Not to brag but thanks to the NPS I was booked onto a Four wheel Driving program in the Mojave Desrt. Part of my on the job traing. The instructor said "airing down is THE number one way to get one-self un-stuck in sand or snow". He also recommended airing down prior to getting stuck is even better. Lots of folks that do the off-roads travel as part of their regular path air down as soon as they leave the pavement. Most of those people also have on-board compressors..they don't take nearly the time of the small portables. Another intersting point is that for rigs with rear duallies? nuh uh...can't air down...the rear tires will rub together. And yes one can buy gizmos that 'might' keep them apart but no gaurantees and fit is an issue too. I cannot mount them on mine.
