Tire Sizing Calculator

http://www.miata.net/garage/tirecalc.html


Just saw this and decided it needs to be here. For those of you who would like to get your new rim/tire combo close to your stock tire height (for speedometer accuracy) this is the way to go.

for example, i'm going to run a 235/35/19 on my new rims, and my old ones were 225/50/16. it's just a tad larger with the new setup than the old, and my speedometer won't be off by much at all.
