    calculate circumference of tire = C=2*pi*r = 2*3.14812 = 75.36

    5280 ft in a mile

    calculate feet per hour = 5280/34 = 179,520 ft/hr

    find inches per hour 179520*12 = 2154240

    calculate inches / minute = 2154240/60 = 35904 inches per minute

    divide that by tire circumference

    35904/75.36 = 476.43 revolutions per minute
