I have a transsmission with a final of 1 to 1 ratio now i have a transfer case with a ratio of 3 to 1. I also have 6.13 gears. and i have a set of Ag tires that measure
14.9x24 49 inches tall. any help would be great .

What transmission exactly you got? And what t-case?

The simple answer is 6.13 x 3 = 18.39:1 but if you need more info like speeds per rpm, etc check out the gear ratio calculator:
