A Smart Forfour Front (2014–2021) uses a 4x100 PCD and a centre bore of 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 60.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 60.1 mm.
Offset: the original is ET38. 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 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 4x100 PCD and same 60.1 mm centre bore: wheels from these vehicles bolt on and centre on a Smart Forfour Front 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 60.1 mm, and will not fit if it is smaller.
A Smart Forfour Front (2014–2021) has a PCD of 4x100: 4 studs or bolts spaced around a circle 100 mm in diameter.
Does a Smart Forfour Front need a hub centric ring?
The centre bore (hub diameter) of a Smart Forfour Front is 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 Forfour Front?
The recorded original offset is ET38. 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 Forfour Front?
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 Forfour Front?
With the same PCD (4x100) and the same centre bore (60.1 mm), these include: Smart Forfour Back, Smart Fortwo axe arrière, Smart Fortwo axe avant, Renault Twingo E-Tech. Offset, width and rim diameter still need checking for each vehicle.
