Mazda Mazda3 / Mazda3 MPS / Mazdaspeed3 BK wheel fitment
The BK Mazda3 uses relatively high factory offsets, while MPS owners commonly fit wider 17- or 18-inch wheels. Wider tyres often bring the rear arch lips and front suspension clearance into play.

Explained in our guides
Read these before choosing wheels for the Mazda3 / Mazda3 MPS / Mazdaspeed3: 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.

- Front and rear

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
- Mazda specifies 88–118 Nm for the original wheel nuts. The range is retained here because torqueNm accepts only a single number.
- Aftermarket examples are MPS fitments; do not assume identical brake and body clearance on every regular Mazda3.
- The MPS has 18x7 ET52.5 factory wheels. Do not confuse the BK wheel with the wider BL MPS wheel.
- Check spoke clearance and stud engagement when using the spacers shown in the track example.
- 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.
