When I plug those numbers into this site it says when the speedo says 100 I'm actually going 102.5.

However, when I use the calculator on this site it says when the speedo says 100 I'm actually going 97.56.

Not sure why I'm getting different numbers here. Any help would be appreciated, thanks!
Both answers are identical, just inverted in how they are displayed... change the order you plug them in and you will get the same numbers.

Ignore the numbers for a moment. Your current tires are taller than stock. Because of that, you are going faster than you would be going with the stock tires.
