Buick Cascada Wheels and Rims

Buick Cascada Aftermarket Wheel Fitment

The Buick Cascada is the convertible Buick sold in the US market from 2016 through 2019, a rebadged version of the Opel Cascada that GM brought stateside to anchor the Buick lineup at the convertible slot. The bolt pattern is 5x115 with a 70.3mm hub bore across every Cascada model year, with M12x1.5 thread pitch and conical seat lug nuts. Fitment is square front to rear by default. There is no Brembo or upgraded factory caliper variant. Element Wheels carries direct fitment for the 2016-2019 Cascada and the catalog runs from 20 inch through 22 inch diameter, larger than most Buick sedans of the same era because Cascada buyers commonly upgrade to a larger wheel that suits the convertible body and the soft top profile. The Cascada was discontinued after the 2019 model year as Buick pivoted the lineup to crossovers and SUVs.

Find Your Buick Cascada Year

Pick your year range to see wheels and rims that fit your specific Cascada. The Cascada ran a single generation in the US market from 2016 through 2019. Bolt pattern, hub bore, and thread pitch are consistent across every production year and across the base, Premium, and Sport Touring trims.

The Buick Cascada Bolt Pattern

The Cascada runs the 5x115 bolt pattern with a 70.3mm hub bore across every production year (2016 through 2019). Lug count is 5. Thread pitch is M12x1.5. Lug type is conical seat (lug nuts, not bolts). This 5x115 / 70.3mm spec is the same one Buick used on the Verano, the Regal of the same era, the Lucerne, and several other Buick platforms. The bolt-on architecture lines up across those platforms though brake clearance and offset windows differ by car.

A note on imperial nicknames. The 5x4.5 imperial label refers to 5x114.3 alone. 114.3mm equals exactly 4.5 inches, which is where the imperial name comes from. The Cascada is 5x115 specifically. It is not 5x114.3, and the imperial 5x4.5 nickname does not apply. The 5x115 and 5x114.3 bolt circles differ by only 0.7mm but the studs do not seat correctly across patterns and the wheels do not safely interchange. Force-fitting a 5x114.3 wheel onto a Cascada hub puts stress on the studs that will eventually fail. Confirm the 5x115 pattern before ordering.

The Cascada and the Opel Convertible It Was Built From

The Buick Cascada that arrived in US showrooms for the 2016 model year was a rebadged Opel Cascada, the convertible Opel had been building for the European market since 2013. GM brought the car to the US under the Buick brand to give Buick a soft top model that the lineup had been missing. Mechanically and structurally the US Cascada is closely related to the European Opel Cascada, with the convertible top, body, and chassis carried over essentially unchanged. The Buick-market changes were limited to badging, market-specific equipment, and the trim hierarchy.

For aftermarket wheel fitment, the Cascada is one fitment box across all four US production years and across the base, Premium, and Sport Touring trims. Same 5x115 bolt pattern. Same 70.3mm hub bore. Same M12x1.5 conical seat lug nuts. Same brake clearance front and rear. No Brembo upgrade. No AWD. No factory staggered fitment. The aftermarket diameter range on the Cascada runs larger than most other Buick sedans of the same era because Cascada owners more often build the convertible up to a 20 or 22 inch wheel to fill the fender and suit the convertible profile.

How We Confirm Fitment on Buick Cascada Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including the 2016-2019 Cascada. For the Cascada that means clearance from the wheel to the fender, gap between the back of the wheel and the suspension, brake caliper height, hub protrusion past the mounting surface, lug seat depth, and turning clearance front and rear with 20 to 22 inch wheels installed. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. The Cascada's 70.3mm hub bore matches other Buick platforms from the same era so hub centric ring sizing is straightforward. We do not 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.
