The 2013 Buick LaCrosse sits in the modern full-size sedan space with Buick’s familiar emphasis on quiet highway comfort, substantial road manners, and upscale everyday use. It is a vehicle where tire choice has a direct effect on ride character, steering response, and overall stance. Tire fitment spans four primary radial sizes on 17-inch, 18-inch, and 19-inch wheels, so the first step is matching the exact sub-model and wheel setup. Available choices range from performance-oriented blackwall radials to 18-inch options with redline or raised white letter styling. For a stock sedan, a restored appearance, or a modified street-driven setup, exact size and wheel confirmation matter before selecting a tire.
Which Tire Size Is Right for The 2013 Buick LaCrosse
The 2013 Buick LaCrosse uses four primary tire sizes, and they are tied to specific sub-model and wheel combinations rather than one universal fitment. Sizes span 17-inch, 18-inch, and 19-inch rims, so the first job is confirming the exact sub-model and actual wheel diameter on the car before comparing tire style, sidewall treatment, or product series.
235/50R17 is a modern metric radial size. The 235 identifies nominal section width in millimeters, the 50 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2013 Buick LaCrosse, this size suits 17-inch wheel applications and keeps the buying decision focused on radial tire design rather than construction changes. Available examples in this size lean toward blackwall performance-style presentation, so it is a strong starting point when the car retains the correct 17-inch wheel setup and stock-type fitment.
235/50R18 follows the same modern metric radial format, with a 235-millimeter nominal section width, a 50-series profile, radial construction, and an 18-inch rim diameter. For the 2013 Buick LaCrosse, this size appears on certain sub-models using 18-inch wheels, making wheel confirmation essential before selection. Product choice is broader here, with BFGoodrich, Nitto, and Pro-Trac offerings, plus blackwall, redline, and raised white letter sidewall treatments. That makes this size especially useful for buyers balancing everyday road use with a more customized or appearance-conscious look.
245/50R17 is another modern metric radial size, but it uses a wider 245-millimeter nominal section width while keeping a 50-series profile and 17-inch wheel diameter. On the 2013 Buick LaCrosse, this size applies to certain configurations rather than every sub-model, so it should be matched carefully to the car’s actual wheel and trim setup. Its dimensions make it a different fitment path than the 235/50R17 even though both mount on 17-inch wheels. This is the size to evaluate when the vehicle already carries the correct wider 17-inch application.
245/40R19 is a modern metric radial with a 245-millimeter nominal section width, a lower 40-series profile, and a 19-inch rim diameter. For the 2013 Buick LaCrosse, it belongs with the 19-inch wheel application and gives the car a distinctly different sizing profile than the 17-inch and 18-inch options. Available products in this size come from BFGoodrich in several g-Force series, all in blackwall form. It is the right fitment path when the car has the correct 19-inch wheel package and the buyer wants to stay with that larger-diameter setup.
Tire fitment for the 2013 Buick LaCrosse varies by sub-model, and some trims use more than one primary size. Checking the exact trim and the wheel diameter currently on the car is the key step before choosing a replacement tire.

2013 Buick LaCrosse Base
The 2013 Buick LaCrosse Base uses a 17-inch radial tire fitment built around 235/50R17. Tire selection here is mainly about choosing the right radial within that size and confirming the car still has its correct 17-inch wheel setup.
The 2013 Buick LaCrosse Leather 2.4L also uses the 235/50R17 radial size. That keeps fitment straightforward, with the main decision centered on selecting a tire style and performance character that matches the car’s intended street use.
The 2013 Buick LaCrosse Leather 3.6L can use either 235/50R18 or 245/50R17, so wheel diameter matters immediately on this trim. Tire selection starts with confirming whether the car is on the 18-inch or 17-inch application before comparing available product options.
The 2013 Buick LaCrosse Premium shares the same two-size fitment pattern, using either 235/50R18 or 245/50R17. That means replacement choice depends on the actual wheel package on the car, not simply the trim badge alone.
The 2013 Buick LaCrosse Touring uses a 19-inch radial fitment built around 245/40R19. Selection is more focused here, with the practical goal being a tire that matches the larger wheel setup and preserves proper clearance and overall fitment.
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.
Best 2013 Buick LaCrosse Tires for Sale
Available 2013 Buick LaCrosse tire choices center on radial performance-oriented products from BFGoodrich, Nitto, and Pro-Trac. Depending on size, buyers can compare blackwall tires across several g-Force series or, in 235/50R18, choose redline or raised white letter styling.
Common 2013 Buick LaCrosse tire questions usually come down to exact size by sub-model, wheel diameter, available radial choices, sidewall style, and what to inspect before putting the car back into regular road use.
Tire Size & Fitment
What tire size fits a 2013 Buick LaCrosse?
The 2013 Buick LaCrosse uses four primary radial tire sizes: 235/50R17, 235/50R18, 245/50R17, and 245/40R19. The correct one depends on the exact sub-model and wheel package, rather than one size fitting every LaCrosse in the lineup.
The practical next step is to confirm the trim level and the actual wheel diameter on the car before ordering tires. A Base or Leather 2.4L points toward 235/50R17, Touring uses 245/40R19, and some Leather 3.6L and Premium cars can fall into either 17-inch or 18-inch fitment paths.
What size rim does a 2013 Buick LaCrosse use?
A 2013 Buick LaCrosse can use 17-inch, 18-inch, or 19-inch rims, depending on the sub-model and tire size. The primary fitments are 235/50R17 and 245/50R17 on 17-inch rims, 235/50R18 on an 18-inch rim, and 245/40R19 on a 19-inch rim.
Rim diameter should be confirmed directly at the car before choosing a replacement tire, especially on Leather 3.6L and Premium models that can use more than one size. Wheel changes made by a previous owner can also alter what fits, so the installed wheel matters more than assumptions based on trim alone.
Why does the 2013 Buick LaCrosse have more than one tire size?
The 2013 Buick LaCrosse has more than one tire size because different sub-models and wheel packages were built around different wheel diameters and tire widths. That is why the fitment range includes 17-inch, 18-inch, and 19-inch applications across the lineup.
This matters because two LaCrosse sedans from the same year may not use the same replacement tire, even if they look similar at a glance. The correct approach is to identify the trim, verify the wheel diameter, and then match the tire size already associated with that configuration before comparing brands or sidewall styles.
Choosing the Right Tire
What should I consider when choosing a 2013 Buick LaCrosse tire?
Start with the exact tire size and wheel diameter used on the car, since the 2013 Buick LaCrosse spans 17-inch, 18-inch, and 19-inch fitments. After that, compare radial construction details such as tire series, intended driving character, sidewall style, and any rim-width guidance tied to the product.
A stock daily-driven sedan may call for a different presentation than a customized car with an appearance focus. It also helps to compare load figures where they are stated, check that the wheel width falls within the tire’s accepted range, and avoid choosing only by tread style or brand name.
What sidewall styles are available for 2013 Buick LaCrosse tires?
Sidewall style depends on tire size. Blackwall options are available across the fitments, while 235/50R18 also opens the door to redline and RWL, or raised white letter, choices through the Pro-Trac Street Pro III line.
That gives 18-inch LaCrosse owners more visual flexibility than the other fitments, which stay more conventional in appearance. A blackwall usually keeps the look understated, while redline or raised white letters can create a more customized presentation, so the right choice depends on whether the car is stock-looking or styled for more visual impact.
What brands offer tires for the 2013 Buick LaCrosse?
Available 2013 Buick LaCrosse tire brands include BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears across multiple fitments, while Nitto and Pro-Trac are part of the 235/50R18 selection.
Brand choice should be weighed alongside the specific tire series, sidewall style, and fitment details for the car’s wheel package. A buyer with 18-inch wheels has the widest range to compare, while 17-inch and 19-inch applications are narrower in selection and should be matched carefully to the exact installed rim diameter.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Buick LaCrosse?
A period-style 2013 Buick LaCrosse tire choice starts with staying in the correct size for the car’s trim and wheel package. Since this is a modern sedan with radial-only primary fitments, the appearance decision is less about bias-ply versus radial and more about sidewall treatment and overall visual character within the right size.
For a cleaner stock-like presentation, blackwall tires are the most natural path across the available fitments. Buyers working with 235/50R18 have more room to shape the look, since that size includes redline and raised white letter options that can push the car toward a more personalized street-oriented appearance.
How does tire construction affect the appearance of a restored 2013 Buick LaCrosse?
On a 2013 Buick LaCrosse, construction does not create a classic bias-ply-versus-radial decision because the primary fitments are radial throughout. The visible appearance difference comes more from sidewall design, tread character, and the proportions created by the correct 17-inch, 18-inch, or 19-inch wheel-and-tire combination.
That means a restoration-minded owner should first preserve the correct size and wheel diameter for the trim, then choose the sidewall style that best suits the car’s intended look. On 18-inch applications, blackwall, redline, and raised white letter choices can all change the visual tone without changing the underlying radial construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Buick LaCrosse?
Yes, modifications can affect tire fitment on a 2013 Buick LaCrosse. Aftermarket wheels, changes in wheel width, altered offset, lowered suspension, or body and brake changes can all influence whether the original 17-inch, 18-inch, or 19-inch tire size still makes sense on the car.
The safest approach is to confirm the actual wheel diameter and width currently installed, then check clearance at the fender, suspension, and steering range before moving to a replacement tire. That is especially important on trims that can use more than one size, where assumptions based only on model name can lead to the wrong choice.
What should I inspect before driving a 2013 Buick LaCrosse on new tires?
Before driving a 2013 Buick LaCrosse on new tires, inspect the wheels for damage, confirm that the new tire size matches the car’s wheel diameter, and make sure the tires are seated and inflated properly. It is also wise to look over valve stems, alignment condition, and visible suspension wear.
A short road test should include listening for rubbing, checking steering feel, and rechecking air pressure after the first miles. Any vibration, pull, or contact under turning or compression deserves attention right away, because the LaCrosse uses several fitment paths and a mismatch in size or wheel setup can show up quickly.
How should tires on a 2013 Buick LaCrosse be maintained?
Tires on a 2013 Buick LaCrosse should be maintained with regular pressure checks, routine visual inspection, and periodic rotation when appropriate for the tire setup. Watch for uneven tread wear, cuts, bulges, cracking, or slow air loss, since even a modern sedan that sees moderate use can age tires before tread is fully worn out.
Storage and use patterns matter as much as mileage. A car that sits for long periods should be kept away from prolonged heat, direct sunlight, and ozone sources, while a car that is driven often benefits from alignment checks and prompt correction of suspension wear that can shorten tire life or disturb ride quality.
