Mazda MX-5 Miata NA wheel fitment
The NA commonly moves from its original 14-inch wheels to lightweight 15-inch wheels. The narrower body needs more attention to arch clearance than the NB when fitting wider wheels and tyres.
4x100 bolt pattern · 54.1 mm centre bore · Stock wheels: 14 × 5.5, 14 × 6, 15 × 6 inch · Stock tyres: 185/60 R14, 195/50 R15

Explained in our guides
Read these before choosing wheels for the MX-5 Miata: 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.

15-inch wider road and track setup
- Front and rear
- 15 × 8 inch, ET25 · 205/50 R15
Good-Win specifies at least about 1.2 degrees of negative camber and a light arch roll on an NA with 205/50 tyres. This is not an unmodified-arch recommendation.
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 workshop torque reference gives 89–117 Nm for wheel nuts. A single value is omitted because the published specification is a range.
- Use M12x1.5 nuts with the correct conical seat for the wheel. A larger aftermarket centre bore needs an appropriate locating ring.
- At 15x8 ET25, Good-Win distinguishes the NA’s arch-roll requirement from the more accommodating NB body. Wide tyre shoulders and lowering further affect clearance.
- 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.

What tyres go with a common 15-inch NA upgrade?
205/50 R15 is a documented choice for 15x7 and 15x8 wheels, subject to the tyre maker’s permitted rim widths and the arch checks above.
What wheel size does the Mazda MX-5 Miata NA use?
Factory wheels are 14 × 5.5 inch, 14 × 6 inch and 15 × 6 inch, depending on trim. The stock table lists the offset for each.
What is the Mazda MX-5 Miata NA centre bore?
54.1 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
