2024 Buick Trucks Tire Fitment Guide

2024 Buick Trucks vehicles use seven sizes across four models: Enclave uses 255/55R20 and 255/65R18, Encore GX uses 245/45R19 and 225/55R18, Envision uses 245/45R20 and 235/60R18, and Envista uses 245/45R19, 225/55R18, and 225/60R17. The shared sizes are 245/45R19 and 225/55R18, both used by the Encore GX and Envista, while the remaining sizes are model-specific. Rim diameters span 17, 18, 19, and 20 inches.

That spread means a 2024 Buick Trucks tire search should begin with the exact model and the wheel diameter already on the vehicle, not just the model year. If your Buick has been fitted with a different wheel package than another trim of the same model, the alternate size may still be correct for that model but not for your specific wheels. Checking the sidewall on the current tire or the placard is the quickest way to confirm where to start.

On a 2024 Buick Trucks tire, 245/45R19 means the tire is 245 millimeters wide, has a 45-series aspect ratio, uses radial construction, and mounts on a 19-inch rim. Within this year and make, that size is shared by the Encore GX and Envista. Available examples in this size carry W and Y speed ratings, so the code gives you the base dimensional fit while the complete sidewall marking adds the tire’s service details.

For an Encore GX or Envista owner, that code matters more than appearance alone because a 19-inch tire cannot substitute for the same model’s 18-inch or 17-inch wheel package. It also helps explain why two tires in the same size can behave differently in everyday use: the dimensions stay the same, but speed rating, load specification, and tread category can change by product. Matching the full size code is the first step before comparing brands.

No, 2024 Buick Trucks models do not all use the same tire size. The Enclave and Envision each have their own model-specific size pairs, while the Encore GX and Envista share 245/45R19 and 225/55R18, and the Envista adds its own 225/60R17 fitment. Even within a single model, more than one factory wheel diameter can appear, so the same nameplate does not automatically mean one universal tire size.

That has a practical effect when replacing tires one at a time or shopping for a seasonal set. If you know only that you own a 2024 Buick Trucks crossover, there is still too much variation to choose correctly. Identifying the exact model gets you closer, but confirming whether the vehicle is on 17-, 18-, 19-, or 20-inch wheels is what prevents an expensive mismatch.

2024 Buick Trucks tire options here include blackwall and narrow whitewall sidewall styles. The 245/45R19 and 245/45R20 sizes are available in blackwall form from BFGoodrich and Nitto, while the 225/60R17 for the Envista appears with a narrow whitewall from Travelstar. Since all of these vehicles are modern crossovers, blackwall remains the mainstream appearance, while the narrow whitewall creates a more custom or style-driven look than a factory-neutral presentation.

Sidewall choice matters most when appearance is part of the goal rather than simply replacing worn tires with the same visual character. A blackwall usually keeps the look closest to what buyers expect on a contemporary Buick crossover, especially on larger 19- and 20-inch packages. A narrow whitewall can make sense for an owner who wants something more distinctive, but it should still be chosen only in the exact size that matches the wheel.

Three brands appear in the available 2024 Buick Trucks fitments here: BFGoodrich, Nitto, and Travelstar. BFGoodrich and Nitto cover the 245/45R19 and 245/45R20 sizes, while Travelstar appears in 225/60R17 for the Envista. The 19- and 20-inch sizes have the broadest brand coverage, which gives owners of those applications more room to compare tire character within the same basic dimensions.

Brand selection should follow size confirmation, not replace it. An Envision owner on 20-inch wheels can compare BFGoodrich and Nitto options within 245/45R20, but that same comparison does not apply to an Enclave on 18-inch wheels or an Envista on 17s. Once the correct size is established, the next useful comparison is sidewall style, speed rating, and whether the tire’s overall intent matches how the Buick is actually driven.

For 2024 Buick Trucks applications, both the BFGoodrich g-Force COMP-2 A/S and g-Force Phenom T/A appear in 245/45R19, and both also appear in 245/45R20. They share blackwall styling and similar rim-width compatibility where stated, but the Phenom T/A carries a 102Y rating in 245/45R19 and a 103Y rating in 245/45R20, while the COMP-2 A/S examples in those sizes carry W or Y-rated service depending on the exact fitment. The Phenom entries also show maximum load figures of 1,874 pounds at 50 psi in 19-inch form and 1,929 pounds at 50 psi in 20-inch form.

That means the choice between the two is less about basic fit and more about the detailed service description attached to the tire you are considering. A buyer comparing these within the same Buick size should read the full sidewall marking and product specs rather than assuming all BFGoodrich options in one size are interchangeable. Matching the tire to the intended use of the vehicle is more important than choosing by series name alone.

Rim-width guidance is available for some 2024 Buick Trucks sizes. The 245/45R19 products fit rims from 7.5 to 9.0 inches, the 245/45R20 products also fit rims from 7.5 to 9.0 inches, and the 225/60R17 narrow whitewall appears on a 6.5J rim. Those figures apply to the specific sizes where they appear and should not be transferred to the other Buick fitments.

Rim width matters because a tire can have the correct overall size code yet still be unhappy on a wheel that is too narrow or too wide for the tire’s approved range. If you are replacing tires on factory wheels, the existing wheel package usually keeps you in the right zone. If the wheels have been changed, confirm the wheel width directly before choosing a tire, especially on the 19- and 20-inch applications.

The available 2024 Buick Trucks products shown here do not indicate tube-type construction. The 245/45R19 and 245/45R20 tires are modern radial performance-style fitments, and the 225/60R17 Travelstar is also presented as a modern radial tire with a standard passenger-car service description. In practical terms, these are tubeless-style applications unless a specific wheel condition or specialty setup calls for something different.

Even so, the wheel itself still matters. A tire that is intended for tubeless service depends on the wheel bead seat and valve stem being in sound condition, so corrosion, damage, or an aging stem can create problems that look like a tire issue but are really a wheel issue. When replacing tires on a modern Buick crossover, include a close inspection of the wheel and valve hardware as part of the job.

A 2024 Buick Trucks should be stored on a clean, dry surface away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber prematurely. Keeping the tires properly inflated during storage helps the casing hold its shape, and moving the vehicle occasionally can reduce long-term stress in one contact patch area. Since every size here is radial, the storage focus is more about age and environmental exposure than about severe bias-ply flat spotting.

If the Buick will sit for months at a time, wash road salts and dressings off the tires first and check inflation periodically rather than leaving the vehicle untouched. Owners storing the vehicle over winter often benefit from placing it on a clean barrier surface instead of bare concrete and avoiding moisture swings in the storage area. Good storage habits do not stop aging, but they slow down the cosmetic and structural deterioration that shortens tire life.

Tires on a 2024 Buick Trucks are better judged by age, condition, and service history than by mileage alone, especially if the vehicle sees low annual use. A sensible rule is to begin evaluating them closely around five to seven years of age and to treat the ten-year mark as a point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the sidewall is the quickest way to identify when a tire was built.

That approach matters because many modern crossovers can accumulate very little mileage while still aging in place through heat cycles, UV exposure, and time. A tire that looks acceptable at a glance may still be old enough to deserve closer scrutiny before regular highway use. If your Buick is driven seasonally or sparingly, date-checking the tires can tell you more about replacement timing than tread depth alone.

Tires on a 2024 Buick Trucks should be inspected before every drive and again before any longer trip. Look for cuts, bulges, embedded debris, uneven wear, sidewall cracking, and pressure loss, and make sure each tire appears to be carrying its load evenly. On modern radial applications like these, a quick visual inspection plus a pressure check catches many problems before they become roadside issues.

A longer outing deserves a more careful look, including tread depth across the tire face and the condition of the valve stems. If one tire keeps losing pressure or shows wear on one edge, treat that as a clue to investigate alignment, wheel damage, or a puncture rather than simply adding air and continuing to drive. Regular inspection is the simplest habit that protects both ride quality and safety.

Yes, 2024 Buick Trucks tires in these sizes are suitable for normal highway use when they are the correct size, properly inflated, and in good condition. The available 245/45R19 and 245/45R20 products include W-rated tires up to 112 mph and Y-rated tires at 186+ mph, while the 225/60R17 Travelstar carries a T rating up to 118 mph. Those speed ratings are well above ordinary U.S. highway speeds, so real-world safety usually depends more on tire condition and the vehicle’s maintenance state than on the rating alone.

That does not mean any old tire in the right size is automatically road-ready. Age, underinflation, impact damage, and neglected alignment can all make a highway drive risky even when the sidewall size and speed symbol look correct. Before regular interstate use, confirm the tires are evenly worn, free of visible defects, and matched to the Buick’s actual wheel package rather than to another trim or model.

Inflation pressure for a 2024 Buick Trucks should follow the vehicle placard or owner’s manual for everyday use, because factory pressure targets are set around the vehicle’s weight distribution, ride tuning, and original wheel package. Tire service figures in the available products are not the same thing as recommended running pressure: the 225/60R17 Travelstar shows 1,709 pounds at 44 psi, the 245/45R19 g-Force Phenom T/A shows 1,874 pounds at 50 psi, and the 245/45R20 Phenom T/A shows 1,929 pounds at 50 psi.

Those figures are useful for understanding the tire’s rated capacity, but they should not be copied blindly from one size to another or used in place of Buick’s vehicle-specific recommendation. A crossover on 17-inch wheels can need a different pressure than the same nameplate on 19s or 20s. Start with the placard, then compare it with the tire maker’s guidance if you are changing to a different product series within the same size.

Before taking a 2024 Buick Trucks on a longer drive, inspect all four tires and the spare for proper inflation, visible cracking, cuts, bulges, uneven wear, and any object lodged in the tread. Make sure the valve stems are intact, the tread depth is still appropriate for wet-weather use, and the tire size on the vehicle matches the wheel package actually fitted. On a modern Buick crossover, that basic tire check should be part of a broader walk-around rather than an afterthought.

Longer drives also put more heat into the tires, so small issues that seem harmless around town can become bigger problems on the highway. If the Buick has recently hit a pothole, curbed a wheel, or developed a vibration, address that before the trip instead of hoping it will sort itself out. A careful pre-drive check reduces the odds of tire trouble and helps you catch suspension or wheel issues early.
