Explained in our guides
Read these before choosing wheels for the Focus ST: they explain the offset, fitment and hub numbers in this guide.
- Wheel offset explained: choosing ET without guessingUnderstand positive and negative wheel offset, calculate inner clearance and outer position, and choose an ET using measurements from your own car.
- Flush, poke and tucked fitment: measure the whole tyreUnderstand flush, poked and tucked wheels, calculate how width and offset change the look, and check clearance beyond a parked side-on photograph.
- Hub-centric vs lug-centric wheels: choosing hub ringsLearn what hub rings do, how to specify their inner and outer diameters, and why centring, wheel seats and vibration need separate checks.

Width and offset guidance
Offset range
Check the exact setup
There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.
Common width limit
Measure before ordering
A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.
These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.
Clearance notes
- Ford online ST technical data describes the bore as 2.5 inches / 63.5 mm, while aftermarket fitment databases use 63.4 mm. The manufacturer value is retained here; obtain hub rings specified for this Focus application.
- Ford specifies 135 Nm, equivalent to about 100 lb ft, for the wheel nuts.
- These examples do not establish clearance for an RS brake conversion or other larger brake kit.
- The lowered 19-inch example is a hatchback; estate load and body-clearance requirements still need checking.
- Check full steering lock and suspension travel with the car loaded. Match wheel load rating, tyre load and speed ratings, fastener seats and brake clearance.
