Sinc you changed your gears and not tire size use this formula:
(#teeth on old gearXnew gear ratio)/Old gear ration = #teeth on new gear
Now when you change tire size use this formula:
(Old tire size X Old speedo gear)/new tire diameter = #teeth on new gear
(#teeth on old gearXnew gear ratio)/Old gear ration = #teeth on new gear
Now when you change tire size use this formula:
(Old tire size X Old speedo gear)/new tire diameter = #teeth on new gear
