The 2008 Buick Trucks Enclave arrived as a more polished, carlike take on the three-row crossover, blending family-vehicle practicality with Buick’s upscale comfort focus. For buyers keeping one on the road today, tire selection is less about vintage-style construction and more about matching the correct wheel package the vehicle came with. The 2008 Buick Trucks Enclave uses radial tires in two sizes, 255/65R18 and 255/60R19, depending on sub-model. That means the key decision is confirming whether the vehicle has the 18-inch or 19-inch setup first, then comparing tire choices that suit the Enclave’s appearance, road manners, and everyday use.
Which Tire Size Is Right for The 2008 Buick Trucks Enclave
The 2008 Buick Trucks Enclave uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. Both are radial metric sizes, but one fits an 18-inch rim and the other fits a 19-inch rim, so confirming the actual wheel setup is the first step before comparing replacement tires.
255/65R18 is a metric radial size in which 255 identifies the tire’s nominal section width in millimeters, 65 is the aspect ratio, R marks radial construction, and 18 is the rim diameter in inches. On the 2008 Buick Trucks Enclave, this size supports the factory-style 18-inch wheel setup used on the CX. For a buyer, the important point is preserving the correct 18-inch fitment while choosing a tire that matches the Enclave’s intended ride, load needs, and overall vehicle setup.
255/60R19 is a metric radial size with a 255-millimeter nominal section width, a 60-series profile, radial construction, and a 19-inch rim diameter. On the 2008 Buick Trucks Enclave, this size belongs to the 19-inch wheel package used on the CXL. Its dimensions closely reflect the larger-wheel fitment for this model, so the buyer’s job is to confirm the Enclave still has the correct 19-inch wheels and enough clearance if any wheel, suspension, or ride-height changes have been made.
Sub-model fitment matters on the 2008 Buick Trucks Enclave because tire size changes with the wheel package. Checking whether the vehicle is a CX or CXL is the quickest way to narrow the correct size before selecting a replacement tire.

2008 Buick Trucks Enclave CX
The 2008 Buick Trucks Enclave CX uses the 255/65R18 radial tire size on an 18-inch wheel package. That makes tire selection fairly straightforward, as long as the vehicle still carries its correct wheel diameter and has not been changed to a different wheel setup.
The 2008 Buick Trucks Enclave CXL uses the 255/60R19 radial tire size on a 19-inch wheel package. Tire choice starts with confirming that 19-inch rim diameter, then comparing replacement options that suit the vehicle’s road use and any changes made since new.
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 focus on the two tire sizes used on the 2008 Buick Trucks Enclave, the difference between CX and CXL fitment, wheel-diameter checks, and practical inspection points before putting the vehicle back into regular road use.
Tire Size & Fitment
What tire size fits a 2008 Buick Trucks Enclave?
The 2008 Buick Trucks Enclave uses two tire sizes: 255/65R18 and 255/60R19. Both are radial metric sizes, and the correct one depends on the vehicle’s sub-model and wheel package rather than being interchangeable across every Enclave without verification.
CX models use 255/65R18, while CXL models use 255/60R19. Since those sizes fit different rim diameters, the safest starting point is to confirm the Enclave’s actual wheel size before choosing tires, especially if the vehicle has had aftermarket wheels, a trim swap, or any previous replacement that changed the original setup.
What size rim does a 2008 Buick Trucks Enclave use?
A 2008 Buick Trucks Enclave uses either an 18-inch or 19-inch rim, depending on sub-model. The 255/65R18 tire is built for an 18-inch wheel, and the 255/60R19 tire is built for a 19-inch wheel.
That rim diameter difference is the key fitment checkpoint on this vehicle. Before replacing tires, check the wheel itself and the tire sidewall already mounted on the Enclave so the new tire matches the actual rim diameter, not just the model year and nameplate.
Do all 2008 Buick Trucks Enclave sub-models use the same tire size?
No. The 2008 Buick Trucks Enclave does not use one tire size across all covered sub-models. The CX uses 255/65R18, while the CXL uses 255/60R19, and both are radial tires.
That means the tire decision starts with identifying the exact sub-model or, even better, confirming the wheel diameter currently on the vehicle. Two Enclaves from the same year can require different tires, so selecting by sub-model alone is helpful, but checking the wheel and existing size marking is even better.
Choosing the Right Tire
What should I consider when choosing a 255/65R18 tire for a 2008 Buick Trucks Enclave?
Start by confirming that the Enclave is using the 18-inch setup intended for the 255/65R18 size. This is the correct radial size for the 2008 Buick Trucks Enclave CX, so the main goal is matching the tire to the proper wheel package and the vehicle’s intended use.
Beyond size, consider how the Enclave is driven and whether the wheel setup is still original. A family-use crossover that sees regular road miles may need a different replacement emphasis than one driven only occasionally, but the tire still needs to match the 18-inch rim and clear the vehicle properly.
What should I consider when choosing a 255/60R19 tire for a 2008 Buick Trucks Enclave?
The first step is verifying that the vehicle has the 19-inch wheel package used with 255/60R19. On the 2008 Buick Trucks Enclave, that size belongs to the CXL, and it should be selected as a radial tire matched to the correct rim diameter.
A buyer should also look at the Enclave’s current condition and any wheel or suspension changes made over time. Even when the size is correct on paper, clearance, wheel width, and general vehicle setup still matter, particularly on a crossover that may have seen years of tire replacements or aftermarket changes.
How do I choose between the available 2008 Buick Trucks Enclave tire sizes?
You do not choose between 255/65R18 and 255/60R19 based on preference alone. The correct size is determined by the Enclave’s wheel diameter and sub-model, with CX using 255/65R18 and CXL using 255/60R19.
The practical approach is to confirm the actual wheel size on the vehicle first, then replace the tire with the matching size. Even though both sizes share similar overall dimensions, they are built for different rim diameters, so choosing the right one depends on the wheel the tire has to mount on.
Restoration & Appearance
Does correct tire fitment matter for a 2008 Buick Trucks Enclave restoration?
Yes. Even on a newer collector-interest vehicle or clean original-driver example, correct tire fitment matters because the 2008 Buick Trucks Enclave used different sizes for different wheel packages. Keeping the proper size helps preserve the vehicle’s intended stance, wheel relationship, and overall presentation.
A restoration-minded owner should first verify whether the Enclave is a CX with 255/65R18 tires or a CXL with 255/60R19 tires. If originality matters, compare the current wheel and tire setup against the vehicle’s actual configuration rather than assuming every 2008 Enclave used the same package.
How does tire construction affect the appearance of a restored 2008 Buick Trucks Enclave?
On a 2008 Buick Trucks Enclave, construction is straightforward because the primary fitments are radial tires. That means appearance differences are less about choosing between bias-ply and radial and more about keeping the correct modern metric size matched to the right wheel diameter.
For a clean, original-style presentation, the visual priority is usually preserving the proper 18-inch or 19-inch wheel-and-tire proportion for the sub-model. A tire that matches the intended size tends to look more at home on the vehicle than one chosen only by convenience or because it happened to be available.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Buick Trucks Enclave?
Yes. Modifications can change tire fitment on a 2008 Buick Trucks Enclave even when the vehicle started with the correct CX or CXL tire size. Aftermarket wheels, altered wheel width, suspension changes, or ride-height changes can all affect how a tire fits and clears the vehicle.
A changed setup should be checked carefully before replacement tires are chosen. Wheel diameter is only the first piece of the puzzle; wheel width, offset, steering clearance, and fender space also matter, especially if the Enclave no longer carries the same wheel package it used when new.
What should I inspect before driving a 2008 Buick Trucks Enclave on new tires?
Check the wheel diameter, confirm the tire size matches the vehicle’s setup, and inspect the wheels for damage before mounting new tires. It is also smart to look over tread clearance areas, suspension condition, and the general state of the steering and braking systems.
Once the tires are installed, verify inflation pressure, look for any sign of rubbing at full steering lock, and pay attention to vibration or pull on the first drive. An older crossover can have worn suspension parts or alignment issues that show up quickly after fresh tires are fitted.
How often should tires on a 2008 Buick Trucks Enclave be inspected?
Tires on a 2008 Buick Trucks Enclave should be inspected regularly, not just when tread looks worn. Check them for uneven wear, cracking, cuts, bulges, and slow air loss, especially if the vehicle sits for long periods or sees only occasional use.
A quick visual check before routine driving is useful, and a closer inspection before longer trips is even better. Paying attention to condition matters as much as checking size, because even correctly fitted 255/65R18 or 255/60R19 tires need to be in sound shape to support safe road use.
