Where
 speed = MPH - miles per hour tire radius, tire diameter, rim diameter = inches gear ratio = if ring and pinion ratio is 4.10:1 use 4.10 rotation velocity = RPM - revolutions per minute effective gear ratio = determine new gear ratio after a tire size change crawl ratio = four wheel drive rear axle differential, transfercase low range and transmission ratios section width = millimeters aspect ratio = unitless
