Explained in our guides
Read these before choosing wheels for the Fiesta 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
- The Ford handbook specifies 135 Nm. Retailer catalogues identify M12x1.5 nuts and a nominal 63.4 mm hub.
- The Mk7 standard 205/40 R17 tyre is not the Mk8 factory 17-inch size.
- Lower offsets move the wheel towards the arch. Check full steering lock and suspension travel, particularly after lowering.
- 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.
