расчет количество зубьев шестеренки при смене диаметра колес.
Just plug your numbers into the following equation:
(Old tire dia. X Old speedo gear)/New tire dia.
29 X 19/33
= 16.69 (17 tooth)= New speedo gear
There is a similar equation for use when calculating speedo gear changes after you change differential gear ratios it is as follows:
(Speedo gear teeth\Old gear ratio)X New gear ratio = New speedo gear
Still using the first scenario lets suppose that sometime after you upgraded your tires you decide to change gears in your front and rear differentials with a set of 4.10’s. The equation would look like this:
(17/3.55)X 4.10 = 19.6 (20 tooth)
