premise: How do I get a lug nut off of my tire?
hypothesis: Place the small wrench on a lug nut and turn it counter-clockwise. Turn the wrench after you've secured it onto one of the nuts, pulling hard until you feel the lug nut begin to loosen. You don't need to remove the lug nut entirely, just use the wrench to loosen it until it's loose enough to remove with your fingers.
