The deeper down the rabbit hole I go while wearing a speedo…. That’s not correct.
I’ve read many of those TaoTao speedos are wrong. Possibly all are geared for 13” wheels.
Looks like 9T and 17T is what I would need.
Ive read the 8” wheels have 7T and 15T.
That seems to be correct to offset the 13% increase in tire circumference.
4.45’ x (17/9) = 8.4
3.93’ x (15/7) = 8.4
