A Ford Mustang S550 (2015–2023) uses a 5x114.3 PCD and a centre bore of 70.5 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 70.5 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 70.5 mm.
Offset: the original is ET40 to ET52.5. 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 M14x1.5, tightened to 204 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 235/50R18, 255/40R19, 275/40R19. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).
Generations of the Ford Mustang
Previous generation: Ford Mustang (1979–1993) — the bolt pattern changes (5x114.3 instead of 4x108): the wheels are not interchangeable. Next generation: Ford Mustang S650 (from 2024) — same 5x114.3 bolt pattern and same centre bore: original wheels swap between the two generations; check offset and diameter.
The original specs vary with the year, trim or wheel size. Identify your version from the tyre size marked on the sidewall.

Vehicles with the same PCD and centre bore
Same 5x114.3 PCD and same 70.5 mm centre bore: wheels from these vehicles bolt on and centre on a Ford Mustang S550 without rings. Offset, width, diameter and caliper clearance still need checking.
These vehicles also use 5x114.3 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 70.5 mm, and will not fit if it is smaller.
A Ford Mustang S550 (2015–2023) has a PCD of 5x114.3: 5 studs or bolts spaced around a circle 114.3 mm in diameter.
Does a Ford Mustang S550 need a hub centric ring?
The centre bore (hub diameter) of a Ford Mustang S550 is 70.5 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 Ford Mustang S550?
The recorded original offset is ET40 to ET52.5 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 Ford Mustang S550?
The specified tightening torque is 204 Nm for M14x1.5 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 Ford Mustang S550?
With the same PCD (5x114.3) and the same centre bore (70.5 mm), these include: Ford Mustang S650, Ford GT axe arrière, Ford GT axe avant, Ford Crown Victoria. Offset, width and rim diameter still need checking for each vehicle.
