The 2010 Buick Trucks Enclave arrived as a car-based crossover with a strong emphasis on quiet highway comfort, family space, and a more upscale driving feel than many traditional SUVs. That character makes tire choice especially important, because the right size helps preserve the Enclave’s balanced ride and road manners. This model uses radial tires in two primary sizes, 255/60R19 and 255/55R20, depending on configuration and wheel setup. The decision here is less about vintage construction and more about confirming the correct rim diameter, then choosing the proper fit for everyday road use, replacement planning, and the vehicle’s current wheel package.
Which Tire Size Is Right for The 2010 Buick Trucks Enclave
The 2010 Buick Trucks Enclave uses two primary tire sizes, and the first step is confirming which wheel diameter is on the vehicle. Both sizes are radial and closely matched in overall height, but one fits a 19-inch rim and the other fits a 20-inch rim. That means tire selection starts with wheel verification, then moves to the correct size for the exact Enclave configuration.
255/60R19 is a metric radial size in which 255 indicates section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. On the 2010 Buick Trucks Enclave, this size supports the vehicle’s crossover-style mix of ride comfort and road-going stability on a 19-inch wheel. It is used on the Enclave CX and also appears on some Enclave CXL configurations. This is the size to evaluate when the vehicle retains its 19-inch wheel setup and you want to stay with the intended fitment range.
255/55R20 is a metric radial size with the same 255-millimeter nominal width as the 19-inch option, but a lower 55-series profile and a 20-inch rim diameter. For the 2010 Buick Trucks Enclave, this size applies to certain CXL configurations equipped with 20-inch wheels. Its closely matched overall diameter keeps it in the same general fitment family while matching a different wheel package. This is the size to use only after confirming that the vehicle actually has the 20-inch rim setup rather than the 19-inch alternative.
Sub-model fitment matters on the 2010 Buick Trucks Enclave because tire size is not the same across every version. The CX stays straightforward, while the CXL can use either of the two radial sizes depending on the wheel package on the vehicle.

2010 Buick Trucks Enclave CX
The 2010 Buick Trucks Enclave CX uses the 255/60R19 radial tire size. Tire selection for the CX starts with staying on the 19-inch wheel package and then choosing a replacement that matches the vehicle’s intended size and road-use needs.
The 2010 Buick Trucks Enclave CXL can use either 255/60R19 or 255/55R20, so wheel confirmation is essential before choosing a tire. That makes the CXL a size-verification decision first, especially if the vehicle has changed hands or its wheels may have been replaced.
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
Common 2010 Buick Trucks Enclave tire questions center on choosing between 255/60R19 and 255/55R20, confirming the right rim size, and checking how wheel changes or replacement decisions affect fitment, ride, and road use.
Tire Size & Fitment
What tire size fits a 2010 Buick Trucks Enclave?
The 2010 Buick Trucks Enclave uses two primary tire sizes: 255/60R19 and 255/55R20. Both are radial sizes, but they do not fit the same wheel diameter. The CX uses 255/60R19, while the CXL may use either 255/60R19 or 255/55R20 depending on the wheel setup.
The practical difference is the rim size, not just the numbers on the sidewall. A 19-inch tire must be matched to a 19-inch wheel, and a 20-inch tire must be matched to a 20-inch wheel. Checking the current wheel diameter on the vehicle is the quickest way to avoid ordering the wrong size, especially on a CXL.
What size rim does a 2010 Buick Trucks Enclave use?
A 2010 Buick Trucks Enclave uses either a 19-inch or 20-inch rim, depending on tire size. The 255/60R19 tire fits a 19-inch rim, and the 255/55R20 tire fits a 20-inch rim. Both sizes are part of the Enclave’s original fitment range for this model year.
Rim diameter should be confirmed before any other tire decision, because the two Enclave sizes are tied directly to different wheels. Looking only at the tire’s width is not enough. If the vehicle has aftermarket wheels, verify the wheel markings and current mounted size so the replacement tire matches the actual rim on the vehicle.
Do all 2010 Buick Trucks Enclave sub-models use the same tire size?
No. The 2010 Buick Trucks Enclave CX uses 255/60R19, but the CXL can use either 255/60R19 or 255/55R20. That means tire fitment is not uniform across all covered Enclave sub-models, even though both available sizes are radial and very close in overall height.
That difference makes sub-model and wheel verification more important than relying on the model name alone. A CX is straightforward, but a CXL needs a closer look at the actual wheel package on the vehicle. The safest approach is to confirm the sidewall size already installed and match it to the wheel diameter before selecting replacements.
Choosing the Right Tire
What should I consider when choosing a 255/60R19 tire for a 2010 Buick Trucks Enclave?
Start by confirming that the Enclave actually uses the 255/60R19 size, since this fitment belongs on a 19-inch wheel. On the 2010 Buick Trucks Enclave, it is the CX size and also appears on some CXL models. Choosing within that size is mainly about maintaining the proper fitment rather than changing dimensions.
A good replacement decision also involves checking the vehicle’s present wheel setup, overall tire condition, and how the Enclave is used. Daily road use, occasional highway travel, and any prior wheel changes all matter. Matching the installed size keeps the fitment straightforward and helps preserve the ride and clearance relationship intended for the 19-inch package.
What should I consider when choosing a 255/55R20 tire for a 2010 Buick Trucks Enclave?
The first requirement is confirming that the vehicle has the 20-inch wheel package, because 255/55R20 is tied to that rim diameter. On the 2010 Buick Trucks Enclave, this size applies to certain CXL configurations. It is not a universal size across every Enclave sub-model in this model year.
Once wheel diameter is confirmed, the focus shifts to keeping the replacement within the proper size for the vehicle’s existing setup. It also helps to inspect wheel condition, current clearance, and any signs that the suspension or alignment needs attention. A 20-inch fitment should be selected as a match for the wheel package already on the vehicle, not as a casual substitute.
How do I choose between the available 2010 Buick Trucks Enclave tire sizes?
The choice between 255/60R19 and 255/55R20 is determined by the wheel diameter on the vehicle. A 2010 Buick Trucks Enclave with 19-inch wheels uses 255/60R19, while one with 20-inch wheels uses 255/55R20. The sizes are both radial, but they are not interchangeable across different rim diameters.
For most owners, the right path is to match the installed wheel package instead of trying to select between sizes as a preference. The tire sidewall and the wheel itself should agree on diameter. On a CXL, that check is especially important because both factory fitment paths exist, and the correct replacement depends on the actual setup in front of you.
Restoration & Appearance
Does correct tire fitment matter for a 2010 Buick Trucks Enclave restoration or preservation project?
Yes. Even on a newer collector-era SUV crossover, correct tire fitment still matters because it affects stance, wheel compatibility, and the way the vehicle presents itself. The 2010 Buick Trucks Enclave belongs with either 255/60R19 or 255/55R20, depending on the wheel package and sub-model configuration.
Preservation-minded owners usually benefit from keeping the proper size tied to the vehicle’s actual wheel setup instead of mixing diameters or guessing from another trim level. A careful fitment choice helps the Enclave retain a cohesive appearance and avoids unnecessary clearance issues. When originality matters closely, compare the vehicle’s present wheels to period Buick reference material.
Which tire should I choose for a period-style 2010 Buick Trucks Enclave?
A period-style choice for a 2010 Buick Trucks Enclave starts with the correct original fitment family for the vehicle’s wheel diameter. That means 255/60R19 on the 19-inch setup or 255/55R20 on the 20-inch setup. Because this Enclave uses modern radial sizes, the main appearance decision is preserving the correct overall visual proportion.
Keeping the proper size on the proper wheel usually does more for a clean, era-appropriate presentation than experimenting with alternate diameters. Owners focused on preservation should also confirm that the wheels themselves match the intended configuration for the vehicle. Staying within the correct size range helps the Enclave look settled and consistent rather than altered.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Buick Trucks Enclave?
Yes. A 2010 Buick Trucks Enclave may have fitment changes if it has aftermarket wheels, suspension alterations, or body modifications. Even though the original tire sizes are 255/60R19 and 255/55R20, changes in wheel diameter, width, or offset can affect how a replacement tire sits and clears surrounding components.
That is why the current vehicle setup matters more than assumptions based on trim alone. Check the actual wheel diameter, inspect for altered ride height, and look for signs of rubbing near the fenders and steering components. A replacement tire should match both the intended size and the Enclave’s present wheel-and-suspension configuration before road use.
What should I inspect before driving a 2010 Buick Trucks Enclave on new tires?
Before driving, confirm that the new tires match the Enclave’s wheel diameter and installed size, then inspect for proper mounting and inflation. The vehicle should also be checked for obvious suspension wear, damaged wheels, and any signs of previous tire rubbing. Those basic checks matter whether the Enclave uses 255/60R19 or 255/55R20.
A short visual inspection can prevent bigger problems on the road. Look at sidewall seating around the rim, check for air loss after installation, and turn the steering through its range to watch for clearance concerns. It also helps to monitor how the Enclave tracks and rides on its first drive, since vibration or pull can signal a setup issue.
How often should tires on a 2010 Buick Trucks Enclave be inspected?
Tires on a 2010 Buick Trucks Enclave should be inspected regularly, not just when tread looks low. Collector-owned or lightly used vehicles deserve the same attention, because age, air loss, and sidewall condition can matter as much as mileage. Routine visual checks help catch cracking, cuts, bulges, and uneven wear before they become road-use concerns.
A smart habit is to inspect the tires before longer drives and any time the Enclave has been sitting for an extended period. Check inflation, look for flat spotting, and confirm that tread wear remains even across the tire. Regular inspection is especially useful on older vehicles that may see seasonal use rather than constant daily miles.
