How to adjust your speedometer for bigger tires?
Ever wonder how far off your speedometer is with your new bigger tires? I’m using a simple ratio calculation, so this info will only approximate your corrected speed and depends on the accuracy of tire size diameters (assumimg nothing but tire size has changed).
What happens when you change the size of your tires?
When you put different size tires on your vehicle, your speedometer will no longer read the correct speed. Larger tires cause the speedometer to show slower speeds than reality, and smaller tires show faster speeds.

Why does the speedometer read how many revolutions?
Your speedometer is reading how many revolutions your tires are making not how fast they are spinning. When you go to bigger tires the circumference of the tires is larger, meaning the distance around the tire is longer. Thus, with each revolution you are traveling further than before.
