For the fourth generation MX-5, Mazda reverted back to the 4-stud wheel fitment used on the early cars. The new car's wheel fitment is PCD 4x100 with a centre bore measurement of 54.1mm. The wheel nut size is M12 x 1.5 and the factory specification offset was ET +45. It's possible to fit lower offset and/or wider wheels for a more aggressive stance.
The standard tyre sizes used were 195/50/16 and 205/45/17. When fitting wheels you should fasten the four wheel nuts in a criss-cross pattern to a torque between 108-147Nm. The standard tyre pressure for cars fitted with 195/50/16 tyres is 29psi. Here I've put together a list of wheels featured on the ND models.

Tyre Rotation
