The P 255 50 R19 tires have an OD of 29.6 inches. Check my facts by using this calculator http://www.miata.net/garage/tirecalc.html . According to what this guy says, you can change to an 18 inch rim as long as the OD stays the same otherwise your speedometer, odometer and other diagnistics will get screwed up.

I helped to educate my service manager when he proposed changing the wheel and tire size on my 06HH for new winter tires. Best to stick with the same wheel and tires size - get after the tire manufacturers.
