Buick Regal Years With the Same Recorded Mounting Specs

2017

5×115, 5×120 · 66.9 mm, 70.3 mm · M12×1.5, M14×1.5

These years share the same recorded core mounting specs. Wheel diameter, width, offset, brake clearance, and load rating must still be checked.

2011–2016

5×115, 5×120 · 66.9 mm, 70.3 mm · M14×1.5

These years share the same recorded core mounting specs. Wheel diameter, width, offset, brake clearance, and load rating must still be checked.

1999–2004

5×115 · 70.3 mm · 1/2"-20UNF, M12×1.5

These years share the same recorded core mounting specs. Wheel diameter, width, offset, brake clearance, and load rating must still be checked.

Wheel Specification Changes

  • 2016 → 2017 – Thread size changed from M14×1.5 to M12×1.5, M14×1.5
  • 2004 → 2011 – Bolt pattern changed from 5×115 to 5×115, 5×120
  • 2004 → 2011 – Center bore changed from 70.3 mm to 66.9 mm, 70.3 mm
  • 2004 → 2011 – Thread size changed from 1/2"-20UNF, M12×1.5 to M14×1.5

Is matching bolt pattern enough?

A matching Buick Regal bolt pattern is only the first check. The wheel still has to clear the hub, brakes, and suspension, sit at a usable offset, and use the correct fasteners and tire package.

  • Center bore must not be smaller than the hub. A larger bore may need hub-centric rings; it is not an automatic fit.
  • Offset and backspacing change inner and outer clearance even when diameter matches.
  • Wheel width, brake clearance, and suspension travel are trim-specific and are not proven by bolt pattern alone.
  • Lug-seat geometry, thread size, load rating, tire diameter, and TPMS compatibility still need a physical check.

Same recorded specifications are a candidate for further verification, not confirmation that wheels physically fit.

Frequently Asked Questions

What bolt patterns has the Buick Regal used?

Recorded Buick Regal bolt patterns for 1999–2017 are 5×115, 5×120. A year may have more than one configuration, so confirm the year page before buying wheels.

Do all Regal years use the same wheel specs?

No. Recorded Regal wheel specifications change across model years, including a documented transition from 2004 to 2011. Use the year comparison tool and the specifications table on this page.

How can I compare two Regal years?

Use Compare Years at the top of this page to select a donor year and an installed-on year. The result compares recorded bolt pattern, center bore, thread size, rim diameter, rim width, offset, backspacing, and tire size, then links to both year pages and the wheel calculator.

Is matching the bolt pattern enough?

No. Matching bolt pattern alone is not enough. Center bore, offset, backspacing, wheel width, brake and suspension clearance, lug-seat geometry, load rating, tire diameter, and TPMS compatibility must still be verified.

What should I check before installing wheels from another year?

Confirm the recorded core mounting specs, then verify wheel width, offset/backspacing, brake and suspension clearance, lug-seat geometry, load rating, tire diameter, and TPMS compatibility. This page reports recorded specifications and does not certify installation.
