These are vehicle-year records whose recorded OEM ranges overlap this 2007 Buick Lucerne. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 62 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change -0.67 mm, inner change -5.68 mm. This uses aggregated width/offset ranges, not a specific wheel.

Recorded vehicle-side thread for the 2007 Buick Lucerne is M12x1.5. This donor year is recorded as M14x1.5. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.

Dataset suggestionWheel spacer ≈ 6.68 mm – not a verified installation requirement.
A spacer of about 6.68 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 6.68 mm farther inward than the mid OEM package. Recorded vehicle-side thread differs (1/2"-20UNF on the donor year vs M12x1.5 on the target vehicle). Hardware must match the target vehicle’s studs and the selected wheel’s seat. Existing hardware may be reusable if it already matches. Seat style is not confirmed in this dataset.
Only years with evidence-based interchange relationships are listed. Adjacent years are not assumed compatible.

The specifications below reflect a known factory configuration for the 2007 Buick Lucerne. Other trims or option packages may use different wheel sizes or offsets. If your door jamb tire placard or build sheet shows different values, use those as your baseline and verify with the on-page calculator and OEM sources.
| Bolt pattern (studs x PCD) | 5x115 |
| Center bore | 70.3 mm |
| Thread size | M12 x 1.5 |
| Rim diameter | 16 in |
| Rim width | 7.0 in |
| Wheel offset (ET) | 46 mm |
| Backspacing | 5.31 in |
| Tire size | 225/60R16 |
Overall tire diameter reference from the OEM tire size: 225/60R16 is about 26.6 in (676 mm). Aim to keep any new tire diameter within about 3 percent of this to protect ABS, traction control, and speedometer accuracy.
Unknowns or variations by trim: Some Lucerne trims may have come with larger factory wheels and different offsets. Confirm your exact factory spec using your door jamb placard, owner’s manual, or dealer parts lookup, then plug those numbers into the calculator as your baseline.
The calculator on this page lets you compare a potential donor wheel and tire against your 2007 Buick Lucerne. It also lets you try custom wheel and tire sizes and instantly see changes in clearance, poke, and rolling diameter.
Plus sizing can improve tire selection and appearance when done correctly. Use the calculator to keep the overall tire diameter close to the OEM reference of about 26.6 in and to manage inner and outer clearances.
Important: Specific larger OEM or aftermarket sizes can vary by trim and brake package. Do not assume another Lucerne’s wheel or a different GM 5x115 wheel will fit. Verify with the calculator and physical test fitting.
Can I install 5x114.3 wheels on a 5x115 Buick Lucerne?
No. The pitch circle diameter is different. This can cause poor seating, vibration, and stud stress. Use only 5x115 wheels.
Do I need hub-centric rings?
If the aftermarket wheel’s center bore is larger than 70.3 mm, use rings sized 70.3 mm to the wheel’s bore for proper centering and to reduce vibration.
What offset should I choose for aftermarket wheels?
Start from the OEM reference ET 46 mm and use the calculator to balance inner and outer clearance as width changes. Maintain safe inner clearance to the strut and avoid excessive poke.
Will bigger wheels affect my speedometer?
Only if the overall tire diameter changes. Keep the new tire’s overall diameter close to about 26.6 in and the speedometer difference will be minimal. The calculator shows the percent change.
Can I use wheel spacers?
Spacers change effective offset and can help with inner clearance, but they also reduce stud engagement and may affect bearing load. If you use spacers, choose hub-centric, high-quality parts and ensure proper stud engagement. Verify with the calculator and a test fit.
What torque should I use on the lug nuts?
Follow the torque specification in your owner’s manual or OEM service information for the 2007 Buick Lucerne. Do not guess. Torque with a calibrated wrench in a star pattern.
How do I confirm if my trim had different OEM wheel sizes?
Check the door jamb tire placard and owner’s manual, or provide your VIN to a Buick dealer parts department. Use those numbers as your baseline in the calculator.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
