NO!                                                                             
when driving in sand, the object is to float on the sand.                       
otherwise, your belly be dragging and your wheels be hanging.                   
hence, low tyre pressures, so they don't cut in and sink.                       
when driving in snow, the object is to get the tires on the pavement.           
in this case, low pressure = no traction
