The 2016 Buick Trucks Enclave sits in the three-row crossover market with a strong emphasis on comfort, quiet highway manners, and upscale family use. Buyers looking at this exact Enclave usually are not sorting through vintage sizing conventions or bias-ply choices, but they do need to match the vehicle to the correct wheel and trim-specific tire size. This model uses radial tire fitments in 255/65R18, 255/60R19, or 255/55R20 depending on sub-model and wheel setup. That means the key decision is confirming whether the Enclave carries 18-, 19-, or 20-inch wheels. Once that is settled, the focus shifts to maintaining the intended stance, clearance, and overall driving character.
Which Tire Size Is Right for The 2016 Buick Trucks Enclave
Three primary tire sizes apply to the 2016 Buick Trucks Enclave, and they are tied to sub-model and wheel diameter rather than to different tire constructions. All three are radial fitments, but the first step is confirming whether your Enclave is equipped with 18-inch, 19-inch, or 20-inch wheels. After that, the real decision becomes selecting the right tire within that exact size and making sure the vehicle has not been altered from its intended wheel setup.
A 255/65R18 tire uses a 255-millimeter section width, a 65-series aspect ratio, radial construction, and an 18-inch rim. On the 2016 Buick Trucks Enclave, this size is one of the model's standard radial fitments and is tied to a specific wheel diameter rather than to a different construction type. Its metric format is familiar to modern SUV and crossover owners, so the main concern is straightforward fitment. This size is the right place to start when the Enclave has 18-inch wheels and you want to preserve the intended overall tire profile for that setup.
A 255/60R19 tire keeps the same 255-millimeter nominal width but pairs it with a 60-series profile on a 19-inch rim. For the 2016 Buick Trucks Enclave, this is a primary radial fitment used on certain sub-models, so it should be selected by wheel and trim confirmation rather than by appearance alone. The sizing convention is modern and easy to read, but the 19-inch rim requirement is the critical detail. This size makes sense when the vehicle is already equipped with the corresponding 19-inch wheel package and you want to stay with that factory-style fitment approach.
A 255/55R20 tire uses the same nominal 255-millimeter width with a shorter 55-series profile and a 20-inch rim diameter. On the 2016 Buick Trucks Enclave, this radial size belongs to specific sub-model applications and depends on the vehicle carrying the correct 20-inch wheels. The lower-profile metric format still falls within the Enclave's primary fitment range, but it is not interchangeable with the smaller-rim sizes without wheel changes. This is the size to evaluate when the vehicle has 20-inch wheels and you want to maintain the look and fitment intended for that configuration.
Tire fitment on the 2016 Buick Trucks Enclave varies by sub-model, so confirming the exact trim is important before choosing a replacement. The biggest distinction is wheel diameter, since this Enclave uses 18-, 19-, and 20-inch radial tire packages across the covered sub-model range.

2016 Buick Trucks Enclave Convenience
The 2016 Buick Trucks Enclave Convenience uses its own single radial tire size and wheel package, making trim identification fairly straightforward. Once the Convenience model is confirmed, the focus shifts to matching that exact size and checking that the vehicle still carries its intended wheel diameter.
The 2016 Buick Trucks Enclave Leather uses a single radial tire size tied to its specific wheel diameter. That makes tire selection relatively simple as long as the vehicle has not been changed to a different wheel package from another Enclave trim.
The 2016 Buick Trucks Enclave Leather Tuscan Edition uses a dedicated radial tire size associated with its larger wheel setup. Choosing tires for this version starts with confirming the current wheel diameter, then staying with the matching size to preserve proper proportions and clearance.
The 2016 Buick Trucks Enclave Premium can use more than one primary radial tire size, so this trim needs extra wheel verification before ordering tires. The deciding factor is whether the vehicle is equipped with the 19-inch or 20-inch setup, since both appear within the Premium range.
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
Questions about 2016 Buick Trucks Enclave tires usually come down to trim-specific sizing, wheel diameter, and how to confirm the right radial fitment before replacement. The FAQs below focus on size meaning, sub-model differences, tire selection, and practical checks for fitment and road use.
Tire Size & Fitment
What tire size fits a 2016 Buick Trucks Enclave?
The 2016 Buick Trucks Enclave uses three primary tire sizes: 255/65R18, 255/60R19, and 255/55R20. All of them are radial sizes, and the correct one depends on the Enclave sub-model and wheel package rather than on a choice between different tire constructions.
The most important step is confirming the exact trim level and the actual wheel diameter on the vehicle. A Convenience model uses a different setup than a Leather Tuscan Edition, and the Premium trim can appear with either 19-inch or 20-inch wheels, so the tire should be matched to the current wheel and vehicle configuration.
What size rim does a 2016 Buick Trucks Enclave use?
A 2016 Buick Trucks Enclave can use 18-inch, 19-inch, or 20-inch rims depending on sub-model. Those rim diameters correspond directly to the three primary tire sizes: 255/65R18, 255/60R19, and 255/55R20.
Wheel diameter is the first fitment detail to verify before shopping for replacement tires. Looking only at the model year and name is not enough here, because Enclave fitment changes across the trim range. Checking the wheel itself and the tire sidewall helps prevent choosing a size meant for a different sub-model or wheel package.
Why does the 2016 Buick Trucks Enclave have more than one tire size?
More than one tire size appears on the 2016 Buick Trucks Enclave because different sub-models use different wheel diameters. The Enclave range includes 18-inch, 19-inch, and 20-inch fitments, and the tire size changes accordingly while remaining a radial construction across the board.
That means tire selection starts with identifying the exact Enclave trim and confirming the wheels currently on the vehicle. A Premium model adds another layer because it can use either 255/60R19 or 255/55R20. Any prior wheel swap or accessory package should be checked before treating one size as universal across the full model line.
Choosing the Right Tire
What should I consider when choosing a 255/65R18 tire for a 2016 Buick Trucks Enclave?
A 255/65R18 tire should be chosen only for a 2016 Buick Trucks Enclave that actually uses the 18-inch wheel package, such as the Convenience trim. The key points are keeping the exact size, confirming radial construction, and making sure the wheel diameter matches the tire before comparing individual replacement options.
Once the fitment is confirmed, compare tires with the vehicle's intended use in mind, including everyday road driving, ride preference, and wheel compatibility. It also helps to inspect whether the Enclave still has its original wheel setup, since an aftermarket wheel change can make the door-jamb model name less useful than the tire sidewall and wheel measurement.
What should I consider when choosing a 255/60R19 or 255/55R20 tire for a 2016 Buick Trucks Enclave?
For a 2016 Buick Trucks Enclave, the first question is whether the vehicle is set up for 255/60R19 on a 19-inch rim or 255/55R20 on a 20-inch rim. Both are primary radial fitments, and each belongs to a specific wheel package rather than being a casual style-based substitution.
After wheel diameter is verified, compare tires within that exact size so the Enclave keeps the proper overall fitment for its setup. This matters especially on Premium models, where either size may be correct. Clearance, suspension condition, and any non-original wheels should be reviewed before moving ahead with a tire intended for a different rim diameter.
How do I choose between the available tire sizes for a 2016 Buick Trucks Enclave?
The available tire sizes for a 2016 Buick Trucks Enclave are not interchangeable choices in the usual sense. They are trim- and wheel-specific fitments: 255/65R18 for an 18-inch setup, 255/60R19 for a 19-inch setup, and 255/55R20 for a 20-inch setup.
Choosing between them really means identifying which wheel package your Enclave already has. Once that is confirmed, stay within the matching size and compare replacement tires in that format. Trying to select a size by appearance alone can create unnecessary fitment issues, especially if the vehicle has seen wheel changes since it left its original trim configuration.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Buick Trucks Enclave restoration?
Correct tire fitment still matters on a 2016 Buick Trucks Enclave, even though it is a modern radial-fitment vehicle rather than a vintage bias-ply application. The right size helps preserve the intended relationship between the tire, wheel opening, and wheel package used on the specific Enclave trim.
Appearance on a later vehicle like this is closely tied to keeping the proper 18-, 19-, or 20-inch setup in place. A Convenience model and a Leather Tuscan Edition do not share the same visual stance, so trim-appropriate sizing is an important part of returning the vehicle to a coherent factory-era presentation.
Which tire should I choose for a period-style 2016 Buick Trucks Enclave?
A period-style tire choice for a 2016 Buick Trucks Enclave starts with using the exact radial size tied to the vehicle's trim and wheel diameter. That means 255/65R18, 255/60R19, or 255/55R20 depending on the sub-model and current wheel setup.
For a restoration-oriented result, the goal is usually to preserve the Enclave's original-era proportions rather than experiment with alternate diameters. Checking trim, wheel size, and the vehicle's present configuration will do more for an authentic appearance than simply choosing a tire with a similar width while overlooking the intended rim diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Buick Trucks Enclave?
Yes, modifications can affect tire fitment on a 2016 Buick Trucks Enclave. Wheel changes, suspension alterations, lowering, or non-original offsets can all change how an otherwise correct size sits in the wheel opening, even when the tire code looks close to one of the Enclave's original radial fitments.
That is especially important on a model that already spans 18-, 19-, and 20-inch factory wheel packages. Any Enclave with aftermarket wheels should be checked for actual rim diameter and clearance at the fenders and steering components. Matching the tire to the current hardware matters more than assuming the original trim designation still tells the whole story.
What should I inspect before driving a 2016 Buick Trucks Enclave on new tires?
Before driving a 2016 Buick Trucks Enclave on new tires, inspect wheel condition, confirm the tire size matches the wheel diameter, and make sure inflation is set correctly for the vehicle's needs. It is also wise to look over the suspension and steering for worn parts that could affect how the new tires behave on the road.
A careful walkaround should include checking for rubbing at full steering lock and verifying there is no contact at the fenders or inner liners. Tire service on a trim-specific Enclave is not only about mounting the new set; it is also about making sure the vehicle remains stable, properly aligned, and free from clearance issues.
What should I check before a longer drive in a 2016 Buick Trucks Enclave?
Before a longer drive in a 2016 Buick Trucks Enclave, confirm that all four tires are the correct size for the wheel package and are in sound condition. Pressure, tread condition, sidewall health, and any sign of cuts, bulges, or persistent air loss deserve attention before the vehicle is asked to spend extended time at highway speeds.
A longer trip is also a good reason to verify that the Enclave's wheel and tire setup is consistent from corner to corner, especially on a used vehicle that may have had replacements over time. Looking over alignment wear, checking the spare situation, and making sure the wheels match the intended diameter can prevent avoidable road-use problems.
