Looking at the gear chart in CJ Pony, it is showing the same 16 tooth gear for both the 3.00 and the 3.25 unless theres a difference in F70-14 and FR70-14 tires? How can that be? The F70-14 tire is 24.78" tall, I'm running 245/60R15s that are 26.55" tall. I'm assuming with the bigger tires I would need maybe 1 tooth larger gear? I'm not that good with math, I just know my speed is about 15 MPH to fast right now and would like to get right with out buying and swapping a bunch of gears.
