The 2017 Buick Trucks Enclave sits in the full-size crossover era when three-row comfort, quiet highway manners, and upscale trim levels became central to family vehicle design. For many owners, it balances modern road use with the need to keep the vehicle riding and looking right across different wheel packages. Tire fitment centers on two radial sizes, 255/60R19 and 255/55R20, and the right choice depends first on the exact sub-model and wheel diameter on the vehicle. That makes this page less about vintage construction decisions and more about confirming the correct size, understanding the metric sizing, and selecting a tire that matches the Enclave's intended use.
Which Tire Size Is Right for The 2017 Buick Trucks Enclave
The 2017 Buick Trucks Enclave uses two primary tire sizes, and the first step is confirming whether the vehicle is on a 19-inch or 20-inch wheel. Fitment varies by sub-model and wheel package, so identifying the exact Enclave configuration matters before comparing tires. Once the correct size is confirmed, the real decision becomes choosing the right radial tire within that fitment for appearance, use, and wheel compatibility.
255/60R19 is a metric radial size in which 255 identifies the nominal section width in millimeters, 60 is the aspect ratio, R designates radial construction, and 19 is the wheel diameter in inches. On the 2017 Buick Trucks Enclave, this size is one of the two primary fitments and belongs on a 19-inch wheel. Its meaning is straightforward, but the key practical point is making sure the vehicle actually carries the 19-inch setup. This size should be chosen when the Enclave's wheel diameter and sub-model fitment align with the 19-inch package.
255/55R20 is also a metric radial size, with the same 255-millimeter nominal width but a 55-series profile and a 20-inch wheel diameter. For the 2017 Buick Trucks Enclave, this size applies to configurations equipped with the 20-inch wheel package rather than the 19-inch setup. The sizing format is familiar to modern buyers, but the important distinction is that wheel diameter determines whether this fitment belongs on the vehicle. This size should be evaluated only after confirming that the Enclave uses the 20-inch wheel and the matching sub-model configuration.
Sub-model fitment on the 2017 Buick Trucks Enclave is not identical across the range, because some trims can use either a 19-inch or 20-inch tire package. Checking the exact sub-model helps narrow the correct tire size before comparing replacement options.

2017 Buick Trucks Enclave Convenience
The 2017 Buick Trucks Enclave Convenience uses the 255/60R19 radial fitment. Tire selection here is mainly about staying with the correct 19-inch size and matching the wheel setup already on the vehicle before moving on to brand or tread preferences.
The 2017 Buick Trucks Enclave Leather can use either 255/60R19 or 255/55R20, depending on the wheel package installed. That makes wheel-diameter confirmation especially important before selecting tires, since both fitments are radial but they are not meant for the same rim size.
The 2017 Buick Trucks Enclave Premium can also use either 255/60R19 or 255/55R20. The practical step is confirming whether the vehicle carries 19-inch or 20-inch wheels, then choosing within that correct size rather than assuming every Premium model uses the same tire.
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
Owners of a 2017 Buick Trucks Enclave usually need clarity on tire size, wheel diameter, sub-model differences, and what to inspect before putting the vehicle back into regular road use. These questions focus on fitment first, then on practical tire selection and maintenance.
Tire Size & Fitment
What tire size fits a 2017 Buick Trucks Enclave?
The 2017 Buick Trucks Enclave uses two primary tire sizes: 255/60R19 and 255/55R20. Both are radial fitments, and the correct one depends on the Enclave's sub-model and wheel package rather than the model name alone.
Choosing between them starts with confirming the wheel diameter already on the vehicle. A 19-inch wheel takes 255/60R19, while a 20-inch wheel takes 255/55R20. Checking the existing tire sidewall and wheel size is the simplest way to avoid ordering the right width in the wrong rim diameter.
What size rim does a 2017 Buick Trucks Enclave use?
A 2017 Buick Trucks Enclave uses either a 19-inch or 20-inch rim, depending on the tire size and sub-model configuration. The 255/60R19 fitment belongs to a 19-inch wheel, and the 255/55R20 fitment belongs to a 20-inch wheel.
Rim diameter is the first fitment checkpoint because the two tire sizes are not meant for the same wheel. Before comparing replacement tires, inspect the wheel itself and confirm the current tire size on the sidewall. That matters even more on Leather and Premium models, which can appear similar while carrying different wheel packages.
Do all 2017 Buick Trucks Enclave sub-models use the same tire size?
No, all 2017 Buick Trucks Enclave sub-models do not use the same tire size. The Convenience sub-model uses 255/60R19, while the Leather and Premium sub-models can use either 255/60R19 or 255/55R20 depending on wheel package.
That means trim name alone is not always enough to pick a tire. On Leather and Premium models, the actual wheel diameter on the vehicle needs to be verified before choosing a replacement. Matching the new tire to the existing wheel is more important than assuming every Enclave in a given trim left the road with identical fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Buick Trucks Enclave?
Start with the correct primary size for the vehicle: 255/60R19 or 255/55R20. Both are radial fitments, so the main decision is not construction type but confirming the proper wheel diameter and selecting a tire that matches the Enclave's intended road use.
After size is confirmed, compare how the vehicle is driven and whether ride comfort, highway use, or seasonal conditions matter most. It also helps to inspect the current wheel setup for any aftermarket changes. A tire in the correct nominal size still needs to match the vehicle's actual wheels and leave proper clearance through steering and suspension travel.
How do I choose between the available 255/60R19 and 255/55R20 tires for a 2017 Buick Trucks Enclave?
The right choice is determined first by wheel diameter, not by preference between the two sizes. A 2017 Buick Trucks Enclave with 19-inch wheels uses 255/60R19, while one with 20-inch wheels uses 255/55R20, so each size belongs to a different wheel package.
Once that is settled, compare tires within the correct size rather than across both sizes. Looking at the existing tires can also reveal whether the vehicle has been changed from its original wheel package. That simple check helps prevent a mismatch between tire and rim, especially on Leather and Premium models that can carry either fitment.
What rim-fitment details should I compare when choosing 2017 Buick Trucks Enclave tires?
The most important rim-fitment detail is diameter: 19 inches for 255/60R19 and 20 inches for 255/55R20. On a 2017 Buick Trucks Enclave, that single measurement determines which of the two primary tire sizes belongs on the vehicle.
After diameter, look for any signs that the Enclave has aftermarket wheels or changed suspension height. Those changes can affect how a tire sits in the wheel opening and how much clearance remains at full steering lock. Even when the sidewall size looks familiar, the wheel setup on the vehicle still deserves a quick verification before replacement.
Restoration & Appearance
Does correct tire fitment matter for a 2017 Buick Trucks Enclave restoration or preservation project?
Yes, correct tire fitment still matters on a 2017 Buick Trucks Enclave, even though it is a modern radial application rather than a vintage bias-ply one. The right size preserves the intended relationship between wheel diameter, sidewall profile, and the vehicle's overall stance.
For a preservation-minded Enclave, the first goal is keeping the correct 19-inch or 20-inch fitment with the matching tire size. That avoids the visual and practical issues that come from mixing wheel packages. Owners seeking a highly exact appearance standard should also compare the vehicle against original sales literature or marque-specific reference material.
Which tire size suits a period-appropriate 2017 Buick Trucks Enclave appearance?
A period-appropriate appearance starts with using the size that matches the vehicle's actual wheel package: 255/60R19 on a 19-inch wheel or 255/55R20 on a 20-inch wheel. Both sizes are modern metric radials and suit the Enclave's original design era.
Appearance on this vehicle is shaped more by keeping the correct wheel-and-tire relationship than by choosing between vintage-style constructions or sidewall treatments. A change in rim diameter alters the look immediately, so the safest visual approach is confirming what the vehicle currently uses and staying within that proper fitment unless a deliberate wheel conversion is planned.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Buick Trucks Enclave?
Yes, modifications can affect tire fitment on a 2017 Buick Trucks Enclave. Aftermarket wheels, changes in wheel offset, suspension lowering, or other ride-height alterations can all influence whether 255/60R19 or 255/55R20 still has proper clearance.
Even when the tire size matches a known Enclave fitment, the actual vehicle setup may no longer be standard. Checking clearance at full steering lock and through suspension movement is a smart step before committing to replacement tires. That is especially important when a used Enclave has changed hands and its wheel package history is not immediately obvious.
What should I inspect before driving a 2017 Buick Trucks Enclave on new tires?
Before driving a 2017 Buick Trucks Enclave on new tires, inspect the wheel diameter, confirm the tire size matches that wheel, and look over the suspension and steering for obvious wear or interference points. Tire pressure should also be set correctly before the first regular road use.
A quick visual inspection for rubbing marks, damaged wheels, uneven old-tire wear, and loose or worn steering parts can prevent fitment surprises after installation. It also helps to recheck lug torque after initial driving and pay attention to how the vehicle tracks and turns. Any vibration, pull, or contact noise deserves immediate attention.
How often should tires on a 2017 Buick Trucks Enclave be inspected?
Tires on a 2017 Buick Trucks Enclave should be inspected regularly, not just when tread looks low. Routine checks should include tread wear, pressure, cuts, bulges, cracking, and any sign of air loss, especially if the vehicle sits for stretches between longer drives.
Regular inspection matters because size alone does not guarantee safe road use. A 255/60R19 or 255/55R20 tire can still be unsuitable if age, storage conditions, or impact damage have compromised it. Looking over the tires before trips and at normal service intervals helps catch problems early and keeps the Enclave's ride and handling more consistent.
