Can't help you anymore on the lift, but here is the tire formula:
Example: 285/75R16
285 = section width of the tire in millimeters (mm), 25.4 mm = 1 inch
75 = aspect ratio in percentage (how tall the sidewall of the tire is in relation to the width...lower number is generally consider more of a "low profie" type tire, higher the number is considered more of "tall and skinny" size). 75 = 75% = 0.75
16 = rim diameter in inches (don't ask me why the formula has inches, millimeters, and a percentage).
So...
285 mm = 11.2" = tire width
11.2" x 0.75 = 8.4" sidewall height (distance between edge of tread to edge of rim)
For the overall tire height (starting from the ground, bottom of tire, and going straight up to the top of the tire) =
8.4" (bottom sidewall) + 16" (rim height) + 8.4" (top sidewall) = 32.8"
Overall tire size = 32.8" tall x 11.2" wide for a 16" rim.
