So here’s the idea. We alll find online calculators useful. How about everyone use this thread to post online CAR RELATED calculators (i.e. tire calculators, temperature calculators, etc) that they find useful here. Maybe we can get enough useful stuff to where this can become a sticky. I only ask two things: 1. Read the thread carefully. 2. Do not post duplicate calculators (which shouldn’t happen if you follow step one). Lets see how this goes. It may be a bit messy in the beginning, but I will go through as the thread develops and start grouping them in order. I will post the grouped/organized stuff in this thread as time goes on. _ **Wheel and Tire** _ Here’s one that’ll tell you percentage changes in your speedo when you change tire and/or rim sizes [http://www.miata.net/garage/tirecalc.html](http://www.miata.net/garage/tirecalc.html) wheel offset calculator, came in very useful when buying bigger wheels.
