The 2016 Buick LaCrosse sits in the modern full-size Buick tradition, blending quiet highway comfort with a more tailored, upscale look than many mainstream sedans of its era. For owners, tire selection is less about vintage construction and more about matching the exact wheel and trim setup on the car. This LaCrosse uses radial tires, but fitment spans four sizes: 225/55R17, 235/50R18, 245/45R19, and 245/40R20. Available choices range from blackwall performance-oriented tires to redline, raised white letter, and wide whitewall styles in select sizes. The key is confirming the exact sub-model and rim diameter before choosing a tire that suits the car's appearance and road use.
Which Tire Size Is Right for The 2016 Buick LaCrosse
The 2016 Buick LaCrosse uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. These are all radial fitments, but they span 17-inch, 18-inch, 19-inch, and 20-inch rims. Before selecting a tire, confirm which LaCrosse trim and wheel package is on the car, since several sub-models were offered with more than one factory-size combination.
225/55R17 is a metric radial size with a 225 millimeter section width, a 55-series aspect ratio, and fitment for a 17-inch rim. On the 2016 Buick LaCrosse, this size serves specific 2.4L configurations rather than the full model range. Available choices include BFGoodrich options in blackwall, wide whitewall, and redline form across g-Force and Silvertown Radial series. This size makes the most sense when the car retains its 17-inch wheel setup and the owner wants to balance correct fitment with either a contemporary or more appearance-driven tire style.
Fit(s): 2.4L, 3.6L, Leather 2.4L, Leather 3.6L, Premium, and Sport Touring
Construction: Radial|Rim: 18 in
235/50R18 is a metric radial size that pairs a 235 millimeter section width with a 50-series profile on an 18-inch rim. It is the most widely shared size across the 2016 Buick LaCrosse range, appearing on several 2.4L, 3.6L, Leather, Premium, and Sport Touring versions. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter sidewall treatments depending on the tire series. This is an important size to verify carefully on cars that may have changed wheels, since some LaCrosse trims were also fitted with 17-inch, 19-inch, or 20-inch packages.
Fit(s): Leather 3.6L, Leather 3.6L (AWD), and Premium
Construction: Radial|Rim: 19 in
245/45R19 is a metric radial size with a 245 millimeter section width, a 45-series profile, and a 19-inch rim requirement. On the 2016 Buick LaCrosse, it is tied to select Leather 3.6L and Premium applications rather than every configuration. Available tires in this size come from BFGoodrich and Nitto, with blackwall styling across g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. This size deserves close attention if the car is a Premium or Leather 3.6L model, because moving to or from a 19-inch setup also means confirming the actual wheel diameter already on the vehicle.
245/40R20 is a metric radial size that uses a 245 millimeter section width, a lower 40-series profile, and a 20-inch rim. For the 2016 Buick LaCrosse, this size is associated with certain Premium applications and reflects the need to match the larger wheel package exactly. Tire choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter presentations available depending on the series. This size is best approached by first confirming that the car still wears its 20-inch wheels, since it is not interchangeable with the smaller-diameter LaCrosse fitments without a wheel change.
Tire fitment for the 2016 Buick LaCrosse varies meaningfully by sub-model, and several versions were offered with more than one wheel-and-tire combination. Checking the exact engine, trim, and whether the car is AWD is the first step before narrowing the choice to the correct size and tire style.

2016 Buick LaCrosse 2.4L
The 2016 Buick LaCrosse 2.4L uses either a 225/55R17 or 235/50R18 radial, depending on the wheel setup on the car. That makes wheel-diameter confirmation essential before choosing between the available blackwall or appearance-oriented options in the correct size.
The 2016 Buick LaCrosse 3.6L uses the 235/50R18 radial size. With the size settled, the decision shifts to brand, tire series, and whether a straightforward blackwall presentation is the right match for the car.
The 2016 Buick LaCrosse Leather 2.4L can use either 225/55R17 or 235/50R18 radials, so the exact wheel package matters. Once the rim diameter is confirmed, tire selection becomes a matter of choosing the preferred series and sidewall treatment within that fitment.
The 2016 Buick LaCrosse Leather 3.6L was fitted with either 235/50R18 or 245/45R19 radial tires. That means the owner should verify the actual wheel size on the car before comparing available blackwall performance-oriented choices in the correct diameter.
The 2016 Buick LaCrosse Leather 3.6L (AWD) uses the 245/45R19 radial size. Tire choice then centers on selecting among the available blackwall series while keeping the existing 19-inch wheel setup and overall vehicle presentation in mind.

Tire Size & Fitment
What tire size fits a 2016 Buick LaCrosse?
The 2016 Buick LaCrosse uses four primary tire sizes: 225/55R17, 235/50R18, 245/45R19, and 245/40R20. All four are radial sizes, but they do not apply across every version of the car. Some trims use one size, while others were available with more than one wheel-and-tire package.
The practical step is to match the tire to the exact sub-model and the wheel diameter currently on the vehicle. A LaCrosse that uses a 17-inch or 18-inch setup cannot simply be treated the same as one running 19-inch or 20-inch wheels, so the trim and rim size should be confirmed before comparing brands or sidewall styles.
What size rim does a 2016 Buick LaCrosse use?
A 2016 Buick LaCrosse may use 17-inch, 18-inch, 19-inch, or 20-inch rims, depending on the sub-model and wheel package. Those rim diameters correspond to the four primary tire sizes used on the car: 225/55R17, 235/50R18, 245/45R19, and 245/40R20.
Rim diameter is the first thing to verify because it immediately narrows the correct tire size. Looking only at the trim name is not always enough, since some LaCrosse versions were offered with more than one factory-size combination. Checking the wheel itself, the existing tire sidewall, and the exact sub-model helps prevent choosing the wrong diameter.
Why does the 2016 Buick LaCrosse have more than one tire size?
The 2016 Buick LaCrosse has more than one tire size because different trims and wheel packages used different rim diameters. Fitment ranges from 17-inch through 20-inch wheels, with certain sub-models sharing one size and others offering two or even three possible size combinations.
That variation means tire selection starts with the exact configuration on the car rather than the model name alone. Premium models, for example, can span several diameters, while some other versions use only one. Confirming the installed wheel size keeps the search focused and helps the owner compare only the tires that belong on that setup.
Choosing the Right Tire
What should I consider when choosing a 2016 Buick LaCrosse tire?
Start with the exact tire size and rim diameter used on the car, since the 2016 Buick LaCrosse spans four different radial fitments. After size is confirmed, compare construction details such as rim-width compatibility where stated, plus load figures, tire series, and the intended character of the tire.
Appearance also plays a role because some sizes are available only in blackwall form, while others include redline, raised white letter, or wide whitewall choices. A daily-driven LaCrosse and one being styled for a more customized presentation may call for different priorities, but the tire still needs to match the actual wheel and vehicle setup.
What sidewall styles are available for 2016 Buick LaCrosse tires?
Sidewall choices for the 2016 Buick LaCrosse include blackwall across all four primary sizes, with additional appearance options in select fitments. Depending on size, redline, raised white letter, and wide whitewall tires are also available. The broader appearance selection is concentrated in the 17-inch, 18-inch, and 20-inch fitments.
That means sidewall style should be chosen after the size is settled, not before. A buyer looking for a traditional blackwall presentation has options in every size, while someone wanting a stronger visual statement needs to work within the sidewall treatments offered for that specific diameter. The right choice depends on both fitment and the look desired.
What brands offer tires for the 2016 Buick LaCrosse?
Tires for the 2016 Buick LaCrosse are available from BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears across the full fitment range, while Nitto and Pro-Trac are concentrated in certain 18-inch, 19-inch, and 20-inch applications. Brand availability changes with the exact tire size on the car.
The useful comparison is not simply brand against brand, but how each option is configured within the correct size. One tire may be offered only as a blackwall performance-style radial, while another adds redline or raised white letter styling. Matching the brand to the tire size, series, and intended appearance usually leads to the clearest decision.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Buick LaCrosse?
A period-style approach for a 2016 Buick LaCrosse starts with retaining the exact tire size and wheel diameter used by the car, then choosing a radial that supports the look you want. Depending on size, options range from straightforward blackwall tires to Silvertown Radial, Street Pro III, redline, raised white letter, or wide whitewall presentations.
The most convincing result usually comes from balancing visual style with the wheel package already on the vehicle. A 17-inch LaCrosse can support a different appearance than a 20-inch setup, so sidewall treatment should complement the trim and stance of the car. Exact originality claims are best checked against vehicle-specific Buick references when that level of detail matters.
How does tire construction affect the appearance of a restored 2016 Buick LaCrosse?
On a 2016 Buick LaCrosse, construction is straightforward because the primary fitments are radial across all sizes. That means the visual difference comes less from bias-ply versus radial choice and more from sidewall treatment, tire series, and the overall proportion created by the car's 17-inch through 20-inch wheel packages.
For appearance-focused owners, the main decision is whether the car should wear a clean blackwall, a redline, a raised white letter tire, or in some 17-inch cases a wide whitewall. Each gives the LaCrosse a different personality without changing the basic radial construction. Keeping the correct size for the wheel is what preserves the car's intended visual balance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Buick LaCrosse?
Yes, modifications can affect tire fitment on a 2016 Buick LaCrosse. Aftermarket wheels, suspension changes, lowering, or prior wheel-package swaps can all change whether the original 17-inch, 18-inch, 19-inch, or 20-inch size is still the right starting point for the car.
A modified LaCrosse should be checked for actual wheel diameter and width, plus clearance at the fenders and through the steering range before a new tire is chosen. Even when the size on the sidewall looks familiar, the overall setup may no longer match the original trim fitment. That is especially important on Premium cars that could already span multiple factory diameters.
What should I inspect before driving a 2016 Buick LaCrosse on new tires?
Before driving a 2016 Buick LaCrosse on new tires, inspect wheel condition, confirm the tire size matches the car's actual rim diameter, and make sure inflation is set appropriately for the installation. It also helps to check for any visible interference around the inner fender, suspension, and steering components once the tires are mounted.
Road readiness also depends on the rest of the car. Uneven wear, vibration, or pulling can point to alignment or suspension issues that a new set of tires will not solve by itself. A short test drive followed by a second look for rubbing, air loss, or abnormal contact patterns is a sensible final check before regular use.
How often should tires on a 2016 Buick LaCrosse be inspected?
Tires on a 2016 Buick LaCrosse should be inspected regularly, especially if the car is driven infrequently or stored for long periods. A quick routine check for tread wear, cuts, cracking, bulges, and air loss helps catch age- or use-related issues before they become more serious.
Inspection matters just as much on a low-mileage car as it does on a daily driver, since time and storage conditions can affect tire condition even when tread still looks good. Pressure should be checked periodically, and any change in ride quality, noise, or steering feel deserves attention. On a car with optional wheel packages, keeping all four tires matched correctly is also important.
