DRW vs SRW safety, tire blowout
Every time the DRW vs SRW debate starts up, dually owners always point to the safety of having 4 rear wheels in case of a blowout while driving. What I am wondering is has anyone actually experienced ...

Gdog I have a hard time believing that I should be running 35psi in my rear tires.
I could probably drop the front a bit more but I'm thinking not 15psi.
I have pretty even wear across the tire tread so I know I'm close to having a flat surface on the road.
Side treads as well as the centers were about the same so it's not crowning.
Have you ever viewed a load vs pressure chart for your size tires? If you had, you would not have a hard time believing what I told you.
Min safe pressures for all conditions (not talking aired down for off road traction) for a truck your size (unloaded) with that size tire is actually 40F/25R. But that’s a little squishy. It’s a good pressure to run for the best traction on snowy roads.
When you have the camper on, different story due to weight on the rear axle and even though the front axle weight does not change appreciably (generally), bumping the front pressure up some from what is necessary helps with minimizing tire flex due to body roll with the camper.
Good to hear your tires aren’t wearing prematurely due to being over pressure when empty.
I’d surmise that most of your miles are loaded and not empty highway miles though. As that is enough pressure to balloon the tires a bit. Especially the rear.
