The math is simple: 33 x pi x 25.4 = circumference without weight on the tires.
Multiply that result by 0.97 to account for the "squish" caused by weight which will give you a good starting point. For your tires, start with a value of 2554mm, and make adjustments from there.
Make sure your Gear Ratio is correct whenever you open the custom options menu! It might need to be changed.
