I have a set of 4x100 14" Mazda wheels with winter tires (175/65R-14) I would like to use on the Fit (09)

The Fit center bore is slightly larger than the Mazda wheels so I need spacers to clear it.

Would 1/8" spacers be enough or do I need to go to 5mm or 1/4"?

Should have measured when the wheel was off but I only though of using spacers afterwards.
