4.10 it is.
Unless you've got an overdrive tranny the rear gear ratio is your final drive ratio.

Tires don't effect it at all. your speed vs rpm, yes. "efective" final drive, yes, but what most define as final drive ratio, no.

Your crawl ratio is 70.3601 to 1.

i was told that with the bigger tires it makes my truck act as if it had higher gears......but that wasnt what i was asking i meant the crawl ratio sorry for any confusion

Here is a good calculator that will give your final drive ratio for all gears of your transmission and hi/low on your t-case http://www.florida4x4.com/tech/gearcalc.php

I think the "final drive" number in the calculator is what others refer to as "crawl ratio".

Just multiply your lowest transmission gear, 4-low, and rear gears together.
