Why These Wheels Fit

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares:

  • Bolt pattern / PCD
  • Center bore direction (donor wheel bore must not be smaller than the hub)
  • Wheel diameter, width, and offset against known OEM ranges
  • Lug thread / hardware differences (vehicle-side hardware)

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.

Known OEM Fitment For 2000 Buick Regal

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.

Center bore70.3 mm
Thread sizeM12 x 1.5
Factory wheel diameter16 in
Factory wheel width6.5 in
Wheel offsetET 42 mm
Backspacing4.9 in
Known factory tire size example215/70R15

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.

How To Use The Wheel Interchange Calculator

  • Open the calculator on this page. Set Installed on to 2000 Buick Regal to lock in your vehicle baseline.
  • Set Wheels from to the donor vehicle you are considering. This lets you compare key dimensions side by side.
  • Use Custom wheel size to try different rim diameter, width, and offset. As you change rim diameter, the calculator updates tire diameter in the comparison view.
  • Use Custom tire size to adjust section width and aspect ratio so overall tire diameter stays close to your stock setup. The goal is to minimize speedometer error and avoid rubbing.
  • Watch the clearance readouts for suspension, fender, and brake components. Pay attention to inner clearance when increasing width or moving to lower offsets and to outer poke when moving to higher widths or lower aspect ratio tires.
  • Confirm bolt pattern is 5x115 and center bore is at least 70.3 mm. If the wheel bore is larger than 70.3 mm, plan on hub-centric rings to properly center the wheel.
  • When results look acceptable, compare to your door placard and owner’s manual. If anything conflicts, follow OEM guidance.
  • Before buying, plan a test fit on the car with the exact wheel and tire if possible to verify caliper, strut, and fender clearance at full lock and over bumps.

Fitment Checklist Before You Buy

  • Bolt pattern must be 5x115. Do not rely on near-matches.
  • Center bore should be 70.3 mm. If the new wheel bore is larger, use hub-centric rings sized to 70.3 mm to your wheel’s center bore.
  • Thread size is M12 x 1.5. Match lug nuts or bolts to the wheel’s seat type and required length.
  • Offset should be close to ET 42 mm. Small changes may be workable after confirming inner and outer clearances with the calculator and a physical test fit.
  • Wheel width changes affect inner clearance and outer poke. Validate both in the calculator and on the car.
  • Overall tire diameter should remain close to stock to reduce speedometer error and prevent rubbing. Use Custom tire size to tune this.
  • Verify brake caliper and spoke clearance, especially with smaller offsets or different spoke designs.
  • Check load rating of wheels and tires meets or exceeds vehicle requirements.
  • TPMS: If your car is equipped with sensors, confirm compatibility and plan for sensor transfer or new sensors.
  • Always confirm final sizes on the driver door placard and in the owner’s manual or OEM service information.

Plus Sizing And Common Upgrades

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:

  • Overall tire diameter remains close to your stock setup.
  • Offset stays close enough to maintain inner clearance and avoid excessive outer poke.
  • Width increases do not contact struts, control arms, or fenders under compression or steering lock.
  • Tire load index and speed rating meet or exceed OEM requirements.

Winter setups sometimes downsize wheel diameter with a taller sidewall for better protection. Validate brake clearance and tire diameter in the calculator before committing.

Installation Tips

  • Inspect and clean the hub face and wheel mounting pad. Remove rust and debris for true seating.
  • Dry-fit a front and rear wheel to check caliper and fender clearance before mounting tires.
  • If aftermarket wheels have a larger center bore, install hub-centric rings sized to 70.3 mm at the hub and your wheel’s bore.
  • Hand start all lug nuts. Tighten in a crisscross pattern in stages.
  • Torque to the OEM specification listed in your owner’s manual. Do not rely solely on impact tools for final torque.
  • Re-torque lug nuts after 50 to 100 miles of driving.
  • After installation, perform a slow full-lock turn in both directions and drive over gentle bumps to listen for contact.

Tools And Helpful Supplies

Confirm all parts match your exact wheel seat type, center bore, and vehicle requirements before purchase.

FAQs

  • 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.
