Buick Park Avenue Wheels and Rims

Buick Park Avenue Aftermarket Wheel Fitment

The Buick Park Avenue is the full-size luxury sedan Buick built from 1992 through 2005, the flagship of the Buick range before the Lucerne consolidated the full-size lineup for the 2006 model year. The bolt pattern is 5x115 with a 70.3mm hub bore across every Park Avenue 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, including on the supercharged Ultra trim, so the same aftermarket wheel that clears the base Park Avenue clears the Ultra. Element Wheels carries direct fitment for the 1992-2005 Park Avenue and the catalog runs from 16 inch through 20 inch diameter.

Find Your Buick Park Avenue Year

Pick your year range to see wheels and rims that fit your specific Park Avenue. Bolt pattern, hub bore, thread pitch, and brake clearance are consistent from 1992 through the final 2005 model year, across both the C-body and the G-body generations.

The Buick Park Avenue Bolt Pattern

The Park Avenue runs the 5x115 bolt pattern with a 70.3mm hub bore across every production year (1992 through 2005). Lug count is 5. Thread pitch is M12x1.5. Lug type is conical seat (lug nuts, not bolts). This 5x115 / 70.3mm spec is shared with the rest of the Buick full-size lineup of the same era including the LeSabre, the Lucerne that replaced both, and the earlier W-body Regal and Century. 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 Park Avenue 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 Park Avenue hub puts stress on the studs that will eventually fail. Confirm the 5x115 pattern before ordering.

Park Avenue C-Body and G-Body Generations

The Park Avenue spans two generations across the catalog years. The 1991-1996 Park Avenue (the C-body, also tagged UPG in some references) was Buick's flagship full-size sedan, available in base and Ultra trim. The Ultra used a supercharged 3.8L V6 (the L67 in this period) and rode on the same C-body chassis as the base car. The 1997-2005 Park Avenue moved to the G-body, kept the supercharged Ultra option in the lineup, and remained the flagship until Buick consolidated the full-size sedan range into the single Lucerne nameplate for 2006.

For aftermarket wheel fitment, those two Park Avenue generations are one fitment box. Same 5x115 bolt pattern. Same 70.3mm hub bore. Same M12x1.5 conical seat lug nuts. Same brake clearance. Same fitment-window box front and rear. That holds true across base, Ultra, and the limited-run Final Edition Park Avenue. No Brembo upgrade option, no AWD complication, no factory staggered fitment.

How We Confirm Fitment on Buick Park Avenue Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including the 1992-2005 Park Avenue. For the Park Avenue 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 18 to 20 inch wheels installed. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. The Park Avenue 70.3mm hub bore matches several 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.
