Tire lug nut turning tips.
Mechanics, tire lightening isn't a one-way-fits-all deal. You'll need to put on and tighten the lug nuts for your FMTV's tires to the left or right, depending on which side of the truck you're on.
Driver side wheel lug nuts get tightened to the left and passenger side wheel lug nuts get tightened to the right.
TO HELP YOU REMEMBER, THERE IS AN "L" IN THE MIDDLE OF THE LEFT SIDE LUG THREADS, AND AN "R" IN THE MIDDLE OF THE RIGHT SIDE'S.
TURN LEFT (OR COUNTER-CLOCKWISE) TO TIGHTEN WHENEVER YOU SEE THE "L" ...
... AND TURN RIGHT (OR CLOCKWISE) WHEN THE "R" IS SEEN.
