A Smart Fortwo axe arrière (1998–2007) uses a 3x112 or 4x100 PCD and a centre bore of 57.1 or 60.1 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 57.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 57.1 mm.
Offset: the original is ET-1 to ET32. 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 M12x1.50, tightened to 110 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 155/60R15, 195/50R15, 165/65R15. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

Vehicles with the same PCD and centre bore
Same 3x112 PCD and same 57.1 mm centre bore: wheels from these vehicles bolt on and centre on a Smart Fortwo axe arrière without rings. Offset, width, diameter and caliper clearance still need checking.
A Smart Fortwo axe arrière (1998–2007) can have a 3x112 or 4x100 PCD depending on the version: check on an original wheel.
Does a Smart Fortwo axe arrière need a hub centric ring?
The centre bore (hub diameter) of a Smart Fortwo axe arrière is 57.1 or 60.1 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 Smart Fortwo axe arrière?
The recorded original offset is ET-1 to ET32 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 Smart Fortwo axe arrière?
The specified tightening torque is 110 Nm for M12x1.50 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 Smart Fortwo axe arrière?
With the same PCD (3x112) and the same centre bore (57.1 mm), these include: Smart Fortwo axe avant. Offset, width and rim diameter still need checking for each vehicle.
