Wheels from Mazda MX-5 ND on Toyota Aygo X: compatible?

No, the centre bore is too small

Same 4x100 PCD, but the centre bore of the wheels from Mazda MX-5 ND (54.1 mm) is smaller than the hub of Toyota Aygo X (60.1 mm): they will not fit without being re-bored by a professional.

Before fitting the wheels

An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of Toyota Aygo X (M14x1.50), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
