New product for off-road ...

[ironglow]

  A new product beingh intyroduced...automatic tire deflators. 

  When a driver decides to go off road and wants to deflate tires all around to the same PSI..he can preset thes valve caps to preferred pressure and
   just replace the regular caps with them..proper PSI will be set automatically.

   Here is a commercial my son recently for the manufacturer.  He did nearby, on the road leading up to, and in our own woods... using his own truck
    and one of his usual models.. You may see it on TV..

   I don't know how to pull it off facebook...sorry..      but for you guys on FB..enjoy

would have been handy back in the day when we went 4 wheeling. add in one of my dewalt 20volt air compreesor that you set a pressure and turn it on and it shuts off automatically when it hits that pressure
