← Mazda Miata NB (1999-2005 US model years)
Will 15x8 +34 to +36 wheel (4x100), e.g. 949 Racing 6UL fit a Mazda Miata NB (1999-2005 US model years)?
Short answer: Yes, reportedly. Reported
Yes, reportedly: On an NB the same wheel is easier still: the SuperMiata table says 225/50 fits NBs fine and 225/45 clears with stock alignment, and a separate wheel guide lists 15x8 +30 to +35 for 205/50 or 225/45 with a possible roll when lowered.

Details
On an NB the same wheel is easier still: the SuperMiata table says 225/50 fits NBs fine and 225/45 clears with stock alignment, and a separate wheel guide lists 15x8 +30 to +35 for 205/50 or 225/45 with a possible roll when lowered. The maker says the current 6UL (+34, 67.1 mm bore, lug-centric) clears NB Sport brakes. Short-body coilovers with more bump travel can still bring the tire into the liner.
