A Citroen C1 (2005–2014) uses a 4x100 PCD and a centre bore of 54.1 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 54.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 54.1 mm.
Offset: the original is ET35 to ET40. 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 M12x1.25, tightened to 100 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 155/65R14, 165/65R14. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

Vehicles with the same PCD and centre bore
Same 4x100 PCD and same 54.1 mm centre bore: wheels from these vehicles bolt on and centre on a Citroen C1 without rings. Offset, width, diameter and caliper clearance still need checking.
These vehicles also use 4x100 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 54.1 mm, and will not fit if it is smaller.
A Citroen C1 (2005–2014) has a PCD of 4x100: 4 studs or bolts spaced around a circle 100 mm in diameter.
Does a Citroen C1 need a hub centric ring?
The centre bore (hub diameter) of a Citroen C1 is 54.1 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 Citroen C1?
The recorded original offset is ET35 to ET40 depending on the version and wheel size. 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 Citroen C1?
The specified tightening torque is 100 Nm for M12x1.25 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 Citroen C1?
With the same PCD (4x100) and the same centre bore (54.1 mm), these include: Hyundai Inster, Hyundai Bayon, Toyota Aygo X, Hyundai i20 III. Offset, width and rim diameter still need checking for each vehicle.
