The 2007 Buick Lucerne sits in the final chapter of Buick’s traditional full-size sedan formula, combining front-wheel-drive comfort with a substantial highway-car feel that still appeals to owners who want quiet cruising and clean, formal styling. Tire fitment on the 2007 Buick Lucerne is trim-specific, with 225/60R16, 235/55R17, and 245/50R18 radial sizes tied to different sub-models. That makes the first decision less about brand and more about confirming whether the car is a CX, CXL, or CXS. From there, the choice shifts to sidewall style, tire series, and the balance between stock-type road manners, visual character, and wheel compatibility.
Which Tire Size Is Right for The 2007 Buick Lucerne
Three primary tire sizes apply to the 2007 Buick Lucerne, and they are separated by sub-model and wheel diameter rather than by interchangeable options on the same setup. The most important step is confirming whether the car is a CX, CXL, or CXS, then matching that trim to its 16-inch, 17-inch, or 18-inch rim before comparing sidewall treatments, tire series, and product details.
In 225/60R16, the 225 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 2007 Buick Lucerne, this is a modern radial fitment used with a 16-inch wheel and aimed at the more comfort-oriented setup. Available choices include Goodyear, BFGoodrich, and Travelstar, with sidewall treatments such as raised yellow letter, redline, pin white stripe, wide whitewall, and narrow whitewall. It is the right size to evaluate when matching a Lucerne CX to the proper wheel and the appearance you want.
The size 235/55R17 uses a 235-millimeter nominal section width, a 55-series profile, radial construction, and a 17-inch rim. For the 2007 Buick Lucerne, this size supports a different trim and wheel package than the 16-inch and 18-inch options, so it should be chosen only after confirming the car’s exact configuration. Product choices span BFGoodrich, American Classic, and Coker Classic, with blackwall, goldline, redline, and wide whitewall options across several tire series. This size gives the buyer the broadest mix of traditional appearance choices and more modern-looking blackwall selections.
A 245/50R18 tire has a 245-millimeter nominal section width, a 50-series profile, radial construction, and an 18-inch rim diameter. On the 2007 Buick Lucerne, this size belongs to the largest wheel setup in the lineup, making wheel confirmation especially important before any purchase. Available options in this size come from Pro-Trac in the Street Pro III series, with raised white letter and redline sidewall presentations. It is the size to focus on when the car carries the CXS-style 18-inch package and the goal is to preserve that larger-wheel visual stance.
Tire fitment on the 2007 Buick Lucerne varies directly by sub-model, and each trim uses its own wheel diameter and tire size. Checking the badge or confirming the actual wheel on the car matters before comparing products, because CX, CXL, and CXS do not share the same setup.

2007 Buick Lucerne CX
The 2007 Buick Lucerne CX uses the 225/60R16 radial size on a 16-inch wheel. Tire selection here is mainly about choosing the right sidewall presentation and tire series while keeping the wheel diameter and general comfort-oriented fitment in line with the CX setup.
The 2007 Buick Lucerne CXL uses the 235/55R17 radial size on a 17-inch wheel. That opens up a wider mix of blackwall and traditional sidewall treatments, so the choice often comes down to whether the car is being kept in a clean contemporary look or a more restoration-inspired style.
The 2007 Buick Lucerne CXS uses the 245/50R18 radial size on an 18-inch wheel. That makes wheel confirmation especially important, and the buying decision centers on retaining the larger-wheel fitment while choosing between the available sidewall styles in that 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)

Tire Size & Fitment
What tire size fits a 2007 Buick Lucerne?
The 2007 Buick Lucerne uses three different radial tire sizes depending on sub-model: 225/60R16, 235/55R17, and 245/50R18. Those sizes are tied to different trims rather than being universal options for every Lucerne, so the correct fitment starts with identifying whether the car is a CX, CXL, or CXS.
Once the trim is confirmed, match the tire to the actual wheel diameter on the car. A Lucerne that has been fitted with different wheels over time may no longer match its original trim-based setup, so checking both the sidewall size already on the car and the wheel diameter helps prevent ordering the wrong tire.
What size rim does a 2007 Buick Lucerne use?
A 2007 Buick Lucerne can use a 16-inch, 17-inch, or 18-inch rim, depending on sub-model. The CX uses the 16-inch setup with 225/60R16 tires, the CXL uses the 17-inch setup with 235/55R17 tires, and the CXS uses the 18-inch setup with 245/50R18 tires.
Rim diameter is the first fitment checkpoint because none of these tires can mount correctly on the wrong wheel size. If the car has aftermarket wheels, confirm the wheel diameter stamped on the rim and compare that with the tire size you plan to use before narrowing the choice by sidewall style or brand.
Do all 2007 Buick Lucerne sub-models use the same tire size?
No. The 2007 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 uses 245/50R18, so the proper tire depends on the exact trim and wheel package on the car.
That distinction matters because the three sizes also correspond to three different rim diameters. Even if two tires look close in overall proportions, that does not make them interchangeable, and a previous owner may have changed wheels. Checking the trim badge and the actual wheel size is the safest starting point before comparing available tires.
Choosing the Right Tire
What should I consider when choosing a 2007 Buick Lucerne tire?
Start with the correct size for the exact sub-model and wheel diameter, then compare the tires within that fitment by construction, sidewall style, tire series, and rim-width suitability where that specification is given. The Lucerne uses radial tires throughout, but the available products vary widely in visual character from understated blackwalls to whitewalls and redlines.
A buyer keeping a Lucerne close to its formal sedan appearance may focus on whitewall, goldline, or redline options, while a more contemporary look may point toward blackwall or lettered sidewalls. It also helps to compare load figures, weight, and wheel-width compatibility when those details are available, especially on cars with non-stock wheels.
What sidewall styles are available for 2007 Buick Lucerne tires?
Sidewall choices for the 2007 Buick Lucerne include raised yellow letter, redline, pin white stripe, wide whitewall, narrow whitewall, blackwall, goldline, and raised white letter, depending on tire size. The available styles are not the same across all three fitments, so the visual options change with the wheel and trim package.
That means sidewall style should be chosen after the size is settled, not before. A CX owner shopping 225/60R16 may see different appearance choices than a CXL owner in 235/55R17 or a CXS owner in 245/50R18, so it makes sense to compare style within the correct size rather than across the whole Lucerne range.
What brands offer tires for the 2007 Buick Lucerne?
Tires for the 2007 Buick Lucerne are available from Goodyear, BFGoodrich, Travelstar, American Classic, Coker Classic, and Pro-Trac, depending on the size. Brand availability changes by fitment, so the 16-inch, 17-inch, and 18-inch tires do not all offer the same brand mix or the same tire-series choices.
Brand is best treated as one part of the decision rather than the only one. Once the correct Lucerne size is confirmed, compare each brand’s available sidewall treatment, tire series, rim-width specification, and overall presentation so the tire matches both the vehicle’s wheel setup and the appearance you want to maintain.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Buick Lucerne?
A period-style 2007 Buick Lucerne usually starts with keeping the correct trim-based tire size and wheel diameter in place, then choosing a sidewall treatment that matches the car’s formal full-size sedan character. Depending on size, that can include whitewall, narrow whitewall, redline, or goldline radial options rather than only contemporary blackwall designs.
Appearance should be balanced with the actual wheel setup on the car, especially if it has changed hands or been modified. For owners pursuing exact showroom-era detail, Buick-specific brochures, club guidance, and original vehicle documentation are useful references, because period-style appearance and exact factory-delivered appearance are not always the same thing.
Which sidewall style suits a period-style 2007 Buick Lucerne?
For a period-style 2007 Buick Lucerne, whitewall-oriented options often complement the car’s upscale, traditional Buick presentation, especially on CX and CXL applications where wide whitewall, narrow whitewall, or pin white stripe choices are available. Redline and goldline options also create a deliberate visual statement, while blackwall and lettered styles lean more modern or performance-oriented.
The right look depends on the trim, wheel diameter, and how formal or sporty the finished car is meant to appear. Since sidewall offerings vary by size, it helps to confirm the tire size first and then choose the sidewall that best matches the Lucerne’s stance, wheel design, and overall presentation rather than chasing a style that is unavailable in that fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Buick Lucerne?
Yes. Modifications such as aftermarket wheels, altered suspension height, wheel-offset changes, or brake upgrades can affect tire fitment on a 2007 Buick Lucerne even when the tire size looks close to stock. The Lucerne already uses three different wheel diameters across its sub-model range, so any change from the original setup deserves a careful fitment check.
Wheel diameter is only part of the equation. Tire section width, sidewall shape, steering clearance, and fender room all matter once a car moves away from its original wheel package, so owners should verify actual wheel dimensions and inspect for rubbing at full lock and through suspension travel before committing to a replacement tire.
What should I inspect before driving a 2007 Buick Lucerne on new tires?
Before driving a 2007 Buick Lucerne on new tires, inspect wheel condition, valve stems, lug hardware, and the condition of the suspension and steering components that influence alignment and tire wear. Tire pressure should be set correctly for the application, and each tire should be checked for proper seating, no visible damage, and no immediate air loss.
A short test drive should be followed by another visual check for clearance and any sign of rubbing, especially if the car has different wheels than it originally used. It also helps to confirm that tread is clearing the fenders and inner wheelhouse cleanly during turning, braking, and normal suspension movement.
How often should tires on a 2007 Buick Lucerne be inspected?
Tires on a 2007 Buick Lucerne should be inspected regularly, not only by mileage but also by time and storage conditions. A quick pressure and condition check before routine use is smart, and a more thorough inspection for tread wear, cracking, cuts, bulges, and uneven wear patterns should be part of normal maintenance.
Cars that see occasional use deserve extra attention because age-related deterioration can appear even when tread depth still looks acceptable. Owners should also watch for slow air loss and irregular wear that may point to alignment or suspension issues, since catching those problems early helps protect both the new tires and the Lucerne’s road manners.
