A Cadillac XT6 (from 2020) uses a 6x120 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.
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 ET50. 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 190 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 235/55R20. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).
Vehicles with the same PCD and centre bore
Same 6x120 PCD and same 66.9 mm centre bore: wheels from these vehicles bolt on and centre on a Cadillac XT6 without rings. Offset, width, diameter and caliper clearance still need checking.
Choose the vehicle the wheels come from: we compare the hub, then each original wheel to the millimetre.
Same PCD, different centre bore
These vehicles also use 6x120 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 66.9 mm, and will not fit if it is smaller.
A Cadillac XT6 (from 2020) has a PCD of 6x120: 6 studs or bolts spaced around a circle 120 mm in diameter.
Does a Cadillac XT6 need a hub centric ring?
The centre bore (hub diameter) of a Cadillac XT6 is 66.9 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.
What offset (ET) for a Cadillac XT6?
The recorded original offset is ET50. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.
What tightening torque for the wheels of a Cadillac XT6?
The specified tightening torque is 190 Nm for Ecrous - 14x1.50 fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.
Which vehicles have the same PCD as a Cadillac XT6?
With the same PCD (6x120) and the same centre bore (66.9 mm), these include: Cadillac XT5, Cadillac SRX, Saab 9-4X, GMC Acadia. Offset, width and rim diameter still need checking for each vehicle.
