19.5 inch tires on the beach?

Hello all, I live 5 miles from Sandy neck beach in Sandwich, Ma. This beach is for off road use only. You must have a self contained unit for overnight camping and a 4x4 for daily use. All tires must be aired down to 18 psi as its very soft sand. I have been told that the 19.5 inch tire should not be aired down due to its construction. If you do it can loose its bead while airing down or blow out at highway speed after it has been aired down. Well is this true? If so what tire/rim can I install. I have a 04 Coachmen Mirada 30 QB on a F53 chassis. Thanks, Marcdohc

You are correct. You cannot lower the air pressure of that tire with that weight of the motorhome. It will damage the tire and can result in a dangerous situation while driving on the highway for you and other vehicles.
