Dropping tire pressure to deliver in a sandy area?

If the dual tires start to touch each other in the sand, wouldn't that damage the sidewalls?

 

sandy with a foundation or sandy with no foundation?

 

Just air back up before pavement.

 

just get a set of these

 

Stop in the street and make sure they have a machine and a cable there, if not make them sign something they are on the hook for a tow truck past the curb

 

With the steel ply in the sidewalls you have to worry about “pinch” damage if run too low. Sidewall Zippers can happen when you air back up to normal operating pressure.
