Well I would say that 2470 seems low for 35" tires....So off the tire size you posted later (315/70/17) I did the math and got 2741.9 unloading circumference(I think thats right). So I guess take off 7% squish from that number and you should be closer to correct(im not sure what it is can't do the math in my head). Then just follow the instructions that Jack has said for entering it into the custom options.
