Common questions
What bolt pattern does the Cadillac XT5 have?
The XT5 uses an unusual 6×120/66.9mm fitment (6 bolts rather than the more common 5) with M14×1.5 studs, unchanged since its 2016 launch. 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 XT5?
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 XT5?
66.9 mm on the current car. 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.
