I'm looking at putting 285/70/17 or 285/75/17 on my stock 06 f-250...

What does the 285 and the 70 mean..thanks

285 is the width of the tire in millimeters. 70 is the percentage of the width and represents the sidewall height.

11.22" wide (divide 285 by 25.4 for inches) 7.854" (multiply the width by the aspect ratio) of side wall above and bellow the wheel, so multiply it by 2 before adding the wheel height for diameter.
