Please explain more as this makes absolutely no sence. LESS tire pressure equals more traction and this is a proven fact. I used to be an avid off-roader back in my younger days and can remember getting stuck due to loss of traction. I could sometimes break free by dropping the pressure in the tires. Many off-road vehicles have a button on the dash that will allow you to drop the tire pressure for off-roading and then air them back up. Many customs jeeps have similar set ups. It was not uncommon for me to run 12-15 lbs while off-roading and that's without bead locks. Guys with bead locks a would drop their pressure down to 7-10 lbs! All to gain traction.

Please explain how increasing tire pressure increases traction.
