A Polestar Polestar 4 (from 2024) uses a 5x108 PCD and a centre bore of 63.4 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 63.4 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 63.4 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 M14x1.50, tightened to 140 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Vehicles with the same PCD and centre bore
Same 5x108 PCD and same 63.4 mm centre bore: wheels from these vehicles bolt on and centre on a Polestar Polestar 4 without rings. Offset, width, diameter and caliper clearance still need checking.
Will wheels from another vehicle fit your Polestar 4?
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 5x108 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 63.4 mm, and will not fit if it is smaller.
A Polestar Polestar 4 (from 2024) has a PCD of 5x108: 5 studs or bolts spaced around a circle 108 mm in diameter.
Does a Polestar Polestar 4 need a hub centric ring?
The centre bore (hub diameter) of a Polestar Polestar 4 is 63.4 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 Polestar Polestar 4?
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 Polestar Polestar 4?
The specified tightening torque is 140 Nm for M14x1.50 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 Polestar Polestar 4?
With the same PCD (5x108) and the same centre bore (63.4 mm), these include: Polestar Polestar 3 axe arrière, Polestar Polestar 3 axe avant, Polestar Polestar 2, Polestar Polestar 1 axe arrière. Offset, width and rim diameter still need checking for each vehicle.
