Buick Regal Wheels and Rims

Buick Regal Aftermarket Wheel Fitment

The Buick Regal is a midsize sport sedan with one of the more complicated platform histories in the Buick lineup. The modern Regal ran across three platform eras and the bolt pattern changed twice. The 1992-1996 (4th gen) and 1997-2004 (5th gen) Regals were built on the GM W-body platform and ran 5x115 with a 70.3mm hub bore. The 2011-2017 (6th gen) Regal moved to the Opel Insignia A platform and the bolt pattern changed to 5x120 with a 66.9mm hub bore. The 2018-2020 (7th gen) Regal Sportback, TourX wagon, and GS moved to the Opel Insignia B platform and the bolt pattern reverted to 5x115 with a 70.3mm hub bore. So a 2017 Regal and a 2018 Regal carry different bolt patterns despite consecutive model years. The Regal was discontinued in North America after the 2020 model year. Element Wheels tracks the Regal by generation, and the Regal GS with Brembo front brakes is tracked as its own variant because the larger front caliper tightens front-wheel clearance compared with the base Regal. The collector 1978-1987 Regal (the G-body era that produced the Grand National turbo Regal) runs a different 5x120.65 / 5x4.75 collector pattern and is covered on the Buick Grand National hub.

The Buick Regal Bolt Pattern

The Regal has used two different bolt patterns across the modern era and the pattern changes twice. The 1992-2004 W-body Regals ran 5x115 with a 70.3mm hub bore. The 2011-2017 Insignia-based Regal switched to 5x120 with a 66.9mm hub bore. The 2018-2020 Sportback, TourX, and GS reverted to 5x115 with a 70.3mm hub bore on the new Opel Insignia B platform. The lug count is 5 across every modern Regal. The thread pitch is M14x1.5 on the 2011-2017 Insignia A and M12x1.5 on the W-body and Insignia B generations.

A 5x115 and 5x120 bolt circle differ by only 5mm, which is close enough to look almost identical at the lug, but the studs do not seat correctly across patterns and the wheels do not safely interchange. Force-fitting a 5x120 wheel onto a 5x115 hub (or the reverse) puts stress on the lugs that will eventually fail. Confirm your year and pattern before ordering. The 2017 Regal and the 2018 Regal are consecutive model years on different patterns. Compare across the rest of the Buick lineup at our Buick wheels and rims hub.

Why the Regal Bolt Pattern Flipped Mid-Era

The 2011 Regal was a clean break from the older W-body cars. GM brought the Opel Insignia A from Europe and badged it as the Regal for the North American market. The Insignia A ran the European 5x120 bolt pattern with a 66.9mm hub bore. That spec stayed on the Regal through the 2017 model year. For the 2018 model year GM launched the all-new Opel Insignia B, sold here as the Regal Sportback, the TourX wagon, and the Regal GS. The Insignia B reverted to a 5x115 bolt pattern with a 70.3mm hub bore. So consecutive 2017 and 2018 model years carry different bolt patterns despite both being called Regal and both being Insignia-derived.

The Regal GS is the performance variant we track as its own row in the catalog. The 6th gen 2011-2017 Regal GS adds a larger front Brembo caliper to the base Insignia A platform. The 7th gen 2018-2020 Regal GS uses an AWD V6 powertrain and a larger front caliper compared with the Sportback. The larger front caliper tightens the inner-barrel clearance the wheel needs to clear. Bolt pattern and hub bore on each GS still match the base car of the same generation (5x120 / 66.9mm on the 6th gen GS, 5x115 / 70.3mm on the 7th gen GS). What changes is the front wheel-face clearance window.

How We Confirm Fitment on Buick Regal Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including the modern Regal generations. For the Regal that means clearance from the wheel to the fender, gap between the back of the wheel and the suspension, brake caliper height (especially on the GS Brembo variant), hub protrusion, lug seat depth, and turning clearance with 19 to 20 inch wheels installed. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. We don't pull specs from manufacturer sheets the way most retailers do.

Every wheel we recommend is backed by our Fitment Guarantee. If a wheel does not fit, we pick up the wheels and refund 100 percent. No risk to you.
