These are vehicle-year records whose recorded OEM ranges overlap this 2005 Buick LeSabre. 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.
Recorded OEM bolt pattern, center bore, and width/offset ranges overlap. This is not a guarantee that every wheel from the donor year fits this vehicle.
Recorded vehicle-side thread for the 2005 Buick LeSabre is 1/2"-20UNF. This donor year is recorded as M12x1.5. 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 (M12x1.5 on the donor year vs 1/2"-20UNF 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.

You have a 2005 Buick LeSabre with these OEM wheel specs: 5x115 bolt pattern, 70.3mm center bore, M12 x 1.5 thread, 16x6.5 rim, ET43 offset, 4.94 inch backspacing, and factory tire 215/70 (R15 listed). There is a mismatch between rim diameter (16) and tire rim diameter (R15) in the data. Confirm rim and tire diameters before buying wheels or tires. Use the on-page calculator and OEM sources to verify fitment.
First, verify the correct wheel rim diameter and tire rim diameter. Check the vehicle placard, owner's manual, or dealer parts department. Then use the site calculator to compare donor wheels to your LeSabre. If changing wheels, pick wheels that match 5x115 bolt pattern and 70.3mm center bore or plan hub-centric rings. Use M12 x 1.5 lug hardware sized for the wheel seat type. Choose tires that match the confirmed rim diameter and maintain overall diameter within safe tolerance.
Getting bore, bolt pattern, or thread wrong prevents safe installation. Correct bolt pattern ensures the wheel mounts to studs. Matching center bore prevents hub-centric runout. Correct lug nuts prevent stripped threads and loose wheels. A wrong tire-to-rim diameter pairing risks bead seating failure and speedometer error. Using the calculator shows changes in track width, speedometer, and clearance instantly.
Checklist for a quick, safe workflow.
Next steps: confirm dimensions, run the on-page calculator, then source hardware.

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.
