Use the calculator to see what happens to your speedometer reading when you change the size of your tires and wheels.
Check out this website...Simple but useful..

this dont work for me, my speedo is way slow. i have another speedo lying around here somewhere that gives more accurate results but without tach
Please paste it here...
I guess Levin is talking about this onehttp://www.miata.net/garage/tirecalc.html
I already compared with miata.. the readings are same... and there are lot of other sites on the web offering this calculator in different styles but the readings are again same..means everyone using same formula behind.....
okies...Miata surely is easy to use as it gives a percentage rather then a new reading for every speed.
