick Trucks are suitable for normal highway driving when they are the correct size, properly inflated, and in sound condition. Within the 245/45R20 Envision fitment, W-rated tires carry a 168 mph ceiling and Y-rated tires carry a 186-plus mph ceiling. Those ratings sit well above typical U.S. highway speeds, so real-world safety is more likely to depend on tire condition, inflation, alignment, and the vehicle’s overall mechanical health.

The practical point is not to chase the highest speed letter unless it matches your needs and the original fitment requirements. A correctly sized, healthy tire is more important than excess rating capacity on a Buick crossover used in everyday road conditions. Before any sustained highway trip, confirm pressure, inspect the tread and sidewalls, and check that all four tires match the application.

Inflation pressure for 2022 Buick Trucks should follow the vehicle placard or owner’s manual first, because factory pressure recommendations are tied to the exact model, wheel package, and load condition. In the covered 245/45R20 products, maximum load and pressure examples reach 1930 pounds at 50 psi and 1929 pounds at 50 psi. Those figures are tire limits, not a blanket operating pressure for every 2022 Buick Trucks model or size.

That distinction matters because a maximum sidewall pressure is different from the pressure Buick intended for everyday service. Use the vehicle’s specification for normal driving, then compare it against the tire manufacturer’s ratings to make sure the tire is operating in its proper range. Pressure should always be checked cold, especially before travel or after the vehicle has been sitting.

Before a longer drive in a 2022 Buick Trucks vehicle, inspect all four tires for cracking, cuts, punctures, bulges, and uneven wear, then confirm cold inflation pressure. Check the spare as well if the vehicle carries one, and make sure the valve stems are in good condition. On vehicles with multiple possible wheel packages, verify that all four tires match in size and type.

A longer-drive check should also include the rest of the vehicle, since tires are only one part of road readiness. Brake condition, fluid levels, battery health, and suspension behavior all affect how safely the Buick will travel at speed. Taking a few minutes to inspect the whole package reduces surprises and helps the tires perform the way they were designed to.
