I really have to disagree with the majority here. You are talking about two completely different things. Driving down a washboard is not the same as hauling *** through the whoops, a shock is NOT going to make any noticeable difference in a washboard road. I will be the first one to preach that good shocks are worth every penny and shocks that you have spent the time, effort and money on to tune is what makes a vehicle do 20 over the whoops or do 60 over the whoops. When you are driving down a washboard road the frequency of the "bump" is much, much faster than a whoop or wash out in the road, and no shock is going to control a frequency that high. You are talking about dampening a "vibration" at that point. Most vehicle manufacturers dampen vibration with rubber bushings, in this case the tire is the rubber bushing, the softer the bushing the better it dampens the vibration.
I personally have driven many, many miles with 10 psi or less in my tires, even highway driving and have never had a tire failure from low tire pressure. I also believe that tire pressure is the key to any tires life and that tire pressure should always be monitored. If you buy a set of tires and just fill them up to manufactures max psi, you are wrong. It takes me about a month to dial in my tire pressure after a new set of tires, I monitor them very closely until I feel comfortable I have the pressure correct. I specifically put 15" wheels on my Cruiser because of the additional sidewall you gain with a 15" wheel and a 35" tire. I think this is the perfect combination for my set up and I can tell you it ride fantastic, even at 65-70 mph down severely wash boarded roads.
I do run bead locks, but that is because I live 50 miles from St. Anthony sand dunes and run the dunes a few times a month in the summer and I run way less than 10 psi. Never have I had a tire failure OR have a bead come off even when I didn’t have bead locks. I certainly am not suggesting that you all run your tires down to 15 psi for street use, but what I am saying is if I drive a 3000# buggy, or a 6000# cruiser the tire pressure is going to be different for each one over every different kind of terrain. Don't be afraid to experiment with the tire pressure until you find out what works for you!
