It's simple, my rpm at 55 is 2500, and I have 31 inch tires so you see how many rotations it takes your tires to go 55 miles, then take you RPMs and multiply it by 60 to get 55 miles per hour, so in my case I did a little more precise math this time and got 150000/36759 which ended up being 4.08 ration in fourth gear which is a 1:1 ratio
