315mm tire width - 75% aspect ratio (percentage of the width of the tire that describes the height of the side wall) - 16 inch wheel


so  315 mm \ 25.4 to get the inches  is 12.4 inches x.75 = 9.3 inches

so 9.3 sidewall height + 16 inches (wheel diameter) + 9.3 (cant forget the tire height on the other side of the wheel)
so 9.3 + 16 + 9.3 = 34.6

so 315/75/16  =  34.6/12.4/16  or rounded off to 35/12.50/16

Seeing how the link is to a dead site, here is a site w/several 4wd Calculators, from crawl ratio to tire conversions.
