I'm gonna disagree with some of this, but I accept the fact that Bob 
finds these pressures to work well with his tires.

Yes pressure is pressure and volume is volume, but the car is 
supported by force, which is neither, but related to pressure and 
tire contact patch area. I don't have any experience with larger 
tires, but others here do. In the past, some of them have described 
using lower pressures with their larger tires to some advantage. I 
think this is worth trying. You might consider working down in the 
range of 15-18 psi.

Bob, have you tried anything lower? I suspect you'd find it to work 
even better.
