A Fiat Seicento (1998–2010) uses a 4x98 PCD and a centre bore of 58.1 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 58.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 58.1 mm.
Offset: the original is ET33. 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 86 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 4x98 PCD and same 58.1 mm centre bore: wheels from these vehicles bolt on and centre on a Fiat Seicento without rings. Offset, width, diameter and caliper clearance still need checking.
Will wheels from another vehicle fit your Seicento?
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 4x98 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 58.1 mm, and will not fit if it is smaller.
A Fiat Seicento (1998–2010) has a PCD of 4x98: 4 studs or bolts spaced around a circle 98 mm in diameter.
Does a Fiat Seicento need a hub centric ring?
The centre bore (hub diameter) of a Fiat Seicento is 58.1 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 Fiat Seicento?
The recorded original offset is ET33. 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 Fiat Seicento?
The specified tightening torque is 86 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 Fiat Seicento?
With the same PCD (4x98) and the same centre bore (58.1 mm), these include: Fiat 500e, Fiat Panda III, Fiat Qubo, Fiat 500 (312). Offset, width and rim diameter still need checking for each vehicle.
