A Daihatsu Rocky (1987–1992) uses a 5x139.7 PCD and a centre bore of 108 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 108 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 108 mm.
Offset: the original is ET19. 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 Ecrous - 12x1.50, tightened to 99 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Tyres: original fitment is 225/80R15. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

Vehicles with the same PCD and centre bore
Same 5x139.7 PCD and same 108 mm centre bore: wheels from these vehicles bolt on and centre on a Daihatsu Rocky without rings. Offset, width, diameter and caliper clearance still need checking.
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 5x139.7 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 108 mm, and will not fit if it is smaller.
A Daihatsu Rocky (1987–1992) has a PCD of 5x139.7: 5 studs or bolts spaced around a circle 139.7 mm in diameter.
Does a Daihatsu Rocky need a hub centric ring?
The centre bore (hub diameter) of a Daihatsu Rocky is 108 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 Daihatsu Rocky?
The recorded original offset is ET19 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 Daihatsu Rocky?
The specified tightening torque is 99 Nm for Ecrous - 12x1.50 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 Daihatsu Rocky?
With the same PCD (5x139.7) and the same centre bore (108 mm), these include: Jeep CJ7. Offset, width and rim diameter still need checking for each vehicle.
