Fitting wheels on a Cadillac CT6

A Cadillac CT6 (from 2016) uses a 5x120 PCD and a centre bore of 66.9 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

PCD: 5x120 required. See all vehicles with 5x120.
Centre bore: the wheel must have a centre bore of 66.9 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 66.9 mm.
Offset: the original is ET35. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
Fixings: thread Ecrous - 14x1.50, tightened to 150 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 235/50R18. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

Vehicles with the same PCD and centre bore

Same 5x120 PCD and same 66.9 mm centre bore: wheels from these vehicles bolt on and centre on a Cadillac CT6 without rings. Offset, width, diameter and caliper clearance still need checking.
