F350 tire airing down ranges w/ truck camper

I live on an island and drive on beach. For many years I pulled a tandem construction trailer loaded with treated lumber and built stairways, decks access to beach homes. Deflated tires on truck and trailer to 15-20 PSI but never lower than 15. 20 PSI will do fine in most cases. That will be the most recommended PSI. Beach driving is an art very different from highway driving. Drive slow and do not spin the wheels and make no sudden turns. Different beaches have different speed limits. Check with local authorities for permits and local regulations for beach driving.

Snow driving keep tires up to proper inflation and start slow and stop slow and do not make any sudden turns. Reduce speed at all times on snow.
