Buick LaCrosse Wheels and Rims

Buick LaCrosse Aftermarket Wheel Fitment

The Buick LaCrosse is Buick's full-size sedan and ran for three generations in North America from the 2005 through 2019 model years. The bolt pattern is the headline story across the lineup. The 1st gen (2005-2009) was built on the GM W-body platform and ran 5x115 with a 70.3mm hub bore. The 2nd gen (2010-2016) moved to the GM Epsilon II platform and the bolt pattern changed to 5x120 with a 66.9mm hub bore. The 3rd gen (2017-2019) moved again to the GM P2XX platform and the pattern reverted to 5x115 with a 70.3mm hub bore. So the 1st gen and the 3rd gen share a pattern, but the 2nd gen in the middle is different. Element Wheels tracks LaCrosse fitment by generation. The 2nd gen also supports optional staggered fitment in our catalog (wider rear width available), where the 1st gen and the 3rd gen are square front to rear by default. The LaCrosse was discontinued in North America after the 2019 model year.

Find Your Buick LaCrosse Generation

Pick your year range to see wheels and rims that fit your specific LaCrosse. The bolt pattern is 5x115 on the 1st gen, 5x120 on the 2nd gen, and 5x115 again on the 3rd gen. Confirm your year before ordering since 5x115 and 5x120 wheels do not safely interchange.

The Buick LaCrosse Bolt Pattern

The LaCrosse has used two bolt patterns across its three generations, and the pattern flips between adjacent generations. The 1st gen (2005-2009) ran 5x115 with a 70.3mm hub bore on the GM W-body platform. The 2nd gen (2010-2016) moved to 5x120 with a 66.9mm hub bore on the GM Epsilon II platform. The 3rd gen (2017-2019) reverted to 5x115 with a 70.3mm hub bore on the GM P2XX platform. The lug count is 5 across every generation. The thread pitch is M12x1.5 on the 1st gen and 3rd gen and M14x1.5 on the 2nd gen.

A 5x115 and 5x120 bolt circle differ by only 5mm. The patterns look close at the lug but the studs do not seat correctly across patterns, and wheels do not safely interchange. Force-fitting a 5x120 wheel onto a 5x115 hub (or the reverse) puts stress on the lug studs that will eventually fail. Confirm your year before ordering. Note that a 1st gen LaCrosse wheel and a 3rd gen LaCrosse wheel WILL share the same pattern (5x115), but the middle 2nd gen will not cross with either.

Why the LaCrosse Bolt Pattern Flipped Between Generations

The LaCrosse rode on three different GM platforms across its three generations and each platform brought its own spec. The 1st gen LaCrosse shared the GM W-body chassis with the contemporary Buick Century and Regal, both 5x115 cars. The 2010 redesign moved the LaCrosse to the GM Epsilon II platform, which is the same architecture as the contemporary Buick Regal and the Chevrolet Malibu of that era, and the Epsilon II carries a 5x120 bolt pattern with a 66.9mm hub bore. The 2017 redesign moved the LaCrosse to the GM P2XX platform (the same platform used on the 2017 and up Chevrolet Impala), which runs 5x115 with a 70.3mm hub bore. The pattern flipped twice because the LaCrosse moved between three different platform families.

The 2nd gen LaCrosse (2010-2016) supports optional staggered fitment in our catalog. The square setup runs the same width front and rear. The staggered option pushes a wider tire on the rear with a slightly narrower wheel up front, which gives the 2nd gen a more aggressive stance without changing bolt pattern, hub bore, or offset window. The 1st gen and the 3rd gen are square front to rear by default in our catalog. The 2nd gen is the only LaCrosse generation where the optional stagger is part of the published fitment window.

How We Confirm Fitment on Buick LaCrosse Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including all three LaCrosse generations. For the LaCrosse that means clearance from the wheel to the fender, gap between the back of the wheel and the suspension, brake caliper height, hub protrusion, lug seat depth, and turning clearance with the larger 20 to 22 inch wheel diameters installed on the 2nd and 3rd gen builds. The 2nd gen staggered window gets its own measurement pass on the rear axle. 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.
