These are vehicle-year records whose recorded OEM ranges overlap this 2006 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 2006 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.

Recorded vehicle-side thread differs (M14x1.5 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. Approximate position vs the mid OEM package: outer change -0.67 mm, inner change -5.68 mm.

Recorded vehicle-side thread for the 2006 Buick Lucerne is M12x1.5. This donor year is recorded as 1/2"-20UNF. 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 following specs are confirmed for at least one factory configuration of the 2006 Buick Lucerne. Trims and option packages can differ. If your vehicle’s door-jamb tire label or owner’s manual shows different values, use those and verify changes with the on-page calculator and OEM documentation.
| Bolt pattern | 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 |
Backspacing and offset are linked. If you change wheel width or offset, always check inboard clearance to the strut, spring perch, and brake hoses, and outboard clearance to the fender and liner.
The calculator lets you compare a donor wheel and tire to your 2006 Buick Lucerne before you buy. It also supports custom wheel and tire sizes.
Always confirm final choices with OEM sources and a hands-on test-fit. Trim-to-trim brake package and suspension differences can affect clearance.
Plus sizing changes rim diameter and adjusts tire profile to keep overall diameter similar to stock. Because clearances can vary by trim and brake package, the following are examples for calculator comparison only, not guarantees of fitment for the 2006 Buick Lucerne:
Enter these sizes in the calculator and evaluate inner and outer clearances against OEM. Final fitment depends on wheel width, offset, spoke design, and your specific vehicle configuration. Always test-fit before mounting tires.
What is the bolt pattern on the 2006 Buick Lucerne?
5x115. Both the stud count and the 115 mm circle must match.
Can I use 5x114.3 wheels on a 5x115 car?
No. Mixing patterns risks vibration, improper seating, and hardware failure. Use exact 5x115 wheels.
What is the center bore?
70.3 mm. Aftermarket wheels with a larger bore should use hub-centric rings sized to 70.3 mm.
What thread size do I need?
M12 x 1.5. Verify lug seat style for your wheel design before purchasing hardware.
What is the stock tire size shown here?
225/60R16 for the configuration listed above. Your vehicle may differ by trim, so confirm on the tire label and owner’s manual.
What wheel offset should I use?
OEM reference is ET 46 mm. If you change width or offset, use the calculator to check inner and outer clearances and then test-fit.
Will 17 or 18 inch wheels fit my Lucerne?
Fitment can vary by trim and brake package. Use the calculator to compare overall diameter and clearances, then physically test-fit before buying.
What torque should I use on the lug nuts?
Torque specs vary. Refer to your owner’s manual or OEM service information for the exact value and use a torque wrench.
Can I reuse my factory lug nuts on aftermarket wheels?
Only if the seat type, diameter, and shank depth match the new wheel. Many aftermarket wheels require different lug nuts.
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.
