Cool tire size calculators

Newbie here! Just wanted to share a couple of links that are very cool for figuring out tire sizes for stock versus upgrades! Hope this helps. Pay no attention to the name of the site though (miata,net).......

Both are done using two different formulas, the first one us using (pi)
(inches per Mile) 63360 / (pi) 3.1416 / Tire height

the second one not using (pi)by dividing 20800 by tire height I don't understand this formula but some use it because they do not understand "Pie"

Just use My Calculator it's better anyway.......
