The 2009 Buick LaCrosse sits in the final years of Buick’s first-generation midsize sedan, blending traditional comfort with a more contemporary range of wheel and tire packages than many buyers expect. It appeals to owners who want either a clean stock-style replacement or a more appearance-conscious update without stepping away from the car’s intended character. Tire fitment spans three primary radial sizes: 225/60R16, 225/55R17, and 235/50R18, depending on sub-model and wheel setup. That creates meaningful choices in sidewall style, tire series, and overall presentation. The key is matching the tire to the exact trim and wheel diameter already on the car before comparing brands or styling details.
Which Tire Size Is Right for The 2009 Buick LaCrosse
Three primary tire sizes apply to the 2009 Buick LaCrosse, and the right one depends first on the exact sub-model and wheel diameter. The car uses radial construction throughout, but fitment ranges from 16-inch to 18-inch rims, so identifying whether the car is a CX, CXL, or Super is the first step before comparing tread style, sidewall treatment, or tire series.
In 225/60R16, the 225 identifies the tire’s nominal section width in millimeters, the 60 is the aspect ratio, the R indicates radial construction, and the 16 is the wheel diameter in inches. On the 2009 Buick LaCrosse, this size suits the car’s more comfort-oriented fitment and appears on 16-inch wheel applications. Available choices include BFGoodrich, Goodyear, and Travelstar options, with sidewall treatments such as raised yellow letter, redline, pin white stripe, wide whitewall, and narrow whitewall. It is the size to evaluate when the car retains its 16-inch wheel package and appearance preference matters as much as basic fitment.
A 225/55R17 tire uses the same 225-millimeter nominal width as the 16-inch size, but the 55-series profile is paired with a 17-inch rim. This is still a radial fitment, but it belongs to a different wheel package on the 2009 Buick LaCrosse and should not be chosen until the 17-inch wheel setup is confirmed. Product choices lean toward either performance-style blackwall tires or more traditional BFGoodrich Silvertown Radial options with wide whitewall or redline sidewalls. This size is worth considering when the car is equipped with the 17-inch package and the goal is to balance correct dimensions with the right visual character.
The 235/50R18 size is wider than the 225-millimeter options and is built around an 18-inch rim, with the 50-series profile helping define the overall package. For the 2009 Buick LaCrosse, this radial size is tied to the largest wheel application in the range and should be matched carefully to the car’s exact trim and wheel setup. Available tires include BFGoodrich, Nitto, and Pro-Trac selections, with blackwall, redline, and raised white letter sidewall presentations depending on the series. It is the size to focus on when the car already carries its 18-inch configuration and the buyer wants to compare both performance-oriented and styling-driven choices.
Sub-model fitment matters on the 2009 Buick LaCrosse because tire size changes across the lineup. The CX, CXL, and Super do not all use the same wheel diameter, so confirming the exact trim is the easiest way to avoid choosing the wrong tire before comparing brands or sidewall styles.

2009 Buick LaCrosse CX
The 2009 Buick LaCrosse CX uses the 225/60R16 radial fitment on a 16-inch wheel package. Tire selection here is less about sorting through multiple primary sizes and more about choosing the right sidewall look, tire series, and rim compatibility within that established setup.
The 2009 Buick LaCrosse CXL can use either a 225/60R16 or a 225/55R17 radial tire, depending on the wheel package on the car. That makes wheel-diameter confirmation especially important before selecting a replacement, since appearance options and tire families differ between the 16-inch and 17-inch fitments.
The 2009 Buick LaCrosse Super uses the 235/50R18 radial size on an 18-inch wheel package. Tire choice for the Super centers on staying with the correct larger-wheel fitment while comparing blackwall, redline, or raised white letter styling and the available performance-oriented series.
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.

These FAQs focus on the 2009 Buick LaCrosse tire questions that matter most: identifying the right size by sub-model, confirming wheel diameter, comparing available radial choices, and checking fitment, appearance, and road-use details before installation.
Tire Size & Fitment
What tire size fits a 2009 Buick LaCrosse?
A 2009 Buick LaCrosse uses one of three radial tire sizes: 225/60R16, 225/55R17, or 235/50R18. The correct size depends on the sub-model and wheel package. The CX uses 225/60R16, the Super uses 235/50R18, and the CXL can use either 225/60R16 or 225/55R17.
That means the first step is confirming the trim and the actual wheel diameter already on the car. A CXL owner in particular should not assume one size over the other without checking the wheels, since both 16-inch and 17-inch fitments exist. Once the correct size is confirmed, the decision shifts to tire series, sidewall style, and rim-width compatibility within that size.
What size rim does a 2009 Buick LaCrosse use?
The 2009 Buick LaCrosse uses three different rim diameters across its tire fitments: 16-inch, 17-inch, and 18-inch. Those correspond to 225/60R16, 225/55R17, and 235/50R18 tire sizes. Rim diameter is tied directly to the tire size, so the tire must match the wheel already on the car.
Checking the wheel is especially important on used cars, since trim-based fitment can blur after wheel changes or replacement packages over time. The tire size molded into the current sidewall can be a useful clue, but the wheel itself should still be verified before ordering. Diameter comes first, then width and intended style can be compared within the correct size range.
Do all 2009 Buick LaCrosse sub-models use the same tire size?
No, the 2009 Buick LaCrosse sub-models do not all use the same tire size. The CX uses 225/60R16, the Super uses 235/50R18, and the CXL can use either 225/60R16 or 225/55R17. All of them use radial construction, but the wheel diameter and size combination changes across the lineup.
That variation matters because a tire that matches one LaCrosse trim may be wrong for another simply due to wheel diameter. The CXL deserves extra attention because it appears with two different primary sizes. Verifying the exact sub-model and measuring the wheel before comparing sidewall treatments or brand options is the safest way to narrow the search.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 Buick LaCrosse?
Start with the correct size for the car’s trim and wheel diameter, since the 2009 Buick LaCrosse uses 225/60R16, 225/55R17, or 235/50R18 depending on configuration. From there, compare radial construction details such as rim-width suitability, load figures where shown, tire series, and whether the car needs a more traditional or more performance-oriented visual presentation.
The right choice depends on how the car is actually used and how closely the owner wants to stay with its existing look. A LaCrosse with 16-inch wheels may invite whitewall or stripe styling, while 17-inch and 18-inch fitments include more blackwall performance-style options. Wheel condition, suspension condition, and any prior modifications should also be checked before final selection.
What sidewall styles are available for 2009 Buick LaCrosse tires?
Sidewall choices for the 2009 Buick LaCrosse vary by tire size and series. Available styles include blackwall, redline, raised yellow letter, raised white letter, pin white stripe, wide whitewall, and narrow whitewall. The broader visual range appears mainly in the 16-inch and 18-inch fitments, while the 17-inch size mixes blackwall with traditional whitewall and redline options.
That variety lets the tire influence the car’s overall presentation more than many modern sedan owners expect. A cleaner stock-style look may point toward blackwall, while a more nostalgic appearance may favor whitewall, pin stripe, or redline treatments. The sidewall should be chosen only after the correct tire size is confirmed, since not every style is offered in every LaCrosse fitment.
What brands offer tires for the 2009 Buick LaCrosse?
Tires for the 2009 Buick LaCrosse are available from BFGoodrich, Goodyear, Travelstar, Nitto, and Pro-Trac, depending on the tire size. BFGoodrich appears across all three primary sizes, while Goodyear and Travelstar are part of the 225/60R16 selection, Nitto appears in 235/50R18, and Pro-Trac also serves the 18-inch fitment.
Brand comparison is most useful after the correct size and wheel diameter have been settled. At that point, the real differences are often series character, sidewall style, rim-width range, and load or weight details where they are stated. Since availability varies by size, a CX, CXL, and Super owner may each see a different mix of brands even within the same model year.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Buick LaCrosse?
A period-style 2009 Buick LaCrosse usually starts with keeping the correct tire size and wheel diameter for the exact trim, then choosing a radial with the visual character you want. Depending on size, that can include BFGoodrich Silvertown Radial options with redline, pin white stripe, or whitewall styling, as well as other appearance-focused choices in the available fitments.
The most convincing look comes from matching the tire’s sidewall treatment to the car’s wheels, color, and overall presentation rather than chasing a generic vintage style. Since this is a modern-era Buick with several wheel packages, exact originality should be checked against vehicle-specific references if that matters. For many owners, a correct-size radial with the right sidewall presence is the practical sweet spot.
How does tire construction affect the appearance of a restored 2009 Buick LaCrosse?
On a 2009 Buick LaCrosse, tire construction does not create a bias-ply-versus-radial decision because the primary fitments are radial throughout. Appearance is shaped more by sidewall treatment and tire series than by construction type itself. In practical terms, the visual difference comes from blackwall, whitewall, stripe, lettered, or redline presentations within the correct radial size.
That gives a restored or carefully preserved LaCrosse owner room to tune the car’s look without departing from the radial format used by the model. A subtle blackwall can keep the car understated, while whitewall or redline options can add a more stylized, era-conscious presentation. The effect will be strongest when the wheel diameter and proportions remain consistent with the car’s actual trim package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Buick LaCrosse?
Yes, modifications can affect tire fitment on a 2009 Buick LaCrosse even when the tire size looks close on paper. Wheel changes, altered wheel width, suspension lowering, replacement springs, or brake and body changes can all influence clearance and how the tire sits in the wheel opening. That matters most because the LaCrosse already uses three different rim diameters across the model range.
A car that has been changed from its original wheel package should be checked carefully before choosing between 16-inch, 17-inch, or 18-inch fitments. Steering clearance, fender clearance, and the relationship between tire size and wheel width should all be reviewed. Even a correct-size tire for the model year may not suit a modified setup without confirming the actual hardware on the car.
What should I inspect before driving a 2009 Buick LaCrosse on new tires?
Before driving a 2009 Buick LaCrosse on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure inflation is set appropriately for the installed tire. It is also worth checking for suspension wear, uneven old-tire wear patterns, and any rubbing marks that may point to alignment or clearance issues.
A short initial road test can reveal vibration, pull, or interference that was not obvious at installation. Lug hardware should be properly secured, and the owner should recheck pressure after the tires have settled into service. On a LaCrosse that has sat for long periods or changed hands recently, that extra review is especially useful before relying on the car for regular road use.
How often should tires on a 2009 Buick LaCrosse be inspected?
Tires on a 2009 Buick LaCrosse should be inspected regularly for pressure loss, tread wear, cuts, bulges, and sidewall aging. A visual check before longer drives is a good habit, and cars that see occasional use deserve even closer attention because low annual mileage can hide age-related deterioration. Uneven wear can also signal alignment or suspension issues rather than a tire problem alone.
Inspection frequency matters because this model can carry several different wheel and tire packages, and each setup should be watched for proper clearance and wear behavior. Pressure should be maintained consistently, and any sudden change in ride quality or steering feel deserves a closer look. Tires on collector-kept or lightly used sedans often age out before they wear out, so condition matters as much as tread depth.
