MX-5 Roadster ND Wheels

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

You can extend the life of your car's tyres by rotating them as shown in the graphic below.

Mazda's recommended interval for this is 5000 Km or about 3100 Miles.
