Best PSI for 33 duratracs on a 12 hour highway road trip
Heading from Va to Fla down 95 with the whole family in a few days.
I would like hear as little complaints as possible from the wife about the bumpiness.
Right now I'm at 35psi.
Wondering how low I should go and still be safe for the interstate.
Thanks!

Your pressure will increase just from driving down the road. The general rule of thumb is 1psi per 10*. I see no reason you can't go down to 28psi. Keep in mind that lower psi will yield lower MPG. I run 32psi daily all across 64, 81, and 460.

33x12.5x15 Duratracs here too. I run 32 psi on the street without any "extra" complaints. She drives a 4Runner so there's no comparison anway unless I run 15 psi and disconnected 
around 30 psi would probably give you a balance between comfort and some semblance of fuel economy on the long trip.

I had my Duratracs for 2.5 years and always kept them inflated to 28psi. They wore down evenly and provided optimal traction. Anything over 28 and I didn't like the ride quality and handling.
