The 2008 Buick Lucerne sits in the final era of traditional full-size Buick sedans, blending front-drive comfort with the upscale, quiet-road character that longtime Buick buyers expected. It was offered in several trims, and tire fitment changes with the sub-model, so the first step is matching the car to its correct wheel and tire package. This Lucerne uses radial tires in three modern metric sizes: 225/60R16, 235/55R17, and 245/50R18. Available choices range from blackwall and raised white letter styles to redline, goldline, and whitewall treatments. For a stock car, the priority is confirming trim level and rim diameter before comparing appearance, series, and intended driving use.
Which Tire Size Is Right for The 2008 Buick Lucerne
Three tire sizes apply to the 2008 Buick Lucerne, and the right one depends on the exact sub-model and wheel diameter. The CX uses a 16-inch fitment, the CXL uses a 17-inch fitment, and the CXS and Super use an 18-inch fitment. Before choosing a tire, confirm the trim level and check the actual wheel size on the car, especially if wheels have ever been changed.
225/60R16 is a metric radial size with a 225-millimeter section width, a 60-series aspect ratio, and fitment on a 16-inch rim. On the 2008 Buick Lucerne, this size serves the CX and reflects a modern passenger-car radial setup rather than an older bias-ply format. Available choices include Goodyear, BFGoodrich, and Travelstar, with sidewall treatments such as raised yellow letter, redline, pin white stripe, wide whitewall, and narrow whitewall. This size makes sense when the car still carries its original 16-inch wheel package and the goal is to balance correct fitment with the preferred visual style.
235/55R17 is a metric radial size that uses a 235-millimeter section width, a 55-series profile, and a 17-inch rim. For the 2008 Buick Lucerne, this is the size associated with the CXL, placing it between the smaller CX fitment and the larger 18-inch setup used on higher trims. Product choices include BFGoodrich, American Classic, and Coker Classic, with blackwall, goldline, redline, and wide whitewall options across several tire series. It is the right size to evaluate when the car is equipped with 17-inch wheels and the decision is more about style, brand, and series than basic fitment.
245/50R18 is a metric radial size with a 245-millimeter section width, a 50-series aspect ratio, and fitment on an 18-inch rim. On the 2008 Buick Lucerne, this size belongs to the CXS and Super, giving those trims the largest wheel-and-tire package of the group. Current choices center on Pro-Trac Street Pro III radials with either raised white letter or redline sidewall styling, keeping the selection focused but visually distinct. This size should be considered when the car has the correct 18-inch wheel setup and the buyer wants to retain the trim-specific fitment while choosing the sidewall presentation that suits the car.
Tire fitment for the 2008 Buick Lucerne varies by sub-model rather than staying consistent across the entire lineup. Checking the exact trim matters because the Lucerne uses three different radial sizes on three different rim diameters, and that changes the starting point for every tire decision.

2008 Buick Lucerne CX
The 2008 Buick Lucerne CX uses the 225/60R16 radial size on a 16-inch wheel package. That makes tire selection more about comparing available brands and sidewall styles within the correct size than sorting through multiple fitment paths.
The 2008 Buick Lucerne CXL uses the 235/55R17 radial size with a 17-inch rim. For this trim, the key is staying with the correct 17-inch fitment and then deciding whether a blackwall, redline, goldline, or whitewall presentation best suits the car.
The 2008 Buick Lucerne CXS uses the 245/50R18 radial size on an 18-inch wheel. Tire choice here is straightforward on size, but the buyer still needs to confirm the actual wheel setup and choose between the available sidewall treatments in this trim-specific fitment.
The 2008 Buick Lucerne Super also uses the 245/50R18 radial size on an 18-inch rim. That shared fitment keeps the main decision centered on sidewall appearance and wheel compatibility rather than changing to a different primary 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.

Tire Size & Fitment
What tire size fits a 2008 Buick Lucerne?
The 2008 Buick Lucerne uses three different radial tire sizes depending on sub-model. The CX uses 225/60R16, the CXL uses 235/55R17, and both the CXS and Super use 245/50R18. Those sizes correspond to 16-inch, 17-inch, and 18-inch wheel packages rather than one universal fitment across the entire Lucerne range.
The practical step is to identify the exact trim and then verify the actual wheel diameter on the car. Many used sedans have had wheels changed over time, and that can blur the original fitment. Once the sub-model and wheel size are confirmed, the remaining decision is choosing among the available radial tires, series, and sidewall styles in that specific size.
What size rim does a 2008 Buick Lucerne use?
A 2008 Buick Lucerne can use a 16-inch, 17-inch, or 18-inch rim depending on the sub-model. The CX is paired with a 16-inch fitment, the CXL with a 17-inch fitment, and the CXS and Super with an 18-inch fitment. Rim diameter changes with the tire size, so it is an essential part of matching the car correctly.
Checking wheel diameter first prevents choosing the right tire size for the wrong wheel. A quick look at the sidewall and the wheel itself can confirm whether the car still has its expected setup. Wheel width also matters once the diameter is confirmed, especially when comparing among different tire lines within the same Lucerne fitment.
Do all 2008 Buick Lucerne sub-models use the same tire size?
No, the 2008 Buick Lucerne does not use one shared tire size across all sub-models. The CX uses 225/60R16, the CXL uses 235/55R17, and the CXS and Super use 245/50R18. That means trim level directly affects both tire size and wheel diameter.
This matters because a Lucerne owner should not choose tires by model name alone. The right starting point is the exact sub-model, followed by a check of the wheel currently on the car. Once those match, it becomes much easier to compare available products by sidewall treatment, tire series, and intended appearance without drifting into the wrong size range.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Buick Lucerne?
Start with the correct trim-specific size: 225/60R16 for CX, 235/55R17 for CXL, and 245/50R18 for CXS and Super. From there, compare the tire's construction, series, sidewall style, and wheel-width compatibility. The Lucerne is a modern radial-fitment car, so the main choice is not bias-ply versus radial, but which radial best suits the car's appearance and use.
A stock, comfort-oriented sedan may call for a different visual presentation than a more personalized car. Whitewall, redline, goldline, blackwall, and raised white or yellow letter styles all create a different look. It also helps to compare load figures and product details where available, especially if the car sees regular highway use or carries passengers frequently.
What sidewall styles are available for 2008 Buick Lucerne tires?
The 2008 Buick Lucerne has a wide spread of sidewall styles across its applicable tire sizes. Depending on the size, available styles include raised yellow letter, redline, pin white stripe, wide whitewall, narrow whitewall, blackwall, goldline, and raised white letter. The exact choices vary by tire size, so sidewall selection follows fitment rather than replacing it.
That variety lets the Lucerne lean toward understated factory-inspired appearance or a more customized presentation. A CX on 16-inch tires has different visual options than a CXS or Super on 18-inch tires, and the CXL sits in between with several decorative sidewall choices. Once the correct size is confirmed, sidewall style becomes one of the most visible differences among otherwise compatible tires.
What brands offer tires for the 2008 Buick Lucerne?
Tires for the 2008 Buick Lucerne are available from Goodyear, BFGoodrich, Travelstar, American Classic, Coker Classic, and Pro-Trac. Brand availability depends on the tire size, so not every brand appears in every Lucerne fitment. Some sizes also have more series and sidewall choices than others.
The useful way to compare brands is within the correct size for the car's sub-model. A CX owner may be looking at a different brand mix than someone shopping for a CXL or Super. Once the size is settled, compare each brand's series character, sidewall style, rim-width range, and any load information that matters for how the Lucerne is driven.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Buick Lucerne?
A period-style 2008 Buick Lucerne starts with the correct trim-specific radial size and wheel diameter, then narrows to the sidewall appearance that best matches the car's character. Whitewall, narrow whitewall, redline, goldline, and blackwall options are all available depending on size. For this Buick, visual authenticity usually comes more from staying with the proper size than from one universal sidewall choice.
The best approach is to match the tire's overall presentation to the Lucerne's trim and how the car is being preserved. A cleaner, more formal sedan may look at home on whitewalls, while a sportier or customized look may point toward redline or lettered sidewalls. When exact showroom-era appearance matters, period brochures or marque-specific references are worth checking.
How does tire construction affect the appearance of a restored 2008 Buick Lucerne?
On a 2008 Buick Lucerne, construction itself is straightforward because the primary fitments are radial across all sub-models. The visible difference comes less from choosing between bias-ply and radial and more from the tire series, sidewall treatment, and overall profile within the correct modern metric size. That keeps the restoration question focused on presentation rather than converting construction type.
A Lucerne restored with stock-style wheels will usually look most cohesive when the tire size and wheel diameter match the trim package the car was built around. After that, sidewall styling does the visual work. Whitewall or narrow whitewall choices can emphasize Buick's traditional luxury image, while redline, blackwall, or raised-letter designs push the appearance in a different direction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Buick Lucerne?
Yes, modifications can change tire fitment on a 2008 Buick Lucerne even when the tire size appears close to stock. Aftermarket wheels, altered wheel width, changed offset, suspension lowering, or body modifications can all affect clearance. Since the Lucerne already uses three different factory wheel diameters across its trims, modified cars need an especially careful check before tire selection.
A smart inspection includes confirming wheel diameter and width, then checking inner clearance, outer fender clearance, and steering travel. Cars that have been changed from their original trim package should not be matched by trim name alone. Looking at the actual wheel-and-suspension setup on the car avoids buying a correct-size tire for a wheel or clearance package that is no longer stock.
What should I inspect before driving a 2008 Buick Lucerne on new tires?
Before driving a 2008 Buick Lucerne on new tires, inspect the wheels, valve stems, and basic alignment condition, and confirm that the tire size matches the car's trim and rim diameter. It also helps to look over the suspension and steering for wear that could affect how the new tires sit or wear. Proper inflation matters from the first miles onward.
A road-ready check should also include verifying that there is no rubbing at full steering lock and no interference over bumps. On a car that has sat for long periods, look for old wheel damage, uneven wear from the previous set, or signs of air loss. Catching those issues early helps the new tires wear evenly and keeps the Lucerne more stable on the road.
How often should tires on a 2008 Buick Lucerne be inspected?
Tires on a 2008 Buick Lucerne should be inspected regularly, especially if the car is driven infrequently or stored for long periods. A quick visual check for cuts, bulges, cracking, uneven wear, and low pressure is worthwhile before routine driving, and a closer inspection at service intervals helps catch developing issues. Tire condition matters as much as tread depth on an older daily driver or collector-kept sedan.
Consistent inspections are particularly useful on a Lucerne because trim-specific wheel packages can mask problems if the car has changed hands or had wheel swaps. It is wise to monitor pressure, tread wear pattern, and sidewall condition over time rather than waiting for a problem to become obvious. Storage away from heat, sunlight, and ozone sources also helps preserve seldom-used tires.
