Fitting wheels on a Opel Insignia B 2.0 Turbo 4x4, GSi
A Opel Insignia B 2.0 Turbo 4x4, GSi (2017–2022) uses a 5x120 PCD and a centre bore of 67.1 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 67.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 67.1 mm.
Offset: the original is ET41 to ET49. 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 M14x1.5, tightened to 190 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 235/45R18, 245/40R19, 245/35R20. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).
