Recorded vehicle-side thread for the 2017 Buick Regal is M14x1.5. 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.

Hub-centric rings of about 70.3 → 66.9 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore. Recorded vehicle-side thread differs (1/2"-20UNF on the donor year vs M14x1.5 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 -3.02 mm, inner change -16.03 mm. This uses aggregated width/offset ranges, not a specific wheel.

tl;dr

2017 Buick Regal: bolt pattern 5x120, center bore 66.9 mm, thread M14 x 1.5, nominal OEM wheel 19x8.5 ET45. Tire information varies by trim. Use the on-page calculator to confirm alternate wheel and tire combos before buying. Gotchas: a listed tire rim diameter of 18 may indicate multiple OEM wheel options.

Recommendation

Follow a four‑step lifecycle when selecting and fitting wheels. Verify fitment, choose hardware, test‑fit, and finalize with torque and alignment. Use the on‑page calculator to compare donor wheels and custom sizes. If any OEM value varies by trim, confirm with the dealer or your VIN.

  • Verify bolt pattern and thread size: 5x120, M14 x 1.5. These must match or be adapted with appropriate studs/bolts.
  • Confirm center bore: 66.9 mm. Use hub‑centric rings if aftermarket wheels have a larger bore.
  • Respect offset: OEM ET 45 mm. Keep offset close to avoid handling changes and rubbing.
  • Match rim width: OEM 8.5 in. Wider or narrower rims need tire and clearance checks via the calculator.
  • Confirm tire fit: OEM tire shown 235/50R18 but OEM rim diameter also listed 19 in. Use the calculator or VIN lookup to resolve this discrepancy.
  • Buy correct lug nuts and a calibrated torque wrench for final installation.

Impact

Wheel choices affect handling, speedometer, and brake clearance. A lower offset moves the tire outward. Wider rims change tire profile and clearance. Different overall diameter alters speedometer and ABS calibration. Testing on the vehicle reveals real clearance and steering behavior.

Use the calculator to model changes and see exact tire diameter and clearance effects before purchase. This resolves the rim/tire diameter mismatch quickly.

Risks

Be aware of common gotchas that cause returns or unsafe conditions.

  • Rubbing: Incorrect offset or too-wide rims can contact suspension or bodywork.
  • Hub mismatch: Wheels with a larger center bore require hub‑centric rings.
  • Lug fitment: Seat profile and thread engagement must match. Verify lug nut type.
  • TPMS and ABS: Different wheel/tire diameter can affect sensors and speed readings.
  • Load rating: Aftermarket wheels must meet or exceed vehicle load requirements. Check wheel specs.
  • Torque and safety: Under‑ or over‑torqued lug nuts risk wheel loss or warped rotors.

If any specification is unknown or differs by trim, confirm with the VIN, dealer parts department, or OEM service manual. The on‑page calculator helps validate size tradeoffs.

Next actions

Follow this compact checklist and next steps.

  • Use the on‑page calculator to compare donor wheels and custom sizes now.
  • Confirm rim diameter for your VIN. The 18 vs 19 discrepancy needs verification.
  • Measure hub bore and test the wheel on the hub before full installation.
  • Order hub‑centric rings if bore is larger than 66.9 mm, and correct lug nuts for M14x1.5.
  • Buy a quality torque wrench and torque to OEM spec when mounting wheels.
  • Post‑install: perform a low‑speed clearance test and then a professional alignment.

Quick tool links: torque wrench and hub‑centric rings help do the job safely.

Next steps: run the on‑page calculator, confirm VIN specifics, and schedule fitting. That will resolve unknowns and reduce risk.

Methodology and sources

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

  • 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.
