Common questions
What bolt pattern does the Buick LaCrosse have?
The LaCrosse full-size sedan (GM Epsilon platform) is 5×115 with a 70.3 mm hub and M12×1.5 bolts for 2005-2009 and 2017-2019; the 2010-2016 generation used a different 5×120/66.9mm/M14×1.5 fitment. Check the table above for your exact generation, and confirm against a wheel or the owner's handbook before buying.
Will other wheels fit my LaCrosse?
Only wheels with exactly the same bolt pattern — bolt pattern has no working tolerance. The centre bore must also be equal to or larger than the hub (a larger bore just needs spigot rings). A different pattern needs bolt-on adapters, which also push the wheel outward and change the track.
What is the centre bore on a LaCrosse?
70.3 mm on the current car — earlier generations may differ, see the table. The bore is the hole in the middle of the wheel; it has to clear the hub spigot or sit on a spigot ring.
Bolt pattern is only part of fitment. The offset (ET) decides where the wheel sits in the arch — work that out with the wheel offset calculator. For tyre sizing on a new wheel width, use the tire size calculator.
