These are vehicle-year records whose recorded OEM ranges overlap this 2000 Buick Regal. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 69 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.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Recorded vehicle-side thread for the 2000 Buick Regal is 1/2"-20UNF. 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 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. Width/offset ranges overlap; confirm diameter and brake clearance for your trim.

The following values are known for at least one factory configuration of the 2000 Buick Regal. Some specs can vary by trim or option package. If your vehicle’s placard or manual shows a different size, use the on-page calculator and confirm against OEM sources before purchasing.
| Bolt pattern | 5x115 |
| Center bore | 70.3 mm |
| Thread size | M12 x 1.5 |
| Factory wheel diameter | 16 in |
| Factory wheel width | 6.5 in |
| Wheel offset | ET 42 mm |
| Backspacing | 4.9 in |
| Known factory tire size example | 215/70R15 |
Note: The tire size above is a known example from one Regal configuration. Other trims used different factory tire sizes that are not listed here. Always verify your exact tire size on the driver door placard and match your wheel diameter accordingly.
Plus sizing means increasing wheel diameter while using a lower profile tire to keep overall tire diameter close to stock. For example, if your Regal is on a 16x6.5 ET 42 wheel, a typical plus one would be a 17 inch wheel with an appropriate tire profile that keeps overall diameter similar. If your Regal has a factory 15 inch tire package, plus one would be a 16 inch wheel with a matched tire. Use the calculator to model options and ensure:
Winter setups sometimes downsize wheel diameter with a taller sidewall for better protection. Validate brake clearance and tire diameter in the calculator before committing.
Confirm all parts match your exact wheel seat type, center bore, and vehicle requirements before purchase.
Will wheels with 5x114.3 fit my 5x115 Buick Regal?
No. Near-match patterns are not a safe substitute. Use 5x115 and verify all other specs with the calculator and OEM information.
Do I need hub-centric rings on the Regal?
If your aftermarket wheels have a center bore larger than 70.3 mm, use rings sized to 70.3 mm at the hub and your wheel’s exact bore. If the wheel bore is exactly 70.3 mm, rings are not needed.
What offset range works on the Regal?
The known OEM offset is ET 42 mm. Keep new wheels as close as possible and confirm inner and outer clearance using the calculator. Always test fit before mounting tires.
What is the stock tire size for 2000 Buick Regal?
Tire size varied by trim. A known example is 215/70R15. Other trims used different sizes that are not listed here. Check your driver door placard and owner’s manual to confirm your exact size.
What is the correct lug nut torque?
Refer to the owner’s manual or OEM service information for the exact torque specification. Tighten in a crisscross pattern and re-torque after initial driving.
Can I use wheel spacers?
Use only quality hub-centric spacers that maintain proper hub engagement and thread engagement, and verify clearance with the calculator and a test fit. Follow OEM torque procedures.
How do I confirm which of the listed specs apply to my car?
Match your door placard tire size and load rating, compare your OEM wheel markings, and use the calculator with 2000 Buick Regal selected. If anything conflicts, prioritize OEM documentation or consult a dealership parts department with your VIN.
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.
