Will 15x8 +25 wheel (4x100) with 205/50R15 tire fit a Mazda Miata NA (1990-1997)?

Q: Will 15x8 +25 wheel (4x100) with 205/50R15 tire fit a Mazda Miata NA (1990-1997)?

Yes, with extra parts or work. Two wheel guides agree 15x8 +25 with a 205/50R15 is a popular NA setup that sits close to flush, and that a mild fender roll may be needed depending on ride height and camber (one suggests about -1.5 degrees). A 225/45R15 on the same wheel needs more fender work. NA owners on a forum report front tire contact over bumps until the front lips were rolled flat. The vendor's 15x8 +25 clears factory NA/NB brakes; aftermarket 4x100 wheels often have a 67.1mm bore, so centering rings are optional on the 54.1mm Miata hub.
