Sorry, I did not mean that you were confused, just that Goodyear make it confusing by calling 2 different tires Silent Armor!. My Tire guy used to inflate mine to 41psi, however my thoughts were for around town unloaded I found that 38 psi was about right for me. On a trip loaded up I jacked it up to the 41 psi. I combined the old fashion 3psi rule together with the highly accurate
seat of the pants rule :-)
On gravel/touring roads I dropped pressure to 25psi and kept speed below about 80 for safety and to prevent to much heat buildup. I also towed my camper like this.
On sand, as I mentioned that they have very stiff side walls, I was having all sorts of problems even at 18psi. I have been experimenting and at 16 things got acceptable but the answer for me really was 14 or 15psi. I find it amazing that at these pressures you can actually feel a difference of a psi when driving, but I believe that you do.
On the hard tracks at Landcruiser Mountain Park I dropped them to 16psi and gave them heaps. Both my vehicles are relatively light however so I am unsure if this makes a difference to anything.
I found that the above worked for me, and I did not experience and problems.
