Based on this, there should be about 1.5 inches of difference in diameter, which will increase your “gear ratio” by about 6%: [http://www.miata.net/garage/tirecalc.html](http://www.miata.net/garage/tirecalc.html) ---

It depends on your bolt pattern and offset of hubs. Your speedometer will be a good deal off. ---

If the base OEM tires are 15" and you don’t have oversized brakes, then they should work. You’ll have to fit them to be sure.
