The 2014 Buick Trucks Enclave sits in the three-row crossover era when quiet road manners, upscale trim, and family travel comfort mattered as much as outright utility. Its long, rounded profile and car-based chassis gave it a more refined role than a traditional truck-based SUV, which makes tire choice especially important to the way it looks and drives. This Enclave uses radial tire fitments in three sizes: 255/65R18, 255/60R19, and 255/55R20. That gives owners a clear choice between different wheel diameters rather than a switch between bias-ply and radial construction. The key is matching the exact sub-model and wheel setup before comparing tire style, road-use priorities, and replacement options.
Which Tire Size Is Right for The 2014 Buick Trucks Enclave
Three tire sizes apply to the 2014 Buick Trucks Enclave, and the right one depends on the exact sub-model and wheel diameter already on the vehicle. All three are radial sizes, but they are built for different rims: 18-inch, 19-inch, and 20-inch. Before choosing a tire, confirm whether the Enclave is a Convenience, Leather, or Premium model and verify the actual wheel size currently installed.
255/65R18 is a modern metric radial size. The 255 identifies the nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On the 2014 Buick Trucks Enclave, this size matters because it is tied to an 18-inch wheel setup rather than the 19-inch or 20-inch alternatives used elsewhere in the model range. Choose this size only after confirming that the vehicle is equipped with the matching 18-inch rims, since the overall tire dimensions stay close across the Enclave's fitments while wheel diameter changes.
255/55R20 is also a modern metric radial size, with a 255-millimeter nominal width, a 55 aspect ratio, radial construction, and a 20-inch rim diameter. For the 2014 Buick Trucks Enclave, this size represents one of the larger-wheel fitments used on certain upper trims. Its role is not interchangeable with the 18-inch or 19-inch primary sizes unless the wheel itself matches. This is the size to evaluate when the vehicle already carries 20-inch wheels and you want to keep the proper fitment relationship between tire dimensions and the Enclave's original wheel diameter choice.
255/60R19 follows the same modern metric radial sizing convention, combining a 255-millimeter nominal width with a 60 aspect ratio on a 19-inch rim. On the 2014 Buick Trucks Enclave, it serves as the middle wheel-diameter fitment used on certain Leather and Premium configurations. That makes it a size-specific decision tied first to the wheel on the vehicle, not just to the model name alone. Use this size when the Enclave is equipped with 19-inch rims and you want to stay with the intended fitment range for that particular setup.
Sub-model fitment matters on the 2014 Buick Trucks Enclave because tire size changes with trim and wheel diameter. The Convenience model uses one size, while Leather and Premium models can use either of two larger-wheel fitments, so confirming the exact sub-model and installed rims is the first step.

2014 Buick Trucks Enclave Convenience
The 2014 Buick Trucks Enclave Convenience uses a single radial tire fitment built around an 18-inch wheel. That makes tire selection more straightforward, but the wheel diameter should still be confirmed before replacement, especially if the vehicle has ever been updated with different wheels.
The 2014 Buick Trucks Enclave Leather can use either of two radial tire sizes, depending on whether it has 19-inch or 20-inch wheels. Tire selection starts with verifying the wheel diameter on the vehicle, since the correct replacement depends on that existing setup rather than the trim name alone.
The 2014 Buick Trucks Enclave Premium also uses two possible radial fitments tied to 19-inch or 20-inch rims. For this sub-model, the practical step is confirming the actual wheel size before choosing tires, especially on vehicles that may have seen wheel changes over time.
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.
Frequently Asked Questions
These FAQs for the 2014 Buick Trucks Enclave focus on exact tire size by sub-model, wheel-diameter fitment, choosing between the three radial sizes, and the inspection points that matter before regular driving or a longer trip.
Tire Size & Fitment
What tire size fits a 2014 Buick Trucks Enclave?
The 2014 Buick Trucks Enclave uses three radial tire sizes: 255/65R18, 255/60R19, and 255/55R20. The right size depends on the sub-model and, just as importantly, the wheel diameter on the vehicle. Convenience models use 255/65R18, while Leather and Premium models use either 255/60R19 or 255/55R20.
The safest way to narrow the choice is to confirm the Enclave's installed wheel size before ordering tires. These three sizes are very close in overall diameter, but they are built for different 18-inch, 19-inch, and 20-inch rims, so selecting by model name alone can lead to the wrong fitment.
What size rim does a 2014 Buick Trucks Enclave use?
A 2014 Buick Trucks Enclave can use 18-inch, 19-inch, or 20-inch rims, depending on the sub-model and wheel setup. The 255/65R18 tire pairs with an 18-inch rim, the 255/60R19 pairs with a 19-inch rim, and the 255/55R20 pairs with a 20-inch rim.
Rim diameter should be checked directly on the wheel or current tire before replacement. Leather and Premium models can appear similar while using different wheel diameters, and any Enclave that has received aftermarket wheels should be measured rather than assumed from trim alone.
Do all 2014 Buick Trucks Enclave sub-models use the same tire size?
No. The 2014 Buick Trucks Enclave Convenience uses 255/65R18, while the Leather and Premium sub-models use either 255/60R19 or 255/55R20. That means tire fitment is not shared across the full Enclave range, even though all of the sizes are radial and close in overall height.
Sub-model identification helps, but wheel verification is still the deciding step. Leather and Premium vehicles can use more than one tire size, so checking the actual rim diameter on the vehicle is more reliable than guessing from appearance, trim level, or prior replacement history.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Buick Trucks Enclave?
Start with the correct size for the vehicle's wheel diameter: 255/65R18, 255/60R19, or 255/55R20. On the 2014 Buick Trucks Enclave, the main selection issue is matching the existing rim size and sub-model fitment, since all primary choices are modern radial tires rather than different constructions.
After confirming size, think about how the Enclave is used. Daily highway driving, family travel, seasonal road conditions, and ride preferences all affect which tire characteristics matter most. Any Enclave with non-original wheels or suspension changes should have wheel clearance and tire-to-body spacing checked before replacement.
How do I choose between the available 2014 Buick Trucks Enclave tire sizes?
The three Enclave sizes are chosen by wheel diameter, not by personal preference alone. Use 255/65R18 only on 18-inch rims, 255/60R19 only on 19-inch rims, and 255/55R20 only on 20-inch rims. Convenience, Leather, and Premium trims do not all share one universal tire size.
Because the overall diameters are very close, the biggest practical difference is the wheel each tire is designed to fit. That means a buyer should treat the wheel as the starting point, then compare tire options within that exact size rather than trying to move between 18-inch, 19-inch, and 20-inch fitments casually.
How do I choose between the available radial tires for a 2014 Buick Trucks Enclave?
Since every primary fitment on the 2014 Buick Trucks Enclave is radial, the first decision is not construction but exact size. Once the correct 255/65R18, 255/60R19, or 255/55R20 size is confirmed, compare tires by the type of road use the vehicle sees most often and by the ride feel you want to preserve.
A family-oriented crossover like the Enclave usually benefits from a tire that matches its comfort-focused role and wheel diameter without changing the fitment baseline. If the vehicle has seen wheel swaps, verify that the current setup still clears suspension and body components before choosing among replacement options in that size.
Restoration & Appearance
Does correct tire fitment matter for a 2014 Buick Trucks Enclave restoration or preservation project?
Yes. Even on a newer collector or preservation-minded vehicle, correct tire fitment helps maintain the intended stance, wheel relationship, and overall presentation. For a 2014 Buick Trucks Enclave, that means staying with the proper radial size for the actual wheel setup: 255/65R18, 255/60R19, or 255/55R20.
Appearance can shift noticeably when wheel diameter and tire size no longer match the original trim-level setup. Owners focused on keeping the Enclave visually consistent should verify the sub-model and installed rims first, then choose a replacement tire that preserves the established proportions rather than mixing sizes casually.
Which tire size should I keep for a period-appropriate 2014 Buick Trucks Enclave appearance?
A period-appropriate appearance starts with retaining the wheel diameter and matching tire size already intended for that version of the 2014 Buick Trucks Enclave. Convenience models use 255/65R18, while Leather and Premium models use either 255/60R19 or 255/55R20, depending on the wheel package on the vehicle.
For appearance-focused owners, the goal is consistency between trim, rim diameter, and tire profile rather than changing to a different Enclave size because it seems close. If exact historical presentation matters, compare the current wheel setup to original vehicle references before moving away from the tire size tied to that rim.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Buick Trucks Enclave?
Yes. Any change to wheels, suspension height, alignment settings, or body clearance can affect tire fitment on a 2014 Buick Trucks Enclave. That matters because the Enclave already uses three different rim diameters, so a modified vehicle may no longer match the size normally associated with its original sub-model.
Wheel diameter is only part of the equation. If the Enclave has aftermarket wheels, lowered suspension, or repaired body panels, check clearance at full steering lock and through normal suspension travel. Tire replacement should follow the actual setup on the vehicle, not just the trim designation on paper.
What should I inspect before driving a 2014 Buick Trucks Enclave on new tires?
Before regular driving, inspect air pressure, valve stems, lug torque, tread seating, and overall clearance around the suspension and fenders. A 2014 Buick Trucks Enclave should also have its wheel diameter and tire size confirmed so the new tires match the proper 18-inch, 19-inch, or 20-inch rim setup.
A short road test can reveal vibration, pull, rubbing, or steering issues that deserve attention before longer use. It also helps to inspect the older spare, if equipped, and look over the alignment and brake condition, since fresh tires can highlight problems that were less noticeable on worn ones.
What should I check before a longer drive in a 2014 Buick Trucks Enclave?
Before a longer trip, check tread condition, air pressure, sidewall condition, and any signs of cuts, bulges, or uneven wear. On a 2014 Buick Trucks Enclave, it is also smart to confirm that all four road tires are the same size and appropriate for the wheel diameter the vehicle is actually using.
Longer highway use puts more heat and load into the tire than short local driving, so small issues become more noticeable. An Enclave that has sat for long periods should also be checked for age-related cracking and slow air loss, especially if it is driven infrequently or stored through changing seasons.
