For better traction in sand, drop air pressure 10-12 pounds below normal pressure on conventional tires. (Return to normal pressure after use in these conditions.) Try high-range 4WD to maintain forward momentum. Depending on the condition of the sand, low-range 4WD and alternative gear selections may be necessary. Also try to make wider turns if at all possible. Tight turning slows the vehicle abruptly and can get you stuck. Again, maintaining forward momentum is key.
