Add that most folks don't understand the WHY's & HOW2's of airing down and low range
Airing down increases the tires contact patch and the 'apparent' dia increases to
over 8 FEET. Some tires will form a 'cup' at the center of the contact patch to
then gain more traction
Low range is not only to climb, but even in flats with loose stuff. Once traction
is broken and in too high a gear...the tires will spin to dig a grave
Anyone who has been out there watching will notice that the tires *WILL* break
traction, but if in compound low...will not spin and regain traction
Then the discussion on tire philosophy...penetration or floatation...vs terrain
and driving style...that is then factored by the equipment at hand...
