Details
A Miata vendor says NBs should take 15x8 +25 with 205/50R15 without modification in most cases, because the NB has more fender room than the NA. Forum owners mostly agree (one reports no rubbing on a 2002 at about 12 inches hub-to-fender) but at least one says a roll was still needed, so treat it as height- and tire-dependent.
