The 2010 Buick Lucerne sits at the end of Buick’s traditional full-size sedan era, blending quiet highway comfort with the kind of upright American luxury many owners still appreciate today. It appeals to buyers who want a later-model Buick with classic proportions and a composed road manner rather than an aggressively sporty character. Tire fitment depends on trim, with most 2010 Buick Lucerne models using 235/55R17 radial tires while the Lucerne Super moves to 245/50R18 radials. That opens the door to different sidewall treatments and tire series, from understated blackwall options to whitewall, goldline, redline, and raised white letter styles. Getting the right size starts with confirming the exact sub-model and wheel setup.
Which Tire Size Is Right for The 2010 Buick Lucerne
The 2010 Buick Lucerne uses two primary tire sizes, and the correct one depends on the sub-model and wheel diameter. Most Lucerne trims use a 17-inch radial tire, while the Lucerne Super uses an 18-inch radial. Before choosing a tire, confirm whether the car is a CX, CXL, CXL Special Edition, or Super, and make sure the wheels still match the original diameter for that trim.
235/55R17 is a modern metric radial size in which 235 identifies the nominal section width in millimeters, 55 is the aspect ratio, R designates radial construction, and 17 is the wheel diameter in inches. On the 2010 Buick Lucerne, this size serves the mainstream trim range and suits the car’s comfort-oriented full-size sedan character. Available choices include blackwall, goldline, wide whitewall, and redline sidewall treatments from brands such as BFGoodrich, American Classic, and Coker Classic. It is the size to evaluate if the car is equipped with 17-inch wheels and the goal is either a contemporary look or a more restoration-inspired presentation.
245/50R18 is also a modern metric radial size, with 245 indicating nominal section width in millimeters, 50 identifying the aspect ratio, and 18 marking the wheel diameter in inches. On the 2010 Buick Lucerne, this size is tied to the Super trim rather than the rest of the Lucerne lineup. Current choices center on Pro-Trac Street Pro III tires with either raised white letter or redline sidewalls, giving the buyer an appearance decision within the correct fitment. This is the size to review when the car has 18-inch wheels and needs the Super model’s proper tire format.
Sub-model fitment matters on the 2010 Buick Lucerne because not every trim uses the same tire size. CX, CXL, and CXL Special Edition share one radial size, while the Super uses a different size on a different wheel diameter, so trim identification should come first.

2010 Buick Lucerne CX
The 2010 Buick Lucerne CX uses the 235/55R17 radial tire size on a 17-inch wheel. Tire selection for the CX is mostly a matter of choosing the right sidewall style, brand, and series while keeping the correct 17-inch fitment in place.
The 2010 Buick Lucerne CXL also uses the 235/55R17 radial tire size. That gives the CXL access to the same range of blackwall and specialty sidewall presentations, so the main decision becomes appearance and product character rather than alternate primary sizes.
The 2010 Buick Lucerne CXL Special Edition uses the same 235/55R17 radial fitment as the other 17-inch Lucerne trims. Choosing a tire here comes down to matching the car’s look and use, whether that means a straightforward blackwall or a more distinctive whitewall, goldline, or redline presentation.
The 2010 Buick Lucerne Super uses 245/50R18 radial tires rather than the 17-inch Lucerne fitment. That makes wheel confirmation especially important, and the available choices focus on sidewall presentation within the correct 18-inch Super size.
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.

Depending on size, buyers can compare blackwall, wide whitewall, goldline, redline, and raised white letter sidewalls along with different tire series and rim-width specifications.
Owners shopping for 2010 Buick Lucerne tires usually need to sort out trim-specific size differences, 17-inch versus 18-inch wheel fitment, sidewall style choices, and practical checks before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2010 Buick Lucerne?
A 2010 Buick Lucerne uses either 235/55R17 or 245/50R18 radial tires, depending on the sub-model. The CX, CXL, and CXL Special Edition use 235/55R17, while the Lucerne Super uses 245/50R18.
The first step is confirming the exact trim and checking the actual wheel diameter on the car. A Lucerne that has been fitted with different wheels over the years may not still match its original trim-based setup, so tire selection should follow the wheel size and vehicle configuration actually in place.
What size rim does a 2010 Buick Lucerne use?
The 2010 Buick Lucerne uses either a 17-inch or 18-inch rim, depending on sub-model. Lucerne CX, CXL, and CXL Special Edition models use a 17-inch rim with 235/55R17 tires, while the Lucerne Super uses an 18-inch rim with 245/50R18 tires.
Rim diameter is the most important fitment check because a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. It also helps to confirm the wheel width and make sure the car still has the proper trim-level wheel package before comparing brands, sidewall styles, or tire series.
Do all 2010 Buick Lucerne sub-models use the same tire size?
No. The 2010 Buick Lucerne has a split fitment by sub-model. CX, CXL, and CXL Special Edition models share the 235/55R17 radial size, while the Lucerne Super uses the larger 245/50R18 radial size.
That difference means the trim name matters before any tire is selected. The tire choice is straightforward once the sub-model and wheel diameter are confirmed, but using the wrong size can create immediate mounting issues or appearance mismatches if the car’s wheels do not correspond to the intended trim-level fitment.
Choosing the Right Tire
What should I consider when choosing a 2010 Buick Lucerne tire?
Start with the correct trim-specific size: 235/55R17 for CX, CXL, and CXL Special Edition models, or 245/50R18 for the Super. From there, compare radial construction details, sidewall style, brand, tire series, and wheel compatibility within the proper size.
A comfort-minded Lucerne owner may prefer a cleaner traditional presentation, while another may want a more customized look through whitewall, goldline, redline, or raised white letter styling. It also helps to compare rim-width specifications and load figures where available so the chosen tire suits both the wheel and the car’s intended road use.
What sidewall styles are available for 2010 Buick Lucerne tires?
Sidewall choices for the 2010 Buick Lucerne vary by tire size. In 235/55R17, available styles include blackwall, goldline, wide whitewall, and redline. In 245/50R18 for the Lucerne Super, available styles include raised white letter and redline.
That variety gives the Lucerne unusual flexibility for appearance, especially for an owner who wants either a subtle late-model look or a more traditional American-car presentation. The right choice still begins with the correct trim and wheel diameter, since sidewall style is only meaningful after the proper primary size has been established.
What brands offer tires for the 2010 Buick Lucerne?
2010 Buick Lucerne tires are available from BFGoodrich, American Classic, Coker Classic, and Pro-Trac, depending on size. The 235/55R17 fitment has the broadest assortment, while the 245/50R18 Lucerne Super fitment is represented by Pro-Trac options.
Brand choice should be weighed alongside the tire series and the appearance you want from the car. Some Lucerne owners will be focused on a straightforward blackwall road tire, while others will be comparing specialty sidewall treatments that better suit a preservation-minded or personalized full-size Buick.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Buick Lucerne?
A period-style 2010 Buick Lucerne tire starts with the correct trim-based size and then moves to appearance. On 235/55R17 Lucernes, American Classic and Coker Classic options bring in wide whitewall, goldline, or redline treatments that can give the car a more traditional American luxury look.
That approach is especially useful for owners who want the Lucerne to feel more connected to Buick’s long sedan heritage rather than simply wearing a modern replacement tire. The key is to stay with the proper size for the sub-model first, then choose a sidewall presentation that complements the car without assuming any one style was factory-original.
How does tire construction affect the appearance of a restored 2010 Buick Lucerne?
On the 2010 Buick Lucerne, the primary fitments are radial tires, so appearance differences come more from sidewall treatment and tire series than from choosing between radial and bias-ply construction. Blackwall, wide whitewall, goldline, redline, and raised white letter styles can each change the car’s visual character noticeably.
A blackwall usually keeps the Lucerne looking closer to a contemporary late-model sedan, while whitewall or goldline choices can lend a more classic Buick flavor. For a restoration-oriented project, the most important step is matching the trim-specific size and wheel diameter first, then selecting the sidewall style that best supports the intended finished look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Buick Lucerne?
Yes. Wheel changes, suspension alterations, lowering, or previous owner modifications can affect tire fitment on a 2010 Buick Lucerne even when the original trim would have used 235/55R17 or 245/50R18. The car’s current wheel diameter and overall setup matter as much as the original sub-model specification.
A Lucerne with aftermarket wheels should be checked for actual wheel width, steering clearance, and fender clearance before a tire is chosen. That is especially important when moving between the car’s 17-inch and 18-inch fitment paths, because the correct tire decision depends on the hardware on the car rather than trim badge alone.
What should I inspect before driving a 2010 Buick Lucerne on new tires?
Before driving a 2010 Buick Lucerne on new tires, inspect the wheels for damage, confirm lug hardware condition, and make sure tire pressure is set appropriately for the installation. It is also wise to look over suspension and steering components so the new tires are not being asked to compensate for worn mechanical parts.
A road-ready check should also include clearance at full steering lock and a close look at alignment-related wear patterns on the old tires. Since many Lucernes are low-mileage cars today, pay attention to age-related issues elsewhere on the vehicle as well, including bushings and shocks, because those can affect how the new tires behave.
How often should tires on a 2010 Buick Lucerne be inspected?
Tires on a 2010 Buick Lucerne should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Pressure, tread condition, sidewall cracking, bulges, cuts, and any signs of uneven wear all deserve routine attention, even when the car appears to have plenty of tread left.
A low-use Buick can age its tires out before it wears them out, so inspection should become part of normal pre-drive preparation rather than something saved for service intervals alone. Occasional checks of air loss and visual condition help catch problems early, particularly on collector-kept cars that may spend extended time parked indoors.
