Buick Bolt Pattern & Center Bore Notes

Based on the 462 Buick fitment guides we cover, we have documented 13 distinct bolt pattern / center bore combinations across different Buick platforms and model years:

  • 5x115 bolt pattern, 70.3mm center bore — 227 models we cover, spanning 1982–2026.
  • 5x120 bolt pattern, 66.9mm center bore — 65 models we cover, spanning 2007–2026.
  • 5x105 bolt pattern, 56.6mm center bore — 56 models we cover, spanning 2004–2025.
  • 6x120 bolt pattern, 66.9mm center bore — 31 models we cover, spanning 2018–2026.
  • 5x127 bolt pattern, 70.3mm center bore — 21 models we cover, spanning 1965–1985.

  • 5x127 bolt pattern, 78.1mm center bore — 6 models we cover, spanning 1991–1996.
  • 6x127 bolt pattern, 78.3mm center bore — 5 models we cover, spanning 2003–2007.
  • 6x114.3 bolt pattern, 70.3mm center bore — 2 models we cover, spanning 2006–2007.

Do not mix platforms: a wheel forged for one Buick bolt pattern / center bore combination will not hub-center correctly on a different one, even if the diameter looks right. Always confirm your exact model and year against the bolt pattern and center bore listed on that model page below before ordering — or send us your VIN or trim level and we will confirm it for you.

Offset and backspacing recommendations vary by trim even within the same bolt pattern, mainly due to differences in brake caliper size and suspension geometry between base and performance trims. Every ANKUSI wheel is forged to your exact target offset, so send us your Buick model, year, and trim and we will confirm the correct spec before production — no guessing required.

How to check the bolt pattern on your Buick

The most common Buick fitment in our guide is 5x115 with a 70.3 mm center bore (227 of 462 model years we cover).

  1. Read the stamping on the back of an original wheel: size, offset (ET) and bolt pattern are usually cast into a spoke or the hub pad.
  2. No stamping? Measure center-to-center between two adjacent lug holes. For 5x115 that distance is 67.6 mm (PCD × sin(180° / 5)). A 2 mm difference already means a different bolt pattern.
  3. Match generation and year on the model pages below — the same nameplate can change bolt pattern or center bore between generations.

Changing width or offset? Check how far the wheel moves in or out with our offset & backspacing calculator.

Vehicles Using 5x115 With a 70.3 mm Center Bore

In our database, 88 other vehicle entries from 8 makes use exactly the same 5x115 bolt pattern and 70.3 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.

5x115 is used by 3.2% of the vehicle pages in our English fitment guide (209 of 6,503); 65.1% of those also use a 70.3 mm center bore.

Hub-Centric Rings for a 70.3 mm Center Bore

A wheel with a center bore larger than 70.3 mm needs a hub-centric ring. The most common combinations:

Wheel boreRing size
70.5 mm70.5 → 70.3 mm
71.6 mm71.6 → 70.3 mm
72.6 mm72.6 → 70.3 mm
73.1 mm73.1 → 70.3 mm

ANKUSI forged wheels are bored to exactly 70.3 mm for this vehicle, so no ring is needed.

Sources and Last Update

Bolt pattern and center bore were checked against at least two independent fitment references before publication.
