The 2024 Buick Trucks Enclave sits in the modern three-row crossover category, blending family-duty comfort with the upscale look expected from Buick’s top utility offerings. For buyers replacing tires on this exact model, the main fitment question is tied to wheel size rather than an old-style vintage sizing system. The 2024 Buick Trucks Enclave uses radial tires in either 255/55R20 or 255/65R18, depending on sub-model and wheel setup. Because both sizes are close in overall diameter but mount on different rim diameters, the real job is confirming the exact trim and wheel before choosing a replacement. That keeps fitment, appearance, and road manners aligned with the vehicle’s intended setup.
Which Tire Size Is Right for The 2024 Buick Trucks Enclave
The 2024 Buick Trucks Enclave uses two primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter. Both are radial metric sizes, but one fits an 18-inch rim and the other fits a 20-inch rim, so confirming the wheel setup matters before anything else. Once that is settled, the decision shifts to choosing the right replacement tire within the proper size.
Fit(s): Avenir, Essence, Essence Sport Touring Edition, and Premium
Construction: Radial|Rim: 20 in
255/55R20 is a metric radial size in which 255 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2024 Buick Trucks Enclave, this size belongs to models equipped with 20-inch wheels and keeps the fitment in a modern crossover-oriented format. Its lower profile compared with the 18-inch-wheel size gives the tire a different visual proportion without changing the vehicle into a different fitment family. Choosing this size starts with confirming that the Enclave actually has 20-inch rims installed.
255/65R18 is a metric radial size with a 255-millimeter nominal section width, a 65-series profile, radial construction, and an 18-inch rim diameter. On the 2024 Buick Trucks Enclave, this size is used on certain sub-model configurations that retain 18-inch wheels. It carries the same basic width as the 20-inch-wheel option but pairs that width with a taller sidewall and different wheel diameter. The practical choice is not between profiles on the same wheel, but between confirming the Enclave’s actual 18-inch wheel setup and then replacing the tire with the correct matching size.
Sub-model fitment on the 2024 Buick Trucks Enclave is not completely uniform, because some trims use one wheel-and-tire setup while others can appear with either of the two primary sizes. Checking the exact sub-model is the first step, but wheel diameter still needs to match before selecting tires.

2024 Buick Trucks Enclave Avenir
The 2024 Buick Trucks Enclave Avenir uses the 255/55R20 radial tire size. Tire selection here centers on replacing the 20-inch fitment with the same size and confirming that the vehicle still carries its intended wheel setup before purchase.
The 2024 Buick Trucks Enclave Essence can use either 255/55R20 or 255/65R18 radial tires, depending on the wheel package on the vehicle. That makes wheel confirmation especially important, since tire choice begins with the actual rim diameter rather than the trim name alone.
2024 Buick Trucks Enclave Essence Sport Touring Edition
The 2024 Buick Trucks Enclave Essence Sport Touring Edition uses the 255/55R20 radial size. The key buying step is matching that 20-inch fitment and checking that no wheel changes have been made that would alter the required replacement size.
The 2024 Buick Trucks Enclave Premium can use either 255/55R20 or 255/65R18 radial tires. Because both sizes belong to different rim diameters, tire selection depends on verifying the exact wheels on the vehicle before comparing replacement options.
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)

Frequently Asked Questions
These FAQs focus on the two tire sizes used on the 2024 Buick Trucks Enclave, how sub-model and wheel diameter affect fitment, and what to check when choosing replacement tires for daily road use.
Tire Size & Fitment
What tire size fits a 2024 Buick Trucks Enclave?
The 2024 Buick Trucks Enclave uses either 255/55R20 or 255/65R18 tires. Both are radial metric sizes, and the correct one depends on the sub-model and the wheel package installed on the vehicle.
The important distinction is that these sizes do not mount on the same rim diameter. A 255/55R20 fits a 20-inch wheel, while a 255/65R18 fits an 18-inch wheel, so the safest starting point is to confirm the actual wheels on the Enclave before choosing replacement tires.
What size rim does a 2024 Buick Trucks Enclave use?
A 2024 Buick Trucks Enclave uses either an 18-inch or 20-inch rim, depending on the exact trim and wheel setup. The 255/65R18 tire belongs on an 18-inch rim, while the 255/55R20 tire belongs on a 20-inch rim.
That rim diameter difference is the main fitment checkpoint on this model. Before replacing tires, verify the wheel size stamped on the wheel or read the existing tire sidewall, especially on Essence and Premium models that can appear with more than one factory-style size.
Do all 2024 Buick Trucks Enclave sub-models use the same tire size?
No, not every 2024 Buick Trucks Enclave sub-model uses the same tire size. Avenir and Essence Sport Touring Edition use 255/55R20, while Essence and Premium can use either 255/55R20 or 255/65R18 depending on the wheel setup.
That means trim name alone may not be enough to order tires confidently on every Enclave. For models that can carry either size, checking the vehicle’s installed wheels and the current tire sidewall is the practical way to avoid choosing an 18-inch tire for a 20-inch rim or the reverse.
Choosing the Right Tire
What should I consider when choosing a 255/55R20 tire for a 2024 Buick Trucks Enclave?
Start by confirming that the 2024 Buick Trucks Enclave actually uses the 255/55R20 size and 20-inch wheels. This size appears on the Avenir and Essence Sport Touring Edition, and it can also apply to certain Essence and Premium models.
Once size is confirmed, compare the tire’s intended use, load suitability, and overall replacement character for a three-row crossover. A matching size keeps the fitment in the right profile family, while checking wheel condition, alignment, and any prior wheel changes helps avoid problems that tire size alone cannot answer.
What should I consider when choosing a 255/65R18 tire for a 2024 Buick Trucks Enclave?
A 255/65R18 tire is the correct choice only for a 2024 Buick Trucks Enclave equipped with 18-inch wheels. On this model, that size is associated with certain Essence and Premium configurations rather than every trim across the lineup.
The practical focus is replacing the tire within the same 18-inch fitment instead of comparing it loosely with the 20-inch option. Verifying the actual wheel diameter, checking for any aftermarket wheel swap, and making sure the vehicle still has adequate clearance and proper inflation are sensible steps before installation.
How do I choose between the available tires for a 2024 Buick Trucks Enclave?
Choosing among tires for a 2024 Buick Trucks Enclave begins with selecting the correct size: 255/55R20 or 255/65R18. After that, the comparison should center on replacement type, intended road use, and whether the tire matches the wheel diameter and service demands of a three-row crossover.
A useful approach is to confirm the Enclave’s exact trim and installed wheels, then compare the tire options that remain in the proper size. Looking at construction consistency, load-related suitability, and the vehicle’s day-to-day use will usually be more helpful than focusing only on appearance or sidewall profile.
Restoration & Appearance
Does correct tire fitment matter for a 2024 Buick Trucks Enclave restoration or refurbishment?
Yes, correct tire fitment still matters when refreshing or refurbishing a 2024 Buick Trucks Enclave, even though this is a modern utility vehicle rather than a vintage restoration candidate. Using the proper 255/55R20 or 255/65R18 size helps preserve the intended relationship between wheel diameter, sidewall profile, and overall stance.
Appearance can change noticeably if the wrong rim-and-tire combination is installed, especially on trims designed around 20-inch wheels. A careful refurbishment should keep the tire size aligned with the Enclave’s actual wheel setup, while any appearance-focused change should also be checked for clearance, speedometer consistency, and road-use practicality.
How does tire size affect the appearance of a 2024 Buick Trucks Enclave?
Tire size affects the 2024 Buick Trucks Enclave’s visual balance because 255/55R20 and 255/65R18 pair the same basic width with different wheel diameters and sidewall proportions. The 20-inch setup presents more wheel visually, while the 18-inch setup carries a taller-looking sidewall.
That appearance difference is normal only when the tire matches the correct wheel package for the vehicle. If an Enclave has had wheel changes, selecting tires by trim name alone can create a mismatched look, so confirming the actual rim diameter is the best way to keep the vehicle’s proportions looking right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Buick Trucks Enclave?
Yes, modifications can affect tire fitment on a 2024 Buick Trucks Enclave even when the original tire sizes are known. Wheel changes, suspension alterations, alignment changes, or body modifications can all influence how a 255/55R20 or 255/65R18 tire sits and clears the vehicle.
An Enclave with aftermarket wheels may no longer match the original rim width or offset expectations of the stock setup. Checking wheel diameter, wheel width, turning clearance, and fender clearance before installing new tires is especially important if the vehicle no longer carries its original-style wheel-and-suspension configuration.
What should I inspect before driving a 2024 Buick Trucks Enclave on new tires?
Before driving a 2024 Buick Trucks Enclave on new tires, inspect that the tire size matches the wheel diameter and that all four tires are properly seated, inflated, and free from visible defects. It is also wise to confirm that the wheels themselves are in good condition.
A quick road-use check should include alignment feel, steering response, and any sign of rubbing during full-lock turns or over suspension movement. Looking at lug torque, tire pressure, and even tread contact across the first miles can help catch setup issues early, especially after replacing worn tires or changed wheels.
How often should tires on a 2024 Buick Trucks Enclave be inspected?
Tires on a 2024 Buick Trucks Enclave should be inspected regularly rather than only at replacement time. Frequent visual checks for uneven wear, cuts, punctures, sidewall damage, and pressure loss are especially important on a heavier three-row vehicle that may see family, highway, and cargo use.
A practical routine is to check pressure and condition monthly and again before longer trips. Paying attention to tread wear patterns can also reveal alignment or suspension issues, and those concerns should be addressed early so the next set of 255/55R20 or 255/65R18 tires wears evenly and maintains predictable road behavior.
