I've found running the rear at max pressure rated on the tire is 
usually best. I'm running re-inforced Conti's on the rear at 42psi (2 
psi over max), and LT rated Yokos on the front at 44-50 psi. (I 
reduce the pressure on rough roads to soften the ride a bit.)
(Because the front are not re-inforced the pressures are higher, and 
max pressure is 65psi.) The factory rating gives about 10psi 
difference for Reinf vs non-Reinf, I think.

For me, the rear seems to affect handling the most, while the front 
pressure mainly affects the ride quality. A drop of 5psi at the rear 
is quite noticeable on the highway.
