The NC is the only MX-5 on a five-stud hub, so wheels from the NA, NB and ND do not fit. Its factory wheels sit at a high ET55, and owners usually move to 17x8 at around ET45 for a wider tyre that still clears standard arches.

Read these before choosing wheels for the MX-5 Miata: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
ThreePiece's NC fitment guide shows an NC3 on BC Racing coilovers running 17x8 ET45 Enkei RPF1s with 225/45 R17 tyres, arches not rolled and no rubbing, though it calls the fit tight.
Another car in the ThreePiece guide, an NC1 on coilovers, runs 17x8 ET45 Advan wheels with 215/45 R17 tyres on unmodified arches without rubbing.
The ThreePiece guide shows a 2009 NC2 on H&R springs, about 33 mm lower, running 16x8 ET38 Konig wheels with the factory 205/50 R16 tyre size.
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.
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.
Upload a photo and start with a look that suits the MX-5 Miata. Try the wheels, colour and stance before you spend on parts.
An AI preview shows the look. It cannot verify physical fitment.
